Abstract:
The present invention addresses the problem of providing: a refrigerator oil composition that exhibits low hydrocarbon-based refrigerant solubility and has an appropriate solution viscosity when the hydrocarbon-based refrigerant is dissolved; and a mixed composition for a refrigerator, said composition containing the refrigerator oil composition. This problem is solved by preparing a refrigerator oil composition that is used in a refrigerant containing a hydrocarbon-based refrigerant, said composition containing at least one substance selected from aromatic ester-based compounds (A) represented by general formula (1). [In general formula (1), R1 is a straight chain or branched alkyl group having 5-24 carbon atoms, or a straight chain or branched alkenyl group having 5-24 carbon atoms. m is an integer of 2-4. The R1 moieties may be the same or different.]
