[0025] The solar heat supply unit 200 and the air energy unit heat supply unit 300 can both provide heat for the heat collecting and water supplying tank 100.

[0026] In the hot water supply system provided by the present application, the heat collecting and water supplying tank 100, the solar heat supply unit 200 and the air energy unit heat supply unit 300 are included. The solar heat supply unit 200 and the air energy unit heat supply unit 300 are both connected with the heat collecting and water supplying tank 100, and both can provide heat for the heat collecting and water supplying tank 100. In the use process, the solar heat supply unit 200 can be used to provide heat for the heat collecting and water supplying tank 100, and when the solar heat supply unit 200 cannot provide enough heat, the air energy unit heat supply unit 300 can be used to provide heat for the heat collecting and water supplying tank 100. Thus, the energy consumption required for hot water supply can be greatly reduced, and the cost can be reduced.

[0027] In one embodiment of the utility model, hot water supply system still includes: temperature detection device, temperature detection device is connected with heat supply tank 100, be used for detecting the water temperature in heat supply tank 100, control device, control device is connected with temperature detection device and air energy unit heating unit 300, for based on the detection result of temperature detection device control air energy unit heating unit 300's working condition.

[0028] Further, in one embodiment of the utility model, in the actual water temperature in heat supply tank 100 is greater than or equal to the state of preset water temperature, control closes air energy unit heating unit 300, in the actual water temperature in heat supply tank 100 is less than the state of preset water temperature, control starts air energy unit heating unit 300.

[0029] In one embodiment of the utility model, solar heating unit 200 includes solar heat collecting plate 210, circulating pump 220 and heat exchanger 230. Solar heat collecting plate 210 is connected with heat exchanger 230, heat exchanger 230 is connected with heat supply tank 100, and circulating pump 220 is connected between solar heat collecting plate 210 and heat exchanger 230.

[0031] For example, temperature detection device is temperature sensor, temperature sensor is installed in heat supply tank 100, and it can detect the water temperature in heat supply tank 100 in real time. Solar heat collecting plate 210 absorbs solar radiation and converts light radiation into heat energy to heat heat transfer liquid. Heat transfer liquid has the characteristics of high boiling point and low freezing point, high thermal conductivity. Circulating pump 220 makes heat transfer liquid enter heat exchanger 230 and exchange heat with water in heat supply tank 100, and heat transfer liquid transfers temperature to water through heat exchanger 230.

[0032] When sunlight is more sufficient, solar energy can provide enough heat for heat supply tank 100, in this state, the actual water temperature in heat supply tank 100 is not lower than preset water temperature, and control device can control air energy unit heating unit 300 to stop working. When solar energy cannot meet the heat demand of heat supply tank 100, in this state, the actual water temperature in heat supply tank 100 is lower than preset water temperature, and control device controls air energy unit heating unit 300 to start working to assist the heat gap of solar heating unit 200.

[0033] The air energy unit mainly comprises an evaporator, a compressor, a condenser and an expansion valve. The evaporator absorbs heat from the ambient air, the refrigerant after absorbing heat becomes gaseous, and is pressurized and heated by the compressor, the gaseous refrigerant at high temperature and high pressure enters the condenser, releases heat to water needing to be heated, and is cooled to be liquid. The liquid refrigerant is depressurized and cooled by the expansion valve, and enters the evaporator again to prepare for the next heat absorption process.

[0034] When the air energy unit heating unit 300 is running, the evaporator is used as a heat absorption component, and the surface temperature is usually lower than the dew point temperature of the ambient air, and frost or even ice is easily formed. When the frost / ice reaches a certain degree, the air energy unit heating unit 300 starts the self-cleaning process, that is, the defrosting process, and the specific process is as follows: the frost formation is monitored in real time through the evaporator surface temperature sensor, the ambient temperature sensor and the pressure sensor. When the evaporator temperature difference exceeds the set value, or the running time reaches the preset period of 30-90 minutes, the system determines that defrosting is needed. At this time, the air energy unit heating unit 300 is switched from the heating mode to the refrigeration mode. The compressor increases the rotating speed, and the high-temperature and high-pressure gaseous refrigerant is transported to the evaporator. The high-temperature refrigerant flows through the evaporator copper pipe, releases heat to melt the frost layer on the surface. The defrosting time is controlled to be 3-10 minutes, and the defrosting is completed by the evaporator temperature rising or the pressure change.

[0037] For example, the water supplement unit 400 comprises a water source and a water supplement valve. The liquid level detection device is a liquid level sensor. When the liquid level sensor detects that the actual liquid level in the heat collecting water tank 100 is lower than the preset liquid level, the control device controls the water supplement valve to be opened, so that the water source supplements water in the heat collecting water tank 100. When the liquid level sensor detects that the actual liquid level in the heat collecting water tank 100 is not lower than the preset liquid level, the control device controls the water supplement valve to be closed, so as to stop the water supplement operation.
