Carrier confirms its refrigerant strategy in Europe by choosing HFO refrigerants with low Global Warming Potential (GWP) for most of its commercial heating, ventilating and air conditioning (HVAC) product applications. Carrier, a world leader in high-technology heating, air-conditioning and refrigeration solutions, is a part of Carrier, a leading global provider of innovative HVAC, refrigeration, fire, security and building automation technologies. Carrier is committed to delivering solutions that preserve the environment and comply with the European Union’s F-Gas Regulations. Aside from confirming its move toward low GWP refrigerants, Carrier in Europe has achieved a significant reduction of the refrigerant charge in its products of up to 50% over the last five years. Carrier has been working to select the best candidate to replace the HFC R-134a in screw and centrifugal chillers and HFC R-410A in scroll chillers, heat pumps and rooftop units. Products in this range are improving product efficiency by an average of 10% New Generation Refrigerants For screw chillers and heat pumps, Carrier chose HFO R-1234ze to replace HFC R-134a. With a GWP less than 1, according to the 5th Assessment Report of the International Panel for Climate Change (IPCC), R-1234ze(E) is not impacted by restrictions from the EU F-gas regulation or the Kigali Amendment of the Montreal Protocol on fluorinated greenhouse gases. It is part of the Carrier PUREtec™ family of long-term refrigerant solutions. Carrier was the first to launch the newest generation of its AquaForce® chillers with PUREtec™ refrigerant three years ago and it continues to grow with more than 300 units installed in Europe, Middle East and Africa, and more than 2 million cumulated hours and proven reliability that is a core value of Carrier. Products in this range are improving product efficiency by an average of 10%, already exceed Eco-design 2021 requirements and meet today the Kigali Amendment requirements for 2036. Carrier AquaEdge Carrier chose HFO R-1233zd(E) as the preferred long-term refrigerant for centrifugal chillers. With a GWP of 1, it is also not impacted by F-Gas regulations. The Carrier AquaEdge® 19DV is a good example of a successful range using this refrigerant. Carrier is pursuing its technological development for long term solutions For scroll commercial chillers and heat pump ranges, currently available compressor technology is not compatible with low GWP HFO refrigerants. Some solutions operate with mid-GWP HFC refrigerants and Carrier is developing a full range of cooling and heating products that will comply with and exceed Eco-design 2021 efficiency requirements and operate with mid-GWP HFC refrigerants. Operating Temperature Flexibility These ranges are expected to launch very soon and are optimized for energy efficiency while offering the same operating temperature flexibility as current units operating with R-410A. As technology leader in the heating, ventilating and air conditioning industry with its different chillers’ ranges, Carrier is pursuing its technological development for long term solutions with lower impact on the global warming potential and reaffirms its commitment to sustainability.

Keeping with its long history of sustained environmental responsibility, Carrier has once again taken a pivotal role in offering the refrigerant of the future. After extensive tests and evaluation, Carrier has identified R-454B, to be known commercially as Puron Advance, as its primary lower Global Warming Potential (GWP) solution to replace R-410A in all of its ducted residential and light commercial packaged solutions sold in North America. R-454B Puron Advance refrigerant Carrier will select the best-suited refrigerant for other applications as the need arises The new refrigerant, to be offered in these Carrier products beginning in 2023, is expected to surpass the requirements of anticipated future regulations. Carrier will select the best-suited refrigerant for other applications as the need arises. Carrier’s HVAC business, globally renowned for high-technology heating, air-conditioning and refrigeration solutions, is a part of Carrier, global provider of innovative HVAC, refrigeration, fire, security and building automation technologies and a unit of United Technologies Corp.. Carrier has been working with The Chemours Company, internationally recognized firm in fluorochemicals and refrigerant technology, who will produce and distribute the new refrigerant in North America. With a GWP of 466 – one-fifth that of R-410A – Puron Advance refrigerant was selected as the best solution to minimize environmental impact and energy use, while improving performance, safety, and longevity, based on the United Nations Montreal Protocol Kigali Agreement phase down plan for HFCs. Sustainable, responsible refrigerant solution Carrier has worked closely with regulators and research groups to develop standards, codes and regulations that will help ensure the safe use of R-454B. “Carrier is committed to the environment by providing efficient, responsible solutions to its customers. The move to Puron Advance refrigerant is the next logical step in the evolution of our industry,” said Matthew Pine, president, Residential HVAC, Carrier. The Chemours Company has played an integral role in the development of the refrigerant, R-454B He adds, “We carefully studied all alternatives and chose the most viable refrigerant with the lowest environmental impact for this product category. Innovation and technological advancement are in our DNA and we will continue to lead the way with the evolution of refrigerants of the future.” Partnership with The Chemours Company The Chemours Company has played an integral role in the development of the refrigerant, R-454B. Matthew further stated, “We designed R-454B to bring the optimal balance of performance, safety and sustainability to our customers and the market in the face of upcoming regulations,” said Diego Boeri, vice-president, Chemours Fluorochemicals. “It's exciting to see Carrier, with their history of market innovation, embrace R-454B as its long-term solution for North America as the industry prepares to move away from R-410A."

