REFPROP is based on the most accurate pure fluid and mixture models currently available. The equations are generally valid over the entire vapor and liquid regions of the fluid, including supercritical states the upper temperature limit is usually near the point of decomposition of the fluid, and the upper pressure (or density) limit is defined by the melting line of the substance. Their high accuracy is obtained through many coefficients in the equations, and thus the calculation speed will be slower than other equations such as the Peng-Robinson cubic equations. These equations are the most accurate equations available worldwide. The program uses equations for the thermodynamic and transport properties to calculate the state points of the fluid or mixture. The REFPROP "database" is actually a program and does not contain any experimental information, aside from the critical and triple points of the pure fluids. REFPROP is a Program, not a Database Containing Measurements. This program, developed by the National Institute of Standards and Technology (NIST), calculates the thermodynamic and transport properties of industrially important fluids and their mixtures. In the thermodynamic module also FLUIDCAL is used by CONVAL ®
