Many people know about the game-changing Aeroseal duct sealing. However, the real magic is in the top-secret duct sealant (liquid solution) and how it seals duct leaks from the inside of residential and commercial ductwork systems around the world. Here’s a quick summary about it. What is Duct Sealant By Aeroseal? Also known as the Magical Sealant and “Secret Sauce,” the duct sealant is a stable, non-toxic, non-flammable emulsion of water and acrylic polymer that is aerosolized into 4-10 micron-sized particles and distributed under pressure throughout the inside of an air duct system. The following list contains key technical specifications that makes the duct sealant so powerful for contractors: Vinyal Acetate Polymer (same base of chewing gum and hair spray) Certified in Accordance with UL 1381 Low VOC Content 2 Hours to Cure 3-Year Guarantee Effective at Multiple Pressures, Temperatures, and Humidity Levels Mastic Duct Sealant versus Aeroseal (Aerosol) Duct Sealant Mastic is an older way of sealing duct leaks that is actually not as effective as sealing Another key aspect of the duct sealant is how it compares to alternatives like mastic duct sealant. Mastic is an older way of sealing duct leaks that is actually not as effective as sealing with Aeroseal. The sealant is the only option for aerosol sealants that get blown through the ductwork by a computerized system to find and seal leaks from the inside of the air ducts. Biggest advantages of Aeroseal duct sealant One of the biggest advantages of Aeroseal duct sealant over mastic duct sealant is how it’s applied. As pictured below, mastic is applied by hand. A contractor physically has to paint by numbers the mastic on the ductwork. On the right side of the picture, they’ll see the Aeroseal machine that applies the duct sealant through a computer-controlled process, resulting in less man-hours needed and better sealing results. How Does the Duct Sealant By Aeroseal Work? The award-winning, patented Aeroseal duct sealing technology magically turns the liquid duct sealant into an aerosol mist and blows it throughout ductwork to simultaneously find and seal any leaks (note: the sealant only settles at the leaks; it does not coat the ductwork).

Steam systems serve as the backbone of numerous industrial processes, providing the essential thermal energy required for a wide range of applications across various sectors. From powering machinery in manufacturing facilities to sterilizing equipment in healthcare settings, the importance of steam cannot be overstated. Improving Steam Operations American Plant Maintenance (APM Steam) offers specialized services aimed at optimizing steam systemsDespite their critical role, steam systems often operate below their maximum efficiency, pioneering to energy wastage, increased operational costs, and potential safety hazards. To address these challenges, American Plant Maintenance (APM Steam) offers specialized services aimed at optimizing steam systems. Rather than merely providing reactive maintenance solutions, they take a proactive approach, focusing on comprehensive optimization strategies that consider the entire steam system. Why Steam? The Science Behind Steam Systems Steam’s unique properties make it an excellent medium for transferring heat energy over long distancesSteam, often called the "invisible workhorse" of industry, is utilized in a myriad of applications, ranging from heating and sterilization to power generation and mechanical work. It's a versatile energy source, but its efficient use ruires a deep understanding of its properties and the intricacies of steam systems. At its core, steam is water in its gaseous state. Its unique properties make it an excellent medium for transferring heat energy over long distances. When water is heated to its boiling point, it undergoes a phase change, transforming into steam. When the reverse occurs, steam condenses to water. This process releases a significant amount of energy, which can be harnessed for various industrial applications. Core Steam Components Steam systems are composed of several key components, each with a specific role. Boilers, the heart of the system, generate steam by heating water. Piping is responsible for distributing the steam to different parts of the facility. Valves control the flow of steam, while heat transfer equipment ensures the energy is directed to where it's needed. Lastly, steam traps remove condensate to maintain efficient operation. Understanding the function of each component is crucial to optimizing the system. Challenges in Steam System Optimization One common issue is steam leakage, which can occur due to faulty valves, fittings, or failed piping. Steam leaks not only waste energy but also increase operational costs and pose safety risks to personnel. Another challenge is steam trap failure, which occurs when steam traps malfunction and fail to remove condensate from the system effectively or allow live steam to enter the condensate system. This can result to water hammer, uneven heating, and reduced steam quality. Identifying and addressing steam trap issues is essential for maintaining optimal system performance and a safe system. Additionally, improper system design and maintenance practices can contribute to inefficiencies in steam systems. Essential System Inspections Poorly insulated pipes, piping failures, poor piping practices, fouled (scaled) heat-exchanging surfaces, failed tube bundles or plates, failed condensate return pumps, inadequate ventilation, and equipment oversizing are common issues that can affect system performance. Regular maintenance and thorough inspections are crucial for identifying and rectifying these issues before they escalate. The Role of Optimization Services Specialized services aimed at optimizing steam systems are crucial for addressing these challenges effectively. Rather than merely providing reactive maintenance solutions, it is best to focus on comprehensive optimization strategies that consider the entire steam system. Steam trap surveys involve inspecting and testing steam traps to ensure they operate efficiently. This includes identifying failed traps and repairing or replacing faulty components to maximize performance. By maintaining properly functioning steam traps, facilities can minimize energy loss and reduce operating costs and operational interruptions. Evaluating Steam Performance System audits focus on evaluating the overall performance of steam systems, including pipe insulation, condensate return, air handler optimization, heat exchanger condition, and pressure-reducing stations. Engineers conduct detailed assessments to identify areas for improvement and develop tailored solutions to address inefficiencies. This may involve repairing or replacing failed equipment, upgrading equipment, or implementing other energy-saving measures. Preventative Maintenance Benefits Preventative maintenance programs aim to address potential issues before they result to system failures proactively. This includes regular HVAC and heat exchanger inspections, testing, cleaning, flushing, equipment lubrication, and monitoring system performance metrics to identify trends and patterns. By implementing preventive maintenance measures, facilities can minimize downtime, extend equipment lifespan, and reduce maintenance costs. Engineering Expertise: The Foundation of Optimization Steam system optimization lies a deep understanding of engineering principles and thermodynamics At the core of steam system optimization lies a deep understanding of engineering principles and thermodynamics. To that end, steam audits require a highly skilled team of field technicians and engineers who possess extensive experience and expertise in steam system dynamics. These professionals understand not only how steam systems operate but also why they function in specific ways. In a recent case study, APM Steam worked on a hospital where hidden steam traps had been malfunctioning for decades, unbeknownst to anyone at the facility. The condensate tank was overheating and blowing steam, and the issue had been overlooked for years. However, after a thorough inspection, the APM Steam team located the faulty steam traps and replaced them. APM Steam credited their methodical nature in finding the culprit. Fixing several small problems paved the way for the larger fix. Power of Fixing Small Issues This major fix resolved twenty years of malfunction and significantly improved the system's efficiency. This case highlights how addressing even small issues can yield substantial benefits over time. By leveraging their engineering knowledge, experts can identify inefficiencies, diagnose root causes of issues, and design solutions that enhance overall system performance. This approach goes beyond simple troubleshooting of individual components and considers the system as a whole, ensuring that all elements work harmoniously to achieve optimal efficiency. Comprehensive Optimization One of the key principles of steam system optimization is the importance of taking a holistic view. Instead of focusing solely on repairing or replacing malfunctioning components, it is best to comprehensively evaluate the entire system. By examining factors such as system configuration, original design considerations, and operational integrity, experts can identify underlying issues that may not be immediately apparent and develop strategies to address them effectively. Energy Efficiency Over Time Many facilities built in the 1960s, including pharmaceutical companies, hospitals, and universities constructed during the 1950s to 1980s, were originally well-built but without much consideration for energy efficiency. Over time, as technology evolved and energy efficiency became a priority, the knowledge of system operators and technicians dwindled. This lack of expertise proved detrimental to maintaining the original performance efficiency and operation integrity of these systems. Optimizing Legacy Infrastructure Despite being well-designed originally, changes in load, such as the increase in lab equipment and computers, as well as external factors like global warming, necessitated a fresh and comprehensive look at these legacy systems. While these systems have solid foundations, they require a thorough re-evaluation to rectify the issues that have accumulated over the years. It's crucial not to address symptoms merely but to recommission these systems with a focus on the original design, now with an emphasis on energy efficiency. Maximizing System Reliability In a community college built in the late 1970s, APM Steam was tasked with optimizing the steam system. Often, such facilities, built decades ago, pose challenges for local staff who may struggle to understand the layout and functioning of the system. The team addressed various issues, resulting to a drastic improvement in operational integrity and energy efficiency. These improvements were crucial as the college continued to expand. Comprehensive optimization extends beyond mere maintenance tasks. It involves proactive measures to ensure that steam systems are always operating at peak efficiency. This may include implementing preventative maintenance schedules, monitoring system performance metrics, and conducting regular audits to identify areas for improvement. The Importance of Expertise At the heart of a steam optimization regime is expertise: professionals who possess a deep understanding of steam system dynamics who can make informed decisions and implement effective solutions. Experts can offer an independent perspective and a fresh outlook on system optimization, resulting in unbiased assessments and recommendations tailored to specific needs. In addition to optimizing existing steam systems, expertise in steam system management is crucial during the design and commissioning phases of new installations. By involving experienced engineers from the outset, companies can avoid common pitfalls and ensure that systems are designed to operate efficiently from day one. Looking Towards the Future As industries continue to evolve and technology advances, the importance of steam system optimization will only grow. Companies that prioritize efficiency and sustainability will increasingly turn to specialized providers to ensure that their steam systems operate at peak performance. By prioritizing comprehensive optimization strategies and leveraging engineering expertise, companies can unlock significant benefits in energy efficiency, operational reliability, and overall cost savings.

