An air-conditioning system in particular for aircraft is proposed wherein pressuized, moisture-containing air is conditioned for air-conditioning the cabin. The pressurized air is compressed further in two separate stages, dehumidified in a high-pressure water extraction cycle and subsequently expanded in one or two turbine stages. Depending on the design one can thereby achieve ice-free conditioned air or a high efficiency of the air-conditioning-system, in particular if two turbine stages are provided and the energy gained in the particular turbine stages is utilized regeneratively, distributed over the compressor stages.
