Abstract
An aircraft air conditioning system includes an ambient air line connected to an air conditioning system mixer to supply ambient air, and a cabin exhaust air line connectable to an aircraft cabin for being flown through with cabin exhaust air. An ambient air compressor in the ambient air line compresses ambient air in the ambient air line. A refrigerating apparatus includes a refrigerant circuit and a refrigerant compressor in the circuit. The refrigerant circuit is thermally coupled to the ambient air line to transfer heat from ambient air line air to refrigerant circulating in the circuit before the ambient air is supplied to the mixer. A turbine is coupled to the air compressor. A control device controls the air conditioning system wherein in a first operating state the turbine receives air from the ambient air line, and in a second operating state receives cabin exhaust air.
