An innovative solar-thermal heating and cooling system installed on top of the UA's Student Recreation Center is expected to harvest almost 200 million kilowatt hours of solar energy per year – enough to power more than 180 households.
At the heart of the solar thermal cooling and pool heating system is an array of 346 argon-filled vacuum tube solar thermal collectors installed on the roof of the UA’s Student Recreation Center.
The collectors utilize heat from the sun as a free energy source to drive an absorption chilling system to help keep buildings on campus cool while also heating the recreation center’s main swimming pool.
An absorption chiller works similarly to a refrigerator or an air conditioner, except it uses a process relying on heat, rather than electric power.
