The air-conditioning system comprises a dryer (10) comprising a membrane contactor (11) provided with a first channel (11b) for air flow and a second channel (11a) for desiccant flow, which channels are separated through a membrane (11c). The air conditioning system further comprises a humidifier (20) comprising a membrane contactor. The air flow passes in operation the dryer (10) and the humidifier (30) between an inlet (121) and an outlet (122). The dryer (10) comprises a series connection of a heat exchanger (12) and the membrane contactor (11), which heat exchanger couples air flow from the inlet (121) with desiccant flow from a regenerator (40) and in which membrane contactor (11) the thus heat-exchanged air flow and the heat-exchanged desiccant flow are coupled for drying of the airflow.
