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).
Claims36
A composition comprising a refrigerant consisting essentially of from about 15 to 22 weight percent difluoromethane, from about 70 to 84 weight percent 2,3,3,3-tetrafluoropropene, and from about 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.
A method of operating a hermetic compressor as part of a refrigeration system, comprising the steps of:
- receiving by a hermetic compressor a refrigerant composition including difluoromethane (R-32), 2,3,3,3-tetrafluoropropene (R-1234yf), and isobutane (R-600a);
- compressing by the hermetic compressor the refrigerant composition;
- wherein the discharge temperature of the compressor is between 80.0° C. and 100.0° C.
