Abstract
ABSTRACT:The purpose of this study is to analyze and evaluate the 3 types of indoor ventilation methods such as natural, mechanical, and hybrid ventilation in high-rise building which is affected by stack effect and outdoor air pressure. For the evaluation of the ventilation capacity, CFD simulation was performed in a typical high-rise residential building. The results of the simulations are as follows：1) Natural ventilation method is not enough to the regulation. 2) In case of mechanical ventilation, congested area is occurred but meets the regulation. 3) In case of hybrid ventilation with stack effect, all the areas of indoor meet the regulation and congested area is reduced. 4) In case of high-rise building, the differences of ventilation rate among houses in the building are not large because the mechanical ventilation is main factor.Keywords:High-rise Building(초고층 건물), Stack effect(굴뚝효과), Natural ventilation system(자연환기장치), Airflow analysis(공기유동 분석) †Corresponding author Tel.: +82-51-510-2492; fax: +82-51-514-2230 E-mail address: ycahn@pusan.ac.kr
