Adsorption refrigerator using monolithic carbon-ammonia pair

This paper presents the description of a laboratory prototype of an adsorption cooling machine which uses an activated monolithic carbon-ammonia pair. The design is focused on the generator consisting on aluminium and monolithic carbon discs. A numerical model of the generator based on the mass and energy conservation equations is developed. The heat transfer model (between aluminium fin and activated carbon-ammonia pair) is validated by comparing computer simulation and experimental results at ice maker operating conditions corresponding to tropical use (the evaporating and condensing temperature ranges are -20 degrees C to 0 degrees C and 20 degrees C to 45 degrees C, respectively).
