摘要(中) 許多公共建築物,如旅館、宿舍、醫院病房和辦公室等,通常都具有長通道型的內部走廊。這類建築設計即使房間有向外的窗戶開口,仍類似單側開口的房間,容易造成房間與走廊之間的換氣通風效果不佳,房間內很容易產生悶熱,形成不舒適的居室環境。而國內外研究建築通風之文獻,甚少針對走廊通風換氣進行深入的研究。有鑑於此,本研究藉由風洞實驗來探討室內空間與走廊之間的風壓通風。實驗結果顯示若走廊通風差,會導致房間與走廊之間的換氣率不佳。研究也探討室內裝設屏風對貫流通風的影響,結果發現屏風所產生的阻力因子會隨屏風面積(阻滯比)增加而變大,設有室內屏風的換氣率可用Chu and Wang (2010)的阻力模式加以預測。最後,實驗尚使用示踪氣體方法量測單側開口和雙側開口狀況下,不同的風速、風向及開口大小的換氣率。實驗所得之無因次換氣率與Warren (1977) 和 Kato et al. (2006) 之實驗結果相近。
摘要(英) Many buildings, such as hotel, dormitory, hospital rooms and office space have a long internal corridor (hall way). This kind of building design yields poor ventilation between corridor and rooms, even the room has an open window on the opposite wall. This study used wind tunnel experiments to investigate wind-driven ventilation between corridor and room. The results indicated that the ventilation rate will be reduced if the corridor is blocked. This study also explored the internal resistance of a plate inside the building and found that the resistance factor increased as the blockage ratio of the plate increased. The ventilation rate with the internal plate can be predicted by a resistance model of Chu and Wang (2010). Finally, the exchange rates of single-sided and two-sided openings under various wind speeds and directions were measured by using the tracer gas technique. The dimensionless exchange rates agreed with the results of Warren (1977) and Kato et al. (2006).
