Although the European Union is several steps ahead in the transition away from hydrofluorocarbon (HFC) refrigerants, members of the HVACR industry in other countries currently find themselves in a more urgent situation when it comes to stepping down HFCs and stepping up use of new-generation hydrofluoroolefin (HFO) refrigerants and emerging A2Ls. EPA’s AIM Act This is especially true in the U.S., where 2024 kicked off with an additional 30% reduction in HFC production and consumption under the EPA’s American Innovation and Manufacturing (AIM) Act. With every phasedown comes a decreasing supply. And with every passing year, more HFC-charged equipment reaches the end of its lifecycle—or at least requires repair.  Given the regulatory outlook, supply trajectories, global sustainability imperatives, and increased customer demand for businesses to be environmentally responsible, HVACR shops can no longer be “thinking about” how they will transition. It’s time to start engaging in activities to help ensure your business transitions as smoothly as possible.  Transcritical CO2 systems Many business advantages come with incorporating HFOs—especially A2Ls—into your portfolio It’s also important to understand that the transition is not just about “following rules.” Many business advantages come with incorporating HFOs—especially A2Ls—into your portfolio. Consider how proactively leveraging these advantages can support your business goals and growth. A2Ls, which include HFOs and HFO-blend refrigerants, offer similar operating characteristics to legacy refrigerants and a safer profile than ammonia and hydrocarbon refrigerants, and they are more energy efficient than R-410A and transcritical CO2 systems. Not only can A2Ls protect our planet because of their lower global warming potential (GWP) and ability to increase system efficiency, but they can also lower the operating cost throughout the lifecycle of refrigeration equipment. The sooner you can put these advantages to work, the stronger your position among customers will be—whether they are driven by environmental concerns, cost savings, better performance, safe environments, or all the above. Five key steps for refrigeration transition   So, with all this motivation behind you, how do you get started? Here are five key steps you can take to facilitate the refrigeration transition. Help ensure refrigerant supply by practicing the “Three Rs.” The Three Rs, also known as a refrigerant management plan, help ensure there is enough HFC supply to meet your needs as well as those of the industry. As HFC production and consumption phasedowns continue—resulting in reduced supply availability for servicing existing equipment—this step becomes increasingly critical. Consistently follow a process of refrigerant recovery, recycling, and reclamation. When servicing equipment, or taking it out of use, be sure to recover every possible bit of the refrigerant. Then recycle it for reuse or send it to a certified reclaimer to be reprocessed and reintroduced into the supply stream as refrigerant that meets all virgin purity specifications. Following a solid refrigerant management plan will also support your circularity and sustainability goals. Educate yourself on A2Ls. Learning about A2Ls means becoming knowledgeable about the many aspects driving their global adoption. By understanding their benefits over legacy refrigerants, differences in how they are used, safety considerations, and which OEMs are adopting them, you will be able to properly guide your technicians and customers, as well as outline a business strategy for introducing A2L equipment into your offerings. This knowledge becomes increasingly valuable as the world confronts climate challenges more aggressively than ever—as evidenced by the accelerated adoption of A2L refrigerants in North and South America, and their wide availability in Europe and Japan. Moreover, A2Ls are expected to see broad adoption in the U.S. in the near future, as more states amend building codes and standards to allow their use.  Be loyal to training. You should consider training for you and your technicians to be a part of your business’s DNA. Whether we’re talking about mildly flammable A2Ls or other HFOs or HFCs, staying current and keeping your technicians trained is highly important. Training is a top priority for ensuring safe handling, optimal equipment performance, and quality work that supports the integrity of our industry. In fact, there’s the potential for authorities to make it mandatory. But whether training is voluntary or mandatory, contractors should call on companies such as Chemours and industry associations that offer programs that train “the trainer” and the technicians.   Be prepared to communicate with your customers. Steps two and three, education and training, will give you a leg up when it comes time to have the “repair, retrofit, or replace” conversation with a customer. When this moment is imminent, make sure you’re prepared to have the discussion in a way that gives your customers all the options and helps them make an informed decision that is best for their home or business. Also, educate yourself on all the refrigerant options available today, so you can point out the advantages of one over another. These should include energy savings, environmental benefits, and performance attributes, plus the cost of purchasing new equipment or retrofitting existing equipment compared to continual repairs. Consistently use your trusted supplier. As HFCs are phased down, there will be a greater incentive for them to enter regions illegally. In addition to thwarting environmental goals, illegal refrigerants typically have poor quality makes them unsafe and inefficient for use. The best way to protect your crews, customers, and business is to continue to use your trusted supplier every time. Also stay away from the temptation of “too good to be true” prices, as these can be tied to counterfeit or illegal refrigerants. Reasonable transition Remember that phasedowns like those being implemented through the AIM Act have been structured to support a workable, reasonable transition. So, while there is a need to put your plans in motion, there is no need for panic.  You can ensure yourself of a smooth transition and reap the benefits of it by committing to starting these five steps now and continuing them consistently throughout the year. If everyone in the industry does their part, we can all support businesses, customers, and the planet.

