The liquid phase change material at the top is then displaced by the newly-formed phase change material falling to the bottom. In the second mode, which uses a melt cycle, heat exchange fluid is given to the lower passageway to melt the phase change material at the bottom, causing the newly-formed liquid phase change material to be displaced towards the top.
