The air conditioner calculates the required condensation duration and the operating frequency of the compressor according to the current indoor temperature, the current indoor humidity and the current pipeline temperature in real time, so as to ensure The condensation effect can achieve the preset effect and wash the dust. At the same time, the working speed and working time of the indoor fan are correspondingly set according to the condensation time, so that the rotation of the indoor fan can cause the resonance of the fins, and the high-frequency vibration is used to separate the dust and stains attached to the fins from the fins. The water flows out of the air conditioner together, which can completely remove dust and stains and complete self-cleaning. The entire self-cleaning process of the air conditioner only needs to run the condensation condensation function, which can effectively save energy and shorten the self-cleaning time, and can dynamically adjust the cleaning time according to the indoor environment, with a high degree of intelligence.

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 aims to solve the problem that the self-cleaning control mode of the existing air conditioners generally has a slow frosting speed, which leads to a long time for the entire self-cleaning and affects the normal experience of users. For this reason, the present invention provides a kind of self-cleaning control method that is used for air conditioner, and air conditioner comprises refrigerant circulation system and the solution circulation system that is made of indoor solution film, outdoor solution film, liquid pump and storage tank, self-cleaning control The method includes: reducing the opening of the electronic expansion valve, turning off the indoor fan of the air conditioner and increasing the speed of the liquid pump under cooling conditions, so that the indoor heat exchanger is frosted; after the indoor heat exchanger is frosted, first shut down The electronic expansion valve closes the solenoid valve on the low-pressure side of the compressor after a preset time; it heats the indoor heat exchanger, so that the indoor heat exchanger can be defrosted and cleaned. The invention can improve the self-cleaning efficiency of the indoor heat exchanger and improve user experience.

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.
