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 to heat or cool, and to purify the air in the passenger compartment of the vehicle.

For this purpose, conventional air conditioning systems have an air conditioner which is usually arranged in the region of the vehicle cabin. The conditioned air may be discharged into the passenger cabin through an air outlet in the cockpit area. The air outlet may be manually or automatically adjustable to enable air to flow directly to a seated occupant.

Conventional air conditioning units, particularly conventional air conditioners, are relatively large and cumbersome and thus 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 smaller and smaller, it is becoming more and more difficult to integrate air conditioners in the cockpit area.

As the degree of (partial) automation of the vehicle increases, the seating position is also more variable, so that air must be able to flow to the seated and lying passengers. Sufficient air flow to the lying passenger cannot be achieved by conventional air conditioning arrangements, in which air flows to the passenger through an air outlet in the cabin area.

Disclosure of Invention

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

According to the invention, the object is achieved by an air conditioning device for conditioning the 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 the slim design and the extended size of the air conditioner, the air conditioner is designed compact, particularly in the lateral direction, so that the air conditioner has a size completely different from that of a conventional air conditioner. Thus, the air conditioner may be installed in other areas of the vehicle, such as a roof area, which have not been considered for the air conditioner 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 extend largely parallel, if appropriate taking into account the curvature of the longitudinal axis.

Alternatively, the longitudinal axis may have a curvature. In this way, the air conditioning system, in particular the air conditioner, can be adapted to the specific shape and structure of the vehicle component, such as the roof side.

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

Preferably, the individual components of the air conditioner are not disposed side by side laterally with respect to the longitudinal axis. For example, the component extends substantially parallel to the longitudinal axis. In this way, the air conditioner can be configured to be narrow in a transverse direction with respect to the longitudinal axis.

An embodiment provides that the at least one blower 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 blower device and the plurality of air outlets. The blower device serves as a blower device by which the heat exchanger is loaded with air and heats or cools the air. Therefore, the heat exchanger has an air heating or air cooling function. The heated or cooled air can flow out from the air outlet in a targeted manner into a specific region of the passenger compartment or into the passenger compartment of the vehicle in a diffuse manner. Thereby, air conditioning of the passenger compartment can be achieved.

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

In a further embodiment, two air outlet channels are provided, with one blower being in direct fluid connection with the two air outlet channels, or two blowers being provided, which are each in direct fluid connection with one air outlet channel. By having an arrangement with only one blower, the component costs and the production costs can be reduced. In an arrangement with two air blowing devices, smaller air blowing devices can be used and a 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 blower are arranged in sequence on the longitudinal axis. In this way, a narrow overall shape of the air conditioner can be ensured.

For example the blowing device is a radial blowing device. The radial blower may have outlets offset by 180 ° in this case, both of which lie on the longitudinal axis and are each connected to an air outlet channel.

According to one aspect, the air conditioner has an air supply channel which extends along a longitudinal axis and which is in fluid connection with one of the at least one blower device, in particular the air supply channel extends between two of the blower devices. By means of this air delivery channel, the intake of the desired air can be spatially separated from the air conditioner and thus noise emissions in the area of the air conditioner can be reduced.

It can be provided that the air outlet duct of the blower associated with the air outlet duct is at the same time the air supply duct of the other blower associated with the air supply duct. In this way, an additional air supply channel can be dispensed with and thus the number of components can be reduced.

In particular, the air delivery channel is arranged above or below one of the at least one air discharge channel. The air supply duct is thus not arranged laterally beside 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 elongated, said air outlet extending along the longitudinal axis. Thus, the height of the air outlet and thus the height 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. Thus, it is also possible to widen the area in the passenger compartment into which the air flow flows and ensure a comfortable air flow.

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

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, an air conditioner or air conditioning device may be coupled to the 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 offset with respect to the at least one heat exchanger transversely to the longitudinal axis or extends below the at least one heat exchanger. In this way, condensate formed in the heat exchanger can be conducted away from the air conditioner in a controlled manner, whereby uncontrolled accumulation of liquid in the air conditioner can be prevented.

