Each day we’re reading headlines about decarbonization ambitions for buildings while challenged with supporting day-to-day operational needs. Yet, we’re still tasked with delivering energy and cost reductions. Given the magnitude of energy consumption and the importance to occupant/tenant comfort, HVAC systems warrant significant attention. There are a lot of options with new equipment and controls to drive energy use down and enhance overall comfort that are very impactful, when budgets allow. However, there are budget friendly options that should be considered now. There are aftermarket products that restore lost performance efficiency, reduce loads on equipment and extend equipment life.  A challenge is knowing which products really work and what can be trusted. Refrigerant additives have been around for decades, solving several issues including improved thermal heat transfer, reduced frictional forces through enhanced lubrication, acid scavengers, water displacement, stop leaks, and the list goes on. Over forty years ago, some of the first refrigerant treatments were formulated, with varied results. The principal objective was twofold: enhance the heat transfer from the refrigerant to the heat exchanger coils and reduce friction on the compressor moving parts.  How to reduce compressor friction and keep it low Industry offered improvements to refrigerant oils, building on synthetic oil development HVAC systems include oil to lubricate the compressor mechanical moving parts with mineral oil being the old standard, used for decades. Older systems with R-22 refrigerant, as well as other types, use mineral oil.  This oil, made from naturally occurring crude petroleum oil, is prone to breakdown over time from wear and elevated temperatures. This means hermetically sealed compressors operating with the same oil as when originally built are running with greatly diminished friction protection. Friction protection longevity was greatly improved with the advent of synthetic oils, but even these oils can see diminished protection from wear and elevated temperatures. Industry offered improvements to refrigerant oils, building on synthetic oil development. Two additives commonly found in gear oils include active sulfur with phosphorus, noted as Extreme Pressure (EP) gear oils. This same approach found its way to HVAC systems, adding materials that offered greatly improved friction reduction. Some mistakes were made, such as using polytetrafluoroethylene (PTFE), best known as Teflon. Although PTFE has phenomenal lubricating properties, it is too large of a minimum particle size, creating havoc within expansion valves. Teflon also received scrutiny by researchers identifying adverse health effects. Today, there are several technologies promoting improved refrigerant lubricants, either as a direct replacement or as an additive to existing oils. How to restore lost HVAC performance efficiency The refrigerant oils that keep compressor moving parts running serves a second important role: acting as a seal to keep compressed refrigerant from escaping from the compressor and ending up in the oil sump. HVAC engineers allow and design for some oil to migrate through the refrigerant loop, the condenser and evaporator coils. More sophisticated equipment, such as chillers, have features to collect and return most of this oil. Simpler systems rely on the high velocity of the refrigerant to pull the oil through the coils and return it to the compressor. Inevitably, some oil remains as a film on the heat exchanger coils and slowly builds through the operational life of the equipment. The oil buildup continues to reduce the heat transfer efficiency between the refrigerant and the coil walls. There have been numerous formulations brought to the market with few detailed accounts of chemistry specifics An opportunity was born for creative individuals to invent formulations that would remove this efficiency robbing oil layer. Early design attempts sometimes led to more problems than the efficiency improvements were worth. Some chemistry mistakes included using solvents or other cleaning agents to aid in removing oil from heat exchanger tubing. This diminished the effectiveness of the refrigerant oil and led to shortened equipment lives. There have been numerous formulations brought to the market over the past four decades with few detailed accounts of chemistry specifics. There are few patents in addition to product website information that offer limited details in the public domain, making it hard to trust the suppliers. Today’s formulations offer greater opportunity for realized performance gains, especially given advances in material science. Nanomaterials have enabled several newer solutions to be developed. One such product employs graphene, which is known for its fantastic heat transfer and lubricating properties. Nanomaterials offer properties to enhance heat transfer, improve lubrication while negating concerns about excessive buildup within expansion valves. For example, graphene exists as a one atom thick nanomaterial. Perhaps the biggest challenge to the use of nanomaterials was how to keep the particles in suspension over the life of equipment, something that most specialty chemical houses hold as trade secrets.  