Abstract
Regulation device for a motor-driven fan unit of heating and/or air-conditioning apparatus. It comprises means for switching the motor-driven fan unit, and is characterised in that it comprises means for detecting the pressure 4 within a passenger compartment, and a comparator element 3 for comparing the said pressure value obtained with a predetermined value 5 such that, when the pressure detected within the said passenger compartment is higher than the predetermined value 5, the switching means are activated and the motor- driven fan unit 1 operates normally, while, if the pressure value detected is below the predetermined value, the switching means reduce the flow ID through the motor- driven fan unit, as a result of which its velocity is reduced. This avoids the motor-driven fan unit racing when a substantial reduction occurs in the pressure within a passenger compartment.
