Adsorptive Control of Indoor CO2 in Car using a CO2 Adsorption System for Car

초록

high concentration of co2 in car is dangerous because driver may feel sleepiness or headache. ventilation is the easiest way to reduce CO2 concentration. but there are some cases when the ventilation is not available. For exeample, when the car is running in downtown area, ventilation should be minized because the ambient air is apt to be seriously polluted with various kinds of air pollutants. in this study, CO2 adsorption system was prepared and installed in a car to reduce CO2 concentration without ventilation. when the car speed was lower, CO2 concentration increased more rapidly. but, when the car speed was higher, CO2 concentration increased a little bit slowly. it means the car was faster. CO2 concentration reached around 4,000 ppm in downtown area, but it reached around 3000 ppm when the car runs on highway with four passenger onboard. when the prepared Co2 adsorption system was turned on, CO2 cencentration could kept at lower CO2 concentraton than when it was not turned on. CO2 concentration could be kept at lower than 3000 ppm in downtown area, and at lower than 2000 ppm in highway in the same condition. develoment of more efficient CO2 adsorption, and more efficient design for redusing CO2 in shorter time should be studied for the practical application of this system.
