基于设计周期负荷的冰蓄冷系统设计
Ice storage system design based on cooling load of design period
摘要：
通过对三种不同类型建筑的负荷分析，指出以一个周期（通常大于1 d）的逐时负荷，即设计周期负荷，代替设计日逐时负荷进行冰蓄冷系统的设计更能反映普遍情况。以设计周期负荷为基础，建立了满足室内空调要求的最小制冷主机容量的计算方法，给出了相应蓄冰槽容量的计算方法。应用算例表明，采用基于设计周期负荷的冰蓄冷空调系统中的制冷主机容量通常会比传统设计方法的容量小30%～50%。

Abstract：
According to the analysis of the hourly cooling load of three kinds of typical buildings, points out that designing ice storage system based on the cooling load of design period rather than one day is more general. Based on the cooling load of design period, develops the algorithm to get smallest capacity of chillers and the capacity of ice tank. Several cases studies show that the capacity of chillers based on the cooling load of design period is generally 30% to 50% less than that based on the cooling load of design day.
