Client Requirement

To increase the Digital Realty footprint in Ireland to enable the business to capitalise on the growing demand for IT space from overseas enterprise. To achieve a world class PUE below 1.2 without introducing outdoor air into the IT equipment.

DLR were keen to maximise energy savings by utilising the most advanced cooling technology to fully exploit the free cooling opportunities that the Irish climate presented and to cool the facility without the need for compressor based cooling.
The facility to be designed to comply with the Uptime Institute’s TIERIII resilience classification.

A total facility capacity of 15.4MW IT power provision split over 4 buildings with 2 datahall modules per building.

Each of the eight datahall modules to be rated at 1.92MW with the ability to sub divide each hall into 2 x 960KW modules still maintaining N+1 resilience and TIERIII classification.

Excool Solution

Equipment Selected

The Excool indirect adiabatic and evaporative cooling system was chosen for its innovative indirect and compressor-less alternative to traditional chilled water and direct systems.

Client Benefits

BENEFITS AT A GLANCE

The headline benefit delivered by Excel is the energy cost saving.
The annual energy bill difference for a 1920kW site operating at a PUE of 1.6 and 1.15 is approximately €650,000.

Successful Integrated system testing delivered a peak site PUE of 1.2 on one of the hottest days recorded in Dublin Digital Realty. This aligns with the anticipated final operational PUE of 1.15. Excools efficiency gains at lower cooling loads are expected to offset the losses seen by the UPS resulting in a flat PUE across IT load fluctuations.

A calculated WUE of 0.7 and CUE of 0.0625 are expected to be achieved.
The Excool compressor free system has a significantly lower electrical demand which reduces the infrastructure required to support it and redistributes the power provisioned for the site to the IT. Digital Realty were able to increase their available IT power from 1440kW to 1920kW while decreasing the
generator size by 41% and the transformers by 23%. Associated savings on diesel fuel storage, switchgear etc were also realised.
