Abstract

The invention relates to the field of heat exchange of air conditioners, in particular to an air conditioner non-stop defrosting system and method and an air conditioner. A compressor and an indoor heat exchanger in the air conditioner non-stop defrosting system is connected with each other through a heating gas exhaust pipeline and a heating return gas pipeline to form a heating loop, and the compressor and an outdoor heat exchanger are connected with each other through a defrosting gas exhaust pipeline and a defrosting return gas pipeline to form a defrosting loop; and the heating gas exhaust pipeline, the heating return gas pipeline, the defrosting gas exhaust pipeline and the defrosting return gas pipeline penetrate through a heat storage device. The compressor in the technology simultaneously supply heat for the indoor heat exchanger and the outdoor heat exchanger, heating and defrosting are carried out simultaneously. Moreover, the heating gas exhaust pipeline for exhausting gas to the indoor heat exchanger and the defrosting gas exhaust pipeline for exhausting gas to the outdoor heat exchanger pass through the heat storage device, dissipated heat can be absorbed by the heat storage device, and if heat cannot meet requirements, the heating gas exhaust pipeline and the defrosting gas exhaust pipeline are heated by the heat storage device. In addition, the heat storage device further can supply heat for the heating return gas pipeline and the defrosting return gas pipeline, the temperature of return gas is increased, and the heating effect is improved in a defrosting process.

Description

technical field [0001] The invention relates to the field of air conditioner heat exchange, in particular to an air conditioner non-stop defrosting system, an air conditioner non-stop defrosting method and an air conditioner. 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 non-stop defrosting system, an air conditioner non-stop defrosting me...
