Today, due to the reduction of fossil resources and on other hand high environmental pollution these resources, it is necessary pay attention alternative including clean available renewable resources. In this study, solar geothermal energy sources are combined, generating electricity, cooling, freshwater, hydrogen, along with selecting a suitable heat transfer fluid for parabolic trough collectors. This system consists collectors, steam Rankine cycle, cycle an organic proton exchange membrane electrolyzer, reverse osmosis desalination unit. To analyze performance Therminol 59, Marlotherm SH, Syltherm 800, VP1 fluids selected. Solar radiation intensity, collector mass flow rate, turbine pump efficiency, evaporator pinch-point temperature, inlet temperature were investigated as design parameters affecting performance. Maximizing efficiency reducing cost rate selected two objective functions determined using multi-objective sorting genetic algorithm (NSGA-II). The results showed that 59 has highest net power output compared fluids. Also, proposed produces 1140 kW electricity in optimal state, best 32.39% 36.32 $/GJ.

In this research, the optimization of energy consumption zero-energy buildings using PCMs in two study cities Vancouver and Dubai its supply with a multi-generation geothermal system is discussed. used walls roofs designed are types, namely PCM (solid) (liquid). By optimizing residential complex cities, it finally possible to choose best mode optimal conditions reduce complex, costs environmental pollution. The results showed that amount electricity consumption, heating, cooling during year city 8493.55, 7899.1, 1083.97 kWh, respectively, Dubai, values 9572.1, 8.99, 18,845.44 kW, respectively. Also, by complexes CO2 emissions 2129.7 2773.2 kg/year, 11.26% carbon dioxide emission 23.20% more. end, proposed meet six-unit 120 m2 bedrooms Vancouver, Canada. setting up 237,364.6 kWh electricity, 425,959.4 304,732.8 can be produced one year. According investigation, easily provide required buildings.

Опубликована: Май 20, 2024

The thermodynamic analysis of a geothermal-based integrated energy system to produce liquid hydrogen, cooling, hot water, and power was presented in this study. investigated made geothermal subsystems, modified organic Rankine cycle (ORC), PEM electrolyzer, hydrogen storage source. Different fluids including refrigerants R113, R123, R134a were increase the performance. Analysis showed that best fluid is R123 because it helps performance system. authors employed Design-Expert software RSM for optimum results purposes, objective functions chosen be exergy efficiency (EE) cost rate (CR). Following introduction design variables, mass flow input evaporator, temperature heat recovery vapor generator, turbine efficiency, temperature, evaporator pinch point pump their impact on system's investigated. optimal values EE CR ultimately found 43.91% 45.12 $/h, respectively. Also, research, seven regions within Canada launch proposed studied cities Victoria, Vancouver, Regina, St. John's, Dawson Creek, Whitehorse, Port Alberni. Finally, Regina superior electricity production at reasonable area. environmental city could help expand 5 hectares green space by producing 4993.03 MWh one year. findings indicated implementing suggested would prevent 1018.6 tons CO2/MWh from being emitted into environment yearly, only chipping 24445.9 $/ton CO2 per
