Advanced thermodynamic analysis on exergy flow grafs

2017
У статті запропоновано загальний підхід для термодинамічної аналізу систем довільної структури. Метод заснований на побудові і аналізі нового виду ексергією-топологічної моделі – ексергетичному потоковому графі і дозволив підвищити ефективність енерго-інтенсивних систем. Було показано, що процеси, які відбуваються в складних енерго-інтенсивних системах,

Advanced Exergy and Exergoenvironmental Analysis of an Integrated Power and Refrigeration System

Journal of Testing and Evaluation
ABSTRACT This study looks at the performance of a system that combines an organic Rankine cycle (ORC) and an ejector refrigeration system (ERC) using advanced exergy and exergoenvironmental-based methods to find ways to make it better and to see how the different parts of the system work together.

Exergy Linked to Environmental Impacts: Advanced Exergoenvironmental Analysis of an Advanced Zero Emission Plant

Volume 4: Energy Systems Analysis, Thermodynamics and Sustainability; Combustion Science and Engineering; Nanoengineering for Energy, Parts A and B, 2011
Exergy-based analyses are useful means for the evaluation and improvement of energy conversion systems. A life cycle assessment (LCA) is coupled with an exergetic analysis in an exergo-environmental analysis. An advanced exergo-environmental analysis quantifies the environmental impacts estimated in the LCA into avoidable/unavoidable parts and into ...

Advanced Exergy Analysis of a Compression–Absorption Cascade Refrigeration System

Journal of Energy Resources Technology, 2018
This work presents a theoretical thermodynamic study of a compression–absorption cascade refrigeration system using R134a and a lithium bromide–water solution as working fluids. First and second law of thermodynamics analyses were carried out in order to develop an advanced exergetic analysis, by splitting the total irreversibility and that of every ...

Energy and exergy analysis of advanced cycles for solar cooling

2008
In conventional desiccant and evaporative air-conditioning systems (DEC) employing solid sorptive materials, the regeneration stage is powered by thermal energy. The use of solar energy to assist the regeneration process is obviously a good solution to reduce the primary energy consumption.

Advanced exergy analysis applied to a single-stage heat transformer

Applied Thermal Engineering, 2017
Abstract This study presents an advanced exergy analysis of a single-state absorption heat transformer operating with a lithium bromide water solution. A traditional exergy analysis was also conducted to identify the components with the highest contribution to the exergy destruction, and an advanced exergy approach was developed to estimate a ...

Advanced Exergy Analysis for a Solar Double Stage Absorption Chiller

2012
Solar driven absorption chiller technology as an alternative mechanism for cooling has been the focus of tremendous recent interest due to its potential advantages for energy conservation and the environment benefits. However, the comparatively lower coefficient of performance (COP) of these systems compared to the COP of the electric chillers has ...
