초고층 주상복합아파트의 기밀 성능 및 연돌 효과 특성에 관한 연구

The purpose of this study is to assess the air tightness and to analyze the behavior of the stack effect in high-rise apartments. In this study, the air tightness and air pressure of two different apartments were measured in both summer and winter. Moreover, the measured and theoretically calculated air leakage rate were compared to each other. As a result, the following conclusions were obtained. According to ASHRAE Standard 119-1988, both apartments can be considered to be relatively airtight. The indoor-outdoor pressure difference measured in winter at both apartments were higher than those measured in summer due to the relatively higher temperature difference between the indoor and outdoor air in winter, causing stack effect. Furthermore, there were some error between the measured and calculated air leakage rate in both apartments, but the variation pattern of air leakage were found to be similar to each other.
