【英文篇名】 Experimental analysis on heat-storage and discharge characteristics with form-stable phase change material 【作者中文名】 李香玲; 陈超; 蹇瑞欢; 欧阳军; 【作者英文名】 By Li Xiangling; Chen Chao; Jian Ruihuan and Ouyang JunBeijing University of Technology; Beijing; China; 【作者单位】 北京工业大学; 【文献出处】 暖通空调, Hv 实验; 蓄/放热特性; 【英文关键词】 form-stable PCM; experiment; heat-storage and discharge characteristics; 【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。 【英文摘要】 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...
