Abstract: An air conditioner control method includes: obtaining a current ambient temperature when the air conditioner is being powered on, and selecting a current operational parameter corresponding to the current ambient temperature from stored optimal operational parameters which are paired with historical ambient temperatures; performing a control process on the air conditioner according to the current operational parameter; wherein a one-to-one correspondence between the historical ambient temperatures and the optimal operational parameters obtained by a process including: obtaining a continuous running time since this start, how many times operational parameters being modified since this start and a ambient temperature since this start as receiving a power-off signal; obtaining an allowed modification times of operational parameters during the running duration, which corresponds to the continuous running time since this start, if the times of the operational parameters being modified obtained is not greater than
