Description

Air conditioning and air guiding device for a motor vehicle

The invention relates to a motor vehicle with an air conditioner having at least one positioned in a storage space of the motor vehicle cooling and / or heating unit and at least one air guide device which is coupled to an air conditioning air interface of the cooling and / or heating unit, with energy required for cooling purposes an internal combustion engine of the motor vehicle is provided.

The invention further relates to an air conditioning system and an air guiding device.

The air conditioning of motor vehicles is becoming increasingly important. In addition to the usual vehicle heaters, most of which draw heat energy from the cooling circuit of the internal combustion engine of the motor vehicle, combustion engine-independent heating units are also increasingly used as so-called supplementary heaters, heaters or auxiliary heaters. Also, the technology for cooling of vehicle interiors is well advanced, in which here in particular powered by a powered by the internal combustion engine of the vehicle compressor, equipped with a condenser and an evaporator air conditioning systems have become almost the standard in the automotive industry. For various reasons, it is increasingly deviated from the concept of equipping motor vehicles exclusively with an air conditioning system arranged in the front region. For example, stationary air conditioners can also be arranged in the trunk of the vehicle. In this context, then the task to be solved, the generated by the stationary air conditioning cold air in to transport the vehicle interior. It has already been proposed to realize this via long air hoses, which lead into the roof area of the motor vehicle, in which case the air enters the vehicle interior via air vents introduced into the interior trim or an air-permeable headliner. However, this has the disadvantage that long distances are required, which must flow through the cold air before it is used in the interior. This leads to a considerable heating of the cooling air. At high outside temperatures, air that is cooled down to about 0 ⁰ C in the trunk, then, when it enters the roof of the vehicle in the vehicle interior, already heated to 15 ⁰ C. Consequently, the efficiency of air conditioning is lowered.

The invention has for its object to provide a concept for the supply of cooling and / or heating air in a vehicle interior, which avoids the disadvantages described and on the basis of a simple retrofitting ability of motor vehicles is made possible.

This object is achieved with the features of the independent claim.

Advantageous embodiments of the invention are indicated in the dependent claims.

The invention is based on the generic motor vehicle in that the air-guiding device has a built-up on a wall bounding the passenger area, at least partially in the passenger area of the motor vehicle. ordered air duct with at least one opening into the passenger area air outlet opening and that the air duct extends into the storage space, where it is coupled to the air conditioning air interface. Such an air duct can be mounted in a simple and cost-effective manner in a motor vehicle, in particular, the retrofitting of a motor vehicle on this basis is completely unproblematic. The air duct is mounted in the passenger area without requiring special changes to the equipment of the motor vehicle. The air duct protrudes into the storage space, in which the cooling and / or heating unit is arranged. Long, lossy paths of tempered air can thus be avoided.

Usefully it can be provided that the cooling and / or heating unit is arranged in the direction of travel of the motor vehicle behind the passenger area. In this area, storage spaces are available for many vehicles, which allow the unit to be accommodated. In the context of the present disclosure, the term designates any free space in the motor vehicle, regardless of whether access to this free space is usually possible.

Usefully, it is provided that the cooling and / or

Heating unit has an electrically operable compressor, which is arranged in a refrigerant circuit, and the air conditioning air interface of an evaporator of the refrigerant circuit cooled air can be fed. In conventional systems, it is provided to transport the cooled air into the region of the vehicle roof and there, for example, se through the headliner into the interior. At high outside temperatures, this can lead to a considerable loss of efficiency of the air conditioning, as the air heats considerably on their way from the unit into the interior, without significantly removing the heat energy required for this purpose the interior of the vehicle. This is avoided by the present invention, because the cold air is fed by the shortest route still in the storage space of the motor vehicle in the air duct, which it then flows through directly to finally be able to flow into the vehicle interior.

With regard to the heating function, it is possible that the air conditioning air interface waste heat can be supplied, which arises during operation of the cooling and / or heating unit.

This is an example of the heating of a motor vehicle that does not require heating elements, which are designed specifically for heating. On the contrary, the inevitable waste heat of the cooling and / or heating units can make an additional heat source superfluous.

