VENTILATED CABIN PROVIDING A CONSTANT AIR FLOW

Ventilated enclosure (10) comprising an interior ventilated space (12) and a ventilation device (14), in which the ventilated enclosure (10) comprises at least one closed-loop air circuit (24) defined through the ventilation device (14) and the interior ventilated space (12) and in which the ventilation device (14) comprises a fan (23) for moving air in the closed-loop air circuit (24) and a control unit (30) for controlling the speed of the fan (23), the control unit (30) being configured to vary the speed of the fan (23) to ensure a constant setpoint flow rate. The ventilation device (14) comprises a sensor (34) for measuring a pressure difference between two points of the closed-loop air circuit (24), the control unit (30) being configured to set the speed of the fan (23) based on the measurement of pressure difference.
