Event: VSHE Blue Ridge District Meeting  

Date: Thursday, August 22nd, 2019 

Time: 2-4 PM

Location: TBD

Topic: Chiller Plant Optimization and Energy Efficiency

Abstract: 

 

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 set points 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
