The overall cooling efficiency depends on how the air distribution system moves air through the equipment room, how the equipment moves air through the equipment frames, and how these airflows interact with one another. High heat-dissipation levels rely heavily on a seamless integration of equipment-cooling and room-cooling designs.
[7] [8] [9] The system cooling effectiveness (natural or mechanical ventilation) depends on the air flow rate that can be established, the thermal capacity of the construction and the heat transfer of the elements. During cold periods the cooling power of outdoor air is large. The risk of draughts is also important.
Displacement ventilation systems supply air directly to the occupied zone.The air is supplied at low velocities to cause minimal induction and mixing. This system is used for ventilation and cooling of large high spaces, such as auditorium and atria, where energy may be saved if only the occupied zone is treated rather than trying to control the conditions in the entire space.