Some products offered today boost refrigerant performance, stating altered boiling points. The performance is achieved by adding particulate that acts as nucleating sites. As material science continues to advance, we’ll see more products enter the market that also address changes in the choice of refrigerants and refrigerant oils. How to select the best additive for your needs Make sure the formulation is compatible with your specific equipment, refrigerant and refrigerant oil When considering additives to reduce energy consumption for your HVAC refrigerant systems, your contribution to decarbonization, do your own due diligence and require validated performance efficiency improvements.  Make sure the formulation is compatible with your specific equipment, refrigerant and refrigerant oil. Given that many sales agents won’t divulge their respective chemistry (or don’t know it) and most individuals responsible for HVAC equipment aren’t chemists, look for credentialed validations and testing. Ensure the products have been evaluated against ANSI standard compatibility tests and performance validated to ASHRAE or other accepted industry standards.  What the market thinks of refrigerant additives Over the first few decades since the creation of efficiency improving formulations for refrigerants and refrigerant oils, there has been mixed market adoption. The early days of failed attempts with oil degrading use of solvents or the use of expansion valve clogging solids, left a lingering perception of “snake oil”. Only those businesses that took the time to sort through the offerings to find the truly validated products found success in reducing their HVAC energy use and an added benefit of extending the life of their equipment. Today the market is better accepting of newer technologies, gaining distance to the old wild west days of unproven formulations.  Trust is being earned for those businesses that offer professionally validated products that stand behind them with warranties.

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.

Gradient seeks to bring the benefits of mini-split systems - variable speed drive, efficient operation, heat pump heating - to a wider audience, by simplifying the installation process. Gradient offers a design that is installed in a window, but it has more similarities to mini-split systems than to a window air conditioner. simple installation The system is designed for simple installation by a layman – it generally takes about 15 minutes. Using heat pump technology, Gradient has the efficiency and power of professionally installed products, with similar features, at a lower price point. Our product is installed through a window, but still allows users to open and close the window" “Historically, a mini-split has not been feasible for every situation,” said Vince Romanin, the Chief Executive Officer (CEO) of Gradient (formerly Treau), adding “They need to be professionally installed, which can be expensive.” He further stated, “They also are not an option for renters or buildings that are not retrofitted. Our product is installed through a window, but still allows users to open and close the window and get natural light.” Gradient unit featuring modular design The Gradient unit resembles a bench with two thick supports that hang over a windowsill. The modular design places the power and noise outside the window. It may look like an ultra-modern window unit, but it provides more than cooling. The system’s heat pump can be used all year round, as a heating system for homes in moderate climates (where the temperature is usually 46°F or higher), and to supplement a main heat source in colder climates. Focus on full building electrification Vince Romanin adds, “Our focus is on full building electrification. This product is an important stepping stone toward our long-term roadmap of cold climate heat pumps that enable the removal of fossil fuels in heating buildings.” Gradient seeks to address the environmental impact of current HVAC systems. Forty-eight percent of all energy consumption in American homes is a result of cooling and heating. HVAC is a major contributor to climate change, due to the refrigerants they use and their use of fossil fuels. As the climate changes, the need for heating and cooling systems increases, thereby creating a vicious cycle. Advanced heat pump technology Gradient breaks the cycle with products that allow you to be cool and comfortable without heating the planet" “Gradient breaks the cycle with products that allow you to be cool and comfortable without heating the planet, using heat pump technology and a climate-friendly refrigerant,” said Vince Romanin, adding “It is engineered to be easy-to-install and easy-to-use from anywhere, thanks to a mobile app.” “HVAC installers currently require extra time and equipment to install traditional mini-splits. The Gradient system is faster and cheaper because it is self-installed,” explains Vince Romanin, adding “The long-term impact of this additional option for consumers can help installers serve more customers in less time and at lower costs.” Heat pump/air conditioner using climate-friendly refrigerants HVAC, in general, is a major contributor to climate