A Systematic Approach to Exergy Efficiency of Steady-Flow Systems

Entropy
Exergy efficiency is a measure of thermodynamic perfection. A device that operates reversibly has an exergy efficiency of 100 percent and is said to be thermodynamically perfect.

Comparison of buildings’ energy consumption by means of exergy method

, 2007
In this paper a new method starting from the LowEX tool, previously developed in the IEA ECBCS Annex 37 framework, in described. Following the energy conservation principle, the total consumed exergy is obtained summing the exergy exchanged in the ...

Extended Exergy Analysis of the Nova Scotian Economy 2006

, 2011
Human societies may be modeled as very large complex systems involving multiple flows of energy and materials between different sectors. Traditional exergy analysis methods are inadequate for the analysis of such systems because they do not take non ...

Using Exergy Analysis Methodology to Assess the Heating Efficiency of an Electric Heat Pump [PDF]

, 2006
The authors, using exergy analysis methodology, propose that it should consider not only the COP (coefficient of Performance) value of the electric power heat pump set (EPHPS/or HP set), but also the exergy loss at the heating exchanger of the HP set to ...
