Problems solved by technology
[0005] In order to solve the above-mentioned problems in the prior art, that is, in order to solve the problem that the self-cleaning control mode of the existing air conditioner generally has a slow frosting speed, which leads to a long time for the entire self-cleaning and affects the normal experience of the user, the present invention provides A self-cleaning control method for an air conditioner is provided, the air conditioner includes an indoor heat exchanger, an outdoor heat exchanger, a compressor, an electronic expansion valve and a four-way valve, the indoor heat exchanger, an electronic expansion valve, an outdoor heat exchanger The air conditioner also includes an indoor solution membrane, an outdoor solution membrane, a liquid pump and a liquid storage tank. The indoor solution membrane is set on the indoor heat exchanger, and the outdoor solution membrane is set On the outdoor heat exchanger, the indoor solution membrane, the liquid storage tank, the outdoor solution membrane and the liquid pump constitute a closed-loop solution circulation system. Reverse the valve, reduce the opening of the electronic expansion valve, reduce the speed of the outdoor fan of the air conditioner and increase the speed of the liquid pump, so that the outdoor heat exchanger is frosted; after the outdoor heat exchanger is frosted, close the electronic expansion valve first , after the preset time, close the solenoid valve on the low pressure side of the compressor; heat the outdoor heat exchanger, so that the outdoor heat exchanger can be defrosted and cleaned

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 frequency of the compressor and reversing the direction of the four-way valve under cooling conditions; reducing the opening of the electronic expansion valve, reducing the speed of the outdoor fan of the air conditioner and increasing the speed of the liquid pump, so that the outdoor heat exchanger Frosting; after the outdoor heat exchanger is frosted, first close the electronic expansion valve, and then close the solenoid valve on the low-pressure side of the compressor after a preset time; heat the outdoor heat exchanger to defrost and clean the outdoor heat exchanger . The invention can improve the self-cleaning efficiency of the outdoor heat exchanger and improve 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...
