Once initiated, thermal runaway will likely result in a fire, but with the right detection technology it is possible to contain the consequences. Spyglass™ Xtend triple-infrared flame detector Integrated high-definition CCTV video delivers clear, rapid imaging of fuel fires like gasoline and jet fuel On stand B39, Teledyne GFD, which has its UK manufacturing facility just 8 km west of Glasgow in Renfrew, will be shining the spotlight on four key technologies. The recently introduced Spyglass™ Xtend triple-infrared flame detector offers the simultaneous detection of both hydrogen and hydrocarbon fires. It boosts safety in environments where hydrogen flames can spread to co-located systems or nearby equipment and start fires involving hydrocarbon fuels that are invisible to a hydrogen-only detector. Integrated high-definition CCTV video delivers clear, rapid imaging of fuel fires like gasoline and jet fuel, while the near-IR video option detects fires caused by hydrogen and methanol, making it ideal for BESS applications. Five selectable sensitivity levels are available. Utility grid integration projects Other instruments of note at All Energy 2025 will include the tried and tested GD10P infrared (IR) gas detector, as well as the GS700-Hydrogen, a high-performance and highly flexible all-in-one instrument that is able to detect both hydrogen and natural gas in utility grid integration projects. Fully ATEX-certified instrument means utilities can quickly determine the source of gas leaks Whether it is 100% hydrogen, hydrogen blends, or natural gas, the portable GS700-Hydrogen simplifies gas detection in applications that include outdoor/indoor leak detection, purging, barholing, and pipeline gas testing. Providing both safety and peace of mind, the fully ATEX-certified instrument means utilities can quickly determine the source of gas leaks, saving valuable time and reducing detection-related costs such as unnecessary excavations. Teledyne GDCloud’s capabilities Also on show will be Teledyne GDCloud™, a user-friendly new cloud solution that enhances gas detection measurement by recording hazardous events. Users can take advantage of this technology to help ensure regulatory adherence and streamline safety programmes. Among Teledyne GDCloud’s most powerful capabilities is visualizing detailed gas sensor readings from field sessions. Users can trace the route that a technician takes during investigations via advanced location mapping functionality. This capability enables breadcrumb mapping to identify the exact locations that correspond to gas readings logged by the detector. Teledyne GFD’s expertise Users can also interact with dynamic charts and tabulated data displays to reveal further insights Users can also interact with dynamic charts and tabulated data displays to reveal further insights into field activity and events. The same four technologies will also take center stage at the World Hydrogen Summit 2025, where visitors will find Teledyne GFD at booth A93. In fact, such is Teledyne GFD’s expertise in the hydrogen arena that it has been invited to deliver a presentation at the event entitled ‘Regulatory Framework and Compliance along the Hydrogen Value Chain’. Future gas detection challenges At World Gas Congress, a flagship gas and energy industry event staged once every three years, Teledyne GFD will again present these technologies to visitors from booth Z12 in hall D.

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.

