Functional description
Decentralised supply and extract air units ventilate the room and dissipate the heating load according to the technical data. 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 more energy-efficient. If necessary, the air is heated or (for change-over systems this is an option) by the heat exchanger before it is discharged through the supply air grille; the supply air first flows along the ceiling (Coanda effect) and creates no draughts. The extract air first passes through the outdoor 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 switches over to secondary air operation, which is more energy efficient in any case. The control system compares the setpoint values of the indoor air quality with the CO2 actual values measured with 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 ceiling with a medium velocity. The Coanda effect deflects the air jet upwards, where it remains attached to the underside of the ceiling, thereby increasing the throw distance. Once it has reached the wall, which is located opposite the air outlet, an air curtain is created. The supply air reaching the occupied zone has a very low velocity and rises at heat sources (e.g. people and devices), thus giving rise to natural convection. As a result, the air is primarily exchanged in these areas. The stale air rises to the ceiling from where it is extracted and led outside.
