1.1 INTRODUCTION
The QLCI displacement induction ventilation diffusers are designed
to provide air quality and acoustical performance similar to
conventional displacement systems but are designed specifically for
the North American climate. Units are fitted with a series of air
induction nozzles that allow the supply of conventional air (50° to
55°F) to the terminal. These nozzles induce room air through a
cooling and/or reheat hydronic coil to pre-condition the air prior to
mixing with the primary nozzles. The result is a constant volume
(variable temperature) displacement type supply of air to the space.
The QLCI displacement induction ventilation diffusers, when applied
with optional rear fin tube heating elements, delivers warm air to the
space along the exterior wall or large window exposures. Room air
migrates through air pathways to the fin tube elements and the
heated air travels upward due to radiation or buoyant heat
forces. No primary air is used to drive air upward across the fin tube
heating elements. Ventilation air from the central station air handler,
coupled with induced room air provides the necessary ventilation
requirements and total airflow to the space via the lower face diffuser
panel outlets.
The integral hydronic coil within the unit is sized to allow the QLCI
terminal to condition the room while the central system air handler
supplies air at (or near) the mandated space ventilation rate.
Therefore, the central station air handler can supply 100% outside
air while all of the return air from the space is exhausted.
The diffuser uses the primary air energy to induce air through the
hydronic coil and does not contain any moving parts such as, fans,
motors, or compressors to be maintained.
