Most-advancedDC

●Most-advanced DCThe DC uses state-of-the-art technologies to adapt to the varyingneeds of project owners, tenants, and society, thus retaining its most-advanced state throughout the service life. 1) Develop a most-advanced and next-generation DC

in compliance with required standards. 2) Ensure flexibility to accommodate higher load demand,

changes of tenant needs, etc. 3) Provide high reliability considering environmental conside-

rations with complete safety and security.

The DC responds to IT technologies evolving at an accelerating rateand flexibly deals with various users’ needs, thereby ensuring high profit-ability to client. 1) Reduction of initial cost supported by reliable technolo-

gies and simulations. 2) Reduce running cost through high-level simulation technolo-

gies (6Sigma). 3) Ensure BC (Business Continuity) by enhancing safety and

security against earthquakes (seismic isolation, dampingof longitudinal waves), security, abnormal weather, andothers.

The DC supports higher load density, introduces the most advanced energy-saving technologies, and controls the center in the operational phase, in order to function as green DC. 1) Achieve PUE ≦ 1.5 through the introduction of the latest

technologies including Shimizu Aisle Separate System (patent pending).

2) Establish a green DC by adopting cutting-edge technolo-gies such as free cooling, outdoor air cooling, large tempe-rature gap-using air conditioning, and direct current powersupply system.

Proposal for Environmentally-Sustainable“Green Data Center”

The latest energy conservation technologies are used to control the system in the operational phase to increase efficiency, thereby achieving the minimum PUE (Power Usage Effectiveness)

The system forms cold and hot aislesto increase the air temperature diffe-rence ⊿t to 12℃(18 → 30℃) from the standard 6℃ (18 → 24℃), considerably reducing power.

The direct current power supply system is adopted to simplify theDC-AC conversion process, genera-ting less energy loss from conversion.

Substantial increase in partial loadingefficiency by the use of inverter turbochillerEnhanced efficiency of heat sourceequipment by increasing the cold water temperature to about 15℃.

Air conditioners are controlled to operate optimally, according to the operational states tracked byservers.

After the summer season, the cool- ing system directly uses outdoor air, reducing heat source power.

The system feeds the upstream coil of an air conditioner with cold water pro-duced by a cooling tower (free cooling), the temperature is set at 23℃ or lower to enable long-hour free cooling.
