Abstract

The invention provides an air conditioner defrosting control method and device and an air conditioner. The air conditioner comprises a compressor, an outdoor heat exchanger, an indoor heat exchanger, a gas pipeline and a liquid pipeline, the air conditioner further comprises a defrosting pipeline, one end of the defrosting pipeline communicates with the gas pipeline, and the other end of the defrosting pipeline is connected to the outdoor heat exchanger. Whether the air conditioner meets the defrosting condition or not is judged; and if yes, the high-temperature refrigerant in the compressor is controlled to flow to the indoor heat exchanger from the gas pipeline, and meanwhile the high-temperature refrigerant in the compressor is controlled to flow to the outdoor heat exchanger from the defrosting pipeline. The technical problems that when the air conditioner conducts heating and defrosting, the heating efficiency of the air conditioner is low, and the user experience is poor can be solved.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, and in particular, to an air conditioner defrosting control method, a control device, and an air conditioner. Background technique [0002] During the heating operation of the air conditioner, if the outdoor ambient temperature is low, frost will form on the fins of the outdoor heat exchanger. Normally, when defrosting the fins of the outdoor heat exchanger, the indoor fan will stop rotating. At this time, the heat exchange efficiency of the indoor heat exchanger is low, which will cause the room temperature to fluctuate greatly, thereby reducing the user experience. [0003] In the related art, there are shortcomings: when the air conditioner is heating and defrosting, the heating efficiency of the air conditioner is reduced, which further reduces the user's experience. SUMMARY OF THE INVENTION [0004] The invention can solve the technical problems of low heating efficiency ...
