Refrigerator oil composition

摘要

Disclosed is a refrigerator oil composition comprising at least one base oil selected from mineral oils and synthetic oils, and at least one polyether compound having a kinematic viscosity of from 200 to 10000 mm2/sec at 100 DEG C. The composition has an excellent lubricating property, while specifically improving the lubricity of bearings. This is effective for preventing bearings from being seized and fatigued, and is suitable as a lubricating oil in refrigerators using hydrogen-containing Flon refrigerants, such as R134a, that do not cause environmental pollution.
