I am currently using 40kw of electricity for my miners and was wondering if a 2.5 ton AC would be sufficient to lower the ambient temperature between 80-90 F. I have a 3000 cfm fan pulling air out of the room and a 3000 cfm fan bringing in 80 F air in. The room temperature is 115 F. Any suggestions would be helpful.
some math 40kw is 40,000 x 4btu = 160,000 btu a 2.5 ton ac unit is 30,000 btu.
So my guess is no it will not drop your temps from 115 to 90.
40kwatt is close to 100 s-1's
what miners do you own?
Mix of S1 and S2. How many btus would be needed?
I have to find my ac books as there is a formula. Do you know the measurements of the room.
Height x Width x Length gives me cubic ft. Also you have 80F temp for intake of 3000cfm air.
Will that go to a higher number in the summer?
http://www.rapidtables.com/convert/power/kW_to_BTU.htm your 40k load is about 136485 btu. If you feed 80f in at 3000cfm it helps cooling somewhat.
If you pull 3000 cfm out in hot air it helps. since you are gaining 35 degrees 115 in room vs the 80 coming in.
you need the extra cooling.
My home is 2000 sq feet well insulated and I have a 2.5 ton ac unit.
when it is 100f my ac needs to run constantly during the day to keep my home at 76f this is a 24 degree drop.
you are looking to drop 35 degrees which is 50% more. also you 'sun' never sets. ie the miners run 24/7.
so you are looking at at least a 4 ton unit.
but the rooms size and the 80 air being pulled in are factors needed to see if more then 4 ton setup is needed.
