    Talking Refrigerant R502



    Dear All

    Hi, good day to everybody.
    I m studying the refrigeration system.

    I had extracted the p-h chart for R502 from the coolpack program.

    Could any one confirm that the chart is correct, as i found one in my book is different from this.

    thanks for your help.

    What's exactly the difference?
    Are the units the same?
    It's better to keep your mouth shut and give the impression that you're stupid than to open it and remove all doubt.

    The difference may be due to the zero enthalpy point on the diagrams. This does not make any difference in the calculations as long as you only use one diagram.

    Do not mix values from one diagram to another as you will end up with incorrect answers.

    Hi Kkchiew,

    You should sent the jpg from your book not from CoolPack, becuse all of us have that program but that book only you have

    How we can check the difference

    Best regards,

    Josip
