Low exergy modelling and performance analysis of greenhouses coupled to closed earth-to-air heat exchangers (EAHEs)
(ELSEVIER SCIENCE SA, 2013)
The present study deals with modelling, analyzing and assessing the performance of greenhouse heating systems with earth-pipe-air heat exchangers (EAHEs) in closed loop mode. In this regard, an EAHE system is considered ...
Energetic and exergetic analyses of T56 turboprop engine
(PERGAMON-ELSEVIER SCIENCE LTD, 2013)
This study presents the results of energetic and exergetic analyses of T56 turboprop engine at various power loading operation modes (75%, 100%, Military and Takeoff). The energetic and exergetic performance evaluations ...
Splitting the exergy destruction into avoidable and unavoidable parts of a gas engine heat pump (GEHP) for food drying processes based on experimental values
(PERGAMON-ELSEVIER SCIENCE LTD, 2013)
Some limitations in a conventional exergy analysis may be significantly reduced through an advanced exergy analysis. In this regard, the latter is a very useful tool to assess the real potential for improving a system ...
Experimental exergoeconomic assessment of a desiccant cooling system
(PERGAMON-ELSEVIER SCIENCE LTD, 2013)
Desiccant cooling has become a well established technology in most parts of the world, especially recently in Turkey. The increased growth of the technology was caused by the contribution of refrigerants used in conventional ...
Energetic and exergetic aspects of solar air heating (solar collector) systems
(PERGAMON-ELSEVIER SCIENCE LTD, 2013)
Solar air heating (solar collector) is a renewable heating technology and provides heat using solar energy. With fuel costs and other factors, solar air heaters (SAL-Is) are getting more attention. The energetic and exergetic ...
Performance assessment of hydrogen production from a solar-assisted biomass gasification system
(PERGAMON-ELSEVIER SCIENCE LTD, 2013)
In this study, we investigate a solar-assisted biomass gasification system for hydrogen production and assess its performance thermodynamically using actual literature data. We also analyze the entire system both energetically ...
Exergoeconomic and environmental impact analyses of a renewable energy based hydrogen production system
(PERGAMON-ELSEVIER SCIENCE LTD, 2013)
In this study, exergoeconomic and environmental impact analyses, through energy, exergy, and sustainability assessment methods, are performed to investigate a hybrid version renewable energy (including wind and solar) based ...
Advanced Exergy Analysis of a Heat Pump Drying System Used in Food Drying
(TAYLOR & FRANCIS INC, 2013)
Exergy analysis has been used as a powerful tool to study and optimize various types of energy systems. However, the methodology of splitting the exergy destructions (the so-called advanced exergy analysis) allows for a ...
Future Aspects of Geothermal Energy in Saudi Arabia
(TAYLOR & FRANCIS INC, 2013)
Geothermal energy seems to be a clean, proven, and reliable resource for supplying the needs of a sustainable society and helping to improve the global environment. Although the studies on geothermal resources exploration ...
Energy and exergy analyses of porous baffles inserted solar air heaters for building applications
(ELSEVIER SCIENCE SA, 2013)
This study deals with performance assessment of porous baffles inserted solar air heaters (SAHs) using energy and exergy analysis methods. The porous baffles (PBs) with different thicknesses are used as passive element ...
