On Intrinsic Exergy Efficiency and Heat Pumps

Chemical Engineering Research and Design, 2000
Exergy analysis provides an assessment of the degree of thermodynamic perfection of a process. Several exergy efficiency definitions have been proposed among which is the intrinsic efficiency which is based on the concept of transiting exergy. This method of analysis has been applied to absorption heat pumps and the results are presented.

Primary exergy efficiency—Effect of system efficiency environment to benefits of exergy savings

Energy and Buildings, 2016
Abstract Improving energetic performance is a key factor in making societies more sustainable. One way to analyze energetic performance is to use methods based on the second law of thermodynamics. Exergy analysis is such a method. With exergy analysis thermodynamic losses of the studied system can be found.

Efficiencies of exergy transductions

Applied Energy, 1980
Abstract Exergy is conserved in thermodynamically reversible heat engines and heat pumps. Using a reversible heat engine to stimulate a reversible heat pump, available power and exergy may be exchanged, the total amount of exergy being conserved. For such a combined system, either more heat may be released at a lower temperature or energy may be ...

Exergy efficiency and conversion of chemical reactions

Energy Conversion and Management, 1998
An exergy analysis of the ammonia oxidation in nitrous oxide has been performed using alternatively the conventional second law efficiency and the more recently proposed intrinsic exergy efficiency. It is shown that the second law efficiency does not account for the conversion effect on the overall performance of a chemical system while the intrinsic ...
