Air supply system for aircraft e.g. passenger aircraft, has coupling device which fluidically connects cooling-air system and ventilation system, such that air flow in cooling-air system drives ventilation system

摘要

The system (100) includes a fresh-air system (110) which leads fresh air into the aircraft cabin and coupled to a circulating air system (140), such that used cabin air is led into the fresh-air system. The fresh-air system includes an air conditioner (130) cooled by a cooling-air system (150) coupled to a ventilation system (170). The ventilation system ventilates the installation space (190) of the air conditioner. A coupling device (160) fluidically connects the cooling-air system and the ventilation system, such that air flow in the cooling-air system drives the ventilation system. An independent claim is also included for an air-streams mixing method.
