Data Centre Cooling
On average, existing computer rooms and data centres have around twice as much
cooling as they require but many of them are facing problems due to hot spots.
Blade servers and networking equipment now mean that the capacity that used to fill
a room can now be contained in a single rack which creates extreme power and heat
problems.
Power densities are increasing with many server racks already exceeding 10kW and
future predictions of 20kW, 30kW and beyond mean that the traditional hot aisle/cold
aisle approach simply can not cope.
More cooling plant requires more electrical power to drive it, yet supply companies can
not always guarantee it and the concern over Carbon-Footprint is focusing companies on
reducing their power use.
