AHRI, NRDC Align on Refrigerant Phaseout

摘要

The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) and the Natural Resources Defense Council (NRDC) issued a joint letter to the U.S. Environmental Protection Agency (EPA) in support of changing the status of certain refrigerants used in liquid chillers under the EPA's Significant New Alternatives Policy (SNAP) program, effective Jan. 1, 2025. The two groups took this action following lengthy discussions on the importance of moving beyond high-GWP (global warming potential) refrigerants used in chillers and consideration of factors, such as the safety of alternatives, the continued improvement of system efficiency, reasonable product development timelines, and the avoidance of market migration. The effective date was negotiated with those factors in mind.
