Description

Vehicle modular air conditioning system {MODULAR VEHICLE AIR CONDITIONING SYSTEM}

The present invention relates to a modular air conditioning system for a vehicle for operation in zones 1 to 4 when the temperature of the front and rear zones of the vehicle is set.

More and more multi-zone air conditioning systems are being used in vehicles due to higher expectations of comfort. These allow individual temperature settings and partial air distribution settings for all four seats of the vehicle, namely the front left and right seats and the rear left and right seats. Such multi-zone air conditioning systems are usually provided as optional equipment as a modification of a simple air conditioning system. For this reason, most of the modular air conditioning systems are presented, and these modular air conditioning systems can ideally implement variations of one to four climate zones within an installation space having the same interface. have. In this case, in most cases, a basic architecture is chosen that guarantees the existence of multiple zones by adding additional channels and internal dividing walls. At the same time, the expansion of the temperature zones takes place in a vertical direction, ie the front zones are fed from the upper area of the device and the rear temperature zones are fed from the lower area of the device. In this case, the vehicle air conditioning system is horizontally separated into upper and lower regions by a partition wall extending correspondingly horizontally in the region of the heat exchanger. The heat exchanger is thus divided into two zones, and air from these zones is guided to the upper air mixing chamber for the front zones and the lower air mixing chamber for the rear zones, respectively. Individual temperatures are set in the air mixing chambers for the respective zones by appropriately controlling the air flows, for example by means of control members in the form of a movable flap, a so-called temperature flap. In addition, the upper and lower air mixing chambers can be subdivided vertically, that is, transversely, to separate left and right, respectively, resulting in a total of four temperature zones.

DE 10 2004 033 402 A1 describes such a vehicle air conditioning system. In this case, the basic architecture of the 1st or 2nd zone of the air conditioning system is changed by adding horizontal dividing walls to the vertical expansion under the heated heat exchanger and the 3 or 4th zone variant of the air conditioning system. In other variants known in the prior art, various architectures are provided, in part for one or two zone variants, as well as for three or four zone variants.

A disadvantage of the prior art is on the one hand the variable or unused space for air flow due to different channel inserts. On the other hand, there is a significant drawback that the air channel for the total mass flow is smaller in the 1 or 2 zone variants than in the 3 direction 4 zone variants because there is an additional cold air channel under the heat exchanger. This situation adversely affects airflow and sound. However, the requirements for performance and acoustic conditions in the vehicle are not independent of the variant of the air conditioning system, but vary from vehicle to vehicle.

In addition, different control characteristics occur due to the different cross-sectional area ratios between the hot air and cold air paths, because the pressure loss ratio is different between the variants. In this case, further adjustment of the control strategy of the system is required to achieve uniform temperature control.

In the case of the formation of other variants, ie for the 1 or 2 zone and 3 and 4 zone variants, a separate housing version and thus a tool is required. In addition, these solutions increase the cost of development.

An object of the present invention is to develop a modular air conditioning system capable of avoiding the disadvantages of ventilation system performance and acoustics, particularly in the area around the heat exchanger. An additional objective is to integrate functions into the housing concept to reduce development and tool costs.

The above object of the present invention is solved by a modular air conditioning system for a vehicle having the features according to claim 1. Preferred refinements are presented in the dependent claims.

The modular air conditioning system for a vehicle according to the present invention is suitable for operating in 1 to 4 zones when the temperature of the front and rear zones of the vehicle is set. The vehicle modular air conditioning system includes at least one air conditioning system housing and a plurality of air temperature control and air distribution devices disposed within the housing. The mentioned group of air temperature control and air distribution devices includes one or more fans, evaporators, heat exchangers, one or more control members for controlling air flows through the heat exchanger and one or more control members for controlling air flows through the heat exchanger. It includes a control member. Further, as an air distribution device, air vents for the front regions of the vehicle and air vents for the rear regions of the vehicle are formed. Further, according to the present invention,-based on the lateral direction of the vehicle air conditioning system-an internal module centrally positioned within the air conditioning system housing is formed, and the internal module includes a vertically oriented separation wall. It has one or more parts. By the internal module, the vertically extending separation of the areas of the air conditioning system housing (from which air can be guided to the air vents of the rear areas of the vehicle) is adjacent to the air conditioning system housing. By means of zones (from which air can be guided air to the air vents of the front zones of the vehicle), the zones for the mentioned rear zones and front zones are in turn in the transverse direction (y). In this case, the areas for the rear areas are arranged in the center of the air conditioning system and the areas of the front areas are arranged on both sides of the outer side.

