本报告介绍了达拉斯/沃斯堡（D/FW）机场单个部件和整个冷却系统的性能和控制特性的调查结果。一个目标是确定电厂设备的适当计算机模拟模型，用于评估系统改造和适当的控制策略。D/FW数据采集系统提供了大量数据，用于验证组件模型。第二个目标是记录使用变速控制的冷水机组与使用叶片控制的定速冷水机组的性能差异。研究了D/FW冷却系统的性能和控制特性。最后，开发了可用于设备在线优化控制的方法。

This report presents results of an investigation of the performance and control characteristics of the individual components and the cooling system as a whole at the Dallas/Fort Worth (D/FW) airport. One goal was to identify appropriate computer simulation models of the plant equipment to be used in evaluating system retrofits and proper control strategies. Much data was available from the the D/FW data acquisition system for validating the component models. A second goal was to document the performance differences associated with the use of chillers operated with variable speed control with that for fixed speed with vane control. The performance and control characteristics of the D/FW cooling system were also studied. Finally, methodologies useful for on-line optimal control of the equipment were developed.
