[0063] The water inlet end of the hot water storage tank is connected to the tap water system.

[0064] The coil device is an air handling unit or an air handling unit and a floor coil.

[0065] As Figure 3-4 shown, the air source heat pump includes a compressor, a fan, an air-cooled heat exchanger, a liquid distributor, a four-way valve, a main electronic expansion valve, an economizer electronic expansion valve, a plate water / fluorine heat exchanger, a filter, an economizer, a liquid storage tank, and a check valve group.

The inlet of the liquid storage tank is connected between the first one-way valve and the fourth one-way valve;

[0068] Connect the first one-way valve to the fourth one-way valve to regulate the flow direction of the refrigerant and prevent the refrigerant from flowing back. At the same time, it can effectively control the refrigerant flow rate, ensure the normal operation of the heat pump system, reduce the system maintenance cost and damage risk, and improve the system efficiency and energy utilization efficiency;

[0069] As a specific implementation method, the liquid storage tank has the functions of storage, gas-liquid separation, filtration, noise elimination, and refrigerant buffering. Storing the liquid component in the refrigerant can reduce the load of the condenser. The liquid component functions as a liquid seal to prevent gas from entering the low-pressure compressor and causing liquid hammer (liquid hammer mainly occurs in piston compressors. Due to the refrigerant liquid or lubricating oil being sucked into the compressor, it causes abnormal impact accidents in the compressor), and prevent excessive accumulation of condensate in the condenser, which reduces the heat transfer area and affects the heat transfer effect of the condenser; it adapts to the demand for the supply amount due to the load change of the evaporator. When the evaporation load increases, the supply amount also increases, and it is supplemented by the stored liquid in the liquid storage tank; when the load decreases, the required liquid volume also decreases, and the excess liquid is stored in the liquid storage tank, which has a certain noise reduction and filtration function.

[0070] When the heating, cooling, electric heating, and energy storage integrated system is in operation in summer, specifically in the summer refrigeration mode, it is turned on through the line controller or the mobile phone APP. As Figure 3 shown, the air source heat pump turns on the refrigeration mode, and cools the indoor through the coil device at the indoor terminal; after reaching the set temperature, the control system controls the air source heat pump to stop running; the control system starts the electric auxiliary heater in the hot water storage tank to heat the water in the hot water storage tank, and stops heating after reaching the set temperature; the excess electric energy converted by the photovoltaic module is stored in the storage battery, or supplied to the electrical equipment. Thus, refrigeration, hot water supply, electricity storage, and power supply are realized, a four-in-one supply;

[0071] When the heating, cooling, electric heating, and energy storage integrated system is in operation in winter, specifically in the winter refrigeration mode, it is turned on through the line controller or the mobile phone APP. As Figure 4As shown, the air source heat pump turns on the heating mode and warms up the indoor environment through the coil device at the indoor terminal. After reaching the set temperature, the control system controls the air source heat pump to stop operating. The control system activates the electric auxiliary heater in the hot water storage tank to heat the water in the hot water storage tank, and stops heating after reaching the set temperature. The excess electric energy converted by the photovoltaic module is stored in the storage battery or supplied to the electrical equipment. Thus, heating, hot water supply, electricity storage, and power supply are achieved, providing four-in-one supply.

[0072] When the heating, cooling, electric heating, and heat storage integrated system is applied without the need for cooling or heating, it is turned on through the wired controller or the mobile phone APP. The control system activates the electric auxiliary heater in the hot water storage tank to heat the water in the hot water storage tank, and stops heating after reaching the set temperature. The excess electric energy converted by the photovoltaic module is stored in the storage battery or supplied to the electrical equipment. Thus, hot water supply, electricity storage, and power supply are achieved, providing three-in-one supply.

[0073] To verify the technical effect of the system described in the embodiments of the present application when accessing the photovoltaic module for energy supply, a comparison is made between the systems with and without the photovoltaic module connected, as shown in Tables 1 and 2:
