桃園國際機場第一航廈,於民國六十八年啟用至今,已無法負荷該龐大運輸需求,故於2004年由行政院推動之「挑戰2008:國家發展重點計畫」計畫進行改建,利用曲線帷幕將航廈兩側3F外部平台包覆,形成一室內曲線挑空之大型空間,以此改善空間利用性。 由於該挑空空間使用用途特殊,必須採用性能式設計,但在煙害影響上卻出現煙流擴散之可能情形,本文之研究目的主要分為兩種:(一)討論大型挑空空間內發生火災時,不同火源規模與位置所產生之煙流行為,對於該空間內各樓層之危險程度。(二)討論煙流經自然排煙方式排出時,風向對於火災煙流的牽引效果;進而了解其會否對於該空間排煙效果造成影響。 本研究以桃園國際機場擴建之大型挑空空間為模擬對象,模擬其火災煙流情形,研究成果如下: 一. 大型空間當起火樓層越低,若挑空處無設置樓層區劃,則越高越遠之空間位置,其越快受到煙流影響。 二. 較大風速對於自然排煙效率可能產生抑制之影響。 三. 進氣口於受風狀態下造成空間內煙流行為改變,影響蓄煙效果。
Taoyuan International Airport, the first terminal, in the Republic of China since the opening of 68 has been unable to load the huge demand for transportation. Therefore, the Executive Yuan in 2004 to promote the "Challenge 2008 Six-Year National Development Plan" plans to carry out the conversion.In order to improve spaces, we use curve curtain to enclose the flatform in 3F of terminal to form a curvature enormous space. Because the function of space that was evacuated is particular , we must desing it functionally.But it might cause smoke spread anywhere. The main purpose of this study is divided into two: (i) discussing the degree of risk on each floor in the building ,when the fire taking place and generated the smoky flow in different scale and location of atrium. (ii) disscussing effection of smoky flow attraction by the wind direction when smoky flow discharged naturally. Furthermore we want to realize whether it will effect the smoky flow. In this study, the expansion of the Taoyuan International Airport, pick a large Atrium for the simulated object.Simulation of the fire plume cases, research results are as follows: 1. Large space when the fire broke out the lower floors, if not set up out the floor space Department divisions, the higher the farther the location of the space, the faster the flow affected by the smoke. 2. Greater efficiency of natural draft for the wind speed may have the effect of inhibiting. 3. Intake in the state caused by the wind breathing space to change the pandemic, the impact has the effect of smoke.
