Great Library of Alexandria (Egypt)

Carrier to Cool the Great Library of Alexandria
CAIRO, EGYPT

Upon entering the new millennium, thousands of rare, antique books will be preserved for future generations with the help of Carrier cooling equipment in the new Bibliotheca Alexandrina, or The Great Library of Alexandria, set to open on the shores of Egypt's oldest Mediterranean city.

Perfectly located on the site where Euclid and Eratosthenes taught geometry and astronomy more than 2,300 years ago, the library will provide scholars with an environment more conducive to learning than that enjoyed by their ancient forbearers, who traveled from all over the region to study in the best stocked library of the age.

Miraco-Carrier, the leader in the Egyptian air-conditioning market, supplied the state-of-the-art air conditioning system, manufactured in North America, to cool The Great Library. The system was installed well in advance of the library's scheduled fall 2001 opening.

The cooling system includes four 19XR Evergreen® centrifugal chillers, using non-ozone depleting, chlorine-free R-134a refrigerant. Each of the 2,110 kW units provides approximately 3,500 tons of cooling. The system also uses sixty 39FX air handling units, twenty-one 42VC fan coil units and thirty-two 35DA variable air volume units. Located in a basement mechanical room of the 13-floor structure, the system is designed to ensure a yearlong uniform temperature within the library, providing comfort for visitors and helping to preserve the library's vast collection.
