The present invention provides a freezer oil composition which is free from a scissor of a refrigeration compressor, which can be used together with HFC refrigerants containing HFC-134a and / or HFC-125, and which has excellent lubricity and high reliability over a long period of time. And a refrigerator composition comprising the refrigerator oil composition and an HFC refrigerant containing HFC-134a and / or HFC-125. (A) Alkylbenzene having a molecular weight of 200 to 350. Containing HFC-134a and / or HFC-125 consisting of 70 to 99% by weight of alkylbenzene containing at least 60% by weight based on the total amount of the component (A) and 30 to 1% by weight containing oxygen (B). It is characterized in that the refrigeration fluid composition for the HFC refrigerant comprising a freezer oil composition and the freezer oil composition and HFC refrigerant containing HFC-134a and / or HFC-125. |
