    Neil, if you go to this site http://www.et.dtu.dk/Index.html there is a program call coolpack. Its very good you can plot PH charts and read of enthalpy, sorry if I too late.

    I will check out coolpack too... just loaded it up. i hope it is freeware like the site says? but whats this download here if registered thing?

    I would also love to know where to get enthalpy pressure charts for all refrigerants, as so far my hours searching has proved fruitless...

    I have had a lot of luck from DuPonts sight, but it takes some surfing around.

    Hi
    coolpack has within a separate program called Ref Utilities.
    This contains most of the PH diagrams you will ever need.
    Regards. Andy.

    Thanks everyone, I have tried coolpack but it still doesn't deal with good old isceon 49 (R413a). But it is really useful software.
    If you can't see it, it can't hurt you.

    Neil,
    try www.isceon-refrigerants.com
    and down load or request on disc IScool, this will allow you to generate ph diagrams for the various isceon refrigerants.
    Regards. Andy
