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 form a closed-loop solution circulation system. The self-cleaning control method includes: reducing the speed of the outdoor fan of the air conditioner under heating conditions And increase the speed of the liquid pump, so that the outdoor heat exchanger is frosted; 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; The heat exchanger is heated 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 problem that the normal user experience is affected by the whole longer self-cleaning time due to the fact that thefrosting speed is generally slow in a self-cleaning control mode of an existing air conditioner, and provides a self-cleaning control method for an air conditioner. The air conditioner comprises a refrigerant circulatory system and a solution circulatory system, wherein the solution circulatory system is composed of an indoor solution film, an outdoor solution film, a liquid pump and a liquid storage tank. The self-cleaning control method comprises the steps that under a heating working condition, the rotating speed of an outdoor draught fan of the air conditioner is reduced and the rotating speed of the liquid pump is increased, so that an outdoor heat exchanger frosts; after the outdoor heat exchanger frosts, firstly an electronic expansion valve is closed, and an electromagnetic valve on the low-voltage side of a compressor is closed after preset time; and the outdoor heat exchanger is heated, so that the outdoor heat exchanger defrosts and is cleaned. The self-cleaning control method for the air conditioner can improve the self-cleaning efficiency of the outdoor heat exchanger, and improve 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...
