CIAT carries out the entire air handling installation for the new Uzbekistan national library building

The Uzbekistan national library is the country's biggest library. It houses more than 3.5 million printed works, including 200,000 copies of documents that date from the fifteenth to the nineteenth centuries. 500,000 people use the library every year. Inaugurated in 2011, a new building covering an area of 38,000 sq. m comprising reading rooms, storage rooms, a conference centre with seating for 960 people, and a book museum, was added. The book storage areas are kept at a constant temperature of 18°C.

The building was equipped with:

• 18 Airtech air treatment units,
• 28 Expair precision air handling cabinets,
• 50 Magma ventilation and air extraction units,
• 205 Major Line comfort units,
• 4 Powerciat LXH chilled water production units (cooling-only version with HPS(High Power System) hydraulic system),
• 3 ITEX gasketed plate heat exchangers, and 2 domestic hot water tanks.

One of the main difficulties was to supply chillers that could be installed on the roof, and assembled and dismantled on site.
