Description

Air conditioner and vehicle

Technical Field

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

Background

The task of an air conditioning device in a vehicle is to condition, in particular heat or cool, and purify the air in the passenger compartment of the vehicle.

For this reason, conventional air conditioning devices have an air conditioner which is usually arranged in the cockpit area of the vehicle. The conditioned air may be discharged into the passenger compartment through an air outlet in the cockpit area. The air outlet may be manually or automatically adjusted to enable air to flow directly to the seated passenger.

Conventional air conditioning units, and in particular conventional air conditioners, are relatively large and bulky and therefore occupy a lot of installation space in a vehicle. As more and more electronic devices, in particular comfort systems and multimedia systems, are integrated, in particular the installation space in the cockpit area is becoming smaller and smaller, the integration of air conditioners in the cockpit area becomes more and more difficult.

With increasing (partial) automation of the vehicle, the seating position is also more variable, so that air must be able to flow to the seated and lying passengers. It is not possible with conventional air conditioning devices (in which air flows to the passengers through air outlets in the cockpit area) to achieve a sufficient air flow to the lying passengers.

Disclosure of Invention

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

According to the invention, the object is achieved by an air conditioning device for air conditioning a passenger compartment of a vehicle, comprising an air conditioner having a longitudinal axis and at least one blower device, at least one heat exchanger and at least one air outlet channel, the air outlet channel having a plurality of air outlets, the blower device, the heat exchanger, the at least one air outlet channel and the air outlets being arranged along the longitudinal axis. Due to its slim design and extension, the air conditioner is designed to be compact, particularly in the lateral direction, so that it has a completely different size from a conventional air conditioner. Thus, the air conditioner may be installed in other areas of the vehicle, such as the roof area, which have not been considered for air conditioners so far.

The longitudinal axis may form a central axis of the vehicle. Thus, uniform air conditioning of the vehicle interior space can be achieved by the air conditioning device or the air conditioner.

By "along the longitudinal axis" is understood, for example, that the respective components run largely parallel, if necessary taking into account the curvature of the longitudinal axis.

Optionally, the longitudinal axis may have a curvature. The air conditioning device, in particular the air conditioner, can thus be adapted to the specific shape and structure of the vehicle components, such as the interior of the vehicle roof.

The individual components of the air conditioner are also arranged one above the other, in particular with respect to the longitudinal axis. In other words, the respective components of the air conditioner are disposed substantially vertically in addition to the longitudinal arrangement. In this way, the air conditioner can be configured to be narrow in the lateral direction with respect to the longitudinal axis.

Preferably, the various components of the air conditioner are not disposed laterally side-by-side about the longitudinal axis. For example, the components extend mainly parallel to the longitudinal axis. In this way, the air conditioner can be configured to be narrow in the lateral direction with respect to the longitudinal axis.

An embodiment provides that the at least one air blowing device is in fluid connection with the plurality of air outlets of the at least one air outlet channel, the at least one heat exchanger being arranged between the air blowing device and the plurality of air outlets. The blower device serves as a blower device, by means of which the heat exchanger is charged with air and heats or cools the air. Therefore, the heat exchanger has a function of air heating or air cooling. The heated or cooled air can flow out of the air outlet in a targeted manner into a specific region of the passenger compartment or diffusely into the passenger compartment of the vehicle. Thereby, air conditioning of the passenger compartment can be achieved.

In particular, the blower device, the heat exchanger and the air outlet channel form a unit which is assigned to the respective row of seats of the vehicle. In this way, heated or cooled air can be discharged in a targeted manner into a seat row in the vehicle.

In a further embodiment, two air outlet channels are provided, one blowing device being in direct fluid connection with both air outlet channels, or two blowing devices being in direct fluid connection with one air outlet channel each. The component and production costs can be reduced by an arrangement with only one blower device. In an arrangement with two air blowing devices, smaller air blowing devices can be used and reliable air supply to the heat exchanger and the air outlet over a longer distance can be ensured.

In particular, the air discharge channel and the blowing device are arranged in succession on the longitudinal axis. In this way, a narrow overall shape of the air conditioner can be ensured.

The blowing device is, for example, a radial blowing device. The radial blower device may have outlets offset by 180 °, both outlets lying on the longitudinal axis and each connected to an air outlet channel.

