NIST offers heavily discounted student and institutional licensing for universities. Check with your department to see if a site license is already available. However, the full version (including version 9

For many engineers, REFPROP 9.1 was the reliable workhorse of the early 2010s. It provided critical data for refrigerants, hydrocarbons, and cryogens. Its accuracy made it the gold standard against which other commercial simulators, such as Aspen HYSYS or COOLPROP, were often validated. The specific demand for version 9.1, even years after its successor was released, stems from its stability and the familiarity long-time users have with its specific input/output structures. However, it is crucial to acknowledge its limitations; version 9.1 lacks the expanded fluid lists and modern interface features of the current version (version 10 and beyond), and it may not include the most recent refrigerant blends required for modern environmental compliance.
