摘要

隨著環保意識逐漸高漲，節約能源的觀念更應落實於生活當中，以往過度依賴機械設備所創造的環境是不符合時代潮流，相信以誘導式設計手法創造舒適環境才是提供永續發展的平台之一，台灣地區擁有良好的自然通風環境，但許多建築因通風不良會造成健康與能源上損失，因此若能利用自然通風方式增加室內換氣率將有助於移除與稀釋室內污染物質，本研究之探討對象乃以居住空間為主，嘗試利用垂直型通風管來改善室內空氣品質。
為瞭解通風管的實際效能，本研究先以風洞實驗量測風洞中之風梯度與通風管於受風力及綜合作用(風力加浮力)下，對開口內外壓力變化影響，實驗結果將有助於計算流體力學程式Computational Fluid Dynamics (CFD)的設定參考與比對，CFD與風洞實驗之比對方式是將風洞實驗段重建於計算流體力學程式中，並經由改變紊流模型、邊界條件、網格數及模型位置方式來取得與實際流場最接近的設定值，待完成比對後其它變因探討皆於CFD中完成。
本研究之實驗結果將影響通風管的設計因子包括；高度、寬度、進風口壓力及室內熱收量多寡，實驗結果將可成為未來建築設計者欲採用通風管通風時之參考，藉此提升室內空氣品質。

Due to the shortage of energy and the deterioration of the living environment, the importance of concerning energy uses for building design is aware. To achieve the thermal comfort by passive design is one of the common strategies for “green building”

The study aims at proving prove the influence of the different parameters of vertical ventilation duct in Taiwan’s dwelling unit. Furthermore the study is looking at the performance of improving IAQ and the ability of energy saving.

In this work the wind tunnel experimental method was used to generate the data of boundary condition .The wind tunnel experiment data was used to compare with the CFD simulation results which is called validation. After the validation, it is then to begin the parameter study for the performance of ventilation by vertical ventilation duct.

The research results is affected by geometry of the vertical ventilation duct which include height, width, inlet pressure and heat gain. The simulation can be used for the architects designing naturally ventilated building with the vertical ventilation duct.
