Hi,

I am working on a project that utilizes a unique partial return air design (in addition to the traditionally forced air return).

The exterior walls locations have return air slots that are located between the inside face of glazing and the window blind (about 6-10 inches gap) allowing for extraction of a percentage heated air between blind and glass to be removed before mixing with air in the occupied area.

Does anyone know how to model this type of design and provide me with some assistance.

Thanks for the help.
