The expansion of Dubai International Financial Centre (DIFC) district cooling plant has been achieved by the installation of six centrifugal chillers which used HFO based next-generation, low-global warming potential (GWP) refrigerants. District cooling systems have become an integral part of planning and designing modern buildings in Dubai, with an awareness of the importance of efficient and environmentally responsible cooling systems.
Each new centrifugal chiller has a capacity of 11 MW (3,150RT) increasing the total capacity to 218 MW (62,000 RT) and the plant is now one of the largest operational district cooling plants in the region. The Dubai-based district cooling services provider currently operates more than 4712 MW (1.34 million RT) in 73 district cooling stations, and the number of buildings supplied reached 1,000 by the end of 2017.
Note: Centrifugal chillers are designed to operate for over 25 years, so energy efficiency, refrigerant selection and reliability are critical features.
