the invention relates to the problem of supplying a mixed refrigerant that exhibits three types of performance that consist of a refrigerant capacity and performance coefficient that are identical to those of r410a, and a sufficiently low pag. the present invention solves the problem by providing a composition containing refrigerant, in which the refrigerant contains trans-1,2-difluorethylene (hfo-1132 (e)), trifluorethylene (hfo-1123) and 2,3,3,3 -tetra-fluor-1-propene (r1234yf). |
