平板蓄冷器蓄冰过程实验研究 【英文篇名】 Experiment of charging process in a flat and rectangular ice capsule 【作者中文名】 方贵银; 李平; 【作者英文名】 By Fang Guiyin and Li Ping; 【作者单位】 中国科学技术大学; 合肥市计量测试研究所; 【文献出处】 暖通空调, Hv 实验装置; 过冷; 成核剂; 【英文关键词】 ice storage; experiment device; supercooling; nucleation agent; 【摘要】 在自行研制的实验装置上研究了平板内的蓄冰过程 ,得出了载冷剂进出口温度和蓄冷剂温度随时间的变化规律 ,并研究了蓄冰中的成核过程 ,通过添加人工成核剂可减小冰蓄冷过程的过冷度 ,从而提高蓄冰主机的效率。 【英文摘要】 Investigates the charging process on the experiment devices developed by the authors and obtains the correlations revealing variation of the secondary refrigerant temperatures at inlet and outlet and the cool storage agent temperature with time. Also examines supercooling and nucleation of water inside the flat and rectangular capsule during the charging process and finds it helpful in reducing the supercooling degree to add a nucleator into water so that raising the efficient of the ice making chiller.