Preferably, all of the warm air control members for controlling air flows through the heat exchanger and all of the cold air control members for controlling air flows through the heat exchanger are each oriented in the transverse direction (y). In this case, according to one particularly preferred embodiment, all the hot air control members or all the cold air control members are each disposed on one shaft.

In this case, modularity is given in the air conditioning system housing with a uniform design for all variants of zones 1 and 2 and zones 3 or 4 by interchanging internal modules, and in the inner module the corresponding control member The arrangement of them appears. Thus, the inner module may include, for example, control members in the form of flaps as well as air guide members such as channels and/or deflectors for various functions. For the 3 and 4 zone variants, the inner module includes hot air control members and cold air control members for the rear zones. In such a system, air is guided in the direction of the rear vents in the rear or lower housing area, respectively. According to a preferred embodiment of the 3 or 4 zone variant, with respect to the transverse direction (y), the warm air control members for the front temperature zones are placed centrally on the same axis, on the side of the warm air control members for the rear zones. However, in this case, the warm air control members for the front zones and the warm air control members for the rear zones can preferably be controlled independently of each other. Correspondingly, with respect to the transverse direction y, the cold air control elements for the front temperature zones are arranged on the side of the cold air control elements for the rear zones, centered on the same axis. In this case, the cool air control members for the front zones and the cool air control members for the rear zones can likewise be controlled independently of each other.

In a 3 or 4 zone variant of the automotive modular air conditioning system, the centrally located internal module is located from the area following the heat exchanger, almost to the evaporator, based on the flow direction of the air, and thus between the evaporator and the heat exchanger. It reaches the area and can accommodate the warm air control members 18.1 and the cold air control members 18.2. According to one preferred embodiment, the inner module may comprise a system of hot and cold air control elements in the form of a temperature flap for the rear zone. The inner module directs air to the air vents in the rear zones at the rear or bottom of the vehicle air conditioning system. The temperature flaps for the front and rear zones are preferably arranged on the same axis, but the temperature flaps for the rear zones can be controlled independently independent of the temperature flaps of the front zones.

According to one preferred embodiment, the inner module is further configured such that the inner module closes the air paths for the air vents leading from the upper region to the front regions so that air can only pass from the inner module to the air vents for the rear regions. Is formed in a way. According to a preferred embodiment of the present invention, for this the inner module comprises two U-shaped shells as main parts, these shells are mounted on both sides of the vertical housing middle wall, in this case the vertical housing middle wall and The connection of the U-shaped shell is preferably a clip connection.

According to an improved example of the present invention, a bypass having a control member for opening and closing the bypass in the internal module for defrosting, that is, when air for defrosting on the windshield is required, can be provided, thereby The total air from the heat exchanger including the warm air from the internal module may be guided to the defrosting vent.

In the case of the 1 or 2 zone variant, the centrally positioned inner module has a modified dividing wall shape compared to the 3 or 4 zone variant. The internal module for the 1 or 2 zone variant includes air from the mixing chamber, i.e., the air from the region where the hot air air flow guided through the heat exchanger and the cold air air flow guided through the heat exchanger meet the air vents in the rear regions. It has a reduced dividing wall compared to the 3 or 4 zone variant to guide it. Therefore, the internal module is significantly reduced in the x-direction and is located in the area after the heat exchanger based on the flow direction of air. The internal module thus formed guides a portion of the air flowing from the cold and hot air control members from the mixing chamber to the direction of the air vents for the rear areas of the vehicle. The control elements for controlling the cold and hot air flows may be coupling control members corresponding to the three or four zone variants described above, for example a plurality of rotatable temperature flaps lying on one axis. However, the control members for controlling the cold and hot air flows may be individual control members having a correspondingly changed size, in particular length, in the y-direction in the 1 or 2 zone variant, by means of these control members the air vents of the front zones. As well as the flow of hot or cold air flowing to the air vents of the rear areas can be controlled. The control members may be multiple temperature flaps connected to each other while regulating the temperature for the front or rear zones. The control elements can also be individual temperature flaps, which each regulate the temperature of at least one front and at least one rear section or even cover the entire cross-sectional area of the vehicle air conditioning system. Due to the large cross section of the single zone or double zone variants, this design is superior to the prior art.

All variants of a modular air conditioning system for a vehicle in which the same cross-sectional area is always provided for cold and hot air flows are common. That is, the cross-sectional area of the hot air flow or the cold air flow in the air conditioning system housing is not changed by using the internal module in the air conditioning system. In this case, the centrally located inner module is only used in individual variants to guide the airflow to individual areas/zones of the vehicle's air conditioning system. In this case, the internal module guides the air in different ways to the various air vents of the vehicle air conditioning system. This avoids the reduced cross-sectional area, which is a disadvantage present in the prior art, in particular with respect to the 1 and 2 zone variants.

