<p>PROBLEM TO BE SOLVED: To provide an accumulator which returns an ice machine oil to a compressor without needing a large heating value for heating, prevents reduction of the volumetric efficiency of the compressor, and improves the reliability of the compressor.SOLUTION: An accumulator 8 includes: a closed container 18 having a storage region for storing a refrigerant, into which an ice machine oil blends, at a lower part; a division member 21 which divides the storage region into at least a first region 22 and a second region 23; a refrigerant inlet pipe 19 which opens in the closed container 18; a refrigerant outlet pipe 20 which opens in the closed container 18; a return oil pipe 11 which opens in the first region 22; and a heat exchanger 17 for heating which passes through the first region 22 or contacts with an outer wall surface of the closed container 18 that faces the first region 22 and heats the liquid refrigerant, into which the ice machine oil blends, in the first region 22 to separate the liquid refrigerant from the ice machine oil.</p> |
