Description The DF-47 long-throw rectangular diffuser is manufactured entirely of anodised aluminium with a natural finish. The diffuser is composed of a drum allowing the unit to be swiveled, thereby permitting the inlet airflow to be vertically positioned at an angle of ±20º. The unit is also equipped with deflecting blades for distributing the air in horizontal fan-shape or concentrating the inlet airflow in the desired direction. Application These long-throw, high-flow diffusers are particularly useful when the air jet should reach some distance or should be fanned out. They are specially recommended for sport centres, industrial warehouses, clean rooms, recording studios, discotheques, large premises, etc. Dimensions and mounting The dimensions correspond to the size of the opening. The diffuser is always screw-mounted, either directly to the surface or using the MM-47 mounting frame. Also available are 29-0-47 adjustment assemblies that can be accessed with a screwdriver from the front of the diffuser. See dimension tables on page 3. Identification The diffusers can be manually adjusted to adapt the inlet airflow to the needs of the room. The AE model is equipped with a motor that changes the direction of the air (up or down) for use with cold or hot air (summer or winter); this motor may be proportional or on-off (two positions).

DF-49 long-throw nozzle

Description The DF-49 combines long-throw efficiency with a more harmonious design. The stylised lines of the nozzles and the possibility of matching current decorative styles make these diffusers a reliable, great-looking component for facilities with more stringent requirements in terms of design and comfort. Interior architecture are increasingly designing larger spaces for hotels, shopping malls, salons, convention centres, airport vestibules, passenger stations, social halls, etc. In addition to effective air blowing at a long distance through nozzles (originally designed for industrial facilities), the use of these terminal units in more comfortable surroundings requires utmost attention to the aesthetic design. The DF-49 long-throw nozzle and the decorative ring are manufactured in aluminium, with a standard paint finish in RAL 9010 white. The connection part is manufactured of galvanised steel sheet. The DF-49 nozzle has an extraordinarily good aesthetic design and can be painted by special order to fit any decorative need. Application The DF-49 nozzles provide long throws with a low noise level, releasing a long air jet with exceptional precision to a length of over 30 metres. They can be used for spot cooling and are especially appropriate for large rooms requiring a decorative look, for instance, large vestibules, nightclubs or entertainment areas, department stores, hotels, etc. The configuration allows the nozzle to swivel in all directions up to a maximum of ±30° in the horizontal or vertical direction. Dimensions and mounting The diffusers are attached by screws that are hidden by the decorative ring. See page 3. Identification Five sizes with manual swiveling. The motor drive swivels the nozzle in the vertical direction (up and down) at an angle of approximately ± 30°. For motor-driven operation one motor is required per nozzle, even in assemblies containing several units.

Dimensions Version A of the DF-49 jet nozzles can be mounted directly to the duct, plenum box or surface. Version B allows a flexible duct of standard dimensions to be coupled directly to each nozzle. In both cases, the nozzles are fixed by screws, which are housed below a decorative ring which can be removed by simple pressure. In terms of the motor drive system, the motor may be placed inside or outside the unit, depending on the connection system and motor type (each case should be analysed separately).

Selection - DF-49 quick selection table (page 4) Based on the sound power limit, size 16 is preselected. - DF-49-7 chart (page 13) Using size 16 for 400 l/s, the following values are obtained: - ∆Pt = 54 Pa (pressure drop) - LwA = 34 dB(A) (sound power level) - DF-49-2 chart (page 6) For a supply angle of αX= +15° C, The throw will be I=L/cos 15°=12/0,966=12,42 m According to the chart, the velocity for this throw is VX=1,2 m/s - DF-49-3.4 chart (page 11) The impact point under isothermal conditions would be H+HC=H+(L x tan 15°)=4+(12x0,268)=7,2 m The chart indicates that for ∆Τ0 = -10° C, throw: 12,42 m and Q: 400 l/s the vertical deviation is Y = 1,6 m,

as the air jet is non-isothermal. Therefore, the air jets have an impact point situation at a height from the floor of: 7,2-1,6=5,6 m. - DF-49-4 chart (page 12)

