A multi-split air conditioning system, comprising a first heat exchanging coiled pipe (101), a second heat exchanging coiled pipe (201), and multiple indoor units (3). Refrigerants having different temperatures flow in the first heat exchanging coiled pipe (101) and the second heat exchanging coiled pipe (201); each indoor unit (3) comprises a heat exchanger and an air supply fan (4); the heat exchanger is connected to the first heat exchanging coiled pipe (101) by means of a first refrigerant input pipe (5) and a first refrigerant output pipe (6), so that the refrigerant in the first heat exchanging coiled pipe (101) can flow into the heat exchanger by means of the first refrigerant input pipe (5), and the refrigerant in the heat exchanger can flow into the first heat exchanging coiled pipe (101) by means of the first refrigerant output pipe (6). The first refrigerant input pipe (5) is provided with a first valve element (7), and the first valve element (7) is configured to adjust refrigerant flow of the fir
