Document Type and Number:
WIPO Patent Application WO/2020/224502
Kind Code:
A1
Abstract:
A control method and apparatus for air conditioner defrosting, and an air conditioner. The control method comprises: once an air conditioner has completed the execution of a defrosting process, acquiring a power parameter of the air conditioner related to a current heat exchange power; on the basis of the power parameter related to the current heat exchange power, correcting a defrosting interval duration between the current defrosting process and the next defrosting process; and insofar as on the basis of the corrected defrosting interval duration, interval duration conditions are determined to be met, controlling the air conditioner to determine whether to trigger defrosting for the next defrosting process. The control method for air conditioner defrosting is capable of reducing the problems in the prior art in which the starting up of a defrosting function of the air conditioner is limited and the defrosting function may not be promptly triggered due to using a fixed defrosting time interval to control whether to start up the defrosting function of the air conditioner, and thus achieves more precise control of the defrosting function of the air conditioner.