This time of year, a lot of planning is underway. Companies throughout the HVACR industry are mapping out the best path to maintain their current level of business, pursue growth while staying in their lane, or expand into a new area based on changing customer needs and industry opportunities. Whether you’re a small family-owned residential HVAC shop, a major player in commercial HVACR service or manufacturing, or anywhere in between, it’s helpful to be aware of the strong dynamics that promise to wield their influence industrywide in the year ahead.   regulatory influences These megatrends differ from the regulatory influences the industry has been under since 1989 when the Montreal Protocol started the phaseout of ozone-depleting substances, such as chlorofluorocarbons (CFCs). Since then, regulations including the Kigali Amendment and U.S. EPA American Innovation and Manufacturing (AIM) Act, both designed to phasedown the consumption and production of high global warming potential (GWP) hydrofluorocarbons (HFCs) have created a steady stream of influence that will continue for years to come. transition to lower-GWP solutions In planning for 2024, companies must remain aware of the scheduled step-downs of HFCs In planning for 2024, companies must remain aware of the scheduled step-downs of HFCs and follow processes that support a smooth industry transition to lower-GWP solutions.   Superimposed on these regulations are several megatrends, many of which are also driven by environmental needs and the universal aim to repair a planet in crisis. However, unlike regulations, the benefits of paying attention to these influences go beyond adhering to the rules so as not to risk fines.  Benefits of megatrends The motivations behind incorporating megatrends into business plans can include widening your customer base by attracting those who chose vendors demonstrating sustainability commitments, being prepared to meet emerging customer demand, achieving operational cost and/or energy savings, staying resilient during unforeseen changes or challenges in the industry, and more.  Here are a few top megatrends I foresee surging ahead to influence HVACR in 2024.  Heat Pumps -The “Heroes” of Decarbonization  As our industry and others not only stay focused on a zero-net-carbon future but also continue to accelerate efforts to get us there, we’re going to see heat pumps become more important and prevalent. Through their thermal management process, heat pumps don’t create heat, but instead extract and move it from one place to another. This makes heat pumps a viable replacement for traditional heating methods, such as burning coal, wood, or propane that come with significant carbon emissions.   Thermal management technology Instead of simply allowing that heat to dissipate in the atmosphere, heat pumps can recover heat In addition, the thermal management technology of heat pumps can be used to convert waste heat to energy. This capability is especially advantageous to processes and industries, such as lumber drying that generate a ton of heat. Instead of simply allowing that heat to dissipate in the atmosphere, heat pumps can recover heat and then harness it for energy.  Efficiency Lastly, technology has improved considerably, making heat pumps more energy efficient, even in colder climates. Along with the innovative properties of hydrofluoroolefin (HFO) thermal management fluids, which offer zero ozone depletion potential (ODP) and very low GWP, heat pumps are positioned to be even more advantageous than fossil fuels.   As businesses and industries pursue aggressive benchmarks for decarbonization, across the board from homes to businesses to manufacturing facilities, we can expect to see a growing preference for heat pump use.   Circularity’s Criticality  Through the 2010s and into the 2020s, the concept of circularity, putting practices in place so that materials remain in circulation and never become waste has taken root. It finds itself on the priority list for every business in every industry. The sustainability of our planet depends on it. So does business strategy. Sustainable circularity pathways Maximizing the efficient use of all our resources is essential for the strength of our industry Circularity offers more than a demonstration of responsibility to our planet. Maximizing the efficient use of all our resources is essential for the strength of our industry and the businesses that support it. This move toward establishing sustainable circularity pathways can be seen much like step-down regulations since circularity will be a steady influence on HVACR for the foreseeable future.  Importance of F-gases However, in the context of 2024 megatrends in HVACR, the criticality of circularity will elevate the importance of F-gases, especially HFOs, and draw attention to so-called “natural” refrigerants like ammonia, CO2, and propane.  For example, CO2 refrigerants are not reclaimed. Instead, they are vented into the atmosphere as greenhouse gas emissions that can remain in the atmosphere for hundreds of years. On the other hand, F-gases can be reclaimed, recycled, and reused across multiple applications.  Reclaim, recycle, and reuse This translates into maximizing resource efficiency and generating less waste generation and lower emissions. We can expect to see the industry work strongly to encourage and support refrigerant reclamation, recycling, and reuse, creating a preference for HFO-driven solutions over non-circular fluids such as “natural” refrigerants.     Emerging Immersion Cooling  Data centers allow us to do pretty much everything we consider a modern-day necessity Our world today is founded on data centers, nearly 8,000 of them worldwide, according to recent estimates.  These data centers allow us to do pretty much everything we consider a modern-day necessity and/or convenience from high-powered computing and gaming at faster speeds to AI and electric vehicle technologies. Challenges with traditional air-cooling These data centers work nonstop and incredibly hard, generating tremendous amounts of heat as they do so. The traditional method of air-cooling these centers is quickly becoming undesirable, due to the massive amount of water, energy, and other resources consumed in the process.   