Linear diffusers
KL Series
Overview
The KL series diffusers represent the best development for this type
of air diffusion units.
Their particular structure allows to direct the flow of injected air
along the ceiling. The effect is one of a progressive mix with the air
in the room without the need of creating air currents or air vortexes
that may be perceptible even in cooling mode. In contrast it is possible
to direct the flow of injected air rapidly towards the floor, with a
large forcing action to obtain a rapid heating of the room.
The modular structure allows for an unlimited number of rows, parallel
slots, without any visible joint line showing.
The KL series diffusers stand out thanks to their innovative design,
characterised by its soft lines and curved edges, not purely for
aesthetic value. It is a result of accurate fluid dynamic studies,
carried out using innovative mathematic models, aimed at optimizing the
distribution of the speed of air exiting the diffuser.
The KL series diffusers are complemented with their own line of plenum
boxes made in such a way that when installing, no particular tools or
accessories are required for the job.

Air flow regulation
horizontal flow
The slow follows the line of the ceiling
Guaranties the total absence of air currents
both in heating and cooling.
|
|
verticalflow
The flow penetrates the room directly
Prevents thfor lengths greater or euqal to1500mm
used for heating.

Test Method
The analysis of the aeraulic performances of the KLV series diffusers have
been carried out by means of a "virtual test laboratory".
All the tests and the relative measurements have been conducted by means of
an advanced CFD (Computational Fluid Dynamics) software.
This applies the method of the finished elements to the fluid dynamic for the
analysis of speeds, air flow distribution and pressures losses.
cooling conditions
deflectors angled for horizontal flow
The Values of flow length of each diffuser have been defined in isothermal
conditions in accordance with ISO 5219 regulation with deflectors angled in "cooling"
position, for horizontal flow.
The length of the flow is indicated by values obtained from the speed along the
trajectory of the air vain.
cooling conditions
joining of flows
An analysis has also been carried out of the intersection of the flow of two
diffusers with equal flow rate placed opposite at a distance of 4.5 meters. In
this case the obtained results show the air speed of the intermediate zone
between the two diffusers at different heights.
