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。
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 good fit of them.
