Abstract

The invention relates to the technical field of air conditioner defrosting, and discloses a control method for air conditioner defrosting. The control method comprises the steps: in the process that an air conditioner operates in a heating mode, the outdoor air outlet temperature, the refrigerant liquid inlet temperature and the refrigerant liquid outlet temperature of an outdoor unit are obtained; and after it is determined that the defrosting entry condition is met according to the outdoor air outlet temperature, the refrigerant liquid inlet temperature and the refrigerant liquid outlet temperature, a refrigerant flowing through a refrigerant liquid inlet pipeline and a refrigerant liquid outlet pipeline of an outdoor heat exchanger of the air conditioner is controlled to be heated. According to the control method provided by the embodiment of the invention, whether the air conditioner meets the defrosting entry condition or not can be judged according to the outdoor air outlet temperature, the refrigerant liquid inlet temperature and the refrigerant liquid outlet temperature, and the precision of control over air conditioner defrosting is effectively improved; and by heating therefrigerant flowing through the refrigerant liquid inlet pipeline and the refrigerant liquid outlet pipeline, the adverse impact of frost condensation on the heating performance of the air conditioner is lowered. The invention further discloses a control device for air conditioner defrosting, 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...
