Johnson Controls’ biggest order of YORK water cool chiller units relies on cutting-edge technology

YORK Chillers
Keeping your cool can be a challenge in the heat-baked climes of the Middle East.
But Johnson Controls will make one island in that part of the world a bit more comfortable, thanks to a record-setting order.
Qatar Cool, the district cooling authority for the Pearl Island of Qatar in the Arabian Gulf, signed a contract with Johnson Controls to receive 46 YORK water cool chiller units. The order, which represents the company’s largest single order for chiller units in its history, carried an option to purchase six additional units. That option has now been used and the order is for 52 chillers.
The chillers will be installed in the world’s largest district cooling plant. The facility will supply 130,000 tons of chilled water to air-condition more than 15,000 structures and provide comfort to the 45,000 residents.

Unique Challenges
The project’s importance extends beyond the immensity of its operational scope. One additional element deals with environmental sensitivity. Qatar recently enacted a law to control, reduce and phase out its import of ozone-depleting substances. The YORK chillers meet these parameters with the use of environmentally friendly and non-ozone-depleting HFC-134a refrigerant.
Another factor is the harsh operating conditions of the Arabian Gulf. The Johnson Controls’ YORK chiller will continue to function despite entering condenser water temperatures that reach as high as 97 degrees Fahrenheit. Many other chillers shut down under such extreme operating conditions.
Still another consideration is energy efficiency. The YORK chiller requires half of the electrical switch gear normally needed in a plant of this type. Johnson Controls is also 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 across the 985-acre manmade island.
Each of Johnson Controls YORK centrifugal chiller units is 26 feet long, 11 feet wide and 14 feet tall.
The chiller units will help keep residents of Qatar cool while addressing unique sustainability concerns with advanced technological solutions.
