摘要

許多人認為，巨蛋與捷運系統，都是現代都市的要件之一。以往巨蛋設計者以本身的經驗從事設計施工，從現場測試中獲得設計經驗。也有學者進而採用縮小尺度模擬方式試驗較複雜的空間，以確保成果符合環境需求。但小尺度實驗無法以單一測試完成設計所需數值，故如以等溫環境從事氣流模擬。臺灣因巨蛋發展僅為數年之久，並無巨蛋空調及節能相關研究。而氣流模擬軟體成熟並應用於建築室內環境設計，亦為近年來的研究成果，故目前僅北京體育館模擬氣壓及氣流情形。
本文以空調負荷軟體計算整體空調負荷，並採用不同方式進行節能分析，其中以分層(成層)空調方式較採用全面空調方式可節省26%以上的空調負荷量。空調系統加入全熱交換器可再降低25.7%以上的空調負荷量。
本文另以氣流模擬分析軟體進行全尺度氣流模擬，建立最佳化氣流方式，降低空調送風區域，減少送風量，降低空調負荷。測試結果顯示以側吹迴旋氣流最適合應用於體育環境。而下吹式出風方式有最佳溫度環境較適合應用於非球類運動及商業用途。因巨蛋興建以體育運動為主，故採可變側吹式出風口可獲得最佳運動環境及次佳之商業環境。

Hundreds people believe dome and mass rapid transit system are one of the elements for modern city. In the past, the dome designer takes advantage of his personal experience from design construction and on-the-spot test to build the design experience and revise the design value eventually. In order to test more complicated space and ensure the outcome meets up with the environmental requirments, it was used a scale-down way to simulate by some scholars. Although the small scale experiment is unable to achieve all the figures by united testing, people try to take unit figure testing such as engage in air current simulation at the consistency temperature environment. Due to the dome development in Taiwan is only for few years, there is no sufficient research relative to air-condition system and energy-conservation of dome. Meanwhile, except of the Olympics host country was building dome around oversea, there is no giant gymnasium construction to be presented obviously. Currently the CFD (Computational Fluid Dynamics) software was applying to indoor environment design of the architecture maturely, it was the research contribution as well at these few years. Nowadays, only Beijing gymnasium keeps simulate air pressure and air flow situation, however, it still not be allowed to simulate air flow within full scale, and to probe into different air current influence on indoor environment. 　
The dissertation aims to calculate the cooling load by cooling load software and process energy-conservation through different methods. Narrowly speaking, it could save more than 26% cooling load volume if takes layer mode, it means it could save building and operation charge at the same time. Moreover, the air-condition system joins with heater exchange, it could decrease down 25.7% cooling load volume at least.
For the other main point of this dissertation is processing full-scale CFD (Computational Fluid Dynamics) by CFD software, and build the optimum air flow to reduce air supplier and cooling load. The testing result indicates spiral mode air flow is proper to applying in gymnasium environment. Now from the gymnasium taking spiral mode air flow mainly also could prove this evidence. On the other hands, drop mode air flow has the optimum temperature environments, better to applying in non-sport and commercial intended use. Due to the dome is built for the sport or exercise particularly, there it could take variable volume system control air supplier angle to ensure the best sport environment and inferior commercial environment.
