We perform maintenance and management of electrical and cooling facilities to ensure stable operation of the K computer. 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.
