Testing a New Design of Latent Storage
Abstract
A modified spiral plate heat exchanger used as latent storage module for direct steam generation was proposed in the REELCOOP project. Under the failure of eight other phase change materials claimed in the literature as potential latent storage media, the phase change material used to meet the temperature range needed is the Hitec® salt. This paper presents the melting/ freezing tests performed with the Hitec® salt previous to its use in the storage module, the general scheme of the experimental facility constructed at the Plataforma Solar de Almeria, as well as the acquired know-how during the filling of the TES module and the commissioning of the facility.
