The DCS at KTD is a large scale centralized air-conditioning system. It utilizes sea water to produce chilled water at the central plants and distributes the chilled water to consumer buildings in the KTD through underground water piping network.

The DCS at KTD comprises two central chiller plants, namely the North Plant and the South Plant cum seawater pump house, underground chilled water distribution piping network, seawater supply and discharge pipes and consumer substations located in the buildings to interface with the building’s own chilled water circulation systems.

The cooling capacity of the DCS is about 284 megawatt of refrigeration (MWr) for serving the non-domestic air-conditioned floor area of about 1.73 million m², equivalent to a cooling supply for 40 nos. of 30-storey high commercial buildings. Upon completion of the project, about 40 kilometres of underground chilled water pipes would have been laid and there would be around 60 buildings in KTD connected to the DCS.
