An experimental and numerical analysis of an improved thermal storage tank with encapsulated PCM for use in retrofitted buildings for heating

In the building sector, 40% of final energy is used for heating and cooling. Up to 75% this in residential buildings. It necessary take a step forward reduce share consumption, particular through use efficient technologies their integration into system renovation buildings, which major challenge future research field. An important technology achieving goal heat storage, where phase change materials as storage material allows higher density. The main advantage using solution problem temporal divergence demand possibility from renewable sources, e.g. such solar energy. Solar resource can be during day, when production than demand, storing later period demand. This also improves efficiency generators thermal integrated. focus present study on investigation (PCM) conventional water tank storage. A comparison was made between sensible hybrid latent tank, PCM encapsulated cylindrical nodules integrated improve density tank. results experiment showed that 15% inside increases 70% over with only inside. measured experimental data were compared simulation TRNSYS model enable further analysis improvement integration.
