Hydronic Systems Optimization
Client: Denver International Airport
Completion Date: Design: April 2011; Construction: April 2012
The purpose of this project was to reduce airport energy consumption by improving hydronic pumping efficiency and eliminating any flow-limited operation of equipment throughout the facility.
After developing a flow model of the hydronic heating and cooling systems, it was determined that installation of new pressure-independent control valves would allow removal of more than 125 pumps from the system. The project will produce an estimated annual energy savings of $400,000 for the airport and allow better access to the plant's full chilled water cooling capacity.
