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 heating conditions, the frequency of the compressor is increased, The opening of the electronic expansion valve reduces the speed of the outdoor fan of the air conditioner and increases the voltage of the indoor solution membrane and the voltage of the outdoor solution membrane, so that the outdoor heat exchanger is frosted; after the outdoor 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 outdoor heat exchanger, so that the outdoor heat exchanger can be defrosted and cleaned

Abstract

The invention belongs to the technical field of air conditioners, and provides a self-cleaning control method used for an air conditioner. The self-cleaning control method aims to solve the problem that an existing self-cleaning control mode used for an air conditioner is generally slow in frosting speed, consequently, the overall self-cleaning time is long, and normal experience of a user is affected. The air conditioner comprises a refrigerant circulation system and a solution circulation system. The self-cleaning control method comprises the steps that under the heating work conditions, thefrequency of the compressor is increased, the opening degree of an electronic expansion valve is decreased, the rotating speed of an outdoor fan of the air conditioner is decreased, the voltage of anindoor solution membrane and the voltage of an outdoor solution membrane are increased, and thus an outdoor heat exchanger is frosted; after the outdoor heat exchanger is frosted, the electronic expansion valve is closed firstly, and then an electromagnetic valve on the low-pressure side of the compressor is closed after the preset time; and the outdoor heat exchanger is heated, and thus the outdoor heat exchanger is subjected to defrosting cleaning. According to the self-cleaning control method, the self-cleaning efficiency of the outdoor 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. , which is exposed to the outdoors for a long time, making the dust and bacteria from the outside easily adhere to the outdoor unit. Such bacteria and dust will seriously affect the heat exchange efficiency of the air conditioner, increase the energy consumption of the air conditioner, and reduce the service life of the air conditioner. , so it is necessary to clean the air conditioner in time. [0003] In the prior art, the cleaning methods of the air conditioner include manual cleaning and self-cleaning of the air conditioner. It is time-consuming and labor-intensive to use manual cleaning. It is ne...
