I have a question,
how do you evacuate so much heat from the room? I intend to build 25 rigs, but that's over 20.000W, how could I keep the room moderately cold? Here there can be 38º celsius on the street in summer
Regards
Step 1- Calculate the volume of the room (LxWxH).
Step 2- Multiply the volume of the room by the required room air changes.
Step 3 - Divide the answer by 60 minutes per Hour to find the required room CFM
Take that CFM and find a blower system to do so.
