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.

With a method for controlling the temperature of feed air which is injected into the cabin zone of a passenger aircraft, the cabin of which is sub-divided into several cabin zones supplied respectively with specially temperature-controlled feed air, the temperature of the injected feed air is controlled for each cabin zone, dependent upon the deviation of an injection temperature actual value for the feed air injected into the cabin zone in question, measured by sensors, in relation to an injection temperature optimum value. If there is no, or at least no usable reading of the ambient temperature of this cabin zone for a cabin zone, an optimum value for the injection temperature of this cabin zone can be established in accordance with a variation, whereby it is determined upon the basis of the injection temperature optimum values and/or the injection temperature actual values of other cabin zones, whereby the measurement by sensors of the cabin temperature works reliably. In accordance with another variation, the injection temperature optimum value of a cabin zone can be established without measuring ambient temperature by sensors or without reliably measuring ambient temperature from the temperature measured for the external surrounds of the aircraft.

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.

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 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.

A method and apparatus is provided for air conditioning two passenger decks in an aircraft, especially a high capacity aircraft. The engine tap air stream is provided for air conditioning the upper deck passenger cabin and the lower deck passenger cabin. The air stream is cooled in at least one air conditioning plant, mixed with recirculated air from the lower cabin in at least one premix chamber, and then mixed with recirculated air from the upper cabin in local mixing chambers. The finished air streams are directed to the upper deck and the lower deck passenger cabins. The upper deck exhaust air is essentially completely used as recirculation air being mixed with the conditioning air in the local mixing chambers. The lower deck exhaust air is partially used as recirculation air being mixed with the conditioning air in the premix chambers, and is partially exhausted overboard. The desired air temperature, quality, and quantity can thus be achieved independently in the two passenger cabins, in an energy efficient and space-saving manner.
