In this embodiment, the refrigerant compressor, the plate heat exchanger, the condenser, the throttling device, the evaporator, the gas-liquid separator, the cold-hot water tank, and the circulating water pump are all fixedly connected by pipelines. As shown in fig. 19, during the extraction and concentration process, the refrigerant compressor 61, the plate heat exchanger 62, the condenser 63, the throttling device 64, the evaporator 65, and the gas-liquid separator 66 function to provide a refrigerant carrying medium to the condensed water tank 675 and a heat carrying medium to the heated water tank 671. On the basis of consuming certain electric energy, the refrigerant compressor 61 obtains the low-temperature and low-pressure gaseous refrigerant which absorbs heat from the evaporator 65 from the gas-liquid separator 66, and the low-temperature and low-pressure gaseous refrigerant is compressed into a high-temperature and high-pressure gaseous refrigerant and is conveyed to the plate heat exchanger 62; the heat carrier in the heating water tank enters an inlet of the circulating water pump 68 through the hot water circulating outlet 678, then enters the plate heat exchanger through an outlet of the circulating water pump 68, exchanges heat with the plate heat exchanger, and finally returns to the heating water tank 671 through the hot water circulating inlet 679, so that the heat carrier in the heating water tank 671 is heated, and at the moment, the high-temperature and high-pressure gaseous refrigerant is condensed into a high-pressure medium-temperature gas-liquid mixed refrigerant.

Since the inside diameter of the evaporator 65 is much larger than the diameter of the capillary member of the throttle device 64, the pressure of the liquid refrigerant suddenly decreases, and the liquid refrigerant is rapidly evaporated. The refrigerant carried by the condensed water tank 675 enters the inlet of the circulating water pump 68 through the condensed water circulating outlet 6710 and enters the evaporator 65 through the outlet of the circulating water pump 68, and the liquid refrigerant rapidly evaporated in the evaporator 65 absorbs heat from the refrigerant carried by the condensed water tank 675 until the liquid refrigerant is completely gasified and converted into low-pressure and low-temperature gaseous refrigerant, so that the process of cooling the refrigerant carried by the condensed water tank 675 is completed. The low pressure, low temperature gaseous refrigerant is filtered back into the refrigerant compressor by the gas-liquid separator 66. The cooling of the refrigerant carried by the condensed water tank and the heating of the heat carrying medium of the heating water tank are realized by the repeated circulation. The heating mechanism 672 has the effect that when the heat carrier in the heating water tank does not reach the set temperature, the heat carrier is heated to reach the required use temperature through auxiliary heating.
