Embodiment Construction

[0063] Identical or similar components in different figures are provided with the same reference signs. The illustrations in the drawings are schematic and not drawn to scale.

[0064] figure 1 A known device for supplying passengers with fresh air and for cooling and / or heating the aircraft cabin 18 is shown. Cool fresh air is distributed in the aircraft cabin 18 by means of the mixing chamber 16 . Cooled fresh air from the air-conditioning system 17 is supplied to the mixing chamber 16 via corresponding ducts 3 . In the event of a pipe rupture which would result in depressurization of the nacelle, a non-return valve 15 is provided in the pipe 3 . Cold air below the 0°C boundary is blown into the duct 3 so that parts such as the non-return valve 15 will be at risk of freezing.

[0065] figure 2 and image 3 An embodiment according to the basic principles of the invention is shown. figure 2 An air conditioning system is shown with two air outlets on duct 1 and duct 2 ...

Abstract

The present invention relates to an arrangement for deicing pipeline connections of an aircraft, which are connected to all fresh air outlets of an air conditioner, whose construction comprises the functions of multiple turbines and heat exchangers, having a first pipeline (1), which is connected to a first turbine (TA), and a second pipeline (2), which is connected to a second turbine (TB), the two pipelines (1, 2), which are each connected downstream from the two turbines (TA, TB) and to which process air is fed at the turbine outlets, being connected at the pipe ends and being continued using a third pipeline (3). The arrangement is characterized in that a first hot air source (11) is fed hot fresh air from a bleed air system of the aircraft and is connected at its outlet to a fourth pipeline (4), into which temperature-reduced fresh air is fed from the hot air source (11). The fourth pipeline (4) is connected at its pipe end to two further valve-regulated pipelines (5,6), of whicha fifth or a sixth pipeline (5, 6) is connected to the first or the second pipeline (1, 2), and through which temperature-reduced fresh air is transported and fed valve-regulated to the first and/or second pipeline (1, 2).

Description

[0001] References to related applications [0002] This application claims priority to German Patent Application No. 10 2006 048622.6, filed October 13, 2006, and U.S. Provisional Patent Application No. 60 / 829,348, filed October 13, 2006, the disclosures of which are incorporated by reference This article. technical field [0003] The invention relates to a device for a duct connection of an aircraft and a method for regulating the temperature of process air for a duct connection of an aircraft. Background technique [0004] In current passenger aircraft, the cabin is air-conditioned using cold ambient air on the one hand and hot exhaust air from a so-called bleed air system of the aircraft engine on the other hand. Ambient air is supplied into the aircraft cabin for fresh air supply of passengers and for temperature control of the aircraft cabin. Cool fresh air is mixed with hot bleed air in a mixing chamber - thereby controlling the temperature - and distributed into the...
