Abstract

The aim of this study is to investigate the experimental analysis of the thermal characteritics of a thermal energy storage (TES) unit that combines both sensible and latent heat stored in a bed. A TES unit is created, constructed, and integrated with a constant temperature bath to evaluate the functioning of the storage unit. For smaller temperature change Latent Heat Storage (LHS) has high storage density, but LHS has many practical problems, for example poor conductivity of Phase Change Materials (PCM). To overcome these introducing fins in PCM holders are best solution. In the current study, research is conducted to estimate the effectiveness of a thermal energy storing system for storing heat energy within spherical capsules containing stearic acid PCM and featuring hollow cylindrical fins inside. Stearic Acid with melting point of 57⁰C is used for investigation because local companies readily supply it and it is suitable for thermal storage purposes. The heat transfer fluid which is used to move heat from the source to the TES tank is water. The changes in temp difference of PCM has been examined for two configurations of PCM spherical capsules, one is without fin and another is with internal hallow cylindrical fins. While conducting experiments by increasing flow rate of heat transfer fluid from 2 lpm to 6 lpm the decrease in charging time is observed with a % of 32 and 36 for the case of without and with fin configurations. The quantity of immediate heat retained and the overall accumulated heat retained are greater in a spherical capsule featuring an internal hollow cylindrical fin configuration compared to a configuration without fins.
