Embodiment Construction

[0027] The drawing shows a motor vehicle ventilation system 1 for a passenger car, the motor vehicle ventilation system 1 is provided with an external air line 3 for supplying external air into the passenger compartment 2, the external air line 3 is provided with a filter 4 and a controllable switching valve 5 , so that it can selectively filter or not filter (bypass operation) suction outside air.

[0028] The motor vehicle ventilation system 1 also comprises a recirculation air line 6 for conveying the interior air from the passenger compartment 2 , and an air intake line 7 leading to the passenger compartment 2 , which has a control valve 8, so that the amount of circulating air is adjusted in proportion to the amount of outside air. A ventilation device 9 , another air filter 11 and a cooling and heating device (air conditioner) 10 are also arranged in the intake line 7 .

[0029] In this case, a further air filter 11 is arranged downstream of the ventilation device 9 and...

Abstract

The present invention relates to an automotive ventilation system which is particularly used for car, which is provided with an outer air pipe (3) for inputting outer air into a carriage (2). The outer air passage is provided with a filter (4) and a controllable switching valve (5) thereby sucking the outer air with filtering or without filtering (bypass operation) selectively. The automotive ventilation system also comprises a circulating air pipe (6) and an inlet air pipe (7). The circulating air pipe is used for conveying the inner air from the carriage (2). Furthermore the inlet air pipe is provided with a control valve (8) so that the amount of circulating air can be adjusted proportionally with the amount of outer air. The inlet air pipe is provided with a ventilation device (9) and a cooling heating device (10). The outer air pipe (3) and the circulating air pipe (6) are communicated with the inlet air pipe (7). The inlet air pipe (7) is provided with the other air filter (11). Thus a particularly effective high-efficiency filter (4) is allowed to be used.

Description

technical field [0001] The invention relates to a motor vehicle ventilation system, in particular for passenger cars, with an external air line for supplying external air into the passenger compartment, the external air line being provided with a filter and a controllable switching valve, To be able to draw in outside air selectively filtered or unfiltered (bypass operation), the motor vehicle ventilation system also includes a recirculating air line and an air intake line for delivering air from the interior of the vehicle compartment air, the air intake line leads into the passenger compartment, and the air intake line has a control valve to make it possible to adjust the amount of circulating air in proportion to the amount of external air, and in the air intake line there are ventilation means and cooling and heating means , wherein both the external air line and the circulating air line lead into the intake line. Background technique [0002] Passengers of motor vehicl...
