La plus grosse installation solaire à adsorption du monde

La société autrichienne SOLID a mis en place cette installation de froid solaire à Scottsdale, en Arizona, qui bénéficie de 312 jours d'ensoleillement par an.
The Valley of the Sun is one of the hottest areas in the United States with summer temperatures climbing to 40°C or above. Austrian company SOLID has installed a solar cooling for Desert Mountain High School, in Scottsdale, Arizona, a city in the Greater Phoenix area which enjoys 312 days of sun annually.

The project, initially launched in the summer of 2011, now keeps 2,600 students cool thanks to a 4,865 m² collector area and a 1,750 kW capacity cooling system, making it the most powerful solar-cooling plant of its kind. A lithium-bromide adsorption chiller operates on full load during the hottest hours of the day. In the summer, it covers 100% of the cooling demand and back-up electric chillers step in when required.

The total cost of the installation amounts to around 10mn USD (8.5mn euro) and was partly financed thanks to Solid Invest, a new fundraising model by which private investors can lend money and receive a fixed interest of 4% and mostly also by the Raiffeisen US Finance Bank.
