Problems solved by technology
However, when the frost on the outdoor heat exchanger is serious but has not yet entered the defrosting mode, the air conditioner receives a shutdown signal. If it is melted, when the machine is turned on for heating next time, the heating effect will be poor due to the accumulated frost layer on the heat exchanger of the outdoor unit, and even the accelerated accumulation of the frost layer will cause the defrosting in the later stage to be unclean, affecting the comfort of the human body and wasting electric energy. In severe cases, it will cause the compressor to start or liquid refrigerant to be sucked into the compressor during operation, causing the compressor to be burned

The present invention provides an air conditioner and its defrosting control method. The air conditioner includes: a blower motor, a centrifugal blade, a power detection module, a current detection module, a temperature detection module, a storage module and a central processing unit. The beneficial effect is: by accurately judging the degree of frosting of the outdoor heat exchanger when the air conditioner receives a shutdown signal, and then judging whether it needs to be defrosted before shutting down, completely avoiding the outdoor heat exchanger running with frost when the air conditioner is turned on for heating next time , improve the heating effect and protect the safe operation of the air conditioner.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner and a defrosting method for the air conditioner. [0002] technical background [0003] At present, when the air conditioner is heating in winter and the outdoor ambient temperature is low, the outdoor heat exchanger will be frosted to varying degrees, so the air conditioner will automatically switch to the defrosting mode after a certain period of time to remove the frost layer on the outdoor heat exchanger. melt away. However, when the frost on the outdoor heat exchanger is serious but has not yet entered the defrosting mode, the air conditioner receives a shutdown signal. If it is melted, when the machine is turned on for heating next time, the heating effect will be poor due to the accumulated frost layer on the heat exchanger of the outdoor unit, and even the accelerated accumulation of the frost layer will cause the defrosting in the later stage ...
