Ventilation requirements for fermentation room
I am currently working on ventilation requirements for my new brewery. One area I'm unsure of is ventilation for my fermentation room. The basic setup is something like this: 4 - 8 bbl plastic conicals and 2 - 3.5 bbl plastic conicals in a temperature controlled room, approximately 12'x20'. I'll ferment around 68 degrees and rack to a jacketed brite tank (outside the room) for clearing and carbonating.
There weren't and red flags for any HVAC guys I've talked to about doing this with a basic A/C setup. Unfortunately, I hadn't considered the requirements for venting CO2 safely while maintaining temps. Should this be a simple vent at the floor? How much volume would I need to push? Can I vent the CO2 from the fv's directly out of the room? Am I even asking the right questions!? What have you guys seen/done that would be applicable to my situation?
