Carrier has collaborated with cloud-based services provider OneAsia to build the company’s first data centre in China equipped with a water-cooled chiller system.
The data centre in Nantong Industrial Park, China, is 120,000 square metres and includes 846 cabinets with a total load of 10,548 kW.
Carrier’s solution to reduce power usage effectiveness (PUE) includes the design of a high-efficiency chiller plant with four Carrier AquaEdge19XRV centrifugal chillers, a computer room group control system and power distribution system.
The solution also includes Carrier Comfort Network (CCN) controls.
OneAsia is the first data centre project based on a programmable logic controller (PLC) framework for CCN in China.
In addition to participating in the PUE planning, Carrier also provided the data for the annual dynamic load and energy consumption analysis, as well as group control strategy support.
Carrier optimized the design of the entire cooling system of the chiller plant to meet China’s GB50174 A-level standard.
To enhance the overall energy efficiency of the chiller plant, Carrier provided the AquaEdge 19XRV chillers with variable frequency drive (VFD) conversion technology to increase the partial load by up to 74.4 per cent. The result is improved efficiency and reliability under low ambient temperature.
By optimizing the pipelines in the equipment room, improving equipment energy efficiency, and deploying energy-saving designs for the group control system, the annual average operational energy efficiency ratio (EER) of chiller plant system increased from 7.05 to 8.67.
