District Cooling is the latest environmental-friendly alternative to traditional chillers installed in individual buildings.
Malakoff Utilities Sdn. Bhd. also provides chilled water for the air-conditioning at Plaza Sentral, and other KL Sentral’s office complexes through its Centralized Chilled Water Plant. The plant capacity can hold up to 7000 Refrigerant Tonnes (RT), equivalent to supplying four blocks of office buildings.
District Cooling is the latest environmental-friendly alternative to traditional chillers installed in individual buildings. District energy systems produce chilled water at a central plant and distributes energy through underground pipes to buildings connected to this system.
Customers can then use this chilled water to meet their air-conditioning needs. Individual buildings no longer need large spaces to host chillers or cooling towers. Once this system is installed, the water is returned to the central plant to be rechilled and then re-circulated through the closed-loop piping system.
With District Cooling, an uninterrupted supply of cold water is available with minimum environmental impact i.e. significant reduction of energy consumption as well as of CFC and CO2 emissions.
The Benefits of District Cooling
District Cooling can reduce electricity usage by more than 65% compared to traditional air conditioning systems. As a comparison, traditional chiller plants account for up to 70% of the electricity usage in a large building.
Individual power consumption is reduced substantially by a shift of load from each building to a central plant. Operational and maintenance costs for spare parts are also greatly reduced.
District Cooling also has advantages in terms of space and comfort. When the individual chiller units and their related equipment are rendered obsolete, the users of the building will no longer be disturbed by intermittent noises or mechanical vibrations which traditional chillers generate.
The removal of the traditional chiller units will also give the building better appearance or aesthetics. District Cooling also provides a better indoor climate through a lower indoor humidity which is obtained by a better chilled water temperature control.
