Problems solved by technology

[0008] A major disadvantage of this technology as described above is that the energy required for pressurization and air conditioning in the form of aerodynamic energy is provided by the jet engine compressor, but this split of aerodynamic energy cannot be effectively controlled in terms of thermodynamics
A large proportion of the shunt energy is dissipated through heat transfer and throttling and therefore cannot be further utilized
Another disadvantage is that the shunting conditions are mainly dependent on the load conditions of the power unit, which is mainly determined by the thrust
Additionally, diverted airflow from the core flow of the powertrain has a negative impact on powertrain performance

Embodiment Construction

[0019] figure 1 A schematic diagram of an air system 1 according to a preferred embodiment of the present invention is shown. The air system 1 includes an electric motor 2 for driving a compressor 3 . Compressor 3 compresses air from the external environment to cabin pressure plus additional pressure losses due to cross flow and distribution. The required airflow is derived from the maximum demand depending on the cabin layout. For example, if greater cooling capacity and / or heating capacity is required, the motor 2 can provide greater power and increase air pressure and / or air temperature.

[0020] figure 1 The air system 1 in also includes a turbine 4 through which compressed air can be supplied to a condenser 5 . The function of Turbo 4 will be referred to later image 3 Make an introduction.

[0021] The air system 1 also includes a flow controller 6 to control the compressed air flow delivered by the compressor 3 to a desired value, which mainly depends on the cabin...

Abstract

An air system for pressurizing and air-conditioning aircraft cockpit and passenger cabin spaces, comprising a compressor (3) for compressing an air flow, wherein the air flow to be compressed is passed through a ram intake (13, 14) Extracted from the environment outside the aircraft and supplied through heat exchangers (15, 18) to at least one zone (10A-D) to be pressurized and air-conditioned.

Description

[0001] This application claims priority to US Provisional Patent Application No. 60 / 647108, filed January 26, 2005, and German Patent Application No. 102005003645.7, filed January 26, 2005, the entire contents of which are incorporated herein by reference. technical field [0002] The present invention relates to an air system, in particular to a non-bleed air system with integrated zone temperature controllers for pressurizing and air conditioning aircraft cockpits and cabins. Background technique [0003] Known air systems and / or air conditioning systems for use on aircraft with jet engines and pressurized passenger cabins utilize aerodynamic energy in the form of compressed airflow from the jet engine compressors, which drives the air conditioning system while being conditioned by the air conditioning system and used as fresh air is supplied to the cabin. [0004] To operate a conventional air conditioning system, the jet engine compressor continuously draws the jet engin...
