Fascinating, but this system is not going to have a pressurized hot air / cold air isle containment? Your airflow may have potential issues, have you considered the combined CFM of the individual miners creating static pressure bubbles?

One way we overcame a lot of our cooling issues was simply tripling the average CFM to KW standard that most data-centers use. By removing heat rapidly from the environment (think wind tunnel) we have had 0 cooling issues. How have you accomplished this or expect to accomplish this in your open floor / white-space model? Hot-spots still exist, and blow back is your biggest enemy (when miners pulling air into hot air isle exceed CFM airflow of supply) they basically then push hot air back into cold isle and suck it in again (thermal loop). You won't notice this until you start to get to at least 50% capacity. Just wondering how you guys deal with that aspect.

#2 - Hot spots. We actually have a *lot* of control over the power and heat density of our equipment. We can respond to hot spots not only by adjusting cooling, but also by adjusting miner's physical locations and/or densities, something datacenters cannot do.

Based on your pictures it doesn't look like you have the ability to control direct / localized regions they way you describe. While you might be able to adjust cooling capacity to a particular area, the effect is cumulative. It really comes down to gross airflow, and what you're describing doesn't directly correlate to the individual miners CFM flow - that add up to be a lot more than you think. For example 250 S5 units have a CFM cumulative effect of 30k CFM, only pulling about 100kw, calculate that at a megawatt level, 300,000 CFM worth of airflow generated by S5's for 1 MW of power.... If you can create a wind tunnel effect, and have 300k CFM being generated by larger blowers (more efficient than 250 - 90mm fans) you can reduce the amount of power draw and rely on larger units.

It also means customers units stay cooler and work more efficiently.

Just hoping you engineering team considered this on the design for your circulation of the airflow.... Perhaps I'm wrong and you've modeled this more, just going off of what I saw in the pictures.

I am not affiliated with ASICSPACE just copying something from an Earlier post it seems to me with he amount of money they would have to invest into this property they would have thought this through. If you go to the second page of this thread there is a lot of information from them on cooling arrangements as well as BTCtalk members suggestions.
