The invention belongs to the technical field of air conditioners, and aims to solve the problem that the self-cleaning control mode of an existing air conditioner is generally slow in frosting speed,so that the whole self-cleaning time is long, and the normal experience of a user is influenced; In order to solve the problem, 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 following steps that under the refrigeration working condition, frequency reducing is carried out on a compressor, and a four-way valve is reversed; the rotating speed of an outdoor fan of the air conditioner is reduced, and the voltage of an indoorsolution film and the voltage of an outdoor solution film are risen, so that an outdoor heat exchanger is frosted; after the outdoor heat exchanger is frosted, an electronic expansion valve is closedfirstly, and then an electromagnetic valve at the low pressure side of a compressor is closed after a preset time; and the outdoor heat exchanger is heated, so that the outdoor heat exchanger is subjected to defrosting cleaning. According to the self-cleaning control method for the air conditioner, the self-cleaning efficiency of the outdoor heat exchanger can be improved, and the user experiencecan be 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...
