The mini-REFPROP program is a free sample version of the full REFPROP program(located at www.nist.gov/srd/refprop) and is meant for use as a teaching tool inthe introduction of thermodynamics to students. It contains a limited number ofpure fluids (water, CO2, R134a, nitrogen, oxygen, methane, propane, helium,hydrogen, and dodecane), along with air as a pseudo-pure fluid. It also allowsmixture calculations of a 50/50 molar mix of nitrogen and methane or of a 79/21molar mix of nitrogen and oxygen for teaching vapor-liquid equilibrium (VLE).Please note carefully that the 79/21 N2/O2 mixture is not meant for aircalculations, but as a teaching tool to study composition changes as the mixturepasses through the two phase. For actual air properties, please selectSubstance/Pseudo-Pure Fluid/Air when running the GUI.
Further answers can be found at GitHub: -issues/issues . Please use this site to post new questions as well so that all REFPROP users may learn from the correspondence. If you still need assistance, or have other matters that that you need to discuss, email refprop [at] nist.gov

Version 6.135 01/15/01A command to generate a high quality report in LaTeX and PDF (portable document interface) has been implemented in the file menu. To create and view PDF files, it is necessary to install a LaTeX compiler and Adobe Acrobat. Both of these applications are available at no cost. Instructions for downloading these applications and using the Create LaTeX/PDF Report command are provided in the online help. Property data for ideal gas C2H4 (ethylene) have been implemented.
7.1 When external portable containers are used for transfer, thecontainer must be evacuated at least 27 in of vacuum (75 mm Hgabsolute pressure) prior to transfer of the recycled refrigerant.External portable containers must meet DOT and UL standards. 2ff7e9595c
