“…One of the most employed methods is the Eco-indicator 99 (EI99) [26] , which is a global environmental indicator that encompasses eleven impact categories in a single score. Recent exergoenvironmental assessments have focused on a natural gas combined cycle with the integration of carbon capture and storage (CCS) and concentrated solar energy storage systems [27] , and a eucalyptus biomass power plant [28] . Comprehensive exergoeconomic and exergoenvironmental analyses were developed for a system that combined a gas and steam turbine system and a solar field [29] .…”

“…The environmental analysis of the system is done by using Life Cycle Assessment (LCA). Cavalcanti et al [23]have analyzed two CO 2 capture and storage and concentrated solar power systems in order to decrease the greenhouse gases from an exergoenvironmental viewpoint for a plant of the natural gas combined cycle for power production. Sanaye et al [24]have investigated a combined cooling, heating, power, and water system from energy, exergy, exergoeconomic, and exergoenvironmental (4E) viewpoint.…”

This paper aims to provide comprehensive 4E (energy, exergy, exergoeconomic, and exergoenvironmental) and advanced exergy analyses of the Refrigeration Cycle (RC) and Heat Recovery Refrigeration Cycle (HRRC) and comparison of the performance with R744 (CO2) and R744A (N2O) working fluids. Moreover, multi-objective optimization of the systems has been considered to define the optimal conditions and the best cycle from various perspectives. In HRRC, heat recovery is used as a heat source for an organic Rankine cycle. The energy and exergy analysis results show that utilizing HRRC with both refrigerants increases the coefficient of performance (COP) and exergy efficiency. COP and exergy efficiency for HRRC-R744 have been obtained 2.82 and 30.7%, respectively. Due to the better thermodynamic performance of HRRC, other analyses have been performed on this cycle. Exergoeconomic analysis results show that using R744A leads to an increase in the total product cost. Total product cost with R744 and R744A have been calculated by 1.56 $/h and 1.96$/h, respectively. Additionally, to obtain the processes' environmental impact, Life Cycle Assessment (LCA) is used. Exergoenvironmental analysis showed that using R744A increases the product environmental impact by 32%. Owning to the high amount of endogenous exergy destruction rate in the compressor and ejector compared to other equipment, they have more priority for improvement. Multi-objective optimization has been performed with exergy efficiency and total product cost objective functions as well as COP and product environmental impact for both refrigerants, which indicates that HRRC-R744 has better performance economically and environmentally. In optimal condition, the value of exergy efficiency, total product cost, COP, and the product environmental impact have been accounted for by 28.51%, 1.44 $/h, 2.76, and 149.01 mpts/h, respectively.

“…Today's main interest within the energy sector is finding cheap and environment-friendly alternative power production systems because of increasing environmental problems and decreasing primary energy sources (i.e. fossil fuels) [1][2][3]. In this context, the main scientific focus is on renewable energy sources such as biofuels [4], wind [5], and solar [6] energies, which are effectively unlimited but currently expensive to convert into usable energy [7].…”
