Abstract

The invention relates to the technical field of air conditioner defrosting, and discloses a control method for air conditioner defrosting. The control method for air conditioner defrosting comprises the steps that an indoor air inlet temperature, an indoor coil temperature and an upper shell temperature of an outdoor heat exchanger during operation of a heating mode of an air conditioner are obtained; and after it is determined that the defrosting entering condition is met according to the indoor air inlet temperature, the indoor coil temperature and the upper shell temperature, one or both ofan outdoor fan and an indoor fan of an air conditioner is adjusted to a corresponding defrosting operation speed. According to the control method for air conditioner defrosting, the indoor air inlettemperature, the indoor coil temperature and the upper shell temperature of an outdoor heat exchanger are used for judging whether the air conditioner meets the defrosting entering condition or not, and the control precision of controlling the air conditioner defrosting can be improved; through the adjustment operation of the rotational speed of the indoor fan and the outdoor fan, the increased influence of the temperature environment on the degree of frosting of the outdoor heat exchanger is reduced. The invention further provides 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...
