REFRIGERATION MACHINE OIL COMPOSITION, COMPRESSOR USING THE SAME AND REFRIGERATION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a refrigeration machine oil composition which secures the lubrication of a sliding site on activating and driving a refrigeration machine compressor, a compressor using the refrigeration machine oil composition, and a refrigeration apparatus comprising the compressor.

SOLUTION: The refrigeration machine oil composition is used in a refrigeration machine compressor in which at least part of a sliding surface of the member constituting a compression mechanism part is coated with a lubrication film-forming composition using a resin having a heat distortion temperature of not lower than 100°C as a binder and containing a solid lubricant, and comprises a base oil composed of a polyoxyalkylene glycol having a kinematic viscosity at 100°C of 3-50 mm2/s and a compound selected from an amide compound having a specific structural formula, an amidated amino acid compound, and an aliphatic amine in an amount of 0.01-1 mass% based on the total amount of the refrigeration machine composition. The compressor uses the refrigeration machine composition and the refrigeration apparatus comprises the compressor.
