Abstract:
The present invention relates to the technical field of air-conditioning control, and specifically provides a defrosting control method for an air conditioner, which is intended to solve the problem that existing air conditioner defrosting method cannot accurately determine defrosting timing, thereby leading to unclean defrosting or false defrosting. For this purpose, the defrosting control method for an air conditioner of the present invention comprises: obtaining a preset defrosting time T1 of an air conditioner; obtaining an actual interval period T2 of the last defrosting of the air conditioner; obtaining an actual defrosting time T3 of current defrosting of the air conditioner; calculating a difference T4 between T1 and T3; correcting the actual interval period T2 of the last defrosting of the air conditioner according to the difference T4 to determine the shortest interval period T5 of the next defrosting of the air conditioner; and when a defrosting condition is met and a time interval from the last defrosting is greater than or equal to the shortest interval period T5 of the next defrosting of the air conditioner, controlling the air conditioner to enter a defrosting mode. The method of the present invention may dynamically adjust the time interval between two defrosting operations according to actual working conditions to achieve precise defrosting.
