摘要：

For deploying the dynamic-type ice storage system to district heating and cooling system (DHC), the effects of ice content (ice packing factor, IPF) and mass flow rate of supplying ice-slurry on the ice storing characteristics in a tank were investigated both experimentally and analytically. By raising IPF and reducing mass flow rate of supplying ice-slurry, the ice-rich layer was hard spreading horizontally in the tank. The overall porosity of the ice-rich layer was converging 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 with the experimental results, by modeling 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. (C) 2004 Elsevier Ltd and IIR. All rights reserved.
