Air Distribution
If you think of the controlled environment of a data center as a cocoon, it's easier to imagine how forced currents of air are heated and cooled in a continuous cycle. The basic principle of convection is what makes the system work: Cold air drops, hot air rises.
The cycle of air flow in the room follows this basic pattern:
Air is cooled as it passes through the air conditioning (HVAC) units.
Conditioned air is forced into the raised floor void and directed up into the room and into equipment racks by means of tiles with perforations or cutouts.
Conditioned air continues through equipment racks, cooling components.
Heated air from components is forced out of the racks and rises toward the ceiling.
Warm air is drawn back into the ...
