Functional description
Decentralised supply and extract air units for room ventilation and for dissipating cooling loads and heat loads. An EC centrifugal fan takes in the outdoor air which then flows through the motorised shut-off damper and the outdoor air filter. The outdoor air then flows through the cross flow heat recovery unit, which can be switched off if it is more energy efficient.
If necessary, the air is heated or cooled by the heat exchanger before it is discharged to the room as a displacement flow. The extract air first passes 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 indoor 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. The control system compares the room air quality setpoint value to the actual value measured by the CO2sensor and switches automatically between outdoor air and secondary air operation.
If the power fails, the outdoor 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. As a result, 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 outdoor air to rise and create comfortable conditions in the occupied zone.
