Abstract

The difinition of exchargy is given and its significance as the true content of effective energy associated with a given system in a given environment is considered. Its graphical representation on a P-V diagram is shown. Curves are given showing the dependence of exergy on temperature and pressure, and their significance in the design of energy storage system is considered. The thermodynamical efficiency of room heating systems is considered as an application.