It’s often said the only constant in life is change. In the HVACR industry, that phrase has been especially true. We saw another year of transitions in 2024 that included evolving efficiency and refrigerant regulations, changing corporate net zero targets, the continued emergence of advanced heat pumps, and the impact of artificial intelligence (AI) in building management.  Smart and sustainable Throughout these transformations, the industry continues to overcome challenges and innovate as we transform the places where people live, work, and play into smarter, healthier, and more sustainable spaces.    As we look toward 2025, we can expect to see a continued, industrywide focus on decarbonization, heat pump development, A2L refrigerants, and AI as regulations expand and new technologies emerge.    Decarbonization  Decarbonization continues to be a very high priority for both the residential and commercial sectors Decarbonization continues to be a very high priority for both the residential and commercial sectors. This focus has transformed the way we design and install HVAC equipment and has created tremendous opportunities for those who invest in educating themselves on the evolving technologies, regulations, and incentives. Today’s building professionals and homeowners have an unprecedented number of incentives available at the federal, state, and utility levels encouraging decarbonization transitions.  Digital and net zero services For example, tax credits such as 25C for consumers and 179D for commercial building owners were expanded under the Inflation Reduction Act (IRA) and can significantly reduce the upfront costs of high-efficiency equipment, creating a compelling offer to replace less efficient systems. In commercial buildings, combining high-efficiency HVAC equipment like electric heat pumps with digital technologies and net zero services can help empower organizations to optimize their buildings and subsystems for both the short- and long-term. Heat pumps  Heat pump technology has advanced significantly in recent years, providing an electrified, high-efficiency HVAC option for nearly all applications – even those operating within colder climates. The Department of Energy’s (DOE) Residential Cold Climate Heat Pump (CCHP) Technology Challenge has propelled the successful introduction of heat pump prototypes that can withstand subfreezing weather. Similarly, the DOE’s Commercial Building Rooftop Heat Pump Accelerator program has helped drive packaged heat pump performance toward greater efficiency for commercial and light commercial buildings located in colder climate zones.  Water-to-water heat pumps Water-to-water heat pumps can replace legacy chiller and boiler combinations without the need for major changes Innovations in commercial water-to-water compound centrifugal heat pumps are also accelerating decarbonization within building retrofits. For facilities that require simultaneous heating and cooling, such as hospitals and universities, water-to-water heat pumps can replace legacy chiller and boiler combinations without the need for major changes to the existing HVAC infrastructure. This partial decarbonization approach can help building operators achieve their decarbonization goals while also lowering operational expenses (OpEx). In many instances, this reduction in OpEx also provides a path to funding additional decarbonization strategies.      A2L refrigerants   The EPA continues to make strides in reducing the consumption and production of hydrofluorocarbons (HFCs) under the American Innovation and Manufacturing (AIM) Act. As part of the AIM Act, the Technology Transitions Program will usher in sector-based regulations beginning January 1, 2025, prohibiting the manufacturing of equipment using refrigerants with a GWP higher than 700.  New protocols As a result, new equipment will continue to hit the market throughout 2025. In tandem, many contractors and technicians will begin working with A2L refrigerants for the first time. Because these refrigerants are classified by ASHRAE as mildly flammable, new protocols for safe refrigerant servicing, storage, and transportation, and refrigerant leak detection (RDS) requirements will be necessary for some applications.   ACCA A2L refrigerant training Contractors should complete ACCA A2L refrigerant training and EPA section 608 certification With these changes, it is important to become familiar with updated codes, including UL 60335-2-40, 3rd and 4th editions, ASHRAE 15 and 15.,2, and the AHRI Safe Refrigerant Transition Task Force (SRTTF), as well as local and state regulations. Contractors should also complete ACCA A2L refrigerant training and EPA section 608 certification. Additionally, new digital tools such as RDS calculators can help contractors navigate A2L leak detection requirements and mitigation strategies while in the field.    AI and controls   AI is positioned to continue to make a huge impact in HVAC. We’re seeing more service techs using generative AI and co-pilots for troubleshooting rather than paging through manuals. At the same time, AI technology can predict if connected HVAC units may have issues, making it possible for service techs to address potential issues in their earliest stages or prevent them from happening altogether. Both of these use cases can help technicians service equipment more quickly, efficiently, and accurately, which can increase equipment longevity and reliability while reducing downtime and total cost of ownership.   Building performance AI-powered building controls can provide a holistic view into contextualized, full-building performance More HVAC systems are being equipped with AI-enhanced controls and reporting. The capabilities these tools provide can give building owners greater opportunities to optimize building performance, improve occupant comfort and well-being, and more easily reach sustainability targets. From a building management perspective, AI-powered building controls can provide a holistic view into contextualized, full-building performance, occupant experience, and sustainability. Openness and flexibility As AI becomes more commonplace, AI-centric building standards, such as ASHRAE Guideline 36, will also continue to emerge that balance sustainability with occupant comfort, health, and safety.    As we move into 2025, we can expect to see another year of equipment innovations, technology advancements, and evolving regulations. As an industry, we continue to face change with openness and flexibility. And it’s this mindset that empowers us to meet, and exceed, expectations – now and in the year to come.

