ABSTRACT:
Disclosed is a refrigerator oil composition comprising at least one base oil selected from mineral oils and synthetic oils, and at least one polyoxyethylene-type nonionic surfactant. The composition has an excellent lubricating property, while specifically improving the lubricity between aluminium materials and steel materials. This is effective for preventing such materials from being seized and worn, and is suitable as a lubricating oil in refrigerators using hydrogen-containing Flon refrigerants, such as R134a, that do not cause environmental pollution.
