    Looking for R507 Pressure/Enthalpy Chart

    I've been trying to get my hands on an R507 Pressure/Enthalpy Chart (Molier Chart), but have only been able to find one in SI units, which would be great if i wanted to convert every single point on the graph. If anyone has a decent quality Chart they can post that would be awesome. I spent a few hours going through my school books, but we only did charts on R22 and R717.

    Cheers

    My searches have come up with nothing as well.

    You might try contacting DuPont or Honeywell (Genetron) tech services and request a copy.

    Alternately, DuPont's Duprex software will generate a cycle diagram on a Mollier chart.

    Lots of good information there, but they don't provide Mollier diagrams.

    Ice, a while back I had my company's engineering department e-mail me the 2005 ASHRAE Handbook chapter 20 "THERMOPHYSICAL PROPERTIES OF REFRIGERANTS" that has a good amount of Mollier diagrams.

    want it for the educational forms?

    Thanks. We would love to have material like that...

    ...but due to Copyright issues, we cannot post them in the Educational Forums.

    We'd still like to have that on file...just in case the rules change one day.

    Thanks for posting this pdf!. I'm studying cascading refigeration systems and only had access to 134a, 404a and 410a.
