摘要： Disclosed is a multi-split air conditioner capable of refrigerating and heating simultaneously. A heating circuit consists of a compressor (1), an oil-gas separator (2), a four-way valve (3), indoor heat exchanging systems (12,16,21,22), an outdoor heat exchanger (7), a four-way valve (3), and a gas-liquid separator (26) connected in series along the refrigerant flow direction. A refrigerating circuit consist of a compressor (1), an oil-gas separator (2), a four-way valve (3), an outdoor heat exchanger (7), indoor heat exchanging systems (12,16,21,22), and a gas-liquid separator (26) connected in series along the refrigerant flow direction. A parallel pipeline is arranged at a pipeline between the outdoor heat exchanger (7) and the indoor heat exchanging systems (12,16,21,22), and is utilized for connecting an second electronic expansion valve (8) with a second one-way valve (9) in parallel. A series pipeline is arranged with a third control valve (5) and a third one-way valve (6). An end of the series pipeline is connected to the pipeline between the four-way valve (3) and the outdoor heat exchanger (7), and another end of the series pipeline is connected to the pipeline between a first one-way valve (4) and the indoor exchanging systems (12,16,21,22). Five operation modes, i.e. single refrigerating, single heating, mainly refrigerating, mainly heating, simultaneous refrigerating and heating, can be realized in the multi-split air conditioner capable of refrigerating and heating simultaneously.
