3 Use Lindab's supply air beam can be used for cooling, heating and ventilation. Water valves, actuators, Regula Secura, Regula Combi and Regula Connect can all be built into the beam. Installation I-0 is installed into a false ceiling, and can be suspended by hangers or threaded rods. As standard is delivered for a 00 x 00 T false ceiling. can also be delivered with a variety of different Clip-in options, making the beam suitable for other types of false ceilings. Worth noting features the Lindab JetCone, an innovative way of regulating the air volume. The air volume can easily be adjusted without having to worry about pressure and noise issues. The Angled Nozzle system secures a perfect air spread pattern, available in a number of factory preset angles. As a plus feature the Lindab AirGuide system offers readjustable air spread pattern control. The chilled beam is fully integratable with the Lindab ehybrid solution and together they provide an optimal energy efficient solution. Lindabs active chilled beams are Eurovent-certified and tested according to EN-.

4 Optimal functions Despite the product's small external dimensions, the construction makes it possible to achieve a high cooling capacity. is Lindab's highest performing supply air beam designed to meet extra high cooling demands. is based on the induction principle. Ventilation air is released through the nozzles into a dispersal zone, thereby creating a low static pressure. The low pressure causes the warm air from the room to be induced into the ventilation air through the battery. The volume of the warm indoor air is two to seven times that of the ventilation air. The air is cooled as it passes through the battery, which consists of aluminium fins with copper pipes filled with cold, running water. The heat from the room is absorbed through the aluminium fins and then transferred through the copper pipe to the water circuit and goes further to a central cooling unit. can be delivered with an exhaust air valve, on request. Air duct Copper pipes Cooled air Warm indoor air Actuators Air duct Copper pipes Detachable faceplate Picture. is based on the induction principle. JetCone and Angled Nozzles The opening size of the nozzles can be adjusted, by operating the adjustment pins in each corner of the beam. The air distribution can also be adjusted, to achieve different amounts of air on either side of the beam, or to achieve an asymmetrical air pattern along the side of the beam. All thanks to our patent pending JetCone system. The Lindab Angled Nozzles system successfully combines the Jetcone air volume adjustment with a preset air spread pattern. The combination of the Jetcone and the Angled Nozzles systems results in reduced throw lengths and optimized air volume regulation. The design is made to secure the coanda effect and a fan-shaped air pattern. The adherence of the air to the beam already occurs at the JetCone opening. Then, due to the coanda effect, the air follows the side of the beam towards the ceiling. Coanda effect Battery
5 Hygiene Everything is accessible for service The faceplate is simple to lower or remove. The faceplate is kept in place by four cotter pins. If two of the cotter pins, on one of the long sides of the faceplate are removed, the faceplate will open and hang from the other two pins. For complete removal, please see the installation instruction. When the faceplate is lowered or removed, the battery is accessible from below (see picture ). Construction is power is Lindab's high performing supply air beam, giving the highest cooling capacity to be used in rooms with substantial cooling requirements. In terms of appearence looks like Premum and can therefore preferable be used in alternation with Premum beams and thus provide an architecturally uniform appearance in the room. is developed and designed to achieve a high degree of flexibility. The standard with Angled Nozzles and JetCone allows the adjustment of air diffusion, air volume and air pressure. The beam equipped with the plus feature Airguide, makes it possible to easily change the air spread pattern. The water pipes are made of copper. Nevertheless, the water should be oxygen-free to prevent corrosion. Picture. When the faceplate is lowered or removed, the battery are accessible from below. AirGuide system is shown in picture (plus feature).
6 Initial settings Adjustment JetCone is delivered as standard with Lindab s JetCone air volume adjustment system. The JetCone System makes a very flexible product with possibility of adjusting air diffusion, air volume and air pressure. Adjustment is made by setting the four adjustment pins into different positions. The adjustment pins can be set in any of the steps, thereby offering a total of 0 different settings. The adjustment is done without any tools, which makes it very fast and easy to adjust the air pattern, air volume and air pressure. The fast adjustment system gives an opportunity within planning, since the product choice can be made in an early stage and the products can be drawn into the planning of the project even though the planner do not have all the data normally required to select a suitable beam. Presetting Angled Nozzles To achieve a desired air spread pattern the beam is delivered with the Angled Nozzles air distribution system. The Angled Nozzles are a simple yet effective way of creating a divergent air spread pattern without the capacity issues normally related to an air deflector system. The Angled Nozzles can be delivered preset in one of the following standard settings: 0 (default setting) 0 In order to meet special demands, the Angled Nozzles can be delivered in other configurations than the ones mentioned above (picture ). For more information, please contact Lindab. NB! Please note that the Angled Nozzles are manufactured in a fixed position (default 0 ) and cannot be retrofitted or changed. Picture.

