摘要：
The present disclosure provides a composition comprising a refrigerant (mixed refrigerant), the composition having three types of performance; i.e., a coefficient of performance (COP) and a refrigerating capacity (Cap) that are equivalent to or higher than those of R404A and/or R410A, and a sufficiently low GWP. The present disclosure specifically provides a composition comprising a refrigerant, the refrigerant comprising difluoromethane (HFC-32), 2,3,3,3-tetrafluoropropene (HFO-1234yf), and at least one of 1,1-difluoroethylene (HFO-1132a) and tetrafluoroethylene (FO-1114).
