研究了直接接触式潜热储能器在放电过程中的性能。所用的储存介质是硫代硫酸钠五水合物，其熔化温度为48 ℃，热交换流体是传热油。提出了计算容积传热系数的经验公式。还发现集总分析非常适合于分析存储介质的温度及其固体分数，包括离开存储器的油的温度。计算结果与实验结果吻合较好。(C)1999爱思唯尔科技有限公司。保留所有权利。
Performance of a direct-contact latent heat energy storage during discharging process has been investigated. The storage medium used is sodium thiosulphate pentahydrate of which the melting temperature is 48 degrees C and the heat exchanging fluid is heat transfer oil. An empirical expression to evaluate the volumetric heat transfer coefficient has been carried out. A lumped analysis is also found to be quite suitable to analyze the temperature of the storage medium and its solid fraction including the temperature of the oil leaving the storage. The results agree well with those of the experiments. (C) 1999 Elsevier Science Ltd. All rights reserved.
