The purpose of this research is to investigate thermoeconomic optimization and exergy analysis of transcritical CO2 refrigeration cycle with an ejector. After modeling thermodynamic equations of elements and considering optimization parameters of emerging temperature of gas of cooler (Tgc) , emerging pressure of cooler's gas (Pgc) , and eva...

Industrial Ecology involves the transformation of industrial processes from linear to closed loop systems: matter and energy flows which were initially considered as wastes become now resources for existing or new processes. In this paper, Thermoeconomics, commonly used for the optimization and diagnosis of energy systems, is proposed as a tool for the characterization of Industrial Ecology. Th...

The organic Rankine cycle (ORC) has been widely studied to recover waste heat from internal combustion engines in commercial on-road vehicles. To achieve a cost-effective ORC, trade-off between factors such as costs, power outputs, back pressure, and weight needs be carefully worked out. However, the is still huge challenge engine recovery. In this study, thermoeconomic optimization study of ve...

This paper presents the design, evaluation, and optimization of an electricity generation system based on two-stage organic Rankine cycle (TS-ORC), which utilizes waste heat existing fluidized bed sewage sludge incineration (FBSSI) facility. The facility incinerates average 300 tons per day with a dry matter content 22%. After drying process, is burned in combustor, exhaust gas at temperature a...

This work develops a software to control and diagnose building thermal facilities based on thermoeconomics. It is tested with the data obtained from three blocks in Basque Country (northern Spain) aim of detecting potential energy saving points mitigating environmental impacts. Some obstacles, solved, are related insufficient number probes inherent errors sensors. Besides, new methodologies for...

Waste to fuel conversion has attracted prominence due higher demand, waste disposal issues, and environmental economic impact. Therefore, an alternative approach for addressing the issue of tire can be provided by using pyrolysis oil (TPO). The energy, exergy, thermoeconomic sustainability studies TPO-diesel blends were carried out in this study. analysis was compared with biodiesel-diesel blen...

Enhancing the sustainability and diversification of Iraq’s electricity system is a strategic objective. Achieving this goal depends critically on increasing use renewable energy sources (RESs). The significance developing solar-powered technologies becomes essential at point. Iraq, similar to other places with high average direct normal irradiation, good location for concentrated solar thermal ...

The aim of the paper is to identify consequence Constructal Principle in field Thermoeconomics (energy) production systems. This has been recently formulated as an extension Maximum Entropy Production and it used literature explain shape structure all kind flowing First, concept Thermoeconomic Environment defined consistently with consumption environmental resources residual emissions, which in...
