I would like to model a Solid Desicant not as a preconditioner but to
simulate the following:

1. Precool outside air with a DX coil to a saturated condition,

2. Run that saturated air through the Solid Desiccant (therefore
running the Desicant at its most efficient point starting from a
saturated condition), and

3. Finally mixing that air with return air and then running that
through a Cooling Coil served by a Chiller before supplying to the
space.

Regards,

Ian Doebber
