内通流体套管式潜热蓄热器充放热过程的实验分析

An experimental study of thermal storage for a circulartube phase change accumulator with heat transfer fluid flowing inside

通过建立与工业实际相似的加肋同心套管式潜热蓄热器模拟实验台,对潜热蓄热器内通流体时的充热、放热过程进行了实验研究。实验得出了流体的出口温度、充热量和放热量随时间的变化规律。

This article describes the phase-change latent heat storage in an experiment device with inner longitudinal finned casing-pipe that is similar to the industrial ones, and discusses the influences of fluid velocity, inlet temperature and charging or discharging time on the charging and discharging process. Then it analyses the relationship between the out-conditions and the charging and discharging heat quantity.
