Use Lindab is specially designed as a combined HTC and LTH beam High Temperature Cooling and Low Temperature Heating. Due to the customized coil, the beam delivers an outstanding cooling and heating effect per degree temperature difference between the water circuit and the room temperature. This means that you get great capacities, at a relatively high running temperature. All in all, the beam can save a lot of the energy cost on cooling and heating. Installation I-0 is installed into a false ceiling, and can be suspended by hangers or threaded rods. Worth noting Cost saving high output beam that delivers an excellent capacity for both cooling and heating, while running the same temperature set for both functions. Pressure authority in the beam means that regulation of the air pressure is a fast and easy task. Lindabs active chilled beams are Eurovent-certified and tested according to EN-.

Great effect through induction 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 room air to be induced into the ventilation air through the coil. The volume of the room air is two to seven times that of the ventilation air. The air is cooled or heated as it passes through the coil, which consists of aluminium fins with copper pipes filled with running water. While passing through the coil, the induced room air will either be cooled or heated, according to the need in the room. High temperature cooling The Lindab beam presents a whole new perspective on cooling, heating and ventilation. Minimizing the figures on the energy account, by reclaiming the cooling and heating energy in the AHU air temperature recovery unit is a natural part of any ventilation system of today. Why not do the same on the water circuit? Compared by weight, water can carry approximately 00 times as much heat energy as air. In most buildings, the need for cooling and the need for heating are two independent factors that do not have a direct relation to each other. There may be a need for cooling on the south façade and a need for heating on the north façade at the same time. Air duct Copper pipes Cooled air Warm indoor air Picture. is based on the induction principle. Normally this scenario will be handled by running a cooling and a heating unit at the same time, to cool the rooms facing south and heating the rooms facing north. But why not use the in-house energy, by distributing the excess heat energy from the south façade to the north façade? Previously no system has been able to deliver this functionality, but with Lindab it is now possible. By running an inlet temperature of 0- C, and an outlet temperature of - C for both heating and cooling, the energy needed to sustain the running temperature will in many cases be provided by the building itself. The specific temperature set will be dependant on the season. The temperatures should be defined for Winter, Summer and Autumn+Spring. Water coming back from the warm southern façade, will be mixed with the colder water from the north façade, thereby creating the desired output temperature once more. In some cases it may be necessary to run either a cooling or heating unit to achieve an optimal output temperature, but it will never be necessary to run both at the same time with the Lindab system ever again. The result: Gain a great indoor climate, while saving both money and the environment. Lindab can be combined with any conventional heating or cooling source, including air-to-water and water-to-water heat pumps. Coanda effect
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 side 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 Fixed and flexible The general idea of a HTC system, is to run a fixed airflow at a fixed pressure. At the same time, the high capacity found in the water circuit and the beam coil will autoregulate the temperature, both for heating and cooling. 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 is accessible from below.

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 flows Please note that flows below the recommended minimum flow, can result in unwanted air in the water pipes.

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.

Example Cooling: Summer What is the cooling capacity of a.0 m with l/s and pressure of 0 Pa? The room summer temperature is assumed to be t r. C The cooling water temperature in/out of is 0/ C. Answer: Temperature difference t rw = t r (t wi + t wo )/ t rw = C - (0 C + C) / =. K Active length: L act =.0 m - 0. m =. m q a / L act = l/s /. m = l/s/m 0 Read off, from diagram : P Lt = W/(m K).

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.

Water capacity: P w = W/(m K) K. m = 0 W Use the calculated water capacity and calculate the water flow: q w = P w / (c pw x t w ) q w = 0 / (00 x ) = 0.0 l/s The capacity correction e qw will then be 0. (see diagram ) and the new capacity: P w = 0 x 0. = 0 W. Using the new heating capacity, a new water flow is calculated. q w = 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. 0,0 0.0 0, 0. 0,0 0.0 0, 0. 0,0 0.0 0, 0. 0 0,0 0.0 0.0 0,0 0,0 0.0 0, 0. 0, 0. 0. 0, Diagram.