For a height HR=5,6-2=3,6m, entering with VX=1,2 m/s gives a velocity of VHR=VH=0,17 m/s in the occupied area. - DF-49-6 chart (page 13) For a throw of I+HR=12,42+3,6=16,02 we have qx/qo=21,9. - DF-49-5 chart (page 12) For a throw of I+HR=12,42+3,6=16,02 we have ∆TX/∆T0=0,07. Therefore, the temperature of the air jet at its inlet in the occupied zone will be: ∆TX=TX-TTemperature TX=TTemperature+∆TX=25+[0,07x(-10)] TX= 24,3° C

Description The new DF-49-ROT combines long-throw efficiency with a more harmonious design, the novelty in this model relative to the nozzle DF49 is the inclusion of a rotational element that reduces air jet for applications where you need shorter throw. The stylised lines of the nozzles and the possibility of matching current decorative styles make these diffusers a reliable, great-looking component for facilities with more stringent requirements in terms of design and comfort. In addition to effective air blowing at a long distance through nozzles (originally designed for industrial facilities), the use of these terminal units in more comfortable surroundings requires utmost attention to the aesthetic design. Interior architecture are increasingly designing larger spaces for hotels, shopping malls, salons, convention centres, airport vestibules, passenger stations, social halls, etc. The DF-49-ROT long-throw nozzle and the decorative ring are manufactured in aluminium, with a standard paint finish in RAL 9010 white. The fixed blade swirl element and the connection part is manufactured of galvanised steel sheet. The DF-49-ROT nozzle has an extraordinarily good aesthetic design and can be painted by special order to fit any decorative need. Application The DF-49-ROT nozzles provide medium throws with a low noise level, releasing a long air jet with exceptional precision to a length of over 20 metres. They can be used for spot cooling and are especially appropriate for large rooms requiring a decorative look, for instance, large vestibules, nightclubs or entertainment areas, department stores, hotels, etc. The configuration allows the nozzle to swivel in all directions up to a maximum of ±30° in the horizontal or vertical direction, the angle of rotation can be determined in steps of 5° adapting specifically to the needs of each installation. Identification Five sizes with manual swiveling. The motor drive swivels the nozzle in the vertical direction (up and down) at an angle of approximately ± 30°. For motor-driven operation one motor is required per nozzle, even in assemblies containing several units. There is also the possibility of thermo-adjustable version.

Initial data Two DF-89 nozzles are located, one in front of the other at a distance of 24 m, with the following starting data based on the sketch attached in the Symbols section on page 16. - L = 12 m - H = 4 m (height from floor) - Qnozzle = 400 l/s - Supply temperature = 15° C - Room temperature = 25° C - ∆T0 = -10° C - HH = 2 m (height of occupied area) The diffuser should be selected to obtain the following: - Maximum velocity in the occupied area: 0,2 m/s. - The vertical temperature gradient must not exceed 3 ºC. - The sound power level of the selected equipment must not exceed 40 dB(A).

14 DF-89

Selection - DF-89 quick selection table (page 4) Based on the sound power limit, size 16 is preselected. - DF-89-7 chart (page 13) Using size 16 for 400 l/s, the following values are obtained: - ∆Pt = 54 Pa (pressure drop) - LwA = 34 dB(A) (sound power level) - DF-89-2 chart (page 6) For a supply angle of αX= +15° C, The throw will be I=L/cos 15°=12/0,966=12,42 m According to the chart, the velocity for this throw is VX=1,2 m/s - DF-89-3.4 chart (page 11) The impact point under isothermal conditions would be H+HC=H+(L x tan 15°)=4+(12x0,268)=7,2 m The chart indicates that for ∆Τ0 = -10° C, throw: 12,42 m and Q: 400 l/s the vertical deviation is Y = 1,6 m,

as the air jet is non-isothermal. Therefore, the air jets have an impact point situation at a height from the floor of: 7,2-1,6=5,6 m. - DF-89-4 chart (page 12)

For a height HR=5,6-2=3,6m, entering with VX=1,2 m/s gives a velocity of VHR=VH=0,17 m/s in the occupied area. - DF-89-6 chart (page 13) For a throw of I+HR=12,42+3,6=16,02 we have qx/qo=21,9. - DF-89-5 chart (page 12) For a throw of I+HR=12,42+3,6=16,02 we have ∆TX/∆T0=0,07. Therefore, the temperature of the air jet at its inlet in the occupied zone will be: ∆TX=TX-TTemperature TX=TTemperature+∆TX=25+[0,07x(-10)] TX= 24,3° C

DIMENSIONS IN mm.

