I am in a very similar boat here in Central Florida. I am no HVAC expert but was wording if the following would be possible……take a portion of my existing warehouse and build two small insulated rooms divided by Server Racks. Then use an evaporative cooler set up in a closed loop configuration, similar to the attached diagram. The humidity output by the miners should be low enough for the evaporative cooler to work properly. The server racks would pull cooler air from the room with the evaporative cooler and push the exhaust to the other room. There would then be a duct that connects the two rooms together to feed the evaporative cooler.
Am I totally crazy or would something like this actually work?
The Evap(s) should be placed at the input of the "duct", but otherwise that's somewhat similar to my current setup where I am at now.
I'm doubtful it would work AS WELL as where I'm at, as the air around here tends to be very dry - but it should help some.
DEFINITELY invest in a humidity meter to keep an eye on the RH at the intake of your miners when you try it out - I rarely see anything over 40% RH (and it has to be actively RAINING outside to get close to 50) but the humidity in my area tends to be very low.
I don't bother with the "duct" as such - I put my evaps in the "hot output air" area and the output of them pointing at my air intake area.
I currently have 2 Brisa "window" type units (BW3004 units IIRC, both bought during "end of season" sales from the local Ace Hardware) stacked on top of each other with some boards for spacing, and enough space that I can add a 3'd one on top if I need it in the future.
