Beschreibung
Zusammenfassung:	An aircraft air conditioning system includes an ambient air line connected to an aircraft air conditioning system mixer to supply ambient air, and a cabin exhaust air line connectable to an aircraft cabin, and a bleed air line drawn off from an engine or auxiliary power unit. An ambient air compressor in the ambient air line compresses ambient air. A refrigerating apparatus includes a refrigerant circuit and a refrigerant compressor. The refrigerant circuit is thermally coupled to the air line to transfer heat from air line air to refrigerant circulating in the refrigerant circuit before the air is supplied to the mixer. A turbine is coupled to the air compressor. A control device controls the aircraft air conditioning system wherein in a first operating state the turbine receives air from the air line, and in a second operating state receives a mixture of bleed air and cabin exhaust air.
