An arrangement for automatically controlling the air conditioning of a vehicle, comprising a vehicle interior fan (4, 5) and a recirculation valve (7) arranged adjacent a fresh air intake (2). The valve can be steered between two valve settings. When the valve is adjusted to a first setting, external air is taken into the vehicle. When the valve is adjusted to the second of its two settings, the air in the vehicle interior is recirculated. An impurity sensor (9) is connected to an input of a control device (13), which is constructed to compare the output signal of the air impurity sensor (9) with a calculated or detected instantaneous value of air impurities within the vehicle interior and to adjust the recirculating valve (7) to its recirculating mode when the outer signal of the air impurity sensor (9) indicates a value which is higher than the air impurity value in the vehicle interior. |
