raised floor

An elevated floor used in datacenters and laboratory facilities that allows wires to be run underneath. A raised floor is also used to distribute cooling. There are many varieties; however, the traditional raised floor uses square tiles over an aluminum grid that creates a plenum (space) several inches above the actual floor. Each tile can typically be lifted up and out for access to the cables below. Although raised floors are commonly used for datacenter cooling, a unique alternative eliminates the raised floor (see KyotoCooling).


The Traditional Raised Floor
This type of raised floor has been the standard in datacenters for decades. The structural grid is spread out over the original floor, which allows flexibility in the initial equipment installation as well as future changes. (Image courtesy of Imprint Data Center Solutions, www.imprintdcs.com)

A floor fabricated entirely of square plates that rest on interlocked pedestals attached to the structural floor of a building. The plates usually are fabricated of aluminum and are covered with cork, carpet, or vinyl tiles. The plates can be removed to provide convenient access to the cables beneath; used extensively in computer rooms.

The Liebert DS precision cooling system is available in configurations of 53 kW, 70 kW, 77 kW and 105 kW to support applications that require cooling delivered from the top of the unit in data centers or telecommunications environments that do not have a raised floor. The Liebert DS features digital scroll compressors, which allow unit capacities to adapt to changing room conditions as small as 1[degrees]F and 1 percent relative humidity.
