富氧空调的可行性探讨

Feasibility of oxygen enriched air conditioning

空调环境的氧含量普遍低于20.9%,有必要采取措施补充空调环境消耗的氧气,改善室内空气质量。简要介绍了几种制氧方法,提出将变压吸附制氧或膜分离制氧用于空调环境增氧的思路,并且描述了这两种增氧系统。以某体育场馆为例,对两种增氧系统与传统的增大新风量增氧方式进行了比较,认为前者在设备初投资和运行成本上都具有优势,而且能够满足空调环境的增氧要求。

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.
