not sure. what this means
l _ l
I believe the middle underscore _ means the wall/separator whereby the miner will go through it, just like the average set-up most of us use to isolate the miner's intake from the heat.
but he will need very good separation of hot from cold.
He sure does, with only 5 meters in width there isn't enough room for the heat to sit in before crossing back to the cold section, and thus the exhaust will need a lot of work, I would use only shutters and fans and no walls.
The hot air wall would look something like
shutters - fan - shutters - fan - shutters - fan - shutters - fan
fan - shutters - fan - shutters - fan - shutters - fan -shutters
This will result in a very good air extraction and if you haven't build the wall yet, it might even cost you less, all you need is galvanized steel pole tied vertically and horizontally creating squares/rectangles to hold the fans and the vents/shutters.
Exactly. So we decided to use a ton of wall and ceiling exhaust fans that move around 5k CFM. They are shuttered and will be direct air directly outside. My only concern now is providing the miners with enough cool air. Since we're going to be moving at least ~100k CFM of air OUT of the room...shouldn't we provide the equivalent in cool air?
