摘要

在台灣社會上，不論是偏遠地區或是都市舊社區中，隨處可見，附設卡拉ok的小吃店或是小型但內部裝潢遊走或無視法規規定的KTV；這些場所都隱藏著危險。
本文以FDS探討實際案例中空調風管對火場之影響，但因年代久遠，除了內部建材及尺寸外，其中火場內的空調風管尺寸卻不可得，故此本文初期以空調負荷書來先行評估早期營業場所之空調負荷，並選用合適的矩型風管尺寸。然而FDS並不適合用來做為室內空調之模擬，因此本文在空調模擬之部份，則選用PHOENICS軟體，進而由模擬截面圖，來確認選用之風管尺寸，是否合於本文實際案例「神話世界KTV」。
在本文中，FDS是分析其空調風管對火場的影響，在PHOENICS軟體確認風管無誤的情況下，我們則以同尺寸的風管來建構FDS之模型，並探討外部開口、內部開口、易燃物等因素對火場的影響。在最後則探討灑水器、建材變化是否能替人員爭取時間，以減少悲劇的發生。

In Taiwan society, any remote districts or old community in cities, we can see greasy spoon with small karaoke everywhere, or the karaoke restaurant decorated beautifully but disregard the fire safety statutes and dangers concealed behind.
Fire Dynamics Simulator (FDS) has been proposed to investigate the influence of air conditioning pipeline on fire building by actual case discussed in this article. Because the building is obsolete in ages, the size of air conditioning pipeline which lay in fire building cannot be obtained, besides the indoor building materials and size. This article will use a list of air conditioning load to evaluate place that has air conditioning load beforehand, and choose the applicable size of rectangular pipeline in initial period. However, FDS is improper for simulating the indoor air conditioning pipeline. Therefore, PHOENICS software has been used for air conditioning pipeline simulation in this article, in order to confirm that the size of pipeline can be used to actual case – “Legend world KTV”, from cross-section illustration of simulation result.
In this article, FDS has been used to analyze the effect of air conditioning pipeline on fire site. After the size of pipeline confirmed by PHOENICS, a same size of pipeline model is built for FDS to discuss factors such as outside opening, inside opening, tinder that has the effect on fire. In final, a discussion about sprinkler system and change of materials if it could get escape time for people, then decrease tragedy to occur.
