填充板状定形相变材料蓄热槽蓄/放热特性实验研究
Experimental analysis on heatstorage and discharge characteristics with formstable phase change material
摘要：
对填充了板状定形相变材料、以水作为热媒的蓄热槽的蓄/放热特性进行了实验研究；重点考察了热媒的流速、流动方向及进口温度的变化对蓄热槽蓄/放热特性的影响，认为在蓄热过程，热媒在蓄热槽内的流动方向宜上进下出，放热过程则相反；热媒进口温度和速度对蓄热槽的蓄/放热时间都有影响，前者的影响更为显著。

Abstract：
Experiments heatstorage and discharge characteristics in a heatstorage tank filled with formstable 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 heatstorage and discharge characteristics of heatstorage tank. The flow direction is from up to bottom in the heatstorage process， and the flow direction is from bottom to up in the discharge process. The inlet temperature and velocity affect heatstorage and discharge time， but inlet temperature affects more.
