摘要


有關本研究是針對輕鋼架建物的溫度控制設計工法比較,以建立便一般非工程專業人士使用的簡易評量方式,研究的討論對象分別為隔熱材降溫與浮力通風降溫,在取得各項現地量測數據後,利用相關理論判斷各因素對降溫能力之貢獻,在輕鋼架建物的降溫與熱環境分析結果,可以觀察到有高度大的建物使用浮力通風系統降溫能力較佳及建物開口面積影響降溫能力大等結論。 本研究的成果,可降低一般民眾判斷輕鋼架建物降溫系統的專業門檻,利用案例數據分析,針對建物各性質對於浮力通風的影響,提出自製表格與各項目的比重做為建物降熱設計的初步參考依據,建議在利用浮力通風系統降溫時,除了可以利用各參數控制,建的合適的建物降溫效果外,應利用本研究建立之評估表與優缺點一覽表選擇合適的降溫方式,並注意浮力通風系統降溫時在滿足通風理論公式後,確認設計排風路徑應確實暢通

This research focuses on Light Metal Structure and compares different temperature control designs and methods in order to establish a simple evaluation system for public use. The heat-reducing methods compared in this study are Insulation material to cool and buoyancy ventilation to cool. After the acquisition of a series of on-site statistics, related theories were applied to evaluate their efficacy of heat-reduction. The analytical results in heat-reduction and thermal environment of Light Metal Structure shows that variables for preliminary system has a better heat-reduction rate on higher buildings, and that heat-reduction rate is influenced by Building aperture area. The results of this study lowers the Professional threshold for common people in evaluating Light Metal Structure’s heat-reduction systems. Numerical analyses were applied on case studies to evaluate the Building Materials’s influence on buoyancy ventilation, and a chart was hence made to weigh all variables for preliminary reference in heat reduction of a building. This study suggests that, when reducing heat with buoyancy ventilation, besides controlling each parameter and customizing building for heat-reduction, the evaluation chart in this study can also be used in selecting an appropriate heat-reduction system. It should also be noted that, when reducing heat with buoyancy ventilation, after complying with the theoretical formula of buoyancy ventilation Theory, the ventilation passage design should be checked for clearance.
