Several large U.S. refrigeration users, including Whole Foods, Target, and the U.S. Defense Commissary Agency (DeCA) have announced plans to increase their use of natural refrigerants, particularly CO2 transcritical, at the recent ATMOsphere America 2017 conference. Whole FoodsMarket will retrofit 15 to 30 stores per year with natural refrigerant-based systems, said Tristam Coffin, its director of sustainability and facilities. A representative for Targetsaid the retail company would install its first two transcritical CO2 systems, in California and Minnesota, this year. DeCA, which is responsible for supermarkets on U.S. military bases worldwide, said of CO2 transcritical installations that DeCA “can make it work anywhere,” even in warm ambient climates.
