4 Registers for spiral ducts RGS-3 Dimensions 5 The RGS-3 is a supply/return register with adjustable double deflection blades and a volume damper designed specifically for direct mounting on a spiral duct. The use of rectangular register taps are not required. The register is designed in such a way that the flanges always meet flush to the duct regardless of the duct diameter. The RGS-3 comes equipped with end caps and gasketing material around the neck of the register. This prevents air leakage. The RGS-3 is manufactured from galvanized sheet steel and is assembled without the use of welding. This allows the register to be used without further surface treatment and gives it the same finish as the duct. Materials and finish Register: galvanized sheet steel Damper: electro-galvanized sheet steel Maintenance The grille should be removed to gain access to the duct.

15 Ventiduct VSR 16 Ød Ød 1 Dimensions Ventiduct is an air distribution system consisting of spiral ducts enhanced by a number of small nozzles carefully placed into the duct wall. VSR can be ordered with various nozzle patterns for specifi c demands. Large cooling effect Large dynamic range Large induction rate Short throw Discrete diffuser design Easy to install Supplied in fi ve sizes ranging from 8", 10", 12", 16", 20" Ø Available in lengths between 12" to 60" Standard G90 construction Optional: epoxy-coated Ød Ød 1 inch inch Nozzle Pattern 300 Code Order example VSR Product Diameter Nozzle pattern Length Finish (0=Galvanized, 1=Epoxy coated) X

16 Ventiduct VSR Dispersal patterns With Ventiduct nozzle ducts, various fl ow conditions can be achieved in the room. The downward supply of air always creates the greatest air velocities in the occupied zone and is therefore used mostly in industrial ventilation. The choice between air being supplied horizontally or upwards depends on the required form of fl ow. 17 Upward supply air When cooled air is supplied upwards, the cool air mixes with the warmer room air close to the duct nozzles. The supplied air typically covers a vertical area of 78" to 158" below the ducts. At greater distances between the ducts, the supplied air fl ows behind in a displacement fl ow further out in the room. Depending on the required volume fl ow, a nozzle pattern of between 90 and 300 is used. Downward supply air When air is supplied downwards, the air velocities in the occupied zone are increased by the thermal forces (by cooling) and by the dynamic forces (Supplied air velocity). This can result in quite high air velocities in the occupied zone, which is not acceptable for traditional comfort ventilation. However, high air velocities can be recommended if a stable downward fl ow of air is required, and if increased, air velocities in the occupied zone are acceptable. This could, for example, be desirable for industrial applications. A nozzle pattern between 90 and 300 is used, depending on the volume fl ow required. Horizontal supply air When air is supplied horizontally, air jets are formed, creating a mixed fl ow in the room. Depending on the various parameters, maximum air velocities occur in the occupied zone due to the thermal load, air jet velocities or a combination of both. When low supply air velocities are being used (low volume fl ow or large ducts/nozzle patterns) the form of the fl ow approximates a form of low impulse supply air, as with upwards supply air. Horizontal supply air can be used in locations where there is a deliberate demand for a fl ow of air throughout the room in accordance with the mixing principle, and therefore where an upward supply is not being used. Recommended working areas for Ventiduct The values stated are for guidance only and should be used with care, as incoming volume fl ow, cooling temperature, duct design and air pattern all have a great deal of infl uence on the resulting air velocity in the occupied zone. For more detailed calculations, Lindab will be happy to perform a computer calculation. Air pattern Up Down Horizontal Installation height [in] * Min. distance from ceiling [in] ** Δt (t1 - tr) [K] * Distance from fl oor to lower edge of duct ** Distance from upper edge of duct to ceiling must be maintained to avoid dirtying the ceiling

17 Ventiduct VSR Technical data 18 Examples of duct design Ventiduct nozzle ducts can be installed in various ways. In high-ceilinged rooms it is generally an advantage to install Ventiduct nozzle ducts as low down as possible (min. height above fl oor 96"). This provides the greatest effi ciency. Cactus model This solution is used for long, narrow rooms. Exchange model Fishbone model Fork model An ideal solution for long, narrow Ventiduct nozzle ducts stretch out Here the Ventiduct nozzle ducts are rooms. This model provides an even from both sides of the main duct. It is positioned on one side of a main or distribution of supplied air. recommended that a volume damper branch duct. It is recommended that a be used for accurate regulation of the volume damper be installed on the duct air volume. joins in order to ensure consistent air distribution in the duct system. Line model A simple solution that makes duct installation easier and minimizes the number of volume dampers. The distance between the connection ducts is equivalent to twice Ventiduct s maximum length plus the two blind pieces. 20' max total duct length

18 Ventiduct Technical data Building-in distance Ventiducts should not be positioned too close to dampers, elbows, tees or other elements that may create turbulence and hence noise. Straight duct sections should be installed between the Ventiducts and potentially disruptive components, as shown in the illustration below. Suitable duct sections are available. Min. 2 x d Min. 3 x d Min. 4 x d Air velocity in the occupied zone VSR The air velocity in the occupied zone is a result of air jet velocities and thermal air movements in the room. An exact calculation of the resulting air velocity in the occupied zone can be performed using a computer program. (Contact the Lindab sales department for futher information). For upward supply, the maximum air velocity in the occupied zone are dependent on the temperature difference ti-tr. The best results are achieved by using maximum supply air per duct foot, according to the table on the left. Depending on the thermal load (W/ft 2 ) and the duct length, the maximum air velocity in the occupied zone is indicated as a rough estimate in the diagram below. Diagram only applies to upward dispersal pattern with maximum volume flow per duct foot: (distance to ceiling > 4 Ø d). 19 Mounting Min. 4 x d Assembly The Ventiducts are individually packed in cardboard boxes at the factory, to minimize the risk of transport damage. The packaging is numbered to ensure that the ducts are mounted in the correct order, so that the spiral seam is continuous. in/s Distance between ducts (ft) W/ft Please contact Lindab s sales department for further information. 118" Maximum distance between suspension loops is 118"

25 Formo diffusers 26 Lindab Formo Mixed ventilation is the most used principle of ventilation there is. Mixed ventilation is typically used in offices and similar rooms, where you wish to maintain low velocities in the occupied zone as well as low temperature gradients from floor to ceiling. The best results with mixed ventilation is obtained by spreading the air over the entire ceiling area, so that the velocity can subside as much as possible before reaching the occupied zone. There is a large selection of ceiling diffusers in different designs and with different functions, which can be the used depending on the room s dimensions. Functionality Formo mixed ventilation diffusers are known by the diffusers being suspended from the ceiling with a single slot around the diffusers. The diffusers are offered in round or square designs with interchangable perforated or plain faceplates. The diffusers have a very high capacity and are available with several different types of accessories. On the next few pages, is illustrated a combination overview which will provide for a good insight to the series.
