Demonstration Test of Immersion Cooling System Achieved 94% Cut in Power Consumption

KDDI Corporation, MHI and NEC Networks & System Integration Corporation conducted a demonstration in which 100kVA class servers and other IT equipment along with an immersion cooling system were housed in a data center for a test run.

We developed an immersion cooling system including a free cooling unit that performs optimized air cooling and achieved a 94% cut in energy consumed to cool the servers, with a PUE of 1.05. In addition, high availability was obtained in the immersion cooling and free cooling units, confirming stable operation and viability of use of such equipment to achieve a Tier 4 level (highest quality for data centers) immersion cooling data center.

Test Operation of Container-type Data Center Proven Power Savings

In 2021, KDDI Corporation, Mitsubishi Heavy Industries (MHI), and NEC Nets-SI, Ltd jointly conducted validation testing for operating an immersion cooling system housed in a 12-foot shipping container with a 50kVA class server and other IT equipment. This proved the reduced power consumption by 43% compared to conventional data center models and achieved a PUE of 1.07 in a compact container-type data center.

Container-type data centers offer the key advantage of shorter lead time for construction. Their ease of installation can also significantly make it applicable to wider installation environments and conditions for data centers, enabling flexible construction in a variety of places.
