Abstract: Solar energy coupling with energy storage is a popular technology in the energy field. How to achieve the high-efficiency application of solar energy is very important. Energy storage technology is the key issue in this aspect. Latent heat storage is a more efficient energy storage. In this paper, a visualization experimental platform of a latent heat storage system has been designed, and some performance data have been obtained. Hot water has been used as the heat transfer fluid, and paraffin wax has been used as the phase change material. The inclination angle of the tank is varied from the horizontal direction (0°) to the vertical direction (90°) by a step of 30°. The melting performance has been studied for three cases with inlet water temperature of 356 K, 361 K, and 366 K. The result shows that the inclination angle of the tank has a great influence on the melting process of the phase change material, and the temperature distribution of the material is obviously different. The result also shows that the testing point temperature (for testing point 1) varied from 341.31 K to 342.18 K when the inclination angle was 30° and 90°, respectively. However, the temperature of testing point 4 varied from 321.76 K to 335.03 K when the inclination angle was 30° and 90°, respectively. The results of this paper can provide a reference for the future pipe design and storage efficiency of latent heat storage systems.
