| 摘要 |
The invention concerns a centrifugal ventilation device (1) comprising at least one delivery outlet (20) and at least two fluid intakes (2, 3) arranged on either side of a ventilating wheel (4) capable of being driven in rotation by drive means, each intake (2, 3) being associated with a control system (30) of the fluid flow suction for producing an asymmetric suction flow rate between the two intakes (2, 3) characterised in that the intakes (2, 3) are provided with control systems mutually different by their mechanical structures and the relative fineness of their control. The invention is destined for industrial use. |
