USA: Largest Solar Cooling System Worldwide
Submitted by Baerbel Epp on September 1, 2014
It is an ideal location for solar cooling use: Scottsdale, a US city in the Greater Phoenix area in Arizona enjoys an average of 312 days of sunshine every year. Between May and September, temperatures rise above 38 °C and can even reach 46 °C on a hot day. This is where in July 2011, Austrian company S.O.L.I.D has started to plan a solar cooling system for Scottsdale’s Desert Mountain High School (DMHS) of 2,600 students. Three years later, the 3.4 MWth (4,865 m² of collector area) system went into operation and is now supplying heat to a single-effect lithium bromide absorption chiller with a cooling capacity of 1,750 kW.
