Evaporative Cooling Data Centre Case Studies
Cooling the Server Room
The Server room at Keele University used to be cooled using two wall mounted air conditioning units, however, the load in the area needed to be increased and additional cooling was required. Therefore in line with their energy management strategy rather than installing another refrigeration based air conditioning unit the Estates Department wanted to fit something more environmentally friendly and EcoCooling were approached to provide a solution.
One down discharge EcoCooler was installed on top of the existing roof light. It contains two non-return shutters on either side to allow the warm air to be extracted from the area. The unit introduces cool filtered air down the centre of the area, this air is then extracted through the shutters once it has warmed up.
A patented attemperation system maintains a constant temperature supply to the IT equipment. The hot air is mixed with ambient or evaporatively cooled air, using a single damper.
When the external temperature rises over a set point the evaporative cooling is enabled to ensure either the typical target air supply temperature of 21°C is achieved or slightly over during the very hottest periods. A standard EcoCooler CREC module will supply 3 cubic meters per second which can support over 35kW of IT load. Keele are expecting to save 90% on their energy bills compared to an equivalent air-conditioning system.
