Air conditioner control method and device, air conditioner and storage medium

The invention provides an air conditioner control method and device, an air conditioner and a storage medium. The method comprises the steps that air conditioner working condition parameters of the air conditioner and the air conditioner operation frequency corresponding to the air conditioner working condition parameters are obtained; according to the cooling rate corresponding to the air conditioner operation frequency and a preset frequency adjustment coefficient, correction learning is conducted on the air conditioner operation frequency, and the corrected operation frequency of the air conditioner working condition parameters is obtained; predicting a predicted temperature difference of a target time period according to a temperature difference prediction model of the corrected operation frequency, and adjusting the corrected operation frequency according to the predicted temperature difference and a preset standard temperature difference to obtain a target operation frequency; and the operation state of
