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 temperature of an indoor coil, the temperature of an outdoor coil, and the refrigerant liquid outlet temperature are obtained; and after it is determined that the defrosting entering condition is met according to the temperature of the indoor coil, the temperature of the outdoor coil, and the refrigerant liquid outlet temperature, the air conditioner is controlled to enter into a reverse-cycle defrosting mode, and first heating operation on a refrigerant flowing through a refrigerant liquid outlet pipeline of an outdoor heat exchanger of the air conditioner is executed. According to the control method, the accuracy of control over air conditioner defrosting can be effectively improved through judgement of whether the air conditioner meets the defrosting entering condition or not according to the temperature of the indoor coil, the temperature of the outdoor coil, and the refrigerant liquid outlet temperature; and through the reverse-cycle defrosting mode and the mode of heating the refrigerant flowing through the refrigerant liquid outlet pipeline, the adverse effects of frost condensation on the heating performance of the air conditioner are lowered in an accelerating mode. 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...
