Document Type and Number:
WIPO Patent Application WO/2022/196689
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a refrigerator oil composition which can effectively suppress an increase in acid value, even if there is an increase in the proportion of a unsaturated fluorohydrocarbon compound (HFO) in a refrigerant. This problem is solved by a refrigerator oil composition used for a refrigerant that contains one or more unsaturated fluorohydrocarbon compounds selected from compounds represented by the following general formula (1): CxFyHz [where x is an integer of 2-6, y is an integer of 1-11, z is an integer of 1-11, and one or more unsaturated carbon-carbon bonds are included in the molecule]. The refrigerator oil composition contains (A) a base oil and (B) one or more silicone compounds selected from the group consisting of (B1) unmodified silicone and (B2) modified silicone, wherein the content of the silicone compound (B) is not less than 0.05 mass% with respect to the entire amount of the refrigerator oil composition.
