4 Sound attenuator
5 Fan (supply air and extract air)

11 Extract air filter ISO coarse 50 %
Decentralised supply and extract air units for room ventilation and for dissipating cooling loads and heat loads. An EC centrifugal fan takes in the fresh air, which then flows through the motorised shut-off damper and the fresh air filter.
The fresh air then flows through the rotary heat exchanger, which can be switched off when it is sensible with regard to energy efficiency. If necessary, the air is heated or cooled by the heat exchanger before it is discharged to the room as a displacement flow (this is optional for 4-pipe systems). The extract air first passes through the extract air filter, then flows through the heat recovery unit, the extract air fan and the motorised shut-off damper before it is discharged to the outside as exhaust air. If the room air quality is sufficient, FSL-CONTROL III closes the outdoor air dampers and changes to secondary air operation, which is more energy efficient in any case.
Here, the control system compares the setpoint values of the indoor air quality with the actual values measured at the CO2 sensor and switches automatically between fresh air and secondary air operation. If the power fails, the fresh air and exhaust air dampers are closed to ensure fire protection and frost protection and to avoid draughts. This is ensured by a capacitor in each actuator. The supply air is discharged near the external wall and with a medium velocity between 1.0 and 1.5 m/s.
Due to the induction effect, the supply air velocity is rapidly reduced after the air enters the room. In cooling mode, the supply air displaces the room air over the entire floor area. The convection from people and other heat sources causes the fresh air from the pool to rise and create comfortable conditions in the occupied zone.
