It is to provide a lubricating oil composition for a compression refrigerator, which is excellent in the thermal/chemical stability even when used in a compression refrigerator that uses a saturated fluorinated hydrocarbon refrigerant having a lower global warming potential and a fewer carbon atoms, by including in a base oil an organic compound having a double bond in a molecule, which is at least one kind selected from an organic compound having at least two non-conjugated double bonds in the molecule, a terpene compound having a double bond in the molecule, and C12 to C30 aliphatic unsaturated hydrocarbon having one double bond in the molecule.
                            本发明旨在提供一种用于压缩式制冷机的润滑油组合物,该组合物即使用于使用全球变暖潜能值较低且碳原子数较少的饱和含
氟碳氢化合物制冷剂的压缩式制冷机中,也具有优异的热稳定性/
化学稳定性、在基础油中加入分子中含有双键的有机化合物,该双键至少选自分子中含有至少两个非共轭双键的有机化合物、分子中含有一个双键的萜烯化合物和分子中含有一个双键的 C12 至 C30 脂肪族不饱和烃中的一种。
