Air conditioning system

The invention provides an air conditioning system. The air conditioning system comprises a compressor, a condenser and a throttling device which are sequentially connected. The condenser comprises a plurality of condenser pipeline sections communicated in sequence. A first steam-liquid separation device is communicated between every two condenser pipeline sections. A refrigerant inlet pipe of each first steam-liquid separation device is communicated with the condenser pipeline section located on the upstream of the refrigerant inlet pipe and adjacent to the refrigerant inlet pipe in the refrigerant flow direction. A steam outlet of each first steam-liquid separation device is communicated with the adjacent condenser pipeline section on the downstream of the refrigerant flow direction. Liquid outlets of the first steam-liquid separation devices are communicated with the throttling device. By means of the air conditioning system, the problem that in the prior art, a condenser in an air conditioning system is poor in heat exchange performance is effectively solved.
