TOWARDS ENERGY EFFICIENT LATENT HEAT STORAGE TANKS WITH HEAT TRANSFER FLUID CHANNELS AND FINITE INLET POWER
Sinopsis
In this research, latent heat storage tanks are modelled with a water flow with a finite total heat capacity. Because of the finite heat capacity of the water flow, the Phase Change Material (PCM) will not melt uniformly. This is in contrast to the case were large water flows induce a constant wall temperature for the PCM. In this paper, we show that increased charging efficiencies can be obtained for high flow lengths and reduced PCM layer thicknesses. Additionally, both storage and charging performance increase for lower water volume fractions. Further, we show that multiple stage design enables improved charging performance and reduced pumping power requirements.