Usefully, it is provided that the storage space is a partial area of a trunk of the motor vehicle. In large vehicles, the trunk provides sufficient space to accommodate a cooling and / or heating unit. This is especially true for luxury sedans, especially since there the boot is hardly used anyway for time-consuming transport purposes.

The housing of the cooling and / or heating unit can for example be such that the cooling and / or heating unit below a horizontal loading area of the case is arranged space. The cooling and / or heating unit can be accommodated in this way completely or almost invisible in the trunk. Nevertheless, a loading area offers the possibility of accessing the unit, for example for maintenance or repair purposes, by making the loading area pivotable and / or displaceable.

It is also possible that the cooling and / or heating unit in the direction of travel of the motor vehicle in front of a substantially vertical, perpendicular to the direction of travel of

Motor vehicle arranged trunk separation is arranged. The trunk is therefore only slightly shortened in this way, which in turn is completely unproblematic, especially in large luxury sedans.

Usefully, it is provided that the air duct extends through a recess of the parcel shelf in the storage space. Such a recess can be introduced without problems into a parcel shelf, for example on a corner of the parcel shelf facing the rear seat backrest. On this basis, the air duct can then rest anywhere in the interior of the vehicle on the inner lining, so that ultimately represents the introduction of the recess in the parcel shelf, the only or almost the only intervention in the existing interior equipment of the motor vehicle in terms of retrofitting of motor vehicles.

But it is also possible that the air duct projecting through covers a C-pillar in the storage space. Behind such covers can be found in numerous

There is still room for vehicles to enter the air duct. bring. In particular, the path of the air duct from the passenger compartment into the storage space is thus covered by an already existing cover of the motor vehicle, which makes any irreversible change of the vehicle interior unnecessary.

According to a particularly preferred embodiment of the invention it is provided that the air duct surrounds a rear window of the motor vehicle laterally and above. One of the lateral sections of the air ducting projects into the storage space. The air flows via this section into the air duct, then along the rear window, and then flows down over the remaining side section, which is preferably closed at the end. It is also possible to supply the air from both ends of the air duct to flow in. In any case, it is possible to introduce the cold air in the upper areas of the interior. This has particular advantages with regard to the cooling of the vehicle interior, since the introduction of cold air into upper regions ensures good mixing of the entire interior volume. It is also not necessary to pass cold air on the hot rear window of the motor vehicle before it reaches the interior.

According to one embodiment of the present invention can be provided that the air duct is at least partially attached to a rear window of the motor vehicle. It is also possible that the air duct is at least partially attached to a rear window of the motor vehicle.

It is also possible that the motor vehicle has a trunk which is not separated from the passenger compartment by a parcel shelf and that a substantially vertical, arranged perpendicular to the direction of travel of the motor vehicle partition is provided which thermally and acoustically decouples the passenger compartment of the trunk. In so-called combined vehicles or even in the increasingly widespread SUV vehicles and off-road vehicles, the trunk is not separated from the passenger compartment of the motor vehicle. In this context, it is particularly useful to make a separation when such a motor vehicle is to be equipped in accordance with the invention. This prevents unwanted transfer of waste heat of the cooling and / or heating unit in the passenger compartment, and disturbing noises caused by the operation of the cooling and / or heating unit, get in this way, or only reduced in the passenger compartment.

For example, it can be provided that the partition wall is transparent. The partition can thus be realized in particular as a glass or acrylic glass.

In this context, it can be provided that the air duct framed the partition sideways and above. With regard to the partition wall in a station wagon, an SUV vehicle or even an off-road vehicle, the same arrangements are therefore possible, as with a rear window of a normal sedan.

For example, it may be provided that the air duct is at least partially attached next to the partition wall.

It is also possible that the air duct is at least partially attached to the partition wall.

According to a further preferred embodiment it can be provided that the dividing wall is removable. This allows in particular the loading of larger items in the passenger compartment. For example, the partition is pulled down behind the rear seat backrest to remove it. If the air duct is attached to the partition, then this is also retracted with the hose connections of the air duct with the cooling and / or heating unit must then be routed so that a ne lowering of the air duct is readily possible.

