There are provided a refrigerating machine oil which can easily remove a sludge generated in a refrigerant circuit and is easy to return to a compressor and a refrigerator employing the same. A refrigerating machine oil obtained by mixing an alkylbenzene oil and an ether oil is employed in a refrigerant circuit. A sludge generated on an inner surface of a small-diameter portion of a capillary ( ) is exfoliated and removed by the alkylbenzene oil while maintaining lubricating performance of a compressor ( ) with the ether oil that is well dissolved in an HFC refrigerant, thereby preventing capillary clogging.

Refrigerating machine oil and refrigerator using the same

A blade 8 is integrally fixed to a roller 7 mounted around an eccentric section 22 of a drive shaft 21. The blade 8 extend radially outwardly of the roller 7, and partitions the inside of a cylinder chamber 41 into a compression chamber X and a suction chamber Y. A protruded end portion of the blade 8 is received in a reception groove 11a of a support member 11 which is pivotally supported by a stationary member 4. A substitute fleon refrigerant is used as a working fluid in the cylinder chamber 41, and an oil adapted to the substitute fleon refrigerant is used as a lubricating oil for a compressor CP. While using the substitute fleon refrigerant, the deterioration of the oil in the compressor is prevented.
