The invention belongs to the technical field of air conditioners, and provides a self-cleaning control method for an air conditioner to solve the problems that a self-cleaning control mode of an existing air conditioner is generally low in frosting speed, and consequently the whole self-cleaning time is long, and the normal experience of a user is influenced. The air conditioner comprises a refrigerant circulating system and a solution circulating system. The self-cleaning control method comprises the steps: under the working condition of refrigeration, the frequency of a compressor is decreased, and a four-way valve is reversed; the frequency of the compressor is increased, the rotating speed of an outdoor fan of the air conditioner is decreased, the voltage of an indoor solution film andthe voltage of an outdoor solution film are increased, and thus an outdoor heat exchanger is frosted; after the outdoor heat exchanger is frosted, an electronic expansion valve is closed firstly, andthen a solenoid valve on the low-voltage 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 frostingcleaning. 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...
