District cooling is distributed to consumers by an under-ground closed loop pipe systems consisting of supply and return pipes running in parallel. The pipes diameters range from 75mm to 1,400 mm.
The most common technology for distribution systems is to use pre-insulated steel pipes, but also other alternatives such as polyethylene pipes are in use. Energy losses from district cooling pipe systems are rather low due to similar ground temperatures.
The total area served is 3.9 million square meters (41 million square feet) at the Pearl Qatar District. The length of the pipe distribution network is 92 kilometers (57 miles). This consists of both the supply and return pre-insulated steel pipes. The Pearl network also boasts on boosting station on the island.
Qatar Cool serves over 1.9 million square meters (20 million square feet) in the West Bay District. The length of the pipe distribution network is 28 kilometers (17 miles). This consists of both the supply and return pipelines with pre-insulated steel.
