冰蓄冷系统中主机制冷量的确定
Determination of chiller capacity in ice storage systems
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。
Abstract：
Analyses in details the hourly load relocation and glycol temperature for three different configurations of an ice storage system with the commonlyused formulas for determining the chiller and icetank capacity. Points out that the chiller capacity and icetank size determined by the formulas can not satisfy the actual load requirement on many occasions. Concludes that series system with chiller upstream and icemelting priority is the most effective through a preliminary comparison of the control performances among several systems. Points out the problems deserving notice about the load proportioning in ice storage systems with a base chiller.
