Abstract

The present application relates to the technical field of air conditioner defrosting, and discloses a control method for air conditioner defrosting. The control method includes: when the air conditioner enters the bypass defrosting mode, obtaining the defrosting attenuation parameter; if the defrosting attenuation parameter satisfies the heating start condition, then controlling the heating of the outlet liquid refrigerant of the outdoor heat exchanger. The control method provided by the embodiments of the present disclosure can control the heating of the liquid refrigerant of the outdoor heat exchanger when the air conditioner enters the bypass defrosting mode, so that the liquid refrigerant in the liquid refrigerant of the outdoor heat exchanger is heated This will effectively increase the temperature and flow rate of the gaseous refrigerant in the return air refrigerant of the compressor, thereby reducing the problem that the defrosting capacity of the air conditioner decreases over time due to the operation of the bypass defrosting mode. The application also discloses a control device for defrosting the air conditioner and the air conditioner.

Description

Technical field [0001] The present application relates to the field of air conditioning defrosting technology, for example, to a control method for air conditioning defrosting, a control device and an air conditioner. Background [0002] With the development of science and technology, air conditioning as a kind of general public daily life of the necessary electrical equipment, has been from the very beginning of the single cold model gradually developed to be able to have refrigeration, heating and defrosting and other functions of the advanced model, here, for the low temperature area or large wind and snow climate conditions running air conditioning products, inevitably need to face an important problem is the frost problem of the outdoor unit of the air conditioning, the outdoor heat exchanger of the outdoor unit is to play the role of the evaporator that absorbs heat from the outdoor environment. Affected by the temperature and humidity of the outdoor environment in winter,...
