@mayersre Do you have any ideas for things we might want to add to the docs currently at http://www.coolprop.dreamhosters.com/binaries/sphinx/coolprop/REFPROP.html#refprop ? I think you are the most experienced CoolProp+REFPROP user

[mayersre]

sorry for the delay, but I move my home office currently ...

I like the documents from the link above and I like the alternative REFPROP path, it will help a lot when
experimenting with different binary pairs or using modern blends from dupont in calculation as it allows the usage of the duprex hmx.bnc file . I like the documentation on the low level interface even better ... I will try it in winter with my diagrams and some new nomographs and look what performance improvement can be gained.

Ok, glad you like them. If you have any ideas for things to put there, let
me know.

I run TestCoolprop.py code below

import CoolProp
print(CoolProp.__version__)
print(CoolProp.__gitrevision__)

import json, CoolProp.CoolProp as CP

jj = json.loads(CP.get_config_as_json_string())
jj['ALTERNATIVE_REFPROP_PATH'] = '/home/mayers/git/kformaug/extern/rp_nist/'
jj = CP.set_config_as_json_string(json.dumps(jj))

ref='REFPROP::R449A.MIX'
press=101325
bub_nist=CP.PropsSI('T','P',press,'Q',0,ref)-273.15
dew_nist=CP.PropsSI('T','P',press,'Q',1,ref)-273.15
print('{} Bubble point : {} Dew point {} at {} Pa.'.format(ref,bub_nist,dew_nist,press))

Output is fine

5.1.1dev
ccc012c31a7c1505f5399acfa5ab85f24f41fd8b
REFPROP::R449A.MIX Bubble point : -44.04775623435387 Dew point -38.05712164462065 at 101325 Pa.

or

5.1.2dev
851c961cd6e584c452489fd3ae668e6f03ef1da6
REFPROP::R449A.MIX Bubble point : -44.04775623435387 Dew point -38.05712164462065 at 101325 Pa.

But it does not take refprop from '/home/mayers/git/kformaug/extern/rp_nist/'

if I strace it, the output does not even contain 'nist'

strace -o x.out python TestCoolprop.py
grep nist x.out > nothing

Thanks for the comment. I am not sure how the path is handled on Linux, I think we only support Windows for now...

@mayersre , I edited your post and added fenced code blocks to make the source code easier to read.

Actually, I wrote the docs, but they are currently ahead of the code. I'll
fix the code soon I hope.

Can you try again? I updated the code. If it works, we can close the issue.

[mayersre]

That works nicely now on Linux. I cloned the repo, built coolprop by instruction from the website, installed it into my virtualenv (no sudo neccessary), re-ran the commands for refprop access from django --> success.
Coolprop Version : 5.1.2dev
Gitrevision : 08e2761

Switch ALTERNATIVE_REFPROP_PATH from rp_nist to rp_honeywell to rp_dupont --> success

Thanks 👍

Have you tried to use the path to the HMX.BNC file? Does that work for you? I think it should. For now, I am going to close this issue... Any further problems, please re-open. Any other recommendations for the docs, I'm game as well.
