Energy Optimization at Mission Critical Facilities: Oakridge National Laboratory and Christ Hospital

08-10-2017 11:37

Summary

We will describe the results of several energy optimization studies that we have accomplished for mission critical chiller plants at Oak Ridge National Laboratory in Tennessee, and at Christ Hospital in Cincinnati, Ohio. We will describe how a chiller plant's energy consumption changes at the component level when the chilled water supply set point is increased. We will show:

1) How high temperature supply water is generated with heat exchangers and cooling towers in order to reduce chiller run time.
2) How to maintain low basin temperature for a smooth transition between chillers and free cooling heat exchangers.
3) The effect of cooling tower set-point on plant energy consumption.
4) The advantages of variable speed pumping of condenser water relative to constant speed pumps.
