NIST REFPROP: Thermodynamic Properties for 105 Pure Fluids and Mixtures

NIST SRD 23 contains thermodynamic and transport property data for 105 pure fluids, including environmentally acceptable HFCs, traditional CFCs, and natural refrigerants like ammonia. The database allows for mixtures of up to 20 components and provides Fortran subroutines, data files, and a sample Excel spreadsheet for integration. Version 9.1 has replaced the older NIST 12 and 14 databases.

Use Cases

• Calculate refrigerant properties for HVAC system design based on the database's fluid library.
• Model thermodynamic cycles for power generation based on mixture capabilities for up to 20 components.
• Integrate property calculations into custom simulation software using the provided Fortran subroutines.
• Perform property lookups and calculations within Excel spreadsheets using the demonstrated DLL link.

Strengths

• Includes data for 105 pure fluids, providing a wide selection for analysis.
• Supports complex mixtures of up to 20 different components.
• Provides source code (Fortran subroutines) for direct integration into user applications.

Limitations

• Row count and specific column definitions are unknown, limiting suitability assessment.
• Last update date is unknown; freshness unverified.
• License is closed, which may restrict redistribution or commercial use.