According to one aspect, the air conditioner has an air supply duct which extends along the longitudinal axis and is in fluid connection with one of the at least one blowing devices, in particular the air supply duct extends between two of the blowing devices. By means of this air supply channel, the intake of the required air can be spatially separated from the air conditioner and the noise emission in the area of the air conditioner can therefore be reduced.

It can be provided that the air outlet duct of the blower device assigned to the air outlet duct is simultaneously the air supply duct of a further blower device assigned to the air supply duct. In this way, an additional air supply channel can be dispensed with and the number of components can therefore be reduced.

In particular, the air supply channel is arranged above or below one of the at least one air outlet channel. Thus, the air delivery passage is not disposed laterally next to other components of the air conditioner, whereby the width of the air conditioner can be reduced in a lateral direction with respect to the longitudinal axis.

Preferably, the air outlet is configured to be elongate, the air outlet extending along a longitudinal axis. Thus, the height of the air outlet and thus of the air conditioner can be kept low with respect to the longitudinal axis, while ensuring the air volume flow required for air conditioning the passenger compartment. Therefore, it is also possible to widen the area in the passenger compartment into which the airflow flows and ensure comfortable airflow.

The elongate extent here means a longitudinal extent which is greater than the transverse extent of the air outlet, in particular at least 5 times greater.

On the other hand, it is provided that the outflow direction of the air from the air outlet can be adjusted manually and/or automatically. Thus, an optimized flow of air to a specific area in the passenger compartment can be achieved.

Alternatively, the air conditioner or air conditioning device may be coupled to a location identification system. Thereby, the position of the passenger in the passenger compartment can be detected and the outflow direction of air from the air outlet can be automatically controlled based on the position information.

In one embodiment, the air conditioner has a condensate line which extends along the longitudinal axis and is connected to the at least one heat exchanger for receiving condensate, in particular the condensate line is arranged laterally offset relative to the at least one heat exchanger with respect to the longitudinal axis or extends below the at least one heat exchanger. In this way, the condensate formed in the heat exchanger can be removed from the air conditioner in a controlled manner, as a result of which uncontrolled accumulation of liquid in the air conditioner can be prevented.

Preferably, a misalignment is provided between the condensate outlet of a heat exchanger and the condensate line. This offset prevents condensate from flowing back into another heat exchanger which is also fluidically connected to the condensate line.

In a further embodiment, it is provided that the air conditioning device has an air supply device with at least one supply blower device and at least one air supply channel, the at least one supply blower device being arranged below the longitudinal axis of the air conditioner, and the at least one air supply channel fluidically connecting the at least one supply blower device to the air conditioner, in particular to the air supply channel. Thus, the air required for air-conditioning the passenger compartment can be delivered to the air conditioner from an area spatially separated from the passenger compartment.

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

In particular, the temperature conditioning assembly is disposed below the longitudinal axis and/or is spatially separated from the air conditioner. Thus, the temperature regulation of the coolant required for the regulation of the air in the air conditioner takes place in an area remote from the air conditioner, in particular from the passenger compartment, so that noise and heat emissions in the area of the air conditioner, in particular in the area of the passenger compartment, can be reduced.

Furthermore, according to the invention, the object is achieved by a vehicle comprising a roof delimiting a passenger compartment and an air conditioning device according to the invention, the air conditioner being fastened to the roof. Since the air is discharged uniformly and widely distributed from the roof region into the passenger compartment and a direct flow of air to the lying passengers is also possible here, a reliable flow of air to the passengers in the passenger compartment can be ensured. In addition, due to the elongate extension of the air conditioner, free areas can be provided transversely to the longitudinal axis of the air conditioner, which can be used, for example, for panoramic glass of a vehicle roof.

In particular, the longitudinal axis of the air conditioner extends substantially in the vehicle longitudinal direction and/or the longitudinal axis lies in a vertical center plane parallel to the vehicle longitudinal direction. Thus, a uniform air conditioning of the vehicle can be achieved by the air conditioning device.

According to one aspect, the roof has a hollow longitudinal strut into which the air conditioner is at least partially, in particular completely, received. The longitudinal struts can serve as covering elements, whereby the air conditioner can be visually adapted to the passenger compartment.

