Abstract:
An object of the present invention is to provide a mixed refrigerant having three types of performance; i.e., a refrigerating capacity (also referred to as cooling capacity) and a coefficient of performance (COP) that are equivalent to those of R410A, and a sufficiently low GWP. Provided as a means for achieving the object 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).
