생활수준이 향상됨에 따라 에어컨은 이제 생활 필수품이 되었다. 단순히 온도를 조절하는 데서 나아가 최근에는 기류제어 공기청정 탈취 살균 제균 등 다양한 부가기능을 갖추고 있다. 이렇게 편리한 에어컨을 안전하게 사용하려면 적절한 설치 및 사용관리 방법을 잘 알아야 한다.

After installation of platform screen door (PSD) in subway stations, particulate matters (PMs), which are originally ventilated through the platform, are accumulated inside the tunnel of the subway system. It deteriorates an air quality inside the tunnel. To ventilate the accumulated PMs inside the tunnel, the natural ventilator which are located inside the tunnel (namely, tunnel ventilation system) are used as only one circulation system. In addition, the installation of PSD can affect to the aerodynamic variations inside the tunnel, since the PSD system was not considered factor when the tunnel ventilation system was designed. However, the researches about the tunnel ventilation system have not been adequate. Therefore, this study is carried out with two objectives: 1) to measure the velocity of air current by the train-induced wind, when the train passes through the tunnel, and 2) to investigate the typical patterns of air current by quantitatively evaluating the characteristics of inflow/outflow of air current which passes through the natural ventilation system. This study can suggest the basic standard to newly design the tunnel of the subway system as well as the ventilation system.
