Abstract

The invention provides an air conditioner defrosting system and method, and the air conditioner defrosting system comprises a compressor; an indoor heat exchanger; the first end of the throttling assembly communicates with the first end of the indoor heat exchanger; the outdoor heat exchange assembly comprises a first heat exchanger and a second heat exchanger which are connected in parallel, and the first end of the first heat exchanger and the first end of the second heat exchanger communicate with the second end of the throttling assembly; the multi-way valve is used for controlling an exhaust port of the compressor, the second end of the first heat exchanger and the second end of the indoor heat exchanger to be communicated and controlling an air return port of the compressor to be communicated with the second end of the second heat exchanger. The outdoor heat exchange assembly is arranged to be matched with the multi-way valve, a high-temperature and high-pressure refrigerant output by the compressor is directly divided to be used for defrosting the outdoor unit, and the defrosting effect is better.

Description

technical field [0001] The present application relates to the technical field of air conditioners, and in particular to a defrosting system and method for an air conditioner. Background technique [0002] The air conditioner mainly adjusts the ambient temperature by cooling or heating. The air conditioner generally adjusts the indoor temperature by cooling and heating. When the air conditioner is heating, the outdoor heat exchanger will have frost. . [0003] In the prior art, generally, the liquid refrigerant condensed on the indoor side is used to heat the outdoor side return air, and the heat is transferred to the outdoor side heat exchanger through the outdoor side return air for defrosting, so as to achieve the purpose of using the return air to defrost, but , the condensed liquid refrigerant has limited heat transfer, resulting in poor defrosting effect of hot return air. SUMMARY OF THE INVENTION [0004] The present application provides a defrosting system and met...
