It is produced in machines called chillers and then pumped through air-handlers in each building to cool the air. Currently there are approximately 25,000 tons of cooling capacity serving twelve million square feet of building space. We have 40 chillers in 28 locations throughout campus. Until recently, chiller systems were installed in all new buildings. Now distributed central chilled water plants are being established, and buildings are being connected together to form a chilled water loop.
Older equipment is removed and new more efficient chillers are operated to serve numerous buildings.
Currently, chilled water loops are established on the White Campus, Red Campus and the Ag. These loops serve 50 buildings and include over five miles of underground piping.
