Ventilator assembly
The arrangement (100) has a flow sensor for determining air-volume flow (125) produced by an axial fan (120) and for production of a volume flow-measured value (Vmess). A volume flow-controlling arrangement (160) controls the air volume flow to a predetermined volume flow-reference value (V-s). The...

| Zusammenfassung: | The arrangement (100) has a flow sensor for determining air-volume flow (125) produced by an axial fan (120) and for production of a volume flow-measured value (Vmess). A volume flow-controlling arrangement (160) controls the air volume flow to a predetermined volume flow-reference value (V-s). The volume flow-controlling arrangement is designed to generate a speed-reference value (N-s) for an electrically commutated motor (110) . A speed controller (170) controls the speed of the motor to the speed-reference value. An independent claim is also included for a controlling arrangement for a fan. |
