4 0 Function is a facade system with a heating, cooling and ventilation functions. For installation there are supplementary parts for heating, cooling and ventilation (see under System Accessories). uses the supply air's driving power, which through induction creates a flow of air through the battery, thereby ejecting cooled or heated air from the system (see picture ). On the water side, the individual room temperature is controlled by an electronic control system, Regula Combi, with the heating and cooling in sequence. The control feature ensures that the heating and cooling are not activated at the same time. provides high cooling effects at operating pressures of 00 to 0 Pa. has been tested according to the V method at the Technical Research Institute of Sweden. Additional functions include a condensation guard, Regula Secura, which prevents condensation formation, and a service hatch that provides the maximum accessibility to the battery for cleaning and inspection. Design 's technical design provides the maximum output. The heating and cooling battery is installed to ensure counter-flow heat exchange between the incoming room air and the cooling water in the battery. Induction nozzles Cooling and heating battery Cooled/heated air Room air This technical solution provides high cooling effects, while allowing the supply cooling water temperature to be kept low, without condensation problems. 's end plates, sides and air duct are made from galvanized sheet steel. A service hatch is located on the front edge of the system. All of the heating and cooling battery is accessible for cleaning from both sides through this service hatch. When open, it also provides access to all the ventilation duct's intake nozzles. The battery has separate circuits for cooling and heating water. The circuits are made from copper pipe that has been expanded mechanically to ensure contact with the aluminium ribs. The battery is mounted horizontally and is easily accessible for cleaning. The water circuits are pressure-tested along their entire length to. MPa for pressure class NT 0. The cooling feed pipe is insulated against condensation. To protect the system further against condensation, a condensation guard can be installed. The condensation guard provides significantly increased security against condensation. The Regula Secura condensation guard is positioned next to the battery to detect the formation of moisture. If condensation does form, the cooling water circuit valve closes to prevent it. Then, it re-opens to detect what output can be achieved without condensation forming. The water pipes are made of copper. Nevertheless, the water should be oxygen-free to prevent corrosion.

5 Hygiene is designed for easy cleaning and service. The service hatch provides unrestricted access to the system's battery both from above and below. On delivery, the system's battery is shielded with protective wrapping and the outlet with protective tape. This prevents dust and dirt from getting into the system before it is put into operation. Picture. Cleaning is easy with the service hatch on the front. Picture. installed without columns. Initial settings The facade system is supplied with the ordered airflow at a given air pressure. On-site adjustment is therefore not required. The Kv value of the control valves is preset at the factory (standard). If necessary, the airflow and pressure drop on the water side can also be adjusted on site. Picture. installed with columns. 0

9 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. 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 [W] P a [W] Luftens Cooling kyleffekt capacity air P a P = = q a qx p x., x x t ra t t ra [K] Primary air flow Luftflöde 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.

10 0 Dimensioning Cooling capacity water P w Follow the instructions below to read off the effect from the diagram.. Calculate t rw (room average water). Product length L minus 0. m, to obtain the active length L act.. Divide the airflow 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. P Lt Lt [W/(m K)] Specific Cooling Capacity Example Cooling: What is the cooling capacity of 000 with l/s and pressure of 0 Pa? The room's summer temperature is assumed to be.ºc. The cooling water temperature in/out of is /ºC. Answer: Temperature difference: t rw = t r (t wi + t wo )/ t rw =. - (+) / = K Active length: L act =.0 m - 0. m = 0. m q a / L act = l/s / 0. m =. l/(s m) Read off, from diagram : P Lt = 0.

12 heating effect sound Effect according to the V method The tabulated data for the cooling effect is measured according to the V method at the Technical Research Institute of Sweden. The test measurements are made on the 00 system at 00 Pa, 0 Pa and 0 Pa, with casing and grill mounted on the system. Operating pressure at 00 Pa (0- l/s) The V method means that the room temperature is measured at. m above floor, i.e. the temperature in the occupied area. The V method gives a lower effect value compared to conventional measurements. This is because conventional measurement methods use the temperature of inlet air to the facade system to calculate the effect values. Inlet air has a lower temperature than that in the occupied area. 0 * Room height should be less than. m. 0* 00 < 0* < 00 < * < * 00 < 00 0 < 00 0 < * < < < * < Table -. Table -.
