Description

The invention relates to an air conditioning device for air conditioning a passenger compartment of a vehicle and to a vehicle.

Air conditioning devices in vehicles have the purpose of conditioning the air in a passenger compartment of the vehicle, in particular of heating or cooling and cleaning it.

For this purpose, conventional air conditioning devices have an air conditioning device which is often arranged in a cockpit area of the vehicle. The conditioned air can be released into the passenger compartment via air outlets in the cockpit area. The air outlets can be adjusted manually or automatically to enable direct air flow to seated passengers.

Conventional air conditioning devices, in particular conventional air conditioning units, are, however, relatively large and bulky and accordingly take up a lot of space in the vehicle. The installation space is getting smaller and smaller due to the integration of more and more electronics, in particular comfort and multimedia systems, especially in the area of the cockpit, so that an integration of the air conditioner in the area of the cockpit becomes more and more difficult.

The seating position also becomes more variable with increasing (partial) automation of vehicles, so that an air flow must be possible for seated and reclining passengers. Conventional air-conditioning devices in which the air flow occurs through air outlets in the cockpit area cannot provide sufficient air flow to lying passengers.

The object of the invention is to create a compact and space-saving air conditioning device while avoiding the disadvantages of the prior art.

According to the invention, this object is achieved by an air conditioning device for air conditioning a passenger compartment of a vehicle, which has an air conditioning device that includes a longitudinal axis and at least one fan, at least one heat exchanger and at least one air outlet duct with several air outlets, the fan, the heat exchanger, the at least one Air outlet duct and the air outlets are arranged along the longitudinal axis. Due to the elongated design and extension of the air conditioner, the air conditioner can be made compact, especially in the lateral direction, so that the air conditioner has completely different dimensions than conventional air conditioners. In this way, the air conditioner can be installed in other areas of the vehicle, for example in the roof area, which were previously out of the question.

The longitudinal axis can represent a central axis of the vehicle. Uniform air conditioning of the vehicle interior can thus be achieved by the air conditioning device or the air conditioning unit.

For example, “along the longitudinal axis” is understood to mean that the corresponding components extend largely in parallel, possibly taking into account a curvature of the longitudinal axis.

Optionally, the longitudinal axis can have a curvature. As a result, the air conditioning device, in particular the air conditioning device, can be adapted to certain shapes and structures of vehicle components, for example an inside of a vehicle roof.

In particular, the individual components of the air conditioner are also arranged one above the other, based on the longitudinal axis. In other words, the individual components of the air conditioner, in addition to the longitudinal arrangement, are also arranged essentially vertically. In this way, the air conditioner can be designed to be narrow in the lateral direction with respect to the longitudinal axis.

The individual components of the air-conditioning device are preferably not arranged laterally next to one another in relation to the longitudinal axis. For example, the components extend predominantly parallel to the longitudinal axis. In this way, the air conditioner can be designed to be narrow in the lateral direction with respect to the longitudinal axis.

One embodiment provides that the at least one fan is fluidically connected to the plurality of air outlets of the at least one air outlet channel, the at least one heat exchanger being arranged between the fan and the plurality of air outlets. The fan serves as an air supply through which the heat exchanger is supplied with air and which heats or cools it. The heat exchanger therefore has the function of air heating or air cooling. The heated or cooled air can flow out of the air outlets in a targeted manner into certain areas of the passenger compartment or diffusely into the passenger compartment of the vehicle. This enables air conditioning of the passenger compartment.

In particular, the fan, the heat exchanger and the air outlet duct form a unit which is each assigned to a row of seats in the vehicle. This allows heated or cooled air be specifically let out in the rows of seats in the vehicle.

In another embodiment, two air outlet ducts are provided, one fan being directly fluidly connected to both of them, or two fans being provided which are each directly fluidically connected to an air outlet duct. The component and manufacturing costs can be reduced by an arrangement with only one fan. In an arrangement with two fans, smaller fans can be used and a reliable air supply to the heat exchangers and air outlets can be ensured over longer distances.