The advantages that can be achieved by the present invention can be summarized as follows:

The inventive concept of a vehicle modular air conditioning system with internal modules allows for the same cross-sectional area for cold and hot air flows inside the vehicle air conditioning system with respect to all the aforementioned variants. That is, a uniform installation space can be sufficiently used for all modifications of the vehicle air conditioning system. Since the cross-sectional area for cold and hot air flow is the same for all types, the influence on control characteristics, air flow or acoustics is also low. Tool and development costs are reduced because only certain parts of some variants are required.

In addition to the air conditioning system housing 1, the vehicle air conditioning system includes a number of air temperature control and air distribution devices not shown in FIG . 1 , such as, for example, fans, evaporators, heat exchangers and a number of control members.

The temperature zones for various areas of the vehicle are not disposed above and below the heat exchanger in the vertical direction, that is, in the z-direction, as in the prior art, but are disposed adjacent to each other in the transverse direction y.

With respect to the y-direction, the temperature zones of the rear zones are arranged in the center of the vehicle air conditioning system, and the temperature zones of the front zones are arranged outside the air conditioning system housing on both sides of the centrally arranged temperature ranges. This arrangement of temperature zones for different zones is achieved by the installation of an inner module 4 arranged in the center. The inner module 4 comprises two shell-shaped, substantially U-shaped parts 5.1, 5.2, which are, for example, the housing intermediate wall (visible in Fig. 1) lying in the xz plane by means of clips. Not). In this case each part 5. 1, 5.2 is oriented locally vertically, ie parallel to the xz plane, and thus each forms a vertical separation wall. 1 shows an internal module 4 provided in a four-zone variant of a vehicle air conditioning system. In this case each part 5.1, 5.2, starting from the lower edge, has a recess 6.1, 6.2 and optionally additional recesses, in which case a heat exchanger not shown in the drawing and in the case Accordingly, an additional electric heating element not shown in the drawing can be arranged at right angles to the vertical regions of the parts 5. 1, 5.2. In this way the inner module 4 reaches almost as far as the evaporator, more precisely the region between the evaporator and the heat exchanger. In addition, the inner module 4 can accommodate control elements such as temperature flaps, for example.

Figure 2a is a vehicle air cut in a transverse direction with respect to the y-direction looking from the outside and a vertical area of the shell-shaped portion 5.1 of the inner module 4 formed corresponding to the four-zone variant, serving as a dividing wall A cross-sectional view of the conditioning system 7 is shown. In this case the cross section shows air flow paths and control members for air flow to the first or second zone. Modular air conditioning systems for vehicles include air temperature control and air distribution devices. A fan (8) and flap-shaped control members (9.1, 9.2, 9.3, 9.4, 9.5) are provided as an air distribution device, and an evaporator (10), heat exchanger (11) and additional heating are provided as an air temperature control device. Elements 12 are provided. In addition, a filter member 13 for purifying air is provided between the fan 8 and the evaporator 10 as, for example, a pollen filter. The fan 8, the filter element 13, the evaporator 10, the heat exchanger 11 and the additional heating element 12 are arranged in sequence in the direction of air flow, and at the same time in the y-direction, i.e. the vehicle air conditioning system It is oriented parallel to the transverse direction of (7). As an additional air distribution device, a warm air flap 9.1 in front of the heat exchanger 11 and a cold air flap 9.2 on top of the heat exchanger 11 are provided to control the flows of cold and hot air. Further, Fig. 2a shows a defrosting vent 14 with different air vents or air vent channels and associated air vent flaps for the front zones, i.e. with a defrost flap 9.3, a corresponding dashboard flap ( It shows a legroom vent 17 with dashboard vents 15, 16 with 9.4, 9.5 and a legroom vent flap 9.6 for one of the front zones, i.e. the first and second zones.

