In what will be an Australian first, the CSIRO Geothermal Project will deliver a novel solution for cooling the Pawsey Centre supercomputer, an A$80 million facility currently under construction in Kensington, south Perth.
“The system is known as groundwater cooling, and works by pumping cool water from a depth of around 100 metres through an above-ground heat exchanger to cool the supercomputer, then reinjecting the water underground again,” said CSIRO’s project director, Steve Harvey.
“Although the water returned to the aquifer is a few degrees warmer than the surrounds, the groundwater cooling system is engineered to prevent negative impacts to the surrounding environment.”
