Vapour Absorption Heat Transformers (VAHT) have shown good potential for upgrading waste heat to useful temperature levels. VAHT can be effectively coupled with Multi Effect Desalination (MED) systems for water purification. In this study an exergetic analysis is carried out for VAHT integrated with MED. A simulation model has been developed to evaluate the exergetic efficiency, exergy losses in the components and exergy balance of the system. The effects of operating parameters such as heat source temperature, sink temperature, effectiveness of solution heat exchanger are evaluated on the performance of the system. Exergy efficiency varies from 11.14% to 35.35% depending upon the temperatures of heat source and sink. It is found that the highest exergy loss is in the condenser of VAHT, followed by second effect of MED.
