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.
Claims4
A refrigerant composition consisting of FO-1216 and a hydrofluoroolefin, wherein the hydrofluoroolefin is at least one member of HFO-1234ze and HFO-1243zf.
A refrigerant composition comprising FO-1216 and a halogenated ethylene, wherein the halogenated ethylene is at least one member selected from the group consisting of FO-1114, HFO-1123, HFO-1132(E), HFO-1132(Z), HFO-1132a, and HFO-1141, and the halogenated ethylene is present in an amount of 10 to 50 mol % based on the total amount of the FO-1216 and the halogenated ethylene taken as 100 mol %.
