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: during the heating mode of the air conditioner, acquiring the accumulated running time of the compressor and the temperature of the first outdoor coil; Afterwards, control is performed to heat the refrigerant flowing through the refrigerant inlet pipeline of the outdoor heat exchanger of the air conditioner. The control method can judge whether the air conditioner satisfies the defrosting entry condition according to the obtained cumulative running time of the compressor and the temperature of the outdoor coil, thereby effectively improving the control accuracy of controlling the defrosting of the air conditioner; The heating operation of the refrigerant in the pipeline increases the temperature of the refrigerant flowing into the outdoor heat exchanger, and uses the heat of the refrigerant to melt the frost condensed on 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, 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...
