Experimental set-up and testing procedure for the assessment of sorption devices for long-term energy storage

Thermal energy storage systems have gained interest in recent years, both for cold and heat applications, daily or seasonal. Among them, thermochemical storage have shown great potentialities, but still only few experimental activities on prototypal systems are reported. Aim of the present paper is to describe a test set-up located at CNR-ITAE and devoted to the characterization of thermochemical storages. A testing procedure for the assessment of this kind of devices has been tested as well, proving a good starting point towards the definition of a more complete protocol.
