VENTILATION SYSTEM FOR AIR-CONDITIONING LONG-RANGE PASSENGER AIRPLANE - Daimler Benz Aerospace Airbus Gezel Shaft Mitt Beschlenktel Haftung

Title:

VENTILATION SYSTEM FOR AIR-CONDITIONING LONG-RANGE PASSENGER AIRPLANE

Document Type and Number:

Japanese Patent JP3088982

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To prevent air replacement done through the blow-by or the starting point of a stairway by compensating for a pressurization state between passenger decks in a ventilation system for air-conditioning long-range passenger airplane in which a plurality of passenger decks are connected through the blow-by or the starting point of a stairway.
SOLUTION: An upper deck region 2 is connected to a principal deck region 3 through at least one duct-like pressurization chamber connecting path. The upper deck region 2 is coupled to at least one fun unit 72 connected to a second functional interface part 10 on the outlet side. Drafting part of the supply air supplied to the upper deck region 2 by the fun unit 72 exactly materializes volume flow compensation balance between supply air volume and exhaust air volume with respect to the entire upper deck region 2. The upper deck region 2 is partially separated from the principal deck region 3, being connected to interface parts 9, 10 provided to the upper deck region 2 and the principal deck region 3, respectively.
