  Disclosed is a lubricating oil composition for refrigeration machine comprising 100 parts by weight of a carboxylic ester having a number-average molecular weight (Mn) of 200 to 5,000 and a kinematic viscosity at 100 °C of 2 to 100 cSt or a carbonic ester having a number-average molecular weight (Mn) of 200 to 5,000 and a kinematic viscosity at 100 °C of 2 to 100 cSt, and 0.001 to 15 parts by weight of a fluoroalkyl group-containing alcohol. The lubricating oil composition for refrigeration machine can extremely reduce the amount of metal abrasion at the slide part of the compression type refrigeration machine in which hydrogenated fluorocarbon (HFC) such as R-134a is used as a refrigerant. This composition can be also used for refrigeration machines of other types than the compression type because of its excellent lubricating properties.

  本发明公开了一种用于制冷机的润滑油组合物，该组合物包含 100 重量份的羧酸酯（其数均分子量 (Mn) 为 200 至 5,000 且在 100 °C 时的运动粘度为 2 至 100 cSt）或碳酸酯（其数均分子量 (Mn) 为 200 至 5,000 且在 100 °C 时的运动粘度为 2 至 100 cSt），以及 0.001 至 15 重量份的含氟烷基醇。这种制冷机润滑油组合物可以极大地减少使用氢化碳氟化合物（HFC）（如 R-134a）作为制冷剂的压缩式制冷机滑动部分的金属磨损量。除压缩式制冷机外，该组合物还可用于其他类型的制冷机，因为它具有出色的润滑性能。
