Research Summary

Shinichi Miura

Supercomputer constantly consumes large amounts of electricity and the power changes into heat. Providing a stable supply of the consumed power and reliably eliminating the waste heat will draw out the full potential of the supercomputer.
Facility Operations and Development Unit performs maintenance and management of electrical and cooling facilities to ensure stable operation of our supercomputer. We are also working on R&D for maintaining an optimal working environment by combining steam-driven absorption refrigeration and inverter turbo refrigeration equipment, together with the operation of two 5000kW-class cogeneration systems.
