Abstract:
The present invention provides a refrigerator oil composition comprising a base oil which is at least one member selected from mineral oils and synthetic oils, and at least one imide compound, said imide compound in an amount of 0.01 to 5% by mass based on the total amount of the refrigerator oil composition, and also provides a compressor and a refrigeration apparatus using the refrigerator oil composition. The refrigerator oil composition and the compressor and the refrigeration apparatus using the refrigerator oil composition satisfy both sludge dispersibility and prevention of wear and seizing of a sliding part made of aluminum and/or iron.
