Alrighty.  So I've finally received all my materials this morning.  Was waiting on the fans to arrive.  So I'm starting the setup of my mining room for anticipated machines.  Already have 5 Avalon 741s on hand and want to get ready for the rest of the gear on its way.  There will be approximately 4840 cfm (22 @250cfm) of air exhaust by the machines.  (total of 22 machines bought and paid for so far, with possibly 5-10 more machines in the works soon)

Feel free to critique or recommend anything else.  I start this Friday putting the wall up to separate the room.

Room dimensions are 8'Long x 8' wide x 7' Height

The wall with the mining rack will have cutouts for the miners exhaust to fit into the exhaust room.



This is the fans I am using:



Here is the room as it sits right now.

I would go for 2 fans for exhaust or 1 fan for exhaust and 1 for intake, sort of fail safe redundancy should one of them failed. Your fan is a monster by the way, it can displace entire room volume by 6 times plus. I would optimize for slightly smaller - lower wattage one. Or run it at lower speed.

Looks good, I would try and make a separation on the patio between the exhaust and intake fans, maybe even duct the intake fans out and have them make a 90 away from the exhaust fans. Anything to prevent the chance that your exhaust feeds into the intake fan, seeing as they are positioned rather close.

And I'm sure your already planning this but clean up the walls and floor, make sure you have no loose debris or paint that could flake off of the walls, as with those airflows it wouldn't be hard for something to get picked up and run through your nice new miners. Good luck looking forward to the finished product.

EDIT: sorry I just saw the second hand drawing, what is the PTAC room that you are using for intake?

The fans do have an adjustable controller option.  I'm not sure if I will use it yet.  Also they have a temperature module, and I was planning on bypassing it but I have a spare intake and exhaust fan in the plan as well, and was thinking I could keep the temperature module wired in them so they would only cut on if the temperature reached a certain threshold.

You are right though about having a little bit of redundancy especially with the amount of heat.

I totally agree with you about putting a separation on the patio area between exhaust and intake fans.  I really liked the idea and will for sure implement something into the setup as such. 

Most definitely there will be final touches and cleanup, but we basically pulled off old things that were attached to the walls and left it as is for now until we build the separation on the inside of the intake/exhaust areas.  Then we are going to 'finish' it and of course will be putting in new LVT flooring or VCT tile depending on what we have in excess from leftover work we do in the property.  I've got a room full of this and that comes in handy with leftovers of various repair jobs we encounter.

The PTAC is a 15,000 BTU air conditioner that I was planning on putting into the slot.  I have lots of these units in spare (these units are normally used in motels/hotels for through the wall installations) and figured I'd just put one in that slot on the right window bottom as that is what is supposed to be for.   I'm not planning on running the AC but figured for the really hot humid days we occasionally get (I'm in South Carolina) I figured it couldn't hurt.  Since there is not additional investment of actually purchasing the unit, and its just sitting in the storage rooms on pallets figured I'd snag one for the 'mining room'.

Lemme ask you this... How many ac units you see in any farm?

I do not see the power there to run this farm either... you wrote 200amp panel 3 times. Did you mean a 20 amp circuit? Are they 220-240v? If your on 110-120v your already behind. Guess your pics dont show your "200 amp panels" BTW, Based on the receptacles, those are 15 amp not dedicated 20's. A true 110/120v receptacle has a slot in it and their plugs will not fit in a 15amp. Like this...



Forget the frigging AC and let the air flow. It is foolish to try and cool them. Let the air do what it does. Smiley

Snag one for the server room running your wallets. Which is not in the mining room.

I do see your point on the AC.  I am likely to take your advice and forget about it.  If I do then that means I will be able to make my intake vents even closer to the ground.

As for power actually that is being installed this weekend.  Yes it is 3 200amp panels.  Having multiple Nema L6-30R installed as I am using 30 amp PDUs on 30 amp breakers.  And since I will have 220 I am using power supplies from parallel miner and some from bitmain.  That receptacle we see in the picture is what was prewired in the wall.  It will probably hang around but won't be powering much other than maybe a desktop to remote in on the same switch to do some monitoring etc.

 Now your talking! Sounds like your headed down the right path. That is very similar setup as both my farms. If I can keep finding these cheap I will bet set! Bought him out when he agreed to sell all for $34 each.

 BTW, try not to mention Parallel too much as too many people getting on my source! LOL They went up $90 on the good PSU's this week as they got a different source. Sad I will say this though, they threw in $100 worth of goodies to try and make it up to me. Their customer service is amazing.

I got 8 of the exact same.  Been looking for a few more to have as backup and to be ready for next expansion.  Took me a while to browse and learn what all I needed and takes time to get all these things in and getting time to do all the physical work as well and maintain normal life,work, etc.  But taking my time and learning all I can so I can be better prepared once I max this room out at this property.

Also you are so correct on the price increase.  I was waiting for like two weeks for items to come back in stock and then when they finally did, price did significantly increase.  I guess with BTC increase its just increasing demand.

