【英文篇名】 Mathematical model of encapsulated ice storage 【作者中文名】 李先庭; 赵庆珠; 李吉生; 彦启森; 【作者英文名】 Li Xianting; Zhao Oingzhu; Li Jisheng and Yan Qisen; 【作者单位】 清华大学; 【文献出处】 暖通空调, HV 冰蓄冷; 数学模型; 模拟; 【英文关键词】 encapsulated ice storage; spherical capsule; mathematical model; simulation; 【摘要】 给出了冰球式蓄冰罐蓄冷和取冷过程的数学模型。该模型考虑了载冷剂与冰球间的相互作用、冰球的相变换热特性以及蓄冰罐的热损失。编制了求解程序ＳＴＡＩＴ，利用该程序计算了８个不同的蓄冷和取冷工况。对比结果表明，利用ＳＴＡＩＴ模拟的结果与实测结果非常接近。 【英文摘要】 Presents a mathematical model describing the freezing and melting processes of the ice-storage container with encapsulated ice in spherical capsules and oonsidering the Interaction between gtycol and the capsules, the heat exchange performance of the capsules and the heat loss of the ice-storage container. With a computer prosramme caf led STAIT developed to solve the model, simulates several cases including freezing and melting processes, and compares predicted results and experimental ones and shows a goo...
