Effect of Inner Velocity and Temperature on Outer Ice Accumulation in Ice Storage
The ice storage air conditioner plays a vital role in the energy consumption of buildings, economic cost, and peak-load regulation of the electricity grid. However, the effects of different flow in the tube of ice storage tank, which is the key component of ice storage air conditioning system, on th...

| description | The ice storage air conditioner plays a vital role in the energy consumption of buildings, economic cost, and peak-load regulation of the electricity grid. However, the effects of different flow in the tube of ice storage tank, which is the key component of ice storage air conditioning system, on the ice layer have not been clearly determined, and there is a lack of studies on the influence of nanofluid on ice storage. In this study, the inlet conditions of cold storage materials and the influence of the volume fraction of nanocomposite phase-change materials on the solid-liquid phase change and temperature in the cold storage process are investigated, and the optimal cold storage conditions are obtained via numerical simulation. The results show that the effect of the inlet velocity is smaller than that of the temperature, and an increase in the inlet velocity decreases the temperature difference between the inlet and outlet, which results in a more uniform temperature distribution. The addition of nanoparticles improves the efficiency of the ice accumulation, and the volume fraction of the nanoparticles is the most important factor because it may decrease the efficiency. |
