[0024] Working principle: When in use, the refrigerant is compressed by the compressor 2 to become a high-temperature and high-pressure gas. The high-temperature and high-pressure gas is then cooled by the condenser 4 to become a high-pressure liquid refrigerant. After the high-pressure liquid refrigerant enters the evaporator 5, due to the pressure reduction, it becomes a low-temperature and low-pressure refrigerant vapor, which is used to cool the object to be cooled. It is then recovered through the recovery pipe 14, and the recovered steam enters the storage tank 7, pushing the piston 20 up, and pushing the condensed water above the piston 20 into the water tank 8 through the connecting pipe 13. The liquid level detector 17 detects the liquid level, thereby measuring the amount of steam in the storage tank 7.
