Abstract

The present application relates to the technical field of air conditioner defrosting, and discloses a control method for air conditioner defrosting. The control method includes: after the air conditioner enters the bypass defrosting mode, obtaining the defrosting attenuation parameter; when the defrosting attenuation parameter meets the defrosting protection condition, reducing the refrigerant flow rate of the defrosting bypass branch. The control method provided by the embodiments of the present disclosure can control and reduce the refrigerant flow rate of the defrosting bypass branch when the air conditioner enters the bypass defrosting mode, so as to reduce the refrigerant flow diverted by the defrosting bypass branch for defrosting. High-temperature refrigerant flow, thereby reducing the adverse effects of the temperature and flow rate of the gaseous return air refrigerant of the compressor caused by excessive refrigerant being used for defrosting, thereby reducing the defrosting of the air conditioner caused by operating the bypass defrosting mode. Frost ability declines over time. The application also discloses a control device for defrosting the air conditioner 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...