The HVAC/R industry is in the process of a major shift as A2L refrigerants become the standard in residential and commercial system HVAC. This change is being propelled by stricter environmental policy and advancements in refrigeration technology. However, the transition is not without its hurdles, posing new considerations for system owners, technicians, and equipment manufacturers. Favor of GWP alternatives The Environmental Protection Agency (EPA) has established clear guidelines to phase out hydrofluorocarbons (HFCs) in favor of lower global warming potential (GWP) alternatives.  The 700 GWP limit imposed by the EPA, forced manufacturers away from non-flammable A1 to mildly flammable A2L refrigerants for comfort cooling chillers and air-to-air unitary equipment. R-410A split systems  Under current regulations, R-410A split systems can still be installed until January 1, 2026 Under current regulations, R-410A split systems can still be installed until January 1, 2026, but manufacturers had to halt production of R-410A-based equipment by January 1, 2025.  As for packaged systems, which are fully assembled and sealed at the factory, sales will remain permitted until January 1, 2028, but only for equipment manufactured before 2025. Adaptation of A2L refrigerants These regulatory milestones mark a significant step toward a new era in HVAC/R technology, emphasizing sustainability and compliance with modern environmental standards. While the transition is underway in our market as we speak, there are some key factors that play into the adaptation of A2L refrigerants. How we implement, gain familiarity, and roll out these systems provides challenges.  System Design Modifications ASHRAE Standard 15 first added these requirements in its published version of 2019 ANSI/ASHRAE Standard 15 is widely recognized as the preeminent guide for the safe use of refrigeration equipment, as evidenced by its inclusion in building codes at the state and local level. ASHRAE Standard 15 first added these requirements in its published version of 2019. For high-probability systems, in which the basic design or the location of components is such that a leakage of refrigerant from a failed connection, seal, or component could enter the occupied space, these requirements underwent major revisions for the 2022 version, with intent to better harmonize with the requirements in UL 60335-2-40. Modifications in HVAC system design The transition to A2L refrigerants necessitates modifications in HVAC system design to ensure compatibility and safety. One significant consideration is component compatibility; all system components, including compressors, heat exchangers, and expansion devices, must be rated for A2L refrigerants to ensure optimal performance and safety.  Failure to use appropriate components could lead to operational inefficiencies or increased safety risks. Component Testing/Approval Requirements UL 60335-2-34 is a safety standard that applies to motor-compressors used in refrigeration systems UL 60335-2-34 is a safety standard that applies to motor-compressors used in refrigeration and air-conditioning systems. The UL 60335-2-34 6th edition was established in 2017 as the safety standard for compressors, introducing several key updates. One major change is the requirement for a new Maximum Rated Current marking, ensuring clear identification of electrical ratings. Additionally, the standard introduces various new testing methods for motors and their protective mechanisms to enhance safety and reliability.  Testing methods outlined in UL 207 UL207 covers “Refrigerant-Containing Components and Accessories, Nonelectrical” which are components Danfoss refers to as “line components”, such as filter driers, expansion valves and pressure regulating valves.  The testing methods outlined in UL 207 include burst pressure tests, fatigue tests, and hydrostatic tests to verify nonelectrical refrigerant-containing components and accessories. UL 207, which remains a referenced standard under UL 60335-2-40, has been reapproved for use with R-454B. Dealing with A2L refrigerants Compliance can be achieved through burst testing at five times the maximum pressure rating Unlike A1 refrigerants, where leaks at gaskets or mechanical seals were not a concern at twice the maximum pressure, such leaks now pose a significant issue when dealing with A2L refrigerants.  Compliance can be achieved through burst testing at five times the maximum pressure rating or by conducting a fatigue test at three times the maximum pressure rating without the product bursting or leaking from any mechanical connection. Implementation: Choosing a Solution Understanding what makes sense for your sector of the market for this transition is paramount in how OEMs will implement (and many already have) A2Ls into the next generation of equipment. Let’s zoom in and look at the HVAC segment related to commercial A/C units. The two main A2L refrigerants that were approved via SNAP rule 26, being used to replace R-410A in the 2025 transition requirement, are R-32 and R-454B. These two offer different approaches to the design requirements needed to be implemented. R-454B Danfoss has a selection tool called Cool Selector® 2 that is free to download online While no refrigerant is a direct replacement for R-410A, R-454B which has a GWP of 466, is considered a relatively close “drop in” solution. As such, most major components of the system, such as compressors and heat exchangers, can usually stay the same size. This is the lowest GWP solution available in the “high-pressure” range. With that being said, R-454B operates at lower pressures than R-410A, it also operates at lower mass flows than R-410A. This can leave your current liquid line, liquid line solenoid, expansion device slightly oversized. It is considered good practice to verify the sizing of these existing components when introducing R454B. Danfoss has a selection tool called Cool Selector® 2 that is free to download online. This can help you in verifying Danfoss components.  R-32 If the transition to A2L refrigerants is going to coincide with a major redesign of that unit, then R-32 (GWP 677) may be an option for your transition. R-32 will work at overall higher operating pressures and provide a significant increase in capacity vs R-410A. But with this comes the reality that most components in the system, possibly including piping sizes, will need to be changed to better suit the use of R32. R32 as a refrigerant, will also generate higher discharge temperatures than systems running with R-410A, creating a problem that manufacturers will need to account for in low ambient heat pumps and high condensing temperature environments. Leak Detection and Mitigation Refrigerant leak detectors must be installed in every unit with individual circuits charged with 4lbs As A2Ls pose a higher flammability risk, effective leak detection and mitigation strategies are essential for maintaining safety in environments where A2L refrigerants are used. Refrigerant leak detectors must be installed in every unit with individual circuits charged with 4lbs of A2L refrigerant or more.  More details on charge limits for systems and what mitigations requirements are needed can be found in UL60335-2-40 Annex GG. These detection systems enable quick identification and response to refrigerant leaks, reducing the potential for accidents or equipment damage. Danfoss leak detectors use thermal conductivity technology, were among the first to be UL-approved a year ago and come in a variety of configurations for HVAC/R equipment manufacturers. Proper mitigation strategies Proper mitigation strategies are crucial for preventing refrigerant accumulation in case of leaks. They must be tied into the unit control scheme. Disengaging any heating elements eliminates the possibility of ignition sources. Engaging evaporator fans increases circulation, ensuring that any leaked refrigerant is quickly dispersed, minimizing the likelihood of hazardous concentrations forming. In addition, per UL60335-2-40, service and maintenance procedures must incorporate regular leak inspections as a standard practice. Refer to ASHRAE 15 or UL60335-2-40 for further readings and requirements. Service and Familiarity Technicians must gain a version of the parts of A2L refrigerants and are required to pass an A2L test While manufacturers focus on design changes to accommodate the A2L transition, industry members who will install and service units also must adjust to the changing landscape of refrigerant. Technicians must gain an understanding of the characteristics of A2L refrigerants and are required to pass an A2L certification test under EPA Section 608.  Looking Forward This phase of transition is better conceptualized as a mid-term solution. The American Innovation and Manufacturing (AIM) Act was passed in 2020. This directed the EPA to address hydrofluorocarbons (HFCs) and phase down production and consumption of HFCs by 85% by 2036. It is likely in the future, we will see another step in transitions to ultra-low GWP Refrigerants such as R-290 (A3 class), R-1234ze, or R-515B. Before the AIM Act, individual states like California were looking to regulate their own refrigerant marketplaces. As adoption of new EPA regulations might be slowed under the current U.S. administration, it is uncertain if any future deregulation by the federal government could lead to some states restarting their own regulation programs. But as we stand now, lower GWP A2L refrigerants still continue to grow in the marketplace.

