A modified gas components system for CA-storage using a gas separation membrane was designed, constructed and tested. The membrane has permeability of carbon dioxide, oxygen and nitrogen in order. The distinctive feature of this system is that the operations of carbon dioxide reduction, oxygen introduction and nitrogen introduction to the storage room can be done by selecting circuit with an only membrane module. And by using these three operations the gas components in the storage room can be controlled. It was effective to decrease carbon dioxide content and increase oxygen content. But the operation of nitrogen introduction to the storage room didn't work well. Then to verify whether it can operate both oxygen introduction and nitrogen introduction with an only membrane module, gas permeation versus gas flow was simulated by using computer. It became clear that their two operations could work well by controlling gas flow to membrane module. Therefore this system was improved and the method of controlling gas components in the storage room was shown.

设计、构建了一种改良的气体分离膜储气系统，并进行了试验。膜依次对二氧化碳、氧气和氮气具有渗透性。该系统的独特之处在于，只需选择一个膜模块的电路，就可以完成对储存库进行二氧化碳还原、氧气导入和氮气导入的操作。通过使用这三种操作，可以控制储气室中的气体成分。对降低二氧化碳含量、提高氧含量有较好的效果。但储物间氮气导入操作效果不佳。然后，为了验证膜模块是否可以同时进行氧导入和氮导入，利用计算机模拟了气体渗透与气体流量的关系。很明显，通过控制气体流向膜模块，这两种操作都可以很好地工作。为此，对该系统进行了改进，并提出了控制储气室气体组分的方法。
