ABSTRACT:
A refrigerating machine oil composition suitable for a compressor using a hydrofluorocarbon as a refrigerant, which comprises 100 parts by weight of a polyol ester as a base oil, from 7.0 to 15.0 parts by weight of a phosphate, and from 0.2 to 3.0 parts by weight in total of a 1,2-epoxyalkane and/or a vinylcyclohexene dioxide. The use of the refrigerating machine oil composition improves wear resistance of sliding portions of compressors and is free from the formation of sludges derived from the polyol ester used as a base oil of the oil composition. A rotary compressor using the oil composition is also disclosed.
