Title:
AIR CONDITIONER DEFROSTING CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2019/007376
Kind Code:
A1
Abstract:
An air conditioner defrosting control method. An air conditioner has a heating mode and a defrosting mode, activated if a preset trigger condition is satisfied when the air conditioner operates in the heating mode. The control method comprises: continuously detecting a coil temperature of an indoor heat exchanger (S102) when the air conditioner operates in the heating mode (S100); if the preset trigger condition is satisfied (S104), the air conditioner switching from the heating mode to the defrosting mode, and counting a time duration from activating the heating mode to switching to the defrosting mode in a current instance, the time duration being referred to as a heating mode duration Sy (S106); when the air conditioner finishes defrosting (S108), obtaining a time duration of the operation of the defrosting mode of the current instance, the duration being referred to as a defrosting mode duration Sc (S110); and determining, according to the coil temperature, the heating mode duration Sy, and the defrosting mode duration Sc, a dynamic trigger condition for the air conditioner to enter the defrosting mode in a subsequent instance (S112, S113). The control method adjusts a trigger condition for the subsequent instance the air conditioner enters the defrosting mode, enabling the air conditioner to defrost at the most appropriate time, thereby achieving optimal defrosting.
