Whether they are cooling oil in an injection molding machine or supplying cooled water to bakeries, chillers play an important role in the HVAC (Heating, Ventilation, and Air Conditioning) systems of commercial and industrial facilities. A chiller is a mechanical device that facilitates the heat exchange from water to refrigerant in a closed-loop system.
A water-cooled chiller is an energy efficient alternative to air systems that use chemical refrigerants. These systems do not require an open outdoor space and are more stable than air systems. However, it is important to remember that the piping and chiller cooling tower must be properly maintained in order to prevent corrosion from occurring.
Chilled water-based systems also allow for less total interior ductwork than all-air systems. This is because it is impractical to pump liquid coolants all around a large, multi-story building to multiple air handlers. Long runs of coolant pipes increase the probability for leaks to occur that would create a hazardous work environment; pollute the indoor environment; and waste money.
The University’s chilled water system pumps up to 100,000 gallons of chilled water per minute through a loop piping system that distributes it to buildings through bridge interface systems. In addition, the chilled water plant manages eight standalone chillers that serve individual building campus systems that cannot be served by the loop piping system. The combination of these systems allows the University to meet peak cooling demands while reducing energy consumption, environmental impact, and overall cost of ownership. water chiller unit
