Abstract
Since the environment control unit for an airplane has such an arrangement that air is drawn out of a cabin 2, oxygen and water molecules alone are separated from the drawn air by a selective permeable membrane 21, the permeated oxygen and water is supplied to the cabin 2 again and the remaining nitrogen is supplied to a fuel tank 41 in order to prevent explosion, it is possible to reduce an amount of air extracted from an engine 1 by far that is required to facilitate respiration for passengers and to prevent explosion.
Claims6
An environment control unit for an airplane wherein air of high-temperature and high-pressure is extracted from an engine or an auxiliary power portion of an airplane, the extracted air is regulated in temperature and pressure by an air conditioning portion and then the regulated air is supplied to a pressurized chamber, characterized by that air exhausted from the pressurized chamber or air drawn out of the pressurized chamber is separated into air enriched with nitrogen and air enriched with oxygen, the air enriched with oxygen is supplied to the pressurized chamber again and the air enriched with nitrogen is supplied to an inflammable portion such as a fuel tank.
