Experimental Research on Solidification Characteristics of Spherical Capsule Packed Bed Latent Heat Storage System

Abstract:

A thermal energy storage unit laboratory with solar heat sources being designed and constructed. The spherical capsules which filled in phase change material (PCM) were put into the unit. Many groups' experiment schemes was designed and the discharging experiment is done, different import temperature and flow rate of HTF were experimented repeatedly, the effects of inlet fluid temperature and flow rate of HTF on the performance of the storage unit was analyzed. The experimental result shows that, with the import temperature and flow rate of HTF increased, the time finishes discharging reducing constantly, the efficiency of thermal energy storage is improved. The results offer the reference basis for design, optimization, and appreciation of the TES unit.The test data was compared with simulation data,the simulated results and experimental results agree well with the experimental results.
