    Abstract: To provide a polyalkylene glycol-based refrigerant oil for refrigerators using ammonia as a refrigerant.
    The present invention provides a lubricant for refrigerators using ammonia refrigerant, comprising polyethers serected from the group consisting of a polyether represented by the following general formula (1)

            X-{-O-(AO) n -H} p      (1)

    (wherein X is a residue of a monool or polyol from which a hydroxyl group is eliminated; (AO) n is a polyoxyalkylene group formed by copolymerization of EO and an AO having 3 or more carbon atoms; n is 2 or more; and p is a valence of X) and having 50% or more of secondary hydroxyl groups among the hydroxyl groups located at the terminal of the structure based on the total hydroxyl groups, or
    a polyether represented by the following general formula (2)

            X-{-O-(AO 1 ) a -(AO 2 ) b -H} p      (2)

    (wherein X is a residue of a monool or polyol from which a hydroxyl group is eliminated; (AO 1 ) n is a polyoxyalkylene group formed by copolymerization of ethylene oxide and propylene oxide and/or butylene oxide; AO 2 is an oxyalkylene group having 3 or more carbon atoms; a is 2 or more; b is 1 or more; and p is a valence of X).
