I got an Antminer E9 Pro running in a room that's 2400 cubic feet (8ft wide x 25ft long x 8ft high). If I want to get rid of the heat in that room, is there a way to calculate the CFM rating for the fan I should use? There's one AC vent and I can also slightly open two doors to let some fresh air in.
Yes, there is a formula that you can use to calculate the cfm that you need for that room.
Here's the sample
(Feet wide*feet high*feet long=cubic feet)
6*6*10=360
Multiply it by 2
2x360=720
And then divide it by 60 to get cfm the result should be 12cfm.
Why not just exhaust the hot air directly from the miner using duct host if it's not many?
That's interesting you say that as it gives me a new idea. If that calculation is true then that means I could get an 80cfm bathroom type of exhaust. I could then put said exhaust in the ceiling tile (It is a drop ceiling in a warehouse) and vent the heat into the ceiling. Would that work? Does that trap the heat in the ceiling and not affect the rest of the room? It does have sheets of thick insulation in the ceiling. If that would work it would be perfect. I was initially going to vent it outside as there is a part of the room that has a wood wall that I could put an exhaust in but those types of exhaust are generally like 700cfm which would seemingly be too powerful. Thoughts?
*edit* Actually now that I think of it. The best way to vent it out I am going to assume is to just vent it outside.
That is cool to know that we have formula for even calculating the power needed to vent a room. Makes the life more easy. Though I am not into mining yet, I am always getting engaged in the conversation like this.
Recently I also posted about the cooling effect of the immersed hardware in BitCool coolant. This makes the venting issue go away since you are taking care of the heat with the help of Coolant that is circulating through the hardware chamber and taking away the heat on continuous basis.
However, in your case since it is just single unit with no complex farm, I think a simple vent will do it's job rightly.
Moreover you can also position a normal fan on one side that will point out to miner in such way that it will push the air towards Vent and rest will be taken care by the exhaust. If operations start to go above mid scale then you can think about the BitCool Coolant tanks.
