CREATING BREATHING ATMOSPHERE Russian patent published in 2011 - IPC F24F3/14 F24F3/16 

FIELD: process engineering.

SUBSTANCE: proposed method comprises forming external gas flow from ambient atmospheric air, compressing said external gas flow, separating it component-by-component in primary membrane module by forcing it along surface of selective membrane in high-pressure zone, extracting gas flow not penetrating said membrane from aforesaid high-pressure zone, forming feeding gas flow from that extracted from low-pressure zone of primary membrane module, and feed it into operating chamber. Prior to feeding compressed external gas flow into primary membrane module, it is separated component-by-component in additional membrane module and fed into high-pressure zone of primary membrane module. Prior to feeding it into said additional module, it is dried to form water condensate. Portion of said condensate is evaporated. Gas flow is extracted from low-pressure zone of additional membrane module and divided into three portions.

EFFECT: controlled concentrations of oxygen, carbon dioxide and humidity.
