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 consisting 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 under the heating work conditions, the opening degree of an electronic expansion valve is decreased, the voltage of the indoor solution membrane and the voltage of the outdoor solution membrane are increased, and thus an outdoor heat exchanger is frosted; after the outdoor heat exchanger is frosted, the electronic expansionvalve 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 isimproved.

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...
