Abstract

The invention discloses an air conditioner as well as a control method and device and belongs to the technical field of air conditioner defrosting. The air conditioner comprises a heat regenerating device; the heat regenerating device comprises a first heat exchange part and a second heat exchange part which can be used for heat exchange; the first heat exchange part is connected to a first refrigerant pipeline between an indoor heat exchanger and an outdoor heat exchanger; and the second heat exchange part is connected to an air return pipeline of a compressor. According to the air conditioner disclosed by the invention, the heat regenerating device is additionally arranged in an air conditioner pipeline, and the defrosting opening of a throttling device can be regulated according to the air return temperature of the compressor under the condition that a liquid refrigerant flows back to the compressor because the liquid inlet temperature of the outdoor heat exchanger is lower than an outdoor dew point temperature, so that the refrigerant flowing into the outdoor heat exchanger through the throttling device is adapted with the current defrosting condition; and the liquid refrigerant flowing back to the compressor is heated and vaporized by virtue of the heat regenerating device, so that the quantity of the refrigerant condensed into a liquid when flowing through the outdoor heat exchanger is reduced, and the safe and effective operation of the whole of the compressor and the air conditioner is guaranteed.

Description

technical field [0001] The invention relates to the technical field of air conditioner defrosting, in particular to an air conditioner, a control method and a control device. Background technique [0002] When air-conditioning products are operated in severe cold weather conditions in winter, outdoor water vapor or ice and snow will condense on the surface of the outdoor heat exchanger, and then form a frost layer on the outer surface of the outdoor heat exchanger, which will make the outdoor heat exchanger contact with the outside world. The environment is isolated, reducing the amount of heat exchange between the refrigerant in the outdoor heat exchanger and the external environment, which affects the heating performance of the air conditioner. [0003] Therefore, some air-conditioning products are equipped with the function of defrosting the outdoor heat exchanger. There are two main ways for the existing air-conditioning property rights to defrost the outdoor unit: one i...
