Background
At present, a large amount of domestic hot water at about 50 ℃ is needed in places such as schools, hotels and factories, and solar water heaters are widely used in the places due to long average solar irradiation time of solar energy in China and rich solar energy resources. In addition, because the annual average air temperature of large areas in China is higher, for example, the average air temperature in south China (Guangdong, guangxi, guizhou, yunnan, hainan and the like) is higher than 22 ℃, the air energy heat pump is also used in a large quantity, and is used as an auxiliary heating system of solar hot water, the two systems are well combined together, so that the annual hot water supply of users can be ensured, and meanwhile, compared with the fuel gas, fuel oil and electric heating water heating cost, the air energy heat pump is lower, and the air energy heat pump is more energy-saving and environment-friendly.
However, the combination of solar energy and an air source heat pump has the following problems, and the problems need to be further optimized and solved:
1. in the use process of the solar water heater, when the sunlight intensity is not strong, the photo-thermal energy can only heat the water temperature to the warm water degree, for example, the water temperature can not be increased any more at about 30-40 ℃, and at the moment, warm water users can not directly use the solar water heater; in addition, because the number of the common solar heat collectors is large when the solar heat collector is installed on engineering, the large scale causes large warm water quantity, and the air energy heat pump heat source is air, the part of warm water heat energy cannot be used at the moment, so that the part of heat energy is wasted, and the part of heat energy is very unfortunately;
2. in the use process of the air source heat pump, the evaporator is in direct contact with air for a long time, so that dust is easy to adhere to the evaporator, the heat transfer effect is greatly affected, the heating coefficient of the air source heat pump is reduced, and the hot water cost of a user is increased.
The water source heat pump has better heat transfer effect, higher heat transfer density and higher heating coefficient than the air source heat pump, so that the water source heat pump is more energy-saving, but the water source heat pump generally requires a large amount of water sources such as rivers, lakes, ponds and the like, so that heat energy can be continuously provided, and the general places hardly reach the conditions, so that the water source heat pump is more energy-saving than the air source heat pump, but is greatly limited by the water source and the installation place during installation.

(3) solar direct heating: when the hot water tank 22 does not reach the full water level, the water source in the intermediate water tank 6 supplements water for the solar heat collector through the water feeding pump I7, and after the water supplement is completed, (the water supplement is completed when the temperature measured by the temperature sensor III 28 is equal to the temperature measured by the temperature sensor I15, and at the moment, the water feeding pump I7 is stopped, the reverse return valve I8 prevents backflow, and the solar heat collector is ensured to be full water level). When the temperature sensor I15 detects that the water temperature reaches a set value, the electromagnetic valve II 17 is closed, the electromagnetic valve I16 is opened, and finished hot water enters a hot water tank;
(4) solar energy cyclic heating: when the liquid level meets a set value, and when the temperature difference measured by the temperature sensor I15 and the temperature sensor II 24 is more than or equal to 2 ℃, the hot water circulating pump 1 starts to be started, the electromagnetic valve II 17 is closed, the water feeding pump I7 is stopped, the electromagnetic valve I16 is opened, hot water in the solar heat collector enters the hot water tank, the water replenishing of the solar heat collector is supplemented by a water source in the hot water tank 22, and the hot water in the hot water tank and the solar heat collector 10 are circularly heated, so that overflow of the hot water tank is avoided.
