摘 要： 本文通过实验研究了蓄冷系统的蓄冷及融冰特性。以水和硼砂水溶液做载冷剂的蓄冷系统为对象，分别讨论了其蓄冷槽温度变化、系统COP变化以及载冷剂温度变化等一系列参数。通过实验分析得到：一定质量分数的硼砂溶液较水更有利于蓄冷系统的蓄冷和释冷。 关键词 ：蓄冷槽；蓄冷；释冷；实验分析 Experimental Analysis Of Cool Storage And Discharging Characteristics In Ice Storage Tank Xin Tianlong Wan,Chao Liu Yicai Chen Siming Chen Kai Zhang Mingyan School of Energy Science and Engineering, Central South University, Changsha, 410083, China; Abstract : In this paper, experiment of cool storage and discharging characteristics in ice storage system was studied. The ice storage system which water and borax solution were secondary refrigerant was studied. A set of parameters such as temperature changes in ice storage tank， COP changes in the system and temperature changes of secondary refrigerant were discussed as well. It obtained through the experimental analysis that a certain mass fraction of the borax solution is more beneficial to cool storage and discharging than the water in the ice storage system.
