Building Antminer Shed. Any suggestions on design or air flow?

[shaxs]

Hello,

It has quickly become clear that running a bunch of Antminers in my house is not going to work. Beside the amount of heat and noise they give off, I do not have enough power/circuits to run a meaningful amount.

I currently has a small shed attached to the back of my house near the back door. It is sitting on a cement slab, but only using a little of the slab. I have always wanted to tear it down and use the whole slab and make it larger. So I am going to make it bigger. Shed will be roughly 7x9 feet. And if/when I am ever done mining, I will now have a more usable shed for other things.

I also have a spa which has 60a 220v run to it in a sub box. I dont really use the spa much anymore (tired of maintaining it and waiting for it to warm up), so I am going to use that power for the shed. I will break it down into 2x 30a 220v circuits, get PDUs, and run the Antminers off those until I need more power. I should be able to run 12 ants per circuit safely.

I plan on cooling the shed using something like this: http://www.amazon.com/Pioneer-Conditioner-Dehumidification-Ventilation-Installation/dp/B0095V0OYM/. A split a/c system. In the summers here it gets 100+ degrees so it will be necessary. During the winter and fall, it doesnt get hot. But the antminers give out a lot of heat. So for those time I was thinking about having a built in fan, maybe 2. One to suck in cold air and another to draw the hot air out.

So, given the desire to have a few ventilation fans and an a/c system, how do you suppose I should lay this out? I know hot air rises, so I probably want to put the vent out fan towards the top of the shed? Put the a/c vent near the floor?

Any other suggestions or things I should thing about?

For ventilation at the top, maybe something like this: http://www.homedepot.com/p/Ventamatic-1300-CFM-Power-Attic-Ventilator-Gable-Mount-CX1500UPS/202913798

Now if the A/C and a ventilation fan were running at the same time, would the cold air be sucked out too quickly to do any good? Should the AC be run by itself on hot days?

Hot air rises so extractor fan opening at the top rear, cold air intake at the bottom front.
Sheds get hot in the summer so you might want to make it windowless, or paint it white/silver, or position it in the shadow of another building, to stop solar radiation getting in. You shouldn't need to waste electricity on air conditioning unless you live in a desert.

I live in Texas lol... it stays 100+ degrees for 60-100 days of the year. But see this picture? Where the small shed is where the new one will go:

okay you have a  car port.

low to the ground on the side of the shed that faces the carport have an intake vent.

high facing the rain barrel do the outake fan.



consider  having a white or light color netting for the summer. stretch it from the carport over the new shed to cast shade.   low cost item we used them in the desert and on Diego Garcia when I was in the Navy.

I have a garage not a car port. But the garage gets super hot and would be too difficult to keep cooler and run more electricity to.

sorry read my post again I thought that roof on the other side of the fence near the old shed was a carport

yeah my bad .  but you should be able to do a nice setup .  here is a link for heat sinks . the Chinese seller

I purchased  from the usa guy
with all the fans on the ant miners pointed at the cover back porch they will blow air at the rain barrel .   so A high vent should help. let me read the link on the ac unit. that you posted.

put the ac unit high on the same side as the intake vent.  i.e. the side of the covered porch.

when it runs that air will fall down on the fans of the ant miners. and the ant miner fans will lift air from the low intake vent.

my guess is a timer could be helpful as you may be able to use the intake vent alone in the summer from 3am - 7am.

Yeah rain barrel is going to go. Im going to use that whole slab to build a bigger shed.

I actually picked up an 8000 BTU portable AC unit that draws lower watts than the one I linked for $79 from Sears Outlet. I think *IF* I need ac I will use that.

On those heatsinks, how much do they help?

 testing as I type.  on my 2 over clocked units I placed 48 heat sinks.  i did the last 3 rows of 4 that is 12 on each card 2 ants = 4 cards.
  temps dropped 1 degree and the auto fan dropped from 3280 to 3060  on one unit and on the other temps dropped 3 degrees with the fan dropping from 2780 to 2580.

I have a pulling fan also.  I will photo. give me 5 minutes

2 over clocked one to 393 second to 400 stock is 350

[philipma1957]

all 4 units bottom 2 are over clocked

Rather than go through all that extra trouble and cost I would rather just buy an additional ant especially if you are running a larger amount like 10+. Waste of $ imo.

[philipma1957]

heatsinks on 3 rows

Are you talking in regards to the heatsinks and fans?

well the op is going to struggle to run this gear in the texas summer.

I would argue he should buy a s-2  and not get a lot of s-1's.

but putting out 4k for the s-2 is not easy to do.  op what is your power cost?

I'm OP. I plan on getting some S2s. But the problem still is going to be limited power inside the house. Either way I wanted to build a bigger shed. Not its just running power as an extra cost. Plus I will be housing a friend's collection of miners and he is paying half construction costs.

pull the heat from the antminers from the back of the unit and blow it out of the shed.

Nice! I like that! I will go price out what that will cost. How well does that work? How much power does that inline fan take?

Can you post bigger pictures somewhere? Like a link?
