Abstract

The invention relates to the technical field of an air conditioner, and discloses a control method for air supplementing and enthalpy increasing of the air conditioner. The control method comprises the following steps that a refrigerant state parameter of an air supplementing branch is obtained under the condition that the air conditioner is in heating operation and air supplementing is carried out on a compressor; and the heating operation of liquid inlet refrigerant of a liquid-vapor separator is controlled according to the refrigerant state parameter of the air supplementing branch. According to the control method, the compression performance of the compressor can be improved in an air supplementing mode during heating operation of the air conditioner; and the heating operation of the liquid inlet refrigerant of the liquid-vapor separator is adjusted based on the refrigerant state parameter of the air supplementing branch, after heating is directly adjusted, the liquid inlet refrigerant can become gaseous, the temperature and the flow of the refrigerant for air supplementing are diverted, and therefore the air supplementing effect on air supplementing and enthalpy increasing ofthe compressor is effectively improved. The invention further discloses a control device for air supplementing and enthalpy increasing of the air conditioner and the air conditioner.

Description

technical field [0001] The present application relates to the technical field of air-conditioning, for example, to a control method, a control device, and an air-conditioner for supplementing air to increase enthalpy of 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 exchan...
