Abstract

High concentration of carbon dioxide at subway cabin is one of the serious environmental concerns because carbon dioxide causes drowsiness, headache, and nervelessness of passengers. Ministry of Environment set a guideline for indoor carbon dioxide levels in train or subway in 2007. In this study, a carbon dioxide removal system for subway cabin was developed and tested using a test subway cabin. Various types of modified zeolites were used as the adsorbent of carbon dioxide. The tested zeolites were applied to the subway cabin, and showed high potential to lower the indoor $CO_2$ level.

지하철 객실은 고농도의 이산화탄소로 오염되기 쉬운데, 이로 인하여 지하철 승객의 졸림, 두통, 무력감 등을 야기하기 쉽다. 이 때문에 환경부에서는 2007년에서는 열차와 지하철 객실의 이산화탄소 농도에 대한 가이드라인을 정한 바 있다. 본 연구에서는 지하철 객차용 이산화탄소 저감 시스템을 개발하고 실험용 객차를 이용하여 성능시험을 수행하였다. 다양한 종류의 개질 제올라이트를 이산화탄소 흡착제로 사용하여 지하철 객실 내부의 이산화탄소 농도를 저감할 수 있었다.
