METHOD FOR IMPROVING THE VENTILATION EFFECTIVENESS OF LARGE CONDITIONED AIR PLENUM ENVIRONMENTS INCLUDING SUCH ENVIRONMENTS IN MULTILEVEL RAISED FLOOR ELECTRO-MECHANICAL DISTRIBUTION SYSTEMS

摘要

The present invention is intended for use in large conditioned air plenum environments and particularly in the plenum environment of multilevel raised floor electro-mechanical distribution systems. The invention comprises the step of providing at least one height change of dedicated conditioned air plenum, which alters the plenum's volume. This makes it possible to maintain the preferred static pressure and velocity for conditioned air throughout the entire plenum even as the amount of air in the plenum decreases as conditioned air discharges into the intended space outside of the plenum.
