A District Cooling System using Ice Slurry for the Uncertain Cooling Load of the Future and its Economic Evaluation

Yoon-Pyo Lee, Ahn Young-Hwan, Yoon Seok-Mann

Abstract

A new district cooling system using ice slurry for the uncertain cooling load of the future is presented. The chilled water produced by the absorption chillers is used for the base cooling load. The temperature of the chilled water is reduced by mixing of ice slurry depending on increasing of the cooling load. Finally, IF of the ice slurry is increased up to 10% at the peak load. The transporting mass flow rate is decreased down to 44.7%, and the diameter of the main pipe is decreased down to 66.7%, but the diameter of the branched pipe is designed as the same size of the chilled water.
