Thermosyphon Cooler Hybrid System for Water Savings in an Energy-Efficient HPC Data Center


In August 2016, the National Renewable Energy Laboratory (NREL) installed a thermosyphon hybrid cooling system to reduce water usage in its already extremely energy-efficient High- Performance Computing (HPC) Data Center. In its first year of use, the system saved 4,400 m3 (1.16 million gal) of water, and 7,950 m3 (2.10 million gal) during a 2-year period, cutting the use of water in the data center by about one-half.

The links below detail the project outcomes through several documents, including a Fact Sheet, Powerpoint, and an installation and final report.
