Feasibility of oxygen enriched air conditioning

The oxygen content in current air conditioned environment is usually below 20.9% and it is necessary to complement  oxygen to maintain  desirable indoor air quality. Briefly describes several oxygen generation methods and proposes a novel idea that integrates pressure swing adsorption(PSA) or membrane separation oxygen generation system with air conditioning system to keep the oxygen content level in air conditioned environment. Taking a gymnasium as an example, compares the two proposed oxygen complementing systems with the conventional one. The results show that the two proposed systems have some advantages in controlling the initial investment and operation costs and in meeting the requirements of air conditioned environment for oxygen.