change, due to the refrigerants that they use and also contributed to their use of fossil fuels. Current heating and cooling systems release about 9 Gigatons tons of carbon dioxide equivalents each year, which is around 20% of all emissions and more than the entire transportation sector. Gradient offers a heat pump/air conditioner that uses climate-friendly refrigerants, thus reducing heating and cooling emissions by up to 75% today, and by 99% in the next few years. The system is also attractive and easy to use. Gradient expects the system to emit 75% less direct and indirect carbon emissions than today’s systems. This is based on using more environmentally friendly refrigerants, being more efficient, and displacing fossil fuel heating with electric heat pump heating. Fully decarbonized heating and cooling system Vince Romanin said, “Our end goal is a fully decarbonized heating and cooling system, which we expect to get to, by continuing to push for more environmentally friendly refrigerants, pushing our heating capability into colder climates, and building demand response into our system, so that it can work better with grid renewables.” High interest in the new product is testament to the power of sustainability as a marketing feature" “High interest in the new product is testament to the power of sustainability as a marketing feature,” comments Vince Romanin, adding “We believe that good business and carbon reduction are not mutually exclusive. In the long term, creating a better environment in which to live is the best way to create the best environment for doing business.” There are also uses in commercial and multi-unit housing applications. The company is already in conversation with several commercial customers, ranging from multi-unit housing, hotels, and schools among others. Large commercial buildings in New York City will be required to meet new energy efficiency and greenhouse gas emissions limits by 2024. Solution to mitigate Costs of changing building infrastructure Gradient offers a solution to mitigate the costs of changing major building infrastructure, to in order accommodate new HVAC systems. The system does not require an electrical upgrade or new ductwork, and installation does not damage the exterior of the building. Currently, Gradient is available for pre-order across the United States of America (USA), with deliveries beginning from July 1, 2022. The company envisions expanding to additional markets in the future.

The story of Bluon is the tale of how a chemical company blended a new refrigerant, and then later evolved into a large, brand-agnostic online community that helps technicians do their job. Currently, Bluon is on the verge of monetizing its platform, linking e-commerce into its vast wellspring of technical information to guide HVAC installers.  Tdx 20 refrigerant blend Bluon created and received EPA approval for its Tdx 20 refrigerant blend (R-458A) to replace R-22 and provide 20% greater efficiency. The new blend was well accepted in the market, but technicians were a roadblock, faced with a need to retrofit the new formulation into hundreds of thousands of units in the field. To address the problem, Bluon created a smartphone app providing retrofit instructions for each unit on how to make the transition. Adding features to the app XREF allows the identification of appropriate replacement parts that are compatible with a certain HVAC unit As more technicians started using the app, it took on a life of its own. In response, Bluon added new features and functionality to help technicians every day. Then Bluon acquired the XREF Publishing Company and incorporated the company’s replacement and cross-referenced part information into the platform. XREF allows the identification of appropriate replacement parts that are compatible with a certain HVAC unit. After the acquisition, Bluon incorporated XREF’s massive database of HVAC 300,000 Models including original parts lists directly into the hands of technicians on its installer app. Additionally, Bluon included the cross reference capability into its overall platform to benefit local distributors who will soon be able to use the valuable data when answering order requests coming into Bluon Member technicians on the installer app. BluonLive Recently, Bluon completed its Series B with $37 million in financing, which is enabling them to develop an e-commerce platform (BluonLive), the final link that makes the app even more valuable to HVAC installers. (The refrigerant business still provides $12-15 million in annual revenue.) “We are the only global platform that has gotten self-adopted at scale by technicians,” says Bluon CEO Peter Capuciati. The app currently has 104,000 members, roughly 30% of the 320,000 technicians in the United States, who had previously tended not to use mobile apps. Capuciati says Bluon built the app in a user-friendly, “likable” way, which explains the large audience of “sticky” users. It also provides a high level of technical support for the industry. Launch of the app The app will transform how technicians buy parts and equipment for a job site “We woke up one day and had this large community of HVAC technicians,” adds Capuciati. “So how do you monetize it without