Abstract: |
|||
| A refrigerating machine oil composition which comprises a polyol ester as a base oil, a phosphorothionate, a phosphorus compound additive other than phosphorothionates, and a glycidyl ester type epoxy compound. In a refrigerating/air-conditioning apparatus employing an HFC refrigerant, etc., the refrigerating machine oil composition can combine lubricating properties and stability on a high level. The refrigerating/air-conditioning apparatus can hence be stably operated over long. | |||
