“…The authors also carried out a thermo‐economic study and reported a minimum production cost of 130$/GJ. This cost is not so competitive since it is several times higher than the reported by Xia et al 82 and Huang et al 92 at similar heat source driven temperatures. Parikhani et al 107 carried out energy, exergy and thermo‐economic studies of a new system for the simultaneous production of power and cooling.…”

“…On the other hand, regarding thermo‐economic analysis, the minimum production costs were obtained with two systems integrating a Bryton cycle, an ORC, and an ECC. Huang et al 92 reported a value of 14.73$/GJ, while Xia et al 82 reported a value of 17.6$/GJ. It is important to mention that although the minimum costs of production were attained with these systems, both require temperatures higher than 400°C to operate, which are not too easy to get from industrial waste heat or from renewable energies.…”

Summary A comprehensive review of thermodynamic cycles for the simultaneous production of power and cooling is presented. The study not only actualizes the bibliographic reviews previously realized by other authors regarding cycles such as Kalina, Goswami, or modifications of them. This review additionally includes an overview of hybrid cycles and other novel cycles reported in the literature. The hybrid cycles included in the study are systems integrated by two or three conventional cycles, mainly composed of Brayton, Rankine, and ORC for power generation; and compression, absorption, and ejector cycles for cooling production. The other novel cycles mentioned are thermodynamic cycles, which considerably differ from all the others. By using internal rectification, the Goswami cycle increased its efficiency by about 5%; however, by adding diverse components, as a condenser and a subcooler, the efficiency was significantly improved due to the considerable increase of the cooling production. Organic Rankine cycles integrating absorption refrigeration cycles are, in general, the most efficient hybrid cycles, reaching thermal efficiencies close to 40% for the simultaneous production of power and cooling. If a third output was provided, as heating or water distillation, the energy efficiencies were as high as 90%. The main problem with these systems is that, in general, they are too complex and costly because of the considerable number of components. The highest exergy destruction values are reported in solar collectors when used, followed by boilers or generators, and absorbers. The lower production costs were reported with systems integrating a Brayton cycle, an organic Rankine cycle, and an ejector‐cooling cycle. The disadvantage of these systems is that they need high operating temperatures.

“…Compared to other waste heat activated refrigeration means, absorption refrigeration has advantages of large cooling capacity, high heat and mass transfer coefficient, and good flexibility to heat source variation. It is estimated that about 35% of fuel consumption in vehicle refrigeration are used for air conditioning, food cold storage, or other cooling requirements . The feasibility of waste heat activated absorption refrigerator used on vehicles were verified by the former researchers .…”

Waste heat exhausted from vehicle engine has significant influences on the performances of absorption refrigeration driven by vehicle exhaust heat (VARS), especially for the transient response of VARS to the exhaust temperature and flow rate. Moreover, ambient temperature and flow rate of solution pump also affect its performances. Based on these, a dynamic mathematical model of VARS was proposed and established to observe its dynamic performances in this work. Further, the dynamic model was solved, and the simulation results were compared to the experimental data of a prototype in the same operating conditions. Finally, the transient response of VARS to exhaust temperature and flow rate, ambient temperature, and flow rate of solution pump were analyzed. The simulation results showed that the response time is about 2000 seconds when a disturbance was imposed. The research findings can supply some guidance for a reliable design, optimization, and control strategy for the actual application of the VARS.

The present research has analyzed the energy and exergy of a combined system of simultaneous power generation and cooling. To provide a comprehensive data sheet of this system, the system has been investigated in the temperature range of 300–800 °C, and 6 working fluids, including air, carbon dioxide, nitrogen, argon, xenon, and helium, have been investigated. The parameters affecting the performance of the system, namely the compressor inlet pressure, the compressor pressure ratio, and the intermediation pressure ratio were investigated. The power produced by the Brayton cycle at a pressure ratio of 5.2 is the highest due to the increase in compressor power consumption and turbine power generation. The results of the parametric study showed that the exergy efficiency of the system has the maximum value at the pressure ratio of 4.73. The results of the parametric study showed that increasing the pressure of the compressor does not have a significant effect on the electricity consumption and the temperature of the working fluid due to the constant pressure ratio. The input energy to the heat exchanger of the absorption chiller decreases with the increase in the Brayton cycle pressure ratio, and as a result, the cooling created by the chiller also decreases. In this method, three objective functions of exergy efficiency, energy efficiency, and total production power are considered as objective functions. The most optimal value of intermediation pressure ratio was obtained after the optimization process of 1.389. Also, the most optimal value of the pressure ratio of high-pressure and low-pressure turbines was reported as 2.563 and 1.845, respectively.
