초록

본 연구에서는 잠열온도 조절에 관한 이론과 상변화 잠열재의 결정핵형성이론 그리고 PCM 결정화 모델을 정립하고, 농산물 저온 저장에 이용할 수 있는 냉축열 잠열재로 $H_2O$를 선정하여 NaCl을 온도 조절제로 잠열온도를 조절하였으며, 상변화 사이클에 의한 열특성 변화 추이와 물성의 안정성을 실험적으로 분석하였다.

The theory on phase change temperature control and nucleation of PCM was suggested in this research. The crystallization model of PCM was established. And H2O-NaCl mixtures were selected as cold storage materials for agricultural products and thermo-physical properies of the PCM were analyzed with experimental processes including freeze-thaw cycles.
