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 that the temperature of a first indoor coil is obtained under the condition that an air conditioner enters a reverse cycle defrosting mode; if the temperature of the first indoor coil meets a heating opening condition, liquid inlet refrigerant of an indoor heat exchanger is controlled to be heated; and when a heating duration meets a set duration condition, a compressor is controlled for air supplementing. According to the control method, under the condition that the air conditioner runs in the reverse cycle defrosting mode, the liquid inlet refrigerant of the indoor heat exchanger is controlled to be heated according to the temperature of the indoor coil, and air supplementing is carried out on the compressor according to the heating duration; and the temperature and the flow rate of gaseous refrigerant in air return refrigerant of the compressor are improved by utilizing the liquid inlet refrigerant of the heat exchanger in a heating chamber and the air supplementing mode of the compressor so asto solve the problem that the defrosting capacity of the air conditioner decreases with time. 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 for air conditioner defrosting, a control device and an air conditioner. Background technique [0002] With the development of science and technology, air conditioners, as a necessary electrical equipment in the daily life of ordinary people, have gradually developed from the initial single-cooling models to advanced models with more functions such as cooling, heating and defrosting. Here For air-conditioning products that operate in low-temperature areas or in windy and snowy conditions, an important problem that inevitably needs to be faced is the frosting problem of the outdoor unit of the air conditioner. The role of the evaporator that absorbs heat in the environment is affected by the temperature and humidity of the outdoor environment in winter. More frost is likely to condense on the outdoor heat exchanger, and when the frost a...