It is also possible that a roller blind is arranged on the air duct, wherein electric motors are arranged in the air duct for driving the roller blinds. In particular, when the air duct is arranged in the region of the rear window or a partition wall, it makes sense to provide this at the same time as a holder for a roller blind. When retrofitting vehicles for hot regions, one intended primarily for refrigeration purposes

Air duct in combination with a sunblind be offered. The electric motors that operate the roller blind are arranged invisibly in a useful manner in the air duct. The electrical feeds to the electric motors can be placed easily in the air duct.

It is preferred that the air duct is at least partially attached by means of at least one Velcro strip on the motor vehicle.

It can also be provided that the air duct is at least partially adhered to the motor vehicle.

Usefully, it is provided that the air duct is at least partially made of plastic.

Furthermore, it may be advantageous that the air duct is at least partially made of thermally insulating foam. A thermal insulation of the air duct should be provided in particular in the direction of the outside of the vehicle in order to prevent a thermal interaction of the air duct with the air flowing through the air duct in this area as possible.

In this context, it is also possible that the air duct is internally coated at least partially with a metallic foil.

According to a preferred embodiment of the present invention, it is provided that the air duct is in one piece. A one-piece design of the air duct nals is ideal if a large number of channels is to be used in identical vehicles. The air duct is then adjusted exactly to the required degree.

It is also possible that the air duct is multi-part.

This has advantages in connection with the fact that the air duct has a first shell connected to the motor vehicle and a second shell connected to the first shell. By making the switches separable, access to the interior of the air duct can be allowed in this way, and cables and other components can be conveniently installed during assembly.

However, the multi-part design of the air duct can also be advantageous in the context that the air duct has a plurality of channel sections which follow one another in the flow direction of the air. The air ducts can then be designed in particular shortened, wherein lateral sections of the air duct are connected to the upper portion of the air duct via corner elements.

Furthermore, it is particularly preferred that the air duct on at least one of a motor vehicle side mounting surface facing edge has a flexible reinforcement, the eventual distances between the air duct tion channel and the mounting surface laminated or compensated. Such a flexible reinforcement will also called piping. As a result, a visually perfect impression is provided.

It is further provided that the air duct has a rear surface used as a fastening surface, an opposite front surface and two side surfaces, wherein the side surfaces perpendicular to the flow direction of the air have a smaller dimension than the rear surface and the front surface. Such a flat air duct is particularly inconspicuous.

It is preferred that the front surface has a plurality of air outlet openings.

Alternatively or additionally, it can be provided that at least one side surface has a plurality of air outlet openings. While the air outlet openings on the front surface, in the first place, allow the direct inflow of air into the vehicle compartment particularly well, air outlet openings arranged on the side surfaces can have further positive effects. For example, such air outlet openings may be directed towards the rear window, so that this can be de-iced in a very short time. The air outlet openings can also be replaced or supplemented by one or more slots extending along the air duct.

It is particularly advantageous that the air outlet openings are at least partially adjustable with respect to the Luftausströmrich- and / or the Luftausströmrate. Alternatively or additionally, it may be provided that a fan is provided, with the air in the air duct is insertable, wherein the fan has a variable speed.

According to further preferred embodiments, it is provided that electrically controllable components are integrated into the air duct.

In this context, it is advantageous that in the air duct a receiver is integrated, which is suitable to receive a signal from a remote control, wherein the receiver is connected via a guided in the air duct conduit connection with a control unit of the cooling and / or heating unit. The cooling and / or heating unit must always be operable. It offers an operation from the vehicle interior, but this must be easily accessible. About the air duct, a receiver for receiving signals from a remote control can easily bring into the vehicle interior and connect completely unproblematic about lying in the air duct cable connections with the control unit of the cooling and / or heating unit. The hand-held transmitter can also be additionally equipped as a receiver and communicate with a transmitter arranged in the air duct, which can also be implemented in a structural unit with the receiver. In this way, information on the cooling and / or heating unit or other information can be displayed on a display of the remote control. It can also be provided that electrically operable heating elements are arranged in the air duct. This is a useful variant for heating the vehicle interior.