A key deadline for phasing out hydrochlorofluorocarbons (HCFCs) from residential air conditioning systems is less than a year away. Jan. 1, 2020, is the deadline after which there will be no U.S. production or import of HCFC-142b and HCFC-22 (also called R-22). The deadline is part of an incremental phazeout of HCFC consumption and production based on the U.S. commitment in the 1997 Montreal Protocol aimed at protecting stratospheric ozone. Section 605 of the Clean Air Act establishes phazeout targets for the chemicals. The phazeout will be complete in 2030, after which time there will be no production or import of any HCFCs. HCFC-142b retrofit refrigerant HCFC-142b is used in small quantities in refrigerant blends and as a retrofit refrigerant in motor vehicle ACs HCFC-142b is used in small quantities in refrigerant blends and as a retrofit refrigerant in motor vehicle air conditioners that previously used chloroflurococarbons (CFCs), which were eliminated in the mid-1990s for their potential to deplete the ozone layer. HCFC-22 is the most commonly used refrigerant in applications such as unitary air conditioners, cold storage, retail food refrigeration equipment, chillers and industrial process refrigeration. Any air conditioner or heat pump manufactured before 2010 likely uses HCFC-22 refrigerant. Hydrochlorofluorocarbons in air conditioning systems On Jan. 1, 2020, U.S. production or import of HCFC-22 and HCFC-142b will not be permitted in the United States. After this happens, only recycled/reclaimed or stockpiled quantities of HCFC-22 and HCFC-142b will be available for servicing existing equipment, and they will likely be more expensive. These substances have been in the process of being phazed out since 2015, when supplies were reduced by 90 percent. Since 2010, HCFC-22 and HCFC-142b have been available exclusively for use to service existing equipment.   There are several non-ozone-depleting alternatives to HCFC-22. They include R-134a and R-410A, which can be used in a new installation; and R-407C and R-407A, which can be used in a new or a retrofit installation. The most common alternative is R-410A, which is manufactured and sold under various trade names such as GENTRON AZ-20, SUVA 410A, and PURON. Significant New Alternatives Policy SNAP (Significant New Alternatives Policy) was established by the U.S. Clean Air Act to identify and evaluate substitutes for ozone-depleting substances. The program looks at overall risks to human health and the environment of existing and new substitutes, publishes lists and promotes the use of acceptable substances, and provides the public with information. EPA reviews alternative refrigerants and maintains a list of acceptable substitutes for household and light commercial air conditioning. For the last 25 years, the air conditioning and refrigeration industry has been working to reduce its use of CFC refrigerants, which are no longer available on new equipment. The industry has used alternative refrigerants and achieved higher efficiency ratings to achieve the goals. CFC refrigerants Long life of AC equipment has extended the continuing use of CFC refrigerants by existing equipment However, the long useful life of air conditioning equipment has extended the continuing use of CFC refrigerants by existing equipment. Green building groups have supported legislative action to reduce federal depreciation schedules for this equipment, which would accelerate the replacement of older equipment and hasten the total elimination of CFC refrigerant use. The HEAT Act, which Congress passed in 2017 as part of the landmark Tax Cuts and Jobs Act, reduced commercial HVAC expensing from 39 years to immediate (zero years). Phazing out ozone-depleting refrigerants The European Union is also committed to protecting the ozone layer and has some of the strictest regulations in the world. Since 2010, there has been a ban on the use of “virgin” HCFCs to service and maintain refrigeration and air conditioning equipment; use of reclaimed or recycled HCFCs for service or maintenance has been banned since 2015.

The new CIE in Denmark will meet a growing demand for a qualified workforce in the field of electronic engineering.
