The present invention provides a refrigerator oil composition which satisfies both sludge dispersibility and prevention of wear and seizing of sliding parts made of aluminum and/or iron, and a compressor and a refrigeration apparatus using the refrigerator oil composition.
The refrigerator oil composition is characterized by comprising a base oil which is at least one member selected from mineral oils and synthetic oils, and at least one polyamide compound having two or more amide groups in the molecule and being present in an amount of 0.01 to 5 % by mass based on the total amount of the refrigerator oil composition.
本发明提供了一种既能满足油泥分散性又能防止铝和/或
铁制滑动部件磨损和卡死的冷冻机油组合物,以及使用该冷冻机油组合物的压缩机和制冷设备。
该冷冻机油组合物的特点是包括至少一种选自矿物油和合成油的基础油,以及至少一种分子中含有两个或两个以上酰胺基团的聚酰胺化合物,其含量为冷冻机油组合物总量的 0.01 至 5%(质量百分比)。
