Summary

Despite absorption/resorption refrigeration systems were first proposed long time ago, these systems have been much less studied than the compression/resorption refrigeration systems. Just a few experimental ammonia/ water absorption/resorption plants have been built and tested over the last years and much more research work have to be done. The main advantage of the absorption/resorption refrigeration cycles in comparison to the conventional absorption cycles is the wide operation flexibility and the possibility of reducing the high working pressure in a very significant way. However, several authors have reported the difficulty of working under stable conditions. This paper aims to review the theoretical and experimental works carried out so far on these systems. Furthermore, a thermodynamic model is presented to be used for analysing the operation flexibility provided by these systems and the influence of the pressure ratio and the effectiveness of the solution heat exchangers on the performance of the cycle.
