Abstract
The present invention provides a composition comprising a refrigerant (mixed refrigerant) having three types of performance, i.e., a coefficient of performance (COP) and refrigerating capacity (Cap) that are equivalent to or higher than those of R410A, and a sufficiently low GWP. Specifically, the present invention provides a composition comprising a refrigerant, the refrigerant comprising CFI, CO(R744), and at least one compound A selected from the group consisting of trifluoroethylene (HFO-1123), trans-1,2-difluoroethylene [(E)-RFC-1132], cis-1,2-difluoroethylene [(Z)-HFO-1132], fluoroethylene (HFO-1141), and 3,3,3-trifluoropropyne (TFP).
