    Abstract

    The thermodynamic analysis and the pilot plant design are described for a solar assisted double-effect absorption refrigeration system. The working fluid is ammonia/water (NH3-H2O). Theoretical COP values are presented. The double-effect system is comprised of a primary solution circuit operating at a relatively high temperature, pressure and low ammonia concentration and a secondary circuit operating at higher ammonia concentration. The primary circuit is comprised of a generator, a solar generator, two solution heat exchangers, and an absorber. The secondary circuit includes two solution heat exchangers, two absorbers, and a low temperature, low pressure generator, which operates as a second evaporator. The two circuits are interfaced by a condenser and evaporator. Refrigerant from the primary circuit's generator flows, in sequence, to the condenser, the evaporator, and then to the secondary circuit's absorber. For the pilot plant design, the gas and solar generators are simulated using electric heaters (operating at 65.5 deg. C). Vessel design includes falling film absorbers with innovative drippers, generators with distillation columns and reflux condensers, falling film evaporators, and concentric tube in tube solution heat exchangers.
