LINEAR SLOT DIFFUSERS WITH DEFLECTORS KM-G

KM-F SERIESOVERVIEW

CHARACTERISTICS APPLICATIONS

OVERVIEW :The KM-F series adjustable multidirectional linearaluminium diffusers represent a tested solution of airdiffusion. The direction of the air exiting the diffuser isregulated and controlled by means of a central bladeplaced inside each slot. this solution allows to preciselyadjust in the easiest way possible the horizontal andvertical direction of the flow of air.The KM-F series has be realised to be installed withoutthe use of visible screws.These diffusers are assembled with up to 4 slots toaccommodate all possible applications.

APPLICATIONS:A diffuser suitable for all civil applications in any airmixing ventilation system for medium height installations,between 2.6 and 6 metres.It allows to heat large spaces or large shopping centregalleries and corridors. The ideal application is close tolarge windows or even glass walls to prevent the forming

FINISH :The KM-F series are made in naturally anodized aluminium.On request they can be supplied with an epoxy finishing on thesurface, white RAL 9010.

MATERIALS : Diffuser in naturally extruded aluminium,deflecting blade in black profile aluminium, blackPolypropylene deflecting blade, plenum in galvanized steel,externally isolated in autoestinguishing Polyethylene, certifiedClass 1.

DAMPER REGULATION : The calibration damper isactioned by a level inside the diffuer.

g g p gof condensation.

FIXING OF DIFFUSER TO THE CEILING :The S2 method of fixing (later explained) is done bymeans of fixing of traction systems between the laterallyfixed supports in the body of the diffuser and the ceiling.With the S3 method, using a traction fixing systembetween the supports fixed directly in the plenum and theceiling.

FIXING OF THE DIFFUSER TO THE PLENUM :The fixing in the S2 system is done by means of laterallyautofilletting screws in the body of the diffuse.In the S3 system by means of fixing bridges.

SERIESOVERVIEW

CHARACTERISTICS APPLICATIONS

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 KLV series diffusers are complemented with their own line of plenum boxes made in such a way that when i lli i l l i i d f

FITTING OF THE DIFFUSER: The KL diffusers are fitted with specific plenums by means of suspension springs or with mounting bridges.This allows for a rapid fitting even after all masonry work has been completed.

FINISH: The KL diffusers are constructed with an anodized or RAL 9010 painted aluminium body with deflecting blades also painted black or white RAL9010.Other special finishes may be provided upon request.

MATERIALS: Diffuser completely in naturally anodized extruded aluminium, plenum from galvanized steel sheet and external insulation in self-extinguishing Class1 material.

VERSIONS : KLV Series: identifiable from the large area that allows to minimise the pressure loss and noise even at elevated air flow

installing, no particular tools or accessories are required for the job.

WORKING CHARACTERISTICS:The KL series diffusers are made of a diffuser body constructed in aluminium, housing the various air expulsion slots and a series of deflecting blades, also in aluminium, for horizontal or vertical orientation flow of the air. The direction may be easily adjusted without the need to remove the diffuser itself.The body of the diffuser may be integrated with a regulation damper having small square holes. This solution has been studied so as to obtain a precise calibration of the quantity of air injected into the room and at the same time, to reduce to a minimum the pressure loss with the damper fully opened.

APPLICATIONS:The KL diffuser series are used in ventilations systems in facilities where the ceiling height is between 3 and 6 meters, such as open space offices, commercial galleries and hospital wards.The achievable air flows vary in relation to the length of the diffuser and the number of slots. The capacities are included between 50m³/h and 120m³/h per meter per slot with temperature grades varying between +15 °C end I –10 °C.

pcapacities.Adjustment can be made to the air flow via a damper in the plenum connector. KLS Series: identifieable by the possibility of installing sliding regulation dampers inside the body of the diffuser to allow adjustment to the air flow individually for each linear slot.

