Abstract

The invention belongs to the technical field of air conditioners, aims to solve the problem that by means of a self-cleaning control mode of an existing air conditioner, the frosting speed is generally slow, so that the whole self-cleaning time is long, and the normal experience of a user is influenced, and provides a self-cleaning control method for an air conditioner. The air conditioner comprises a refrigerant circulation system and a solution circulation system which is composed of an indoor solution membrane, an outdoor solution membrane, a liquid pump and a liquid storage tank. The self-cleaning control method comprises the steps that frequency reducing is carried out on a compressor under the heating working condition, reversing is carried out on a four-way valve, frequency raisingis carried out on the compressor, and the voltage of the indoor solution membrane and the voltage of the outdoor solution membrane are raised, so that an indoor heat exchanger is frosted; after the indoor heat exchanger is frosted, an electronic expansion valve is closed, and then an electromagnetic valve at the low pressure side of the compressor is closed after reset time; and the indoor heat exchanger is heated, so that the indoor heat exchanger is subjected to defrosting cleaning. According to the method, the self-cleaning efficiency of the indoor heat exchanger can be improved, and the user experience is 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.
