A large mining farm would require lots of AC power. It doesn’t take many miners to overpower an AC.
AC is actually the last way you want to cool your farm it's just to expensive. First is evaporation cooling, but it does not work in all environments. Next I would say is using CFM's of fans/exhust to move hot air out.
AC no large scale bitcoin mining operation would use.
Is AC expansive because of initial price or because of the electricity? He has almost free electricity.
I agree with you, evaporative cooling is very effective but lots of CFM, if sufficient, would be my first choice.
Another option would be 2 phases immersion cooling. I've researched deep into this technology and concluded it doesn’t really apply to northern climate like here in Canada. The new 16 nm Bitfury chip and its large overclock ability might make me reconsider using 2PIC.
AC is expensive possibly because of both. But the ongoing cost's for running it are what keep most from using it. The miners can just put out a lot of heat and get's expensive.
There is a point that standard AC in most houses were not meant to cool down. If you had enough miners the standard ac setup would not be enough, rooms normally are not set up with asic cooling in mine. They are set up thinking about keeping it cool is much easier conditions. Most normally don't get this point though due to the cost of cooling miners with AC.
