SOLAR GAS-DRIVEN ABSORPTION HEAT-PUMP SYSTEMS

This paper describes the potential for the development of hybrid gas/s olar-driven heat-pumps with the specific examples of a combined refrig eration and power-generation system and a sea-water purification syste m. Thermodynamic analysis has been performed on the systems using the water-ammonia and the lithium-bromide-water combinations. A desalinati on plant of this type is shown to have scope for a higher water yield than conventional solar stills, and the refrigeration system shows hig h efficiency coupled with flexibility of operation.
