Cogeneration and trigeneration systems have been broadly employed as part of the strategies oriented toward rational energy use. The assessment these must include simultaneous considerations costs, irreversibility, losses, their causes. This work presents a step-by-step thermoeconomic analysis microcogeneration unit, composed an internal combustion engine ammonia-water single-effect absorption ...

Abstract This article is based on the conceptual-thermodynamic design and exergoeconomic investigation of a new poly-generation system driven by biomass fuel (i.e. wood). In proposed energy system, Rankine power process, gasification desalination process multi-effect desalination, MED) water electrolyzer solid oxide cell, SOEC) are installed in hybrid form. Electric energy, fresh hydrogen gas u...

Excessive heat losses and water consumption in cooling units are significant constraints restricting the application circumstances performances for SCO2 Brayton cycle, exchange capacity precooler (PRC) is typically 1.5 times that of power generation. Therefore, this research offers a high-integrated combined power/cooling system which two waste exchangers (WHEs) rectifier (RET) used instead PRC...

Besides paying more attention to renewables, developing efficient multi-generation systems fed by currently available energy sources is another pathway sustainable development. Meanwhile, hydrogen production will play a key role in the green transition. The present work investigates gas-to-X system produce power, hydrogen, steam, and heat from thermodynamic economic points of view. proposed inc...

Integrated solar-assisted polygeneration systems have emerged as an effective and sustainable alternative for meeting thermal, power freshwater demands through decentralized generation. In this framework, study introduces a new design dynamic simulation approach to solar energy-driven system integrating gas steam turbine cycles, organic Rankine cycle (ORC), CO2 capture, humidification-dehumidif...

The use of air-source heat pumps (ASHP) is increasing to meet the energy needs residential buildings, and manufacturers equipment have permanently expanded range work improved efficiency in very adverse outdoor air conditions. However, time a wide different technologies, problem using ASHP, from techno-economic point view, constantly present. Exergetic exergoeconomic cost no longer provide suff...
