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 CF3I, CO2 (R744), and at least one compound A selected from the group consisting of trifluoroethylene (HFO-1123), trans-1,2-difluoroethylene [(E)-HFO-1132], cis-1,2-difluoroethylene [(Z)—HFO-1132], fluoroethylene (HFO-1141), and 3,3,3-trifluoropropyne (TFP).
Claims5
A composition comprising a refrigerant,
- the refrigerant comprising CF3I, CO2 (R744), HFC-32, and at least one compound A selected from the group consisting of trifluoroethylene (HFO-1123), trans-1,2-difluoroethylene [(E)-HFO-1132], cis-1,2-difluoroethylene [(Z)-HFO-1132], fluoroethylene (HFO-1141), and 3,3,3-trifluoropropyne (TFP),
- wherein the refrigerant comprises 38 to 69 mass % of CF3I, 1 to 10 mass % of CO2, based on the total amount of CF3I, CO2, HFC-32, and compound A taken as 100 mass %.
