<p>An air-conditioning system (100) capable of appropriately regulating humidity. The air-conditioning system (100) has indoor units (1-4) jointly performing air conditioning of the same room. A first indoor unit (1) has a first indoor heat exchanger (11) for regulating the temperature in a space. The second indoor unit (2) has a second indoor heat exchanger (21) and a humidifying element (27). The second indoor heat exchanger (21) regulates the temperature in a room. The humidifying element (27) regulates humidity in the space. The air-conditioning system (100) gives priority to the humidity regulation in the space by the humidifying element (27) over the temperature regulation in the room by the second indoor heat exchanger (21).</p>
