Alternative Refrigerants Continue to Rise in Popularity

I discussed a recent ruling from the U.S. Environmental Protection Agency (EPA) and industry trends associated with low global warming potential (GWP) in ACHR News. The EPA cannot require HVACR manufacturers to replace what they deem high-GWP refrigerants with lower-GWP replacements. That was the opinion of the U.S. Court of Appeals for the District of Columbia circuit judge Brett Kavanaugh on Jan. 27.
