Whats the total CFM capacity this facility has? Also, what type of 'cooling' infrastructure do you have to keep all these miners cool? Evaporate cooling only? What do you expect your intake temperature to be with the maximum wet bulb during the year? I have no doubt when its 30 degrees outside you have no problem keeping this place cool, but based on your design you don't have controlled hot air isles.
Honestly it looks like this place and all the equipment is going to cook when the temperature reaches 75 degrees / 80 degrees and they have 1mw of active miners running... Once you reach the tipping point, the temperature will rise indefinitely until units are shut off...
Do you know exactly how many BTU's only 1 mw of equipment will put out? 3,412,142 BTU per hour, that takes, 285 refrigerator tons to cool.... With no redundancy... I'm sorry I look at that ducting, and it appears no rhyme or reason was put into the facilities air cooling capacity layout... I've spent tons of time in data-centers before, and this thing looks like a disaster when your ambient temperature and wetbulb start to hit your summer months... Its one thing if you have duct-ed / forced airflow and can provide 200cfm per KW (150cfm is standard per kw in normal environment) to dissipate / remove the heat out rapidly (200,000 cfm for 1 mw), but I can't figure out how you will accomplish this in your current configuration...
I mean I'd love to be proven wrong here, but what type of capabilities does your environmental system have to actually keep this equipment cool outside of the winter months?
Let me tell you, next gen systems like spoondoolies etc, hate it when the temperature climbs above 80f - 85f degrees
Funny you ask about HVAC. We conducted a white smoke test yesterday, analyzing the airflow rates and patterns within the space and mechanical systems. The testing involved a 20,000 CFM white smoke machine.
Here are some videos:

Will double the capacity of both supply air and exhaust air before the summer, as well as add several 60 ton compressor based AC units. We track hotspots based on a 3D grid of temp sensors we have in the mine, and will be adjusting ducting and containment to deal with any problems.
As you can see, the 20,000 CFM of white smoke clears in a matter of seconds in these videos, which is a visual verification of the fact that the room is changing air at the shelf level every 5-10 seconds currently.
