【英文篇名】 Determination of chiller capacity in ice storage systems 【作者中文名】 张杰; 李晓志; 刘树春; 【作者英文名】 By Zhang Jie★; Li Xiaozhi and Liu Shuchun ★Beijing Institute of Architecture Design; Beijing; China; 【作者单位】 北京市建筑设计研究院; 【文献出处】 暖通空调, Heating Ventilating 主机制冷量; 系统配置; 基载主机; 【英文关键词】 ice storage; chiller capacity; system configuration; base chiller; 【摘要】 通过对三种不同配置的冰蓄冷系统的逐时负荷和各节点载冷剂温度变化的详细分析,指出根据目前常用的公式计算出的主机制冷量在很多场合不能满足实际负荷要求。通过对这几种系统控制性能的初步比较得出主机上游且融冰优先的串联系统最有效,同时指出配有基载主机的蓄冰系统的负荷分配设计中需要注意的问题。 【英文摘要】 Analyses in details the hourly load relocation and glycol temperature for three different configurations of an ice storage system with the commonly-used formulas for determining the chiller and ice-tank capacity. Points out that the chiller capacity and ice-tank size determined by the formulas can not satisfy the actual load requirement on many occasions. Concludes that series system with chiller upstream and ice-melting priority is the most effective through a preliminary comparison of the control performa...
