The invention discloses a defrosting control device and method of an air conditioner and the air conditioner. The device comprises an acquiring unit and a control unit, wherein the acquiring unit is configured to acquire the air inlet temperature, the air inlet humidity, the air outlet temperature and the air outlet humidity of the air conditioner; and the control unit is configured to determine the frosting amount of an evaporator of the air conditioner according to the air inlet temperature, the air inlet humidity, the air outlet temperature and the air outlet humidity, determine whether theair conditioner needs defrosting or not according to the air inlet temperature, the air outlet temperature and the frosting amount, control the air conditioner to enter the defrosting mode under thecondition that the air conditioner needs defrosting, and control the defrosting time of the air conditioner under the defrosting mode. According to the technical scheme, the judgment logic for the defrosting entering condition and the defrosting quitting condition during hot air bypass defrosting is intelligentized, so that different working conditions are adapted.

    本发明公开了一种空调的化霜控制装置、方法和空调,该装置包括:获取单元和控制单元;其中,所述获取单元,被配置为获取所述空调的进风温度、进风湿度、出风温度和出风湿度;所述控制单元,被配置为根据所述进风温度、所述进风湿度、所述出风温度和所述出风湿度,确定所述空调的蒸发器的结霜量;根据所述进风温度、所述出风温度和所述结霜量,确定所述空调是否需要进行化霜;以及,在所述空调需要进行化霜的情况下,控制所述空调进入化霜模式,并控制所述空调在所述化霜模式下的化霜时间。该方案,通过使热气旁通化霜时化霜的进入条件和退出条件的判断逻辑智能化,以适应不同工况。
