초록

A system for oxygen enrichment of fresh air is used as a module in the environmental control system of aircraft cabins. Due to the increased oxygen partial pressure, the total air pressure in the aircraft cabin may be reduced, thus leading to increased cost economies in design and/or operation. The module provides oxygen-enriched fresh and recirculated air that is free of any particulate and gaseous pollutants, especially ozone and carbon dioxide.

청구항

[ What is claimed is:] [1.] A system for supplying air to pressurized aircraft cabins, comprising:a filter arrangement that filters fresh air from outside an aircraft cabin and cleans said fresh air of gaseous pollutants;a membrane module including a membrane comprising hollow fibers for oxygen enrichment of filtered and cleaned fresh air;a conducting arrangement that conducts filtered and cleaned fresh air into said cabin from said membrane module; anda unit for cleaning and recirculating used cabin air into said cabin.
