“We recognise that reducing our impact on the environment will take time, but it’s a journey we’ve been accelerating,” says Jon Hampson, Head of the Environment Program.
Capgemini have installed a system of 5 EcoCooling evaporative coolers and 4 ducted extraction fans to replace an old system of five air conditioning units. The old air conditioning units were cooling the basement Data Centre at their offices in Birmingham.
The extraction fans are used to remove excess heat from the building, while the EcoCoolers draw in air from outside which flows over damp evaporative cooling pads to enable the natural cooling effect.
The EcoCooling CRECS (computer room evaporative cooler system) provide over 140kW of cooling into the basement area, ducting the air through a raised floor.
The new system is expected to save over £36,000.00 of electricity per annum and over 270 tonnes of carbon emissions, compared to the old inefficient air conditioning system.
The environmentally friendly EcoCooling system, is a fresh air based system which uses no refrigerants it has a patented ‘attemperation’ system (mixing of hot and cold air to a fixed set point) to ensure that the area is fed with correct temperature air throughout the year, even in the depths of winter using waste heat from the Data centre to temper the incoming fresh air.
The system also incorporates 5 smoke vents which would be used in the event of a fire within the basement.
By ulitising the Evaporative cooling systems, Capgemini is able to save up to 90% of their cooling costs when compared to traditional refrigeration, as well as significantly reducing their carbon footprint.
