[Equest-users] PTAC units and ventilation air

[Aleka Pappas]

Hello,
I'm trying to figure out if I'm modeling a PTAC unit's OA intake
accurately.  Does anyone know if the OA cfm listed for the unit is fixed, or
if this rate can be lowered?  For example, a McQuay PTAC unit has 50 cfm OA
listed in the manufacturer's data.  Is this rate brought in any time the
unit cycles on, or can it be adjusted down?  (The design OA rate is about 30
cfm for the hotel room, so I'd like to be able to adjust it down.)

Thanks for your help,
Aleka
