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 plenumenvironments and particularly in the plenumenvironment of multilevel raised floor electro-mechanical distributionsystems. The invention comprises the step of providing at leastone height change of dedicated conditioned air plenum, which alters theplenum's volume. This makes it possible to maintain thepreferred static pressure and velocity for conditioned air throughout theentire plenum even as the amount of air in the plenum decreasesas conditioned air discharges into the intended space outside of the plenum.
