Airflow to the environment is your only answer.

I rented a warehouse space with 100KW 3-phase electrical service. In Texas. Airflow in and out is all you need. Filter the air and keep dust out of your units. Still need to clean them occasionally.

Bitcoin mining is the process of turning electricity into money. AC cooling will triple or quadruple your power bill, likely sending your costs beyond your profits.

Standalone portable AC units need to exhaust their heat somewhere, if you are exhausting this outdoors, then you can exhaust the miners outdoors.

Experiences

- Miners slow down a bit when ambient air is 100F
- Miners don't do well when ambient air drops below 32F because of heat stresses across the board from one end to the other. Too much temperature gradient.

Op said one unit or 3.3 kwatts.

He does not mention power cost.

If he puts in a 10,000 btu portable ac along with the ac that flows into the room. The room should be cool assuming he dumps the heat via the attached vent to the portable ac.

is it efficient no. but power cost may not be an issue.

will the extra ac cool the room if he vent the ac exhaust into the room no.

Ac moves cold in and dumps heat out. the vent on the portable ac is clear in the photos.

his idea will do 1 s19 if that vent dumps the air out of the building.
his idea will not do a s19 if the ac vent does not dump the air out of the building.
