    Newbie Question - SH Pressure



    Hi, I am new in the field of refridgeration (domestic) and battling a bit with the fundamentals. So here is my first question to the forum: why does the pressure not rise in an evaporator after all the refidgerant has evaporated and becomes superheated? more heat applied to a gas causes a pressure rise for a set volume was my understanding?
    Please explain in '101' language.
    Thanks, Michael

    When fully evaporated , only temperature will rise & gas will become superheated in a fixed volume ( evaporator)

    OK, now I am missing something...pressure is proportional to temperature for a fixed space (Boyles Law)?
