Hi guys
I have a little farm in a warm place, im with 75 halongs, 55 S9 and 48 L3+, for now i dont have problems with temperatures, but soon the summer comes and the daily temps will stay between 30-35C celsius.
The machines are in a corridor and have 1,5mt on the middle with a intake (bringing air fro m outside, 12000 cfm), i have 4 12000 cfm exausting fans (two from each side), i make a little draw below
https://imgur.com/3jq6mJxIm thinking about putting a 60000 btus air conditioner right above the intake fan because the asics from the top is getting a little warm and gonna get worse soon, i use this conversor from btus to watts
https://www.rapidtables.com/convert/power/BTU_to_Watt.html and with my 0,04 usd energy cost per KWh gives me a value of 211 usd for 10 hours in a day on 30 days using, is it wright? On the manufacturer website said that the consumption on cold is only 5500w.
If im doing the right math, its not too expensive to use AC in my environment, or i calculate something wrong? I know im not gonna fridge all the place with de air, its just to help my machines to live longer..
Sorry for bad english.
