本文推荐了在新的和现有的可变流量循环冷却系统中实现高（即15°F（8.3°C）或更高）冷冻水温差（DTs）的实用方法。一旦实现高冷冻水DTS，每加仑（升）分配的冷冻水将实现更多Btu（J/s）的冷却（图1）。在现有的循环冷却系统中，压力损失和泵送能量将大幅下降，新的循环冷却系统中可能会安装更小的泵和管道。此外，冷水机组将不再受最大蒸发器流量的限制，冷冻水储水箱将储存更多吨小时（MJ）的冷却水。 这种基本方法为可变流量循环冷却系统的性能提供了显著、持久的改进。单位:双引文:研讨会论文，大西洋城，2002年

This article recommends practical methods for achieving high, i.e., 15°F (8.3°C) or greater, chilled water temperature differentials (DTs) in new and existing variable flow hydronic cooling systems. Once high chilled waterDTs are realized, more Btu's (J/s) of cooling will be accomplished per gallon (liter) of chilled water distributed (Figure 1). Pressure losses and pumping energy will decline considerably in existing hydronic cooling systems, and smaller pumps and piping may be installed in new hydronic cooling systems. Also, water chillers will no longer be limited by maximum evaporator flow rates, and chilled water storage tanks will store many more ton-h (MJ) of cooling. This fundamental approach provides significant, enduring improvements in the performance of variable-flow hydronic cooling systems.Units: Dual
