Abstract

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 of 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°C to 0°C and 20°C to 45°C, respectively).
