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.
