DescriptionAs we move toward exascale computing, energy efficiency and power consumption is proving to be a major challenge for HPC data centers. Any power spent on cooling detracts from IT performance. After pioneering chiller-free, high-temperature, direct-liquid cooling with the SuperMUC HPC system, the Leibniz Supercomputing Centre (LRZ) demonstrates for the first time the feasibility of using adsorption chillers in a Top500 production environment to generate necessary cold water. Since adsorption chillers can produce cold water from the heat energy generated by the HPC system with little additional electrical energy, they are a very effective tool in reducing power and energy consumption. Initial efficiency data at LRZ indicates an electric Coefficient of Performance (COP) of more than 10, which is more than double compared to traditional mechanical chillers.
