In this paper, results from comprehensive thermoeconomic assessments of small-scale solar organic Rankine cycle (ORC) systems are presented based on weather data in London, UK, which is taken as representative a temperate climate with modest temperature changes, mild winters and moderate summers. The consider range of: (i) collector types (flat-plate, evacuated-tube, evacuated flat-plate collec...

Recently, many countries have paid substantial attention to power generation from biomass gasification, particularly through small-scale plants. A number of power plant models have been suggested and analyzed; however, certainly, desirable configurations have not been identified yet. Moreover, their performances are ordinarily difficult to compare, especially owing to the fact that working ...

In this paper, we have continued doing a research project which had done previously. Three types of power plants include an Organic Rankine Cycle (ORC), a Dual-Fluid-Hybrid (DFH) and a single-fluid hybrid-fueled (HYB); were re-modeled. After model validation, thermodynamic studies and exergy analysis were extended for the defined cases using the first and second laws of thermodynamics. Then the...

Buildings contribute greatly to global energy use and consumption. The consumption of buildings is significant due the integration heating, ventilation, cooling systems. Evidently, utilization phase change materials (PCMs) in building design can adequately reduce air-conditioning costs by diminishing external heat gains losses. Moreover, adoption natural, eco-friendly, cost-effective materials,...

Integration of thermoeconomics and Life Cycle Analysis was carried out within the framework of an Environmental Management Information System. This combined approach identified where environmental loads were generated and tracked environmental loads throughout the system, allowing for a more precise understanding of operational activities. A trigeneration system was modeled, providing electrici...