adding costs for the technician?” When the e-commerce platform launches in May or June 2022, the app will transform how technicians buy parts and equipment for a job site. Historically, technicians often didn’t know what they needed to buy until they visited a local distributor, which had the required information about which replacement parts are suitable, cross-reference by part number with the various alternatives. Now that information is part of the Bluon platform to benefit the HVAC technician in the field. Distributors Working on the app Distributors who join the Bluon Network get access to what Bluon is calling BluonLive – a portal allowing them receive order requests generated from technicians in the field using the Bluon app. BluonLive covers both “direct replacement” parts, typically the same part but white-labeled by another company; and “substantial replacements,” which may need a different wiring harness, be positioned differently, etc. Notes about how substantial replacements can be made compatible are included for the distributor to see. “We help the industry across the board,” says Capuciati. “The techs on our platform get more work done; they are more productive.” More efficient technicians can help offset the shortage of technicians in the U.S. market. Less training required Distributors with BluonLive will inform the technicians exactly what part he or she needs at what cost Each year, an estimated two technicians retire from the workforce for every recruit to the industry.  The app can also provide information to help guide less experienced technicians and lessen the need for training.  Now the process of choosing the right part can be a true e-commerce experience. Distributors with BluonLive will inform the technicians with the Bluon mobile app exactly what part he or she needs at what cost. They can buy the part on the app directly from their local distributor. Convenience The local distributor still gets the business, and the technician gets the added convenience. The app can also help wholesalers, who have a shortage of counter staff and face the imminent retirement of many employees who have the most instinct and product knowledge. The expression is that “behind every great tech is great counter staffs.” Bluon effectively scales this expression and allows the required institutional knowledge to flow to any technician’s fingertips. Brick-and-mortar distribution Bluon expects to launch their e-commerce platform this June,  with up to 2,000 stores of the roughly 6,000 brick-and-mortar distribution facilities in the United States initially signed up. In this way, they will enable and enhance the supply chain at the local level, connect techs to local distributors, and keep the local wholesaler central to the HVAC industry. And to monetize the app, Bluon will collect a small fee from the distributor for each transaction that happens between the local technician using the app and the local distributor.

Wren is a climate subscription service that helps individuals offset their carbon footprint through monthly contributions. Users can calculate their carbon emissions using Wren’s intuitive calculator and fund various climate projects, including refrigerant destruction. Wren emphasizes transparency by providing regular updates on the impact of contributions, including data, photos, and stories. The platform aims to make climate action simple and effective, ensuring that every dollar contributes to meaningful environmental change.  About A-Gas  A‑Gas is a world pioneer in the supply and lifecycle management of refrigerants and associated products and services. Through the first-class recovery, reclamation, and repurposing processes, we capture refrigerants and fire protection gases for future re-use or safe destruction, preventing harmful release into the atmosphere. For over 30 years, A-Gas has supported clients and partners on their environmental journey by supplying lower global warming gases and actively increasing the circularity of the industries we serve, building a sustainable future.   Challenge  HCFC-22 is a potent greenhouse gas with a global warming potential (GWP) much higher than CO2 The widespread use of refrigerants like HCFC-22 (R22) presents a significant environmental challenge. HCFC-22 is a potent greenhouse gas with a global warming potential (GWP) much higher than CO2 (one molecule of R22 has a global warming impact 1,810 times that of one molecule of CO2). If not properly managed, its release would have a negative impact on the atmosphere. As these refrigerants reach the end of their lifecycle, there is an urgent need for effective solutions to prevent their emissions and minimize their environmental impact.   