Abstract: Absorption cycles have been proposed not only for cooling but also for power generation, benefiting from temperature glide in heat exchangers, lowering exergy destruction. They can effectively utilise low-temperature solar, geothermal or waste heat. Apart from water-ammonia mixture, alternative working fluids may provide further advantages. Specifically attractive is an aqueous solution of salts such as lithium bromide (LiBr), also known from absorption cooling. Previous theoretical works found thermodynamic benefits of this concept mainly for heat sources around 100 °C and technical feasibility even for kW scale systems, but experimental works were limited.
