Abstract

The invention relates to the field of air conditioner heat exchange, in particular to an air conditioner defrosting system and method and an air conditioner. The air conditioner defrosting system mainly comprises a compressor, a heat accumulation device and an outdoor heat exchanger, wherein the compressor is connected with the outdoor heat exchanger through a defrosting exhaust pipeline and a defrosting gas-return pipeline to form a defrosting loop; and both the defrosting exhaust pipeline and the defrosting gas-return pipeline penetrate the heat accumulation device. According to the technology, after being defrosted, a refrigerant flows back into the heat accumulation device to be heated and then flows back into the compressor so as to avoid flowing back into an indoor heat exchanger and reducing the indoor temperature; the defrosting exhaust pipeline for discharging gas into the outdoor heat exchanger passes through the heat accumulation device, heat emitted by the defrosting exhaust pipeline can be absorbed by the heat accumulation device, and the heat accumulation device can heat the defrosting exhaust pipeline when the defrosting exhaust pipeline does not reach a required temperature; and on the other hand, the heat accumulation device can also supply heat to the defrosting gas return pipeline to increase the temperature of return gas and prevent the indoor temperature from being reduced during a defrosting process.

Description

technical field [0001] The invention relates to the field of air-conditioning heat exchange, in particular to an air-conditioning defrosting system, an air-conditioning defrosting method and the air-conditioning. Background technique [0002] Heat pump air conditioners operate in heating mode in low-temperature environments, which often cannot meet the heating capacity requirements of the internal unit. In addition, when operating in a low temperature environment, the heat exchanger of the outdoor unit is seriously frosted, and the frost will increase the wind resistance of the outdoor unit, resulting in a decrease in the heat transfer coefficient of the heat exchanger and further weakening the heating capacity of the heat pump air conditioner. Contents of the invention [0003] (1) Technical problems to be solved [0004] The object of the present invention is to provide an air conditioner defrosting system, an air conditioner defrosting method and an air conditioner, so...
