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 operation of the air conditioner in the heating mode, obtaining the refrigerant outlet temperature, outdoor coil temperature and upper shell temperature of the outdoor heat exchanger; And after it is determined that the temperature of the upper shell satisfies the defrosting entry condition, the control enters the reverse cycle defrosting mode and performs the first heating operation for the refrigerant flowing through the refrigerant outlet pipeline of the outdoor heat exchanger. The control method judges whether the air conditioner meets the defrosting entry condition according to the refrigerant outlet temperature of the outdoor heat exchanger, the temperature of the outdoor coil and the temperature of the upper shell, so as to improve the control accuracy of controlling the defrosting of the air conditioner; The mode and the method of heating the refrigerant flowing through the refrigerant outlet pipeline can accelerate the reduction of the adverse effect of frost condensation on the performance of the air conditioner. The application also discloses a control device for defrosting an air conditioner and an 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, most of the mainstream models of air conditioners have the heat exchange function of cooling and cooling dual-mode. Here, users generally adjust the air conditioner to the heating mode in low temperature areas or under climatic conditions with heavy wind and snow, so as to use the air conditioner to improve The temperature of the indoor environment; during the heating process of the air conditioner, the outdoor heat exchanger of the outdoor unit plays the role of an evaporator that absorbs heat from the outdoor environment, and is affected by the temperature and humidity of the outdoor environment. It is easy to condense more frost on the appliance, and when the combined frost reaches a certain thickness, the heating capacity of...
