    Equation engineering solve



    Hi everybody,
    it's my first thread in this forum so I hope people answer it.
    I am developing some refrigeration projects with a software called Equation Engineering Solve.
    It is a very useful program which helps you to simulate the hole system. Its more interesting feature is that you have a refrigerants library with their properties. However, there are some refrigerants the software doesn't have, in particular I am interested in the R245fa.
    I guess that it may exist files with the properties of the refrigerant that you can insert into the EES's library to make it more complete but I am not sure if that it's true or you can not modifiy the library of the software.
    Could someone help me with that? Does someone have the R245fa file properties? and how can I insert it in the EES's library?
    Thank you guys

    Carlos

    Re: Equation engineering solve

    I believe this was added to the properties file in a previous release. You can find out which version at the EES web site.

    You must be working on a an organic rankine cycle.

    Hi Iceman,
    thanks for the information but I don't understan what do you mean with previous release? Is it a previous version of the EES.
    Whichi is the EES website?
    Thank you again.
    Of course, I am working on an ORC, xD

    You can find the specific release version here: http://fchart.com/ees/newfeatures.htm

    If your version does not have the refrigerant you are looking for you will need to update your software.

    The update information is here: http://fchart.com/ees/update.shtml

    NEVOT,

    Best of luck with your project. I think those ORC systems are fascinating.

    Re: Equation engineering solve

    me too.
    The problem is that industries do not rely fully on them but I think they are a very good optin to rise the efficiency.
    Isn't it incredible to use waste heat or combustion gases at 150-200ºC??
    By the way, where do you live Iceman?? Is there a lot of ORC developed projects?? Industries??

    Re: Equation engineering solve

    The location of RE members is shown on the top right corner of each post, if they choose to list it.

    I have heard of several ORC projects here in the US, but do not know where their specific locations are, or what the details contain. My interest in these systems is for application to low temperature heat recovery and... They are refrigeration systems that work in reverse, which I find very interesting.
