United States. The Chemours Co. announced that R-454B, its next-generation refrigerant sold as Opteon XL41, has been selected by Carrier Corp., after extensive testing and evaluation, as the primary refrigerant with the lowest Global Warming Potential (GWP) to replace R-410A in packaged residential and light commercial products sold by Carrier in North America beginning in 2023.
The selection of the R-454B allows Carrier to achieve its performance standards, while exceeding the anticipated requirements of future regulations. With a GWP of 466, Opteon XL41 (R-454B) reduces CO2 emissions by 78 percent and improves energy efficiency compared to R-410A, and provides a reduction of more than 30 percent in GWP compared to R-32, another industry candidate to replace the R-410A. Opteon XL41 was specifically developed to achieve the maximum possible reduction in GWP to meet long-term regulatory requirements.
"As the world moves towards more environmentally sustainable solutions, equipment manufacturers are looking for lower GWP options that meet future regulations and can meet performance. Opteon XL41 accomplishes that," said Diego Boeri, vice president of Chemours Fluorochemicals. "We are thrilled to be working collaboratively with Carrier to bring about transformative change for the air conditioning industry. Chemours is committed to providing world-class technology through responsible chemistry that reduces the impact on global climate change."
Opteon XL41 (R-454B) is an ASHRAE Class A2L (lower flammability) hydrofluoroolefin-based refrigerant and was chosen by Carrier for its balance of performance, energy use and safety, combined with the longevity and peace of mind that a low GWP replacement for R-410A offers its customers. Carrier will market the R-454B as Puron Advance throughout North America.
"Carrier is committed to the environment by providing efficient and responsible solutions to its customers. The switch to Puron Advance refrigerant is the next logical step in the evolution of our industry," said Matthew Pine, president of Residential HVAC Carrier. "We carefully studied the alternatives and chose the most viable refrigerant with the least environmental impact for the application of our products. Innovation and technological advancement are in our DNA and we will continue to lead the way with the evolution of the refrigerants of the future."