As environmental regulations become increasingly stringent, the HVAC/R industry is turning to sustainable refrigerants to minimize environmental impact. A3 refrigerants—flammable gases with low global warming potential (GWP)—are emerging as a preferred choice. However, their adoption introduces additional regulatory requirements. EPA regulations To address these challenges, the industry is leveraging innovative solutions like enhanced small-diameter copper tubes, which enable compliance with EPA guidelines while maintaining performance and safety standards. In this article, we’ll explore key EPA regulations for A3 refrigerants and how small-diameter copper tubes play a vital role in optimizing system performance, ensuring safety, and achieving regulatory compliance.  Understanding A3 Refrigerants A3 refrigerants help HVAC/R systems align with current and upcoming environmental regulations A3 refrigerants are characterized by their low GWP and flammability, making them a sustainable alternative to traditional high-GWP refrigerants. Common examples include propane (R-290) and isobutane (R-600a). By reducing greenhouse gas emissions, A3 refrigerants help HVAC/R systems align with current and upcoming environmental regulations. Their benefits go beyond regulatory compliance. energy efficiency A3 refrigerants improve energy efficiency, enabling systems to operate more effectively while consuming less energy. This dual advantage of sustainability and operational efficiency reduces both carbon footprints and operating costs. As global regulations continue to phase out high-GWP refrigerants, A3 options stand out as a viable solution that balances environmental responsibility with system performance. Their efficiency and compliance capabilities position A3 refrigerants as a key player in the future of HVAC/R system design.  Advantages of Small-Diameter Copper Tubes 1. Meeting EPA Charge Limits  Small-diameter copper tubes offer a significant advantage in adhering to EPA refrigerant charge limits. With their reduced internal volume, these tubes require less refrigerant to maintain optimal performance. This feature is particularly beneficial when working with A3 refrigerants, as the EPA enforces strict charge limits to mitigate flammability risks while upholding efficiency.  2. Boosting System Efficiency with Enhanced Heat Transfer  When enhanced with internal grooves, small-diameter copper tubes maximize surface area contact with refrigerants Copper’s exceptional thermal conductivity, even with smaller tube diameters, ensures effective heat transfer. When enhanced with internal grooves, small-diameter copper tubes maximize surface area contact with refrigerants, further increasing heat transfer efficiency. This improvement translates to lower energy consumption and reduced operating costs, all while delivering reliable cooling performance.  3. Durability, Safety, and Ease of Installation  Using small-diameter copper tubes reduces the refrigerant charge required within a system, enhancing safety. Copper’s lightweight and flexible properties, especially when annealed, simplify installation, particularly in compact systems with complex configurations. Its natural corrosion resistance also ensures durability and long-term reliability, minimizing maintenance needs over the equipment’s lifespan.  Innovating for a Sustainable Future  As the HVAC/R industry transitions to A3 refrigerants, adapting to stricter EPA regulations requires innovative system designs that address safety, efficiency, and performance challenges. Small-diameter copper tubes provide a practical solution by reducing refrigerant charges, enhancing heat transfer, and delivering reliable, durable performance.  reducing environmental impact These copper innovations are especially valuable for compact, high-performance systems that demand precision and compliance with environmental standards. By embracing these advancements, the HVAC/R industry can ensure systems are future-ready, capable of meeting evolving regulations while maintaining efficiency and safety. Small-diameter copper tubes are paving the way for a more sustainable HVAC/R landscape, helping businesses succeed in reducing their environmental impact while achieving regulatory compliance. 

Until a couple of years ago, most of the talk about heat pumps occurred around this time of year, when more than half the planet prepares for an autumn cooldown. These discussions were typically limited to regions that only experienced moderate winters. But as anyone who has recently perused an HVACR trade magazine or website—or participated in an industry webinar, event, or social media conversation—can tell you, the topic of heat pumps is virtually unavoidable. Not only do heat pump discussions now occur year-round, but they’ve also ascended to consistent headline status and transcended the traditional boundaries of moderate climates.  The decarbonization megatrend One might say heat pumps have taken their place on the global stage. If you’re asking why this has happened, the answer requires just three words: the decarbonization megatrend. However, for industry professionals looking to grow their businesses, it’s helpful to gain a deeper understanding of heat pumps—how they work, ways they are currently meeting HVACR needs, and where the technology is headed for next-generation applications. Through this understanding, members of the industry can better forecast customer needs as well as identify opportunities for expanding in both current markets and, potentially, new ones. How heat pumps work—don’t let the name fool you The heat released as the refrigerant condenses is then transferred to interior spaces What heat pumps do and, more specifically, how they do it provides the key as to why they are now being considered a “hero” of decarbonization. The term can be misleading, because “heat pumps” do not generate heat. Because of this, heat pumps are being more widely embraced as the lower-carbon-emission alternative to combustion-based heating technology that uses, for example, fossil fuels.  Instead of creating heat, heat pumps extract heat energy from where it’s not needed and move it to where it is needed. When a heat pump is in heating mode, its refrigerant evaporates as it absorbs heat from the outside. The heat released as the refrigerant condenses is then transferred to interior spaces. In warmer weather, a heat pump kicks into cooling mode and the process is reversed, as heat is extracted inside and released outside. This non-combustion process of moving heat from one place to another provides several potential benefits to society: Heat pumps support the megatrend toward decarbonization. They replace fossil-fuel heating with high-efficiency technology. They can be paired with lower-global-warming-potential (GWP) A2L refrigerants—such as R-454B and R-32—to further increase environmental benefits, while offering similar performance to the legacy R-410A. They offer the ability to tap into alternative energy sources, such as industrial waste heat as well as heat sourced from the air (ambient), ground (geothermal), or lakes/ponds (water). Meeting today’s needs—these aren’t your grandfather’s heat pumps Heat pump technology has been commercially available and in use since the 1950s. Early versions of heat pumps were essentially reversible air conditioning units, and most used traditional refrigerants—like R-22 and, more recently, R-410A. These units performed well and operated safely using lower-toxicity, nonflammable (A1) refrigerants. However, they were known to sometimes struggle at lower ambient temperatures. As often happens in the world of science and technology, challenges drive the search for solutions. Today, we’re seeing innovations that result in efficient, effective cold-climate heat pumps that optimize various components, such as compressors, heat exchangers, expansion valves, and their controls. Thanks to these innovations and others, the U.S. and other countries are experiencing broader heat pump adoption and, in turn, supporting progress toward decarbonization.  Heat pump technology has been commercially available. Increasing heat pump accessibility and viability in more places and spaces is also critical to the HVACR industry’s commitments to the environment—and its need to heed regulations advancing the transition to systems reducing climate impact. Emerging systems use mildly flammable (A2L) refrigerants. They are similar in design to legacy systems and include modifications to mitigate risks associated with the change to A2Ls. Where things are headed—heat pump technology is just getting started Even with the significant advances we’ve seen in colder-climate heat pumps, there is still untapped potential in terms of what the technology can achieve. We can expect to see continued innovation as end-user needs and environmental priorities continue to evolve. Some foreseeable growth areas for heat pumps include: Traditional applications—that is, moderate climates Expansion into nontraditional climates—heating in very cold climates and cooling in hotter regions Domestic water heating, replacing fossil-fuel systems Leveraging a variety of heat sources—geothermal, air-sourced, and water-sourced Harnessing waste heat generated by energy-intensive industrial processes Use of lower-GWP A2L refrigerants System optimization will also drive greater use of lower-GWP A2L refrigerants, such as R-454B Supporting these growth areas will be innovations that optimize high-performance, high-efficiency delivery of extracted heat, using a combination of traditional and new split-ducted, ductless/mini-split, and mono-block technologies. System optimization will also drive greater use of lower-GWP A2L refrigerants, such as R-454B, while limiting the use of highly flammable refrigerants such as R-290. Refrigerant selection will also play an increasingly important role and may offer additional opportunities for application-specific technology. As heat pump applications expand, we can expect to see greater focus on selecting the optimum refrigerant to use as the working fluid. Criteria will weigh system design, operating conditions, and other priorities against key refrigerant properties: Physical—boiling point, vapor pressure, density, and material compatibility Thermodynamic—cooling/heat capacity, energy efficiency, pressure-enthalpy (PH) curves Environmental—ozone depletion potential (ODP) and global warming potential (GWP) Safety and health—flammability and toxicity Conclusion: There’s strong and ample reason to “stay pumped” Over the past several years, members of the HVACR industry have enthusiastically embraced new heat pump solutions. Evolving heat pump technology and expanding applications will continue as the industry progresses along the path of more energy-efficient, lower-GWP, and more sustainable new-generation and next-generation heating and cooling. This, coupled engineering and science that leverages untapped heat pump potential, will mean more opportunities for HVACR contractors to deliver new options to the markets they serve. With a strong understanding of their customers’ individual heating and cooling needs, climate challenges, and sustainability goals, contractors can confidently select the best heat-pump refrigerant solution.

