    Abstract: This invention provides a refrigerator working fluid composition characterized by excellent compatibility, lubricating ability, thermal stability, and electrical insulation capacity, and comprising a refrigerating machine oil and a hydrofluorocarbon compound, wherein the refrigerating machine oil comprises:

    (A) 100 parts by weight of at least one ester compound selected from the group consisting of:

    (1) ester compounds obtained from

    (a) an aliphatic polyhydric alcohol having 1 to 6 primary hydroxyl groups,
    (b) a straight or branched chain saturated aliphatic monocarboxylic acid having 2 to 9 carbon atoms or a derivative thereof, and
    (c) a straight or branched chain saturated aliphatic dicarboxylic acid having 2 to 10 carbon atoms or a derivative thereof; and

    (2) ester compounds obtained from

    (a) an aliphatic polyhydric alcohol having 1 to 6 primary hydroxyl groups,
    (d) a straight or branched chain saturated aliphatic monohydric alcohol having 1 to 10 carbon atoms, and
    (e) a polycarboxylic acid having 2 to 10 carbon atoms or a derivative thereof; and


    (B) at least one compound selected from the group consisting of 0.1 to 5.0 parts by weight of a triaryl phosphate, a triaryl phosphite, or a mixture thereof; 0.001 to 0.1 parts by weight of benzotriazole, a derivative thereof, or a mixture thereof; 0.05 to 2.0 parts by weight of an epoxy group-containing compound; and 0.001 to 2.0 parts by weight of a metal deactivator having a chelating function.
