Hi all. I am studying on a project which is about constituting an online pressure-enthalpy diagram. For this purpose, I mesaured pressure and temperature and, use these data to find the enthalpy of the refrigerant. To constitute a pressure-enthalpy diagram by using state equations seems though for now. Could I use refprop pressure-enthalpy diagrams easily in labview? I do not have refprop yet. I want to be sure that whether it is useful for me or not before buying it. Could someone inform me on this issue? Thanks in advance.

Hi there,
As Refprop is not a National Instruments product, I cannot find any resources on our end that might help answer your question. There is a thread I have linked below that may be helpful, but I would suggest contacting NIST directly.

Best,
The thread you mentioned does not give the exact answer, unfortunately. So yesterday, I asked the same question to Dr. Lemmon from NIST. I am posting his answer below:
"Using the P-H diagrams in Labview is not possible with our current set up."
Thank you very much.