The system is weatherproof, indoor, or outdoor, and communicates using radio frequency (RF). AHR Expo 2025 made a strong case that investing in smart controls will improve operational efficiency, reduce downtime, and enable predictive maintenance. Hydronic Systems for Data Center Cooling One major player is Bell & Gossett/Xylem, whose hydronic cooling systems target data center market The rise of data center cooling solutions was another recurring theme at AHR. One prominent player is Bell & Gossett/Xylem, whose hydronic cooling systems target the data center market. The company’s e-1531X and e-1532X smart pumps offer enhanced energy efficiency and a larger "efficiency island." These systems are designed to meet the growing demand for sustainable data center cooling, providing a net-zero roadmap. As data center energy consumption rises, hydronic solutions offer a scalable, efficient approach to thermal management. Heat Pumps Expand Capabilities and Market Reach Heat pumps continue to dominate as a top energy-efficient alternative for commercial and residential applications. Companies such as Danfoss, Mitsubishi, and Samsung are pushing the boundaries with heat pumps that operate in extreme temperatures. Danfoss is progressing forward related to four application areas at AHR 2025--heat pumps, data centers, RTU/DOAS, and retail/refrigeration. Emphasis is on lower emissions and better energy efficiency. Midea drew a lot of attention at AHR 2025, including modular air handler Midea drew a lot of attention at AHR 2025, including their modular air handler – the  EVOX G³ – that breaks down into three pieces for easy movement and installation in any of six configurations. They are also opening showrooms throughout the country so consumers and contractors can see and touch the products. Integration with renewable energy sources Johnson Controls-Hitachi mini-splits have a self-cleaning feature called FrostWash Johnson Controls-Hitachi Air Conditioning’s Hitachi mini-splits have a self-cleaning feature called "FrostWash;" they intentionally build a frost layer on the coil so the fine particulates can be captured and then melted away, thus avoiding mold and other contaminants. It can be used in lieu of UV light, which damages plastics. The heat pump market is growing rapidly, and advancements in low-temperature performance and integration with renewable energy sources will drive adoption. The Drive Toward Sustainability Sustainability is a recurring theme at the expo, with manufacturers prioritizing energy-efficient equipment, smart automation, and low-GWP refrigerants. Companies like Lennox, and Rheem are launching highly efficient packaged rooftop units and unitary heat pump systems. Grundfos’s distributed pumping technology and Ziehl-Abegg’s ZAcore intelligent control platform further demonstrate the industry's push toward lower energy consumption and minimal environmental impact.

TE Connectivity’s main product categories for the HVAC market are power interconnects, signal interconnects, magnet wire for motors, and heat-shrink tubing to seal against environmental factors. component materials The company works with HVAC original equipment manufacturers (OEMs) to solve challenges such as harsh environments, safety, and power and signal usage. Although components are a “small” element when an OEM assembles an HVAC system, their impact can be big. For example, a tiny component not producing a spark could make it safer to introduce mildly flammable refrigerants into the newer HVAC systems.  Addressing material compatibility Raising questions about component materials not degrading by exposure to newer chemicals over time Also related to the transition to newer refrigerants is the issue of materials compatibility, raising questions about component materials not degrading by exposure to newer chemicals over time. “The big trends in HVAC are higher efficiency, more intelligence (in the context of the Internet of Things), faster data transmission, better safety, and more reliability,” says Joseph Burch, Business Development Manager for TE Connectivity’s Appliance Business Unit.  product portfolio TE Connectivity is a brand associated with high quality. OEM customers think of the company (rather than lower-cost competitors) when they have a critical design and/or they need to access TE Connectivity’s vast product portfolio spanning a variety of markets. Broadly speaking, their products include wire-to-board connectors and wire-to-wire connectors at a range of amperages, voltages, and sealing requirements. The broad product line means there are likely solutions within the TE Connectivity family for many OEM design needs.  durability and sustainability “We try to meet customers where they are and where the supply chain is,” says Burch. In addition to dealing directly with OEMs, the company works around the world alongside contract manufacturers of various subsystem components. Currently, TE Connectivity is a global leader with a strong focus on reliability, durability, and sustainability in its connectivity and sensor products. They serve a range of industries, including HVAC, and are known for their contributions to technological advancements.  the efficiency of heat pumps Higher efficiency requires precise monitoring of electrical signals and transmission of data For TE Connectivity and others, driving development in the HVAC market is the transition to heat pumps, a rapidly growing equipment category. Achieving the improved efficiency of heat pumps raises the stakes from a component perspective boosting the need for sensors and faster data transmission. Higher efficiency requires precise monitoring of electrical signals and transmission of data. Integration of heat pumps with renewable energy sources, such as solar, requires even more connections and better communications.  rapid data transmission The ability of newer systems to adapt to changing environmental conditions depends on the fast transmission of sensor data to guide operation. In effect, rapid data transmission, using signal interconnects, makes it possible to achieve higher efficiencies that are critical to newer systems. The faster signals are communicated, the more efficient the systems are. Larger systems are increasing the demand for higher power, and efficiency standards are driving more sensing needs, as is the trend toward smart homes.  flame retardant Addressing one of the big challenges in the HVAC market, TE Connectivity sells its products to withstand harsh environments such as moisture and vibration. In a typical HVAC scenario, half the system is located outdoors and exposed to weather and other elements. From a safety perspective, electrical connectors on HVAC units are unattended 24/7, so reliability is critical, and materials must be flame retardant and withstand high temperatures. Parts must adhere to the Underwriter’s Laboratories (UL) VO flammability rating, which means a flame extinguishes within 10 seconds and there is no dripping.  competitive analysis TE Connectivity’s business development teams seek broadly to assess the size of a market, such as HVAC, and the magnitude of the opportunity in each market for their various product lines. In addition, the company attends trade shows to see the latest trends to seize the opportunities to promote the company’s brands and products to the market.  TE Connectivity engineers conduct “in-house teardowns” of existing OEM products to analyze how various components are used and how they might be improved to refine the overall solution. TE Connectivity’s competitive analysis labs are frequently looking for new opportunities to innovate. address design-related issues A “system architecture team” within the engineering group is tasked with understanding how systems work TE Connectivity’s engineers also work directly with OEM customer engineers to address any design-related issues. The field engineering team works on the “front line” with customers and provides feedback to the company’s development engineering team, which gets involved as needed. A “system architecture team” within the engineering group is tasked with understanding how systems work, new technologies, new regulations, and innovations, and establishing roadmaps to forecast needs looking ahead five to ten years.  Multiple design trends “Our engineering teams are problem-solvers, focused on connectivity problems across many industries,” says Joshua Poterjoy, Senior Manager, Product Development Engineering. Multiple design trends are among the factors driving product needs, such as miniaturization, higher-speed data transmission, the need for ergonomic and modular designs (for ease of assembly), and components designed for assembly and packaging automation. Components also adhere to Restriction of Hazardous Substances (RoHS) directives that avoid the use of hazardous substances in electrical and electronic equipment.  ease of installation GRACE INERTIA series signal connectors provide fine-pitch connections for smaller electronics Creating components to deploy ergonomic and modular designs promotes ease of installation, both for assembly by the OEM company and for installers in the field. Components are designed to be as simple as possible while achieving all the operation and reliability standards. Quick-connect and twist-and-lock systems provide an assuring “click” when a robust connection is made. For example, the company’s Universal MATE-N-LOK multi-position power connectors are often used in the HVAC market from powering control cards to motors to fans. Also, the GRACE INERTIA series signal connectors provide fine-pitch connections for smaller electronics.  TE Connectivity’s history TE Connectivity’s history can be traced back to the founding of AMP Incorporated in 1941, which pioneered the development of electrical connectors. In the 1990s, AMP became part of the Tyco International conglomerate, further expanding and diversifying. In 2007, Tyco International split into three independent companies, including Tyco Electronics, which focuses on connectivity and sensor solutions. Tyco Electronics changed its name to TE Connectivity in 2011.

