ORC systems use organic fluids (like R245fa or R1233zd) to generate power from low-temperature heat sources (solar, geothermal, industrial waste heat). REFPROP 9.1 provides the precise superheated vapor properties and two-phase expansion behavior needed to optimize turbine inlet conditions.
NIST no longer officially sells or supports version 9.1. Current sales are for version 11.0 or newer. However, existing 9.1 licenses continue to work indefinitely. Some legacy DVDs and installer files circulate within institutions under site licenses.
