DETAILED DESCRIPTION

[0018] like Figure 1 and Figure 2 As shown, an energy storage air source heat pump 20 includes a mounting frame 10, the mounting frame 10 has a first mounting portion 11 and a second mounting portion 12, the first mounting portion 11 is provided with the air source heat pump 20, the second mounting portion 12 is provided with an energy storage battery 30, and a partition 13 is provided between the first mounting portion 11 and the second mounting portion 12; the air source heat pump 20 has a photovoltaic power interface 23 and a mains power interface 24, and the energy storage battery 30 has an energy storage battery 30 expansion interface and an inverter connection interface 32.

[0019] The mounting frame 10 further comprises a bottom plate 14, a first panel 15, a second panel 16, and a third panel 17, wherein the bottom plate 14, the first panel 15, the second panel 16, the third panel 17, and the partition 13 form a first mounting portion 11. The bottom plate 14, the first panel 15, the second panel 16, the third panel 17, and the partition 13 are galvanized steel plates, and the bottom plate 14, the first panel 15, the second panel 16, the third panel 17, and the partition 13 are formed by sheet metal.

[0020] The partition 13 is arranged in the middle of the base plate 14, and the base plate 14 and the partition 13 form a second mounting portion 12. Therefore, since there is no panel to block it, it is convenient for the energy storage battery 30 to dissipate heat and be repaired and installed. Three fixed mounting holes 141 are arranged on both sides of the base plate 14. Two of the fixed mounting holes 141 are located in the first mounting portion 11, and one fixed mounting hole 141 is located in the second mounting portion 12. During installation, the base plate 14 is fixed to the building surface through the three fixed mounting holes 141 on both sides of the base plate 14, and then the energy storage battery 30 is installed on the second mounting portion 12. In this way, the air source heat pump 20 and the energy storage battery 30 are located on the same base plate 14, which is convenient for installation and future maintenance.

[0021] The air source heat pump 20 has a first water outlet 21 and a second water outlet 22 , wherein the first water outlet 21 is connected to a domestic hot water tank, and the second water outlet 22 is connected to a buffer water tank.

[0023] The principle of the utility model is:

[0024] 1. During the day, the photovoltaic panels are used to directly drive the air source heat pump 20. When the photovoltaic panels cannot support the power of the air source heat pump 20, the mains electricity is used;

[0025] 2. When the photovoltaic panel generates excess electricity other than that consumed by the air source heat pump 20, the photovoltaic panel charges the energy storage battery 30;

[0026] 3. After the energy storage battery 30 is fully charged, there is still surplus power, which is charged into the user's existing energy storage or connected to the Internet or converted into AC power through an inverter for use by other electrical appliances;

[0027] 4. When the air source heat pump 20 is in operation, the energy storage battery 30 is used first, and then supplemented with city electricity after it is used up.

[0028] The beneficial effect of the utility model is that the excess electric energy of the air source heat pump is stored for subsequent use, so as to achieve intelligent regulation of electricity consumption and achieve the purpose of high efficiency and energy saving.
