Improving point 2:

Reduce energy consumption in computer rooms through better architecture

Traditional data centre architecture consists of computer rooms with raised floors on which rows of racks stand, separated by cold aisles and furnished with an array of air-handling units. In the past, when energy consumption and energy costs played a less dominant role, this was a logical and efficient layout.

However, this leads to long circuits and many resistances and consequently to high energy consumption by the air conditioner ventilation fans.

Coolers over the racks (UseCool®)

Everyone knows that cold air sinks. Therefore, it is logical to position the coolers directly over the racks allowing the cold air to descend naturally. This shortens the airflow circuit and reduces air resistance. A watertight barrier between the coolers and the racks prevents water leakage problems. The only power that is now required by the fans is to overcome the reduced resistance of the generously sized coolers. This arrangement minimises energy consumption for the airflow in the computer rooms.
