EASY: Exergetic Analysis of SYstems interactive computer code for refrigerants thermodynamic properties evaluation and exergetic analysis of vapor compression systems

A soft~are packcage for both the thermodynamic properties computa~ic~ and tne analysis of usual vapor compression plant schemes is an usefu: tool for air conditioning and refrigeration researchers and manifacture>s. At ~he Present time, it could sUPPlY an important contribution to search for CFCs substitutes; in fact, comparisons between two or more ~o•king fluids could be accomolished more easilY. A code carried out by the authors is presented by means of some demonstrative diagrams re~erring to a comparison between the "ozone killer" R12 and its substitute R134a. The Rl34a exergy-enthalpy chart is provided too.
