Abstract

The invention provides an air conditioner outdoor heat exchanger self-cleaning control method, an air conditioner and a computer readable storage medium. The method comprises the following steps thatafter a heating mode works for a first preset time, an initial defrosting mode is entered, after the work of the initial defrosting mode is finished, whether the number of times that the temperature of an outdoor unit coil is not higher than a preset filth blockage temperature threshold value is larger than the preset number of times or not is judged, if yes, the situation that filth blockage exists in the heat exchanger is determined, and an preset self-cleaning operation is executed. The invention further provides the air conditioner applying the method and a computer readable storage mediumfor achieving the method. According to the air conditioner outdoor heat exchanger self-cleaning control method, the air conditioner and the computer readable storage medium, the filth blockage of theoutdoor heat exchanger of the air conditioner can be accurately judged, calculation of the self-cleaning execution time and duration of the outdoor heat exchanger of the air conditioner is more accurate, the better self-cleaning effect of the outdoor heat exchanger is achieved, and the heat exchange effect of the outdoor heat exchanger is improved.

Description

technical field

[0001] The present invention relates to the technical field of air conditioner control, in particular to a self-cleaning control method for an outdoor heat exchanger of an air conditioner, an air conditioner for realizing the method, and a computer-readable storage medium. Background technique

[0002] The air conditioner transfers heat through the indoor / outdoor heat exchanger to achieve room cooling and heating. The heat exchange effect of the heat exchanger directly affects the cooling / heating effect and operating energy consumption of the air conditioner. The external unit of an air conditioner generally includes a cooling / heating system composed of heat exchangers, pipeline components, compressors, and valves, as well as an air duct system and a control system composed of fans, fan blades, and grilles. Among them, the heat exchange of the heat exchanger relies on the air provided by the fan to flow through the heat exchanger for heat exchange. The heat ...
