Asetek <a href=\"http:\/\/www.asetek.com\/press-room\/news\/477-asetek-to-install-liquid-cooling-at-worlds-most-energy-efficient-data-center.html\">announced<\/a> that NREL will install its RackCDU (Rack Coolant Distribution Unit)\u00a0direct-to-chip liquid cooling system, as the cluster is relocated to the new data center at the Energy Systems Integration Facility (ESIF) in Golden, Colorado.<\/p>\n<p>Last year, NREL had been studying the\u00a0energy efficiency performance, savings, lifecycle cost, and environmental benefits of RackCDU for potential\u00a0broader adoption across the DoD. At the ESIF data center, warm water (75 degrees) liquid cooling will be used to\u00a0operate servers and to recover waste-heat for use as the primary heat source for the building office space and laboratories.\u00a0The higher liquid temperatures used by Asetek\u2019s RackCDU (105F) will improve waste-heat recovery and reduce water consumption for the data center.<\/p>\n<p>By retrofitting an existing air-cooled HPC cluster with RackCDU, NREL will reduce the cooling energy required to operate this system, reduce water usage in the cooling system and increase the server density within the cluster, reducing floor-space and rack infrastructure requirements.\u00a0The system will be installed as a drop-in retrofit to existing air-cooled servers and racks.<\/p>\n<p>\u201cAmbient water temperature in the hydronic system is a critical factor in data center efficiency and sustainability,\u201d said Steve Hammond, director of the Computational Science Center at NREL.\u00a0 \u201cStarting with warmer water on the inlet side can create an opportunity for enhanced waste-heat recovery and reduced water consumption, and in many locations can be accomplished without the need for active chilling or evaporative cooling, which could lead to dramatically reduced cooling costs.\u201d<\/p>\n<p>The new Energy Systems Integration Facility is located at the\u00a0 NREL&#8217;s\u00a0campus in Golden. The data center is set to complete construction this summer.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Photo shows a server tray using Asetek&#8217;s Rack CDU Liquid Cooling system.
