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 following steps ofacquiringthe indoor coil temperature, the outdoor coil temperature and the upper shell temperature of an outdoor heat exchanger while an air conditioner runs in a heating mode; and after it is determined thatthe defrosting entry condition is met according to the indoor coil temperature, the outdoor coil temperature and the upper shell temperature, one or twoof an outdoor fan and an indoor fan is / are adjusted to a defrosting operation rotating speed. According to the control method, whether the air conditioner meets the defrosting entry condition or not can be determined according to the indoor coil temperature, the outdoor coil temperature and the upper shell temperature of the outdoor heat exchanger, so that the control precision for controlling air conditioner defrosting is improved; and the heat exchange rates of the corresponding heat exchangers and the external environment are changed by adjusting the rotating speeds of the indoor fan and the outdoor fan, so that the aggravating influenceof the temperature environment on the frosting degree of the outdoor heat exchanger is reduced. The invention also 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...
