Experimental and theoretical analysis of the kinetic performance of an adsorbent coating composition for use in adsorption chillers and heat pumps

摘要

The present work aims at the experimental evaluation of the kinetic performance achievable by an innovative binder-based coating developed for application in adsorption chillers or heat pumps. It employs a commercial SAPO 34 as adsorbent material and a clay as binder. Samples with different thickness were prepared at the CNR-ITAE labs and their adsorption kinetics has been tested with a volumetric apparatus based on the Large Pressure Jump (LPJ) approach, available at the Fraunhofer ISE labs. For comparison purposes, also two representative loose adsorbent grain configurations, namely monolayer and multilayer, have been tested.
