than at full load. Variable frequency drives for unloading tower fans and chilled-water pumps may provide benefits, depending on the costs, system operating hours, system type, and outdoor air conditions. (See “System Controls” on page 87.)

In addition to the design decisions faced by the small chilled-water system designer, the following objectives may be encountered by the mid-sized system designer.

Managing control complexity

As chilled-water systems get larger (Figure 18), control system design and execution become more critical and more complex. There are simply more combinations of equipment and operating scenarios. On the other hand, systems this size generally have more highly-skilled operators who can understand proper operation and maintenance. To help operators understand expected system operation, chiller plant controls are usually more customized and sophisticated.

Preferential vs. equalized loading and run-time

With more chillers, sequencing options might include preferentially loading the most efficient chiller or equalizing the run time of chillers. The decision hinges on how different these chillers are and the preferred maintenance routine. For example, a chiller plant with one quite old—though still reliable— chiller may periodically enable that chiller to ensure it continues to function,
