 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

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

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 ?

1 KW * 3412 = BTUs

1 KW = 1000 joules per second

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.

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.

You'll have to calculate by electric usage. Then you will have the numbers.
