The problem is to provide a mixed refrigerant that has the same refrigerating capacity (Refrigeration Capacity. Also called Cooling Capacity.) and Coefficient of Performance (COP) as R410A, and has a sufficiently small GWP. . As a solution, a composition is provided, which is a composition comprising a refrigerant, wherein the refrigerant comprises trans-1,2-difluoroethylene (HFO-1132(E)), trifluoroethylene (HFO- 1123) and 2,3,3,3-tetrafluoro-1-propene (R1234yf), R32. |
