“…These exergy efficiency values are promising when compared to other combined cycles. Sun et al [12] achieves up to 42.0% of exergy efficiency at a turbine temperature of 350°C, which is very high compared with the single stage case (η exergy,e f f = 3.64%), but is also low compared to the multiple stage case (η exergy,e f f = 68.0%).…”

This paper presents a theoretical investigation of a combined Power and Cooling Cycle that employs an Ammonia-Water mixture. The cycle combines a Rankine and an absorption refrigeration cycle. The Goswami cycle can be used in a wide range of applications including recovering waste heat as a bottoming cycle or generating power from non-conventional sources like solar radiation or geothermal energy. A thermodynamic study of power and cooling co-generation is presented for heat source temperatures between 100 to 350°C. A comprehensive analysis of the effect of several operation and configuration parameters, including the number of turbine stages and different superheating configurations, on the power output and the thermal and exergy efficiencies was conducted. Results showed the Goswami cycle can operate at an effective exergy efficiency of 60-80% with thermal efficiencies between 25 to 31%. The investigation also showed that multiple stage turbines had a better performance than single stage turbines when heat source temperatures remain above 200°C in terms of power, thermal and exergy efficiencies. However, the effect of turbine stages is almost the same when heat source temperatures were below 175°C. For multiple turbine stages, the use of partial superheating with Single or Double Reheat stream showed a better performance in terms of efficiency. It also showed an increase in exergy destruction when heat source temperature was increased.

“…A wide variety of combined absorption cycle configurations have been studied and reported in the literature for the combined production of power and cooling/refrigeration (Ayou et al 2013a;Yu et al 2014;Hua et al 2014;Sun et al 2013). The literature on the combined absorption cycles has found that greater importance is given to power output than refrigeration.…”

“…Han et al [34] proposed an ammoniawater power/cooling cogeneration system which made full use of the turbine exhaust vapor and whose strong solution concentration could be adjusted. He also [35] proposed an ammonia-water power and cooling cogeneration using mid/low-temperature heat source, which consisted of a Rankine cycle and an absorption refrigeration cycle. The high-temperature portion of waste heat was used for power generation, whereas the low-temperature part was used for refrigeration.…”
