couldn't find the "Picture of your mining farm" thread so i guess this will do.

Was but the room turned into a furriness hitting 47Degrees, the A/C units are shit anyone any recommendations on cooling that doesnt involve proper DC grade heat extraction and recovery?
Its not hard, work out how much power (energy) you are pulling out and then get the equivalent amount of cooling power.
Heres some ideas to get you going:
Heat is measured in either British Thermal Units (BTU) or Kilowatts (KW). 1KW is equivalent to 3412BTUs.
Most aircon units are measured in BTU's so I'll work in that unit.
Equipment BTU = Total wattage for all equipment x 3.5
Room Area BTU = Length (m) x Width (m) x 337
Lighting BTU = Total wattage for all lighting x 4.25
There seems to be no windows, or people working in there permanently so you can probably leave those calculations out.
Total Heat Load = Room Area BTU
So you need enough aircon cooling to handle that amount of heat.
I'd say on equipment alone you would need minimum 100KW or 350K BTU's of cooling
It only appears that you have two of them, thats max 50K BTU if you have the most powerful (25K BTU) wall-split units, so you would need 14 of them.
100kw - 110kw of power you need to cool. (Took the power numbers from https://www.youtube.com/watch?v=OVQkQ37BGhk)
1 RT = 3.5168525 kW so you need ~32.1 I would round up to 35-40 tons.
That is two large CRACs and outdoor condensing unit. Most of the stuff has a 45-60 day lead time, plus budget 1-2 weeks of install. I would hire an engineer and get it done right. No real do overs.