Solution  To address this challenge, A-Gas recovers refrigerants for reclamation or destruction at A-Gas facilities across the country. By leveraging Wren's platform to mobilize individual contributions and A-Gas' technical expertise in lifecycle refrigerant management, this partnership enabled an environmentally conscious solution for the used refrigerant. It underscores the potential for innovative partnerships that can help to further reduce emissions in the refrigerant industry through its on-site refrigerant recovery service (Rapid Recovery®), refrigerant buyback programs, and wholesale supplier reclaim program (Refri-Claim™). HCFC-22 destruction project The ACR methodology has included HCFC-22 as eligible for destruction-generated offsets since 2017 Wren and A-Gas formed a partnership to provide Wren subscribers with the opportunity to fund an HCFC-22 destruction project through the generation of A-Gas carbon credits to ensure the gas does not escape into the atmosphere. While the ACR (formerly American Carbon Registry) methodology has included HCFC-22 as eligible for destruction-generated offsets since 2017, few have completed such projects because the price of HCFC-22 is so high; it is more profitable for organizations to reclaim this product.  ACR’s methodology As such, this is one of the first HCFC-22 destruction projects utilizing ACR’s methodology. Approved by the International Civil Aviation Organization (ICAO) to provide carbon credits in its Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA), ACR is highly regarded across the world.  Results  The partnership yielded multiple environmental benefits:   Emissions Avoided: The initiative successfully avoided the release of 16,000 tons of CO2-equivalent emissions by destroying HCFC-22. This substantial elimination of greenhouse gas emissions demonstrates the effectiveness of the program.   Subscriber Engagement: Wren provided its subscribers with detailed updates on the impact of their contributions. These updates included data on the quantities of HCFC-22 destroyed and the corresponding emissions reductions. This transparency helped build trust and encouraged ongoing participation in climate action.   Educational Impact: The collaboration raised awareness about the importance of proper lifecycle refrigerant management. Wren and A-Gas educated the public on lesser-known aspects of climate change mitigation by highlighting the environmental benefits of destroying high-GWP substances.   Conclusion  This partnership enabled an environmentally conscious solution for the used refrigerant By leveraging Wren's platform to mobilize individual contributions and A-Gas' technical expertise in lifecycle refrigerant management, this partnership enabled an environmentally conscious solution for the used refrigerant. It underscores the potential for innovative partnerships that can help to further reduce emissions in the refrigerant industry.  refrigerant destruction protocols and technology "We are excited to work with A-Gas to push forward the standard of refrigerant destruction protocols and technology," said Landon Brand, CEO, of Wren. Landon Brand adds, "This is one of the most reliable and impactful project types we have found in our years of funding climate solutions, and we hope our community can keep blazing a trail to eliminate these dangerous refrigerants."

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. For the past several years, Chemours, ARS, and Hensley have worked together to retrofit the distributor’s existing R-22 and R-404A systems to Opteon™ XP40 (R-449A), a hydrofluoroolefin (HFO) blend offering zero ozone depletion potential (ODP) and a significantly lower global warming potential (GWP) than legacy products. Phasedown of HFC refrigerants Hensley Beverage is proud to partner with Chemours, TBSI, and ARS to help develop innovative solutions" However, with the ongoing phasedown of HFC refrigerants under the U.S. EPA’s American Innovation and Manufacturing Act (AIM), the teams began weighing the benefits of an even bolder upgrade.  “Hensley Beverage is proud to partner with Chemours, TBSI, and ARS to help develop innovative solutions and responsible business practices that drive sustainability in our community," said Alex Dunn, SVP of Operations, Hensley Beverage. Partnership and collaboration Alex Dunn adds, "These groundbreaking results are a culmination of partnership and collaboration. It is refreshing to work with three organizations that are this passionate about developing pioneering products that will help shape a better future for the communities we serve.” Solution  A mildly flammable refrigerant with an ASHRAE A2L safety classification, Opteon™ XL20 is designed for use in new equipment Even as Chemours, ARS, and Hensley continued to employ retrofit solutions in some areas strategically, they explored options that would put the company in a stronger position for the long term. Chemours recommended bringing Opteon™ XL20 (R-454C) into Hensley’s refrigeration plan. A mildly flammable refrigerant with an ASHRAE A2L safety classification, Opteon™ XL20 is designed for use in new equipment, so Hensley identified an old R-22 system near the end of its life that was ideal for replacement by a new system using Opteon™.  Opteon™ XL20 Opteon™ XL20 has been used for several years in Europe and is expected to become the new norm in the U.S. by 2026, based on the current direction provided by the EPA. Leveraging its experience in Europe, the Chemours team of technical service and business development resources is prepared to support end users as they consider trial installations using A2L refrigerants.  Opteon™ XL20 - The future of sustainable low- and medium-temperature refrigeration: GWP of 148 (a 96% reduction versus R-404A).

