상변화 물질을 이용한 자연형 태양열시스템의 축연성능에 관한 연구 ( A Study on the Heat Storage Performance of Passive Solar System by using Phase Change Materials )

Both architectural and thermal problems of sensible heat storage in existing passive solar system can be solved by Phase Change Material Storage (PCMS) which uses magnanimous heat of fusion for its storage. This study deal with not only the architectural application of PCMS, but the PCM-wall using PCM. After figuring out of the heat storage and melting fraction of a day during the heating period by giving changes to PCM and thickness of PCM-wall, they were compared to the heat storage of 25cm-thickness masony wall.