Alternatively or additionally, it is possible for air heated by the air-conditioning air interface to be supplied by an electrically operable heating element.

In addition to the introduction of air conditioning air over the air duct, it can be provided that at least one Luftausströmöffnung is arranged in a parcel shelf of the motor vehicle, which is in communication with the air conditioning air interface.

The invention further consists in an air conditioning system and an air duct, which are suitable to be used in a motor vehicle.

Also, the invention consists in an air duct, which is suitable to be used in a motor vehicle.

The invention will now be described by way of example with reference to the accompanying drawings by way of particularly preferred embodiments. Show it :

In the following description of the drawing, like reference numerals describe the same or similar components.

Figure 1 shows a schematic representation of the rear

Area of a motor vehicle for explaining a first embodiment of the invention. In the illustration of Figure 1, the view is directed from the inside to the rear window 34 of a motor vehicle. Above the rear window 34, a part of the vehicle roof 72 can be seen. Below the rear window 34 is the parcel shelf 30. Side of the Rear window 34, the panels of the C-pillar 32 can be seen. In the trunk of the motor vehicle, that is, in particular behind the rear seat 74 and below the parcel shelf 30, there is a cooling and / or heating unit 10. The rear window 34 is laterally and above framed by an air duct 12 which extends through the parcel shelf 30 into the storage space in which a cooling and / or heating unit 10 is arranged. The air guide frame 12 may be in communication with both of its open ends to the cooling and / or heating unit 10. It is also possible to close the air guide frame 12 at one end and connect only with an open end to the cooling and / or heating unit 10. The coupling of the air guide frame 12 with the cooling and / or heating unit via simple hoses. Alternatively to the implementation of the air guide frame 12 through the parcel shelf 30 may be provided to conceal this with the covers of the C-pillar 32 and then pass laterally past the parcel shelf 30. The air guidance frame 12 is thus in communication with an air conditioning air interface 14 of the cooling and / or heating unit 10, which has a preferably speed-controllable and / or controllable fan 64 in order to supply air conditioning air into the air guide frame 12 with this fan 34 entered. At the same time the fan 24 sucks air from the storage space in which the cooling and / or heating unit 10 is arranged. Within the cooling and / or heating unit 10 there is furthermore a control unit 22 for the cooling and / or heating unit 10, a cooling circuit 28 which in particular comprises a compressor, an evaporator and a condenser. points, as well as other components 20, which are required for the operation of the unit provided. The air introduced by the blower 64 into the air guide frame 12 can flow into the vehicle interior via air outlet openings 16, the air outlet openings preferably being adjustable in their outflow direction and with regard to the outflow rate. In the presently described exemplary embodiment, the air outlet openings 16 are arranged in the front side 60 of the air guide frame 12. For cooling the motor vehicle, the cooling circuit 28 can be operated so that cold air can be introduced into the air guiding frame 12 and thus into the vehicle interior via the air conditioning air interface 14. It is also possible to heat the motor vehicle with the described arrangement, namely using waste heat, which in the

Cooling and / or heating unit 10 is generated. Furthermore, an electrical heating element 70 is arranged in the region of the air-conditioning air interface 14, so that electrically heated air can be introduced into the vehicle interior via the air duct 12. In the present embodiment, the air guide frame 12 of a first shell 44 which is fixed to the motor vehicle, and a second shell 46, which is attached to the first shell 44, constructed. It is also possible to carry out the air duct 12 completely in one piece. The assembly of the air duct 12 on the inner panel or the rear window 34 of the motor vehicle via a Velcro connection, one component with the vehicle and the other component with the air duct frame firmly, for example, by gluing, is connected. It is also possible, the air guide frame 12 directly to stick the vehicle. The air duct 12 is preferably made of plastic or insulating foam. It may be completely or partially coated on the inside with a metal foil.

