Unable to use REFPROP material library

Hello,

I am trying to use MATLAB code from database of REFPROP ("refrigerant property" a software for calculating refrigeration system performance) to evaluate my system performance.

here is the link which says about how to use refprop matlab codes: http://www.boulder.nist.gov/div838/theory/refprop/Frequently_asked_questions.htm

I did this for one of the PC in the lab there it is working fine, but in my system it is not working.

i am getting the following error message

??? Error using ==> refpropm at 264
[SETUP error 101] error in opening
file for component #  1; filename =
(C:\Program Files
(x86)\REFPROP\fluids\ammonia.fld|
).

I am using the same version of Matlab in both the systems. Please tell me what might have gone wrong...

Thanks

Hi Shishir, I faced a similar problem; the only problem is you don't have your fluid library in the refprop folder, go to following link, install refprop mini>go to installation directory>copy fluid folder from library>paste it in your refprop dir>You may uninstall refprop.exe afterwards http://www.boulder.nist.gov/div838/theory/refprop/MINIREF/MINIREF.HTM

Hi, excuse me.

thanks for provoding the solution aoove.

I am now confronting the same problem, and also tried the approach mentioned above, but it didn't work, cause I am trying to obtain the properties of air.

could you please help give some advice? thanks.

Hi Ting

I also had the same problem with accessing Air properties.

However, the solution was so simple!

All you have to do is go to the directory where your file is located and simply change the .PPF file extention to .FLD!
