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 a firstcurrent liquid inlet temperature and a first current liquid outlet temperature of an outdoor heat exchanger of an air conditioner are acquired in the condition that the air conditioner enters a bypass defrosting mode; and if the first current liquid inlet temperature and a first current refrigerant liquid outlet temperature meet a refrigerant temperature condition, a liquid inlet refrigerant of the outdoor heat exchanger is controlled to be heated. According to the control method, under the condition that the air conditioner enters the bypass defrosting mode, the liquid inlet refrigerant of the outdoor heat exchanger is heated according to the difference condition of the liquid inlet temperature and the liquid outlet temperature of the outdoor heat exchanger, so that the refrigerant flowing into the outdoor heat exchanger can be heated to a higher temperature, and the problem that the defrosting capacity of the air conditioner is reduced over time due to the operation of the bypass defrosting mode is reduced. The invention further discloses a control device for air conditioner defrosting and an 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...