SNAP Rule 26 marks an important milestone in the transition from commercial refrigeration to new refrigerants. The rule lists refrigerant substitutes that provide a spectrum of technological solutions to meet required performance, global warming potential (GWP), safety, and environmental standards.  SNAP stands for Significant New Alternatives Policy, a program by the U.S. EPA (Environmental Protection Agency) under the Clean Air Act. In general, the program aims to evaluate and regulate substitutes for ozone-depleting substances, considering their overall risks to both human health and the environment. Impact of SNAP Rule 26 Final SNAP Rule 26, Protection of Stratospheric Ozone, lists acceptable substitutes in commercial and industrial refrigeration. SNAP Rule 26 will be effective July 15, 2024. The incorporation by reference of certain material listed in the rule is approved by the Director of the Federal Register as of July 15, 2024. The incorporation by reference of certain material listed in the rule is approved by the Director of the Federal Register “To date, the SNAP program has provided a very effective framework for evaluation and approval in support of innovation and the transition to new technology,” says Andrew Pansulla, Technical Service Engineer, The Chemours Company, a global chemistry company that provides a range of refrigerant products. We asked Pansulla to elaborate further on the impact of SNAP Rule 26 and what lies ahead. Q: How will the Rule’s finalization impact various commercial refrigeration sectors? Pansulla: The rule’s finalization will impact commercial refrigeration in several ways. Areas, where impact will likely be seen, include providing more acceptable refrigerant options, adherence to updated standards, new equipment design standards, and the exemption of propane from the venting prohibition for refrigerated food processing and dispensing equipment. These impacts could trigger changes in operational, manufacturing, and environmental compliance strategies in the commercial refrigeration sectors. SNAP Rule 26 will enable the adoption of the listed substitutes, including Chemours Opteon™ refrigerants, with global warming potential (GWP) lower than existing refrigerants. This rule does not require any changes to existing equipment and will impact only new equipment that uses the specific substances referenced in the SNAP rule. Q: What is the outlook for additional requirements for safe handling and use of alternative refrigerants? What specific safety standards are expected or appropriate? Pansulla: As part of the comparative risk framework used by the EPA to assess new alternatives, the EPA considers and implements use conditions that will ensure the safe use of products. These use conditions rely upon existing safety standards (e.g., UL and ASHRAE) which are available at the time the rule is finalized. In the case of SNAP Rule 26, many of the use conditions require adherence to UL 60335-2-89 and ASHRAE-15-2022. These standards are reviewed and updated periodically to maintain relevance with the products subject to the standards. Q: What are any limitations of the use of A2L refrigerants under SNAP Rule 26? Pansulla: There are two main categories of limitations under SNAP Rule 26. The first, as mentioned above, is the adherence to specific safety standards that apply to refrigerants that are designated as mildly flammable (A2L). The second is based on the GWP of the refrigerant. In the case of the A2L refrigerants subject to SNAP Rule 26, the EPA imposed conditions on the type of equipment and specific circumstances in which the substitute may be used. For example, the EPA is permitting the use of R-454A in supermarket systems, but only on the high side of a cascade system, or when the refrigerant charge capacity is less than 200 pounds. Q: Which new-generation A2L refrigerants are fit for which commercial refrigeration applications? Pansulla: Under SNAP Rule 26, the EPA deems R-1234yf, R-1234ze(E), R-454C, R-455A, R-457A, and R-516A as acceptable subject-to-use conditions for various commercial refrigeration applications. This selection is primarily driven by these refrigerants having GWPs under 150. However, certain applications necessitate refrigerants with higher GWPs due to unique performance characteristics. For example, R-454B and R-32 were listed for industrial process refrigeration with exiting fluid temperatures below minus 30 degree Celsius because these two specific refrigerants have lower boiling points than the other six less-than-150-GWP alternatives. However, it is critically important to consider the additional use conditions when designing equipment with refrigerants that have a GWP greater than 150. Q: So various equipment needs different refrigerants? Pansulla: The EPA purposefully lists several different refrigerants in each application to allow for equipment manufacturers to consider a variety of different factors that go into refrigerant selection, such as energy efficiency, capacity, normal boiling point, temperature glide, cost, safety, and use conditions. There is no one-size-fits-all solution for the entire commercial refrigeration industry. Q: How can commercial refrigeration businesses achieve a smooth transition to A2Ls? Pansulla: Keys to a smooth transition to A2Ls include understanding what refrigerants the EPA has approved as acceptable substitutes under the SNAP program, the sector-based GWP limits imposed by the Technology Transitions Program under the American Innovation and Manufacturing (AIM) Act, and which refrigerants provide the best combination of technical performance and environmental characteristics. Many resources are available to navigate the regulatory landscape and select the best low-GWP refrigerants to meet the needs of this industry. Working with companies like Chemours, who has nearly a century of refrigerant innovation and experience, is a great first step in the transition process. Q: What is the “staying power” of A2Ls — based on their chemistry, sustainability, and other attributes, combined with regulations such as SNAP Rule 26? Pansulla: The identification, selection, and development of new refrigerants that deliver required performance while meeting increasingly stringent environmental standards is a challenging process. With the identification of certain hydrofluoroolefin-based (HFO) refrigerants as an alternative to meet these criteria came a new safety classification. These HFO-based refrigerants are classified as A2Ls. While slightly more flammable than existing hydrofluorocarbon-base (HFC) refrigerants, HFOs are much less flammable than hydrocarbons, which are classified as A3 (two categories higher on the ASHRAE flammability spectrum). Moreover, such refrigerants offer an excellent alternative to substances with higher toxicity, such as R-717. The listing of A2L refrigerants in SNAP Rule 26 clearly indicates that such refrigerants can be used safely in commercial refrigeration as well as many other applications, which are subject to the SNAP Program, when adhering to the applicable safety standards.

