“…Table 2 shows a summary of the main results obtained by these studies and some contradictions in the obtained results. 14 Other researchers try to enhance the ejector performance by proposing new or adapted ejector geometries. As summarized in Table 1, these propositions include the use of a spindle tuning ( Figure 6A), 34 dual-nozzle ejector ( Figure 6B), 35 nozzles with different exit-port shapes, [37][38][39] tow-stage ejector, 40,41 and variable ejector geometry.…”

Cooling and refrigeration systems consume around 17% of the worldwide electricity. Enhancing the performance of these systems, using renewable energy resources and waste heat recovered from industrial processes, will lead to reduced fossil fuel consumption. Improvements of these systems using ecofriendly working fluids are of equal importance. Both options contribute to the minimization of the emissions of greenhouse gases and ozone depletion substances. In this paper, a detailed and comprehensive review of the innovative and improvement approaches of the thermo-mechanical refrigeration (TMR)

“…One example is absorption and adsorption refrigeration, which holds a lot of promise when waste or renewable heat is available. Other thermally driven alternatives are ejector refrigeration systems, which, like sorption technologies, perform work without moving parts based on low‐temperature thermal resources . An alternative technology presently available in the market is thermoelectric cooling, which utilizes the Peltier effect.…”

The need for energy‐efficient and environmentally friendly refrigeration, heat pumping, air conditioning, and thermal energy harvesting systems is currently more urgent than ever. Magnetocaloric energy conversion is among the best available alternatives for achieving these technological goals and has been the subject of substantial basic and applied research over the last two decades. The subject is strongly interdisciplinary, requiring proper understanding and efficient integration of knowledge in different specialized fields. This review article presents a historical and up‐to‐date account of the energy‐related applications of magnetocaloric materials and information about their processing and magnetic fields, thermodynamics, heat transfer, and other relevant characteristics. The article also discusses the conceptual design of magnetocaloric refrigeration and power generation systems and some guidelines for future research in the field.

“…Thermodynamic analysis of systems composed of an ORC and an ejector refrigeration cycle (ERC) has been widely carried out by numerous researchers. 22 A solardriven system comprised of an ORC and an ERC was analyzed by Ahmadzadeh et al 23 from thermal and exergoeconomic perspectives. The results showed that the cost rates of produced cooling load and electricity are 0.08 $/h and 3.59 $/h, respectively.…”

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.
