초록

An aircraft cabin air treatment system configured in accordance with the invention utilizes oxygen enriched air, which is produced as a byproduct of an onboard inert gas generation system. The oxygen enriched air is released into an environment under ambient pressure conditions, i.e., at a relatively low absolute pressure compared to the cabin pressure. The low pressure oxygen enriched air is compressed with a cabin air compressor, and the outside air is routed back into the cabin. The cabin air compressor functions to generate oxygen enriched outside a...

청구항

What is claimed is: 1. A method for processing cabin air of an aircraft having a cabin, said method comprising: obtaining used cabin air at a relatively high absolute pressure at an input of an onboard inert gas generation system ("OBIGGS") generating, with said OBIGGS, oxygen enriched air; providing, at a relatively low absolute pressure, said oxygen enriched air to an intake of a cabin air compressor; and generating, with said cabin air compressor, outside air at a relatively high absolute pressure, said outside air including said oxygen enriched air....
