Leicester City Council wished to deliver direct fresh air cooling with a closed loop backup to mitigate any local air quality issues. Energy efficiency was central to the data centre requirements. Not only was an annualised PUE3 of sub 1.1 demanded, but also the implementation of renewable energy technology and the utilisation of waste heat.
Workspace Technology is an established industry leader in data centre direct fresh air cooling deployments. Freecool® was the technology of choice and the only technology on the market that could fulfil the PUE design requirements of the Council.
Freecool® Evaporative Free Air Cooling by Workspace Technology delivers innovative low energy cooling for a range of applications including data centre environments. The implementation of the ‘Cool Wall’ module delivers mechanical backup or top up cooling for all modes of system operation.
Freecool® installations are designed and built from scalable standardised modules that can be interconnected in a bespoke arrangement supporting ‘real world’ client applications. The Leicester City Council project was no exception with the solution designed to support a maximum critical load of 250kW N+1 with a deployment of nine 30kW Freecool® units.
As part of the deployment, Workspace Technology implemented the Cool Wall module which consists of a series of high efficiency chilled water coils, positioned within the Freecool® Mixing Box, combined with an external mechanical cooler and buffer tank. The Cool Wall module is designed to deliver the Council’s data centre with an independent back up cooling circuit. Cool Wall activation is based on a range of configurable environmental conditions including fire, air quality, temperature and humidity.
Renewable Technology Delivers True Carbon Neutral Cooling
Photovoltaic (PV) technology delivering up to 35kW of power was installed as part of the project. The PV based kWh power contribution exceeds that of the Freecool® kWh power consumption. As a direct result, the Council’s data centre facility can truly describe its cooling as carbon neutral.
This is one of the first of its kind in the UK and it is hoped that this model will act as the template for future data centre deployments.
This is a tremendous achievement from Workspace Technology’s Data Centre Solutions in-house Design Team. Based on predicted “free” green energy that will be produced by the PV technology, we are fully confident that on average this will neutralise the power demands of our industry leading Freecool® systems. Workspace Technology will be tracking the performance of this installation closely through our EcoMeasure energy monitoring systems and will be publishing data over the next 6 to 12 months.
