This unique project consists of a series of evacuated solar tubes to capture heat and solar radiation. As water cycles through the system, it is heated by the captured energy, which is then run through an absorption chiller. This allows the system to contribute to the cooling capacity of the University of Arizona campus, thus reducing the overall energy requirement. As a byproduct, residual heat unused by the chiller can be piped through a plate and frame heat exchanger to supplement heating the Student Recreation Center Pool.
"We are not aware of any other campus in the country that has used solar thermal energy in this way, which makes this project truly unique," said Kathryn "Kitty" Maloney-Langmade, president of W.J. Maloney Plumbing. "We are proud to be involved with APS Energy Services and Greenfield Dynamics. It is exciting to be on the cutting edge of this technology."
