초록

실내공기질의 중요성이 날로 부각되고 있다. 특히 휘발성유기화합물(VOCs)에 의한 실내공기의 오염은 매우 심각한 환경문제가 되고 있다. 이에 본 연구에서는 철도차량 객실용 시트커버와 바닥재를 대상으로 청정한 챔버 안에 넣고, 고정 환기 조건에서 VOCs 방출특성을 조사하였다. 챔버는 온도 $25{\pm}1^{\circ}C$, 상대습도 $50{\pm}5%$를 유지하면서 방출량을 조사하였다. 실험결과 바닥재가 시트커버보다 많이 양의 VOCs를 방출하는 것으로 나타났는데, 이는 바닥재가 PVC 재질이기 때문인 것으로 보인다. 방출량은 시간에 따라 점차 감소하였다.내장재에서 방출되는 VOCs는 객실 승객의 건강을 위협할 수 있으므로, VOCs를 덜 방출하는 내장재가 사용되어야 한다.
