Experimental analysis on heatstorage and discharge characteristics with formstable phase change material

Experiments heatstorage and discharge characteristics in a heatstorage tank filled with formstable phase change material(PCM) and water as heat transfer fluid (HTF). Studies the effect of verifying the velocity， flow direction and inlet temperature of HTF on heatstorage and discharge characteristics of heatstorage tank. The flow direction is from up to bottom in the heatstorage process， and the flow direction is from bottom to up in the discharge process. The inlet temperature and velocity affect heatstorage and discharge time， but inlet temperature affects more.
