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 form a closed-loop solution circulation system. The self-cleaning control method includes: under the cooling condition, the frequency of the compressor is increased, and the air conditioner is turned off. the indoor fan and increase the 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; The indoor heat exchanger is heated so that the indoor heat exchanger can be defrosted and cleaned

Abstract

The invention belongs to the technical field of air conditioners, and aims to solve the problem that the self-cleaning control mode of an existing air conditioner is generally slow in frosting speed,so that the whole self-cleaning time is long, and the normal experience of a user is influenced. In order to solve the problem, the invention provides a self-cleaning control method for an air conditioner. The air conditioner comprises a refrigerant circulation system and a solution circulation system composed of an indoor solution film, an outdoor solution film, a liquid pump and a liquid storagetank; the self-cleaning control method comprises the steps that under the refrigeration working condition, frequency ascending is carried out on a compressor, an indoor fan of the air conditioner isclosed, and the rotating speed of the liquid pump is increased, so that an indoor heat exchanger is frosted; after the indoor heat exchanger is frosted, an electronic expansion valve is closed firstly, and then an electromagnetic valve at the low pressure side of the compressor is closed after a preset time; and the indoor heat exchanger is heated, so that the indoor heat exchanger is subjected todefrosting cleaning. According to the self-cleaning control method for the air conditioner, the self-cleaning efficiency of the indoor heat exchanger can be improved, and the user experience can be improved.

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.
