Abstract

As an important core equipment in the solar heating system, the performance of the hot water storage tank directly affects the overall operating efficiency of the energy storage system. In this paper, a phase-change heat storage device with a group of cylindrical phase-change unit is designed, and a phase-change hot water storage tank performance test platform is built. The temperature change curve of the heat storage device in heat release process is obtained through the single control variable method. Studies show that for a heat storage device with a certain space, when the mass of phase change material （PCM） is equal, the diameter of the phase change unit has little effect on the heat release rate of the device; the distance between the phase change units has a great impact on the device The effect of heat release rate is small; when the inlet flow rate of heat transfer fluid （HTF） is increased and the HTF inlet temperature is decreased, the heat release time of the heat storage device can be greatly reduced, and the overall performance of the heat storage device can be improved.
