Note that the product code Swegon SDHW corresponds to the code CWW in the calculation program, followed by the duct size and then the number pipe rows. SDHW125 = CWW 125-3-2,5 SDHW160 = CWW 160-3-2,5 SDHW200 = CWW 200-3-2,5 SDHW250 = CWW 250-2-2,5 SDHW315 = CWW 315-2-2,5
Note that the product code Swegon SDCW corresponds to the code CWK in the calculation program, followed by the duct size and then the number pipe rows. SDCW160 = CWK 160-3-2,5 SDCW200 = CWK 200-3-2,5 SDCW250 = CWK 250-3-2,5 SDCW315 = CWK 315-3-2,5 Select “Cooling” from the calculation program!
Airflow can either be extracted from a seperate roof fan, or via by-pass from the AHU (selected models). In both cases without heat recovery.
*) Additional accessories may be needed
Central = DCV with one sensor
Local = DCV with more than one
Measurements made according to EN 13141-7.
Heating the supply air is energy consumption consumed when supply air is heated to 21 °C degrees.
Warming of infiltrated air is energy consumption consumed when leakage air (outdoor air coming inside from cracks etc.) is heated to 21 °C
The part of the annual energy that the unit recovers up to room temperature 21 °C
The part of the annual energy that the unit recovers up to selected supply air temperature
Heat exchanger efficiency according to SFS-EN308
SFS-EN13141-7 (including fans)
Calculations are done according Finnish national building regulations part D3, D5:2012 and annex 122 by The Ministry of Environment