Figure 2 shows a schematic representation of the rear portion of a motor vehicle for explaining a second embodiment of the invention. Here, in addition to the air outlet openings 16 provided on the front surface 60, the air guide frame 12 is provided with air outlet openings 18 arranged on a side surface 62, a plurality of these air outlet openings 18 being provided. On the other side surfaces of the air duct 12 may also be provided air outlet openings, in particular also on the side surfaces which face the rear window 34. By this the rear window 34 facing air outlet openings, the rear window 34 can be quickly de-iced during heating. In the air duct 12, a roller blind 40 is further integrated, which is shown here in partially extended state. For operating the roller blind 40 electric motors 42 are provided, which are arranged within the air duct 12. The electrical control of these electric motors 42 preferably takes place via lines which are guided inside the air duct. In the air duct 12 further electrical components are arranged, namely heating elements 76. These are also operated via electrical lines which are arranged in the air duct. Through the air duct 12 and the adjoining hoses, the electrical lines can be guided to the control unit 68. While the electric motors 42 and the thermocouples 76 provided for heating the air flowing through the air duct 12 are housed invisibly in the air duct 12, a receiver 66, which is preferably equipped as an infrared sensor, visible on the air duct 12 is arranged. This is also connected via line connections to the control unit 68 of the cooling and / or heating unit 10 in connection. The receiver 66 receives from a hand-held transmitter, not shown control signals and transmits them to the control unit 68 of the cooling and / or heating unit. In this way, a convenient operation of the cooling and / or heating unit 10 can be accomplished from any point of the vehicle interior, without the need for a complex wiring would be required. The only cables are routed in the air duct 12, which is completely unproblematic. In addition to a visible on the surface of the air duct 12 infrared sensor 66 and other types of receiver may be provided, in particular those for which no visual connection with the transmitter is required. Also, a transmitter may be provided in the region of the air duct 12, in particular in structural unit with the receiver 66. In this way, information to the remote control, which must then also have receiver functions are transmitted, so that they are displayed on a display of the remote control can be, for example, temperature information.

Figure 3 shows a schematic representation of the rear portion of a motor vehicle for explaining a third embodiment of the invention. The air duct 12 is here from several sections 48, 50, 52, 54, 56 constructed, which follow one another in the flow direction of the air conditioning air. On this basis, it is possible to very flexibly equip various vehicles with the air duct 12 according to the invention, since the lateral parts 48, 56 and the upper part 52 can easily be brought to a suitable length, and then only via the corner parts 50, 54 to be connected. In order to hide any distances between the air duct 12 and the inner lining of the motor vehicle, a flexible reinforcement 58, a so-called piping, can be arranged on any sides of the air duct 12 which are intended to rest against the inner lining.

Figure 4 shows a sectional view through the trunk of a motor vehicle according to the invention. It can be seen that the cooling and / or heating unit 10 is arranged behind the backrest 74 of the rear seat in the trunk 24 below the parcel shelf 30. In order to conceal the cooling and / or heating unit when accessing the trunk space 74, a substantially vertically oriented dividing wall 28 is provided, which extends over the entire width or over only a part of the width of the trunk 24. According to other embodiments can be provided to place the cooling and / or heating unit visible in the trunk, especially if this has a high-quality and attractive design.

FIG. 5 shows a side view of another motor vehicle according to the invention. It is a motor vehicle shown, the trunk 24 is not normally from the Passenger area 38 is separated, as is common in station wagons, SUV vehicles and SUVs. Even with such vehicles, it is possible to arrange the cooling and / or heating unit 10 in the trunk 24, here for example below a horizontal loading area 26 of the trunk, possibly next to or above or below the spare wheel. Access to the cooling and / or heating unit 10 is provided by an extendability or a pivotability of the loading area 26. In order to provide acoustic and thermal decoupling between the trunk 24 and the passenger compartment 38, a transparent partition 36 is provided between these areas. The air duct, not shown here, can then be arranged with respect to the transparent partition 36 in a comparable manner, as with respect to the rear window in a sedan.

In addition to the air cooling or air heating via the air duct, it may also be provided to couple the cooling and / or heating unit with the cooling circuit of the internal combustion engine. The introduced into the interior air is then controlled indirectly via the coolant by heat exchangers of the conventional vehicle air conditioning system can be used.
