That help immensely! Thank you so much. We'll aim for a 1:1 ratio. Looking at evap coolers now 
not sure. what this means
l _ l
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?
so can you clarify the dimensions as 9m (h) * 5m (l) * 4.5m (h)
is wrong you are missing 1 w and have 2 h's

9m (l) * 5m (w) * 4.5m (h) Sorry, typo! Yes, so the room is 9m long and 5m high

I am sure it can't be 9 meters high, so it's 9m for width, 5m for long and 4.5m for height, Kuwait has an extremely hot climate, above 40c/104f is pretty average around noon, that is a ton of heat he needs to get rid off.
I would stay away from evaporative cooling because the humidity it generates is more harmful than the heat on those miners, I can't give you a detailed advice, but for a 300kva/240kw worth of mining gears we currently have 19 8000m3/h aka 4708cfm fans, 10 for exhaust and 9 for intake, they are moving a ton of air and the miners are doing just fine even in extremely hot days, all gears are set to manual fixed speed of 100% (5000-6000rpms), and of course, no overclocking, in fact a few them are underclocked during the summer.
You could use that as a reference, but none of the above was based on scientific facts, it was simply trial and error which eventually worked fine.

they separate hot and cold aisle a must in a tiny space.
Thank you, I'll check this out
Hey All,
I'm working on setting up around 100 S19 Pro Antiminers and am scratching my head about how to cool 330 kW. Also, I've calculated my miners would move around 25,000 CFM. Do I need to provide equivalent cool air?
Here's the issue: my space is super small. The dimensions are approximately 9m (h) * 5m (l) * 4.5m (h) and I've designed racks to be in a sort of shape like this |_| where hot air will be separated by a divider.
What do you guys reckon I need? Evap coolers seem like a good option, but a nightmare to regulate the humidity.
Would appreciate input, thank you!
