A new district cooling system utilizing ice/water slurry (new DCS) has been proposed and it may take the place of the usual district cooling system utilizing cold water only. In this work, a pilot plant of the new DCS was built using the elemental apparatuses developed so far and, performance tests were made. It is important to take out ice of the tank at a desired rate irrespective of the Ice Packing Fraction (IPF) in the tank, and to keep the ice fraction constant through the pipeline network in the DCS so that high quality and high density cold energy is supplied to the users. After some improvements of the form of the ice storage tank, ice fraction control system and so on, the continuous operation test of the pilot confirmed that the cold energy is supplied steadily to the demand side by the ice/water slurry system.
