Installation for venting the interior space of a motor vehicle

An installation for ventilating the interior space of a passenger motor vehicle which includes air inlet and air discharge aperture means terminating in the atmosphere, at least one fresh air channel means leading from the air inlet aperture means into the interior space, fan means and at least one air filter insert means arranged in the fresh air channel means and adapted to be traversed by fresh air for filtering at least one of mechanical and chemical air contaminations, characterized in that at least one air channel means is extended along a space means accessible by way of a large continuous surface means, said one air channel means being enlarged within the area of this space means in a housing-like manner for receiving the air filter insert means and being provided with an opening means for the exchange of the air filter insert means, said opening means being of relatively large surface and adapted to be closed, a heat-exchanger for preheating the fresh air in the fresh air channel means is arranged upstream of the air filter insert means, as viewed in the flow direction, a recirculating line means has a first end terminating in the fresh air channel means, with a second end thereof communicating with the vehicle interior space, interchangeable means for a moisture removal are arranged in the recirculating line means and are traversed by the recirculating air, a variable throttle means at least partly closing the flow cross-section is provided at least in one of the two channel means consisting of the fresh air channel means and of the recirculating line means, a by-pass channel means by-passing the air filter insert means and terminating directly in the atmosphere, terminates in the fresh air channel means downstream of the air filter insert means as viewed in the flow direction, a further throttling means for partly closing the flow cross-section and enabling a shifting of the main flow is arranged within the area of a discharge of the by-pass channel means in the fresh air channel means.
