Abstract

A compressor oil recovering apparatus is disclosed which is capable of re-supplying, to a compressor (83,84), oil separated in an oil separator (85,86) after emerging from the compressor. The compressor oil recovering apparatus includes an oil separator adapted to separate oil from a refrigerant discharged from a compressor, an oil recovering port (830,840) provided at the compressor, and an oil recovering tube (163,164) having one end connected to the oil separator, and the other end connected to the oil recovering port. A non-uniform oil distribution is prevented by temperature sensors (153,154) arranged in the compressors and a uniform distribution tube (150).