The longitudinal struts can form part of the roof of the vehicle, whereby the roof can be stabilized by the longitudinal struts.

Preferably, the longitudinal stay extends in a longitudinal direction of the air conditioner. In this way, the air conditioner can be completely received in the longitudinal stay.

In one aspect, it is provided that the vehicle has at least one condensate outlet channel which extends along and/or in the a, B, C and/or D column, in particular that the vehicle has four condensate outlet channels, two of which extend along the a column and two of which extend along the C or D column. In this way, the condensate formed in the heat exchanger can be removed from the air conditioner in a controlled manner, so that an uncontrolled accumulation of liquid in the air conditioner can be prevented.

In particular, the column a, column B, column C and/or column D form the condensate outlet channel. By using the interior space of the a, B, C and/or D columns, installation space and material for additional separate condensate discharge channels can be saved.

Provision may be made for the condensate line, the coolant supply line, the coolant return line and/or the air supply channel of the air conditioner to extend through the condensate outlet channel. Thus, the space within the condensate outlet channel can be optimally utilized.

In another embodiment, the air supply device is arranged in the vehicle rear or in the vehicle head, and/or the temperature regulating assembly is arranged in the vehicle rear or in the vehicle head. Thereby, the acoustic and thermal emissions emanating from the air supply and/or the temperature regulating assembly can be kept away from the passenger compartment.

In particular, the a, B, C and/or D columns form an air supply channel that fluidly connects the air supply with the air conditioner. Thus, the air required for air-conditioning the passenger compartment can be delivered to the air conditioner from an area spatially separated from the passenger compartment. Furthermore, by using the inner space of the a-pillar, the B-pillar, the C-pillar, and/or the D-pillar as the air supply channel, installation space and material for an additional separate air supply channel can be saved.

Another embodiment provides that the vehicle has at least one wheel cover, in which the supply blower is arranged and/or is designed to suck in air from the wheel cover. In this way, the air intake takes place in a region remote from the air conditioner, in particular from the passenger compartment, so that the noise emission in the region of the air conditioner, in particular in the region of the passenger compartment, can be reduced.

Preferably, the air conditioner is configured for ventilation, heating, cooling, humidification and/or dehumidification of air within a passenger compartment of a vehicle. From this, can realize the comprehensive air conditioning to passenger compartment to the travelling comfort in the vehicle can be greatly improved.

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

Detailed Description

Fig. 1 shows a vehicle 1 having an a-pillar 3, a B-pillar 5, a C-pillar 7, and a D-pillar 8, as well as a roof 9. The roof 9 delimits a passenger compartment of the vehicle 1.

An air conditioning apparatus 10 is installed in the vehicle 1 and includes an air conditioner 12, an air supply device 14, a temperature adjusting assembly 16, and a supply passage 18.

The air conditioner 12 is disposed on the vehicle roof 9 and in particular in the passenger compartment of the vehicle 1 and has a longitudinal axis 20 substantially parallel to the longitudinal axis of the vehicle 1.

The longitudinal axis 20 of the air conditioner 12 may also be curved, depending on the curvature of the roof 9.

For clarity, the vehicle 1 is shown in fig. 2 without the D-pillar 8.

The longitudinal axis 20 forms a longitudinally directed centre axis of the vehicle 1.

The air supply device 14 is arranged below the longitudinal axis 20 and in this embodiment is seated in the rear of the vehicle 1.

The temperature regulating assembly 16 is also arranged below the longitudinal axis 20 and in this embodiment is placed in the head of the vehicle 1.

Of course, the air supply device 14 and the temperature regulating assembly 16 may also be arranged in other regions of the vehicle 1 below the longitudinal axis 20.

The air conditioner 12 is fluidly connected to the air supply 14 and the temperature conditioning pack 16 by at least a portion of the supply passage 18. For example, the supply channels 18 include at least one air supply channel, at least one coolant supply line, at least one coolant return line, and/or at least one condensate line.

In the embodiment shown here, the supply channels 18 are provided in the a-pillar 3 and the C-pillar 7 of the vehicle 1.

