본논문에서는 실내의 바닥마감재로 널리 사용되고 있는 온돌용 마루와 실내에 설치한 대형 가구(붙박이 장)를 중심으로 시간 경과에 따른 VOCs 농도를 측정하고, 휘발성유기화합물 중 BTEX(Benzene, Toluene, Ethylbenzene, m, p, o-Xylene)를 중심으로 연구를 진행하였다. 또한 시간경과에 따른 실측치를 바탕으로 이를 예측할 수 있는 예측식을 개발하고 이를 이용하여 환기회수 변화에 따른 실내의 휘발성유기화합물 농도 감소를 예측하였다. |
| 요약2 |
In this study, time-dependent concentration variations of VOCs from fixed furniture and Ondol floor widely used as finishing material of the floor were measured, and prediction equations were developed based on the measured results.
VOCs were measured and analyzed based on EPA TO-17 and NIOSH 1500, 1501 method respectively, and GC/FID were used for the analysis of VOCs concentration. Measurements were carried out for 10 days after the installation of furniture and for 40 days after the installation of the floor in the residence constructed more than 10 years ago.
In both case of floor and furniture installation, time-dependent concentration decay of VOCs can be properly converted into logarithmic scale. Especially in case of furniture, toluene showed the highest concentration and took longest time to decay.
As a result of the prediction of VOCs concentration decay under different air change rate using estimated equations, concentration decay rate of indoor VOCs increased rapidly as the air change rate also increased. |
