Functional description
Decentralised supply and extract air units ventilate the room and cover the cooling and heating load in accordance with the technical data. An EC centrifugal fan takes in the outdoor air which then flows through the motorised shut-off damper and the outdoor air filter. Then the outdoor air flows through the crossflow heat recovery unit, which can be bypassed in energetically sensible operating situations and for unit protection. Before the supply air flows into the room as a displacement flow, it is heated or cooled in the heat exchanger if required. 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 indoor air quality is sufficient, the FSL-CONTROL III control system switches to energy-efficient secondary air mode by closing the outdoor air dampers. 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. In case of a power failure, the outdoor air and exhaust air dampers are closed to ensure fire protection, frost protection and to avoid draughts. This is ensured by a capacitor in each actuator.Near the external wall, the supply air is discharged into the room with a medium velocity between 0.5 and 0.8 m/s. Due to the induction effect, the supply air velocity is rapidly reduced after entering the room. As a result, in cooling mode, the supply air spreads out like displacement flow over the entire floor area. Near heat sources such as people or equipment, a lift current is formed by natural convection, so that the air is exchanged primarily in these areas.
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 F7 filter. Once the outdoor air has passed the fan, it flows through the recuperative heat exchanger for heat recovery; it is possible to bypass the heat exchanger in order to pect it, or 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. The extract air first passes a G3 filter (that pects the unit), then flows through the heat exchanger (for heat recovery), the extract air fan and the motorised shut-off damper before it is discharged to the outside as exhaust air. Automatic switching to secondary air mode (only with an air quality sensor) if the room air quality is sufficient. The outdoor air damper closes, the self-powered secondary air damper opens and the extract air fan is switched off. The unit always starts in secondary air mode, which is more energy efficient.