With a reputation for uncompromising integrity, HDG Legacy is an experienced voice in the hospitality industry for those looking to build, own, and operate hotels. As both a respected developer and preferred management company, the Legacy team employs its core values of teamwork, communication, innovation, leadership and resourcefulness, and has an established reputation for positively impacting the hospitality sector. Currently, Legacy manages and maintains nine hotels that it owns, with its tenth opening July 2025. Rising energy and water costs  A commitment to improving and innovating hotels means that Legacy is alive to the economic challenges facing hoteliers, not least in operational challenges because of rising energy and water costs. With profit margins often razor-thin, even small innovations can mean the difference between profit and loss, so it was no surprise that Legacy looked to Anacove’s unique AI- and Cloud-powered Smart Thermostats, Leak Detection and Asset Management systems to help give its hotel clients the edge in their energy and water management. Anacove’s Smart Thermostats  “One of my core beliefs is that operating a business that respects the environment in terms of how resources are utilized is important just because that's the right thing to do – but there's also an economic benefit,” explained Navroz F. Saju, Founder and Principal at HDG Legacy. “We initially tested Anacove’s Smart Thermostats across our express properties, before piloting them in one of our larger hotels, and we were so impressed with the results (we actually have the data showing the savings for 2024-25 thus far – very impressive!) that we are looking to roll out the solutions across our other properties.” Electricity consumption reduced He continued, “We started using Anacove Smart Thermostats in July 2024 at the Holiday Inn Express Crystal River, and based on historical data and usage, electricity costs on our utility bills are 35.94% lower per occupied room.” “The Holiday Inn Express & Suites Silver Springs-Ocala’s electricity costs were 33% less than what we’d budgeted for per room, with the Holiday Inn Express & Suites Inverness-Lecanto coming in at 43% lower than budgeted in electricity usage.” Features of Smart Thermostats  Anacove’s Smart Thermostats are innovative IoT devices with advanced sensors Anacove’s Smart Thermostats are innovative IoT devices with advanced sensors that monitor temperature, humidity, air quality, barometric pressure, current weather conditions, daylight conditions and guest presence. They seamlessly integrate with HVAC systems through existing hotel WiFi infrastructure, allowing for centralized control throughout the hotel. This enables continuous optimization of each room, regardless of occupancy status, leading to immediate and sustained cost savings. Unlike other occupancy-sensing thermostats, Anacove Smart Thermostats remain active even when guests are asleep or have left their pet in the room. Optimizing HVAC Cycles  Learning from each room’s thermal behavior – heating and cooling coefficients – the thermostats optimize HVAC cycles, resulting in reduced peak energy consumption, and maintenance of guest comfort with less energy usage. “I have been very pleased with the transition to Anacove Smart Thermostats, and we will continue to replace older, less efficient thermostat technology with Anacove thermostats,” added Saju. “They are easier to operate – for staff and guests – and install than others on the market – irrespective of their superior energy-saving performance – and are incredibly responsive.” Anacove’s staff and support Such was their ease of use that Legacy’s skilled maintenance staff installed the Anacove Smart Thermostats themselves, but Saju is keen to point out how engaging Anacove was throughout the process. “Their support has been excellent. Even though the thermostats are easy to install and operate, if there is ever a question that needs answering the Anacove team is there to back us up very quickly and in a very expert way,” he said. “I've been very comfortable with their price point – I actually think that their thermostat pricing is the most competitive I have found – and with their after sales service and the technology’s ease of use they are very customer-centric indeed.” Anacove’s AI-enabled water management systems  In addition to rolling out Anacove’s Smart Thermostats incrementally across his hotels, Saju is also deploying the company’s AI-powered, cloud-maintained Toilet Leak Detectors and Asset Tracking Systems. The AI-enabled water management systems go beyond basic leak detection. While sensors installed in water tanks or behind walls detect even the tiniest leaks, it’s the AI that identifies anomalies, pinpoints problem areas, and alerts maintenance teams before the issue escalates – saving water, money, repair costs, and mitigating guest inconvenience. Anacove’s Asset Management System  Anacove’s Asset Management System equips hotel assets such as luggage carts, rollaway beds, cribs, housekeeping trollies and other movable items with location tags, which, thanks to the cloud-maintained AI system, helps to track down missing items, triangulating their exact positions, streamlining retrieval, reducing loss, and improving overall resource management. “We all expect a lot from our hotel’s front desk,” said Saju. “They’ve got to check people in, the phone's ringing, someone wants a bandage and then suddenly someone will check in and say, ‘where's the luggage cart?’” “The fact that they're immediately able to log in to the Anacove cloud dashboard on their phone and see exactly where the cart is – usually in a guest’s room – is an incredible time-saving benefit, enabling them to locate the cart’s exact location so that they can repurpose the cart for another guest’s use. In the past they would have to ring around guests’ rooms to find it – a waste of time and valuable resources.” Anacove AI cloud brain The performance of all four Anacove technology services (thermostats, toilet leaks, staff and asset trackers) are monitored and analyzed by the company’s AI cloud system, effectively a brain hovering over key operational areas of the hotel that make intelligent decisions. This ‘Anacove AI cloud brain’ – the only system of its kind – looks at the whole hotel as a single living entity, autogenerating reports that allow hoteliers to clearly see the return on their investment. The AI-enabled, cloud-connected energy management solution uses one inclusive dashboard, with a data-rich, monthly ‘flash report’ that provides a summary of how much energy has been saved, what's going on in terms of potential toilet leakage, etc. Easy and energy efficient  Overall, Saju is delighted with not only Anacove’s innovative, unique, AI-powered, cloud-connected devices, which are exceeding Anacove’s own expectations, but also by the company’s service and support. “They advertised a saving of about $12.00 per-room per month for the Smart Thermostats, which was pretty significant, but we're beating those numbers,” he explained. “Overall, all their technology is easy to install and use. There are huge savings, and – importantly – our general managers are very happy!” “Anacove’s after-sales service has also been second to none, and they have been incredibly receptive in helping us adapt the systems to our own requirements. I am a huge fan of Anacove and the team there; they're good people and I'm so glad that we're able to work together.”

