Abstract
A system for controlling the temperature of a rack includes a connecting plenum configured to receive incoming cooling air from outside a rack for cooling the rack; a front plenum connected to the connecting plenum and configured to receive cooling air from the connecting plenum and deliver the cooling air to the rack, the cooling air being warmed by powered electrical components as it passes through the rack; at least one ventilator for recycling warmed cooling air from the rack back to the connecting plenum to be mixed with incoming cooling air; a sensor for sensing temperature of air in the rack; and a controller for controlling the at least one ventilator based at least on the sensed temperature.
