Abstract:
The present invention provides a refrigerator oil composition which satisfies both sludge dispersibility and prevention of wear and seizing of sliding parts made of aluminum and/or iron, and a compressor and a refrigeration apparatus using the refrigerator oil composition. The refrigerator oil composition is characterized by comprising a base oil which is at least one member selected from mineral oils and synthetic oils, and at least one polyamide compound having two or more amide groups in the molecule and being present in an amount of 0.01 to 5% by mass based on the total amount of the refrigerator oil composition.