Benefits of immersion cooling Immersion cooling, a process in which hot equipment is submerged in a thermal management fluid offers much more efficient cooling, without the tremendous use of resources. Given its many benefits, we can expect to see two-phase immersion cooling (2-PIC) grow exponentially, replacing air-cooling methods. Ideally, data centers will convert to 2-PIC, which, unlike single-phase immersion cooling, operates in a contained system without the need for pumps and external heat exchangers.   2-PIC 2-PIC will bring more attention to the cooling sector as well as a greater appreciation and desire Though seemingly a bit removed from HVAC, the topic of 2-PIC is being discussed more frequently, and the use of technology is increasing. As a result, 2-PIC will bring more attention to the cooling sector as well as a greater appreciation and desire for thermal management solutions that support the environment and modern life. It will also drive innovations that could prove beneficial for many aspects of HVACR.  Workforce Shortages  There are approximately 2,000 open HVAC technician positions in the U.S., leaving a gap of about one-third of what the industry needs and threatening the operations of businesses of all sizes. This, combined with new technologies, including A2L refrigerants that require special safe handling considerations means companies must place an even higher priority on training. The crews in the field today need to be proficient in working with HFCs, HFOs, A2Ls, and possibly even older legacy refrigerants that are “hanging on” in some applications.  New equipment manufacturing regulations Shifts in equipment for installation and maintenance will further increase the need for a fully-trained technician It’s also important to note that, as of Jan. 1, 2025, the AIM Act will begin enforcing regulations on new equipment manufacturing. For example, all new AC equipment will be required to operate with refrigerants carrying a GWP of 700. We’ll see the elimination of new equipment using R-410A, and manufacturers will move away from low-to-medium temperature refrigeration systems using R-404A, R-407A, R-448A, and R-449A. The resulting shifts in equipment for installation and maintenance will further increase the need for a fully trained technician workforce that can cover all the bases.  Conclusion  In 2024, newer, better refrigerant technologies will be commercialized, and their adoption will continue to expand, requiring companies to have a strong refrigerant management plan in place. Moreover, as has been the case throughout history, people in and outside our industry will look to be part of the next big thing. For HVACR, the “dinosaurs” of industrial gases, such as CO2, ammonia, and propane which were brought into use over a century ago, may get another look. But they will be challenged by the same inherent problems that led to them being largely abandoned. Innovation with a new environmental profile Meanwhile, an innovative new generation of F-gases will offer a better path forward in terms of higher performance and an environmental profile meeting the demands of today’s world. As several megatrends “make their move” and influence HVACR in 2024, the industry will continue to focus on ensuring equipment and the refrigerants that power it work to achieve lower GWP, greater decarbonization, and an overall healthier planet. 

According to some recent estimates, the cooling industry accounts for approximately 10% of global carbon dioxide (CO2) emissions. To place this in perspective, the transportation sector, as the highest contributor, accounts for approximately 20% of global CO2 emissions. While some may see this as a “glass half empty” scenario, the better approach is the one taken by key players in the HVACR space. As we see it, because the cooling industry has been a source of significant emissions contributing to global warming, we have a huge opportunity to turn the tide through innovative chemistry and technology. Certainly, having a sizable impact on improving the health of the planet won’t be as fast as “flipping a switch.” Nor should it be. What is required is a thoughtful, well-planned and well-supported strategy that allows everyone involved in the HVACR industry—from refrigerant and equipment manufacturers to retailers, service shops, and end users—to transition to better solutions in ways that best work for them as well as for our planet in crisis. Industry’s Contributions to CO2 Emission CFC use has been reduced to less than 1% of where it was in the 1980s This transition is already well underway. Long before recent estimates about the industry’s contributions to CO2 emission were shared, providers in HVACR got to work innovating solutions to take refrigeration off “the environmental hot seat,” much like we did decades before when scientists pointed to chlorofluorocarbons (CFCs) as a major cause for ozone layer depletion. If you recall, the 1987 Montreal Protocol unified many countries in the effort and drove industries to find and use CFC alternatives, such as the solutions found in zero ozone depletion potential (ODP) hydrofluorocarbon (HFC) refrigerants. CFC use has been reduced to less than 1% of where it was in the 1980s, and it’s expected that, except for the polar regions, the ozone layer will be completely recovered by 2040.  Industry’s contribution to global warming To minimize the cooling industry’s contribution to global warming, we started by looking at two areas that stood to make a major impact—improving the overall energy efficiency of equipment and lowering the overall climate impact associated with HVACR. While not the sole solution for making these improvements, we knew refrigerants could play a significant role. Companies like Chemours went to the labs and harnessed the power of chemistry to innovate a new class of refrigerants consisting of hydrofluoroolefins (HFOs) and HFO blends.  