The Influence on the Stack Effect with the Opening of Smoke Ventilators in High-rise Buildings

초고층 건축물에서 배연창 개방이 연돌효과에 미치는 영향

The effects on the performance of natural smoke exhaust ventilators installed in high-rise buildings were analyzed depending on the wind velocities and smoke temperatures using CONTAMW tool. The results showed that the smoke exhaust ventilators can maintain given performances in such conditions as low smoke temperatures and low wind velocities. However, high smoke temperatures and high wind velocities can prevent the smoke ventilators to exhaust smokes from the fire room. Significant changes in stack effects in high-rise buildings can also occur with the opening of smoke ventilators in the fire floor.
