Abstract
Disclosed is a composition comprising difluoromethane (R-32), 2,3,3,3-tetrafluoropropene (R-1234yf), and isobutane (R-600a). A refrigeration system, including a hermetic compressor and a refrigerant composition. The refrigerant composition includes difluoromethane (R-32), 2,3,3,3-tetrafluoropropene (R-1234yf), and isobutane (R-600a).
Claims18
A composition comprising a refrigerant consisting essentially of 15 to 22 weight percent difluoromethane, 70 to 84 weight percent 2,3,3,3-tetrafluoropropene, and 1.0 to 10 weight percent isobutane.
A method of replacing a first refrigerant composition comprising R-404A, R-457A, R-290, or R-454C with a second refrigerant composition comprising 70 to 84 weight percent 2,3,3,3-tetrafluoropropene, 15 to 22 weight percent difluoromethane, and 1.0 to 10 weight percent isobutane, wherein the replacing is performed in a refrigeration system including a hermetic compressor.
