Abstract
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.