Description DGV round, variable-geometry diffuser constructed of steel plate. The standard finish is RAL 9010 white paint. By special order, the diffuser can be painted in any RAL colour. Operation The DGV diffuser is composed of two concentric modules. The inner module is moveable, and can be moved manually or by a servo drive. This sliding inner module was designed such that, when moved, it simply and efficiently changes the direction of the outlet airflow. The flow direction may be horizontal (for cold air) or vertical (for hot air) as well as any intermediate position, allowing the operation to be precisely adjusted to meet the necessary requirements. Applications The DGV variable-geometry diffusers are perfectly adaptable to industrial applications as well as areas requiring more comfortable conditions, and can be installed at heights of up to 15 metres (in drop and suspended ceilings). The variation in the air direction for cold or hot air (either manually or automatically with a servo drive or thermoadjustable) makes these units particularly suitable for the air conditioning of large spaces such as large vestibules, sport centres, industrial warehouses, airports, entertainment areas, etc. Dimensions and operation The attached table lists the overall dimensions of the diffusers. The overall dimensions of diffuser-plenum box assembly are also shown on page 4. Identification The code allows the various sizes and models of the DGV diffusers to be identified. The servo drive can be accessed through the diffuser, preventing the need for access through the drop ceiling. The plenum boxes contains several suspension tabs. By special order, the plenum boxes contain internal insulation.

Round, variable-geometry diffuser series.

General information

- The DGV-type diffusers have a variable geometry and were designed to meet the air conditioning needs of areas which, depending on the thermal loads during the various seasons of the year, require cold or hot isothermal air. By changing the positioning of an internal device, the direction of the outlet airflow is changed, thereby achieving a horizontal or vertical throw, as well as adjustment within several intermediate positions. - The DGV-type diffuser was designed by the Research & Development Department of KOOLAIR, S.A., and tested and calibrated in our own Distribution and Acoustic Laboratory, which is equipped with the most advanced control and measurement systems. The most advanced theories on air diffusion in rooms have been used in its application, based on experiments and studies performed at the KOOLAIR laboratory in Spain.

Step 1. Quick selection tips for the model Based on the flow rate and the distance, Hdiff, from the diffuser supply outlet to the floor, the 250 or 315 models can be chosen.

Step 2. Verification by noise level and pressure drop. The data are obtained from the flow rate and the diffuser model.

Comparison Thus, the charts indicate that the selected diffuser is DGV 315. Step 3. Determination of the temperature correction factor (Cy). It is necessary to know if the diffuser throw is within the operating limits. The next step (nº4) , is used to determine if the diffuser (in terms of throw) meets the needs required. This is determined by the temperature differenc ∆T (°C) and the maximum velocity in the occupied area. Vz (m/s), both specified in the conditions of the selection in the sample project.

In this case, the factor «Cy» = 0,8 Step 4. Verification of throw within the operating limits. «Ac», is obtained from the following equation: Ac = [(Hdif - Hzo) / Cy ]+ Hzo Ac = [(6 - 1,8) / 0,8 ]+ 1,8 = 7,05 m

8 Series DGV

Once the value of «Ac», is determined, the following figure shows that the diffuser is within the operating limits (within the minimum and maximum lines). Likewise, it allows us to find the stroke (in mm) of the servo motor shaft that will keep the central core fixed at a convenient height, in order to ensure the performance for which it has been selected.

Step 5. Determination of the correction factor to calculate the minimum distance between diffusers. This factor is known as Ca. and is obtained from the following chart, using the air flow per diffuser (Q m3/h) and the maximum velocity in the occupied area (Vz m/s).

Series DGV 9

Where the factor Ca = 3.8 from the following equation, yielding the following minimum distance, A, between diffusers: A = Ca / (Hdif - H zo) A = 3,8 / (6 - 1,8) A = 0,9 m As in the selection example, the projected distance between diffusers, A, is 5 m and the minimum distance recommended by the chart is 0.9 m. Therefore, the selection is correct. Conclusion Diffuser selected: DGV-315 Air flow rate: 800 m3/h Pressure loss: 24 Pa Sound power: 38 dB (A) Temperature difference ∆T: 15°C Maximum velocity in occupied area: 0,25 m/s. Stroke of the electrical servo drive: 50 mm.

