Youve posted about the hot and cold wall in my mining farm thread. Im up to 38 miners now with another 10 en route. I was hitting the 80s on my miners with 25 machines last summer during 90 degree days. Im sure I will need to build this same wall to avoid overheating in the summer with 50 machines. My upblast fan is rated to 30000cfm. Im thinking if I build the wall halfway up (15 feet on a 30 foot ceiling) it should direct the hot air high enough where the fan should just suck everything out. What are your thoughts on that approach?
if i remember correctly you have quite a large space, 15 feet is more than enough, depending on the width you going with.
if you want to have a decent spacing like mine, then all you need is 11.5 feet of height, which is about 3.5 meters ( same as mine)
with this height you can have 5 rows and the space from the highest miner to the roof will be about 5 feet which is good enough.
here is the initial design
of course having a higher ceiling is better if you do not plan to exhaust air through the ceiling , because if you do, then what matters more is the space from the mining room ceiling to the main room ceiling, if you planing to suck the air out from one of the sides, then the higher the ceiling the better, but i still think 5 feet from the top miner to the roof top is more than enough.
also with 30000cfm i am sure the hot room will not be too hot
, but you will need to have a large intake fan in the cold room, facing the opposite direction of your exhaust fan , because the air pressure created by the 30000 cfm along with miner exhaust fans will be too much for the miner intake fans to handle, they will be spinning at high rpms and the pressure in the cold room will be so low, like latterly you will not be able shut the door of the cold room if it opens to the inside, it will feel like a very strong person pulling it from the inside, therefore you need to force at least something close to 30000cfm to the cold room, which does not have to be a single fan, maybe 10000cfm fan and make a few holes on the side of the wall of the cold room for air to come in easily.