In particular, the air outlet ducts and the fans are provided one behind the other on the longitudinal axis. In this way, the narrow overall shape of the air conditioner can be guaranteed.

For example, the fans are radial fans. A radial fan can have outlets offset by 180 °, with both outlets lying on the longitudinal axis and each connected to an air outlet duct.

According to one aspect, the air conditioning device has an air supply duct which extends along the longitudinal axis and which is fluidically connected to one of the at least one fan, in particular wherein the air supply duct extends between two of the fans. The intake of the required air can be spatially separated from the air conditioning unit through the air supply duct, thus reducing the noise emissions in the area of the air conditioning unit.

It can be provided that the air outlet channel of a fan assigned to the air outlet channel is at the same time the air supply channel of another fan assigned to the air supply channel. In this way, an additional air supply duct can be saved and the number of components can accordingly be reduced.

In particular, the air supply duct is arranged above or below one of the at least one air outlet duct. Accordingly, the air supply duct is not arranged laterally next to the other components of the air-conditioning device, as a result of which the width of the air-conditioning device can be reduced in the lateral direction with respect to the longitudinal axis.

The air outlets are preferably designed to be elongated, the air outlets extending along the longitudinal axis. In this way, the height of the air outlets and therefore of the air conditioning device, based on the longitudinal axis, can be kept low while ensuring a volume flow of air that is necessary for air conditioning the passenger compartment. In this way, the area in the passenger compartment exposed to the flow can also be widened and a pleasant draft can be ensured.

Here, an elongated extension means a longitudinal extension that is greater than a transverse extension of the air outlet, in particular by at least the factor 5 .

Another aspect provides that an outflow direction of the air from the air outlets can be set manually and / or automatically. This enables an optimal air flow in certain areas in the passenger compartment.

The air conditioning device or the air conditioning device can optionally be coupled to a position detection system. As a result, a position of a passenger in the passenger compartment can be detected and the outflow direction of the air from the air outlets can be automatically controlled on the basis of the position information.

In one embodiment, the air conditioning unit has a condensate line that extends along the longitudinal axis and is connected to at least one heat exchanger for receiving condensate, in particular wherein the condensate line is arranged laterally offset with respect to the longitudinal axis to the at least one heat exchanger or below the at least one Heat exchanger runs. In this way, the condensate formed in the heat exchanger can be discharged from the air-conditioning unit in a controlled manner, whereby an uncontrolled collection of liquid in the air-conditioning unit can be prevented.

An offset is preferably provided between a condensate drain of a heat exchanger and the condensate line. The offset can prevent the condensate from flowing back into another heat exchanger, which is also fluidically connected to the condensate line.

A further embodiment provides that the air conditioning device has an air supply device which has at least one supply fan and at least one air supply duct, the at least one supply fan being arranged below the longitudinal axis of the air conditioning device and the at least one air supply duct the at least one supply fan with the air conditioning device, in particular the Air supply duct fluidly connects. In this way, the air required for air conditioning the passenger compartment can be conveyed to the air-conditioning unit from an area that is spatially separated from the passenger compartment.

According to a further embodiment, the air conditioning device has a temperature control unit separate from the air conditioner for controlling the temperature of coolant, a coolant supply line and a coolant return line, the coolant supply line and the coolant return line fluidically connecting the temperature control unit to the air conditioning unit, in particular the at least one heat exchanger. The air conditioning device forms a coolant circuit.

In particular, the temperature control unit is arranged below the longitudinal axis and / or spatially separated from the air conditioning unit. As a result, the temperature of the coolant necessary for conditioning the air in the air conditioner takes place in an area remote from the air conditioner, in particular from the passenger compartment, whereby the noise and thermal emissions in the area of the air conditioner, in particular in the area of the passenger compartment, can be reduced.

