Abstract

See full text

The present disclosure provides a composition comprising a refrigerant characterized by having a coefficient of performance (COP) and a refrigerating capacity equivalent to or higher than those of R404A, and having a sufficiently low GWP. Specifically, the present disclosure provides a composition comprising a refrigerant, the refrigerant comprising trans-1,2-difluoroethylene (HFO-1132 (E)) and 2,3,3,3-tetrafluoropropene (HFO-1234yf), wherein HFO-1132 (E) is present in an amount of 35.0 to 65.0 mass %, and HFO-1234yf is present in an amount of 65.0 to 35.0 mass %, based on the total mass of HFO-1132 (E) and HFO-1234yf, and wherein the refrigerant is for use in operating a refrigeration cycle in which the evaporation temperature is −75 to −5° C.
