“…Table 7 shows the comparisons between the present calculation results and the data obtained from the references. It can be seen that the present mathematical model results showed a good agreement with the corresponding results from the works of Saleh [60] and Grauberger et al [26]. As a result of this, the present mathematical model can be accepted as validated.…”

“…Although there is not any study considering the same configuration with the proposed combined system in this study, there are some studies considering combined ORC-VCRC systems in the current literature. Hence, two recently reported works about the combined systems by Saleh [60] and Grauberger et al [26] are chosen for the validation of the present model. The configurations and operating conditions of these combined systems were taken as defined in the references.…”

“…They also observed that R600a was the best refrigerant for their proposed combined cycles. Grauberger et al [26] presented an experimental and numerical study on the ORC-VCR combined system using R1234ze(E) as the working fluid. In their study, a prototype ORC-VCR was designed, built, and tested at the standard rating conditions.…”

In this paper, an exergoeconomic and exergetic sustainability analysis of a dual-pressure organic Rankine cycle (ORC) and vapor compression refrigeration cycle (VCRC) driven by waste heat is performed for power generation and cooling production. In addition, the most suitable fluid couple among the thirty-five different fluid pairs was investigated for the proposed combined system. The results indicate that the highest energy utilization factor, exergy efficiency, the system coefficient of performance, and net power are calculated for the R123-R141b fluid pair. In terms of exergetic sustainability indicators, the best performance results are obtained for the R123-R141b fluid combination. The minimum unit electricity generation cost and the shortest payback period are calculated as 0.0664 $/kWh and 2.5 years, respectively, for the R123-R290 fluid pair. The system component with the highest exergy destruction is the boiler, with 21.67%. The result of the parametric analysis showed that the thermodynamic performance parameters increase with the increment of the ORC’s boiling temperature. In addition, with the increasing boiling temperature, the environmental effect factor of the system decreases, while the exergetic sustainability index increases. Additionally, as the boiling temperature increases, the total system cost increases, while the unit electricity production cost and payback period decrease. It is suggested to use a R123-R141b fluid couple among fluid pairs created as a result of thermodynamic, exergoeconomic and sustainability analysis.

“…The results showed that the R245fa exhibited the highest thermal efficiency of 25%, which was 29% higher than the 19.4% achieved using R1234yf under the same operating conditions. Grauberger et al [49] designed and evaluated an experimental ORC-VCRC of 300 kWth using novel heat integration strategies. The system uses a turbo-compressor sharing a single shaft.…”

“…From the literature reviewed, it is clear that there have been many studies of ORC driven with solar energy [60] for a wide range of applications. Also, many studies have been reported for the simultaneous production of power and cooling, but most of these studies integrate a VCRC into an ORC [47,49,50]. Also, many systems have used an ERC for cooling purposes [51][52][53].…”

Humanity is facing the challenge of reducing its environmental impact. For this reason, many specialists worldwide have been studying the processes of production and efficient use of energy. In this way, developing cleaner and more efficient energy systems is fundamental for sustainable development. The present work analyzed the technical feasibility of a solar-driven power-cooling system operating in a particular location in Mexico. The theoretical system integrates organic Rankine and single-stage absorption cooling cycles. A parabolic trough collector and a storage system integrated the solar system. Its performance was modeled for a typical meteorological year using the SAM software by NREL. The analyzed working fluids for the organic cycle include benzene, cyclohexane, toluene, and R123, while the working fluid of the absorption system is the ammonia-water mixture. The cycle’s first and second-law performances are determined in a wide range of operating conditions. Parameters such as the energy utilization factor, turbine power, COP, and exergy efficiency are reported for diverse operating conditions. It was found that the highest energy utilization factor was 0.68 when the ORC utilized benzene as working fluid at ORC and ACS condensing temperatures of 80 °C and 20 °C, respectively, and at a cooling temperature of 0 °C. The best exergy efficiency was 0.524 at the same operating conditions but at a cooling temperature of −10 °C.
