[Equest-users] Modeling a Solid Desiccant after a DX Coil

[Brian Fountain]

I haven't tried this but I think if you put the desiccant &  chilled 
water coil on your main, return air system and then used the OA-FROM-SYS 
keyword to take air from a 100% OA system with a DX coil --  might best 
model your system.  The challenge is controlling the DX OA system -- 
perhaps to a fixed SAT setpoint -- there is no wetbulb control in 
DOE-2.2 that I know of.
