A water-ammonia absorption refrigeration (AAR) system is preferred to class
ical vapour compression when a heat source is available cheaply. This study
deals with the analysis of an AAR system operating with a low-temperature
heat source. Eleven design variables were chosen for this purpose. The anal
ysis showed that the use of a low temperature heat source imposes some rest
rictions on the system design, but an economically operating AAR system may
be designed by a careful process optimization study.
