SMARTEMP Auditorium Displacement Diffuser ADS-FD
Smarter Design / Smarter Engineering / SMARTAIR DIFFUSION™
The SMARTEMP Auditorium Displacement Diffuser, type ADS-FD, is a step displacement diffuser suitable for location in the vertical face of auditorium steps or staircase beneath seating. The rectangular diffuser face may be flanged or flangeless. A low velocity, slightly upward inclined, low turbulence airflow pattern is discharged from a perforated face, which is made of powder coated galvanised steel.
Displacement airflow oozes from the perforated step face with minimal mixing to produce a low velocity, low level lake of high quality air that floods the floor around each seat. The slightly inclined discharge pattern minimises air velocities in the ankle regions of seated occupant, to prevent draughts. A low level occupancy microclimate of enhanced indoor air quality is created, in which convective currents from occupants and other heat sources rise upwards in thermal displacement plumes. Heat and contaminants stratify at a high level in concentrated form, where they are removed from the space. Replenishment air is drawn by convection from the low level lake, enveloping heat sources in cool, high quality air.
Due to stratification of heat, relatively large supply-to-return temperature differentials are achievable – dependent on ceiling height – despite the relatively high supply air temperature (typically 19°C), thereby minimising fan energy. Energy savings also accrue from the extended free cooling range typically achieved by the elevated supply air temperature, as well as from the potential to reduce outdoor airflow rates due to the enhanced indoor air quality achieved by the improved ventilation effectiveness of the low level step displacement supply.
