相變材料用於混凝土中之力學及熱學行為

Abstract

近年來，地球暖化、環境汙染以及節能減碳是全球注目的焦點，而在生活上，電的使用為能源消耗的最大宗，又因全球氣溫逐漸攀升，夏季使用冷氣空調的耗能量也節節上升。 本研究利用相變材料有高潛熱性質，與一般的建築材料結合可以製成具有較高熱容的建築材料，致使維持舒適的室內溫度，減少冷氣空調的使用量，以達到節能減碳的效果。而相變材料的選用、相變材料如何與建築材料複合使用、相變材料於建築材料中含量的多寡等為溫度控制與調節的重要因素。 本論文將針對複合相變材料在永續節能上的研究與應用著手，從相變材料的選取與複合、相變材料的封裝方式、相變材料與建築材料的製備及其力學和熱學成效、BIM軟體模擬相變材料用於結構物中的效益，藉此找出最適合台灣地區氣候的複合相變材料設計與應用方式。

In recent years, global warming, environmental pollution, and carbon reduction are the focus of global attention. Electricity usage for daily lives is the largest energy consumption. The global temperature is gradually rising and summer use of air conditioning increases energy consumption. The use of high latent heat of phase change material property combining with general building materials can produce high heat capacity of construction materials that will maintain a comfortable indoor temperature, reduce the amount of air conditioning use, in order to achieve energy saving and carbon reduction. In order to select the use of phase change materials, it is necessary to know the important factors such as how to use building materials containing phase change materials, the amount of phase change materials content in building materials for temperature control. In this thesis, composite phase change material on sustainable energy-saving research and application is summarized. Selection of composite phase change materials and encapsulation methods, information on its mechanical and thermal behavior of phase change materials and building material are studied. BIM software simulations are performed to evaluate the effectiveness of composite phase change materials on thermal behavior of structures for climate control.