Adjustable blade variable geometry diffuser DVP

Description The adjustable blade variable geometry diffuser Model DVP provides an optimum discharge in cooling (horizontal discharge) and heating (vertical discharge) enabling the diffuser to meet the required comfort criteria .by moving its blades The diffuser is available in 9 sizes ranging from Ø160 mm to Ø 800 mm in manually version and 6 sizes from Ø250 mm to Ø630 mm either motorised or thermo-adjustable versions Operation The adjustable blade variable geometry diffuser allows the air discharge horizontal, inclined and vertical by moving its blades. This movement can be carried out manually, by an electric motor or by a thermal element which positions the blades depending on the supply air temperature Application DVP diffusers should ideally be mounted at heights in excess of 3.5 m for supplying cooled, isothermal and heated air. This diffuser is an ideal choice for high ceilings applications in areas such as airports, factories and public buildings due to its high aesthetic appeal, ease of installation, regulation, and high air volume capacity Dimensions DVP is available in 9 sizes which are shows on page 63, both overall dimensions as the set of plenum plus diffuser. There are three models, DVP, movement of blades manually, DVP-TR self-adjusting blade moving through the a thermal element, and movement by electric motor, DVP-M. Finishes The outer ring and the blades are made of steel sheet. Standard finish - painted RAL 9010, other colours are available upon request. Plenum boxes to suit are also available. Identification The code allows the various sizes and models of the DVP diffusers to be identified. The thermo-adjustable and motorised versions are from Ø 250 mm to Ø800 mm sizes. The servo drive can be accessed through the duct. The plenum boxes contain several suspension tabs. By special order, the plenum boxes can be supplied with internal insulation.

Dimesions

The DVP-type diffusers have a variable geometry and were designed to meet the air conditioning needs of areas which, depending on the thermal loads during the various seasons of the year, require cold or hot isothermal air. By changing the positioning of its blades, the direction of the outlet airflow is changed, thereby achieving a horizontal or vertical throw, as well as adjustment within several intermediate positions. - The DVP-type diffuser was designed by the Research & Development Department of KOOLAIR, S.A., and tested and calibrated in our own Distribution and Acoustic Laboratory, which is equipped with the most advanced control and measurement systems. The most advanced theories on air diffusion in rooms have been used in its application, based on experiments and studies performed at the KOOLAIR laboratory in Spain. Here are three versions available of the diffuser, DVP (manual movement of blades), DVP-M (movement of the blades by electric motor) and DVP-TR (movement of the blades through the action of a thermal element).

4 Multinozzle Diffuser

INTRODUCTION

Due to the growing demand in the market for buildinglarge spaces in hotels, shopping malls, theatres, etc., wehave developed a diffuser which is able to combine designand efficiency.

The long range offered by the DF49MT3 multinozzlediffusers coupled with their low noise level and their aestheticsmake this diffuser a benchmark in the current marketplace.

DESCRIPTION

The long-range multinozzle diffusers of the DF49MT3series comprise a rectangular faceplate in steel sheet where3 to 10 nozzles can be incorporated per row in a maximumof 3 rows in a standard execution. The nozzles aremanufactured in ABS, class V1 material, according to UL 94standars.

There are several types of construction; on a platewithout a frame or on a plate with a frame, which can bemounted on both the wall and the ceiling .

There is also a model which can be adapted to differentduct diameters for a maximum of 2 rows of nozzles in astandard execution.

These diffusers can be finished in black (Ral 9005) orin white (Ral 9010).

The diffuser can be fixed by using either screws or amounting frame. If you decide to fix it to the wall or a plasterceiling with screws, it is also advisable to use a mountingframe so that the plaster is not damaged.

APPLICATIONS

The multinozzle diffusers of the DF49MT3 series allowlong ranges of air to be obtained with a low noise level. Theyare designed to air-condition shopping-malls, museums,theatres, cinemas, large halls, etc.

The shape of the nozzles allows them to be pointedseparately, in all directions, up to a maximum of 30O.

All the different models can have a removable plenumfitted.

The graphs which are shown bellow all correspond to 1 row of nozzles. If you would like to make a study of 2 or 3rows, you must choose the air flow volume corresponding to 1 row and then apply the correction quotients which appearon the respective tables which are shown with the graphs.

