System for automatically adjusting the pressure of a fan as a function of the required flow rate, comprising a controlled mechanical ventilation unit (1), from which air from different areas in a single-family home is extracted via ducts (3), said controlled mechanical ventilation unit (1) incorporating: means (5) that as a function of the input pressure in the unit (1) detect the pressure variations in the ducts (3); and a logic control box (7) that stores a reference flow rate/pressure curve, defining above said curve a predetermined band, containing the working zone of the fan (2) that is part of the controlled mechanical ventilation unit (1). |
