摘要：
A software package for both the computation of thermodynamic properties and the analysis of the usual vapour compression plant schemes is a useful tool for air conditioning and refrigeration researchers and manufacturers. At present, it could make an important contribution to the search for CFC substitutes; in fact, comparisons between two or more working fluids could be accomplished more easily. A program code carried out by the authors is presented by means or some demonstrative diagrams referring to a comparison between the 'ozone killer' R12 and its substitute R134a. An R134a exergy-enthalpy chart is also provided.
