An object is to provide a mixed refrigerant having three types of performance, i.e., a refrigerating capacity (also referred to as refrigeration capacity and cooling capacity) and a coefficient of performance that are equivalent to those of R410A, and a sufficiently low GWP. Provided as a means for a solution is a composition comprising a refrigerant, the refrigerant comprising trans-1,2-difluoroethylene (HFO-1132(E)), trifluoroethylene (HFO-1123), and 2,3,3,3-tetrafluoro-1-propene (R1234yf), and R32. |
