數值演算技術應用於氣體滅火系統之流量計算

Application of a Numerical Computing Technique for the Flow Calculation of Gas Extinguishing Systems

本研究目的為經由數值演算技術評估鹵化烷及惰性氣體滅火系統。氣體滅火設備之藥劑計算依據美國國家防火協會 NFPA2001 規範，流量計算則引用 GB50370-2005 之計算方程式。研究流程為應用 GB50370-2005計算方程式經由AUTOCAD 二次開發技術演算，執行設計、繪圖、流量計算、工程數量統計等。研究結果顯示，應用 AUTOCAD 二次開發技術，進行數值演算，可快速有效地進行氣體滅火系統的設計與分析，產出系統材料、機房面積、排碳量等量化參數。這些參數可以做為設計者經由'理性決策'，來快速評估氣體滅火系統種類。

This study evaluated halogen and noble gas extinguishing systems using a numerical computing technique. The chemical dosage of the gas extinguishing system followed the 2001 standard set by the National Fire Protection Association, and the flow was calculated using the GB50370-2005 computing equation. Specifically, the GB50370-2005 equation was applied using the AutoCAD secondary development technique to execute the design, plot, and flow calculation, and compile engineering quantity statistics. The research results revealed that the AutoCAD secondary development technique can quickly and effectively design and analyze gas extinguishing systems. In particular, the effects of some quantitative parameters were identified, including the material of the system, room area, and carbon emission level. Furthermore, it was found that “rational decision-making” by a designer can efficiently evaluate the type of gas fire extinguishing systems according to these parameters.
