中文摘要

本研究發展了一個適用於台灣氣候的風壓通風計算模式TAIVENT(Taiwan Natural Ventilation Model),模式結合了台灣中央氣象局的氣象資料(平均風速、盛行風向、氣溫、濕度),計算各種建築物座向、室內隔間、開口位置、大小及是否有裝紗窗、百葉窗或外推窗的風壓通風量。並利用內政部建築研究所的風洞實驗室及多頻道壓力掃瞄計量測得通風模式所需之建築物表面風壓,再使用二維的立方弧線法內插求得建築物表面任意一點的壓力。此外TAIVENT模式利用牛頓-拉福森法求取各個房間的室內壓力及各開口的通風量,研究結果顯示若建築物表面的風壓係數為已知,可以利用TAIVENT模式計算周遭建築物對風壓通風的影響。建築師可利用TAIVENT模式找出最能配合當地氣候條件的建築通風設計,充分地利用自然通風來維持舒適的室內環境。

英文摘要

This study developed a multizone ventilation model TAIVENT to calculate the air exchange rate for typical residential buildings in Taiwan. The ventilation model is based on the mass conservation and orifice equation to calculate the wind-driven ventilation. The weather data (wind speed, wind direction, air temperature and humidity) from the Central Weather Bureau were analyzed and used for the model. The pressure distributions around a rectangular building under various wind directions were measured by wind tunnel experiments and interpolated by a two-dimensional cubic-spline method. Besides, the TAIVENT model uses the Newton-Raphson method to calculate the room pressures and flow rates through each openings.
