CFD 시뮬레이션을 통한 엘리베이터 샤프트 냉각 시스템의 성능 검토

The stack-effect in high-rise buildings in winter causes many problems such as difficulties in opening or closing doors, infiltration, energy loss, noise and fire protection. Stack effect is influenced by temperature difference between the interior and exterior of building and the height of building. As an attenuation method for stack effect, the architectural methods are generally used. However, as though architectural methods were fully adopted, the problems are reported as ever in tall building. In this study, a new method to reduce stack effect will be suggested. As an active control method against the stack effect, E/L shaft natural cooling method is suggested. In this paper, the concept of E/L shaft natural cooling system and its reduction performance of stack effect by CFD simulation will be reported.
