摘要(Abstract):

对比分析了美国Calmac牌 1 1 90A型蓄冰筒和清华人环公司RH -ICU系列冰盘管这两种具有典型融冰特性的蓄冰设备 ,根据某办公楼和宾馆选用这两种蓄冰设备的需要 ,由计算机模拟出 4个部分冰蓄冷系统的优化方案 ,以标准年 5~ 9月的动态负荷为基础 ,对比分析了各方案的蓄冷率 (ISF)和运行费。阐明了在选用蓄冰设备时 ,应注意使融冰特性和用户负荷分布特点相匹配 ,这样才能充分发挥其移峰填谷的作用来降低系统运行费。
Two kinds of ice-storage tanks (calmac 1190A tank, U.S.A and RH-IW tank, Tsing hua RH CO.) with different typical performance of ice-melting are analyzed and compared, and these tanks are used in ice-storage AC system for one office building and one hotel building. Four optimal schemes are obtained through computer simulation. Based on dynamic cooling loads of the standard year, the ISF (ice-storage factor) and the operating cost are analyzed and compared.