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.

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.

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.

Revised building codes, based on model “I-Codes” developed by the International Code Council (ICC), are being widely adopted to allow A2L refrigerants to be used in comfort air conditioning applications. Previously, the use of A2L refrigerants, which are “mildly flammable,” was not allowed by building codes in force in 2021 and before because of safety concerns.   benefits of A2Ls However, the benefits of using A2Ls instead of refrigerants with higher global warming potential (GWP) have led to their acceptance as a replacement for hydrofluorocarbons (HFCs) in air conditioning applications. In response to the greater acceptance, driven by EPA refrigerant cutbacks, ICC has revised their building codes to permit the use of A2Ls, and local jurisdictions are in the process of adopting the revised building codes.  2024 I-Code changes Approved code changes in the 2024 IBC, IFC, and IMC allow commercial and residential use of A2L refrigerants The 2024 I-Code changes facilitate compliance with new refrigerant requirements and support producers and refrigerant appliance manufacturers already transitioning to lower-GWP solutions such as A2Ls.  Approved code changes in the 2024 International Building Code (IBC), International Fire Code (IFC), and International Mechanical Code (IMC) allow commercial and residential use of A2L refrigerants to replace refrigerants. The use of A2L impacts all three intertwined sets of building codes, which have been undergoing the three-year amendment process since 2021.  model codes and standards The International Code Council is a global source of model codes and standards and building safety solutions that include product evaluation, accreditation, technology, training, and certification.  ICC is working with the Air-Conditioning, Heating, and Refrigeration Institute (AHRI) to partner with the construction industry and to facilitate legislation to navigate this positive change.  The IBC, IMC, and IFC code revisions, all managed by ICC, have been approved; two finalized codes were published earlier in 2023 and the third is being released in November 2023. Building, mechanical, and Fire codes Building code revisions align with established safety standards regarding handling of A2L refrigerants The Building and Fire codes cover storage of A2Ls in a warehouse, while the Mechanical code covers requirements for installing equipment that uses A2Ls.   Building code revisions align with established safety standards regarding handling of A2L refrigerants, including ASHRAE 15 (Safety Standard for Refrigeration Systems), UL 484 (Room Air Conditioners), UL/CSA 60335-2-40 (refrigerant detector requirements) and UL/CSA 60335-2-89 (enabling higher charge limits for flammable refrigerants).   requirements of ASHRAE 15 In buildings where HVAC machinery is installed, the code changes reflect requirements of ASHRAE 15, such as no equipment with open flames, elevated temperature limits in a room, and refrigerant detection requirements that trigger a mechanical ventilation system in case of a leak. Any piping that carries A2L must be labeled as flammable with a warning. Condensers and evaporators will need to carry the familiar triangular flammability labels and “risk of fire explosion” verbiage, all consistent with the ASHRAE 15 standard.   Diamond-shaped labeling An interlock requirement ensures ventilation processes are implemented in case “Diamond-shaped labeling must be displayed on packaging, storage, and containers so that anyone coming into a room knows there is flammable refrigerant there,” says Jim Cika, a director of technical resources for the International Code Council.   The codes cover safety requirements such as leak detection, ventilation requirements, and “flammable” labeling. An interlock requirement ensures ventilation processes are implemented in case of a detected leak of A2L gas.  storage and warehousing “The biggest concern is proper storage and warehousing,” says Jim Cika. “Due to flammability, there are significant additional storage requirements compared to HFC. Distributors have to be prepared with appropriate space and labeling requirements, especially when the materials are being stored in bulk and large quantities.”  A2L code provisions The code changes are required to enable builders to transition to A2L refrigerants ICC has created a website that provides relevant A2L code provisions including documents with specific wording related to code changes. Some states adopt the codes state-wide, while other “home-rule” states leave the adoption of the codes to the individual local jurisdictions. The code changes are required to enable builders to transition to A2L refrigerants.   new codes ICC has been publicizing the code changes with the help of a grassroots effort with AHRI. “We have put our code provisions out there so everybody knows what they need to be concerned about and to be ready for inspection,” says Cika. The new codes are coordinated with the EPA and the requirements of the SNAP programs. “We are all on the same page,” he says.  installation of new equipment After 2025, new equipment will no longer use HFCs but will need to use A2Ls or another low-GWP refrigerant Up to 25 lbs. of A2L refrigerant can be transported without any hazardous material restrictions; in effect, installers and contractors can transport A2L just as they did HFC.  Transitioning to A2L refrigerants involves the installation of new equipment since the legacy equipment that uses HFCs is not compatible with the new refrigerants. After 2025, new equipment will no longer use HFCs but will need to use A2Ls or another low-GWP refrigerant. transition to A2Ls Technicians will still be able to service and maintain existing equipment installed in the field for the rest of its useful life. With equipment using both types of refrigerant operating among various customers, technicians will need to be able to work on either type of system during the transition period.  Phased down and limited supplies of HFCs, as ordained by EPA regulations, will likely push installers and their customers to the newer technologies using A2Ls. 

