带基载主机的冰蓄冷系统在部分负荷工况下运行模式的探讨

Discussion on Operation Mode at Part Load for an ITS System with a Base Chiller

通过实例分析说明,当基载主机的“综合容量”大于单台双工况主机的“综合容量”时,在所有部分负荷工况下应优先关闭基载主机而不是双工况主机;当基载主机的“综合容量”小于等于单台双工况主机的“综合容量时”,在大部分的负荷工况下也应优先关闭基载主机,这样就能节省系统能耗。

By studying an example, point out that base chiller should be stopped in priority when the ＂integrated capacity＂ of a base chiller is greater than that of dual duty chiller at all part load conditions and when the ＂integrated capacity＂ of a base chiller is less than or equal to that of dual duty chiller, base chiller should be stopped too at most part load conditions. This strategy will achieve the saving in system energy consumption.
