Complex wall for indirect freecooling in datacentres

Thermal management of data centers becomes a major issue as the power dissipated by the telecommunication equipments, has dramatically increased, leading to hot spots and to huge overall energy consumption. This paper concerns a new architecture for data centre. Data centres were often built in a classical way without any optimization. Due to growing energy consumption, studies must been done in order to optimize energy devoted to cooling. This study shows an original approach to reduce energy consumption of air cooling in telecom buildings. With large climatic ranges it is now possible to use free cooling with some issues like filtration. The architecture proposed here is a complex and tight wall with a heat conductive layer.
