CoolProp

CoolProp is an open-source library dedicated to fluid thermodynamic and transport properties, serving as a cross-platform alternative to NIST REFPROP. It provides accurate, peer-reviewed data for a wide range of fluids, including refrigerants, and supports integration with popular programming environments. Researchers and developers can leverage its capabilities for simulations, modeling, and design applications without proprietary constraints. CoolProp fosters innovation by making advanced fluid analysis tools freely available and easy to implement.
