Abstract:
1. An aircraft air conditioning system carried by an aircraft, the aircraft air conditioning system comprising: a fresh air line connected to a fresh air inlet disposed in an unpressurized area of the aircraft for supplying unpressurized fresh air from an ambient environment surrounding the aircraft to an air conditioning unit or an area inside the aircraft to be air-conditioned, and a sorption device operatively disposed in the fresh air line between the fresh air inlet and the air conditioning unit or area inside the aircraft to be air-conditioned, the sorption device containing a sorbent for taking up moisture from unpressurized fresh air flowing through the fresh air line from the fresh air inlet, a valve operatively disposed in the fresh air line between the sorption device and the air conditioning unit or area inside the aircraft to be air-conditioned, the valve having an open position that allows flow of fresh air through the fresh air line from the sorption device to the air conditioning unit or area inside the aircraft to be air-conditioned and a closed position that prevents flow of fresh air through the fresh air line from the sorption device to the air conditioning unit or area inside the aircraft to be air-conditioned, the valve switches to the open position when the aircraft is operating on the ground, and the valve switches to the closed position when the aircraft is flying to expose the sorbent contained in the sorption device to ambient pressure surrounding the aircraft via the fresh air inlet while preventing the flow of fresh air through the fresh air line from the sorption device to the air conditioning unit or area inside the aircraft to be air-conditioned for the purpose of regeneration of the sorbent, and a heat source operatively thermally connected to the sorption device, the heat source supplies thermal energy to the sorbent contained in the sorption device when the valve is closed to assist the regeneration of the sorbent.
