|
The elevator is needed healthy and comfortable indoor air quality (IAQ) for using many people, but we found nothing
about IAQ studies of an elevator. In general, air in the elevator car is sucked from the elevator’s hoistway straight into the car using a fan. The air sucked into the hoistway may be filled with dust, mold and bacteria.
This study was performed to measure of characteristics of indoor air quality (PM10, falling bacteria, CO2, Rn and HCHO)
in elevator`s hoistway, CAR and lobby of 8 sites (4 apartments and 4 commercial buildings) in Gyeongnam from May, 2010
to January, 2011. With regards to the differences of pollutant distribution among hoistway, CAR, and lobby, the
concentration of Rn and HCHO were the highest in hoistway followed by CAR and lobby, and PM10, falling bacteria and
CO2 were the highest in CAR followed by hoistway and lobby. Mean concentrations of PM10 were 104.9 μg/m3 in CAR,
92.3 μg/m3 in hoistway and 68.2 μg/m3
in lobby, respectively.
