Does this mean I canât ever say âciao?â Of course the answer to this is no. Youâll hear ciao being said all over Italy â itâs an incredibly common greeting throughout the country. But if youâre paying closer attention, youâll see that itâs almost always used between people who know one another or are in the same peer group.
In building construction, a plenum (pronounced PLEH-nuhm, from Latin meaning full) is a separate space provided for air circulation for heating, ventilation, and air-conditioning (sometimes referred to as HVAC) and typically provided in the space between the structural ceiling and a drop-down ceiling.n buildings with computer installations, the plenum space is often used to house connecting communication cables. Because ordinary cable introduces a toxic hazard in the event of fire, special plenum cabling is required in plenum areas.
It is recommended when the sides of the Plenum Box are exposed and with the following conditions: 1) The make-up air is cooled, or 2) the make-up air is not heated and outside temperatures are cool.Matte faced is the standard insulation.he plenum box shall be capable of delivering up to 150 CFM per lineal ft. of ventilator at a low velocity. The plenum box shall be designed to fit in front of the ventilator, either flush with the ceiling or dropped down in front of the ventilator.
