Huawei, International Industry Organizations Jointly Launch White Paper on Large Temperature Difference Cooling Systems

[Barcelona, Spain, March 3, 2026] At MWC Barcelona 2026, Huawei officially launched innovative Large Temperature Difference Cooling System and co-published the White Paper on Large Temperature Difference Cooling Systems with the International Industry Organizations. This solution reimagines cooling architecture to help global customers build green, low-carbon data centers, achieving an optimal balance between energy efficiency and cost.

As global data center scale and energy consumption surge, PUE (Power Usage Effectiveness) requirements have become increasingly stringent. With traditional water-cooling reaching its physical limits, the industry is transitioning toward high-efficiency solutions to meet mandates such as PUE ≤ 1.25 for new projects.

White Paper on Large Temperature Difference Cooling Systems Officially Released

Against this backdrop, Guo Dazheng (President of R&D, Huawei Global Technical Service), Chen Haijun (Green IDT owner of Huawei Standards Industry Development Dept), and Xi Xingjian (General Manager of Huawei Data Center Facility Industry Domain) joined Massamba Thiove (Principal Consultant, UGIH) and Paolo Gemma (Chair of ITU-T SG5 WP2/5) to unveil the new White Paper.

Massamba Thiove, Principal Consultant

Massamba Thiove, Principal Consultant, cited the white paper which propose an energy-saving path: improving the performance of cooling systems is critical for data centers as almost 100% of the power consumed by data center is transformed into heat, which is the shadow of computing. Innovative cooling solutions are needed for the further development of AI. The cooling system is structurally central to data centers—not auxiliary. Without effective cooling, computation simply cannot happen reliably. Its importance spans thermodynamics, reliability, energy economics, and climate impact.

Xi Xingjian, General Manager of Huawei Data Center Facility Industry Domain

Xi Xingjian noted that the solution optimizes heat exchange networks to improve cooling efficiency by over 30%, delivering several core benefits:

• Architectural Breakthrough: Maximizes free cooling potential by expanding system temperature differences.

• Energy Efficiency: Drives continuous PUE improvements through advanced simulation and synergistic optimization.

• Reliable Operation: Ensures constant terminal temperatures and equipment safety while maximizing cooling efficiency.

Looking ahead, Huawei remains committed to customer-centric innovation, providing a reliable and intelligent foundation for global data centers to drive a more efficient and sustainable future.
