What is CoolProp?

CoolProp is a C++ library that implements:

• :ref:`Pure and pseudo-pure fluid equations of state and transport properties for 114 components <list_of_fluids>`
• :ref:`Mixture properties using high-accuracy Helmholtz energy formulations (or cubic EOS) <mixtures>`
• :ref:`Correlations of properties of incompressible fluids and brines <Pure>`
• :ref:`Highest accuracy psychrometric routines <Humid-Air>`

Environments Supported

Programming Languages:

• Fully-featured wrappers: :ref:`Python (2.x, 3.x) <Python>` , :sfdownloads:`Modelica <Modelica>`, :ref:`Octave <Octave>`, :ref:`C# <Csharp>`, :ref:`MathCAD <MathCAD>`, :ref:`Java <Java>`, :ref:`MATLAB <MATLAB>`
• High-level interface only: :ref:`Labview <Labview>`, :ref:`EES <EES>`, :ref:`Microsoft Excel <Excel>`, :ref:`LibreOffice <LibreOffice>`, :ref:`Javascript <Javascript>`, :ref:`PHP <PHP>`, :ref:`FORTRAN <FORTRAN>`, :ref:`Maple <Maple>`, :ref:`Mathematica <Mathematica>`, :ref:`Scilab <Scilab>`, VB.net, :ref:`Delphi & Lazarus <Delphi>`, :ref:`Julia <Julia>`

Architectures:

• 32-bit/64-bit
• Windows, Linux, OSX, Raspberry PI, VxWorks Compact Rio, etc. (if you can compile C++ on it, CoolProp will run)

High-Level Interface Example

In most languages, the code to calculate density D of Nitrogen at a temperature T of 298 K and a pressure P of 101325 Pa is something like:

rho = PropsSI('D', 'T', 298.15, 'P', 101325, 'Nitrogen')

See more examples of PropsSI usage at :ref:`High-Level interface <high_level_api>` or :ref:`Examples <examples>`
