Exergy Analysis of a Ground-Coupled Heat Pump Heating System with Different Terminals

open access: yesEntropy, 2015
In order to evaluate and improve the performance of a ground-coupled heat pump (GCHP) heating system with radiant floors as terminals, an exergy analysis based on test results is performed in this study.

Exergy and cumulative exergy use analysis

open access: yes, 2016
Exergy is a thermodynamic metric that represents the amount of useful energy one can obtain out of an object in a given reference environment. The exergy concept is used in several applications: from the analysis of industrial processes to economic, sustainability and ecosystem analysis.

The Exergy of Lift, and Aircraft Exergy Flow Diagrams

open access: yesAdvanced Energy Systems, 2001
Abstract Aside from incidental, auxiliary loads, in level flight the principal load on the aircraft propulsion engine is the power required to provide the continuous lift. To construct an exergy flow diagram for an aircraft — for example, for the purpose of exergy costing — an expression is needed for the exergy delivered to (and by) the

Exergy Efficiency of Closed and Unsteady-Flow Systems

open access: yesEntropy
Exergy efficiency is viewed as the degree of approaching reversible operation, with a value of 100 percent for a reversible process characterized by zero entropy generation or equivalently zero exergy destruction since Xdestroyed = T0Sgen.
