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 of acquiring an indoorair inlet temperature, an indoor coil temperature and an upper shell temperature of an outdoor heat exchanger during the running and heating mode of the air conditioner; controlling the heating of the refrigerant flowing through a refrigerant liquid inlet pipe of an outdoor heat exchanger of the air conditioner after determining meeting the defrosting entry condition according to the indoor air inlet temperature, the indoor coil temperature and the upper shell temperature. The control method provided by the invention can determine whether the air conditioner meets 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, the control precision of the defrosting control air conditioner is improved effectively; the heating operation of the refrigerant flowing through the refrigerant liquid inlet pipe is performed, so the temperature of the refrigerant flowing into the outdoor heat exchanger is improved, and then the condensed frost is molten by the refrigerant heat. The invention further discloses a control device and an air conditioner for air conditioner defrosting.

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...
