Embodiment Construction

[0032] refer to figure 1 , in addition to having a number of other conventional components, the air conditioning system 1 can have at least one blower 2 for driving the air. Furthermore, the air conditioning system 1 comprises a control device 3 by means of which a changeover between circulating air operation and fresh air operation can be effected.

[0033] Refer to attached Figure 2-4 , the control device 3 can be equipped with a control housing 4 with which the control device 3 can form a preassembled unit which can be installed in the remaining air conditioning system 1 in a preassembled state. In any case, the control device 3 comprises a recirculating air inlet 5 (can be seen in image 3 , 4 ), fresh air inlet 6 (can be found in figure 1 , 4 ) and air outlet 7 (can be seen in Figure 2-4 ). The recirculation air inlet 5 is used to introduce recirculation air from the interior of the vehicle (not shown here) which is to be air-conditioned by the air conditioning s...

Abstract

The invention relates to an air-conditioning system (1) for air-conditioning the interior of a vehicle, in particular a passenger car, which has a fan (2) for driving the air and a control device (3) with The circulating air inlet (5) for introducing circulating air inside, the fresh air inlet (6) for introducing fresh air from the environment outside the vehicle, and the inlet for passing the introduced circulating air and / or fresh air to the fan (2) Air outlet (7). The control unit (3) has a control valve (10) which can be adjusted between a circulating air position (UL) and a fresh air position (FL), in which the control valve closes the flow from the fresh air inlet (6) to Fresh air path (11) to air outlet (7) and open recirculation air path (12) from recirculation air inlet (5) to air outlet (7); in fresh air position (FL) control valve closes recirculation air path (12) and open the fresh air path (11). The control valve (10) has at least one one-way check valve (13) which, in the fresh air position (FL), allows a flow of recirculating air (14) from the recirculating air inlet (5) through the control valve (10 ) towards the air outlet (7) and blocking its flow in the opposite direction, thus obtaining improved functionality.

Description

technical field [0001] The invention relates to an air-conditioning system for air-conditioning the interior of a vehicle, in particular a passenger car, which has the features of the preamble of claim 1 . The invention also relates to a control device for the air conditioning system, and a control valve for the air conditioning system or the control device. Furthermore, the invention relates to the use of a control valve or a control device in said air conditioning system. Background technique [0002] A vehicle's air conditioning system typically includes a fan to move the air. The air used for air conditioning can be introduced into the fan from the environment outside the vehicle, this is the so-called fresh air. Likewise, air for air conditioning can also be brought in from the interior of the vehicle, this is called recirculated air. In order to be able to switch between the introduction of fresh air and the introduction of recirculated air, the air conditioning sys...
