智慧溫感外牆之隔熱應用研究

Application of smart temperature-controlling building envelope for thermal insulation

臺灣目前大部分的建築結構體材料為鋼筋混凝土，但鋼筋混凝土有高蓄熱及熱導性，使建物在面臨日益嚴峻的外部熱環境時，維持舒適的溫控環境日益困難，除了造成額外能源消耗，亦對特定使用者身體健康造成威脅，更因溫差頻繁導致混凝土結構收縮，對結構體壽命造成不良影響。本研究將電熱晶片導入智慧溫控外牆，透過預埋入外牆之銅管溫控模組及智慧溫感建材，來執行智慧間歇性反趨點對流模式判斷，藉此讓溫控調節器對牆體進行溫度控制。經實驗後證實智慧間歇性反趨點對流模式為較佳的供應時域及換氣頻率模式，若使用此模式可增加熱交換時間，相較瞬時熱交換情境可增加一倍的降溫效果，目前在致冷溫控最佳可控制牆體降溫2℃的效果。

Most buildings in Taiwan were built with reinforced concrete, a material with high heat storage capacity and thermal conductivity. In the face of an increasingly severe external thermal environment, sustaining a comfortable temperature-controlled environment in these buildings has become increasingly difficult, which not only leads to extra energy consumption and health risk to specific users, but also causes reinforced concrete structures to contract because of frequent temperature variations, thereby exerting an adverse influence on their structural life. In this study, thermal electrical chips were incorporated into smart temperature–controlling building envelope. Copper tube temperature–controlling modules and smart temperature information materials that were pre-embedded in the building envelope were employed to calculate the timing for implementing the smart intermittent inflection point convention model, thus enabling temperature adaptive regulators to control wall temperatures. Experimental results verified that the smart intermittent inflection point convention model provided a relatively satisfactory supply time domain and ventilation frequency mode and could extend heat exchange time. In comparison with instantaneous heat exchange scenarios, the cooling effect of the proposed model could be doubled. The current optimal cooling effect could lower wall temperatures by 2°C.
