    TXV

    Are you talking theoretically? Or are you on a service call w/ a system that has a problem because the TXV is  r22 and the comp is r134a  and the Walk-In is warm  because the TXV is not feeding enough freon?!

    capacity modifiers

    1. Differential pressure across the TXV.

    2. Subcooling of the liquid.

    3. Superheat at the coil outlet.0

    This sounds like a test......:-)

    I'll say Orifice size in valve, Delta" P" between hi and lo side and The temp and state of the liquid entering the valve...........



    I took a shot.  It's been a while since theory racked my brain......



    Peace
