In this space, waste heat is extracted from circulating water that also supplies room-temperature water to the data center. One of the innovations that makes Frontier so energy efficient is this “warm-water” cooling system. Credit: ORNL, U.S. Dept. of Energy

oakridgelabnews posted a photo: Waste heat from the Frontier supercomputer is extracted from circulating water through a closed loop system. Large evaporative cooling towers eject the equivalent of up to 20MW of heat, or 6000 tons, from the primary loop to the atmosphere. This waste heat ejection is the final step in the heat removal process for Frontier and other supercomputers using warm-water …
