The University has one of the most
sophisticated chilled water generating systems in the world.
Chilled Water, which is used to cool buildings and equipment, is
provided by either the District Cooling Systems comprised of a network
of chiller plants and underground piping or by stand alone chillers
dedicated to individual buildings.
The District Cooling System for the
main campus consists of five chiller plants with a combined capacity of
50,000 tons. The plants are interconnected by underground piping
and operated as one production system using a networked Supervisory
Control and Data Acquisition (SCADA) system. From a single
console, operators can manage and balance loads among the chiller
plants, use capacity anywhere in the system and continue operating in
critical areas despite cooling equipment failure or utility
outages.
Two of the chiller plants house both
steam absorption and electric centrifugal chillers; the other three
house only electric centrifugal chillers, allowing us to quickly
respond to outages of either energy source, as well as manage costs by
monitoring the local electric utility’s hourly pricing program.
