台灣地區人口稠密,依內政部的統計,1997至2006年台灣地區的人口密度為618.7 人/平方公里,在較高的人口密度下,公共場所上的安全問題也就相對重要,據消防署統計,1997年至2006年間,建築物的火災發生類別中,公共場所的火災發生率,平均約占10%,雖然只有10%,但公共場所的火災卻是我們最容易疏忽及不易掌握的,往往一旦發生火災,常常造成重大人員傷亡及財物損失。 本研究以民國84年台中市衛爾康西餐廳為研究對象,使用「FDS」軟體來分場,透過場模式來模擬火場中之物理現象,探討火場中之熱傳遞現象、煙流、上層溫度、CO濃度的變化,並針對火場之主要影響因素,改變各種不同參數,分析火場在各種不同情況下例如:主火源位置、大小、灑水器的裝設、開口大小及位置對火場變化之影響,並期研究成果能對相關公共場所的防火工程上有所參考價值。
Taiwan is populous in recent years, according to the statistics data of the Ministry Of Interior. Between 1997 and 2006, the population density of Taiwan is 618.7 persons per square kilometer. The security problems in public places are relatively important too. In accordance with the data of Fire Agency, from 1997 to 2006, there are 10% of building fire occurred in public places. Although there is merely 10%, yet the fires in public places are easy to be neglected and difficult to be controlled. If once there is a fire, it will often lead to great casualties and property losses. This thesis utilizes Fire Dynamic Simulator (FDS) field model to simulate the residential fire accident occurred in Wei Er Kang restaurant , and research heat transmission phenomenon、smoke flows、upper layer temperatures and change of CO concentrations. To aim at main influence factor of a fire scene, change all kinds of parameters, and analysis fire field under different conditions, such as main fire source position, fire sizes, sprinkler to be set up and size of opening and position, that effect to a fire scene. The results expect to be a reference for the design of fire fighting engineering.