In addition, OEMs engineered new systems and retrofit solutions that worked with these HFOs In addition, OEMs engineered new systems and retrofit solutions that worked with these HFOs, which have zero ODP, offer a global warming potential (GWP) significantly lower than the legacy products they replace, and enable equipment to run with better energy efficiency. At present, in terms of refrigerants, the industry is headed toward an HFO-centric—and more specifically, a low-toxicity, low-flammability A2L-centric—future. A2Ls and megatrends Industry and the world operate under the influence of several megatrends that continue to put focus on emerging next-generation refrigeration. These include: Fast-tracking the move toward decarbonization Circularity—maximizing the use of renewable energy and minimizing waste through reclamation and the infinite reusability of materials Shortage in skilled workforces—making it imperative for businesses to have technicians who can work with HFCs, Class A1 and A2L HFOs, and even CFCs and HCFCs Increased demand for products that not only support a greener environment but that are manufactured responsibly Business of HVACR Solutions need to offer versatility to support everyone from small family-owned shops These megatrends will continue to influence refrigerant transitions. So will the business of HVACR. In addition to supporting the environment, refrigerants and equipment need to cool effectively and efficiently. They also need to minimize energy consumption, offer low or no toxicity, maximize safety for the people working with them, and have price points that make them accessible to most businesses. Lastly, the supply chain needs to be able to support demand, and solutions need to offer versatility to support everyone from small family-owned shops to global corporations.  Ensuring these needs mesh cohesively with the megatrends requires striking the best possible balance of all the factors. This is where continual refinement of refrigerant chemistry becomes critical. At Chemours, this process started with the first products in our Opteon™ line of HFO-based stationary refrigerants. Chemours Opteon™ XP products, such as Opteon™ XP40 (R-449A) and Opteon™ XP10 (R-513A), are nonflammable refrigerants offering excellent retrofit solutions for replacing higher-GWP legacy HFCs, such as R-404A, while maintaining an A1 safety listing. ISO Safety Classification of A2L From here, chemists continued to develop ways to further lower GWP and maximize performance, operating efficiency, and energy savings. At Chemours, this resulted in the Opteon™ XL line. Poised to be next-generation refrigerants, these have an ASHRAE and ISO Safety classification of A2L and deliver very low GWP. Due to their low flammability, A2Ls are used in new equipment only. A2Ls can also lower operating costs throughout the life cycle of the equipment In addition to supporting regulatory compliance, A2L performance attributes include increased system efficiency, lower energy consumption, low toxicity, and improved safety for use in a broad range of applications. A2Ls can also lower operating costs throughout the life cycle of the equipment. We're seeing the path to that A2L-centric future take shape. For example, Opteon™ XL41 (R-454B) has already been selected by most pioneering global OEMs, including Carrier, Johnson Controls, and Rheem, which have announced alignment with Chemours for the utilization of this product.  Preparing for the transition Because regulations vary around the world, we find some regions are highly advanced in the transition to HFOs and A2Ls, while others are just getting started or fall somewhere in the middle. Consequently, there is no single plan to prepare for the refrigerant transition. However, the following considerations can help guide what steps you take, and when you take them. Your corporate responsibility mission. The systems you use, sell, or support should be charged with a refrigerant that is in line with your commitment to the health and sustainability of the planet. Your employees. Consider the people working for you. Will pride in working for a green company impact productivity, job satisfaction, and retainment?  Customers and clients. Comfort, safety, being “green and clean”—all come into play in attracting and retaining customers and clients. The age of current systems you service/support. Older HVACR systems have greater potential for refrigerant leaks. In the case of ammonia, a leak can pose fatal health risks, and in the case of HCFCs and HFCs, can result in subpar performance. Older systems also tend to require costly repairs and operate less efficiently. Market awareness. Keep an eye on supply trends and make sure refrigerant supply can meet the needs of the systems you support. Your bottom line. Newer-generation refrigerants and the systems that work with them have been developed to lower energy consumption. Determine when the time is right to make a larger upfront investment in new equipment, which can pay dividends in the form of lower energy bills and overall operating costs. Technician training. A2Ls look, feel, and work like R-410A or R-404A, but there are key differences due to their low flammability. Ensure technicians are properly trained to work with A2Ls as well as their predecessors. In conclusion—collaboration In a world that continues to demand and expect more, the criticality of HFO refrigerants—and, more specifically, next-generation A2L solutions—is undeniable, because of their environmental and performance advantages over existing alternatives. When you think of the role cooling plays in every part of our everyday lives, it’s easy to see how and why what we do as an industry now stands to have a major influence on the future of our planet. From being essential to every step along the cold chain—from farm to fork—to ensuring both comfortable and healthy living environments to providing the cooling that makes the data centers that make modern-day necessities and conveniences possible, refrigerants are a permanent fixture in lives, and will remain so as the world in which we live, work, and play continues to evolve. By collaborating, we can all advance a transition that leads to a healthier, more sustainable planet and opens opportunities for every application in the industry to provide customers and clients with higher-performing, safer, and more sustainable solutions.