Chemours was ready with our next-generationOpteon™ XL20, which will ensure they achieve maximum performance, operating efficiency, and sustainability." servicing and Installation Heatcraft and Copeland had the knowledge and experience of emerging A2L requirements The installation brought together additional resources from the HVACR industry, including Copeland and Heatcraft Refrigeration Products, two ARS manufacturing partners as well as Technical Building Services, Inc. (TBSI), the local HVAC service provider. As global HVACR technology pioneers helping customers achieve their sustainability, decarbonization, and regulatory compliance goals, Heatcraft and Copeland had the knowledge and experience of emerging A2L requirements and the capabilities to support the project. TBSI was selected as the contractor for installation and servicing. Time- and cost-efficient With the team assembled, Chemours took the head on the project, ensuring that the contractor, Hensley’s service personnel, and others involved were certified through the ESCO Institute’s A2L refrigerant training program, and answering any questions from the local authorities.  After safely recovering the R-22 for use in other Hensley systems, the team from TBSI started removing the existing Keg 6 equipment, hanging new evaporator coils, and running new refrigerant lines. Installation, evacuation, and charging procedures were very similar to the current refrigerants in use by industry, making for a time- and cost-efficient process. Climate technology Copeland has always been focused on not just setting the standard in climate solutions" “Copeland has always been focused on not just setting the standard in climate solutions with pioneering brands in compression, controls, software, and monitoring, but pioneering the evolution in this space. Our role in the system design and installation for Hensley was right in our wheelhouse," said Brian Schroeder, Engineering Manager, Refrigerants, Copeland. Brian Schroeder adds, "What we accomplished together demonstrates that by bringing together energy-efficient products,regulation-ready solutions, and expertise, we can revolutionize the next generation of climate technology for the better.” R-454C refrigerant “Our tools and gauges were already enabled for the R-454C refrigerant. The startup and charging of both systems went pretty smoothly," said Sergio Pelayo, Vice President of TBSI. Sergio Pelayo adds, "TBSI is proud to have participated in the project at Hensley and, by doing so, added to the variety of equipment we’ve worked on since founding our business in 1990. This was a great opportunity to grow our experience with A2Ls.” Copeland monitoring data  Copeland applied monitoring units to the systems that capture nearly two dozen data points every second To make sure the system performed as expected, Copeland applied monitoring units to the systems that capture nearly two dozen data points every second. The data has shown that the systems are running as designed. “We are thrilled with the results of the R-454C project with Hensley Beverage," said Bob Landi, Vice President and General Manager of Heatcraft Refrigeration Products. Bob Landi adds, "As we continue our journey toward new regulation compliance, this successful collaboration has been instrumental in leveraging Heatcraft’s new product design efforts, with A2L refrigerants being an important part of the mix. We are poised to head the industry and provide more customers like Hensley with cutting-edge solutions that drive their success.” Summary Influenced by upcoming regulatory changes and stronger organizational ESG commitments, the commercial refrigeration industry’s transition to lower GWP refrigerants is inevitable. Opteon™ refrigerants provide organizations with lower GWP options that can help extend the useful life of their systems, as well as new equipment options that enable decades of reliable operation. Moreover, these systems answer the consumer preference for businesses that utilize responsibly manufactured products and support a greener environment.  Hensley’s approach Hensley’s approach demonstrates an ideal way for companies to meet the needs of refrigerating their products while following the guidelines of the HFC phasedown. It’s important to assess where equipment is in its lifecycle and determine if it makes the most sense in terms of budget, performance needs, and corporate vision to 1) retrofit existing equipment for more efficient and sustainable operation or 2) replace it with A2L refrigerant technologies and products.

The 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.

