2 ADVANTAGES OF is an enclosed climate beam with integrated circulation air openings in the lower section. This means the suspended ceiling can be built without taking the circulation air openings into consideration. Accordingly, the circulation air openings never come into contact with the suspended ceiling area. Two-part lower section that permits easy inspection of the coil, without opening or removing the lower section. can be supplemented with radiant heat in the lower section, waterborne or electric. Air can be connected at six different places. This allows the quantity and location of the connections to be changed right up until the time of installation. can be supplemented with Swegon comfort guarantee ADC. Function Figure 1.

5 TECHNICAL SPECIFICATION Cooling The capacity is measured in accordance with the V-publication 1996:1 and Nordtest NT VVS 078 (the Norwegian Building Research Institute). On with ADC an output factor of 0.95 is used to calculate the capacity from tables 1-6 (waterborne cooling) and diagram 4 (waterborne heating). Selection tables 1-6 The tables are listed according to the duct pressure and nozzle configuration, i.e. the number of nozzles active to supply air to the room. By utilising alternative nozzle configurations (Tables 1-6) the air flow rate, duct pressure and cooling capacity can be influenced. The following can be read from the selection guide: - Climate beam s length (m) - Primary air flow (l/s) - Sound level with open damper (db(a)) - Nozzle pressure (Pa) - Air cooling capacity P l (W) - Water cooling capacity P k (W) - Pressure constant Important! The total cooling power is the sum of the air-based and the water-based cooling capacities. Units of measure P: Output W, kw t r : Room temperature C t m : Mean water temperature C v: Velocity m/s q: Flow l/s p: Pressure Pa, kpa Δp: Pressure drop Pa, kpa ΔT m : Temperature difference [ t r - t m ] C ΔT: Temperature difference between supply-return C Supplemental index: v = heating, k = cooling, l = air. i = adjustment The pressure drop on the water side is calculated according to the formula: Δp k = (q k / k pk ) 2 [kpa] where: Δp k = the pressure drop in the water cirkuit (kpa) q k = the water flow (l/s), taken from Diagram 1 k pk = Pressure constant, taken from Tables 1-6 The air s cooling effect calculated according to the formula: P l (W) = q l x 1.2 x ΔT l, where: P l = The air s cooling effect (W) q l = Air flow (l/s) ΔT l = temperature difference ( C) Nozzle configuration By plugging the nozzle holes in the air duct, based on nozzle configuration 1, you can redo the nozzle configuration as follows: For configuration 2: plug every fourth hole (Both sides) For configuration 3: (small air flow rate) plug every other hole (Both sides) For configuration E: (small air flow rate) plug two of three holes on the low flow side.

12 Heating Additional heat - coil. The convective coil heating function is only intended as an addition in those cases where room gains exceed losses, but then under short periods when there is a need of small additional heat, i.e. during the evenings and at night. function of heating flow q v (l/s). Diagram 4. Heating effect - four pipe system Pv (W) A requirement for the additional heat to be of use is that the supply air fan is running. The mixture of hot and cold air takes place with the help of the supply air, which is why the temperature distribution in the room is fully dependent on the condition between the supply air and the heating capacity of the unit. Heat is supplied along the ceiling which, in order to work, requires a low supply temperature and a specific layouts. Normally a temperature gradient of 3 C between the floor and ceiling is obtained. Recommendations for the additional heat function Max. permissible flow temperature, heating: 60 C Lowest warm water flow: l/s Disc pressure, p i : >30 Pa It is recommended for facades with large glazed areas that radiation from colder surfaces is compensated for using radiant heat in the ceiling unit or radiators along the facade.

Capacity increase with blowing. When the ventilation air is available, the capacity increases on the radiant heat lower section. The size of the capacity increase is dependent on the amount of ventilation air. In table 9 the capacity correction factor is presented as a function of the ventilation air flow. With blowing with ventilation air the capacity of the radiant lower section increases, table 8, according to the following: P corrected = P v (table 8) x k corr (table 9).

15 Example Cooling An office with the dimensions w x d x h = 4.5 x 3 x 2.7 m has a cooling requirement of 60 W/m 2, total 810 W. The air flow should not exceed 24 l/s. The sound level from installations must not exceed 30 db(a). Selected room temperature summer: 25 C Cooling water temperature 15/17 gives ΔT k = 2 C. Supply air temperature 16 C gives: ΔT l = 9 C The climate beam should be placed parallel with the perimeter wall and equipped with radiant heat to compensate for the cold draught and asymmetry radiation from the window. Example Heating An office with the dimensions w x d x h = 4.5 x 3 x 2.7 m has a heating requirement of 200 W. The air flow should not exceed 24 l/s. The sound level from installations must not exceed 30 db(a). Selected room temperature winter: 22 C The heating water s supply temperature is 40 C and the available water flow rate is l/s The climate beam should be placed parallel with the perimeter wall and equipped with radiant heat to compensate for the cold draught and asymmetry radiation from the window. SOLUTION Cooling As the unit should be placed parallel with the perimeter wall we select the nozzle configuration E. 25% of the air flow should be directed towards the perimeter wall and 75% of the air flow in towards the room. The supply air that maintains a temperature of 16 C gives the cooling effect P l = 1.2 x 24 x 9 = 259 W. The remaining cooling requirement = 550W should be cooled using water. With the cooling effect requirement 550 W and a temperature increase on the water: ΔT k = 2 C we note from Diagram 1 the required water flow l/s. Diagram 3 show that the water flow per unit l/s does not cause a drop in capacity due to the insufficient turbulent flow in the coil. Table 5 gives for length 2.4 m and the air flow 24 l/s the cooling effect 606 W at ΔT mk = 9.0 C, which is adequate for the room load. The pressure drop is calculated based on the water flow rate of l/s and the pressure constant kpk = 0.02, which is taken from Table 5. The pressure drop will then be: Δp k = (q k / k pk ) 2 = (0.066 / 0.02) 2 = 10.9 kpa. The pressure drop can also be taken from Diagram 2. SOLUTION Heating From Diagram 5 we note, with the available water flow l/s and effect output 200 W, a temperature drop on the water: ΔT v = 3.7 C. From Table 8 we note at ΔT mv 16 C the heating effect 53 W/ m. From Table 9 we see the capacity increase due to blowing with the air flow 10 l/s m is 77%. Remembering the active length of the unit L Akt = L Nom m = = 2.28 m the heating capacity of the unit P v = 53 x 1.77 x 2.28 = 214 W, which is sufficient to cover the heating requirement. From Diagram 6 we note the pressure drop which for the water flow rate l/s and length 2.4 m becomes 1 kpa. Solution: 1 x 2.4 m with radiant heat in the lower section placed parallel the with window facade. Sound level In Table 5 we see that the sound level is below 20 db(a) when the damper is open. In Diagram 7 we see the throttling range for the damper CRPc is approximately: 50 Pa. Solution: 1 x 2.4 m placed parallel with the perimeter wall. Pressure drop, sound level, any corrections for insufficient turbulent flow and functional lengths can be quickly and easily accessed using the Swegon BeamSelect software. 15
