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, aims to solve the problems that by means of a self-cleaning control mode of an existing air conditioner generally, the frosting speedis generally slow, so that the whole self-cleaning time is long, and the normal experience of a user is influenced, and provides a self-cleaning control method for an air conditioner. The air conditioner comprises a refrigerant circulation system and a solution circulation system which is composed of an indoor liquid film, an outdoor liquid film, a liquid pump and a liquid storage box. The self-cleaning control method comprises the steps that under a refrigeration working condition, frequency reducing is carried out on a compressor, and reversing is carried out on a four-way valve; the openingdegree of an electronic expansion valve is reduced, the rotating speed of an outdoor fan of the air conditioner is reduced, and the rotating speed of the liquid pump is improved, so that an outdoor heat exchanger is frosted; after the outdoor heat exchanger is frosted, the electronic expansion valve is closed, and then a solenoid valve at the low-pressure side of the compressor is closed after preset time; and the outdoor heat exchanger is heated, so that the outdoor heat exchanger is defrosted and cleaned. The method can improve the self-cleaning efficiency of the outdoor heat exchanger andimprove 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...
