I've been asked to figure out a venting system for an ageing cave that is 400 square feet. Given that the ceiling is 8 ft, that's 3200 square feet of air. I plan on rigging an air scrubber, in conjunction with a passive air exchange accomplished by a low vent for incoming air, and a high vent for outgoing air.
With a passive air exchange, is the air scrubber necessary, or overkill? What size vent would be ideal so as to not have extreme air movement (drying out the cheese)? Is ideal placement of vents on opposite wall, same wall? How about taking into account the location of the cooling unit? Should I keep the exhaust vent as far away from the unit? If the cooler blows from north to south, should the vents be on the east and west walls?
Thanks for any suggestions.
