We've got a rack room in a project where we dont have AC.
Ive got a room which we plan to setup as per the rough diagram here. The rack room has 3 external walls.
The rack is an open frame rack with no sides / back and no fans on the rack itself other than the fans built into various equipment.
Ive vented rack rooms like this before and its worked, but id like to know if there is some way i can calculate the required fan / ventilation requirements.
I can get a total CFM for all of the hardware or a total BTU output, would it just be a question of making sure that the extract fan has a greater CFM output than the total output CFM output of the AV hardware ?