Of course, the supply passage 18 may be provided in other members, such as the B-pillar 5 and the D-pillar 8.

It is contemplated that the a-column 3, B-column 5, C-column 7, and/or D-column 8 form at least a portion of the supply channel 18.

Optionally, the air conditioner 12 is coupled with a position sensor arrangement 21 by which the seating position and/or presence of a passenger or passengers in the passenger compartment can be detected.

Fig. 3 and 4 show a first embodiment of an air conditioning system 10, in particular an air conditioner 12. Here, the longitudinal axis 20 of the air conditioner 12 has a curvature.

The air conditioner 12 includes two

air blowing devices

22a, 22b, a heat exchanger 24, two

air discharge passages

26a, 26b, an air delivery passage 28, and four

air outlets

30a, 30 b.

The

air discharge channels

26a, 26b terminate in

respective air outlets

30a, 30 b.

The

blowing devices

22a, 22b are, for example, radial blowing devices.

The first air mover 22a is in direct fluid connection with the heat exchanger 24, the first air discharge passage 26a, the air delivery passage 28 and the first air outlet 30 a.

Direct fluid (connection) means in this connection that no further blowing device is connected in between.

The heat exchanger 24 is directly connected to the first air blowing device 22a, the first air discharge passage 26a, and the air delivery passage 28. In this case, the channels connected to the heat exchanger 24 are divided directly into a first air outlet channel 26a and an air supply channel 28.

It can also be provided that the first air outlet channel 26a simultaneously forms the air supply channel 28.

A second blower device 22b is fluidically connected between the air supply duct 28 and the second air outlet duct 26 b. The second air blowing device 22b is directly fluidly connected to the second air discharge channel 26b and the second air outlet 30 b.

A second air outlet channel 26b is connected directly to the second blowing device 22b and is divided in a scissor-like manner towards its end, which second air outlet channel ends in a second air outlet 30 b.

Such a scissors-like separating structure may also be provided in the first air discharge passage 26 a.

Alternatively, a second heat exchanger may be provided between the second air blowing device 22b and the second air discharge passage 26 b.

The first and

second air outlets

30a, 30b are configured to be elongated. This means that the longitudinal extent of the

air outlet

30a, 30b, in particular the longitudinal extent of the opening of the

air outlet

30a, 30b, is greater than its transverse extent or the transverse extent of the opening of the

air outlet

30a, 30 b. For example, a ratio of longitudinal extension to transverse extension of 5: 1.

the various components of the air conditioner 12 described above are arranged substantially in sequence about the longitudinal axis 20. In other words, the various components of the air conditioner 12 have a substantially longitudinal arrangement parallel to the longitudinal axis 20.

The various components of the air conditioner 12 are also partially disposed above one another, such as the first air discharge passage 26a and the air delivery passage 28.

A coolant supply line 32, a coolant return line 34 and a condensate line 36 are connected to the heat exchanger 24 and optionally to further heat exchangers. The coolant supply line, the coolant return line and the condensate line may be part of the supply channel 18.

In the air conditioner 12 having two heat exchangers, a lateral offset is provided between the condensate outflow portion of one heat exchanger and the condensate line 36, thereby preventing condensate from flowing back from one heat exchanger to the other heat exchanger.

The condensate line 36 is divided in the region of the a-column 3 and the C-column 7 into two

partial lines

36a, 36b, respectively, which

partial lines

36a, 36b extend through the a-column 3 and the C-column 7, respectively, as shown in fig. 1 and 2.

Of course, the condensate line 36 can also be divided into two partial lines 36a, 36B in the region of further components, for example in the region of the B-column 5 and the D-column 8, respectively, which partial lines 36a, 36B then extend through the B-column 5 and the D-column 8, respectively.

The sub-lines 36a, 36b thus extend first away from one another.

An air supply channel 38 is connected to the heat exchanger 24 or the first air blowing device 22 a. An air supply device 14 is connected to the other end of the air supply channel 38.

The air supply device 14 essentially comprises an external supply blower 40 and an air inlet connection 42, which is fluidically connected to the supply blower 40.

As shown in fig. 1 and 2, the air supply passage 38 extends through the C-pillar 7 of the vehicle 1. It can be provided that the C-pillar 7 forms an air supply channel 38.

