ABSTRACT:
An oxygen concentration system for producing oxygen from pressurized air comprises an electrochemical oxygen generator which selectively extracts oxygen from air by an electrochemical reaction. The oxygen concentration system includes first, second, and third concentric enclosures. The three enclosures produce three annuli formed between the enclosures. Air enters the top of the outermost enclosure, travels downwardly through the outermost annulus, crosses over the second annulus to the oxygen generators via ports, travels upwardly through the oxygen generators and back downwardly through the second annulus. By orienting the downward flow of the oxygen-depleted air next to the downward flow of the cooler incoming air, the incoming air is heated by the outgoing hot air, thereby increasing comfort to the user and reducing energy requirements.
