I am proposing to build a cooler room (like at meat packing house) and run them in there. Will that work? If so how big should my room be?

It will not work, try placing a regular pc in a closed freezer and see to yourself, miners unlike dead cows generate heat consistently, you need to get rid of the heat and provide fresh cool air for your miners, what ever you have in mind won't work if it does not have some sort of ventilation.

Good day guys

I am trying to figure out the same thing. My electricity is free some that is not my problem. I have 61 S9i miners and I am trying to figure out the best way forward with them. I am proposing to build a cooler room (like at meat packing house) and run them in there. Will that work? If so how big should my room be?

You simply need a massive powerful fan.

There are some that move 14900 cfm cost under 2k installed.

My solar thread shows one and a link for it.

I cool 63kwatts of juice used.

here is a post on it.

The fan is installed it is a beast Cheesy

It moves 14000 cfm+

1hp motor 230 volts at 5.5 amps or about 1 s9 Grin

temps dropped 25f in 1 hour run time

S9(14TH) is 1372W gives you 4681BTU/h or 1372J/s or 0.39TR (Tons of Refrigeration) of cooling load.

but using air-conditioning unit will use a lot of electricity which will add up to your operating cost of the miners. You might end up losing money due to electricity cost. It will be better to vent it out of your room using a fan and/or inducing colder air to your miner.

S9 gives you around 250cfm of hot air.

Not really sure of what your mining environment is but, don't look to cool the place. Using AC will kill your profits, unless your electricity is free.

You want to remove the warm exhaust from the miners, out of the space as soon as possible there are quite a few designs to do so. One being a hot room cold room design.

With more details of the room size, ambient temperatures and how many miners you are going to run, the forum can provide a bunch of useful information.

1 KW * 3412 = BTUs

1 KW = 1000 joules per second

Thanks for the reply

It turns out that one ANTMINER S9 gives out 1400 watts per --- area of the warehouse 14 m2

How do you think this is right ?

Just assume 100% of the electrical consumption is converted to heat, which is an excellent assumtion, and you'll get the right answer. Wink

Given

"1127W (11.5TH/s batch), 1225W (12.5TH/s batch), 1274W (13TH/s batch), 1323W (13.5TH/s batch), 1372W (14TH/s batch) (at the wall, with Bitmain’s APW3 PSU,93% efficiency, 25°C ambient temp). Expected discrepancy of +10%"

It follows that if you were to run any Antminer S9 for a least 8 seconds,

It's over 9000!!! joules; heat emission.

Can anyone help to know - how many HEAT EMISSION joule (J) - Antminer S9 ?

I want to calculate a cooling system for a mining farm

Waiting for your answers....
