Liquid Cooling and Reuse of Waste Heat in Super-Computers (Aquasar)

Aquasar is a joint project between the LTNT group at ETH and the IBM research lab in Zurich. In traditional air-cooling a huge amount of energy is consumed to cool super-computers. Switching to liquid-cooling has two advantages:

These features result in a more efficient energy use which reduces the carbon footprint of super-computers.

The Aquasar-system will be installed at ETH Zurich to provide a first working example for the reuse of heat in liquid-cooled super-computers. The waste heat will be used in the heating system of the ETH. This project involves computational and experimental analysis of important parameters in order to optimize the system.
