Use Lindab's natural convection beam is the lightest chilled beam available on the market. Podium is 's sister product; the difference between the two beams is that Podium also uses supply air. is mounted on the ceiling and supplies cooling through natural convection and radiation, which results in a draught-free climate. 5% of the cooling supplied by comes from radiation while 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. The product offers many possibilities and great flexibility. can be coated in any colour. Installation Worth noting is the lightest chilled beam on the market, a beam 6.0 m long with a width of 5 cm that weighs only 8.8 kg. has flat and easily accessible surfaces, which contributes to good indoor hygiene. Furthermore, the 's height is only 0 mm, which provides to great freedom of placement. Lindabs passive chilled beams are tested according to EN-58. Key figures Length: Width: Height: Capacity: 00-6000 mm (steps of 00 mm) 70, 50, 50, 600 mm 0 mm 90 W Calculation setup Room temp: 5 C, Water temp: -7 C is installed either suspended or recessed into a ceiling. can be delivered with different connection options. The connection dimensions depend on whether the chilled beams are to be mounted individually or in series. 06-0-0
Function As cold water passes through the chilled beam, the warm air from the room is cooled against the cold surface of the beam. The cooled air, which is heavier, then streams through the chilled beam and down into the room. This causes air to circulate in the room, as warm air from the room is continually replaced by colder air. However, this is where the similarities with other chilled beams cease. There are two decisive factors that are distinguished by their functionality:. Compared with other brands, Lindab's worldpatented technology provides direct heat exchange between the cold surfaces of the chilled beam and the warm surfaces of the room via long-wave radiation. The radiation quotient for is roughly 0 to 5 % of the total effect. This is a high radiation quotient, compared to conventional beams with finned batteries, and it results in a lower flow of chilled air beneath the beam. This, in turn, reduces the risk of draughts under the beam.. Compared to a conventional beam, provides a significantly higher cooling effect at lower room temperatures. The reason for this is that the convective heat transfer in the gills of the chilled beam does not decrease at the same rate, as the heat transfer in the vertical ribs in a conventional beam, when the room temperature falls during the day. As a result, can provide a higher cooling effect during the day, and thereby store more "cooling energy" in the building structure. If and a conventional beam yield the same output at a temperature difference of 0 C between the mean coolant temperature and the air in the room, provides a 0 % higher cooling effect than the conventional beam, when the temperature difference has dropped to 5 C. The direct heat exchange, via the high radiation quotient, with the surfaces of the room and the relatively high cooling effect, even at lower room temperatures, allows a large amount of "cooling energy" to be stored in the building structure during the day. As a result, provides a lower room temperature than would be provided by a conventional cooling beam. Design The 's design is based on Lindab's world-patented method of metallurgically bonding copper and aluminium. The aluminium plate that makes up the cooling fin is also metallurgically bonded to the copper duct 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 for galvanic corrosion that could possibly be caused by condensation on the surfaces. provides a high cooling effect per surface unit, which leads to resource-efficiency and a low weight for the product. is made of 00% recyclable materials. The water pipes are made of copper. Nevertheless, the water should be oxygen-free to prevent corrosion. Picture. 7, 5 and 5. 06-0-0

Dimensioning Cooling capacity P w To calculate s cooling capacity P w, follow the steps below.. Calculate Δt rw.. Read off the cooling capacity P w per metre and K in table.. Calculate the water flow q w.. Read off the number of parallel circuits in table. 5. Calculate the water flow q w per strip. 6. Read off the capacity correction e qw in diagram. 7. Multiply the capacity by the capacity correction. 8. Repeat steps 5 to 7. Size Model 7 5 5 Ø0 Ø Ø Ø 6 Table. Number of parallel circuits for, depending on model and connection option. Example : What is the cooling capacity of a. m -5 with Ø water connection? The room's summer temperature is assumed to be.5 C. The cooling water temperature in/out of is /7 C. Answer: Temperature difference: t rw = t r (t wi + t wo )/ t rw =.5 C - ( C + 7 C) / = 9 K In table, read off the cooling capacity P w for -5. m and t = 9K. The value is 768 W. Use this capacity to calculate the water flow in with the following formula: q w = P w / (c pw x Δt w ). q w = 768 W / (00 Ws/(kg K) K) = 0.06 l/s In table, read off the number of parallel circuits for -5 with Ø water connection. The value is. The water flow per strip will then be: q w = 0.06 l/s / = 0.0 l/s The capacity correction e qw, which is then read off from diagram, will be 0.95 and the new capacity: P w = 768 W x 0.95 = 70 W. Calculate the new water flow using the new capacity: q w = 70 W / (00 Ws/(kg K) K) = 0.058 l/s. The water flow per strip will then be q w = 0,058 l/s / = 0,09 l/s, and the capacity correction e qw approx. 0.95. The capacity correction e qw will then be 0.95 and the cooling capacity is calculated to be 70 W.

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.
