It will give jobs to our country men and women.<img src="http://www.tabreed.ae/uploads/imagebank/b82c7a49.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />District Cooling OverviewDistrict cooling is an essential utility for sustainable economic and urban development.In its simplest form, district cooling is the production and  distribution of chilled water from a central source to facilitate air  conditioning.  This is done by producing chilled water at a central  plant and then piping the water to customers through an underground  insulated pipes network.District cooling is suitable for large-scale, high density  developments such as downtown business districts, airports, military  bases, university campuses, residential towers and commercial  establishments.Depending on availability, district cooling plants can utilize a  variety of conventional fuels such as coal, oil or natural gas.  They  can also be converted to use renewable fuels such as biomass,  geothermal, and combined heat and power. District Cooling is a simple process: <ul> <li data-xf-list-type="ul">A central plant chills water </li> <li data-xf-list-type="ul">A primary water circuit then distributes the chilled water to  customers' buildings     through an underground insulated pipes network</li> <li data-xf-list-type="ul">A secondary water circuit in the customers' building circulates the cold water</li> <li data-xf-list-type="ul">Air is then forced past the cold water tubing to produce an A/C environment</li> <li data-xf-list-type="ul">The warmer water of the primary circuit is returned to the central plant to be re-chilled and recycled</li> </ul>District cooling is a superior alternative to  conventional air  conditioning as it helps reduce energy consumption and  costs to both  customers and governments alike, while also protecting  the environment  by cutting carbon dioxide emissions. Some of the  advantages district  cooling has over traditional air conditioning  include:<ul> <li data-xf-list-type="ul">50% less energy consumption </li> <li data-xf-list-type="ul">Decreases initial capital investment and spreads costs over a longer period of time </li> <li data-xf-list-type="ul">Annual maintenance costs are substantially lower</li> <li data-xf-list-type="ul">Can store up to  30% of potential output by holding chilled water in reserve, therefore easily meeting demands in seasonal variations </li> <li data-xf-list-type="ul">Equipment needs to be replaced only every  30 years –  as compared to 15 years for traditional air conditioning </li> <li data-xf-list-type="ul">Greater  reliability due to the high standard, industrial equipment utilized and back-up chillers on stand-by </li> <li data-xf-list-type="ul">Protects the  environment by reducing CO2 emissions due to lower energy consumption</li> <li data-xf-list-type="ul">District cooling systems are remotely located and therefore  enhance real estate value by freeing up space for other uses</li> </ul></blockquote>
