Refrigerants are all the talk these days in refrigeration. That was evident at the 66th International Air-Conditioning, Heating, and Refrigerating Exposition (AHR) in New York City. Much of the water-cooler banter centered on newer refrigerants and new equipment.
The late January expo occurred in the midst of a comment period (extending to March 10) regarding the U.S. Environmental Protection Agency’s (EPA) final phase out proposals concerning production and importation of hydrochlorofluorocarbon (HCFC)-22.
