Data Centers

We propose optimal energy-saving solutions for data centers that are in line with your needs.

Ref Assist*, a local cooling system for data centers that utilizes the natural circulation of refrigerants

The Ref Assist air conditioning system achieves significant energy savings, increased server installation space, and minimizes underfloor space compared to conventional floor air-emitting air conditioning.

Combining the natural refrigerant eco-system with high efficiency heat sources and free cooling leading to significant reductions in air conditioning power consumption. Air conditioning power consumption 60% *1 DOWN

*1: Comparison with conventional package type air conditioner with air outlet on floor at the time of 2004 (according to our calculations) (with a server room area of 51.5 m2, 25 racks, and a load of 5 kW per rack)
*2: Comparison of air conditioners for computing (floor type) and Ref Assist (ceiling suspended) (according to our calculations) (server room area 3,040 m2, 1,200 racks, load 5 kW per rack)
*3: When the free access floor of the 5th floor building is changed from 800 mm to 300 mm (based on our calculations)

24/7 all-year-round support for data centers by optimizing electricity supply facilities

Rooftop installation of substation equipment and UPS on each floor, as well as improved reliability of power supply through the use of double substation and power distoribution.

Enewatcher*, a tool that visualizes energy consumption

Uses a variety of energy consumption graphs, making it easy to grasp energy consumption trends and manage energy efficiency such as PUE.

Numerous browser-based graphs and analysis functionality are available
Power demand monitoring functionality that uses email notification is available
Easy management of operating efficiency elements, such as energy consumption rate and PUE & COP
Scale up to a more advanced management system by incorporating energy-saving control logic

(PUE = Power Usage Effectiveness)