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 a company is 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  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, USA. Hensley remains committed to maintaining exceptional product integrity, upholding its business legacy The company recently completed an acquisition that expanded its distribution footprint into New Mexico, making it one of the nation's largest family-owned and operated beverage distributors. As it grows, Hensley remains committed to maintaining exceptional product integrity, upholding its multi-generational family business legacy, and supporting various environmental objectives.  Upgrading refrigeration systems 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.

In line with the UK’s Net-Zero targets, local governments are transitioning communities to a greener future. Kemsley Community Centre, based in Sittingbourne, Kent, United Kingdom (UK) were looking for a more energy efficient and sustainable system to heat and cool their large and multiple areas of the community center, in order to replace a 1960’s oil-fired system. Phoenix ACR, specialists in AC and refrigeration, specified a Panasonic R32 split system with 4 x 20kW PACi outdoor units and 11 of the Panasonic PACi NX Elite range of wall mounted indoor units with nanoe X. Panasonic R32 split system installed The new system needed to meet the needs of the entire community center, covering the main hall, bar area and reception area. Each section required units suited to the individual area, which could seamlessly combine and function under a single control system. The Panasonic PACi NX Elite range was specified by installer, Nathan Bell, the Managing Director of Phoenix ACR, who explains “We have worked with Panasonic a lot in the past, so we knew its range was the best to deliver the efficiency, reliability and value for money that was key to this installation. The energy-saving design and high efficiency makes the Panasonic units ideal for this project.” Panasonic PACi NX Elite wall mounted indoor units The PACi NX Elite range allows a great amount of flexibility in design and install The PACi NX Elite range allows a great amount of flexibility in design and install, which was crucial to ensuring we could adapt to the needs of each room, providing the perfect solution for the customer. The addition of nanoe X technology, which inhibits viruses and bacteria, was a key benefit of the Panasonic units, to help provide a better indoor environment for the community center staff and its users in a post-pandemic world.” Featuring nanoe X technology In the main hall and bar area, 11 Panasonic PACi NX Elite wall-mounted units with nanoe X technology were installed. These are especially beneficial for high ceiling areas, such as found in the community center. The reception area has two PACi ceiling suspended units, with the slim design making them more discreet for the smaller room, along with being one of the quietest units currently on the market. Facilities Trustee of Kemsley Community Centre, David Grawler, said “It is so important that we provide a sustainable future for our community. Phoenix ACR recommended this solution, and we are very happy with how it meets our energy efficiency needs. With our old system, if we hired out a single room, we would end up having to heat the entire building.” David Grawler adds, “The new Panasonic system allows us to control all units as one for the entire building, but also enables us isolate the individual spaces, adding a new way for us to function in a more energy efficient way, without having to compromise on comfort.” PACi NX Standard and PACi NX Elite ranges The PACi NX Standard and PACi NX Elite ranges provide high quality heating and cooling The PACi NX Standard and PACi NX Elite ranges provide high quality heating and cooling, boasting top class SEER ratings of A++ and SCOP ratings of A+ and A++ at 10kW respectively.
