本研究提出對於鐵皮廠房內部設置大型發電機並且設計以太子樓形式進行正壓通風散熱的最佳化研究，一般的鐵皮工廠的通風手段大多是使用通風球的熱浮力原理排放廢熱或是利用於進風及排風口設置通風扇以機械通風方式循環室內空氣，而本研究想要探討適合此廠房建築在容許的溫度規範下，通過模擬軟體ANSYS Fluent來推演在台灣的氣候環境下合適的進風設計方案。
本研究著重於室內的環境溫度，通過數值模擬軟體的方式找出最為節能且合適的模擬結果，其研究結果顯示，室內環境溫度因為進風口設置的數量不同而有所變動，通過兩種大氣條件，比較各個配置下的室內環境溫度與規範之差異，最後再將其結果選定差異最小的配置，以不同的進風量比例的推演，以整體室內平均溫度及最高溫度得出最為理想的進風設計結果，從本研究結果可以獲得作為廠房建築在面對室內環境散熱上的參考依據。

This study proposes to optimize large generators inside the iron sheet factory and design it as a covered ridge with sidewall openings for positive pressure ventilation and heat dissipation. The general ventilation methods of the iron sheet factory are to use the thermal buoyancy principle of the ventilation ball to discharge waste heat or use The intake and exhaust vents are equipped with ventilating fans to circulate indoor air through mechanical ventilation, and this study wants to explore the suitable temperature for the plant building, and use the simulation software ANSYS Fluent to infer the appropriate air intake in Taiwan climate environment Design.
This study focuses on the indoor ambient temperature, and finds the most energy efficient and suitable simulation results through numerical simulation software. The study results show that the indoor ambient temperature varies due to the number of air inlets. Through the two atmospheric conditions, compare the difference between the indoor ambient temperature and the specifications under each configuration, and finally select the configuration with the smallest difference to perform the deduction of different air intake ratios. The most ideal air intake design results are obtained from the overall indoor average temperature and the maximum temperature. The results of this study can be used as a reference basis for factory buildings facing the indoor environment in terms of heat dissipation.
