도시철도역사 승강장 환기시스템에 가변운전방식 도입 가능성 검토에 관한 연구

Abstract

This research examined possibility of introducing variable speed operation for ventilation systems in subway stations' platform by experiments. As a result, appropriate amount of air flow has also gained at terminal diffuser when variable speed operation method has applied to existing air ventilation system. Concentration of fine dust was similar with on/off method, and both control method have fulfilled legal standards while variable speed operation method showed better amount of supplied air volume and reduction of energy cost.
