초고층 공동주택의 자연환기 적용 시뮬레이션

Abstract

This study is a simulation for natural ventilation application in a high - rise apartment building. 1) Ventilationefficiency increased with the increase of the area of the opening compared to the floor area in the ventilation efficiencyanalysis according to the opening area and the number of ventilation. That is, the ventilation number increased by0.033 times at every 50% increase of the opening area of 2%. The space with the tangent opening of the outside airmaintained the opening area compared to the floor area of 7%, and the space located at the side of the outside airmaintained the opening area compared to the floor area of 9-13% and maintained the ventilation frequency more than0.1 times. 2) In the comparison of the ventilation amount according to the shape of the window, the ventilation amountwas calculated in the order of double skin (DSF_PAF)> double skin (DSF)> single skin (SSF_Top). Therefore, inorder to maintain a wide opening area stably, we proposed the use of a dual envelope (DSF_PAF) with a windowwith the greatest ventilation in a box-type double envelope system, which has excellent control over individual spacesand is not affected by the height of the building.