Using both intake AND exhaust fans is a waste.
In fact, if your "cutouts" on the miners are tight enough, you might not need additional fans at all - the fans of the miners should get your air circulation going.

 You WILL need more space for air intake and exhaust though if you are planning to run 600 AMPS worth of 220V mining in that room - most likely you'll need to replace BOTH windows with louvres or some such.

 Breaker panels on the cold side and well away from the window is a VERY GOOD idea - don't change that part, except perhaps to put ALL the panels on the back wall not just 2 of the 3.
 Breaker panels CAN be mounted in a vertical stack, if you leave enough space between them for wiring access - the code spec for "required height" is pretty wide.

I'm no longer legendary just in my own mind!

Thanks for your input.  I do plan to make it as tight as I can.  Of course will try to seal it in air tight with some good sealant in areas that are hard to 'maneuver' around.

Yes the breaker panels will go on the cold side at the back wall.  There were some updates so now going to do only 2 200 amp panels instead.  See below as I will post updates on my adventure.  I hit a snag on the electrical portion, but already have solution and hope to remedy by Thursday this week.

The windows are completely removed and boarded up.  We installed fans.   See my updated posts following this one.

So got started on Sunday afternoon doing some work in my spare time.  Been a busy few weeks with acquiring another business and halloween etc.  But finally did some work on the mining room setup/project.

I'm trying to take photos as I go so maybe it will help other or give people ideas on what to do.  I'm learning as I go so I will make mistakes, but the feedback from the forum has been great and gives me perspective I may have overlooked.

I've posted some general photos of what has been done so far.

Few speed bumps I hit.

Home Depot screwed me up good.  I ordered some louvers vents for the exhaust section.  They sent me two in packaging with the right model numbers, but one of them was a different product inside the box.  So I was only able to get one aluminum vent mounted.  The other hole we blocked off temporarily until we get the replacement vent.

The fans were a bit larger so they had to go a good bit above the floor because of the space constraints.  I didn't want to remove the aluminum window framing as if and when I do expand I plan to restore this room back into the storage/office area it originally was.

The worst setback was me not knowing that my property has 3 phase power.  I had purchased 3 200amp Siemens single phase panels as that was what I am familiar/comfortable working with.  My electrician buddy who was going to mostly do all the work but let me help him, enlightened me that he could make it work since he did some sort of load test on the 200 amp source breaker to make sure it would trip out.  But then I would have to remember that two poles would give 220 and then the next would be a single phase which it didn't make sense to me and was confusing the hell out of me.  So I told him would it be better for me to have a 3 phase panel and he said ideally that is the best route to take.  He's aware of my skills, and that I would be okay, but I have various guys working at times and didn't want to risk someone getting hurt over trying to 'make things work'.  So we placed orders for Siemens three phase load centers.  (Almost double and some more than the single phase price).  So hopefully will received the new 3 phase panels this week.  Also he recommended that I only put two load centers at first and he would 'pre-run' the third panels wire but not tie it in.  Just have it wrapped up and put away so that it would be easier to add into the future without much work involved.

If I was do it again, I would stack the fans vertically not horizontally as it ate up a lot of the space.

Here some photos of what we did so far.

Removed the glass windows and the frame pieces holding the windows.  



Made a hole in the floor for conduits for the wire on the cold side.



One window boarded up.  Each window uses two sheets of plywood.



Both large windows boarded up



Prepping install of the exhaust fans.  Marked and working on cutting out.



First hole cut out for exhaust.



Holes cut out and fans mounted for exhaust and intake sides.



So fans are mounted minus one exhaust vent.  Returned the old one and picked up new on at the store today.  Plan to get some 'free' time and work for a while finishing things up.

The hot wall...



Inside the hot room and looking at the exhaust fans running.  Need to get those few loose cables tied up now that I see this.



Intake wall on the inside.  I use cheap filters that I change out each Sunday morning.



The worse looking rack of wires, but I've been busy with work.  Once I get some more machines to fill in the spaces I'll clean it up and label everything.  



My vertically mounted breaker panels.



The finished exhaust and intake wall.  I will probably need to separate the two with a partition especially once the warmer weather comes to prevent pulling in the hot air being exhausted.  Board temps are doing good staying in 33-46 range.

I envy you and the setup you have going on. We need more people like you to decentralize the monopoly of Chinese mining farms.
I am curious as to where you are located and what power is like. Judging by the plaster in the walls I am guessing somewhere in the Southern USA? Smiley

I'm in South Carolina.  Power is roughly 10 cents here for me.  I hope to grow a little bigger in 2018, possibly looking into GPU mining next as I better understand it.

I like what you have going on there.  I have a mining room I'm remodeling AGAIN for a 4th time and THIS TIME will be it for the mining room IN MY HOME [Downstairs].  I'm currently helping my dad with one in his garage.  You'll get an idea of what I'm doing downstairs in my home with what I'm doing with my dad in his garage:
