Abstract

The invention discloses an air conditioner and a defrosting control method for the same. The defrosting control method comprises the following steps of acquiring accumulated running time of a compressor in the air conditioner and working current of the compressor; detecting indoor environmental temperature T1, and detecting tube temperature T2 of an indoor heat exchanger in the air conditioner; after the air conditioner enters a defrosting mode, acquiring defrosting time according to the accumulated running time of the compressor; judging whether the air conditioner is consistent with a defrosting quitting condition or not according to the working current of the compressor, the indoor environmental temperature T1, the tube temperature T2 of the indoor heat exchanger and the defrosting time; if the air conditioner is consistent with the defrosting quitting condition, controlling the air conditioner to quit the defrosting mode. According to the defrosting control method, the air conditioner can timely quit the defrosting mode after being defrosted, a heating effect can be improved, and energy waste can be avoided.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner defrosting control method and an air conditioner. Background technique [0002] In the related art, when the air conditioner defrosts, the defrosting time is usually set based on the worst working condition of the air conditioner, so the defrosting time is longer, which will exceed the actual needs Shorter defrosting time will cause energy waste and affect the heating effect. [0003] Moreover, the conditions for exiting defrosting of the air conditioner are not differentiated for different refrigeration systems. In fact, the conditions for exiting defrosting are different for refrigeration systems with high energy efficiency and refrigeration systems with low energy efficiency, and the required defrosting time is also different. [0004] Therefore, the air conditioner in the related art cannot exit the defrosting in time when the defrosting is comple...
