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-epoxy-alkane 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.
一种适用于使用氢氟碳化合物作为制冷剂的压缩机的冷冻机油组合物,它包括 100 重量份作为基础油的多元醇酯、7.0 至 15.0 重量份的磷酸盐和 0.2 至 3.0 重量份的 1,2-环氧烷和/或乙烯基环己烯二氧化物。使用该冷冻机油组合物可以提高压缩机滑动部分的耐磨性,并且不会形成由用作油组合物基础油的多元醇酯产生的油泥。此外,还公开了一种使用该油组合物的旋转式压缩机。
