University Technology of Petronas (Malaysia)
Project Description
Power and chilled water are supplied to facilities of University Technologies of Petronas. Its unique configuration is available to achieve the high effective operation due to peak cut of both daily peak demand of power and chilled water. The chilled water thermal storage tank is effective for leveling of power generation too.
