應明確說明適用風場條件,如風速等級下對應安裝高度及間距。
3. 二度空間和三度空間油類火災實驗中,細水霧對於火場的抑制能力與油 類閃火點的溫度成正比,對於高閃火點的柴油火比低閃火點的汽油火易 於控制,水霧粒徑愈大者對油類火控制能力也愈小。
5.2 建議
在全球一致性注重於減碳及環保議題下,近年來各國分別簽訂京都議定書 和蒙特婁公約,常用的二氧化碳及鹵化烷系滅火系統,將因為溫室效應及臭氧 層保護,逐步停用或取代,許多替代品中細水霧系統,利用最天然潔淨的「水」
為滅火葯劑,真正對環境零污染和零傷害,且具有良好滅火效能,在國內僅止 於少數應用,尚未見到廣泛性的應用,顯見推廣不易,實在非常可惜,本研究 希望能抛磚引玉,見到更多產官學界的研究投入,提出以下建議:
1. 細水霧研究實驗如於室內進行,欲取代氣體滅火系統時,建議加做氣密 性實驗,可以讓空間氧氣含量變化數據更加準確。
2. 細水霧粒徑量測實驗,現行方式容易取因樣誤差造成結果誤差,水霧粒 子相互碰撞、干擾或結合因素未深入探討,可利用兩種以上粒徑量測方 法交互比對。
3. 相對撒水系統以單位面積放水密度做為不同火載量防護因應,細水霧可 以單位立方空間水霧通量做為火載量差異的防護因應,唯水霧通量單位 尚待統一。
4. 大空間火災實驗具有重要義意,可避免因尺寸效應,造成實驗數據失真,
相對成本雖高,長期性研究可有效降低架設成本。
5. 細水霧應用室外研究實驗,除本研究初次建構,尚未見相關研究計劃,
鑑於國內細水霧多為台電室外局部防護,值得投入更多研究。
