摘要

For an application of the Dynamic -type Ice Storage System to the District Cooling and Heating System, the effects of ice content (IPF) and mass flow rate of supplying ice - slurry on the ice storing characteristics in a tank were investigated by experiments and analyses. In the analytical model, we considered that the ice - rich layer would be ununiform by raising of IPF and the water permeability in the ice -rich layer increases. By raising of IPF and reducing of mass flow rate of supplying ice - slurry, ice-rich layer could not spread in a tank. The porosity of ice - rich layer was contracting to the value of 0.8 - 0.9 in the ice storing process. The stored ice quantity depends on distribution and porosity of ice - rich layer in a tank decreased to 10% by raising IPF from 2.5wt% to 10wt% and reducing mass flow rate as constant ice flow rate. The analytical results could express the experimental results about stored ice quantity. Our analytical model is considered to be applicable to prediction of the ice storing characteristics and to design of an ice storage tank.
