3 Use Lindab's supply air beam is the lightest supply air beam available on the market. is Capella's sister product; the difference between the two beams is that also uses supply air. is mounted on the ceiling and supplies cooling through natural convection and radiation, which results in a draught-free climate. 35% of the cooling supplied by comes from radiation and the rest from convection. Compared to a conventional beam, provides a significantly higher cooling effect at lower room temperatures. can be provided with the following features: Regula Secura condensation guard, valves and actuators, etc. offers many possibilities and great flexibility; for example, you can have coated in any colour you want. Installation Worth noting is the lightest supply air beam available on the market, a beam 6.0 m long, with a width of 53 cm and a weight of only 28.8 kg. has flat and easily accessible surfaces, which helps maintain a good indoor hygiene. Furthermore, the height of is only mm, which contributes to its great freedom of placement. Lindabs active chilled beams are Eurovent-certified and tested according to EN-116. Key figures Length: Width: Height: Capacity: mm (steps of 0 mm) 170, 350, 530, 600 mm mm 1420 W Calculation setup Room temp: 25 C, Water temp: C, Air temp: 18 C, Nozzle air pressure: 80 Pa, Air flow: l/s/m is installed either suspended or recessed in a ceiling. can be delivered with different connection alternatives. The connection dimensions depend on if the chilled beams are to be installed individually or in series. 3

4 Function has two functions, in part a supply air terminal, and in part a chilled beam. The supply air is fed and distributed inside the supply air beam. The air then passes through the gills on the bottom of the beam and ventilates the room. With its design, scores a very high airchange efficiency value. Tests show that the supply air beam has an air-change efficiency of 64%, which is high compared to other methods of supplying air. When cold-water passes through, both the warm air from the room and the supply air is cooled on the beam's cold surfaces. A considerable mixing of warm room air takes place inside the supply air beam, which means that the temperature of the supply air released from the beam rises. The mixed air then streams through the supply air beam and down into the room. This leads to air circulation in the room, where warm air from the room is continually replaced by cooler air. There are two decisive factors characterising. 1. Low draught risk: Compared to other brands, Lindab's world-patented technology provides direct heat exchange between the cold surfaces of the beam and the warm surfaces of the room via lowtemperature radiation. The radiation quotient for is approx. 30 to 35 % of the total effect. This is a high radiation quotient compared to conventional beams with finned batteries, and this means that the convective share of the cooling effect is lower with. With a given airflow, this results in a higher supply air temperature after the air has passed through the beam. This means that the risk of draughts under the beam is low. 2. Flexible placement: The supply air is fed to the room from the bottom of the beam. This results in a low draught risk. The design also allows the units to be installed at a distance of only 300 mm from each other. Conventional supply air beams normally require a significantly greater separation. This means that offers increased flexibility and freedom of choice with regard to size, number and placement of beams, walls and other fittings in the room. Design The 's design is based on Lindab's world-patented method of metallurgically bonding copper and aluminium. The aluminium plate that constitutes the cooling fin is also metallurgically bonded to the copper pipe that transports the cold water. The shape of the copper pipe allows the easy creation of turbulent currents. This, together with the contact between the copper and the aluminium, boosts to the maximum the energy transport from the cooling surfaces to the cooling water. The metallurgical bond between the copper and the aluminium also eliminates any risk of galvanic corrosion that could possibly be caused by condensation on the surfaces. The supply air can also be fed via a damper, which is supplied as an optional accessory. The water pipes are made of copper. Nevertheless, the water should be oxygen-free to prevent corrosion.

6 Dimensioning Cooling capacity air P a 1. Start by calculating the capacity required for the room, to keep a certain temperature. Lindab s TEKNOsim is an excellent tool for this. 2. Calculate which cooling capacity, or read in diagram 1, that is supplied by the ventilation air 3. Remaining cooling capacity needs to be cooled by the water circuit in. The formula for calculating the capacity air: P a = q ma x c pa x t ra Size comparison by t r = 25 C with: q a = Primary air flow rate P a [W] = q a [l/s] x 1.2 t ra [K] and P a [W] = q a [m³/h] x 0.33 t ra [K] 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] q w = Water flow rate [l/s] q wmin = Minimal water flow rate [l/s] q wnom = Nominal water flow rate [l/s] c pa = Specific heat capacity air [1,004 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. [K] t rw = Temp. diff., room air and mean water temp. [K] t w = Temp. diff. water circuit [K] e tw = Capacity correction for temperature e qw = Capacity correction for water flow P Lt = Specific cooling capacity [W/(m K)] Minimum flow Please note that flows below the recommended minimum water flow q wmin, can result in unwanted air in the water pipes. Exceeding the nominal flows is not recommended as the capacity gains will only be minimal. For minimal (q wmin ) and nominal water flows (q wnom ) please refer to page 9, table 2. P a [W] 600 Cooling Capacity Air P a = q a x 1.2 x t ra t ra [K] Primary Airflow Rate q a [l/s] Diagram 1. Cooling capacity P a as function of the air flow rate q a. If the air supply is 25 l/s and the temperature difference of the supply t ra = 6 K, then the cooling capacity in the chart is 180 W. 6

7 Dimensioning Cooling capacity water P w To calculate 's capacity, follow the steps below. 1. Calculate t rw (room average water) 2. Read off the capacity with the selected airflow and the calculated from one of tables 2 to Calculate the water flow with this capacity P w. 4. Read off the number of parallel circuits in table 1, and calculate the flow per strip. 5. Use diagram 2, to read off the capacity correction e qw at the calculated water flow per strip. 6. Multiply the capacity correction e qw by the capacity q w. 7. Repeat steps 5 and 6. Example 1: What is the cooling capacity of a 4.8 m 53 with Ø water connection and 30 l/s? The room's summer temperature is assumed to be t r = 24.5º C. The cooling water temperature in/out of is 14/17º C. Size Model Ø 1 1 Ø Ø 4 3 Ø 6 Table 1. Number of parallel circuits for, depending on model and connection option. Answer: Temperature difference t rw = t r (t wi + t wo )/2 t rw = (14+17) / 2 = 9 K Read off the capacity for 53 in table Δt rw = 9 K and the supply air velocity is 30 l/s. The value is 877 W. Use the calculated capacity and calculate the water flow: q w = P w / (c pw x t w ) q w = 877 / (4200 x 3) = 0.07 l/s In table 1, read off the number of parallel circuits for 53 with Ø water connection. The value is 3. The water flow per strip will then be 0.07 / 3 = l/s The capacity correction e qw, which is read off from diagram 2, will then be 0.99 and the new capacity: p w = 877 x 0.99 = 868 W. Calculate the new water flow, using the new capacity: q w = 868 / (4200 x 3) = l/s. The water flow per strip will then be / 3 = l/s, and the capacity correction e qw The capacity correction e qw will then be 0.99 and the heating capacity will be 868 W.

21 At Lindab, good thinking is a philosophy that guides us in everything we do. We have made it our mission to create a healthy indoor climate and to simplify the construction of sustainable buildings. We do that by designing innovative products and solutions that are easy to use, as well as offering efficient availability and logistics. We are also working on ways to reduce our impact on our environment and climate. We do that by developing methods to produce our solutions using a minimum of energy and natural resources, and by reducing negative effects on the environment. We use steel in our products. It s one of few materials that can be recycled an infinite number of times without losing any of its properties. That means less carbon emissions in nature and less energy wasted. We simplify construction
