The general types of raised floors in telecommunications data centers include: stringerless, stringered, Stringerless raised floors — an array of pedestals that provide the necessary height for routing cables and also serve to support each corner of the floor panels. Stringered raised floors — a vertical array of steel pedestal assemblies (steel base plate, tubular upright, and a head) uniformly spaced on 2-foot centers and mechanically fastened to the concrete floor.
Cooling load implications Raised Floor The installation of a raised floor system can change the thermal behavior of the building by reducing the interaction between the heat gains and the thermally massive concrete slab. The raised floor serves as a separation between the room and the slab. Energy simulations of an office building located in San Francisco showed that the mere presence of the raised floor affects the zone cooling load profile and tends to increase the peak cooling load. When carpeting is present the negative impact of the raised floor on zone peak cooling load may be reduced.
Raised Floor In the U.S., underfloor air distribution is becoming a more common way to cool a building by using the void below the raised floor as a plenum chamber to distribute conditioned air, which has been done in Europe since the 1970s. In data centers, isolated air-conditioning zones are often associated with raised floors. Perforated tiles are traditionally placed beneath computer systems to direct conditioned air directly to them. In turn, the computing equipment is often designed to draw cooling air from below and exhaust into the room. An air conditioning unit then draws air from the room, cools it, and forces it beneath the raised floor, completing the cycle.
Floating floors are one of the requirements for the THX high-fidelity sound reproduction standard for movie theaters, screening rooms, home theaters, computer speakers, gaming consoles, and car audio systems. While floating floors add to the appeal of a home, they are not recommended for areas that may get wet, i.e. bathrooms and near exterior doors.
