Hello everyone, i have some question, may you guys help me?
so, i was trying to get the value of entalphy and entrophy using REFPROP (for my multiobjective optimization), here the code:
t5 = 6+273; %in kelvin
p5 = refpropm('P','T',t5,'Q',1,'r407c.mix');
h5 = refpropm('H','T',t5,'P',p5,'r407c.mix');
s5 = refpropm('S','T',t5,'P',p5,'r407c.mix');
but i got some error, said that;
Error using refpropm (line 267)
[SETUP error 101] error in opening file for component #-22; filename = (C:\Program Files
(x86)\REFPROP\fluids\c12.fld).
i dont why the matlab trying to open fluid's folder, i mean i was trying with mixture, but why it's not opening the mixture folder?
if i used the refrigerant type : R134A (this is a pure fluid not mixture like R407C) it's working but when i used mixture it's not working.
thank you.

Do you have a refprop license ?
