Effect of a latent heat thermal energy storage unit used in project

The latent heat thermal energy storage system using phase change material (PCM) is quite attractive, mainly due to their high energy storage density and their ability to provide heat in a narrow temperature range. A latent heat thermal energy storage unit is designed, which is installed conveniently and have a fast period of charge and discharge. The latent heat thermal energy storage unit is applied to a demonstration project in conjunction with solar collectors and tank. Results showed that the designed unit in this paper eases the large fluctuations of water temperature in tank and make the system work more stably. The latent heat thermal energy storage unit plays a significant role in project.
