The TeliaSonera Green room Concept for high and mid density ICT equipment

This paper and presentation aims at present an new concept for construction and cooling of mid and high density equipment (>;10 kW/rack), often located in designated areas in Data Centers. Several of the highlighted solutions has not been invented by TeliaSonera however the concept to combine several of the different solutions in one location and then perform actual verification tests and energy/cooling optimization has not to our knowledge been performed before and that\´s why we have choosen to call this approach "The TeliaSonera Green room Concept". The concept includes al infrastructure at a site such as power, back up and cooling but in this paper we only focus on the cooling part.
