Embodiment Construction

[0019] figure 1 An aircraft 2 according to the prior art is shown which comprises eight different regions 4 which can be air-conditioned in different ways. The air is conducted into the individual zones 4 via zone air lines 6 , which are supplied with air via mixing chambers or mixing units 8 . In the mixing unit 8 , the correspondingly conditioned fresh air is mixed with the used cabin air from the separate zone 4 and used for further air conditioning of the zone 4 . In order for the individual zones 4 to be individually air-conditioned, the air supplied via the mixing unit 8 must be set in such a way that it has the minimum temperature required for the different zones 4 . This minimum temperature can be, for example, 18°C. To increase this air temperature, relatively warmer bleed air 10 is used, which is distributed in each case via conditioned air valves 16 to a plurality of conditioned air lines by means of one or more conditioned air distributors 12 14. The conditione...

Abstract

The invention relates to an air conditioning system for a transportation means, having a plurality of zones (20) to be air-conditioned, wherein the plurality of zones may be variably air-conditioned by means of processed supply air in combination with individual trim air conduits (24), and wherein the air conditioning system further has at least one heat exchanger (32) for heating supply air by means of the exhaust heat of a fuel cell (36), and for discharging the supply air into a trim air distributor (28) supplying the trim air conduits (24).

Description

[0001] References to related applications [0002] This application claims priority to U.S. Provisional Application No. 61 / 190,082, filed August 26, 2008, and German Patent Application No. 10 2008 039 782.2, filed August 26, 2008, the disclosures of which are incorporated by reference This article. technical field [0003] The invention relates to an environmental control system for a vehicle, a method for differential air conditioning of an in-cabin area of ​​a vehicle, the use of an environmental control system in a vehicle, and an aircraft comprising at least one such environmental control system. Background technique [0004] For individual temperature control, the cabin of a vehicle is usually divided into zones, wherein each zone preferably comprises its own air supply line delivering air with individually predetermined parameters, such as temperature, to the in the corresponding area. For example, modern commercial aircraft often include environmental control system...
