NIST Reference Fluid Thermodynamic and Transport Properties Database (REFPROP)

REFPROP Overview

REFPROP is an abbreviation for REFerence fluid PROPerties (REFerence fluid PROPerties). 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. These properties can be displayed in tables and graphs through a graphical user interface; they are also accessible through spreadsheets or user-written applications that access the REFPROP dll library.
