챔버를 이용한 객실 이산화탄소 흡착 연구

초록

People spend approximately 80 ~ 90 % of their time in various kinds of indoor spaces. And, in metropolitan area, most people spend more than 1 hour in public transportation everyday. For this reason, people's interest in the indoor air quality is drastically increasing. Among various indoor air pollutants, CO2 is one of the most severe environmental concerns. Ventilation is commonly used to keep low CO2 concentration in the passenger cabin. However, ventilation may worse the indoor air quality problem in case of subway because the tunnel is seriously polluted by particulate matters. In this study, an alternative way to remove CO2 was suggested. The adsorption of CO2 by CO2 adsorbent was studied. Zeolite modified with base was prepared, and CO2 removal performance was tested in 4m3 and 24m3 environmental chambers. It was found that CO2 adsorbent could effectively remove CO2 in the chambers.
