Study on Combined Latent-and Sensible-Heat Thermal Energy Storage : 2nd Report, Optimization of Unit in Relating with Operating Conditions

Abstract

A combined type of latent-and sensible-heat thermal energy storage (TES) is proposed, and it-s performance is investigated experimentally and theoretically. The theoretical treatment is made taking in account recirculating flow in the capsule. In comparison with the theoretical answers and the experimental results given by preceding report, the optimum design of TES is determined in relation with the operating conditions and Phase Change Material (PCM).
