Stakes and technologies for the cooling of Data Centres, Restitution of results of the study undertaken by the Ancre GP8

Whereas data centres are an important issue in terms of energy consumption and water consumption for their cooling, this study first outlines that their energy efficiency is therefore a huge stake from and economic and energy point of view, that their development has however a brilliant future, and that their cooling is a crucial issue. Then, five fields of innovation are considered to properly address the issue of cooling and valorisation of the dissipated heat: the electric power network and its associated equipment, computing components of data centres and supported components, urbanisation and exploitation of the computer room, and technologies of valorisation of the dissipated heat. The report proposes an overview of leaders of the sector and notices the impossibility to choose a technological way to the detriment of an other. Some examples of R and D works and actors in the field of liquid cooling are evoked. A two-level R and D road-map is proposed to address the issue of data centre cooling. A Power point version of the study is proposed which highlights results.
