Résumé

The use of a Latent Thermal Energy Storage (LTES) system using suitable Phase Change Materials (PCMs) is an effective way of storing energy because of its high-­energy storage density and isothermal nature of the storage processes. Unfortunately, PCMs present a few unfavorable thermophysical properties, among those the low thermal conductivity, which are limiting the
development of efficient, reliable and convenient LTESs. However, LTES represents a promising technology, which can unlock unprecedented opportunities for multiple-­sources energy integration, waste heat recovery, and efficient energy management. This paper aims at investigating new 3D periodic structures obtained via metallic additive manufacturing developed to enhance the phase change process during both loading and unloading processes of different paraffin waxes and sugar alcohols. The tests were run by imposing 20 W during the loading process and the monitoring the temperature distribution within the PCM.
