摘要
针对在设计蓄冰工程时普遍存在优化蓄冷比来确定蓄冰主机容量的做法和确定蓄冰工况的问题 ,提出蓄冰冷机的蓄冰运行工况应根据制冷机组的类型和拟采用的蓄冰方式来确定。通过分析计算给出了蓄冰主机在全蓄冷模式、部分蓄冷冷机优先模式、部分蓄冷释冷优先等 3种控制模式下确定冷机容量的计算式 ,并得出了在不同的控制模式下冷机的容量不受蓄冷比影响的重要结论。说明了蓄冰工况和冷机容量的正确选定对合理地设计蓄冰系统有非常重要的作用 。
How to optimize ice storage fraction and determine ice making mode a common method of selecting capacity of chillers now. In view of this situation, a new kind of method on determining of ice making mode of chiller is introduced according to types of chiller and ice storage. Formula of capacity of chiller are given under the full storage, partial storage and chiller priority control, partial storage and ice priority control. The important conclusion that ice storage fraction is independent on capacity of chiller under specified control is obtained. It is very important to determine properly capacit of chiller and ice making mode in order to design reasonably ice storage system. An engineering example is discussed in detail.
