The high-pressure refrigerant compressed by is liquefied in the condenser 2, passes through the expansion valve 3, and reaches the evaporator 4. At this time, the refrigeration compressor 1
Since the lubricating oil enclosed inside is contained in the circulating refrigerant and discharged, the lubricating oil of the refrigeration compressor 1 gradually decreases. The discharged lubricating oil stays inside the evaporator 4, so the inlet valve (stop valve) 6 is opened and the oil separating device 5 is opened.
Take out a part of the refrigerant. Therefore, the inlet valve 6 is closed, the heat source fluid is caused to flow from the inlet 9, and the heat transfer tube 10 heats the refrigerant liquid. The heated refrigerant liquid is gasified, and the refrigerant gas outlet 1
Return from 4 to the refrigeration compressor 1. After a certain time, the oil separation device 5
Only the lubricating oil was left as the internal liquid, and it was returned to the refrigeration compressor 1 from the lubricating oil outlet 12 through the valve 7.
