Abstract:
A method of air conditioning a pressurized area of an aircraft, the aircraft having a pressure bulkhead between the pressurized area and an unpressurized area of the aircraft, the method comprising:providing a flow of recirculation air from the pressurized area to the unpressurized area; protecting against depressurization of the pressurized area; mixing the flow of recirculation air directly with a flow of cooling air so that a resultant air mixture is formed having a temperature such that ice particles are substantially eliminated, said mixing performed in the unpressurized area of the aircraft; passing the resultant air mixture through an air duct for delivery to the pressurized area of the aircraft; and removing moisture from the resultant air mixture while passing through the air duct prior to delivery to the pressurized area of the aircraft.
