Humidity control for individual room

[seanhkim]

I have a case that a single duct VAV system serves several rooms, which means reheat coil is inside of the terminal box.

One of rooms in the zone has high humidity due to internal process. But other rooms are OK. Without dedicated dehumidifier, how can I reduce the humidity of this room?

First I decrease the set point temperature of cooling coil and drain out the extra moisture and reheat the air using reheater in the terminal box. My question is that every room in the zone gets the drier air which they don't necessarily need.

Is there anyway to decrease the humidity of that specific room without any dehumidifier?

Thank you in advance for your answer
Sean

Separate cooling coil - duct mounted.

Exhaust the humid air using point source exhaust duct connected/discharging into the general exhaust, or use an individual exhaust fan to extract the humid air from the "thing" that is giving off the humidity and dump the air out somewhere safe. Get rid of the moisture before it infuses in the ambient air in that room. Increase the supply air flow to that room slightly to provide make-up and keep the room at a slight negative air pressure relative to the rest of the rooms (tough with a VAV system- but you may have to use a VAV exhaust scheme).
