Effect of ventilation on indoor particle and CO2 concentration in public transport buses

초록

The purpose of this study was to quantify the levels of indoor particles and CO2 according to ventilation methods of public transport buses. The measurements were conducted in twelve routes in 2 different lines, intercity and interstate. From the results, when ventilation system is operated indoor CO2 concentration is reduced while PM concentration is increased, especially for PM2. These results indicate that the ventilation system in public transport is not enough to control particulate matters. © 2018 15th Conference of the International Society of Indoor Air Quality and Climate, INDOOR AIR 2018.