Preferably, a misalignment is provided between the condensate outflow of a heat exchanger and the condensate line. By means of this offset, the condensate can be prevented from flowing back into another heat exchanger which is also in fluid connection with the condensate line.

Another embodiment provides that the air conditioning device has an air supply device with at least one supply blower and at least one air supply channel, the at least one supply blower being arranged below the longitudinal axis of the air conditioner, and the at least one air supply channel fluidly connecting the at least one supply blower with the air conditioner, in particular with the air supply channel. Accordingly, air required for air-conditioning the passenger compartment can be delivered to the air conditioner from a region spatially separated from the passenger compartment.

According to a further embodiment, the air conditioning device has a temperature control assembly separate from the air conditioner for controlling the temperature of the coolant, 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 regulating assembly is disposed below the longitudinal axis and/or spatially separated from the air conditioner. Thus, the temperature adjustment of the coolant required for adjusting the air in the air conditioner takes place in a region remote from the air conditioner, in particular remote from the passenger cabin, so that noise emissions and heat emissions in the air conditioner region, in particular in the passenger cabin region, can be reduced.

Furthermore, according to the invention, the object is achieved by a vehicle comprising a roof bounding 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 from the roof region into the passenger compartment and in this case also a direct flow of air to the lying passengers is possible, a reliable flow of air to the passengers in the passenger compartment is ensured. In addition, due to the elongate extension of the air conditioner, free areas can be provided transverse to the longitudinal axis of the air conditioner, which free areas 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, uniform air conditioning of the vehicle can be achieved by the air conditioning device.

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

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

Preferably, the longitudinal struts extend in the longitudinal direction of the air conditioner. In this way, the air conditioner may be fully received in the longitudinal struts.

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

In particular, columns A, B, C and/or D provide condensate extraction channels. By utilizing the interior space of the a, B, C and/or D columns, installation space and material for additional separate condensate extraction channels can be saved.

It may be provided that the condensate line, the coolant supply line, the coolant return line and/or the air supply channel of the air conditioner extend through the condensate outlet channel. Thus, the space in the condensate extraction passage can be optimally utilized.

In another embodiment, the air supply device is disposed in the vehicle tail or in the vehicle head, and/or the temperature regulating assembly is disposed in the vehicle tail or in the vehicle head. Thus, acoustic emissions and thermal emissions emitted from the air supply and/or the temperature regulating assembly may be kept away from the passenger compartment.

In particular, the a, B, C and/or D columns provide air supply passages that fluidly connect the air supply device with the air conditioner. Accordingly, air required for air-conditioning the passenger compartment can be delivered to the air conditioner from a region spatially separated from the passenger compartment. In addition, by using the inner space of the a-pillar, the B-pillar, the C-pillar, and/or the D-pillar as the air supply passage, installation space and materials for additional separate air supply passages can be saved.

Another embodiment provides that the vehicle has at least one wheel housing in which a supply blower is arranged and/or is designed to suck air from the wheel housing. The air intake is thereby carried out in a region remote from the air conditioner, in particular remote from the passenger cabin, so that noise emissions in the region of the air conditioner, in particular in the region of the passenger cabin, 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. Thus, a full air conditioning of the passenger compartment can be achieved, whereby comfort in the vehicle can be greatly improved.

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

Detailed Description

In fig. 1 a vehicle 1 is shown, which has an a-pillar 3, a B-pillar 5, a C-pillar 7 and a D-pillar 8, and a roof 9. The roof 9 delimits the passenger compartment of the vehicle 1.

An air conditioning device 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 arranged on the 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 without the D-pillar 8 is shown in fig. 2.

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

The air supply 14 is arranged below the longitudinal axis 20 and in this embodiment is placed 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 14 and the temperature regulating assembly 16 may also be disposed in other areas of the vehicle 1 below the longitudinal axis 20.

The air conditioner 12 is fluidly connected to the air supply 14 and the temperature regulation assembly 16 by at least a portion of a supply passage 18. For example, the supply channels 18 comprise 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 channel 18 may also be provided in other components, such as in the B-pillar 5 and the D-pillar 8.

