Problems solved by technology

[0005] However, the aforementioned systems have the disadvantage that they can be a source of noise in the intake area at higher speeds and require a narrow ventilation cross-section
Furthermore, this solution requires additional mechanical elements that need to be controlled, which on the one hand can be a cause of failure and also increase manufacturing costs

Embodiment Construction

[0045] figure 1 A motor vehicle 2 is shown with a ventilation system 4 according to the invention.

[0046] The ventilation system 4 has a fresh air supply 6 through which fresh air 8 reaches the ventilation system 4 . The adjustable fan 10 serves to generate a predetermined volume flow of fresh air in the vehicle interior 12 in which passengers are located. The fresh air 8 is heated or cooled as required by means of the heat exchanger 14 , or both (eg for drying the fresh air 8 ) are heated and cooled simultaneously. The heated or cooled fresh air 8 is then introduced into the interior 12 .

[0047] The heat exchanger 14 has an air conditioner evaporator and a heat exchanger for discharging engine heat to fresh air 8 .

[0048] The control and / or regulating device 16 serves to control the fan 10 and the heat exchanger 14 . For this purpose, the control and / or regulating device 16 receives a preset temperature via a temperature selector switch 18 which is usually arranged ...

Abstract

The invention relates to a ventilation system for a passenger compartment (12) of a motor vehicle (2) comprising a fresh air inlet (6), a heat exchanger (14) for heating and / or cooling the supplied fresh air (8), a fan (10) having adjustable power for creating a fresh air flow into the passenger compartment (12), a speed sensor (20) for determining a current vehicle speed (v) and / or a pressure sensor, a temperature specification device (18) and a control and / or regulation device (16) for controlling and / or regulating the heat exchanger (14) and the fan (10), wherein the control and / or regulation device (16) is designed to lower the power of the fan (10) and to increase and / or lower the heat volume given off or taken up by the heat exchanger to the fresh air (8) with rising vehicle speed (v) and / or rising dynamic pressure.

Description

technical field [0001] The invention relates to a ventilation system for the passenger compartment of a motor vehicle, comprising a plurality of interacting components with a fresh air supply, a heat exchanger, a fan and a controllable or adjustable An integral part of a control or regulation device. Background technique [0002] Ventilation systems of the type mentioned at the outset are known in the prior art. It is known in the prior art that at high vehicle speeds, for example above 130 km / h, a dynamic pressure head is generated in the area of ​​the fresh air supply device for supplying the passenger cabin with fresh air, which leads to more air into the ventilation system. This results in a greater air volume flow into the vehicle interior. In warm operation, the vehicle therefore heats up additionally at higher speeds because more air flows through the heat exchanger of the ventilation system. In cold operation, ie when the air conditioner is switched on, more cold...
