The use of a Kalina cycle (KC) with a superheater to recover waste heat from an internal combustion engine (ICE) is described in this paper. The thermodynamic and economic analyses are performed for KC. The results indicate that using KC with a superheater is a feasible method to recover waste heat from ICE. The maximum thermal efficiency of KC is 46.94% at 100% ICE percentage load. The improvement of thermal efficiency is greater than 10% at all ICE loads, and the maximum improvement of thermal efficiency is 21.6% at 100% ICE load. Both the net power output and thermal efficiency of the KC subsystem increase with ICE percentage load and ammonia mass fraction. A lower turbine inlet pressure leads to a higher net power output of KC and a greater improvement of thermal efficiency when the ammonia mass fraction of the mixture is greater than 0.34. In the paper, if the same KC, which uses the largest capital investment, is used at different ICE loads, the payback period decreases with ICE load and ammonia mass fraction. In addition, both longer annual operation times and lower interest rates lead to shorter payback periods. However, it is worth noting that the payback period will be longer than the ICE's lifetime if the ICE load is low and the annual operation time is too short.Energies 2018, 11, 3044 2 of 19 recover more than 6 kW of mechanical power from long-haul trucks waste heat, but the system would be very heavy and large. Wang et al. [7] proposed a dual-loop ORC system with R1233zd and R1234fy as the working fluid and found that this system could get better performance for similar applications than other ORC systems. Scaccabarozzi et al. [8] showed that a supercritical ORC using the optimal mixture has better thermal performance for heat recovery from heavy duty ICEs. Liu et al. [9] found that both the exergy efficiency and thermal efficiency of the MC/ORC system decreases linearly with the reduction of engine load. Wang et al. [10] illustrated that Double loop ORC (DORC) can increase the efficiency of the combined system by 12% at 60-100% engine load.In addition to ORC, KC also shows good thermal performance for waste heat recovery due to its thermal match in heat exchangers during the heat transfer processes. Since Kalina [11] introduced KC using an ammonia-water mixture as the working fluid, many studies have been performed on KC. When KC was used as a bottoming cycle in combined cycle power plants, the thermal efficiency of KC was 30-60% higher than that of the Rankine cycle [12]; Fu et al. [13] found that compared to several other power cycles, using KC leads to an effectiveness enhancement of approximately 20% [13]. Hettiarachchi et al. [14] compared the performance of ORC and Kalina cycle system 11 (KCS11) for recovering low-temperature geothermal heat resources. They found that KCS11 has a better overall thermal performance at moderate pressures than that of ORC. Singh et al.[15] used a KC as the bottoming cycle to recover the waste heat from a coal-fired steam power plant. They found that there is a...

Fuel cell and renewable-based poly-generation plants (PGPs) are proven as advanced technologies for multiple generation purposes. To limit the greenhouse gas emissions, an innovative PGP generating electricity, cooling, desalinated water, and hydrogen is proposed in the current study. The system consists of a solid oxide fuel cell as a prime mover integrated with a gas turbine, a biomass combustion chamber, an organic Rankine cycle, an ejector refrigeration cycle, a desalination unit, and a proton exchange membrane electrolyzer integrated with solar collectors. As the most effective tools for performance evaluation, exergoeconomic, and environmental analyses have been applied. The system produces electricity of 4.4 MW, refrigeration capacity of 0.16 MW, and desalinated water of 0.96 kg/s. The attained freshwater enters the electrolyzer during 12 daylight hours, leading to hydrogen and sanitary water generation with the values of 1.55 g/s and 0.94 kg/s, respectively. The cost per unit exergy and the total cost rate of the products are 11.28 $/GJ, 223 $/h, correspondingly. Carbon dioxide emission of the system is estimated to be 10.79 kmol/MWh. According to the evaluation, the total cost rate increases with increasing current density and fuel cell inlet temperature and decreasing fuel utilization factor.

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.
