Hi, i have found some investitors who wuld like to buy about 200 antminer s9, and so we make an order, now i need to build a room for them, any suggestion how big room i need? how much of heat one miner produce? i was thinking on putting something like 1oo m2  room 3m high. and to put some aircooling on the floor from start to end down on the wall with cold air enter on every 2m.  an summer time it is about 30 degree of celsius outside. here i will post a photo of room how i think it wull be ok. i will like to get some other opinions and critick if i am wrong. ty https://imgur.com/a/aiEJb      https://imgur.com/a/aiEJb    here is the room where blue is cold air in, red are miners and green is opening on roof for cold air out. and also there will be big fan on the floor to push hot air out to opening on roof.
