Self-cleaning control method for air conditioner

Abstract

The invention belongs to the technical field of air conditioners and aims to solve the problem that the self-cleaning control mode of the existing air conditioners generally has a slow frosting speed, which leads to a long time for the entire self-cleaning and affects the normal experience of users. For this reason, the present invention provides a kind of self-cleaning control method that is used for air conditioner, and air conditioner comprises refrigerant circulation system and the solution circulation system that is made of indoor solution film, outdoor solution film, liquid pump and storage tank, self-cleaning control The method includes: reducing the opening of the electronic expansion valve, turning off the indoor fan of the air conditioner and increasing the speed of the liquid pump under cooling conditions, so that the indoor heat exchanger is frosted; after the indoor heat exchanger is frosted, first shut down The electronic expansion valve closes the solenoid valve on the low-pressure side of the compressor after a preset time; it heats the indoor heat exchanger, so that the indoor heat exchanger can be defrosted and cleaned. The invention can improve the self-cleaning efficiency of the indoor heat exchanger and improve user experience.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and specifically provides a self-cleaning control method for an air conditioner. Background technique [0002] The air conditioner is a device that can cool / heat the room. As time goes by, the dust accumulation on the indoor and outdoor units of the air conditioner will gradually increase. After the dust accumulation reaches a certain level, a large number of bacteria will grow, especially in the indoor When the air flows through the indoor unit, it will carry a lot of dust and bacteria, which will seriously affect the heat exchange efficiency of the air conditioner, increase the energy consumption of the air conditioner, and re-distribute the bacteria and bacteria along with the air flow. Dust is brought into the room, which will cause harm to the human body and easily cause people to suffer from respiratory diseases. Therefore, it is necessary to clean the air conditioner in time.

Problems solved by technology

[0005] In order to solve the above-mentioned problems in the prior art, that is, in order to solve the problem that the self-cleaning control mode of the existing air conditioner generally has a slow frosting speed, which leads to a long time for the entire self-cleaning and affects the normal experience of the user, the present invention provides A self-cleaning control method for an air conditioner is provided, the air conditioner includes an indoor heat exchanger, an outdoor heat exchanger, a compressor, an electronic expansion valve and a four-way valve, the indoor heat exchanger, an electronic expansion valve, an outdoor heat exchanger The air conditioner also includes an indoor solution membrane, an outdoor solution membrane, a liquid pump and a liquid storage tank. The indoor solution membrane is set on the indoor heat exchanger, and the outdoor solution membrane is set On the outdoor heat exchanger, the indoor solution membrane, the liquid storage tank, the outdoor solution membrane and the liquid pump constitute a closed-loop solution circulation system. The self-cleaning control method includes: reducing the opening of the electronic expansion valve, closing the The indoor fan of the air conditioner increases the rotation speed of the liquid pump, so that the indoor heat exchanger is frosted; after the indoor heat exchanger is frosted, first close the electronic expansion valve, and then close the solenoid valve on the low-pressure side of the compressor after a preset time ;Heat the indoor heat exchanger, so that the indoor heat exchanger can be defrosted and cleaned
