Abstract:
Provided is a refrigerant composition that has a low GWP; is non-flammable or mildly flammable; and has a refrigerating capacity (Cap) and/or coefficient of performance (COP) equivalent to or higher than those of traditional refrigerants, such as R-134a, R-410A, R-123, or R-404A, when used as an alternative refrigerant for these traditional refrigerants. Specifically, provided is a refrigerant composition containing FO-1216 and a hydrofluoroolefin, wherein the hydrofluoroolefin is at least one member of HFO-1234ze and HFO-1243zf.
