3 0 Picture. Architect Circum, Luna and Prisma. Introduction Architect is a flexible and aesthetical, free hanging active chilled beam, designed to deliver a great flexibility and a perfect indoor climate. Equipped with the Lindab JetCone technology, along with adjustable air deflectors, the Architect beam offers the possibility of on-site adjustment, thereby allowing the beam to adapt to future changes in ventilation need. Worth noting Lindabs active chilled beams are Eurovent-certified and tested according to EN-.

4 0 Highly flexible active chilled beam The Architect delivers great cooling and ventilation in an architectural, free hanging wrapping. Equipped with the market leading Lindab JetCone technology, the Architect delivers a precision in air volume handling, only known to Lindab products. Combined with the unique Architect air deflectors, the Architect delivers a very high level of flexibility, as well as the possibility of adapting the beam to future demands, in a fast and easy fashion. Many mounting possibilities With the mounting options, Ceiling, Wall, or Free hanging, the Architect will fit any mounting need. Designed for visible mounting, the Architect can be fitted on any plane surface, or even freely suspended, with a perfect result. To hide the air duct and water pipes, the Lindab Architect can be delivered with a Connection Cover (Available in any length up to 00 mm), in order to perfect the overall design in the room. Air duct Copper pipes Freedom of design With three different designs, the Architect Luna, Prisma and Circum can fit any layout design. Project specific adaption based on the actual design of the building is also possible when using the Lindab Architect Luna, Prisma and Circum beam (special). As the beam consists of an independent body and an interchangeable faceplate, the initial installation of the beam can be carried out, before the design of the faceplate is decided. Detachable faceplate Adjustable Air deflectors Battery Picture. Architect Luna, Prisma and Circum is based on the induction principle.

5 JetCones 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. Architect Luna, Prisma and Circum are fitted with the JetCone air volume adjustment technology. The JetCone technology provides a market leading flexibility, with the possibility of adjusting the air diffusion pattern and air volume according to air pressure. Adjustment is made by changing the positions of the four adjustment pins. The adjustment pins can be set in any of the 0 steps, thereby offering a total of 0 different settings. The adjustment is done without any tools, making adjustments a fast and easy process. The fast adjustment system offers a unique opportunity within planning, as the air flow can be adjusted at any point after ordering. Air deflectors In addition to changing the air flow and air diffusion pattern, the Architect Luna, Prisma and Circum also offer the possibility of adjusting the air spread pattern. Using the individually adjustable air deflectors, the air spread pattern can be adjusted to optimize an almost endless list of scenarios, and thereby secure the best possible indoor climate in any situation. Adjustments are simply made by changing the position of the air deflectors, according to the desired degree of air spread. 0 0 Pos. Pos. Adjustment pins Pos. Pos.

7 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 cooling capacity needs to be cooled by the water circuit in Architect. 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] 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. [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)] 0 P a [W] Cooling Luftens capacity kyleffekt air 00 P a = q a, t ra t w [K] Primary air Luftflöde flow rate q a [l/s] Diagram. 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 air of the air is 0 W.

8 0 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 airflow 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.. Multiply the specific cooling capacity that was read off by t rw and active length L act. Example Cooling: What is the cooling capacity of a. m Architect 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 Architect 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 = 0 l/(s m) Read off, from diagram : P Lt =. W/(m K). Cooling capacity: P w =. W/(m K) K m = W NB! The capacity diagram applies for the nominal water flow of nom = 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 capacity, which is read off, by this factor as shown in example for heating.

9 Dimensioning Capacity correction for water flow e qw Example Heating: What is the heating capacity of a. m Architect 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 Architect 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 = 0 l/(s m) Read off, from diagram : P Lt =. W/(m K). Water capacity: P w =. 0 K m = W Use the calculated water capacity and calculate the water flow: = P w / (c pw x t w ) = / (00 x ) = 0.0 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: = / (00 x ) = 0.0 l/s Read off the capacity correction e qw at 0. and calculate the capacity: P w = x 0. = 0 W Using the new heating capacity, a new water flow is calculated: = 0 / (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 0 W. 0 Capacity correction e qw Cooling Heating Diagram.
