Experimental methods for the Characterization of Materials for Sorption Storage

The present chapter deals with the main experimental characterizations available to measure the performance of sorbent working pairs used in sorption TES. The experimental methods for the evaluation of equilibrium sorption curves and the models for the sorption equilibrium description are introduced. Furthermore, theoretical and experimental approaches for the heat of sorption evaluation are defined and some examples, reported in the literature, about the thermal storage capacity evaluation of different working pairs are reported.
