    Formula

    Unfortunately, I don't have the formula, or know  if there is one.  Try the ASHRAE or ACCA website, they, if anyone, they would have it.  Sorry I couldn't help.

    psyhrometrics chart

    Plot the existing wb, db, rh, on a psyhrometrics chart and compare to the new wb, db, and rh.  This will tell you the new conditioned air values.



    Thanks,  MN Wayne
