Multiple-Chiller-System Design and Control

Effect of chilled-water flow rate Since the evaporator is a heat exchanger, it is sensitive to water flow rate. Excessive flow may result in high water velocity, erosion, vibration, or noise. Insufficient flow reduces heat-transfer efficiency and causes poor chiller performance. Some designers have concerns over low flow rates causing fouling.
