I am currently setting up a new project. It will be ran two runs in the winters, novemeber-march.
Details:
-structure is a 30x40 shop with 10' walls 14' to the rook peak. metal siding with thin foam insulation between metal siding&roofing and metal frame. ie- very minimal insulation. Building divided in half, into 2 20x30 rooms with seperate exterior doors. About 7000 cu ft air volume per room.
-wired to flip flop 12/12 20 gavitas in each room
-out side temperatures will be lows ranging from 25-40 & highs of 35-50
I need help designing the ventilation system. I DONT have enough power available to run AC or electric heat. I DO have propane vented thermostatically controlled garage heaters for each room that I could use if needed. I have run both naturally ventilated rooms and CO2 enriched rooms in the past, but never with such low outside air temperatures. I know that for the past to have sufficient fresh air I will need to be running atleast a few 12" inlines exhausting and have more then that of passive intake, BUT I also know in this scenario with outside air being cold I will be running to low of tempatures in my room. Please advise?
Considering running a propane co2 generator in a non-sealed room environment where the burner would keep co2 at a moderate level and then when room got hot it would dump the air and start buring again. I figure it is gonna be adding propane heat to get the fans thermostat to kick them on to get fresh air or burn the popane in the co2 generator, either way gonna be adding a bunch of propane.
