This session will present a case study of how one hospital identified design and operational flaws in their chiller plant. The flaws were analyzed, quantified, and tuned into a 12 percent reduction in operational cost. Attendees will learn how less than optimum operational performance created an opportunity that lead to a high efficiency chilled water plant.
Describe how automated staging of chillers is based on full load amps and secondary chilled water temperature
Use cooling towers and variable frequency drives to maintain condenser water setpoints with programming changes based on outdoor air temperatures
Explain how differential pressure control is based on chilled water valve positions
Describe the theory of free cooling from plate and frame heat exchanger and the effect that it can have on energy conservation
