The present invention provides a lubricating oil composition for refrigerating machine capable of enhancing the anti-wear property of the entire system when used together with 1,1,1,2-tetrafluoroethane (HFC-134a) which does not act as an extreme-pressure agent.
This composition exhibits an anti-wear property superior to that of the existing lubricating oil composition for refrigerating machine using CFC-12.
The ester expressed in any one of Formulae (I), (V), (VI) is used as the base oil or as an additive to the base oil. (The symbols in the formulae are as specified in Specification herein.)
本发明提供了一种用于制冷机的润滑油组合物,该组合物与不作为极压剂的 1,1,1,2- 四氟乙烷(HFC-134a)一起使用时,能够提高整个系统的抗磨损性能。
这种组合物的抗磨损性能优于使用 CFC-12 的现有制冷机润滑油组合物。
式(I)、(V)、(VI)中任一式所表示的酯可用作基础油或基础油的添加剂(式中符号如本说明书所述)。
