The present invention provides a composition containing a refrigerant (mixed refrigerant) having three properties of a coefficient of performance (COP) equal to or higher than that of R410A, a refrigeration capacity (Cap), and a sufficiently small GWP at the same time. Specifically, the present invention provides a composition containing a refrigerant containing CF 3 I, CO 2 (R744), and a composition selected from trifluoroethylene (HFO-1123), trans-1,2-di Vinyl fluoride [(E)-HFO-1132], cis-1,2-difluoroethylene [(Z)-HFO-1132], vinyl fluoride (HFO-1141) and 3,3,3-trifluoropropyne (TFP) at least one compound A. |
