Abstract
Abstract A numerical analysis of solid-liquid phase change was performed on a heat transfer module which consisted ofcirculating water path (BRINE), heat transfer plate (HTP) and phase change material (PCM) layers, such as high temperature PCM (HPCM, 78~79°C) and low temperature PCM (LPCM, 28~29°C). There were five arrangements, consisting of BRINE,HTP, LPCM and HPCM layers in the heat transfer module. The time and heat transfer rate for melting/solidification wascompared to their arrangements, against each other. As results, the numerical time without convection was longer than the experimental one for melting/solidification. Moreover, the melting/solidification with the BRINE Ⅰ -LPCM-BRINE Ⅱ - HPCMarrangement was faster(10 hours) than the others; HPCM-BRINE-LPCM, BRINE Ⅰ -HPCM-LPCM-BRINE Ⅱ one.
