| 中文摘要 |
工業革命的發展，將人類文明昇華至更高的領域，帶來的不僅是人類生活品質的提升，更是造就許多的就業機會。然而大部分的工廠其環境惡劣，長時間待在悶熱的環境下對人體有著不小的負擔。近年來，隨著人類對環境舒適性的重視，也驅使不少的專家想方設法來解決工作環境之舒適性。本研究透過CFD對廠房散熱模型進行模擬，將窗戶與排風扇的開關作為變數，來模擬出最佳化的散熱模型。結果顯示當窗戶打開而氣窗關閉的時候，輔以排氣扇（V=2m/s）會有最佳的散熱效率；若只靠自然對流的方式進行散熱，則窗戶及氣窗全開是最佳的散熱模型。 |
| 英文摘要 |
The development of the industrial revolution has sublimated human civilization to a higher level, which not only improves the quality of human life, but also creates many employment opportunities. However, the environment of most factories is harsh, and staying in the sultry environment for a long time has a lot of burden on the human body. In recent years, as human beings attach importance to the comfort of the environment, many experts have also been driven to find ways to solve the comfort of the working environment. In this study, CFD is used to simulate the heat dissipation model of the factory building, and the windows and exhaust fans are used as variables to simulate the optimal heat dissipation model. The results show that when the windows are open and the louvers are closed, the exhaust fan (V= 2 m/s) will have the best heat dissipation efficiency; if only natural convection is used for heat dissipation, then the windows and louvers are fully open is the best heat dissipation model. |
