Abstract

Thermal energy storage systems by latent heat, in which phase change materials are used, are the subject of many scientific works. These systems are designed to guarantee the energy saving through promising technology. The present work concerns the experimental study of thermal performances of a latent heat thermal storage device made in our laboratory (ETAP). The PCM (paraffin) is stored in the vertical finned U-shaped tubes of the exchanger. The air is used as the heat transfer fluid. The storage unit use several identical heat exchangers filled with paraffin. The study examines the complete cycle with the two processes of charging (melting) and discharging (solidification) to analyse the effect of the numbers of exchangers on the thermal performance of the thermal storage. The obtained results showes that the storage unit with three exchangers stores 73 and 32% more thermal energy than a storage unit with one and two exchangers. At the end of the discharging duration, the first exchanger releases its total heat in Conf. 1, 2 and 3 respectively, after 126, 149 and 160 min
