Mitsubishi Heavy Industries, Ltd. (MHI) has demonstrated a measurable enchancment in Power Usage Effectiveness (PUE) on the Fujitsu AKASHI Data Center, attaining a discount in cooling power consumption whereas sustaining steady operations. This initiative was carried out utilizing multi-vendor infrastructure, adopting a holistic strategy to cooling system management.
Traditionally, information heart cooling optimization has targeted on particular person gear. However, MHI’s mission utilized system-level management throughout all the cooling system, together with shared cooling infrastructure and air dealing with items in server rooms. This strategy has unlocked new power financial savings potential and gives a scalable pathway to boost effectivity in current information facilities.
With the worldwide demand for information facilities surging, power consumption has turn into a big constraint, as cooling programs account for over 60% of non-IT electrical energy use. The rise in AI workloads has additional elevated operational calls for, difficult the effectiveness of current energy-saving strategies, significantly in multi-vendor environments.
A key differentiator of MHI’s mission was its deployment with out service interruption. Utilizing vendor-agnostic cooling system optimization expertise developed by MHI’s Research & Innovation Center, the mission recognized temperature distribution within the server room as a important bottleneck. By rebalancing airflow and managing air con items, the temperature distribution improved by 2°C, offering substantial headroom for optimizing different cooling programs.
Through fine-tuning the operation factors of shared cooling infrastructure and sustaining cooling water at an acceptable temperature, the mission achieved a 2.3% power discount throughout all the cooling system. Additionally, the power effectivity (COP) of the centrifugal chillers elevated by greater than 1.2 factors. When scaled throughout all server rooms, cooling system power financial savings are projected to achieve 7.6%, considerably enhancing general PUE.
“Operational data centers need to improve energy efficiency while utilizing existing equipment,” mentioned Shoji Yamasaki, General Manager of the Data Center & Energy Management Department at MHI. “This demonstration proves that system-level cooling optimization—especially in multi-vendor environments—can deliver tangible results under real operating conditions.”
Looking forward, MHI plans to broaden this strategy, integrating decarbonized power, resilient energy programs, high-efficiency cooling, and superior digital options to assist sustainable and dependable information heart operations worldwide.
