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, obtaining the indoor air intake temperature of the indoor unit, the indoor coil temperature, and the upper shell temperature of the outdoor heat exchanger; After the temperature of the tube and the temperature of the upper casing are determined to meet the defrosting entry condition, the flow opening of the throttling device of the air conditioner is controlled to be increased. The control method can judge whether the air conditioner satisfies the defrosting entry condition according to the indoor air inlet temperature, the indoor coil temperature and the upper shell temperature of the outdoor heat exchanger, and improve the control accuracy of controlling the air conditioner defrosting; The flow opening of the flow device changes the temperature and pressure of the refrigerant in the refrigerant circulation circuit, so that the refrigerant that finally flows into the outdoor heat exchanger for defrosting can achieve a better defrosting effect. 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...
