Preferably, the primary heat exchanger 8 is a sleeve-and-tube heat exchanger. In addition, the secondary heat exchanger 9 is a counter-flow sleeve heat exchanger. As shown in Figures 2 to 4, the sleeve-and-tube heat exchanger is a concentric sleeve made of straight pipes of different diameters and connected by a U-shaped elbow. In this kind of heat exchanger, one kind of heat source goes in the tube, and the other kind of cold source goes in the ring gap, both of which can get a higher flow rate, so the heat transfer coefficient is larger. In addition, in the casing heat exchanger, the two fluids can be purely countercurrent, and the logarithmic average driving force is relatively large.

In this embodiment, the working process of the novel air-energy water dispenser is roughly as follows:

As shown in Figure 1, pure water enters the new air-energy water dispenser through the water inlet 6, and after being further purified by the filter 7, it enters the first-stage heat exchanger 8 to exchange heat with the high-temperature and high-pressure refrigerant to perform the first-stage Preheating, at this time, the water temperature is about 50 degrees, and the preheated water enters the secondary heat exchanger 9 for secondary preheating. At this time, the water temperature is about 80 degrees, and finally enters the boiling water tank 10. It can be heated and boiled, and can flow out from the water outlet 14 of the boiling water tank 10 for people to drink, and can also exchange heat with the preheated cold water through the secondary heat exchanger 9, and this part of the water flows through the first water flow opening regulator 17, Under the action of the first water flow opening degree regulator 17, the opening degree of the hot water is controlled to mix with the cold water to different temperatures in the warm water tank 12, and warm water is provided through the water outlet 15 of the warm water tank 12. In addition, the control center can control the first water flow opening regulator 17 and the second water flow opening regulator 18 according to the warm water temperature set by the user, so as to realize the supply of warm water at different temperatures and meet the needs of users for warm water of different temperatures. In addition, a part of the water that enters from the water inlet 6 and passes through the filter 7 can be cooled in the cold water tank 13 and passed through the water outlet 16 of the cold water tank 13 for drinking. In the heating cycle of the heat pump system, the refrigerant turns into a high-temperature and high-pressure gas through the action of the compressor 2, and exchanges heat with the cold water through the condenser 3 to provide heat energy. The low-grade energy in the air is absorbed in the device 5, thereby saving a part of electric energy.

In this embodiment, the new air-energy water dispenser operates through the vapor compression system, the refrigerant absorbs the low-grade energy in the air in the evaporator 5, and the refrigerant absorbs this part of heat energy and then enters the compressor 2, and the compressor 2 performs work Turn the refrigerant into high-temperature and high-pressure gas and enter the sleeve condenser 3 for heat exchange with hot water. This process makes full use of the low-grade energy in the air, saves energy consumption, and improves the energy efficiency ratio of the water dispenser. After the initial heat exchange in the primary heat exchanger 8, it can enter the secondary heat exchanger 9 to raise the temperature again, and finally use electric energy to heat the preheated water to boiling, which reduces the utilization of electric energy and fully utilizes the energy in the air and the energy released during the process of turning boiled water into warm boiled water, so as to achieve the purpose of energy saving.
