Asetek's Warm-Water Liquid Cooling System Yields Energy Cost Savings at NREL

Asetek's RackCDU liquid cooling system was installed and tested at the Energy Systems Integration Facility's (ESIF's) ultra-energy-efficient high-performance computing (HPC) data center. The company's direct-to-chip "hot water" liquid cooling system was used to retrofit an existing air-cooled HPC cluster.

High-performance computers generate a lot of heat when in operation. Instead of cooling with air and a number of fans, the RackCDU system uses liquid—which has approximately 1,000 times the cooling capacity of air. The result of the liquid cooling process is reduced cooling energy and hot water, which can be reused to heat the ESIF in the winter. The facility's state-of-the-art HPC data center is designed to be the most energy-efficient data center in the world, making it the perfect place to demonstrate Asetek's energy-saving liquid-cooling technology. The goal of Asetek's cooling approach is to reduce the total energy costs in data centers by improving the efficiency of its computer racks.
