Same way you cool the top of a rack in a cold/hot aisle system. Blow cold air up the front of the rack. We measure temperature at select points in the rack. Keep the hottest spot below set point, and everything is fine. The physics aren't that much different.
We are cooling 20kw per rack with this setup. 4 hp c-class chassis per rack. Works great.
Hi Tim, I poked through AFCO's drawings at http://www.afcosystems.com/pdf/AFCO_Drawings.pdf, How much of a size hit is typical? Do you take the depth out to 52" to create enough space in front of the equipment for air to flow and take the 6-inch hit to the side for the cabling sidecar? What's the impact with respect to sharing the facility with non-AFCO cabinets? I would imagine that with a bunch of these things dynamically changing their air flow it would be hard to maintain a static pressure under the floor. Regards, Bill Herrin -- William D.
