要約
(EN)

The present disclosure provides a composition comprising a refrigerant characterized by having a coefficient of performance (COP) and a refrigerating capacity (Capacity) equivalent to or higher than those of R134a, and having a sufficiently low GWP. The present disclosure is, specifically, a composition comprising a refrigerant, the refrigerant comprising cis-1,2-difluoroethylene (HFO-1132(Z)) and 2,3,3,3-tetrafluoropropene (HFO-1234yf), wherein HFO-1132(Z) is present in an amount of 53.0 to 59.5 mass %, and HFO-1234yf is present in an amount of 47.0 to 40.5 mass %, based on the total mass of IFO-1132(Z) and HFO-1234yf.
