Self-cleaning control method for air conditioner

Abstract

The invention belongs to the technical field of air conditioners, and aims at solving the problems of self-cleaning control methods for existing air conditioners that the frosting speed is low generally, thus the whole self-cleaning time is long, and normal experience of users is influenced. To solve the problems, 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. The self-cleaning control method comprises the steps that under a refrigeration condition, the frequency ofa compressor is increased, the opening degree of an electronic expansion valve is reduced, an indoor draught fan of the air conditioner is shut down, the rotary speed of a hydraulic pump is increased,voltage of an indoor solution membrane and voltage of an outdoor solution membrane are increased, and thus an indoor heat exchanger is frosted; after the indoor heat exchanger is frosted, firstly, the electronic expansion valve is closed, and after a preset time is reached, an electromagnetic valve at the low-pressure side of the compressor is closed; the indoor heat exchanger is then heated, andthus frosting cleaning is carried out on the indoor heat exchanger. By means of the self-cleaning control method, the self-cleaning efficiency of the indoor heat exchanger can be improved, and the user experience is promoted.

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.
