CONTAM을 이용한 고층건축물의 연돌효과에 따른 제연구역 차압특성 분석
Analysis of Differential Pressure Characteristics in Smoke Control Zones of a High-Rise Building under Stack Effect Using CONTAM
In this study, CONTAM simulation was used to analyze the floor-by-floor differential pressure characteristics of smoke control zones caused by the stack effect during winter in a high-rise building with six basement levels and 29 above-ground floors, with a total height of 105 m. Under indoor and outdoor temperature conditions of 20°C and −12.8°C, respectively, the neutral pressure level was formed at approximately the 12th floor, with negative pressure occurring on the lower floors and positive pressure on the upper floors. As the leakage area around elevator doors increased, the differential pressure on the upper floors tended to increase. The application of a pressure-relief flap damper significantly reduced overpressure in the vestibules of special evacuation stairways, whereas the pressure-reduction effect was limited in emergency elevator lobbies. Therefore, when designing smoke control systems for high-rise buildings, appropriate overpressure relief measures should be implemented by comprehensively considering the stack effect, door airtightness, vertical airflow, and the pressure characteristics of individual smoke control zones.

본 연구에서는 CONTAM 시뮬레이션을 이용하여 지하 6층, 지상 29층, 높이 105 m의 고층건축물을 대상으로 겨울철 연돌효과에 따른 제연구역의 층별 차압특성을 분석하였다. 실내온도 20℃, 외기온도 -12.8℃ 조건에서 약 12층 부근에 중성대가 형성되었으며, 하층부에서는 부압, 상층부에서는 양압이 나타났다. 엘리베이터 출입문의 틈새면적이 클수록 상층부 차압이 증가하는 경향을 보였고, 미압플랩댐퍼 적용 시 특별피난계단 부속실의 과압이 크게 감소하였다. 반면 비상용승강장에서는 저감효과가 제한적으로 나타났다. 따라서 고층건축물의 제연설비 설계 시 연돌효과, 출입문 기밀성, 수직 공기유동 및 제연구역별 압력특성을 종합적으로 고려한 과압해소방안의 적용이 필요하다.

Ever since next generation convergence technology became one of the most important industries in the nation, computing professionals have encountered a growing number of challenges. Along with scholars and colleagues in related fields, they have gathered in avariety of forums and meetings over the last few decades to share their knowledge, experiences and the outcome of their research. These exchanges have led to the founding of the International Next-generation Convergence technology (INCA) on December 1, 2015. INCA was registered as an incorporated association under the Ministry of Information and Communications. The main purpose of the organization is to improve our society by achieving the highest capability possible in next generation convergence technology.
