Each Johnson Controls’ York centrifugal chiller unit is 26 feet long, 11 feet wide, and 14 feet tall, and weighs 2,500 tons. The units will be shipped from San Antonio to Qatar, and installed in the world’s largest district cooling chiller plant. The facility will supply 130,000 tons of chilled water daily to cool more than 15,000 residential and commercial units, providing comfort to the 40,000 Pearl-Qatar residents. The man-made island covers 985 acres of reclaimed land offshore the Arabian Peninsula state of Qatar, the Arab world’s wealthiest per capita country.
“It is such an honor to have been selected to design and manufacture products that will contribute to this incredibly unique property,” said Ray Ring, regional manager, Johnson Controls. “The plant into which these units will be installed will not be duplicated and is certain to become a global landmark. Our ability to meet the difficult demands of this site demonstrates the technical innovation and expertise we bring to every job.”
Ring said a number of factors led to selection of Johnson Controls for the project:
• Environmental sensitivity. Qatar recently enacted a law to control, reduce, and phase out its import of ozone depleting substances. The chillers are energy efficient and use environmentally friendly and non-ozone-depleting HFC-134a refrigerant.
• Product durability under harsh conditions. The chillers will operate at extreme conditions, where entering condenser water temperatures can reach up to 97°F at 122°F ambient. Many other chillers can shut down under such extreme operating conditions.
• Reduced operating costs. This chiller requires half of the electrical switch gear normally needed in a plant of this type. Johnson Controls also is installing its Metasys® building automation system to ensure the cooling plant operates at maximum efficiency.
The chilled water will be distributed through an underground network of 10-foot tall pipes laid out across the island. Delivery and installation of the chiller units is expected to begin in December 2007 and continue through May 2008.
