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. The self-cleaning control method comprises the steps that under the heating work conditions, thefrequency of the compressor is increased, the opening degree of an electronic expansion valve is decreased, the rotating speed of an outdoor fan of the air conditioner is decreased, the voltage of anindoor solution membrane and the voltage of an outdoor solution membrane are increased, and thus an outdoor heat exchanger is frosted; after the outdoor heat exchanger is frosted, the electronic expansion valve 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 is improved.

The invention belongs to the technical field of air conditioners, and provides a self-cleaning control method for an air conditioner. The problems of long time of whole self-cleaning and affecting thenormal experience of users due to the fact that a self-cleaning control mode of an existing air conditioner generally frosts slowly are solved. The air conditioner comprises a refrigerant circulationsystem and a solution circulation system, wherein the solution circulation system is composed of an indoor solution film, an outdoor solution film, a liquid pump and a liquid storage box. The self-cleaning control method includes the steps that under a working condition of heating, the frequency of a compressor is improved, the opening of an electronic expansion valve is reduced, and the voltageof the indoor solution film and the voltage of the outdoor solution film are improved, so that an outdoor heat exchanger is frosted; the electronic expansion valve is firstly closed after the outdoorheat exchanger frosts, and then a a solenoid valve on the low pressure side of the compressor is closed after the preset time; and the outdoor heat exchanger is heated, so that the outdoor heat exchanger performs defrosting and cleaning. The self-cleaning control method for the air conditioner can improve the self-cleaning efficiency of the outdoor heat exchanger and enhance the user experience.

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 relatively slow in frosting speed, so that the whole self-cleaning time is long, and the normal experience of a user is influenced. 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, wherein the self-cleaning control method comprises the following steps that the frequency of a compressor is reducedunder the heating working condition, a four-way valve is subjected to reversing, the frequency of the compressor is raised, the opening degree of an electronic expansion valve is reduced, so that thevoltage of an indoor solution film and the voltage of an outdoor solution film are raised, and therefore, an indoor heat exchanger is frosted. After the indoor heat exchanger is frosted, the electronic expansion valve is turned off, an electromagnetic valve at the low pressure side of the compressor is turned off after a preset time, and the indoor heat exchanger is heated, so that the indoor heat exchanger is subjected to defrosting cleaning. According to the self-cleaning control method, the self-cleaning efficiency of the indoor heat exchanger can be improved, and the experience of a useris improved.
