Carrier’s AquaEdge Chiller Plant Solution Reduces Energy Consumption for OneAsia Nantong Data Center

NANTONG, China -

Optimization can reduce the annual electricity bill by approximately RMB $1.27 million

Carrier continues to provide lifecycle solutions for complete data center optimization that exceed the standards set by the Ministry of Industry and Information Technology and the National Energy Administration of China. With OneAsia’s data center located in Nantong Industrial Park, Carrier collaborated with the company to build its first China data center equipped with a water-cooled chiller system. By optimizing the energy efficiency of the entire cooling system, the high-efficiency chiller plant can reduce the annual electricity bill by approximately RMB $1.27 million. Carrier China is a part of Carrier Global Corporation (NYSE: CARR), the leading global provider of healthy, safe, sustainable and intelligent building and cold chain solutions.

The OneAsia data center is 120,000 square meters 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 AquaEdge® 19XRV 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 center 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. In order 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%. 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. The annual operating energy consumption is estimated to be reduced from 9,640,006 kWh to 7,846,985 kWh. Calculated at RMB0.71 per kWh, the annual electricity bill can be reduced by about RMB $1.27 million. 

“At the same time as China’s carbon peak and carbon neutrality pledge to build a more sustainable society, data centers have never been more strategic or critical than they are today,” said Cissy Wang, Managing Director, Applied Equipment, North Asia, Carrier HVAC. “Carrier is here with purpose-built solutions and expertise to help face data center challenges with confidence. We look forward to working with our clients to create more new benchmarks for data centers like we did with AsiaOne.”
