This work presents an energy/exergy analysis to investige performance of thermal storage unit which loaded with a commercial phase change material (Plus ICE H190). The influence of fluid parameters on the energy/exergy effectiveness was examined. The temporal changes of the energy and exergy rate and performace of the storage unit are obtained  in the results. Latent heat principle is considered an efficient method to gain a higher effectiveness of system from an energy and exergy aspects. The fluid mass flow rate during charging and discharging periods were 2.50 kg/min and 1.26 kg/min, respectively. The results showed a significant increase of thermal resistance on the thermal storage unit performance. Fluid and phase change material show significant temperature difference on the rate of energy/exergy quantites and the time of melting or soldification. Ther results indicated that the average rate of energy and exergy were 1.3 kW and 0.54 kW, respectively. Wheras, energy and exergy  average rate during discarging periods were 1.1 kW and 0.31 kW, respectively. Also, the global rate during the experimetal periods were about 84% and 54%, respectively.

This paper addresses a simulation investigation of a fin-tube thermal storage unit involving phase change process dominated by heat conduction. The heat transfer of fin-tube thermal storage unit with phase change material (PCM) was simulated by Fluent. Graphical results including outlet temperature of heat transfer fluid (HTF), average temperature of PCM and phase front interface of solid and liquid phase of PCM versus time and fin distance were presented and discussed. According to simulation results, it was concluded that only the fin-tube thermal storage unit with fin distance of 12fin/inch could satisfied the request of heat release performance of household heat pump water heater for shower.
