中文摘要 | 通風排煙是區劃空間火災中非常重要的消防戰術,本研究利用美國國家標準與技術研究院(National Institute of Standards and Technology, NIST)研發的FDS軟體,在同樣的區劃空間中模擬四種通風排煙消防戰術。本研究採用一配置簡單並附有一門窗的居室為區劃空間,藉由FDS軟體模擬後,研究發現不論是區劃空間內部靠近天花板溫度或煙層中能見度,當消防人員採取送風機正壓排煙消防戰術時,能夠在最短的時間內將溫度及濃煙排出區劃空間,其次為排煙機負壓排煙,再其次為水霧射水水力排煙,以自然排煙最慢。本研究結果能提供消防人員評估適宜的通風排煙消防戰術,以提升救災的戰略戰術考量。 |
英文摘要 | Fire ventilation is a very important firefighting technique for compartment fires. This study simulated 4 types of fire ventilation using the Fire Dynamics Simulator, a computerized simulation program developed by the National Institute of Standard and Technology (NIST) of the U.S.A. in the same compartment. The compartment involved in this study is a normal room with window and door. From the computerized simulation, performed by the Fire Dynamics Simulator, temperature near the ceiling and smoke in the compartment were exhausted in the shortest amount time using of a positive-pressure ventilation with a PPV fan. The second shortest time was a negative-pressure ventilation using an exhauster. The fog nozzle spray ventilation was found to be the third fastest where natural ventilation was found to be the slowest of these four types of fire ventilation. This conclusion can help firefighters evaluate the benefits of fire ventilation for better firefighting strategies and tactics. |
