A1
Abstract:
A defrosting control method for an air conditioning unit. The air conditioning unit comprises an outdoor unit. The defrosting control method comprises: obtaining the outdoor dry-bulb temperature and the outdoor wet-bulb temperature, and the outdoor tube temperature, the evaporation pressure, and a present operation duration of the air conditioning unit; determining the current air outlet volume of the outdoor unit according to the outdoor dry-bulb temperature, the outdoor wet-bulb temperature, the outdoor tube temperature, the evaporation pressure, and the present operation duration; and according to the current air outlet volume of the outdoor unit, selectively controlling the air conditioning unit to enter an outdoor unit defrosting mode. The defrosting control method can accurately determine the optimal entering timing of the defrosting mode, and thus effectively ensuring that the air conditioning unit can maintain the efficient operation state for a long time.
