摘　　要：本文搭建了中温壳管式熔融盐潜热储/放能系统,实验研究了不同质量流量对系统蓄/放热的影响,考虑到纯熔盐的低热导率不利于系统换热,本文采用添加泡沫镍的方法来强化纯熔盐的热导率,以提高系统的性能,并与纯熔盐系统进行了对比分析。系统的平均功率和效率用以评价该壳管式储/放能系统的性能。A shell-tube latent heat thermal energy storage/retrieval system was built using molten salt as the phase change material（PCM） to experimentally investigate the heat transfer characteristics of the system.Experiments with different mass flow rates were conducted to study the influence on the performance of the system.Nickel foam was embedded in the pure salt to enhance the performance of the system and the results of the nickel foam/molten salt composite PCM system were compared with those of the pure salt system.The average power and efficiency of the system were introduced to evaluate the performance of the system.
