상변화온도가 다른 PCM을 혼입한 마감재의 적층시공에 따른 벽체의 열전달 성능 평가에 관한 연구

Abstract

To evaluate energy reduction possibility of finishing material by hybrid finish system in winter and summer season, PCM(Phase Change Materials), a material which shows heat control performance and separate phase change temperature, specifically n-Hexadecane(18℃PCM) and n-Octadecane(28℃PCM), was used by mixing and applying it as lamination to a finishing material in accordance with its mixture ratio to measure temperature change of out of the wall. As a result, 4:6 composition ratio of n-Hexadecane(18℃PCM) : n-Octadecane(28℃PCM) showed the most excellent thermal performance in terms of whole specimen in winter and summer season. Also, According to type of finishing materials in which PCM that has separate phase change temperature is mixed, coating material was firstly ranked as the most excellent in thermal performance in winter and summer season and the next was remitar and dryvit.