For example, if we have an air flow volume of 1000 m3/h and we want to install a 2-row multinozzle diffuser, on thegraph we must select an air flow volume of 500 m3/h (the volume which would correspond to one row) and apply thecorresponding correction quotient, in this case 3, fron which we can deduce that the noise output would be 36,8 dB(A).

Example of selection

Input data:

L = 15 mH = 6 m (Height of location above the floor)Q

MULTINOZZLE =

500 m3/h

Supply temperature = 19 OCAmbient temperature = 25 OCΔT

O = - 6 OC

HH = 1,8 m (Height of the habitability area)

We must make a selection in order to obtain:

- A maximum speed in the habitability area of 0,2 m/s.- The vertical temperature gradient must not exceed 3 OC.- The noise output level must not exceed 35 dB(A).

Selection:

With the air flow volume we have and on the basis of the noise output limit, on the quick selection table we obtain amultinozzle diffuser of 1 row with 8 nozzles per row.

With graph 1, showing load loss and noise output level, we obtain:

ΔPEst

= 106 Pa (Load loss)L

WA = 33,8 dB(A) (Noise output level)

In graph 3 showing the speed of the air jet in the range, we take a discharge angle α = 0O, and thus we have:The range will be I = L/cos 0O = 15/1 = 15 m

looking at the graph, the speed corresponding to this range is VX = 0,48 m/s

Due to the thermal step (we are supplying cold air), a deviation in the air jet occurs. Looking at graph 4, the impactpoint in isothermal conditions would be:

H + HC = H + (L x tan 0O) = 6 + (15 x 0) = 6 m

Fron the graph, we also get that for a ΔTO

= - 6 OC, a range of 15 m and a volume of Q = 500 m3/h, the verticaldeviation for being a non-isothermal air jet is Y = 2,6 m

Therefore, the air jet impact point occurs at a height above the floor of: 6 - 2,6 = 3,4 m

On the air flow speed graph, (graph 5), for a height of HR = 3,4 - 1,8 = 1,6 m, using V

X = 0,48 m/s, our result is that

the speed in the habitability area will be VHR

= VH = 0,15 m/s.

Graph 6 or the induction graph gives us, for a range of I + HR = 15 + 1,6 = 16,6, un qX/q

O = 63,3

Using graph 7 or the temperature quotient graph, we can see that ΔTX / ΔT

O = 0,026, therefore, the temperature of the

air jet on entering the habitability area will be:

ΔTX = T

X - T

AMBIENT

TX = T

AMBIENT + ΔT

X = 25 + [ 0,026 x (- 6) ] = 24,84 OC

DF-47-NARROW

DF-47-NARROW (-S) high induction linear diffuser for medium-to-long throw

DescriptionHigh induction linear diffuser for medium-to-long throw, DF-47-Narrow model, with length L mm and slot H mm for air flow.Allows ±30º vertical turn of core (linear nozzle), due to a narrow slot that makes it possible to cover medium and long throws, achieving comfort with both cooling and heating and providing an excellent aesthetics.They are suitable for both ceiling and wall installation. Particularly appropriate for variable air volume, although the design allows excellent operation with constant air volume as well.

ApplicationThese medium-to-long throw diffusers are very appropriate in cases that require a long-distance air jet or a medium-distance air jet with low sound levels.They are especially indicated for commercial facilities, mezzanines, shops, residences, etc.This diffuser is suitable for both supply and return. High-quality aesthetics and performance are further enhanced by alternating the return diffusers with supply diffusers in the same continuous line.

FinishesManufactured entirely of extruded aluminium sections.The unit can include a directional (29-O), directional blades (G) (not available in slot size 15) volume control damper and plenum box of galvanized steel sheet (internally insulated (-PFA) or uninsulated (-PF)). There are two types of plenum box: fixed or detachable.If a plenum box is included, a volume control damper can be included in the connection inlet, annulling the 29-O damper.

In the DF-47-Narrow-IC and DF-47-Narrow-CC models, the frame or duct is constructed of galvanized steel and the diffuser is made of aluminium.

Standard finish in anodized or painted in RAL-9010 glossy white.

Operating mechanisms and mountingThe mounting systems available for the diffuser element are shown in detail on page 5.The diffuser is specified by the slot length and slot width. The -MT motor-driven mechanism moves the nozzle in the vertical direction (up and down) at an angle of approximately ± 30°. The required motorization is provided by one motor per diffuser, even in groups containing several units. Thermal self-adjustment is also possible.
