摘要

近年來能源危機、環保意識抬頭，積極推廣綠建築下，相變材料之應用也成為重要的討論一環，相變材料具有高潛熱之特性，添加於建築物混凝土中，可協助外牆在白天熱能傳遞室內時吸收大量能量與室內溫度攀升延遲，達到空調使用量之減少、二氧化碳排放量降低；本論文之研究分為兩大部份:

1.相變材料之微膠囊封裝
本論文主要研究以微膠囊化封裝相變材料掺入混凝土中之熱學行為，且配合未來欲嘗試之相變新材料應用，可自行封裝探討；採用在微膠囊封裝上為常見之封裝方法:原位聚合法與懸浮聚合法個別分析其優缺點。

2.MPCM-28D之新拌混凝土試驗與ABAQUS軟體模擬
使用正18烷微膠囊化粉體為掺料，拌合微膠囊混凝土觀測其熱學性質，分析在不同之添加量下熱能吸引效益與延遲能力做一探討，配合軟體ABAQUS分析進一步計算量化添加量帶來之優點比較。

In recent years, due to the energy crisis and the rise of environmental awareness, the application of Phase Change Material has become an important topic of discussion while promoting green building. Phase Change Material has the characteristics of high latent heat. Adding it into the concrete of building material could help the exterior wall to absorb large amounts of heat energy and to retard the rise of indoor temperature in daytime when heat transferring into indoor area, in order to achieve the reduction of power consumption of air conditioning and emancipation of carbon dioxide. This study is divided into two parts:
1.Microcapsule encapsulation of Phase Change Material
This thesis mainly studied the thermal behavior of the microencapsulated Phase Change Material mixed with concrete. Therefore in the application of new Phase Change Material in the future, we could study with self-encapsulated Phase Change Material. Moreover, this research use the common encapsulation method: in situ polymerization and suspension polymerization, and discussed their advantages and disadvantages respectively.
2.Experiment of concrete contain with Phase Change Material
This thesis studied the thermal properties of concrete contain with encapsulated Phase Change Material, which use MPCM-28D as addition, and discussed the capability of heat absorbtion as well as the retardation ability with respect to different amount of addition. Meanwhile, this study further analysed and quantified the advantage of different amount of addition with finite element software ABAQUS.
