This paper presents the experimental results given by the operation of a chemical sorption
refrigeration system using Expanded Graphite/Activated Carbon/Lithium Chloride
(AC/GE/LiCl)-Adsorbent (NH3 in solution with a 25% concentration). Experimental protocol with
the characteristics of the experimental rig developed, working pair specifications and the procedure
that has developed in the process is described in detail. Results are presented for different behaviors of
the system, where the desorption stage is driven by forced convection. Measurements of the thermal
variables of the system show that the adsorption-desorption cycles in the test accomplished, with high
and low-pressure zones clearly defined. The cooling effects for the pair material studied have the
expected behavior for the mixture proposed.
