Hi, folks.
My brother asked me to help him set up a room for his mining rig. He has several
Avalon 741 miners and I want to compute out how much fresh air I need to inject to the room. It's a small, enclosed room.
What I'm planning to do is use the maximum air flow that the fan of a single machine can handle and the number of machines to select an appropriate fan and size the ducts. I know my way around ventilation, but I have zero experience on setting up mining rigs, so aside from getting the air flow specs of this particular machine (which I can't find online and I don't have access to the miners at the moment), I could use some advice in this regard.
Am I going about doing this the right way? Is there something else to consider?This is more or less what I'm planning to do:

Any advice/input will be much appreciated.
EDIT: My brother also has a couple of 18.000 BTU/h HVAC (we live in a tropical country, and temperatures range from 27 to 30ºC) but I think that the heat load of the rig is much, much larger than the HVAC units capacity, so I'm not really sure how much of a difference it would make.
exhaust is the key.
1 machine = 1x 200cfm fan and about 1200 watts which is about 4100 btu
6 machine = 1200 cfm and about 7200 watts which is about 25000 btu.
if you feed in 2000 cfm of air but only some from the ac unit and suck out 2400 cfm
with only some ac in you will be fine.
I would blend in some a/c enough to drop the intake air to 28c at a 2000 cfm rate with exhaust at 2400 cfm
