The invention belongs to the technical field of air conditioners, and provides a self-cleaning control method for the air conditioner. The method aims to solve the problems that in general, an existing self-cleaning control mode of the air conditioner is low in frosting speed, so that the whole self-cleaning time is long, and the normal experience of a user is influenced. The air conditioner comprises a cold medium circulation system and a solution circulation system formed by an indoor solution film, an outdoor solution film, a liquid pump and a liquid storage box; and the self-cleaning control method comprises the following steps that under a refrigeration working condition, the frequency of a compressor is reduced and a four-way valve is reversed; the frequency of the compressor is raised and the rotating speed of the liquid pump is raised so as to frosting an outdoor heat exchanger; after the outdoor heat exchanger is frosted, an electronic expansion valve is closed firstly, and then a solenoid valve on the low-pressure side of the compressor is closed after a preset period of time; and the outdoor heat exchanger is heated so as to defrosting and cleaning the outdoor heat exchanger. The method can improve the efficiency of self-cleaning on the outdoor heat exchanger and improve the user experience.
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...
