    ASHRAE Fundamentals Handbook is a good place to start. The major refrigerant manufacturers will also provide you with these charts.

    ... has some refrigerants listed. You can do a web search and find others if you're interested in on-line info.

    Nikki, Try this site.

    http://www.solvay-fluor.com/produkte...me_kaelte.html

    If you follow the links, it contains info on all the refrigerants you mention. The ph chart is also referred to as a Mollier diagram. You will need adobe reader to see it.
    The resolution is not good on the screen and it's a lengthy down load.
    Your best bet is to ask one of the manufacturers for a CD ROM, or a paper version, which is usually A3 size. SOLVAY are very good for this, their technical info is excellent. They used to give them away free.
    Good Luck
