%X Recently the concept of combined power and cooling cycles using ammonia-water mixture as the working fluid has attracted much attention, since such systems may offer a reasonable arrangement of energy and exergy flow. In this work thermodynamic performance analysis of combined thermal power and cooling cogeneration cycle using ammonia-water mixture as the working fluid is carried out for efficient use of low-grade heat sources. The cycle is a combination of Rankine cycle and absorption refrigeration cycle, and is investigated parametrically for the purpose of extracting the maximum utilization from a given heat source. A special attention is paid to the effects of important system parameters including turbine inlet pressure, ammonia concentration, and absorber temperature on the performance characteristics of the cycle. Results show that thermodynamic performances of the system are sensitively influenced by system parameters.
