摘要:
Method for controlling the temperature of feed air injected into at least one cabin zone of a passenger aircraft, the temperature of injected feed air being controlled for each cabin zone dependent on the deviation of the injection temperature actual value of the feed air from an injection temperature target value, the injection temperature target value being established using an external ambient temperature actual value and not using a temperature sensor in the at least one cabin zone.

A method and a line system for the air-conditioning of a cabin of an aircraft envisage that at sites remote from passengers air that is at a temperature lower than air at sites closer to passengers is introduced into the cabin.

A system for improving the air quality in a pressure cabin of an aircraft comprises a recirculation air circuit by means of which a portion of the cabin air, referred to as recirculation air, is withdrawn from the pressure cabin, filtered and then recirculated into the pressure cabin. To increase the oxygen partial pressure of the air fed back into the pressure cabin, the quantity of recirculation air is passed wholly or partially through a nitrogen generator (52) which generates nitrogen and an oxygen-containing waste gas from the recirculation air supplied. The oxygen-containing waste gas of the nitrogen generator (52), together with any remaining quantity of recirculation air untreated by the nitrogen generator (52), is recirculated into the pressure cabin. The nitrogen generator (52), to which only recirculation air is supplied, utilises a pressure gradient existing in flight between the pressure cabin and the outside of the aircraft for nitrogen generation.

The present application describes an arrangement and a method for utilizing the heat of waste air for heating the bilge area of aircraft, wherein the bilge area is connected to a heat transfer unit via a first air supply pipe, through which a bilge air flow drawn in from the bilge area flows into the heat transfer unit, wherein the heat transfer unit comprises a second air supply pipe, through which a waste air heat flow to be cooled that is created at another location in the aircraft flows into the heat transfer unit in order to heat the drawn-in bilge air flow, wherein the heat transfer unit comprises a first air discharge pipe, through which the cooled waste air heat flow is discharged, and a second air discharge pipe with a bilge inlet section, and wherein at least a portion of the heated bilge flow is returned to the bilge area via the air discharge pipe and the bilge inlet section.
摘要:
An air supply system for an aircraft cabin reduces the concentration of contaminations of the air in the cabin by a flexibly controllable valve system that comprises pairs of valves which on the one hand are ganged to respective air openings. One valve of a pair is connected to a fresh air or mixed air supply line. The other valve of a pair is connected to a suction or exhaust duct. Thus, depending on which valve in a pair is open and which is closed, the respective air opening can function as an air outlet for supply of mixed or fresh air into the cabin or as a suction port. Such a system permits a flexible volume control of the supply of fresh air into selectable cabin sections as well as a flexible volume control for the removal of used air from respective cabin sections. Additionally, it is now possible to increase the size of the non-smoking section at the expense of the smoking section or vice versa simply by a respective valve control.

摘要:
An aircraft air-conditioning system (10) comprises an air-conditioning unit (12) that is connected by a main fresh-air line (16) to a mixer (18) in order to supply the mixer (18) with fresh air at a desired low temperature. A fresh-air branch line (20) that is connected upstream of the mixer (18) to the main fresh-air line (16) has a flow cross section that is smaller than a flow cross section of the main fresh-air line (16). In a region of connection of the main fresh-air line (16) to the fresh-air branch line (20) the main fresh-air line (16) and the fresh-air branch line (20) are so formed that a main fresh air flow flowing through the main fresh-air line (16) is deflected, while a fresh air branch flow flowing through the fresh-air branch line (20) experiences substantially no deflection,

An air dispersion system has a main supply line, a plurality of air outlets, which are connected via respective air exhaust routes to the main supply line, and at least one heating element, which is associated with at least one of the air outlets and can temper the air in the exhaust route of this air outlet.
摘要:
A system for air conditioning at least one partial region of an aircraft comprises 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, and that the air provided by the air providing device enters the aircraft region to be ventilated via the air inlet at such a temperature that a desired ambient temperature is set in the aircraft region to be ventilated.
