Abstract
The present invention provides a refrigerating machine oil composition for use in a compressor for a refrigerator in which a sliding surface of at least a part of constitutional members of the compressor is coated with a lubrication film-forming composition containing a resin having a heat distortion temperature of 100° C. or higher as a binder, and a solid lubricant, wherein the refrigerating machine oil composition contains a base oil made of a polyoxyalkylene glycol having a kinematic viscosity of from 3 to 50 mm/s as measured at 100° C., and a compound selected from the group consisting of amide compounds, amidated amino acid compounds and aliphatic amines having a specific structural formula which compound is contained in an amount of from 0.01 to 1% by mass on the basis of a total amount of the refrigerating machine oil composition, the refrigerating machine oil composition being capable of ensuring a good lubrication of sliding portions of the compressor upon starting operation of the compressor and during the operation; a compressor using the refrigerating machine oil composition; and a refrigerating apparatus including the compressor.
