Numerical simulation and experimental analysis of a latent thermal energy storage for naval applications

his paper aims at experimentally evaluate the performance of a compact sensible/latent thermal energy storage (TES) for application on cruise ships. A lab-scale proof-of-concept was designed, by using commercial macro-encapsulated phase change materials (PCMs), to achieve high storage density and good charging/discharging rate. The design proposed for the prototype is suitable for modular operation and to allow an easy scale-up up to full-size. An experimental campaign was realized at CNR ITAE to assess the charging/discharging behavior of the system. The experimental outcomes demonstrate that the proposed solution can help saving up to 25% of the required volume, thus making it more attractive for on-board applications.
