相變材料性能及應用於節能建材之研究

Abstract

根據統計，建築物是世界上最大的能源消耗者之一，其消耗的能源和釋放的溫室氣體占全世界能源總消耗量的25%到33%。在追求永續發展的目標下，具備有建築節能功能之相變材料在未來勢必將扮演一個重要的角色。然而，相變材料如何嵌入建材中，以及建材中相變材料含量的多寡，還有相變材料的選用等多項因素亦成為溫度控制與調節的重要因素。 因此，本篇論文分為三大部分： 1. 對於相變材料的分類、運作原理、加工方法、選用原則、應用方式以及近代發展趨勢作一系列的探討。 2. 關於相變材料嵌入建材中的研究，其內容包括適合本地的相變材料篩選、相變骨材的製作、相變砂漿的配比設計以及相變砂漿牆體控溫試驗。 3. 藉著功能完善的軟體分析，模擬相變材料在多種環境條件下的運作狀況，藉以探討其熱學性質與帶來的效益。其分析的內容包括軟體分析合理性之驗證、隔熱與控溫的差異、不同相變材料含量的影響、控溫效果與溫差的關係以及模擬實際環境應用之節能效益評估。

According to statistics, the building is the world's largest energy consumer, its energy consumption and greenhouse gas emissions reach to 25% - 33% of the world's total energy consumption. In the pursuit of sustainable development objectives, the phase change materials with a building energy-saving features is bound to play an important role in the future. However, how to embed phase change materials into building materials, the amount of phase change materials toward building materials as well as the selection of phase change materials are also a number of vital factors to the temperature control and regulation. Therefore, this paper is divided into three parts: 1. A series of study of the classification of phase change materials, operational principles, processing methods, the principle of selection, application methods and modern trends . 2. The research about how phase change materials embedded in the building materials, which includes selecting phase change materials for the local screening, aggregate production of phase change, phase change of mortar mix design and testing phase transition temperature mortar wall. 3. Through functional analysis of software to simulate phase change materials in a variety of environmental conditions of operation, with a view to explore the thermal properties and benefits. The analysis includes analysis of the reasonableness of the verification software, heat and temperature differences, different levels of phase-change material, temperature effects and the relationship between temperature and simulate the actual environment the application of energy efficiency evaluation.
