Defrosting control method, air conditioner and readable storage medium

The invention discloses a defrosting control method, an air conditioner and a readable storage medium, and the method comprises the steps that a first temperature change parameter corresponding to an outdoor heat exchanger and a second temperature change parameter corresponding to the outdoor environment in the heating operation process of the air conditioner are obtained; the first temperature change parameter is corrected according to the second temperature change parameter, and a target temperature change parameter corresponding to the outdoor heat exchanger is obtained; and when the target temperature change parameter meets the starting condition of the defrosting mode, the air conditioner is controlled to run in the defrosting mode. The invention aims to improve the defrosting control accuracy and improve the heating capacity of the air conditioner.
