The invention relates to the technical field of defrosting of air conditioners, and discloses a control method for defrosting of an air conditioner. The control method includes the steps that in the operation of a heating mode of an air conditioner, an outdoor ambient temperature, a refrigerant liquid inlet temperature and a refrigerant liquid outlet temperature are obtained; and after it is confirmed that defrosting entry conditions are met according to the outdoor ambient temperature, the refrigerant liquid inlet temperature and the refrigerant liquid outlet temperature, and refrigerant flowing through a refrigerant liquid inlet pipeline of an outdoor heat exchanger of the air conditioner is controlled to be heated. According to the control method, whether the air conditioner meets the defrosting entry conditions or not can be judged according to the outdoor ambient temperature, the refrigerant liquid inlet temperature and the refrigerant liquid outlet temperature, the control accuracy of controlling the defrosting of the air conditioner is effectively improved; and through the heating operation of the refrigerant flowing through the refrigerant liquid inlet pipeline, and the temperature of the refrigerant flowing into the outdoor heat exchanger can be effectively increased, so that the refrigerant heat is utilized to melt the frost on the outdoor heat exchanger. The invention further discloses a control device for defrosting of 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, the mainstream models of air conditioners are mostly equipped with cooling and cooling dual-mode heat exchange functions. Here, when the air conditioner is in a low-temperature area or in a snowy climate, the user generally adjusts the air conditioner to the heating mode to use the air conditioner to improve the temperature. 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 exchange It is easy to condense a lot of frost on the air conditioner, and when the frost accumulates to a certain...
