Problems solved by technology

[0002] At present, in order to improve the low-temperature heating capacity and heating performance coefficient of air conditioners, some air conditioners adopt the technology of air injection enthalpy increase, especially some multi-connected air conditioners, which use air injection enthalpy increase compressors, and add air injection enthalpy increase technology to the system. Enthalpy loop, but the energy efficiency of the system is still relatively low in the cooling mode of the air conditioner based on the jet enthalpy technology

Abstract

The invention discloses an air conditioner. The air conditioner comprises an enhanced vapor injection compressor, a condenser, a vapor-liquid separation header, a subcooler, an electronic expansion valve and high-pressure stop valves, wherein a first port of the vapor-liquid separation header is connected with a first refrigerant feed and discharge port of the condenser; a second port of the vapor-liquid separation header is connected to a first refrigerant feed and discharge port of the subcooler through the electronic expansion valve; a third port of the vapor-liquid separation header is connected with a second refrigerant feed and discharge port of the subcooler; a third refrigerant feed and discharge port of the subcooler is connected with the high-pressure stop valves; a fourth refrigerant feed and discharge port of the subcooler is connected to a suction port of the enhanced vapor injection compressor. The invention further discloses an air conditioner refrigerant adjusting method and device. The refrigerating capacity of the air conditioner based on enhanced vapor injection technology is improved.
