Study on the adsorptive removal of carbon dioxide in testing chamber

초록

Carbon dioxide (CO2) is the indicator of ventilation rate for indoor space, and the high CO2 concentration means the indoor air quality of the space is not good. However, when outdoor air quality is bad, the ventilation may worse the indoor air quality. Furthermore, concern of CO2 itself is increasing, because high concentration of CO2 may cause dizziness, drowsiness, or headaches. Nowadays, control of indoor CO2 using various adsorbents is tried. Silica, alumina, activated carbon, and zeolite are widely applied for the adsorption of indoor CO2. In this study, an active CO2 removal method using zeolite adsorbents was studied.
