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 needs to defrost, control the heating of the refrigerant flowing through the refrigerant outlet pipeline of the outdoor heat exchanger of the air conditioner and control to increase the flow opening of the throttling device of the air conditioner; The air conditioner is controlled to enter the reverse cycle defrosting mode when the outdoor coil temperature, heating times and defrosting time meet the first preset condition. Use the outdoor coil temperature of the outdoor heat exchanger, heating times and heating time to comprehensively judge the timing of the air conditioner entering the reverse cycle defrosting mode, and improve the control accuracy of controlling the air conditioner entering the reverse cycle defrosting mode; The refrigerant heating of the road and the flow opening of the throttling device are increased to improve the frosting condition of the outdoor heat exchanger. 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 technical field of air conditioner defrosting, for example, to a control method and device for air conditioner defrosting, and an air conditioner. Background technique [0002] At present, most of the mainstream models of air conditioners have the heat exchange function of cooling and heating. Increase the temperature of the indoor environment; during the heating process of the air conditioner, the outdoor heat exchanger of the outdoor unit acts as an evaporator that absorbs heat from the outdoor environment. Affected by the temperature and humidity of the outdoor environment, the outdoor heat exchanger It is easy to condense more frost on the heater, and when the frost accumulates to a certain thickness, the heating capacity of the air conditioner will become lower and lower. Therefore, in order to ensure the heating effect and avoid excessive frost condensation, it is necessary to The outdoor heat exchanger is ...
