A Latent Heat Storage System for Low-Temperature Applications: From Materials Selection to Prototype Performances

The industrial sector is increasingly obliged to reduce its energy consumption and greenhouse gases emissions contribute the world organizations’ targets in transition. An efficiency solution lies development of thermal storage systems, which are notably lacking low-temperature range (50–85 °C), for applications such as district heating or waste heat recovery. This work aims bring a latent from material selection prototype evaluation. first part this paper dedicated characterization aging phase change selected screening literature (fatty acid mixture mainly composed by stearic palmitic acid). Then, encapsulated tested whose performances evaluated under various operating conditions. Finally, numerical model validated experimental results used explore influence wider conditions, dimensioning choices, conductivity improvements.