SERIESAIR FLOW REGULATION

CHOICE OF DIRECTION OF THE FLOW:The horizontal flow represents the more common use for this kind of diffuser, both in heating and cooling. The flow stays close to the ceiling and spreads horizontally inside the room. This generates a vertical recall effect of the air already present guarantying the perfect mix without the presence of air currents within the occupied zone.The vertical flow, used when heating, allows to send hot air directly in the occupied zone, contrasting the common tendency of hot air to stratify due the lower density in the higher parts of the room.The change of direction of the flow is obtained turning the deflector blade from inclined to horizontal and vice versa.The blade is adjusted from outside the diffusers with a leaver, at both the extremities of each slot.

SERIESMETHOD OF ANALYSIS

OF PERFORMANCE

Test MethodThe 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.

The dimensions of the virtual room in the test configuration for each single diffuser are:

Width of the test room: br=5.6 mLength of the test room: lr=7.5 mHeight of the test room: hr=3.0 m

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.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.

cooling conditionsjoining of flows

heating conditionsdeflectors angled for vertival flow

g

The values of the depth of penetration have been defined with the deflectors angled in "heating" position with a temperature difference between injected and room temperature of 10 °C. The best possible adherence to real conditions has been followed considering the dissipation of heat throw surfaces of the virtual test room.

The values of pressure loss have been defined in isothermal conditions with deflectors angled both at "heating" and "cooling" positions.

The Ak values (efficient section for the expulsion of the air flow) have been defined in accordance with ISO 5219 regulation.

HIGH AIR FLOW LINEAR SLOT DIFFUSERS KD

SERIESOVERVIEW

CHARACTERISTICS APPLICATIONS

OVERVIEW :The KD series linear diffusers allow to manage high air flows with minimum pressure losses and generated noise power.They allow to fully make us of the induction principle, guaranteeing optimum comfort conditions, no noticeable air currents and temperature uniformity, even in large areas by positioning the diffusers along the perimeter of the ceiling.

CHARACTERISTICS AND OPERATION :The KD series diffusers are constructed from an aluminium diffuser body housing the different exhaust slots and a series of deflector blades, also in aluminium, for the horizontal or vertical air though. The change of direction of the air through can be easily made without removing the diffuser but simply using a supplied tool. The regulation of the air flow can be made by using a butterfly type damper in the plenum connection.

APPLICATIONS : Th KD i diff id l i li i i h ili

DIFFUSER INSTALLATION: The KD series diffusers are installed inside special plenum boxes, by suspension using fixing bridges. This solution allows a quick installation even at the end of work carried out on the building site.

FINISH : The KDA and KDF diffusers are constructed from an aluminium body anodized or painted white RAL 9010 with a black painted deflection blade. The KDP diffusers are constructed from an aluminium body and a carbon steel panel painted RAL 9010 and a black painted deflector blade.Special finishes for the diffuser body can be made on requested.

The KD series diffusers are ideal in application with a ceiling height between 3 and 6 meters like open space offices, commercial galleries hospital wards or hotel rooms.

VERSIONSKDA : standard version for ventilation;KDF: version for supply and extraction with anti-dust filter, ideal for guaranteeing the cleaning of the air in recycle systems;KDP: version installed on steel panel, suitable for installation in modular counter ceilings, used for supply of air.

HIGH AIR FLOW LINEAR SLOT DIFFUSERS KD

SERIESAIR THROW ADJUSTMENT

CHOICE OF AIR THROW ORIENTATION :The horizontal throw represents the most common use of this type of diffuser, both for heating and cooling. The throw follows the ceiling and expands horizontally within the room. This generates a vertical recall of air present in the room, guaranteeing a perfect mixture of air without the presence of air currents within the occupied area.The vertical throw, used when heating, allows to send the hot air directly within the occupied area to hinder the formation of layers of hot air in higher parts of the room caused by the lesser density.The change of orientation of the air throw is obtained by rotating the deflector blade from an inclined position to a horizontal one, and vice versa. The blade is rotated from within the diffuser, with the use of a leaver at both extremities of the air slot.

U08 Diffusion-vers.14.00.xls U08-44

The adjustment of the air throw from horizontal to vertical position is made using the special lever suppliedfollowing the sequence here shown