When they are one of the largest beverage distributors in the U.S., it’s crucial to stay ahead of the curve on everything that drives customer satisfaction, corporate responsibility, and a strong bottom line. Hensley Beverage Company did exactly that when it collaborated with Chemours and American Refrigeration Supplies, Inc. (ARS) to implement a system utilizing a new-generation A2L refrigerant, Chemours Opteon™ XL20 (R-454C). Completed in 2023, the installation paves the way for companies throughout the commercial refrigeration industry to embrace refrigerant technologies that are both cost-effective and environmentally sustainable. Situation The company recently ended an acquisition that grew its distribution footprint into New Mexico Hensley Beverage, a Phoenix-based beverage wholesaler, supports a customer base of more than 9,000 accounts and more than 2,500 individual products, operating out of six locations across Arizona.  The company recently completed an acquisition that expanded its distribution footprint into New Mexico, making it one of the largest family-owned and operated beverage distributors in the nation. As it grows, Hensley remains committed to maintaining exceptional product integrity, upholding its multi-generational family business legacy, and supporting a variety of environmental objectives. These factors, coupled with the current regulatory landscape (notably, the phasedown of legacy hydrofluorocarbon (HFC) refrigerants), have put Hensley’s focus on ways to upgrade its refrigeration systems. Phasedown of HFC refrigerants For the past several years, Chemours, ARS, and Hensley have worked together to retrofit the distributor’s existing R-22 and R-404A systems to Opteon™ XP40 (R-449A), a hydrofluoroolefin (HFO) blend offering zero ozone depletion potential (ODP) and a significantly lower global warming potential (GWP) than legacy products. However, with the ongoing phasedown of HFC refrigerants under the U.S. EPA’s American Innovation and Manufacturing Act (AIM), the teams began weighing the benefits of an even bolder upgrade. “Hensley Beverage is proud to partner with Chemours, TBSI, and ARS to help develop innovative solutions and responsible business practices that drive sustainability in our community. These groundbreaking results are a culmination of partnership and collaboration. It is refreshing to work with three organizations that are this passionate about developing pioneering products that will help shape a better future for the communities we serve,” Alex Dunn SVP of Operations, Hensley Beverage.  Solution Chemours recommended bringing Opteon™ XL20 (R-454C) into Hensley’s refrigeration plan Even as Chemours, ARS, and Hensley continued to strategically employ retrofit solutions in some areas, they explored options that would put the company in a stronger position for the long term. Chemours recommended bringing Opteon™ XL20 (R-454C) into Hensley’s refrigeration plan. A mildly flammable refrigerant with an ASHRAE A2L safety classification, Opteon™ XL20 is designed for use in new equipment, so Hensley identified an old R-22 system near the end of its life that was ideal for replacement by a new system using Opteon™.  Opteon™ XL20 has been used for several years in Europe and is expected to become the new norm in the U.S. by 2026, based on the current direction provided by the EPA. Leveraging its experience in Europe, the Chemours team of technical service and business development resources is prepared to support end users as they consider trial installations using A2L refrigerants. Features of Opteon™ XL20 Opteon™ XL20—the future of sustainable low- and medium-temperature refrigeration GWP of 148 (a 96% reduction versus R-404A)  Zero ODP Enables much higher charge sizes than highly flammable A3 refrigerants Is a close performance match to R-22 and R-404A Offers the optimum balance of performance and environmental sustainability Provides an easy, cost-effective alternative to legacy refrigerants in new equipment applications Utilizes well-known technology for ease of service and maintenance Benefits of HFOs Hensley was an early adopter of Opteon™ XP40, retrofitting equipment to experience better “Hensley was an early adopter of Opteon™ XP40, retrofitting equipment to experience better environmental outcomes, as well as high performance in low- and medium-temperature applications. Experiencing these benefits of HFOs whet their appetite to ask, ‘What next?’ With a strong dedication to supporting their communities and the environment while operating an efficient and thriving business, Hensley is a company that pushes the envelope." "Chemours was ready with our next-generation Opteon™ XL20—that will ensure they achieve maximum performance, operating efficiency, and sustainability," Joe Martinko President, Thermal and Specialized Solutions, Chemours. New low GWP refrigerant  “Our industry is undergoing some of the most significant regulatory changes in history and will be for the foreseeable future. ARS was excited to work with Chemours and be a part of the launch at Hensley of the new low GWP refrigerant." "It’s been a privilege for ARS to help bring together such an excellent group of partners for this project—and to install a first-of-its-kind system right here in Tucson, a community we’ve proudly served since 1948,” John White President, American Refrigeration Supplies, Inc.  Opteon™ XL20 properties ASHRAE Number: R-454C Composition Weight%: R-32/R-1234yf 21.5/78.5 Molecular Weight: 90.8 g/mol Normal Boiling Point: -45.6 °C (-50.0 °F) Critical Pressure: 4318.9 kPa (626.4 psia) Critical Temperature: 85.7 °C (186.2 °F) Liquid Density at 21.1 °C (70 °F): 1058.2 kg/m³ (66.1 lb/ft³) Ozone Depletion Potential (CFC-11 = 1.0): 0 AR4 (AR5) GWP (CO₂ = 1.0): 148 (146) ASHRAE Safety Classification: A2L Temperature Glide: ~6 K (~10.8 R) LFL (UL 60335 2-89 WCF): 0.291 kg/m³ (0.018 lb/ft³). Collaboration and Installation The installation brought together additional resources from the HVACR industry, including Copeland and Heatcraft Refrigeration Products— two ARS manufacturing partners—as well as Technical Building Services, Inc. (TBSI), the local HVACR service provider. As HVACR technology providers helping customers achieve their sustainability, decarbonization, and regulatory compliance goals, Heatcraft and Copeland had the knowledge and experience of emerging A2L requirements and the capabilities to support the project. TBSI was selected as the contractor for installation and servicing.  Use of R-22 in other Hensley systems Installation, evacuation, and setting methods were very similar to the recent refrigerants With the team assembled, Chemours took the lead on the project, ensuring that the contractor, Hensley’s service personnel, and others involved were certified through the ESCO Institute’s A2L refrigerant training program, and answering any questions from the local authorities.  After safely recovering the R-22 for use in other Hensley systems, the team from TBSI started removing the existing Keg 6 equipment, hanging new evaporator coils, and running new refrigerant lines. Installation, evacuation, and charging procedures were very similar to the current refrigerants in use by industry, making for a time- and cost-efficient process. Next generation of climate technology “Copeland has always been focused on not just setting the standard in climate solutions with pioneering brands in compression, controls, software, and monitoring—but pioneering the evolution in this space. Our role in the system design and installation for Hensley was right in our wheelhouse. What we accomplished together demonstrates that by bringing together energy-efficient products, regulation-ready solutions, and expertise, we can revolutionize the next generation of climate technology for the better,” Brian Schroeder Engineering Manager, Refrigerants, Copeland.  “Our tools and gauges were already enabled for the R-454C refrigerant. The startup and charging of both systems went pretty smoothly. TBSI is proud to have participated in the project at Hensley and, by doing so, adding to the variety of equipment we’ve worked on since founding our business in 1990. This was a great opportunity to grow our experience with A2Ls,” Sergio Pelayo Vice President, TBSI.  Copeland monitoring data Copeland applied monitoring units to the systems that capture nearly two dozen data points every second To make sure the system performed as expected, Copeland applied monitoring units to the systems that capture nearly two dozen data points every second. The data has shown that the systems are running as designed.  “We are thrilled with the results of the R-454C project with Hensley Beverage. As we continue our journey toward new regulation compliance, this successful collaboration has been instrumental in leveraging Heatcraft’s new product design efforts, with A2L refrigerants being an important part of the mix. We are poised to lead the industry and provide more customers like Hensley with cutting-edge solutions that drive their success,” Bob Landi Vice President and General Manager, Heatcraft Refrigeration Products. Summary Influenced by upcoming regulatory changes and stronger organizational ESG commitments, the commercial refrigeration industry’s transition to lower GWP refrigerants is inevitable. Opteon™ refrigerants provide organizations with lower GWP options that can help extend the useful life of their systems, as well as new equipment options that enable decades of reliable operation. Moreover, these systems answer the consumer preference for businesses that utilize responsibly manufactured products and support a greener environment. Hensley’s approach demonstrates an ideal way for companies to meet the needs of refrigerating their products while following the guidelines of the HFC phasedown. It’s important to assess where your equipment is in its lifecycle and determine if it makes the most sense in terms of budget, performance needs, and corporate vision to (1) retrofit existing equipment for more efficient and sustainable operation or (2) replace it with A2L refrigerant technologies and products.

