Title: Moving mining equipment into a shop - a couple questions Post by: darkshad on March 15, 2018, 03:18:41 AM Hey all.
Looking to move and possibly expand my miners to a spot in my father’s shop (in the process of trying to get a 400 amp single phase 220 circuit added) over the summer and have a couple questions. The plan is to put my miners in the back corner of a metal building – there are 2 large garage doors (RV sized) and then 3 windows on the opposite side. The ceilings are 20+ feet tall. I am planning on putting my miners in a ~10x~6 area in one corner of the building (where the current dog pen is now). Please see the link below for pictures and a small video to get a better idea about the space. http://mu.org/~youngqui/shop/ My plan was to use one of the windows and put in a big intake fan, and then on the other window put a big exhaust fan. Or, I’ve thought about just putting two big exhaust fans on each window. Thoughts on which one might be better? I live in Missouri and it does get quite hot in the summer, so exhausting the heat out as fast as possible with 2 exhaust fans seems to make more sense to me Since the ceiling is so high (and hot air rises) and there would be a large part of the space I wouldn’t be using, would it make since for me to try to build a small 10x6x8 ft room for my mining gear (I was planning on buying a cheap metal shed or could just add some plywood to the dog pen that is already there) or don’t worry about the heat – let it rise and then the exhaust fans will suck it out? I will probably add between 10kw – 30kw worth of miners for now. Next thing is electrical – should I have the electrician add 30, 50, or 60 amp outlets? My thought was I’d add 50/60 amp outlets and just get some mondo PDUs, or would it be better just to go with multiple 30 amp circuits and hopefully cheaper PDUs? Any good place you would recommend at finding good, cheap used/refurb PDUs other than ebay? Appreciate any thoughts you can provide.

you can build a tunnel with this http://www.farmtek.com/farm/supplies/prod1;ft_tekfoil_insulation;pg101382.html wrap around this https://www.ebay.com/itm/Apollo-Hardware-4-Shelf-NSF-Wire-Shelving-Rack-18-x60-x72/232663482915? This rack can do 5 s-9s on each shelf 20 s-9s pull 28k-watts there are a lot of ways to set gear up. a 20 amp 240 volt circuit will do 2 s-9s you don't need pdus each circuit can go to one outlets https://www.ebay.com/itm/NEMA-L6-20R-20A-250V-Twist-Lock-Electrical-Plug-L6-20-Female-Receptacle/282880895372? that outlet can run this cable https://www.ebay.com/itm/L6-20P-to-2x-C13-Y-Splitter-Cord-10-ft-15A-250V-12-AWG-Iron-Box-IBX-2803C13/111177581003? that cable can do 2 of these https://www.ebay.com/itm/1600W-BTC-APW3-PSU-Mining-Power-Supply-For-Bitcoin-BTC-Antminer-S7-S9-L3-D3-US/152925615110? |
