AIRCRAFT AIR CONDITIONING SYSTEM AND METHOD OF OPERATING AN AIRCRAFT AIR CONDITIONING SYSTEM
First Claim
1. An aircraft air conditioning system comprising:
- an ambient air supply line having a first end connected to an ambient air inlet and a second end connected to a mixer of the aircraft air conditioning system so as to supply ambient air to the mixer,a first compressor arranged in the ambient air supply line and being adapted to compress the ambient air flowing through the ambient air supply line,a bleed air supply line having a first end connected to an engine or an auxiliary power unit and a second end connected to an aircraft environment, anda bleed air turbine driven by the bleed air flowing through the bleed air supply line and being coupled to the first compressor so as to drive the first compressor.

Abstract
An aircraft air conditioning system comprising an ambient air supply line having a first end connected to an ambient air inlet and a second end connected to a mixer of the aircraft air conditioning system so as to supply ambient air to the mixer. A first compressor is arranged in the ambient air supply line and is adapted to compress the ambient air flowing through the ambient air supply line. A bleed air supply line allows a flow of bleed air bled off from an engine or an auxiliary power unit therethrough. A bleed air turbine is driven by the bleed air flowing through the bleed air supply line and is coupled to the first compressor so as to drive the first compressor.

9. A method of operating an aircraft air conditioning system, the method comprising the steps:
-
guiding a flow of ambient air through an ambient air supply line having a first end connected to an ambient air inlet and a second end connected to a mixer of the aircraft air conditioning system so as to supply ambient air to the mixer, the flow of ambient air being controlled by a shut off valve, compressing the ambient air flowing through the ambient air supply line via a first compressor arranged in the ambient air supply line, guiding a flow of bleed air bled off from an engine or an auxiliary power unit through a bleed air supply line having a first end connected to the engine or the auxiliary power unit and a second end connected to an aircraft environment, and driving a bleed air turbine by the bleed air flowing through the bleed air supply line, the bleed air turbine being coupled to the first compressor so as to drive the first compressor. - View Dependent Claims (10, 11, 12, 13, 14, 15)
