为了提高能源效率并促进中央设备的更好管理，许多冷冻水系统设计为根据负荷改变流量。这些系统通常不使用三通阀和旁通管。尽管流量旁通元件已被消除，但其中许多系统仍无法控制与负荷相关的流量需求。惩罚是更高的能源使用和更难管理的冷冻水泵设备。本文旨在介绍控制冷冻水盘管的改进方法，并在实际应用中演示这些方法。引文:德克萨斯州休斯顿ASHRAE学报第88卷第1部分

To increase energy efficiency and promote better management of central plant equipment, many chilled water systems are designed to vary flow in relation to load. Three-way valves and bypass piping are generally not used in these systems. Even though the flow bypass elements have been eliminated, many of these systems are still unable to control flow demand in relation to load. The penalty is higher energy usage and more difficult management of chilled water pumping equipment. The purpose of this paper is to introduce improved methods for controlling chilled water coils and demonstrate these methods in an actual application.
