There are a lot of variables, this is not a easy thing.  Any pictures of how you have them set up?

What is the size of the warehouse?  Height?  Can you cut a hole in the roof?  Does it have any dock doors?

Very true if you do not own the building you will need a landlord who is easygoing on modifications to say the least.

Also what budget do you have?

30 Thash/s, how many Watts are we talking about here? I don't know the current miner configurations from our Swedish friends! On a side note: They just released a statement that they're mining in a hangar in northern Sweden with its doors wide open, in order to use the arctic wind as a natural cooling solution. The personnel and the miners can also enjoy the clear night sky!

Master airflow if outside air is available use fans
build/deploy hot aisles and cold aisles
Put chimneys on the back of your racks to direct the heat up and hopefully out


mark at blunthammer and I am happy to give you better answers if you can provide more detail

first of all you need to give us the idea of how much is the area of your warehouse then only we will able to calculate the proper cooling equipment which will suit your needs.

So it's 2,000 square feet

~3 TH per rig and you said 30 TH so 10 rigs

1.95 Kw per rig, so 20Kw is the draw

What I deduce is that you are having trouble cooling 1 rig with 200 square feet of ambient airspace per rig. What is happening? Are wires melting or are people melting. Is there hardware failure? Fire?

That is plenty of space (ambient) to maintain a temperature, unless it is closed. If it is closed then you will have issues. Again, master the airflow. spread out the rigs, make sure hot air blows one way and is directed out of the building somehow with fans, chimneys or a combo.
