Hello everyone,


We have a pipe through which humid air is flowing 
We want to dehumify this in a dehumifier. This equipment has a higher inlet area for air 

We have small space and we build this double 90 degree ducting to connect the pipe and the dehumidier (see link with picture). We didn't install anything yet. I am concerned now that the air will not flow through the entire inlet area of the dehumidifier and the perfromance will drop considerably.

Will the air flow like in the left side (A) or the right side ( B)? Are there any modifications that can be made to make it flow more like ( B)?




Thank you.

How air will distrubute over the inlet of the dehumidifier will depend on the pressure drop of the dehumidifier.


If you are concerned you could use socalled vaned elbows, like for example in these sketches:
