Refrigerant pouring method of air conditioner outdoor unit

The invention provides a refrigerant pouring method of an air conditioner outdoor unit. The air conditioner outdoor unit comprises a compressor (1) and an outdoor unit heat exchanger (5); and the compressor (1) comprises an air suction cavity and an exhausting cavity. The outdoor unit further comprises an air suction cavity and/or an exhausting cavity communicating with the compressor (1) through a communicating pipeline and/or a large valve (3) and a small valve (6) of the outdoor unit heat exchanger (5); and the large valve (3) is used for pouring refrigerants into the exhausting cavity and/or the air suction cavity of the compressor (1). By means of an air conditioner system, the pouring speed of the refrigerants ( especially R32) of the air conditioner system can be effectively increased, and therefore the running and producing efficiency of the air conditioner system is improved; and the pouring precision of the refrigerants (especially R32) of the air conditioner system can also be effectively improved,
