Aline Wilmot Skaggs Biology Air Handler and Cooling System Project

Recently the chiller in the Aline Wilmot Skaggs Biology building was replaced with a new evaporative cooling unit by Facility Operations due to chronic temperature control problems.  The new equipment has software control that allows for full maximization of the system. A change to the sequence of operations better utilizes the wet bulb temperatures to keep the building cool without the use of chillers. Chillers, like more familiar household air-conditioning units, are used in large buildings to cool the water used in industrial air-conditioning practices.

Evaporative technology is older but with the use of advanced technology through the control software, the unit is able to cool more efficiently. When temperatures reached 100 degrees Monday, June 10^th the unit was able to maintain 55 degree air discharge temperature through the use of evaporative cooling which cooled the building to 72 degrees inside.

Evaporative cooling is used in both new and older buildings where applicable. For example, the new business building has an evaporative and indirect cooling system alongside chillers.  The savings in emissions and energy use are substantial when able to use evaporative and indirect cooling systems.

Those consulted on this project were Building Automations, HVAC, Facility Operations, Energy Management, Sustainability, and Russ Weaver at Atkinson Electronics. This is the type of teamwork, dedication, and innovation that contributes to the continued success of the University of Utah.
