Server Room ?

Here's a question for the admins out there, our server room has 9 dell power edge somethings anyway we have a air conditioner that runs 24/7, well the guy I work with has half the ceiling tiles removed so from what he says the air doesn't become stagnent, well I say isn't that what a air conditioner does, pulls the warm air out of the room which makes it cooler. I say put the tiles back in and seal the room tight and let the air conditioner do its thing, any links to prove my case would be great. Thanks :cool:

I agree, let the AC do its thing and put the tiles back. The AC unit should have a vent system that allows you to recirculate air or take fresh air from the outside.

All a straight air conditioner does is cool the air inside the room. It does not bring in any fresh air from outside of the room. If the room is occupied you need a small fresh air supply duct off the main building ductwork so the occupants don't suffocate. Well, they won't die, but the level of carbon dioxide in the room will rise and the occupants will get tired because of a lack of oxygen. This is why you need fresh air.

Removing the ceiling tiles only increases the volume of the room, and ceiling tiles aren't airtight to begin with. Depending on what type of A/C it is, it might bring some outside air for fresh air if it is a window mounted A/C, but I would have to say probably not.
