Abstract: An aircraft air conditioning system includes a cyclone unit positioned proximate to at least one discharger, the unit having an inlet opening, which communicates with a fresh air supply line, an intake opening, through which air is sucked in from the aircraft cabin, and at least one outlet opening, which communicates with the at least one discharger. A first, cyclone flow of only fresh air is produced in the cyclone unit during operation of the aircraft air conditioning system, the first cyclone flow tending to draw cabin air into the cyclone unit via the intake opening for mixture with the fresh air, after which a second cyclone flow of the cabin air and fresh air are expelled through the outlet opening and the at least one discharger.

Abstract: The invention relates to a decompression element for pressure equalization in a cabin of an aircraft, with a decompression element frame, a flap, and a hinge element or at least one bearing element for fitting the flap to the decompression element frame. The hinge element or the bearing element can be produced from a plastics material. A decompression device for decompressing a cabin area includes a decompression device frame, a first opening which enables a flow to take place between a line of an air-conditioning system of the aircraft and the interior space of the decompression device, a second opening which enables a flow to take place between the cabin area and the interior space of the decompression device, and a third opening receiving the decompression element with the flap.

Abstract: The invention relates to an aircraft air conditioning system with at least one fresh air supply line (14) for conveying fresh air into an aircraft cabin, wherein the fresh air is blown out into the aircraft cabin via at least one discharger (48). In order to form the system so as to save weight and costs, a cyclone unit (10) is disposed in the vicinity of the discharger (48), the unit having an inlet opening (12), which communicates with the fresh air supply line (14), an intake opening (28), through which air is sucked in from the aircraft cabin, and at least one outlet opening (24), which communicates with the at least one discharger (48), wherein a cyclone flow is produced in the cyclone unit (10) during operation of the aircraft air conditioning system by means of the fresh air serving as incoming air and further wherein air is sucked in through the intake opening (28) from the aircraft cabin and expelled together with the fresh air through the outlet opening (24).

Abstract: The invention relates to a decompression element for pressure equalisation in a cabin of an aircraft, with a decompression element frame (4), a flap (2) and a hinge element or at least one bearing element (6?) for fitting the flap to the decompression element frame (4). The hinge element or the bearing element (6?) can be produced from a plastics material. A decompression device for decompressing a cabin area comprises a decompression device frame (17), a first opening (19) which enables a flow to take place between a line (16) of an air-conditioning system of the aircraft and the interior space of the decompression device. A second opening (14) of the decompression device enables a flow to take place between the cabin area and the interior space of the decompression device. The decompression element with the flap (2) is disposed at a third opening.

Abstract: A baffle system (14) for use in an air conditioning unit, in particular an aircraft air conditioning unit, comprises a baffle frame (22) that is attachable to an open end (12) of a pipeline (10) of the air conditioning unit and a baffle (16) that defines a flow cross-section of the pipeline (10). A receiving groove (24, 64) is formed on the baffle frame (22) and/or the baffle (16) which extends over only a portion of the circumference of the baffle frame (22) and/or the baffle (16). The baffle (16) is insertable into the receiving groove (24) formed on the baffle frame (22), and/or a first guide web (28) formed on the baffle frame (22) is insertable into the receiving groove (64) formed on the baffle (16).
