This paper presents an exergetic analysis of a combined power and cooling cycle that uses ammonia-water mixture as working fluid. Such cycles, use solar or geothermal energy or waste heat energy from a conventional power cycle. Ammonia-water power cycle can be used as independent cycles to provide power output and cooling. For a range (25-55 Bar) of boiler pressure the performance of the combined power and cooling cycle is investigated. The exergy of the boiler is very low compared to its energy. There is a boiling process and a heat transfer process at low temperature, both of which destruct the energy given to the boiler, so that the energy efficiency is low; however the exergy efficiency is higher than the energy efficiency. Increasing the turbine inlet pressure decreases the energy and exergy efficiencies.eninfo:eu-repo/semantics/openAccessAmmoniaBoilersCoolingEnergy efficiencyExergyHeat transferTemperatureWaste heatWaste heat utilizationWater powerAmmonia-water mixtureConventional powerEnergy and exergy efficiencyExergetic analysisExergy efficienciesHeat transfer processLow temperature heat sourcesTurbine inlet pressureGeothermal energyAmmoniaBoilersCoolingEnergy efficiencyExergyHeat transferTemperatureWaste heatWaste heat utilizationWater powerAmmonia-water mixtureConventional powerEnergy and exergy efficiencyExergetic analysisExergy efficienciesHeat transfer processLow temperature heat sourcesTurbine inlet pressureGeothermal energyConference Object130120921310.12693/APhysPolA.130.2092-s2.0-84987837362Q4WOS:000384810700055Q4
