相对封闭环境增氧的实验研究

Experimental Study on Oxygen Enrichment in a Relatively Closed Environment

本文对相对封闭环境增氧进行了实验研究。结果表明,制氧机氧气流量对相对封闭环境内氧浓度变化起着决定性作用,循环风影响室内氧浓度的扩散和分布。相对封闭环境不增氧时,室内人员耗氧导致该环境内氧浓度明显下降,增氧可以显著提高相对封闭环境内的氧含量。与传统增新风空调系统相比,相对封闭环境增氧系统可以大幅度降低能耗,节约运行成本。

In this paper, the experimental study on oxygen enrichment in a relatively closed environment was carried out. The results indicated that the oxygen flow rate of the oxygen generation machine was the most important factor that would influence the oxygen concentration. In addition, the diffusion and distribution of oxygen concentration were also affected by the air circulating. Furthermore, when there was no oxygen fed into the environment, the indoor oxygen concentration decreased obviously because of the oxygen consumption by people. In other words, feeding oxygen could notably increase the oxygen content in a relatively closed environment. At last, when the oxygen enrichment system was compared with the traditional air-conditioning system with outdoor air, beth of the energy consumption and operating cost could be obviously reduced.