Furthermore, the object is achieved according to the invention by a vehicle which has a roof that delimits a passenger compartment and the air conditioning device according to the invention, the air conditioning device being attached to the roof. A reliable air flow to the passengers in the passenger compartment can thereby be guaranteed, since the air from the roof area is discharged uniformly and widely distributed into the passenger compartment and a direct air flow is made possible for lying passengers. In addition, due to the elongated extension of the air conditioning unit, free areas can be created laterally of the longitudinal axis of the air conditioning unit, which areas can be used, for example, for panoramic glazing of the roof.

In particular, the longitudinal axis of the air conditioner runs essentially in the longitudinal direction of the vehicle and / or the longitudinal axis lies in a vertical center plane which is parallel to the longitudinal direction of the vehicle. Uniform air conditioning of the vehicle can thus be achieved by the air conditioning device.

According to one aspect, the roof has a hollow longitudinal strut in which the air conditioner is at least partially, in particular completely, received. The longitudinal strut can serve as a cover, so that the air conditioner can be optically fitted into the passenger compartment.

The longitudinal strut can represent part of a roof lining of the vehicle, whereby the roof can be stabilized by the longitudinal strut.

The longitudinal strut preferably extends in the longitudinal direction of the air conditioner. In this way, the air conditioner can be completely accommodated in the longitudinal strut.

One aspect provides that the vehicle has at least one condensate discharge channel which runs along and / or in the A-pillar, the B-pillar, the C-pillar and / or the D-pillar, in particular wherein the vehicle has four condensate discharge channels, wherein two of the condensate discharge channels run along the A-pillar and two of the condensate discharge channels run along the C-pillar or the D-pillar. In this way, the condensate formed in the heat exchanger can be discharged from the air-conditioning unit in a controlled manner, whereby an uncontrolled collection of liquid in the air-conditioning unit can be prevented.

In particular, the A-pillar, the B-pillar, the C-pillar and / or the D-pillar form the condensate discharge channels. By utilizing the interior of the A-pillar, the B-pillar, the C-pillar and / or the D-pillar, installation space and material for an additional separate condensate discharge channel can be saved.

It can be provided that the condensate line of the air conditioner, the coolant supply line, the coolant return line and / or the air supply duct run or run through the condensate discharge ducts. In this way, the space within the condensate discharge channels can be optimally used.

In a further embodiment, the air supply device is provided in the rear of the vehicle or in the front of the vehicle and / or the temperature control unit is provided in the rear of the vehicle or in the front of the vehicle. As a result, acoustic and thermal emissions emanating from the air supply device and / or from the temperature control unit can be kept away from the passenger compartment.

In particular, the A-pillar, the B-pillar, the C-pillar and / or the D-pillar form an air supply duct which fluidly connects the air supply device to the air conditioning unit. In this way, the air required for air conditioning the passenger compartment can be conveyed to the air-conditioning unit from an area that is spatially separated from the passenger compartment. In addition, by using the interior of the A-pillar, the B-pillar, the C-pillar and / or the D-pillar as an air supply duct, installation space and material for an additional separate air supply duct can be saved.

Another embodiment provides that the vehicle has at least one wheel arch, the supply fan being arranged in the wheel arch and / or being designed to suck in air from the wheel arch. This takes place Sucking in the air in an area remote from the air conditioner, in particular from the passenger compartment, whereby the noise emission in the area of the air conditioner, in particular in the area of the passenger compartment, can be reduced.

The air conditioning device is preferably designed for ventilation, heating, cooling, humidification and / or dehumidification of the air in the passenger compartment of the vehicle. Comprehensive air conditioning of the passenger compartment can thus be made possible, as a result of which the comfort in the vehicle can be increased considerably.

The described advantages and properties of the air conditioning device according to the invention apply equally to the vehicle and vice versa.

It is conceivable that the A-pillar 3 who have favourited B-pillar 5 who have favourited C-pillar 7th and / or the D-pillar 8th at least part of the supply channels 18th form.

The air conditioner is optional 12th with a position sensor 21 coupled, through which a seat position and / or the presence of a passenger or several passengers in the passenger compartment can be detected.

In 3 and 4th is a first embodiment of the air conditioning device 10 , especially the air conditioner 12th shown. Here the longitudinal axis points 20th of the air conditioner 12th a curvature.