In a vehicle 1 having a D-pillar 8, the air supply passage 38 may extend through the D-pillar 8 or the D-pillar 8 may form the air supply passage 38.

An external supply blower 40 is arranged, for example, next to the wheel housing and sucks in fresh air via an intake connection 42, for example, in the wheel housing region of the vehicle 1 and conveys it via the air supply duct 38 to the first blower 22 a.

In the case of sufficiently strong external supply blower 40, the first blower 22a and/or the second blower 22b can be dispensed with.

The air is then directed through the heat exchanger 24 where it is heated or cooled as needed. To this end, a coolant supply line 32 delivers hot or cold coolant from the temperature regulating assembly 16 to the heat exchanger 24, and a coolant return line 34 delivers cold or hot coolant from the heat exchanger 24 back into the temperature regulating assembly 16. A coolant circuit is thus formed, by means of which the conditioning of the air flowing through the heat exchanger 24 can be effected.

The condensate formed in the heat exchanger 24 is drawn off in a controlled manner via a condensate line 36.

Thus, the coolant supply line 32, the coolant return line 34, the condensate line 36 and the air supply channel 38 form the supply channel 18.

The conditioned air then flows on the one hand via the first air outlet channel 26a to the first air outlet 30a, where the air is discharged into the passenger compartment of the vehicle 1.

On the other hand, the air flows to the second air blowing device 22b through the air conveyance passage 28.

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

Thereafter, the air is guided to the second air outlet 30b via the second air discharge passage 26b, where the air is discharged into the passenger compartment of the vehicle 1.

Thus, one blower device, one heat exchanger, one air outlet channel and two air outlets form a unit which is assigned to each row of seats in the vehicle and supplies conditioned air to the row of seats.

To ensure optimal direct flow of air to passengers in any seating position, the air conditioner 12 may be coupled with a position sensor arrangement 21 (see fig. 2) by which the presence and/or seating position of a passenger may be detected. On the basis of this, the outflow of air from the

air outlets

30a, 30b associated with the passenger can be automatically controlled, for example by means of a motor-controlled control flap.

Alternatively or additionally, the outflow of air from the

air outlets

30a, 30b directed towards the passenger may be manually controlled, for example by a manually adjustable control tumbler.

Alternatively, a diffusion air outlet can also be provided in addition, for example in the region of the

air outlets

30a, 30b, through which the air flows indirectly to the passenger compartment.

Fig. 5 shows a second embodiment of an air conditioning system 10, in particular an air conditioner 12. The second embodiment corresponds substantially to the first embodiment. Therefore, only differences are explained below, and identical and functionally identical components are provided with the same reference numerals.

The air conditioning device 10, in particular the air conditioner 12, of the second embodiment differs from the air conditioning device of the first embodiment in that only one blower device 22 is provided and fresh air is sucked in the region of the air conditioner 12, in particular from the passenger compartment.

Here, the air supply channel 38 extends partially over the other components of the air conditioner 12 from the air intake region 43 to the blower device 22.

Of course, the air supply passage 38 may also extend partially under other components of the air conditioner 12.

The blower 22 is, for example, a radial blower with blower outlets offset by 180 °.

One

heat exchanger

24a, 24b is directly connected to each blower outlet.

The

heat exchangers

24a, 24b are in direct fluid connection with a first air discharge channel 26a and a second air discharge channel 26b, respectively.

The first air discharge channel 26a and the second air discharge channel 26b terminate in

air outlets

30a or 30b, respectively.

A plurality of

control flaps

44a and 44b and a respective shut-off

flap

46a and 46b are provided on the

air outlets

30a, 30b, respectively, for controlling the outflow of air.

The entire air conditioner 12 is supported in a longitudinal strut 48, which is, for example, part of the roof of the vehicle 1 and extends parallel to the longitudinal axis 20.

In the air intake region 43, a partition 50 is mounted on the longitudinal struts 48, by means of which the intake opening of the air supply channel 38 is covered, but nevertheless air can be taken in simultaneously.

The coolant supply line 32, the coolant return line 34 and the condensate line 36 extend through the longitudinal struts 48.

The features and characteristics of the respective embodiments can also be combined with each other in any manner.