8 Dimensioning Cooling capacity air P a. Start by calculating the capacity required for the room, to keep a certain temperature. Lindab s TEKNOsim is an excellent tool for this.. Calculate which cooling capacity, or read in diagram, that is supplied by the ventilation air.. Remaining heat load needs to be cooled by the water circuit in. The formula for calculating the capacity of the air: P a = q ma x c pa x t ra Size comparison by t r = C with: q a = Primary air flow rate P a [W] = q a [l/s] x. t ra [K] and P a [W] = q a [m³/h] x 0. t ra [K] Minimum flow Please note that flows below the recommended minimum flow, can result in unwanted air in the water pipes. Exciding the nominal flows is not recommandable as the capacity gains will only be minimal. Pipe diameter Min flow Nominelt mm 0.0 l/s 0.0 l/s mm 0.00 l/s 0.0 l/s Dimensioning Cooling capacity water P w Follow the instructions below to read off the effect from the diagram.. Calculate t rw.. Product length L minus 0. m, to obtain the active length L act.. Divide the primary air flow rate q a by the active length L act. Enter the result on the lower axis of diagram.. Follow the flow line to the right pressure, and then read off the specific cooling capacity P Lt per active metre.. Calculate the temperature difference in water circuit Δt w and find the capacity correction factor e Δtw in diagram.. Multiply the specific cooling capacity P Lt that was read off by e Δtw, t rw and active length L act. Definitions: P a = Cooling capacity air [W] P w = Cooling capacity water [W] P tot = Cooling capacity total [W] q ma = Air mass flow rate [kg/s] q a = Primary air flow rate [l/s] c pa = Specific heat capacity air [,00 kj/kg K] t r = Room air temperature [ C] t wi = Water inlet temperature [ C] t wo = Water outlet temperature [ C] t ra = Temp. diff., room air and primary air temp.

Cooling capacity air P a as function of the primary air flow rate q a. If the air supply flow is l/s and the temperature difference of the room air and the supply air is t ra = K, then the cooling capacity of the air is W.
9 Example Cooling: What is the cooling capacity of a. m with 0 l/s and pressure of 0 Pa? The room s summer temperature is assumed to be t r =.º C The cooling water temperature in/out of the is /º C. Answer: Temperature difference: t rw = t r (t wi + t wo )/ t rw =. - (+) / = K Active length: L act =. m - 0. m =. m q a / L act = 0 l/s /. m = l/(s m) Read off, from diagram : P Lt = W/(m K). Diagram shows a capacity correction factor e Δtw : t w = t wi - t wr = C - C = K e Δtw = 0. Cooling capacity: P w = W/(m K) 0. K. m = W NB! The capacity diagram applies for the nominal water flow of q wnom = 0.0 l/s. To obtain the right cooling capacity P w for other flows, read off the capacity correction factor e qw from diagram, and then multiply the calculated cooling capacity by this factor as shown in example for heating.

10 Dimensioning Capacity correction for water flow e qw Example Heating: What is the heating capacity of a. m with 0 l/s and pressure of 0 Pa? The room winter temperature is assumed to be t r = º C. The hot water temperature in/out of is /º C. Answer: Temperature difference: Δt rw = (t wi + t wo )/ t r Δt rw = (+) / - = 0 K Active length: L act =. m - 0. m =. m q a / L act = 0 l/s /. m = l/(s m) Read off, from diagram : P Lt =.0 W/(m K). Water capacity: P w =.0 0 K. m = W Use the calculated water capacity and calculate the water flow: q w = P w / (c pw x t w ) q w = / (00 x ) = 0. l/s The capacity correction e qw will then be 0. (see diagram ) and the new capacity: P w = x 0. = W. Using the new heating capacity, a new water flow is calculated: q w = / (00 x) = 0.0 l/s Read off the capacity correction e qw at 0. and calculate the capacity: P w = x 0. = W Using the new heating capacity, a new water flow is calculated: q w = / (00 x) = 0.0 l/s Seeing that the flow is near stabile at this point in the calculation, the heating capacity is calculated to be W.
