Experimental Study on Adsorption Refrigeration System with Stratified Storage - Analysis of Storage Discharge Operation

Intergrating heat recovery can improve the coefficient of performance (COP) of adsorption refrigeration system, and stratified storage enables recovery of a large fraction of the total heat that can be recovered in an ideal cycle. In some applications, like solar cooling or CHCP, the stratified storage unit used for heat recovery between adsorption and desorption half cycles can serve an additional purpose as a buffer storage for the heat driving the cycle. In this study, two experiments, based on the adsorption refrigeration test platform of Karlsruhe Institute of Technology (KIT), were conducted to research the variations of cooling capacity and COP when the system was disconnected from any other heat source but the storage, i.e., in a storage discharge operation mode.
