Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Example 1, please refer to Figure 1-Figure 4 As shown, the technical solution provided by the present invention is: a method for processing fresh air for heat recovery of air source heat pump air conditioner. This method is applicable to supermarkets and other places. When the air conditioner is running, it not only makes the indoor temperature higher than the outdoor temperature, but also purifies the introduced fresh air. The method is as follows: Figure 2This is an example diagram of the overall system operation provided in an embodiment of the present invention, including a first air cleaner, a first air source heat pump, a second air source heat pump, a second air cleaner, a fan and a wind generator. The fan is used to input fresh air into the room, or output indoor air to the outside. The wind generator is composed of a generator, an energy storage battery and a wind wheel arranged in an air outlet channel. When the indoor air is discharged through the air outlet channel, the generator converts the kinetic energy generated by the wind wheel when the indoor air flows into electrical energy and stores it in the energy storage battery. In this embodiment, serial number 1 is the first gas temperature after the fresh air passes through the first air cleaner; serial number 2 is the second gas temperature after the fresh air is heated by the first air source heat pump; serial number 3 is the third gas temperature after the fresh air is heated by the second air source heat pump and input into the room; wherein the third gas temperature is greater than the second gas temperature, and the second gas temperature is greater than the first gas temperature; It should be specifically explained that, in this embodiment, the fresh air channel that inputs fresh air into the room and the air outlet channel that outputs indoor gas to the outside are two channels that are not connected to each other. Both use fans that can exhaust reversely to input fresh air into the room or output indoor gas to the outside.

[0020] In this embodiment, the method for processing fresh air for heat recovery of air source heat pump air conditioner includes: Step S1, cleaning the fresh air by a first air cleaner; Wherein, the first air cleaner comprises a primary filter, an electrostatic treatment unit and a photocatalytic unit; In this embodiment, step S1 includes the following sub-steps: Step S11, setting a primary filter in the fresh air channel; Among them, the primary filter is used to intercept large particles in the air, such as dust, pollen, insects and suspended impurities, to prevent these substances from entering the subsequent treatment. The grade of the primary filter is usually G4 or F7, mainly for particles with a diameter of more than a few microns; Step S12, removing dust and other impurities in the fresh air through the electrostatic processing unit, and recording the dust accumulation thickness of the static electrode plate within a fixed dust accumulation time; Among them, the electrostatic treatment unit consists of a high-voltage motor, a dust collecting plate and a power supply device, and uses the principle of electrostatic adsorption to remove particulate matter in the air, such as dust, smoke or aerosols; Step S13, if the dust accumulation thickness on the static electrode plate increases nonlinearly within a fixed time period, it is determined that the electrostatic processing unit is working abnormally, and it is determined that the first air cleaner needs to be cleaned; If the dust accumulation thickness on the static electrode plate increases linearly within a fixed time, it is determined that the electrostatic treatment unit is working normally and the next step is entered; Step S14, removing microorganisms in the fresh air through a photocatalytic unit; Step S15, if the microbial index in the fresh air is less than the microbial index threshold, it is determined that the fresh air cleaning is completed, and the process goes to step S2; If the microbial index in the fresh air is greater than or equal to the microbial index threshold, it is determined that the fresh air cleaning is not completed, and the fresh air is input into the first air cleaner for cleaning again; Step S16, when the microbial index in the fresh air is still greater than or equal to the microbial index threshold after multiple cleanings, it is determined that the first air cleaner needs to be cleaned; Specifically, the photocatalytic unit consists of a photocatalytic plate coated with a titanium dioxide catalyst and a UV light source. When fresh air enters the photocatalytic unit, the UV light source converts the microorganisms in the fresh air into water and carbon dioxide to achieve a cleaning effect.
