Abstract:
The working fluid composition for a refrigerating machine of the invention is characterized by comprising an ester of a polyhydric alcohol and a fatty acid with a content of a C5-C9 branched fatty acid of 50-100% by mole, and a fluoropropene refrigerant and/or trifluoroiodomethane refrigerant. The refrigerating machine oil of the invention is characterized by comprising an ester of a polyhydric alcohol and a fatty acid with a content of a C5-C9 branched fatty acid of 50-100% by mole, and by being used together with a fluoropropene refrigerant and/or trifluoroiodomethane refrigerant.
