The working principle of one embodiment of the utility model is as follows:
firstly, the incoming water is primarily heated by the incoming water preheating device 3, then the water is heated to a specified temperature by the secondary heating device 7, and then the hot water is stored in the heat preservation water tank 12 for later use. The heat collecting plate 1 collects solar energy and transfers the solar energy to the first heat radiating coil 17 through heat conducting oil and a pipeline, and water is preheated through the first heat radiating coil 17. The fourth temperature sensor detects the temperature of the heat collecting plate 1 in real time, the first temperature sensor detects the temperature in the first water tank 16 in real time and compares the detected temperature with the external temperature, and if the temperature in the first water tank 16 is higher than the temperature of the heat collecting plate 1, the controller controls the first pump body 15 to stop operating and simultaneously controls the electric gate valve 2 to be closed. The incoming water can be heated to about 50 ℃ by the incoming water preheating device 3.
The air source heat pump carries out secondary heating on the incoming water, and firstly: the port of the electric three-way valve 9 is connected with the inlet end of the throttling device 8, the outlet of the throttling device 8 is connected with the inlet end of the evaporator 6, and at the moment, the port of the electric three-way valve 9 is connected and closed with one end of the supercooling heater 10. The compressor 4 compresses the refrigerant and sends the compressed refrigerant to the second heat dissipation coil 20 to release heat energy, so as to heat the water in the second water tank 21. The refrigerant directly enters the throttling device 8 through the electric three-way valve 9 and then enters the evaporator 6 to be evaporated and absorb the heat energy in the air, and then returns to the compressor 4 to enter the next cycle, the low-temperature heating of water is completed in the process, and the incoming water can be heated to about 70 ℃.
When the water in the second water tank 21 is heated to a certain temperature, the electric three-way valve 9 is communicated with the supercooling heater 10, the other end of the supercooling heater 10 is connected to the inlet of the throttling device 8 through the third one-way valve 11, and meanwhile, the electric three-way valve 9 is connected and closed with the inlet end of the throttling device 8. At this time, the refrigerant, which has released heat energy through the second heat dissipation coil 20, enters the supercooling heat exchanger 10 through the electric three-way valve 9, and is further condensed by the supercooling heat exchanger 10. The refrigerant is taken away certain heat by the air when passing through the supercooling heat exchanger 10 to form a supercooling state, then is further taken away the heat by the low-temperature condensate water left from the evaporator 6, is further supercooled, obtains higher supercooling degree under the condition of ensuring high condensation temperature, finally forms the supercooling degree lower than the water temperature in the water tank, is throttled by the throttling device 8, evaporates in the evaporator 6 and returns to the compressor 4. The condensed water of the air generated by the evaporator 6 in the heat absorption process can further cool the supercooling heat exchanger 10 at the lower part of the evaporator 6 due to the gravity, and the incoming water can be heated to about 90 ℃ in the process.
After the water is heated to a specified temperature by the secondary heating device 7, the hot water is stored in the hot water tank 12 for standby. The first water tank 16, the second water tank 21 and the holding water tank 12 are all provided with liquid level sensors for preventing the liquid levels in the first water tank 16, the second water tank 21 and the holding water tank 12 from being too high or too low.

The first water tank 16, the second water tank 21 and the heat-insulating water tank 12 are all provided with heat-insulating layers to prevent heat loss.
