The District Cooling System at the Kai Tak Development
The HKSAR Government is taking the lead to implement a first-of-its-kind district cooling system(DCS)in Hong Kong at the Kai Tak development(KTD).KTD is a huge development project spanning a total area of over 320 hectares that covers the ex-airport and nearby areas.The planned total public and private non-domestic airconditioned floor area in KTD amounts to about 1.73 million square metres which will require a large demand for air-conditioning of about 284 megawatt of refrigeration(MWr).The DCS project is to construct a large scale centralized air-conditioning system.Chilled water is produced at the central chiller plant rooms and distributed to the consumer buildings in KTD through an underground chilled water pipe network.The project is implemented in three phases.The first two phases were completed and the final phase of the project is expected to be completed by 2022.The DCS at KTD has been put in operation since Feb 2013 to provide cooling services to the Kai Tak Cruise Terminal building.DCS is the most energy efficient centralized air-conditioning system,consuming about 35%less electricity as compared to traditional air-cooled air-conditioning system,and is suitable for promoting building energy efficiency in new development areas.Upon completion of the project,the DCS at KTD is expected to achieve an annual saving of about 85 million kilowatt-hour in electricity consumption.Apart from energy saving,DCS will also help to mitigate the heat island effect in KTD by eliminating the heat rejection of separate air-conditioning system from individual buildings.Other benefits for individual consumers include reduction in upfront capital cost,more flexible building design,no noise and vibration arising from the operation of heat rejection equipment & chillers and a more adaptable air-conditioning system to the varying demand.
