An innovative cold energy storage system, conceived for a civil application and based on the solidification and the fusion of a PCM (Phase Change Material), is presented and assessed. Firstly, a proper active material (phase transition temperature = 5-8øC, latent heat > 200 kJ/kg, immiscibility with water, no subcooling) is selected: after a detailed analysis of the PCM state-of-the-art and of the materials properties, the paraffin RT5HC produced by the company Rubitherm is selected. Then, an innovative heat exchanging system, able to speed up the tank charge and discharge, is presented and described. A 5 kWh prototype is tested, demonstrating the capability to be fully loaded at 4-5 kW in just one hour. By this patented high-power technology and thanks to the high latent heat of the packed PCM allowing to reduce the occupied volume, the storage tank can be integrated in a air conditioning-user system with a "peak shaving" strategy, leading to an optimization of the chiller operation and to an energy saving for civil air conditioning by 20-30%.