High-performance Toshiba heating and cooling equipment has been used in combination with a solar photovoltaic (PV) and battery storage system as part of a project to help future-proof a five-bedroom home in Cheshire. Toshiba Carrier UK Ltd (TCUK) is part of Carrier Global Corporation, the global provider of healthy, safe, sustainable, and intelligent building and cold chain solutions. Toshiba ESTIA air-to-water heat pumps Two 11kW Toshiba ESTIA air-to-water heat pumps operating on lower global warming potential (GWP) refrigerant R-32 were installed at the 5,500ft2 property, alongside two Toshiba MiNi VRF systems. The Toshiba solution replaced an inefficient heating system and is supported by a 16kW solar PV installation plus 11kW of battery storage and measures including triple-glazing. Energy-neutral outdoor and indoor units  Homeowner and renewables consultant - Dave Meseck says the property is “energy-neutral” during the summer months, with generated and stored energy offsetting electricity consumed from the grid.  One of the ESTIA systems serves around 90m2 of underfloor heating in the open-plan kitchen and dining area, while the other provides hot water and heats the upstairs radiators and towel rails from a supplied 300-liter cylinder. The ESTIA indoor units include a 3kW backup heater to ensure continuity of operation at extremely low ambient air temperatures. Toshiba Mini SMMSe VRF The 5hp system provides heating and cooling for the room above a triple garage via a 5.6kW four-way cassette A 6hp (15.5kW) Toshiba Mini SMMSe VRF is connected to ducted units in the bedrooms and two of the newly designed compact 3.6kW one-way cassettes downstairs, which have been designed to fit between the joists on a traditional home. The second 5hp (14kW) system provides heating and cooling for the room above a triple garage via a 5.6kW Toshiba four-way cassette, while the garage space below, where a spa area is planned, is served by two wall-mounted units. Efficiency “The whole system has been running since December last year and the way it has transformed the house is fantastic,’’ said David Meseck, a Specialist in renewables, sustainability, and the circular economy. He adds, “It was important to get everything right; the project was sized correctly and the equipment installed properly." Cost-effective all-electric heating system As well as helping to future-proof our home and reducing energy costs, the changes have added value to the property" David Meseck continues, "Together with the other measures, we now have an efficient, all-electric heating system with the added benefit of cooling in summer, and the annual servicing cost is comparable to boiler cover. As well as helping to future-proof our home and reducing energy costs, the changes have added value to the property." He adds, "I would urge anyone looking to invest in their home to look at the bigger picture and make it an environmentally-responsible investment.’’ Four models are available in the ESTIA range, spanning capacities from 4-11kW, all with reversible operation to provide cooling as well as heating if required. twin rotary compressor At the heart of ESTIA is Toshiba's award-winning twin rotary compressor, which contributes to the system's outstanding energy efficiency rating of A+++. The compressor enables the heat pump to continue supplying hot water even during exceptionally cold weather, delivering water at 62 degrees C when outdoor temperatures fall to -25 degrees C. ESTIA can also continue producing DHW at exceptionally high outdoor temperatures (43 degrees C) to deliver maximum running cost savings. all-in-one floor-standing hydro-module Toshiba offers a space-saving wall-mounted hydro-module for boiler replacement projects such as this, with a choice of 150l, 200l, or 300l capacity external cylinders. For new-build projects, an all-in-one floor-standing hydro-module with an integrated 210l tank provides a compact solution for both heating and DHW storage. Easy-to-install ESTIA provides a superb solution for homeowners or small businesses looking to replace less efficient systems" “ESTIA provides a superb solution for homeowners or small businesses looking to replace less efficient systems," said David McSherry, David McSherry, Head of Sales for Toshiba Air Conditioning UK, Carrier Global Comfort Solutions Europe. “It is quick and easy to install on-site, and Toshiba’s renowned reliability means a long working life, backed by our excellent warranty.” Performance, warranty, and reliability Installer - Peter Franks, Managing Director of Mansfield-based Woburn Mechanical Services Ltd, added, “This is by some distance the biggest domestic project we have undertaken. The customer knew exactly what he wanted and now has a comprehensive heating and cooling system." Peter Franks concludes, "The Toshiba equipment is excellent in terms of performance and reliability and comes with a seven-year warranty. We wouldn’t be fitting it if we didn’t have complete confidence in it.’’
