Abstract:
The present invention addresses the problem of providing: a refrigerator oil composition which has a suitable dissolved viscosity when a hydrocarbon-based refrigerant is dissolved and in which the hydrocarbon-based refrigerant has a low solubility; and a mixed composition for a refrigerator, which contains said refrigerator oil composition. This problem can be solved by this refrigerator oil composition in which a refrigerant containing a hydrocarbon-based refrigerant can be used and which contains one or more types of polyol ester compound (X) selected from the group consisting of complete esters and half esters of a specific pentaerythritol-based compound (A) and a fatty acid (B). The fatty acid (B) includes a short chain fatty acid (B1) having 2-9 carbon atoms. The short chain fatty acid (B1) includes a specific linear short chain fatty acid (B1-1). The content of the short chain fatty acid (B1) is more than 50 mol% relative to the entire amount of the fatty acid (B).
