More comfortable lecture halls with evaporative cooling

In 2006 a decision was made by royal decree to build the university for female students only in Saudi Arabia. The first stone was personally laid by King Abdullah.
This is a major development. The university complex will be able to host up to 40,000 students, twice the number of students enrolled at Oxford. The students will be able to choose between 15 faculties on a large campus that, among other facilities, includes a 700-bed hospital, staff accommodation, a school, a kindergarten and a high-tech transport system. The decision by the King to take part in the ceremony to inaugurate the work is seen as a sign of his personal commitment to promoting education in Saudi Arabia, both for women and men.
Zamil Air Conditioners, the company charged with supervising this enormous project, was founded in 1974 and was one of the first companies to deal with air-conditioning in Saudi Arabia. Its headquarters are in Dammam and today it is an international-level manufacturer of air-conditioning systems, as well as the leading company in the sector in the Middle East, thanks to strategic alliances and significant investments in research and development. The Zamil group also includes the Italian company "Geoclima srl", manufacturer of chillers and fan coils, acquired in 2000, and the Austrian company "Clima Tech Airconditioners GmbH", acquired in 1998, which develops and manufacturers air handling units.
The ChillBooster evaporative cooler has been chosen for the air handling units. This unit, compared to adiabatic washers typically used in these applications, guarantees a higher absorption ratio and less hygiene problems. The latter in fact occur when recirculating a large amount of water, a resource that moreover has limited availability.
The various university environments are now air-conditioned by double skin air handling units, each fitted with a ChillBooster evaporative cooler. Direct evaporative cooling, especially suitable for hot and dry climates, reduces temperatures in summer by around 10 °C, with very low energy consumption.
