摘要
A new thermal storage system using multiple phase change materials (PCMs) is developed. It consists of several shell-and-tube thermal storage exchangers, which are connected in series to improve the system efficiency. Each exchanger uses a different PCM To reach optimal system efficiency, the melting points of the PCMs are carefully selected according to a thermodynamic optimization analysis. A finite element model is developed to simulate the cyclic thermal process in the multi-exchanger system. Computations were carried out for a three-exchanger system to investigate the advantages of the multiple-PCM system over the conventional single-PCM system. Simulation results were compared and found to be in good agreement with the results of a thermodynamic optimization analysis.