The emphasis on sustainable processes has never been greater than in today’s marketplace. Environmental conservation must be considered in every phase of appliance design and in every step of the product lifecycle.  Product designers use sustainable materials to limit carbon footprint, efficient and reliable components are chosen to reduce environmental impact during product operation, and, after the end of a product’s useful life, responsible companies must even plan for recycling and disposal.  TE Connectivity’s Industrial Technology Index, a survey of global companies focused on the innovation culture of engineers and executives, showed that innovation and sustainability are business priorities for most engineers and executives alike. Sustainable practices are now being integrated early in the innovation process, providing more opportunities to limit the environmental impact of new products. Sustainable design considerations throughout the product life cycle Sustainable Design Considerations TE’s connectors play a vital role in enabling the safe, reliable and efficient interaction of a wide variety of essential components. A growing emphasis on sustainable practices has compelled the team to develop sustainable products for various types of equipment. Designs for sustainability replace virgin materials that have large carbon footprints with recycled or renewable, biological-based alternatives.  Designs for sustainability replace virgin materials that have large carbon footprints Likewise, efficiency improvements during manufacturing, as well as more reliable, energy-saving connector designs, further limit the environmental footprint of these products. TE’s cluster block products, used for compressor applications like air conditioners, heat pumps, and refrigerators, have been redesigned with this sustainability in mind. These innovative products will help enhance the reliability of compressors, while reducing energy consumption and minimizing carbon footprint. Enhanced Safety, Performance and Productivity Reducing the temperature of connectors in operation results in less wasted energy. This can improve the performance of the compressor which translates to better appliance efficiency.  The sustainable cluster block achieves this goal with an additional contact beam, shown in Figure 2, that minimizes electrical contact resistance, optimizing the energy transmission, reducing temperature rise and providing the required connection. Additionally, the innovative lead-in alignment feature, illustrated in Figure 3, helps to error-proof the connection, improving safety as well as productivity of automated assembly processes.  The sustainable cluster block achieves this goal with an additional contact beam Potential health hazards The cluster block uses a renewable, plant-based material (Figure 4) that can be sustainably produced with minimal impact to the environment.  This high-performance material meets the stringent International Electrical Code (IEC) with flammability ratings tested to UL 94 V-0, CTI 600V and GWEPT 750°C (1380°F) no flame requirements. Made up of 50% castor bean oil, the material is halogen-free which further limits the potential environmental impact. This material reduces the carbon footprint by more than 45% during production, use and disposal while also eliminating potential health hazards.  Conversion of renewable, plant-based material into halogen-free, flame-resistant resin for the cluster block housing Minimizing environmental impact TE’s new cluster block (Figure 5) was designed to minimize environmental impact by reducing consumption of natural resources, minimizing waste and promoting renewable energy. To mitigate climate change, the cluster block connector features 19% lower plastic usage and 26% lower metal usage, when compared to legacy connectors (Figure 6).  The cluster block connector features 19% lower plastic usage and 26% lower metal usage The sustainable cluster block will help TE contribute to maximizing the safety, performance and sustainability of compressor applications. This technology is a key step in meeting the growing demand for cost effective, environmentally friendly solutions that are compatible with modern automated assembly processes. As the appliance industry continues to evolve, sustainable connector designs will undoubtedly play a key role in shaping the future of compressor applications and beyond.

Paragon House – an 11 story teaching block at the University of West London (UWL), has recently replaced its gas boiler heating system with a ground-breaking first for Europe and the UK, by Finn Geotherm installing three x 210kW Panasonic air-to-water heat pumps with a bespoke cascading thermostatic control system to heat the entire building. The University of West London were looking to improve the energy performance of the building in a more sustainable way, reducing their carbon footprint and energy consumption, with the help of a Salix funded government grant (the UK Government’s Public Sector Decarbonization Scheme (PSDS) and the Low Carbon Skills Fund (LCSF)). Paragon House installs Panasonic heat pump system UWL appointed Ameresco as the main energy improvement contractor for the project UWL appointed Ameresco as the main energy improvement contractor for the project with Finn Geotherm as the contractor who specified and installed the 3 x 210kW Panasonic heat pump system, along with a bespoke cascade thermostatic control system that links with the building’s BMS. Paragon House is situated in a prestigious London location adjacent to the M4 with a mix of classroom and lecture theatres across 11 floors. Sustainable energy efficient system The main challenge for the project was that the University ideally wanted minimum internal disruption and an energy efficient system that could link and work with their existing pipework, radiators, cassettes and fan coils. A further challenge was lifting the three large 210kW units, each 6 square meters and weighing just over two tons onto the roof of the 11 story building. Detailed structural surveys were carried out to ensure the weight and distribution of the units at roof level would work effectively and safely. Panasonic air source heat pumps Guy Ransom, the Commercial Director at Finn Geotherm commented, “Originally it was thought that the best solution to meet the heat load for the entire building would be a ground source heat pump system but on initial surveys and inspections, it became apparent that the drilling of bore holes would be impossible given the ground space available and the proximity of the building to the M4 motorway and other busy London road networks.” Guy Ransom adds, “We have worked with Panasonic air source heat pumps over a number of years now and have developed a trusted two-way partnership with the team and where Panasonic has become our manufacturer of choice – we respect the quality of the units – they do what they say they can do.” Panasonic 210kW heat pump units installed Panasonic 210kW heat pump units installed at Paragon House were the first of their kind in the UK The Panasonic 210kW heat pump units installed at Paragon House were the first of their kind in the UK and Europe to be installed – the units offer outstanding efficiency with extremely high SEER and SCOP figures, can operate in temperatures as lows a -17 degrees Celsius in heating mode, are quiet in operation, offer a customizable design with capacities from 20k to 210kW, and can be integrated into a BMS control system. The team at Finn Geotherm worked with Panasonic’s European R&D and UK teams to obtain test data to support the specification of the units. The two teams liaised over a number of weeks to verify the data, ensuring the required range of output and input temperatures would work effectively on the bespoke thermostatic cascading control system. Maximize the use of the heat pump The aim was to maximize the use of the heat pump use when a back-up system was insisted on by the client for the Paragon House project. Guy Ransom stated, “We worked closely with the wider team at Panasonic and carefully laser measured and assessed the heat loss for each area of the building to ensure that the units would be able to distribute a similar level of comfort to the existing gas boiler system.” He adds, “The Panasonic system now installed at Paragon House was the first of its kind in Europe – this ground-breaking project pushes the envelope for similar large renovation projects in the future that are looking to decarbonize their heating systems - the customer is very happy with the end result.” Panasonic system lowers the carbon footprint The Panasonic system has lowered the carbon footprint of the property The Panasonic system has lowered the carbon footprint of the property and is highly energy efficient to run with little impact on the interior pipework and space within the building. The units are located on the roof to ensure they are discreet, quiet and unobtrusive to the surrounding area, having very little impact on the day to day running of the building during installation. A construction of support spreader beams and plates was designed to distribute the load within the tolerance of the roof area. University of West London pleased with the results Claire Willits, the Director of Property Services at the University of West London (UWL) said, “The University of West London has been very pleased with the results of the project and having now been through our first winter running on the new systems we can safely say the technology works!” Claire Willits adds, “This project has made a significant contribution in our carbon reduction journey and has given us reassurance that change for the better of the environment can also be cost-effective and deliver a practical operational solution.” Exceptional energy savings It is estimated that Paragon House will receive energy savings in the region of 1,058,000 kWh per year It is estimated that Paragon House will receive energy savings in the region of 1,058,000 kWh per year. Considering the other two Panasonic installs at UWL, the total amount of energy saving is expected to be in excess of 500 tons of CO2 per annum. The above project was recently announced as the award winner of the National Renewable Heat Project of the Year at the Energy Efficiency Awards 2022. Seamless design and installation Harvey Loyal, Specification Sales London for Panasonic, stated “The control of the 210kW units were new to the market when Finn Geotherm came to us with the project – we worked with the wider Panasonic technical team and Finn Geotherm to provide a seamless design and installation.” Harvey Loyal adds, “As this was a European first and so for peace of mind, the original boilers were kept as a back-up should the outside temperatures reach -5 degree or lower. 12 months following the installation, Paragon House has confirmed the boiler system has not once been utilized and the heating produced from the Panasonic Air-to-Water system fully meets the heating requirements of the building.” Since the initial installation of Panasonic air source heat pumps at Paragon House, Finn Geotherm has installed similar Panasonic systems in several other similar buildings across UWL, as well as many other large projects in and around the London area.
