The present paper reports the design, realization and testing of a lab-scale latent heat storage, specifically realized for solar cooling applications. The latent heat storage is based on a fin-and-tubes heat exchanger configuration employing a commercial paraffin as PCM. The paper mainly focuses on the experimental characterization, carried out by means of a test rig, available at the laboratory of the CNR ITAE, able to simulate working boundaries of a solar cooling plant. The experimental outcomes confirmed the increased heat storage density obtained by such a new component, compared to standard sensible heat storage. Nevertheless, still some limitations in the achievable heat transfer rate is highlighted, due to improper realization of the component.
