Alml~ct--This study presents a novel power generating cycle suitable for solar energy applications. A modified version of the conventional LiBr-H20 absorption refrigerating machine is used for the proposed cycle. The condenser, expansion valve and evaporator are replaced by a superheater and a steam turbine, while a flashing tank replaces the generator. The cycle is powered by medium concentrators with a solar collecting temperature of 165Β°C. Steam generated in the flashing tank (100 kPa) is superheated (using fuel) to 600Β°C before it expands in the turbine down to 1.25 kPa. This is maintained by the equilibrium conditions in a water cooled absorber, LiBr-H20 solution is directly circulated in the solar collectors and the non-solar energy input to the system is 23% of its total requirements.
Results showed that using a 710 ton refrigeration absorption machine, the SFAPC would generate 960 kW shaft power at a system thermal elF~iency of 25% which is 44% higher than the available systems. Moreover, when the SFAPC is combined with a vapour compression refrigerator, an overall COP of 1.4 is obtained. This is 72% higher than that of the absorption machifie alone at the expense of 23% non-solar energy supply.
