One setpoint.
Up to 15% plant energy savings.

Most chilled water plants control condenser water temperature using static rules of thumb. This guide explains why the optimal setpoint is constantly moving, and how dynamic optimization captures saving conventional control strategies miss.

THE INSIGHT

The optimal setpoint is a moving target

A fixed rule of thumb gets close for part of the year. The rest of the time, it
quietly leaves savings on the floor. Three reasons why.

98%

Built for a day it never sees

Plants are sized for the worst afternoon ofthe year. For the other 98% of hours theyhave spare capacity, and free savingsavailable, if the setpoint follows theconditions.

Two coupled energy users

Colder water makes the chillers draw lessbut the tower fans draw more. The trueoptimum is the bottom of the combinedbowl, not either curve alone.

A rule of thumb sees one input

Wet-bulb plus a fixed offset is blind to load,chiller type, part load and staging, the verythings that move the optimum from hour tohour.
