UFAD systems use an underfloor supply plenum located between the structural concrete slab and a raised floor system to supply conditioned air to supply outlets (usually floor diffusers), located at or near floor level within the occupied space. Air returns from the room at ceiling level or the maximum allowable height above the occupied zone. [1]
DOAS air handling unit with heat recovery wheel and passive dehumidification. A dedicated outdoor air system (DOAS) is a type of heating, ventilation and air-conditioning system that consists of two parallel systems: a dedicated system for delivering outdoor air ventilation that handles both the latent and sensible loads of conditioning the ventilation air, and a parallel system to handle the ...
These motors are sometimes called DC motors, sometimes EC motors and occasionally DC/EC motors. DC stands for direct current and EC stands for electronically commutated.. DC motors allow the speed of the fans within a fan coil unit to be controlled by means of a 0-10 Volt input control signal to the motor/s, the transformers and speed switches associated with AC fan coils are not required.
the air's density and thus its buoyancy. Air buoyancy changes according to surface temperatures and; forced air movement due to fans and the motion of people and objects in the space. Convective heat transfer with underfloor systems is much greater when the system is operating in a heating rather than cooling mode. [60]
Cellular floor raceways are electrical wiring ducts or cells made from steel floor deck that serve as structural formwork for placement of concrete floor slabs and also as wire and cable raceways within the concrete floor slab.
This lineup configuration is considered to be the most densely populated in terms of square foot area and, therefore, the largest floor load anticipated for a raised floor system. Considering prorated aisle space, a single equipment cabinet will then occupy an 8-square-foot (0.74 m 2 ) floor area (4 sq ft or 0.37 m 2 for the cabinet and 4 sq ft ...

A concrete slab is a common structural element of modern buildings, consisting of a flat, horizontal surface made of cast concrete. Steel- reinforced slabs, typically between 100 and 500 mm thick, are most often used to construct floors and ceilings, while thinner mud slabs may be used for exterior paving ( see below ).