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

Optionally, the air conditioner 12 is coupled with a position sensor device 21 by means of 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 device 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, one heat exchanger 24, two air discharge passages 26a, 26b, one air delivery passage 28, and four air outlets 30a, 30b.

The air discharge passages 26a, 26b terminate in respective air outlets 30a, 30b.

The blower devices 22a, 22b are radial blower devices, for example.

The first blower device 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 blower means are connected in between.

The heat exchanger 24 is directly connected to the first blower device 22a, the first air discharge passage 26a, and the air delivery passage 28. Here, it is provided that 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 is also possible to provide that the first air outlet duct 26a simultaneously forms the air supply duct 28.

A second blower device 22b is connected in a flow-through manner between the air supply duct 28 and the second air outlet duct 26 b. The second air blowing device 22b is directly in fluid connection with the second air discharge passage 26b and the second air outlet 30b.

The second air discharge channel 26b is directly connected to the second blower 22b and is split in a scissor-like manner towards its ends, which second air discharge channel ends in a second air outlet 30b.

Such a scissors-type separation structure may also be provided in the first air outlet passage 26 a.

Optionally, 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 extension of the air outlets 30a, 30b, in particular of the openings of the air outlets 30a, 30b, is greater than the transverse extension thereof or of the openings of the air outlets 30a, 30b. For example, the ratio of the longitudinal extension to the transverse extension is 5:1.

the various components of the air conditioner 12 described above are disposed 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 disposed partially over 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, coolant return line and condensate line may be part of the supply channel 18.

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

The condensate line 36 is divided in the region of the a-column 3 and the C-column 7 into two sub-lines 36a, 36b, respectively, which sub-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 sub-lines 36a, 36B in the region of the other components, for example in the region of the B-column 5 and the D-column 8, respectively, which sub-lines 36a, 36B then extend through the B-column 5 and the D-column 8, respectively.

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

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

The air supply 14 essentially comprises an external supply blower 40 and an intake manifold 42, which is in fluid connection with 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 may be provided that the C-pillar 7 forms the 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.

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

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

The air is then directed through a heat exchanger 24 where it is heated or cooled as desired. To this end, a coolant supply line 32 conveys hot or cold coolant from the temperature regulation assembly 16 to the heat exchanger 24, and a coolant return line 34 conveys cold or hot coolant from the heat exchanger 24 back into the temperature regulation assembly 16. Thereby forming a coolant circuit through which conditioning of the air flowing through the heat exchanger 24 can be effected.

Condensate formed in the heat exchanger 24 is controllably drawn off via 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 conveying 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 one unit which is assigned to each row of seats in the vehicle and supplies conditioned air to the row of seats.

To ensure an optimal direct flow of air to the occupant in any seating position, the air conditioner 12 may be coupled with a position sensor device 21 (see fig. 2) by which the presence of the occupant and/or seating position may be detected. On the basis of this, the outflow of air from the air outlet 30a, 30b associated with the passenger can be controlled automatically, for example by means of a motor-controlled control flap.

Alternatively or additionally, the outflow of air from the air outlets 30a, 30b oriented towards the passenger may be controlled manually, for example by a manually adjustable control flip.

Alternatively, a diffusion air outlet may 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 device 10, in particular an air conditioner 12. The second embodiment substantially corresponds to the first embodiment. Therefore, only differences will be described below, and the same and functionally identical components are provided with the same reference numerals.

The air conditioning system 10, in particular the air conditioner 12, of the second embodiment differs from the air conditioning system 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.

The air supply duct 38 extends here from the air intake area 43 to the blower device 22 partially above the other components of the air conditioner 12.

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 having blower outlets offset by 180 °.

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

The heat exchangers 24a, 24b are directly fluidly connected to the first air discharge passage 26a and the second air discharge passage 26b, respectively.

The first air discharge passage 26a and the second air discharge passage 26b terminate at an air outlet 30a or 30b, respectively.

A plurality of control flaps 44a and 44b, each for controlling the outflow of air, and a shut-off flap 46a and 46b are provided on the air outlet 30a, 30b.

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 strut 48, which covers the air intake opening of the air supply duct 38, but nevertheless allows air to be sucked in at the same time.

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 one another in any manner.
