Thermodynamics is air ducts, dew point

  1. Jun 18, 2012 #1
    Can anyone confirm if the flow of air inside an air conditioning duct, when cooled, behaves as constant volume as compared to constant pressure? I am trying to determine the dew point of the flow and, depending of how it behaves inside the duct, this value will depend on if it is at constant voulume or constant pressure. I think it is at constant volume. Please confirm.

    The duct is open on both ends. There is going to be a small pressure differential due to the fan, required to move the air, but it's going to be almost insignificant. To a good approximation, you can assume constant pressure.
