Huawei’s Dongguan Cloud Data Center T1 project (T1 project for short) is among the two green data centers in China to have been selected as a typical application case of key energy-saving technologies 2021 by the National Energy Conservation Center for the large amounts of energy it has saved during operation. Put into operation in 2019, the project’s PUE reached 1.28 in 2021.

Today, we look at how digital technology enablement contributed to the success of the T1 project.

Due to insufficient simulation of air ducts and airflows at the design phase and backward onsite assembly and construction, traditional data centers have a higher PUE than the designed one. By contrast, the T1 project uses digital design, simulation, and manufacturing, reaching a designed PUE in actual operation.

Digital design
Thanks to the building information model (BIM) and the 3D digital twin technology, the pipeline collision experiments can be carried out automatically and pipeline interference can be identified in advance, improving design quality and reducing changes by 80%.
Digital simulation
Big data, cloud, AI algorithms are used to analyze multi-device working condition curves and full climate databases. On top of that, we use expertise to develop a 3D linkage simulation algorithm involving pressure, temperature field, and airflow, which improves the PUE design accuracy by 20%.
Digital manufacturing
Videos are issued through software to guide production, which ensures consistency between design and production. Besides, digital testing methods are used to keep the air leakage rate of air ducts under 1%, outperforming the industry average of 3%.

Next week, we will look at other advanced energy-savings technology which was employed in the T1 project.
