The objective of this work is to test and characterize a falling-film evaporator in a lab-scale adsorption test bench realised at Politecnico di Milano labs. Several ad/desorption cooling cycles were performed setting 15 – 20, 25, and 90 °C the heat transfer fluid temperatures for the evaporation, condensation/adsorption and desorption processes respectively. Preliminary evaluation of performance confirmed an evaporation cooling power of 2.5 – 3.5 kW depending on the refrigerant charge level and operating conditions. The overall heat transfer coefficient UA measured was in the range of 620 – 640 W/K.
