High-performance liquid cooling allows datacenter operation with coolant temperatures above the free cooling limit in all climates, eliminating the need for chillers and allowing the thermal energy to be re-used in cold climates. We have demonstrated removal of 85% of the heat load from high performance compute nodes at a temperature of 60ºC and compare their energy and emission balance with a classical air cooled datacenter, a datacenter with free cooling in a cold climate zone, and a datacenter with chiller mediated energy re-use. We show that our concept reduces the energy consumption by almost a factor of two compared to a current datacenter and reduces the carbon footprint by an even larger factor. Our energy re-use concept can be demonstrated most effectively in terms of cost and energy savings in a homogeneous high performance computing environment.
