the invention relates to the problem of supplying a mixed refrigerant having a combination of three types of performance, that is, a cooling capacity (also referred to as cooling capacity) and a performance coefficient (cdd) that are equivalent to those of r410a and a low enough pag. as a means of solving the problem, a composition containing a refrigerant is provided, wherein the refrigerant contains a trans-1,2-difluorethylene (hfo-1132 (e)), a trifluorethylene (hfo-1123) and a 2,3 , 3,3-tetrafluor-1-propene (r1234yf). |
