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.

On the other hand, the heat source fluid is caused to flow from the inlet 9 and is heated via the heat transfer tube 10, whereby the refrigerant liquid is heated and flows out from the gas outlet 14. At this time, the refrigerant liquid foams and flows into the adjacent tanks, but by contacting the heat transfer tube 10, the refrigerant component can be evaporated in the process of flowing to the tank on the outlet 12 side, and these tanks can be quantified. The structure is such that sufficient time can be secured to evaporate the refrigerant component in the liquid. Further, the respective tanks are connected by minute holes at the bottom of the partition plate so that the liquid containing only the lubricating oil in the previous tank is caused to flow to the outlet side and the time is secured.