The flammability of the new class of low-GWP refrigerants is a source of misunderstanding and unnecessary anxiety among contractors who will be working with the newer materials, which must be used by HVAC equipment manufactured beginning Jan. 1, 2025.   A2L refrigerants The newer A2L refrigerants, specifically R-454B, perform similarly to previously used materials such as R-410A, and flammability is so mild as to be almost negligible. What’s needed is more education to make contractors more comfortable with the newer refrigerants. And sensible precautions, of course.   flammability of refrigerants Among the trainers educating the industry on the benefits of, and needed precautions for, the new materials is Don Gillis, Technical Trainer of Chemours.   “The flammability part of it is the elephant in the room,” says Gillis. “Our training seeks to remove the fear of the unknown and to get ahead of what the expectations are.”  Don Gillis experience At Chemours, he is applying his real-world experience to address the practical aspects of the refrigerant transition Gillis’s background includes more than 32 years of experience in the industry, 24 of which were on a service truck. Before coming to Chemours, he was the Senior Technical Trainer for Copeland compressors where he helped to train thousands of contractors across North America.  At Chemours, he is applying his real-world experience to address the practical aspects of the refrigerant transition in hundreds of training sessions this year.   peculiarities and similarities of new refrigerants “Change is now coming so fast that technicians are struggling to keep up,” says Gillis. “We need more education, not just about the differences in the new refrigerants but also about the similarities. We need to understand the peculiarities and the similarities of new refrigerants compared to what we used in the past.”   Features of A2L refrigerants The refrigerants are safe when handled properly, offer lower toxicity, and have been used effectively around the world Working with A2L refrigerants such as Opteon XL41 (R-454B) is similar to working with R-410A. For R-454B systems, the installation and service procedures are similar. Moreover, the best practices that technicians have used for years remain applicable with A2Ls. These refrigerants are safe when handled properly, offer lower toxicity, and have been used effectively around the world to increase efficiency and reduce emissions.  When working with R-454B, processes that were once described as good practice will be required. These processes include purging a line with nitrogen to remove any residual refrigerant, testing lines under pressure for 60 minutes, and documenting the results.  training sessions Gillis is seeing higher-than-expected attendance at his training sessions this year, with actual attendance sometimes doubling what was expected. There are classes with more than 100 in attendance, even 200 and 300 in some cases. While most of the training is geared toward contractors, distributor training is similar, ensuring that the “counter people” speak the same language as their customers when it comes to the transition.   Urgency due to transition “We are not having an issue of people not coming to training,” says Gillis.  “I think right now there is a new urgency because [the transition] is happening. Dealers and distributors are telling them the new equipment is coming out, and they are peeking in to see what the hubbub is all about. We want everyone to get better. The more knowledge the better.”   R-454B refrigerant availability All equipment manufactured or imported beginning in 2025 will use newer refrigerants New equipment that uses R-454B refrigerant will be on the market within weeks. At least three original equipment manufacturers (OEMs) say they will have equipment out by the end of the first quarter. All equipment manufactured or imported beginning in 2025 will use newer refrigerants.  Misinformation Misinformation is a problem as the refrigerant transition looms, says Gillis. For example, 50 to 60% of attendees at a recent training session were still under the impression that the new refrigerants contain hydrocarbons such as propane. Not true. The flammability of A2L refrigerants more closely resembles the refrigerants currently in use than materials at the far end of the flammability spectrum.  Fact-checking and myth-busting A2L refrigerants have already been used safely for years in automobiles, window air conditioners, PTAC systems, and dehumidifiers.  “I’m all about fact-checking and myth-busting,” says Gillis. “You don’t know what you don’t know.” Some of the misunderstandings may have come from earlier messaging in the industry that addressed A2Ls along with other “flammable refrigerants” such as propane, thus confusing the matter.  Key points Key points Gillis seeks to communicate in his training sessions include:  ∙There are no hydrocarbons or propane in A2L refrigerants.  ∙Although similar to previous refrigerants, an A2L refrigerant cannot be used in an existing unit.   ∙No extra ventilation or placards are required for trucks carrying A2L refrigerants; tanks of Chemours’ Opteon XL41 (R-454B) refrigerant can be transported on their sides.   ∙The 440-pound maximum allowable refrigerant truck load stays in place.  ∙Safety and handling requirements and good installation and service practices are required.  ∙Factors such as servicing, installation, safety, pressure, temperatures, and oils are the same for R-454B as for R-410A.   To access educational resources, contractors and others may visit Opteon.com to request training by webinar, remotely, or in person. There are also YouTube videos available on demand.   training certificate Chemours provides a 2-hour certificate of attendance, with a number enabling “credit” with NATE, ACCA Although there is currently no EPA requirement for special training on the new refrigerants, the jury is out on whether a requirement might be forthcoming. There currently are also no federal or state certifications. Chemours provides a 2-hour certificate of attendance, with a number enabling “credit” with North American Technician Excellence (NATE), Air Conditioning Contractors of America (ACCA), or whomever.   high-GWP refrigerants The U.S. AIM Act will limit the amount of high-GWP refrigerants that can be made in coming years. As the manufacture of legacy refrigerants is phased out over time, existing legacy systems will need to use more reclaimed/recovered refrigerants from existing systems. Fortunately, the processes of reclamation are improving, and even refrigerant mixtures will still have value in the market moving forward. {##Poll1709537519 - What is your preferred format when it comes to training on new aspects of HVAC equipment and installation?##}

