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 that under the condition that an air conditioner enters a reverse circulation defrosting mode, a liquid inlet refrigerant flowing into an indoor heat exchanger is controlled to be heated; and if the outdoor environment temperature in the heating process meets the air supplementing temperature condition, a compressor is controlled to be subjected to air supplementing. According to the control method provided by the embodiment of the invention, when the air conditioner runs the reverse circulation defrosting mode, the liquid inlet refrigerant of the indoor heat exchanger is heated to increase the air return temperature and flow, the compressor is subjected to air supplementing under the condition of determining that the air supplementing temperature condition is met according to the outdoor environment temperature, and therefore the performance state of the air return refrigerant of the compressor is further improved, and the problem that the air conditioner defrosting capacity is reduced along with time dueto running of the reverse circulation defrosting mode is solved. 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...
