根據研究結果,證明了熱量由火源處垂直上竄,再由水平擴散,滿足室內熱對流效應。散熱設備-風扇有利於降低室內溫度,延長逃生的時間,FDS(Fire Dynamics Simulator)與ANSYS比較,更能得到真實火場的溫度分佈,而ANSYS能分析構件內部溫度,所以兩者間在分析上具有良好的互補性。

During to rapid economic development, human development is
increasingly serious, Taiwan is facing a shortage of
resources and environmental pullation problems, because recyclability of steel and less environmental pollution, comply with the requirements of sustainable development of nature, steel gradually replaced by concrete buildings.
But poor fire resistance is a fatal drawback for steel, the main purpose of this paper is to explore the development of the internal temperature in the fire, high temperature on the deterioration of the steel components. Additional
cooling equipment - Fan, explore the effectiveness of
reducing indoor and surface temperature. Finally, compare with results by ANSYS analysis, explore the reason for the difference, the advantages and disadvantages in the operation between FDS and ANSYS.
Based on the results, prove that the vertical channeling of the heat from the fire source, then by the horizontal diffusion.,satisfy the effects of indoor thermal convection. Cooling equipment - Fan reduces the indoor temperature and extend the time to evacuate, FDS (Fire Dynamics Simulator) compared with ANSYS, better to get the temperature distribution of the real scene of a fire. ANSYS analyze the internal temperature of components, so both in the analysis have a good complementarity.