AHR Expo 2024 was abuzz with activity, befitting a dynamic industry in the throes of change.  Industry developments such as electrification and the refrigerant transition render business opportunities on the AHR Expo show floor, where exhibitors display a determination to meet the challenges and thrive in the process. Walking from booth to booth during the three-day show in Chicago, I saw the best the HVAC industry has to offer, up close and personal. Innovation and adaptability are the watchwords as the industry journeys into 2024 and beyond. Refrigerant Transition Top of Mind  Patented R-454B refrigerant enables a simpler transition without redesigning equipment The technology transition is well underway for OEMs seeking to meet a pending AIM Act deadline at the end of the year. OEMs are choosing to embrace either R-32 or R454-B refrigerant to replace legacy R-410A, which is being phased out. Patented R-454B refrigerant enables a simpler transition without redesigning equipment, while R-32 offers advantages such as higher capacity, higher efficiency, and easier cradle-to-cradle management. Arkema Arkema is the only producer of R-32 refrigerant in the United States. The newer refrigerant is being embraced as HVAC OEMs seek to meet the deadline of Jan. 1, 2025, to use lower-GWP (global warming potential) refrigerants in their products. The technology transition is just part of the AIM Act implementation that will also limit allocation and require refrigerant management. Chemours Chemours is a manufacturer of R-454A, R-454B, and R-454C refrigerants. At AHR, they presented hourly education sessions on a variety of subjects. The refrigerant transition will impact everyone in the industry, including refrigerant producers, equipment manufacturers, contractors, and end users. R-454B refrigerant provides identical performance in HVAC systems compared to the previous refrigerant (R-410A). There is less need to redesign equipment; just adding sensors for leak mitigation can address the mild flammability of A2L refrigerants. Because of the 2025 deadline, 2024 will be the “year of new products” in the HVAC market. OEMs pioneering Innovation  Carrier and others are offering smaller footprints, seeking to meet environmental targets Innovation in the HVAC market is led by companies such as Carrier, which has introduced 100 new products each year for the past eight years.

The American Innovation and Manufacturing (AIM) Act is among the environmental initiatives and regulations driving the phasedown in the use of hydrofluorocarbon (HFC) refrigerants in the HVAC industry. The AIM Act’s schedule seeks to phase down HFCs by 85% by 2036. The first significant reduction in consumption and production under the AIM Act began on Jan. 1, 2022, representing a 10% reduction from a baseline value. The next major step begins Jan. 1, 2024, with an additional 30% reduction, followed by another 30% reduction starting Jan. 1, 2029. adoption of retrofit or new systems This phasedown, rather than phaseout, approach should prevent any debilitating disruption to the industry; however, the adoption of retrofit or new systems sooner rather than later is key to a smooth transition. “We have a unique opportunity to impact worldwide change, one business, one community at a time by supporting our customers through the phasedown of HFCs,” says Brandon Marshall, Americas Marketing Manager, Stationary and Specialty Applications, The Chemours Company. next-generation products Chemours seeks to help the industry navigate the complex technology and regulatory landscape As the inventor of Freon and Opteon refrigerants, Chemours has been driving evolution in the HVACR industry for nearly a century, innovating next-generation products for diverse needs and applications. As a champion of the HVACR professional, Chemours seeks to help the industry navigate the complex technology and regulatory landscape.  hydrofluoroolefin (HFO) refrigerants Chemours’ Opteon portfolio of hydrofluoroolefin (HFO) refrigerants features zero ozone depletion potential (ODP) and low global warming potential (GWP). The refrigerants offer a balance of performance, environmental sustainability, safety, and cost when considering retrofit or new equipment solutions. Chemours pairs these innovations with technical support, education, and customer service delivered by a team of experts with decades of experience. education and training  “Chemours is highly invested in providing the education and training that will facilitate [the transition], as well as delivering solutions that meet each customer’s unique needs, timeline, and budget,” says Marshall. “The vision of the AIM Act aligns perfectly with our corporate commitment to being the leader in sustainable HVACR solutions and a global force in protecting the environment,” adds Marshall. sustainable, better-performing solutions Chemours’ Opteon portfolio helps customers implement the right solution through the phasedown Chemours’ commitment to “courageous chemistry” drives its development of highly sustainable, better-performing solutions. Chemours’ Opteon portfolio helps customers define and implement the right solution through the phasedown. Many systems are still operating with R-22, although the supply is now limited to the reclaimed refrigerant. Due to dwindling supply, these users urgently need to retrofit their systems. The next phasedown under the AIM Act is coming quickly on Jan. 1, 2024.  Market price availability and impact For several years, Chemours has seen commitments from major OEMs to produce equipment operating with HFOs. Marshall says that continued HFC phasedowns, OEM adoption, and increased manufacturing of HFO refrigerants by companies like Chemours will impact market pricing and availability for HFOs and HFCs.  