The room with my miners currently has a humidity level of %12. The air is very dry, I am not sure at what point it will become a problem....or what I could do about it? I suspect a humidifier wont accomplish much as the hot air is being exhausted outside, so any humidifying I do will just be exhausted out as well I think.
don't mess with it, 12% is low but better than 70%+
in fact ideal range is between 30-60.
Just exhaust the hot air out and pull in outside air with filters, that should balance the humidity
Nope, it doesn't.
Keep in mind that the heat generated by the miners causes the room air temp to go up which drops the RH.
I had *2* big Brisa units AND a small "misting" system running in my mining room (which is perhaps 500 square feet) and even when it was RAINING outside (which was bloody RARE last summer, we went about 2 months at one point with ZERO rain and 3+ months with a single rainy day) I never saw 50% RH - mid-40s was as high as it ever got.
I'm currently in the process of revamping the air system to push more air through the room, as the temps were getting pretty marginal at times during the major heat wave we had.
Electronics is generally specified to work between 20-80 % RH, sometimes wider, as long as it's "non-condensing" (which will NOT be a problem in a miner due to it's heat generation) that's the critical part.
Also, higher humidity levels help keep dust count down some.
