Résumé

In order to deploy the dynamic-type ice storage system in a District Cooling and Heating System (DHC), the effects of ice content (Ice Packing Factor, IPF) and mass flow rate of supplying ice slurry on the ice storage characteristics in a tank were investigated both experimentally and analytically. By raising the IPF and reducing the mass flow rate of supplying ice slurry, the ice-rich layer was hard spread horizontally in the tank. The overall porosity of the ice-rich layer converged to the value of 0.8-0.9 in the ice storing process. The analytical results of the shape of the ice-rich layer agreed fairly well with the experimental results, by modelling the change of water permeability in the ice-rich layer in the tank. This analytical model is considered to be applicable to the design of ice storage tanks in DHC.