The industry can expect an exponential increase in retrofits and new installations of HFO-charged equipment. R-454B Chemours Opteon XL41 was the “big product” the company emphasized at the AHR Expo in February. The R-454B refrigerant is the new-generation solution paving the way for what lies ahead in the short- and long-term regulatory landscape. It is the lowest-GWP replacement for R-410A on the market offering a 78% reduction in GWP while providing value and peace of mind as the industry transitions away from HFCs, says Chemours. Opteon XL41 The more people we can introduce to Opteon XL41 and the stronger our collaborations, the greater the impact" Opteon XL41 has been selected by leading global OEMs, including Carrier, Johnson Controls, and Rheem, which have announced alignment with Chemours for the utilization of this product. “All of us realize that the more people we can introduce to Opteon XL41 and the stronger our collaborations, the greater the impact we can have in meeting environmental objectives,” says Marshall. commercial refrigeration sector The commercial refrigeration sector is quickly following air conditioning by embracing next-generation products such as Opteon XL10 (R-1234yf/ AR4 GWP 4), Opteon XL20 (R-454C/ AR4 GWP 148), and Opteon XL40 (R-454A/ AR4 GWP 239). “However, many businesses operating refrigeration systems need to walk before they run,” says Marshall. “Not everyone can immediately invest the money and/or time for new installations.” OEMs OEMs are supporting the transition by ensuring a healthy supply of retrofit equipment is available while keeping close tabs on the demand for new equipment charged with next-generation products. Several high-performance, efficient, and environmentally sound retrofit solutions exist utilizing HFO refrigerants such as Opteon XP10 (R-513A/ AR4 GWP 631) and XP40 (R-449A/ AR4 GWP 1397).  Leveraging resources  Ultimately, everyone must appreciate the value of A2Ls and be comfortable using them “By remaining data-driven, suppliers in the industry will be ready to meet changing demands and support the health of businesses and the planet,” says Marshall. Ultimately, everyone must appreciate the value of A2Ls and be comfortable using them. This requires ongoing education and training. There are many opportunities for this already out there, so technicians and the industry need to start or continue to leverage these resources, says Marshall.  webinars Chemours offers a variety of training to ensure the safe use of A2Ls and encourage adoption as soon as it is practical. This includes webinars with several industry partners and leaders, on-site training, online training brochures, videos, and customer support to ensure everyone is prepared for the transition. best practices Fortunately, the use of A2Ls does not amount to a situation of “back to square one” that requires technicians and installers to relearn everything while maintaining current skills to continue to service older systems. In reality, A2Ls such as Opteon XL41 (R-454B) feel very similar to working with R-410A. For R-454B systems, the installation and service procedures are similar to those of R-410A.  Moreover, the best practices that technicians have used for years remain applicable with A2Ls. These refrigerants are safe when handled properly, offer lower toxicity, and have been used effectively around the world to increase efficiency and reduce emissions, says Marshall. Environmentally responsible operations Environmentally responsible operations are a reality that will continue and escalate" “The world is locked into driving towards a more sustainable planet,” says Marshall. “Environmentally responsible operations are a reality that will continue and escalate." "This is driven not only by the regulatory landscape but also by corporate responsibility missions. The businesses that thrive will support these missions at every level of their operations.” sustainability  As the phasedown continues and receives more attention, consumers will join the conversation, driving everyone from contractors to facility managers to show support for environmental sustainability. Marshall says the installers and technicians need to be prepared to service these HFO-driven systems otherwise, that business will “walk out your door.” Regulatory compliance “Regulatory compliance may be the strongest motivator for change currently, but in our industry, every player must work to reduce the overall consumption of higher-GWP products,” says Marshall. “It is our responsibility to the communities we serve.” Chemours is a global chemistry company with leading positions in titanium technologies, thermal and specialized solutions, advanced performance materials, and chemical solutions, all working to create a better world through the power of our chemistry, according to the company.

Johnston County Public Schools, located in Smithfield, North Carolina, chose Carrier to improve energy efficiency and comfort at five schools. Carrier is a part of Carrier Global Corporation, a global pioneer in intelligent climate and energy solutions. AquaSnap® 30RB Johnston County Public Schools (JCPS), located in one of the nation’s fastest-growing counties, is the seventh-largest school district in the state. JCPS used money from the U.S. Department of Education’s Elementary and Secondary School Emergency Relief (ESSER) Fund to replace a dozen chillers. The school district selected Carrier’s AquaSnap® 30RB, an air-cooled liquid chiller offering an effective all-in-one package that is easy to install and maintain. New Equipment Replaced Old Chillers The schools are in North Carolina’s fastest-growing county with 5,000 students enrolled at the five schools The new equipment replaced chillers that were between 20 and 25 years old at Cleveland Elementary, West Clayton Elementary, and Clayton High in Clayton; McGee’s Crossroads Elementary in Angier; and Glendale-Kenly Elementary in Kenly. According to the latest census data, the schools are in North Carolina’s fastest-growing county with 5,000 students enrolled at the five schools and are part of a larger school system with more than 37,000 students in 48 schools.

