Abstract

The exergy-enthalpy and temperature-exergy diagrams have been generated in the range 0.1-10 MPa and from the triple point to 500 K. These diagrams on the International Temperature Scale (ITS-90) have been generated using a calculation scheme proposed by Jacobsen et al. A computer program is developed for calculating the thermodynamic properties of nitrogen, including exergy as a property, from the triple point to 800 K at pressures up to 30 MPa. These exergy based thermodynamic property charts can be useful in the energy efficiency analyses of cryorefrigeration cycles involving nitrogen as a working medium. A sample analysis is included.
