Heat energy storage systems offer the benefits of high energy storage efficiency and consistent temperature due to the use of phase change material (PCM); however, its disadvantage is that thermal energy storage takes longer to complete due to the material poor thermal conductivity.
Author to whom correspondence should be addressed. Shell-and-tube latent heat thermal energy storage units employ phase change materials to store and release heat at a nearly constant temperature, deliver high effectiveness of heat transfer, as well as high charging/discharging power.
One of the main challenges for latent thermal energy storages is the phase change itself which requires a separation of the storage medium and HTF. Furthermore, PCMs usually have a low thermal conductivity, which limits the heat transfer and power of the storage.
Heat pipes have been used extensively in a variety of energy storage systems. They are suited to thermal storage systems, in particular, in the role of heat delivery and removal, because of their high effective thermal conductivity and their passive operation.
The latent heat capacity is 198 kJ/kg and the density is 1480 kg/m 3. The PCM volume of the module was 7.8 l, which corresponds to a latent heat storage capacity of 0.64 kWh per module. The modules are installed in a floor-standing unit that is suitable for installation in both new and existing buildings.
