Self-cleaning control method for air conditioner

Abstract

The invention belongs to the technical field of air conditioners, aims to solve the problem that the self-cleaning control method of an existing air conditioner generally has a low frosting speed, consequently, the whole self-cleaning time is long, and the normal experience of a user is affected, and, to this end, provides a self-cleaning control method for an air conditioner. The air conditionerincludes 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 storage tank, the self-cleaning control method includes the steps that under a heating condition, the frequency of a compressor is increased, the opening degree of an electronic expansion valve is decreased, the rotation speed of theliquid pump is increased, and thus an outdoor heat exchanger frosts; after frosting of the outdoor heat exchanger, the electronic expansion valve is closed, and then a solenoid valve on the low-pressure side of the compressor is closed after a preset time; and the outdoor heat exchanger is heated to defrost and clean the outdoor heat exchanger. According to the self-cleaning control method for anair conditioner, 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...
