The Refprop Database for the Thermophysical Properties of Refrigerants



Mark O. McLinden, Eric W. Lemmon, Marcia L. Huber


Property databases are widely used for the design and analysis of refrigeration systems. Version 7 of the NIST REFPROP Reference Fluid Thermodynamic and Transport Properties) database is described. Compared with previous versions, the database includes additional fluids and mixtures (including ammonia/water mixtures), improved property models, additional properties, increased calculational speed, an enhanced user interface, and support for using the property routines with other applications. This program is based on the most accurate pure fluid and mixture equations of state and transport property models currently available, and these sources are internally documented in the database. The models are implemented in a suite of subroutines written in standard Fortran which may be used independently of the user interface. This database has become the de facto standard for refrigerant properties.
