underfloor air distribution
underfloor air distribution
(OP)
I have a long rectangular computer server room (20' x 70')that I am designing a underfloor hvac system for. The underfloor system will provide air directly to the servers through cut-out floor panels. The problem is that the client wants the hvac units in the far corner of the room. With the long rectangular nature of the room, I am afraid that the supply air underneath the floor will never make it to the other side of the room. Does anyone have any suggestions? I see that there are underfloor fan units available but I am not familiar with how well these work.

In addition to sealing the holes, make sure there aren't too many cable trays under the floor which will block air from reaching the target area.
Also, be sure your client doesn't make the mistake of placing several rows of servers all facing the same direction. Most server racks draw air into the front and exhaust out the back. You don't want hot exhaust from one row blowing into the intake of the next row. This will diminish the capacity of the AC system. Server racks should be lined up face to face and back to back, creating "hot aisles" and "cold aisles". There is good research on this published on www.upsite.com
