REFRIGERATING MACHINE WORKING FLUID COMPOSITION AND REFRIGERANT OIL |
| 摘要 |
A working fluid composition for a refrigerating machine of the invention comprises a refrigerant comprising difluoromethane and an unsaturated fluorinated hydrocarbon wherein a mass of the difluoromethane/the unsaturated fluorinated hydrocarbon is 95/5 to 10/90, and a refrigerating machine oil comprising at least one base oil selected from among polyol esters with a carbon/oxygen molar ratio of 3.2 to 5.8 and polyvinyl ethers with a carbon/oxygen molar ratio of 3.2 to 5.8. |
