Definitions

  • an additional air duct makes it possible to space the outside air inlet even further from the outgoing air outlet and to control a respective position of the outside air inlet and the outgoing air outlet depending on a wind direction.
  • the exhaust air inlet can be connected to the air duct adjacent to one end of the air duct and the supply air outlet can be connected to the further air duct adjacent to an end of the further air duct opposite the end of the air duct.
  • two passages are provided in the outer shell, one for the exhaust air and one for the outside air. In this case, it makes sense to arrange the exhaust air inlet at the end of the air duct and the supply air outlet at the corresponding opposite end of the further air duct and to connect them to the air conditioning system or corresponding bushings in the outer shell.
  • the ventilation device can thus be made particularly compact.
  • the valve and/or the further valve can be controllable by means of the control device depending on the direction of the air flow.
  • the direction of the atmospheric air flow is detected by the sensor.
  • the sensor can be an anemometer, which can also be used to measure a speed of the air flow.
  • a plurality of sensors can also be provided, for example pressure sensors, with the aid of which a differential pressure can be measured at the air duct or at the further air duct. By means of the differential pressure measurement, a negative pressure as well as an overpressure can be measured.
  • a sensor alone can also be used here, since, for example, in the case of a negative pressure, it can be assumed that an overpressure must necessarily be present at another point.
  • the controller can then determine the direction of air flow and the valves correspondingly in such a way that the outdoor air inlet is as far away from the exhaust air outlet as possible and is on the leeward side of the air flow.
  • the valves can also be formed by self-opening flaps.
  • the control device can then be designed as a mechanical control device, for example by one or more damming surfaces that can be actuated with the air flow and whose movement is transmitted to the flaps.
  • the valve and/or the additional valve can be designed with an actuator and a ventilation flap each.
  • the actuator can be an electromagnetic actuator or a servomotor.
  • the valve can be designed in such a way that switching between two valve positions is possible. It is also advantageous if an intermediate position, for example a central position of a ventilation flap, can be set with the valve or the ventilation flap, for example for the theoretical case that there is no wind.
  • the ventilation flap can be designed as a flat, pivotable flap or as a curved, for example semi-circular flap that can be rotated about an axis and completely and/or partially closes the duct sections.
  • a valve 53 is formed on the air duct 47 and a further valve 54 is formed on the further air duct 48, which can be controlled by means of a control device of the ventilation device 42, which is not shown here.
  • the valve 53 and the further valve 54 have half-shell-shaped flaps 55, the position of which can be adjusted or rotated about an axis 56 by means of a drive, not shown in detail here. This makes it possible to divert an air flow in each of the air duct 47 and the further air duct 48 as required.
  • the air duct 47 and the further air duct 48 thus form a guiding device 57 of the ventilation device 42 .
