Abstract

A system for air conditioning at least one partial region of an aircraft includes an air providing device for providing air to be supplied to a region of the aircraft to be ventilated at a desired temperature and pressure. A supply air duct is connected at a first end to the air providing device. A second end of the supply air duct is connected to an air inlet which opens near the floor into the aircraft region to be ventilated. A control device is set up to ensure that the air provided by the air providing device enters the aircraft region to be ventilated via the air inlet at such a speed that the air is distributed near the floor in the aircraft region to be ventilated and rises at heat sources present in the aircraft region to be ventilated.

First claim

1 . A system for air conditioning at least one partial region of an aircraft, comprising:
an air providing device ( 18 ) for providing air to be supplied to a region of the aircraft to be ventilated at a desired temperature and pressure, a supply air duct ( 20 ) which is connected at a first end to the air providing device ( 18 ), an air inlet ( 24 ) which is connected to a second end of the supply air duct ( 20 ) and opens near the floor into the aircraft region to be ventilated, and a control device ( 26 ) which is set up to ensure that the air provided by the air providing device ( 18 ) enters the aircraft region to be ventilated via the air inlet ( 24 ) at such a speed that the air is distributed near the floor in the aircraft region to be ventilated and rises at heat sources present in the aircraft region to be ventilated, and that the air provided by the air providing device ( 18 ) enters the aircraft region to be ventilated via the air inlet ( 24 ) at such a temperature that a desired ambient temperature is set in the aircraft region to be ventilated.

2 . The system according to claim 1 , wherein the control device ( 26 ) is set up to ensure that the air provided by the air providing device ( 18 ) enters the aircraft region to be ventilated via the air inlet ( 24 ) at a speed of 0.1 to 0.5 m/s.

3 . The system according to claim 1 , wherein the air inlet ( 24 ) is arranged in the region of a floor ( 22 ) and/or in a region, near the floor, of a side wall ( 46 ) of the aircraft region to be ventilated.

4 . The system according to claim 1 , further comprising:
a device ( 52 ) for providing auxiliary air to be supplied the region of the aircraft to be ventilated at a desired temperature and pressure, an auxiliary supply air duct ( 50 ) which is connected at a first end to the auxiliary air providing device ( 52 ), and an auxiliary air inlet ( 48 ) which is connected to a second end of the auxiliary supply air duct ( 50 ) and opens into the aircraft region to be ventilated.

5 . The system according to claim 4 , wherein the auxiliary air inlet ( 48 ) is arranged in the region of a side wall ( 46 ) and/or in the region of a ceiling ( 28 ) of the aircraft region to be ventilated.

6 . The system according to claim 4 , further comprising:
an auxiliary control device which is set up to ensure that the auxiliary air provided by the auxiliary air providing device ( 52 ) enters the aircraft region to be ventilated, via an auxiliary air inlet ( 48 ) arranged in the region of a side wall ( 46 ) of the aircraft region to be ventilated, at such a speed that the air is distributed in the aircraft region to be ventilated in the region of a plane defined by the arrangement of the auxiliary air inlet ( 48 ) and rises at heat sources present in the aircraft region to be ventilated, and that the auxiliary air provided by the auxiliary air providing device ( 52 ) enters the aircraft region to be ventilated, via the auxiliary air inlet ( 48 ) arranged in the region of a side wall ( 46 ) of the aircraft region to be ventilated, at such a temperature that a desired ambient temperature is set in the aircraft region to be ventilated.

7 . The system according to claim 4 , further comprising:
an auxiliary control device which is set up to ensure that the auxiliary air provided by the auxiliary air providing device ( 52 ) enters the aircraft region to be ventilated, via an auxiliary air inlet ( 48 ) arranged in the region of a ceiling ( 28 ) of the aircraft region to be ventilated, at a lower speed than the air entering the aircraft region to be ventilated via the air inlet ( 24 ).

8 . The system according to claim 1 , further comprising:
an air outlet ( 30 ), arranged in the region of a ceiling ( 28 ) of the aircraft region to be ventilated, for removing exhaust air from the aircraft region to be ventilated, which air outlet is connected via a connecting duct ( 58 ) to a pressure regulating valve ( 56 ) for setting a desired pressure in the aircraft region to be ventilated.

9 . The system according to claim 8 , wherein the pressure regulating valve ( 56 ) is arranged in a side region of an aircraft fuselage upper shell ( 36 ) or an aircraft fuselage lower shell ( 57 ).

10 . The system according to claim 8 , further comprising:
an exhaust air duct ( 32 ) which is connected to the air outlet ( 30 ), extends at least in sections along the ceiling region of the aircraft region to be ventilated and leads exhaust air from the aircraft region to be ventilated in the direction of an air sink.

11 . The system according to claim 10 , wherein a condensation water protection device ( 42 ) is arranged in the exhaust air duct ( 32 ) and/or in that the exhaust air duct ( 32 ) is configured and arranged in such a way that exhaust air flowing through the exhaust air duct ( 32 ) is brought into thermal contact with heat-generating components ( 44 ) installed in the ceiling region of the aircraft region to be ventilated, in order to remove heat from the heat-generating components ( 44 ).

12 . The system according to claim 1 , further comprising:
a recirculation duct, connected to the air outlet ( 30 ) and/or to a recirculation outlet ( 31 ) formed separately from the air outlet ( 30 ), for returning to the air providing device ( 18 ) exhaust air removed from the aircraft region to be ventilated through the air outlet ( 30 ).

13 . A method for air conditioning at least one partial region of an aircraft, the method comprising:
providing air, to be supplied to a region of the aircraft to be ventilated at a desired temperature and pressure, by means of an air providing device ( 18 ), and leading the air from the air providing device ( 18 ) through a supply air duct ( 20 ) to an air inlet ( 24 ) which opens near the floor into the aircraft region to be ventilated, a control device ( 26 ) ensuring that the air provided by the air providing device ( 18 ) enters the aircraft region to be ventilated via the air inlet ( 24 ) at such a speed that the air is distributed near the floor in the aircraft region to be ventilated and rises at heat sources present in the aircraft region to be ventilated, and that the air provided by the air providing device ( 18 ) enters the aircraft region to be ventilated via the air inlet ( 24 ) at such a temperature that a desired ambient temperature is set in the aircraft region to be ventilated.

14 . The method according to claim 13 , wherein the control device ( 26 ) ensures that the air provided by the air providing device ( 18 ) enters the aircraft region to be ventilated via the air inlet ( 24 ) at a speed of 0.1 to 0.5 m/s.

15 . The method according to claim 13 , wherein the air is blown into the aircraft region to be ventilated through an air inlet ( 24 ) which is arranged in the region of a floor ( 22 ) and/or in a region, near the floor, of a side wall ( 46 ) of the aircraft region to be ventilated.

16 . The method according to claim 13 , further comprising:
providing auxiliary air, to be supplied to the region of the aircraft to be ventilated at a desired temperature and pressure, by means of an auxiliary air providing device ( 52 ), and leading the auxiliary air from the auxiliary air providing device ( 52 ) through an auxiliary supply air duct ( 50 ) to an auxiliary air inlet ( 48 ) which opens into the aircraft region to be ventilated.

17 . The method according to claim 16 , wherein the auxiliary air is blown into the aircraft region to be ventilated via an auxiliary air inlet ( 48 ) arranged in the region of a side wall ( 46 ) and/or in the region of a ceili