The air conditioner 12th includes two fans 22a , 22b a heat exchanger 24 , two air outlet ducts 26a , 26b an air supply duct 28 as well as four air outlets 30a , 30b .

The air outlet ducts 26a , 26b end in the corresponding air outlets 30a , 30b .

The blowers 22a , 22b are for example radial fans.

The first blower 22a is with the heat exchanger 24 , the first air outlet duct 26a , the air supply duct 28 and the first air outlets 30a directly fluidly connected.

In this context, directly fluidic means that no further blower is interposed.

The heat exchanger 24 closes directly on the first fan 22a , on the first air outlet duct 26a and on the air supply duct 28 at. It is provided that the on the heat exchanger 24 subsequent channel directly into the first air outlet channel 26a and the air supply duct 28 divides.

It can also be provided that the first air outlet duct 26a at the same time the air supply duct 28 forms.

Fluidically between the air supply duct 28 and the second air outlet duct 26b is the second blower 22b switched. The second fan 22b is directly with the second air outlet duct 26b and the second air outlets 30b fluidically connected.

The second air outlet duct 26b closes directly on the second fan 22b and divides towards its end like scissors, whereby it into the second air outlets 30b ends.

Such a scissors-like division can also be used in the case of the first air outlet duct 26a be provided.

Optionally, between the second fan 22b and the second air outlet duct 26b a second heat exchanger can be arranged.

The first and second air outlets 30a , 30b are elongated. This means that the longitudinal extension of the air outlets 30a , 30b , in particular an opening of the air outlets 30a , 30b , is greater than its transverse extent or the transverse extent of an opening of the air outlets 30a , 30b . For example, the ratio of length to transverse extent 5 to 1 .

The individual components of the air conditioner described above 12th are based on the longitudinal axis 20th , arranged essentially one behind the other. In other words, the individual components of the air conditioner 12th essentially a longitudinal arrangement that is parallel to the longitudinal axis 20th is.

Partly are the individual components of the air conditioner 12th , for example the first air outlet duct 26a and the air supply duct 28 , also arranged one above the other.

On the heat exchanger 24 , and optionally on the other heat exchanger, close a coolant supply line 32 , a coolant return line 34 and a condensate line 36 at. These can be part of the supply channels 18th be.

With an air conditioner 12th with two heat exchangers is a lateral offset between a condensate drain of a heat exchanger and the condensate line 36 provided, whereby a return of the condensate from one heat exchanger in the other heat exchanger is prevented.

The condensate line 36 splits in the area of the A-pillar 3 and the C-pillar 7th each in two sub-lines 36a , 36b on, with the sub-lines 36a , 36b like in the 1 and 2 shown, each by the A-pillars 3 and the C-pillars 7th extend.

Of course, the condensate line can 36 in the area of other components in two sub-lines each 36a , 36b split, for example in the area of the B-pillar 5 and the D-pillar 8th , with the sub-lines 36a , 36b then through the B-pillars 5 and the D-pillars 8th extend.

The partial lines 36a , 36b therefore initially run away from each other.

On the heat exchanger 24 or on the first fan 22a closes an air supply duct 38 at. At the other end of the air supply duct 38 is the air supply device 14th connected.

The air supply device 14th essentially comprises an external supply fan 40 and an intake manifold 42 , which is fluidically connected to the supply fan 40 connected is.

The conditioned air then flows on the one hand via the first air outlet duct 26a to the first air outlets 30a where the air enters the passenger compartment of the vehicle 1 is left out.

On the other hand, the air flows through the air supply duct 28 to the second fan 22b .

Optionally, the air then flows into a second heat exchanger.

After that, the air is released through the second air outlet duct 26b to the second air outlets 30b where the air enters the passenger compartment of the vehicle 1 is left out.

Accordingly, a fan, a heat exchanger, an air outlet duct and two air outlets form a unit which is each assigned to a row of seats in the vehicle and supplies the row of seats with conditioned air.
