Abstract

The invention relates to the technical field of air conditioner defrosting, and discloses a control method and device for air conditioner defrosting and an air conditioner. The control method comprises the steps of acquiring the outdoor environment temperature, the refrigerant liquid inlet temperature and the refrigerant liquid outlet temperature while the air conditioner runs in a heating mode; and after it is determined that the defrosting entry conditions are met according to the outdoor environment temperature, the refrigerant liquid inlet temperature and the refrigerant liquid outlet temperature, controlling to heat refrigerants flowing through a refrigerant liquid inlet pipeline and a refrigerant liquid outlet pipeline of an outdoor heat exchanger of the air conditioner. According tothe control method in the embodiment, whether the air conditioner meets the defrosting entry conditions or not can be judged according to the outdoor environment temperature, the refrigerant liquid inlet temperature and the refrigerant liquid outlet temperature, and the control precision for controlling air conditioner defrosting is effectively improved; and the adverse effect of frost condensation on the heating performance of the air conditioner is reduced by heating the refrigerants flowing through the refrigerant liquid inlet pipeline and the refrigerant liquid outlet pipeline.

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...
