    Lightbulb P/T Charts in PSI/kPa/Bar

    I got really tired of always looking for p/t charts for various refrigerants so I decided to make my own. I used coolpack to find the different critical temp/pressure relationships and plotted them out on Open Office spreadsheet. It is not as accurate as I would like because Coolpack uses a quadratic formula to estimate temps on a curve, rather than actual temperatures but its is still really close. Also, I have made it in Excel format as well, but some of the graphs are messed up, because, well, its excel.

    Open Office
    home.student.utwente.nl/r.makkink/PT_Chart.ods
    Mirror
    http://files-upload.com/files/521403/PT%20Chart.ods

    Excel
    home.student.utwente.nl/r.makkink/PT_Chart_ver._0.6_beta.xls
    Mirror
    http://files-upload.com/files/521398...0.6%20beta.xls

    Both Files

    Again, works best with open Office. If you dont have it, its a free MS Office replacement. www.OpenOffice.org But if you insist on using excel its there too

    Let me know you opinions on it. Tell me whats wrong with. What should be added. What should be left off. What you like. What you think is ridiculous.

    Thanks

    If you are having trouble downloading, PM me so I can fix it.

    Is it OK if I rehost it on aMule and Gnutella?

    the pressure range of the r1150 diagramm is to tight. you start at 7 bar, but you should go down to 0.1 bar or 0.5 (absolute).

    same for r774 and r23

    kPa diagrams are not important because its just the [bar] value times 100. MPa is also more often used in HVAC than kPa. I think Pa in deep vacuums and MPa in normal refrigeration.

    but i like the nice overview!

    these amounts were based on the coolpack equations. if you have actual values for r23, r774 and r1150 i would love to update them. And for vacuum, i was thinking of using mmHg instead of Pa.

    @star882

    yes you can rehost there, but you might want to wait until I revise and get a moe finished product.

    I have updated the spreadsheets. Still in Bar/kPa/psi.

    -Updated R23, R744, R1150
    -Got Rid of Some Bugs
    -Edited some Graphs to correct formatting issues

    The links have been fixed for now.

    I now need a new RELIABLE server for hosting these files.

    @ JACK and STAR882 - If you want to host these files, lease do, and PM links to me so I can post up top
