Singapore’s largest industrial district cooling system which was designed and built by a joint venture between SP Group and Daikin Airconditioning (Singapore), has commenced operations.
The system has an installed capacity of up to 36,000 refrigeration tonnes (RT) and delivers continuous chilled water via a centralised closed-loop pipe network replacing individual chillers in each building.
The total area served by the system is approximately 90,000 square metres.
Chillers in a series counterflow configuration reduce the energy required to cool the water.
The system is expected to reduce carbon emissions by up to 120,000 tonnes per year and enable 20 per cent savings on cooling-related electricity consumption. It will also repurpose over half a million cubic meters of water each year by using reject reverse osmosis water.
Incorporating whole-life carbon assessments during design and construction of the plant also enabled a reduction of about 44 per cent in embodied carbon compared to industrial building benchmarks.