The well-known Italian brand, Big Mamma Restaurant Group, has recently transformed an old four story bank into a striking new restaurant, Jacuzzi, in the heart of High Street Kensington, West London, United Kingdom (UK). In keeping with the grand design of this new ‘pleasure palazzo’, the interior environment needed to offer ultimate comfort and to help create a memorable and luxurious dining experience. Summit Design specified, designed and installed the comprehensive new heating and cooling system, utilizing two 45kW Panasonic 3-pipe ECOi EX MF3 units with nanoe X technology. Panasonic 3-pipe ECOi EX MF3 units installed The Big Mamma Group selected the abandoned old bank building on Kensington High Street The Big Mamma Group selected the abandoned old bank building on Kensington High Street, for its fourth restaurant in London – Jacuzzi, a luxurious 170-seat Italian dining experience. Be-decked with high end Italian treasures and decadent interior design, the site covers four floors, including a Sicilian mezzanine floor with a retractable roof opening out to the bustle of High Street Kensington. Transforming the old historic bank building to a fully functional and fit for purpose restaurant required extensive renovations, including an entirely new heating, cooling and hot water system. To service the 4,000 sq. ft building, Jacuzzi needed a high-capacity performance and energy efficient solution, providing heating and cooling with accurate climate control and ultimate comfort.  Panasonic 45kW 3-pipe ECOi EX MF3 series With Summit Design’s in-depth understanding and knowledge of heating and cooling, the company specified two Panasonic 45kW 3-pipe ECOi EX MF3 series with nanoe X and with a range of indoor units including adaptive ducted, 4-way cassettes, ceiling suspended, floor mounted, wall mounted and slim ducted units. “The Panasonic ECOi EX series is one of the most advanced VRF systems currently on the market, offering not only high performance for simultaneous heating and cooling but also sophisticated installation,” says Dan Sparling of Summit Designs, adding “The solution is ideal for commercial applications having enough capacity to run the energy efficient system for the entire building.” Dan Sparling adds, “Furthermore, the wide selection of indoor units that the Panasonic range offers meant that we could adapt the system design to select the best and most appropriate indoor units, ensuring best choice for each space. It was very important for the heating, cooling and ventilation system to blend seamlessly into the interior design, so as to not distract in any away from the impressive diner experience and general ambience of this high-end restaurant.” Powerful performance for both heating and cooling The Panasonic ECOi EX MF3 offers powerful performance for both heating and cooling The Panasonic ECOi EX MF3 offers powerful performance for both heating and cooling. Designed with a twin rotary inverter compressor, the system is highly energy efficient even in extreme ambient temperatures of say 43 degree C and continue to cool, even when the outside temperature reaches a maximum of 52 degree C, with a high SEER of 3.49 and SCOP of 4.17. The optimized energy consumption was enhanced by the addition of the heat recovery box, which was able to connect multiple indoor units with a single box. The heat exchanger captures the waste heat from the cooling operation and is able to redirect it using the 3-pipe system to areas requiring heating. This capability allows the system to heat and cool multiple areas simultaneously, allowing for greater independent climate control across the four floors and flexibility in meeting a comfortable climate for all. Panasonic system offers flexibility The installation at the large Jacuzzi property was made easier by the flexibility of the Panasonic system. The units provide up to 1000 m of piping and up to 30 m height difference between the indoor units, meaning the system was able to extend its reach across all four floors with ease. The ECOi EX MF3 system provides easy to use and effective temperature and humidity controls, has a newly designed fan for optimized airflow, and customizable settings that can be tailored to suit the needs of the building. Panasonic ECOi units come as standard with nanoe X The Panasonic ECOi units now all come as standard with nanoe X technology" “The Panasonic ECOi units now all come as standard with nanoe X technology, a great benefit that really adds value, especially to a luxury dining experience like the new Jacuzzi restaurant,” said Rachel Wales, Regional Sales Manager for Panasonic. Rachel Wales adds, “The nanoe X technology inhibits the growth of harmful bacteria, viruses, and other airborne pollutants. With nanoe X, the system can reduce unpleasant odors, tackle mold and allergens and even help keep hard and soft surfaces clean, all of which culminate in creating a better indoor air quality and enhancing the experience for staff and guests alike.” Quick and convenient installation The Panasonic system was able to be installed quickly without any problems, helping deliver the opening of the new restaurant on time. Dan Sparling stated, “We are so pleased with the operation of the system so far and are assured that staff and guests of the restaurant are kept comfortable throughout their experience.”

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.

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.
