Abstract

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.

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.
