NH3/H2O Absorption cycle on log(p)-h diagram

Dear Members,

I am trying to draw an ammonia/water absorption cycle on a log(P)-h diagram. Somewhere I have seen that Coolpack can use material properties from NIST's RefProp, with which I can draw a diagram of mixtures. Do you think combining the capabilities of the two programs is the way to draw the required diagram? If yes, where do I find information on how to combine Coolpack and RefProp? If no, I'll appreciate any suggestions.

Thanks,
Mati Zaidman
