ColdLogik solution for ATL1 adds a unique approach. Waste energy that comes out of a server in a cabinet is exchanged by heating naturally cold water that runs through a closed-loop system in each cabinet rear door. The water is heated, and then rejected out of the building as new naturally cold water is cycled back in to replace it keeping the cabinet continuously cool.
That system alone would represent a major innovation in data center cooling But, in our mission to continuously evolve the data center experience, DataBank took the implementation one step further.
In the typical data center environment, any heat removed with CRAC units is usually sent back to the central plant, exchanged for condenser water, and receded off the roof via typical heat rejection. Instead of wasting the heat, the ATL1 facility is actually sending it over to the CODA building’s high-rise boilers and allowing tenants to reuse and repurpose it to heat their offices in colder weather, thus further offsetting energy use.
Using USystem’s ColdLogik rear door coolers, DataBank and Georgia Tech are cooling 50 kW per enclosure, per rack, using 73-degree warm water. And this rear door cooling system can use that same capacity to cool up to 100 kW per rack with just minor changes in infrastructure.
- Cooling 50 kW with 73 degrees, with the potential to double
- 90% less energy consumption
- 80% more real estate than traditional cooling
