Working in partnership with contractor Sudlows, Airedale provided cooling plant with a projected PUE level of 1.14 (load dependent).
Equipment included two 500kW Airedale DeltaChill FreeCool chillers, two 34kW SmartCool chilled water precision air conditioning units and 35 high density OnRak rear door IT cooling units with up to 25kW load per rack. In addition the Leeds-based manufacturer supplied an external generator, building fresh air supply, battery and build room air conditioning units; UPS room equipment; and water leak detection and fire suppression systems.
The system is controlled by Airedale’s ACIS web-based control interface. As well as monitoring all elements of the site, ACIS also integrates with the University’s legacy building management system allowing full visibility of data centre alarms from the main site.
The Airedale solution provides indirect free cooling to the data centre, with direct fresh air free cooling the UPS room, delivering free cooling up to 95% of the year depending on ambient temperature. When free cooling is available, chilled water set points are maximised up to 20°C to prolong free cooling.