Figure 2b is for a vehicle with air distribution devices for directing air to one of the air flow paths and the rear section of the vehicle at one location in the inner module 4, i.e. to the third or fourth zone in the case of the four zone variant shown A cross-sectional view of the modular air conditioning system 7 is shown. The inner module 4 almost reaches the evaporator 10 and, in addition to the region between the evaporator 10 and the heat exchanger 11, at the same time the temperature control members 18.1 and 18.2, in this case a warm air flap 18.1 as a temperature flap. And it is designed to accommodate air distribution devices in the form of a cold wind flap (18.2). The temperature flaps 18.1, 18.2 disposed in the inner module 4 can be controlled independently of the temperature flaps 9.1, 9.2 for the front zones, shown in Fig. 2a, and thus cold and hot air for the rear zones. It functions as a control member for controlling the flows. The shell shape of the portion 5. 1 of the inner module 4 is additionally closed by the air path to the air vents 14, 15, 16 leading from the upper area to the front zones, thereby allowing air from the inner module 4. Only allow access to air vents for rear areas. Accordingly, according to Fig. 2b , an air exhaust channel 19 is formed in the inner module 4, which directs air to one of the legroom vents and the rear zone, that is, the console vents in the third or fourth zone. do. The air outlet channel 19 has an air outlet flap 20 as a control member 20, the axis of rotation of the air outlet flap being the other flaps 9.1, 9.2, extending in the x-direction and in addition to the y-direction. 9.3, 9.4, 9.5, 9.6, 18.1, 18.2) are oriented perpendicular to their axis of rotation. Thus, in such a system, air can be guided in the direction of the rear zone vents in the rear or lower housing area. According to an embodiment not shown, in the case of defrosting in which air must be guided to the windshield, a control member may be additionally provided in the inner module 4 to guide the entire air from the heat exchanger to the defrosting vent. have. For example, a bypass flow path for guiding the hot air introduced into the internal module 4 from the internal module to the defrosting vent 14 may be provided, and a defrosting discharge flap as the control member is provided in the bypass flow path. The bypass flow path can be opened and closed.

Fig. 3a shows a perspective view of the area lying behind the evaporator of the modular air conditioning system 7 for a vehicle-with respect to the flow direction of the air-in this case the internal module designed for the 4 zone variant ( 4) is inserted. In other words, the evaporator is not shown in FIG. 3A , but a heat exchanger 11 is shown extending in the y-direction actually over the entire range of the vehicle air conditioning system 7. Each part (5.1, 5.2) of the inner module (4), the extension of the housing intermediate wall (21) in which the parts (5.1, 5.2) are fixed on both sides, respectively extend in the y-direction in the x-direction and the z-direction Greater than wealth. The parts 5. 1, 5.2 of the inner module 4 and the housing intermediate wall 21 are, as already mentioned on their lower surfaces, recesses 6. 1, 6.2, 22 corresponding to the height and thickness dimensions of the heat exchanger. Each has In this case, the recesses 6.1, 6.2, 22 are mutually arranged so that the heat exchanger 11 is disposed in the recesses 6.1, 6.2, 22, and thus the heat exchanger 11 is transverse as in FIG. 3A . It can be penetrated by the inner module 4 in the direction y. As a result, the inner module 4 is designed to extend almost up to the evaporator 10 and together with the region between the evaporator 10 and the heat exchanger 11, as shown in the corresponding cross-sectional views of FIGS . 2A and 2B . .

3B shows a front view of an arrangement of temperature flaps disposed between the evaporator and the heat exchanger as a control member of the vehicle modular air conditioning system for the four-zone variant. In this case, the temperature flaps 9.1 and 9.2 are a control member for controlling cold and hot air flows for the front zones, and relatively small as a control member for controlling cold and hot air flows for the rear zones arranged in the inner module. It is arranged on the side of the inner module 4 on the same axis 23.1, 23.2 as the sized temperature flaps 18.1, 18.2, but the temperature flaps can be controlled independently and mutually in the rear zones. In other words: two intermediate warm air flaps (18.1) for controlling the warm air for the rear zones are each on the same axis (23.1) as two externally adjacent warm air flaps (9.1) to control the warm air for the front regions. It is placed. Similarly, the two intermediate cold air flaps 18.2 for controlling the cold air for the rear regions are on the same axis 23.1 as the two externally adjacent cold air flaps 9.2, respectively, to control the cold air for the front regions. It is placed.

FIG. 4A shows a cross- sectional view of an in-vehicle air conditioning system 7 with an inner module for a two-zone variant positioned in the center, while FIG. 4B shows a cross-sectional view of the vehicle air-conditioning system 7 -Shown in the transverse direction to the axis. In this embodiment, a variant of the inner module 24 with a dividing wall structure of the parts 25.1 and 25.2, modified compared to the 3-zone or 4-zone variant, is provided. The internal module 24 for the two-zone variant has reduced separation walls compared to the internal module of the four-zone variant, so that the air flows from the mixing chamber 26 (see Fig. 4A), that is, the hot air flow guided through the heat exchanger. And the flow of cold air guided past the heat exchanger is guided to the air vents of the rear regions from the converging region. Therefore, the parts 25.1 and 25.2 of the internal module 24 are remarkably reduced in the x-direction, and are located in the area next to the heat exchanger 11 based on the flow direction of air, and thus cannot reach the evaporator 10. . In contrast to the inner module for the four-zone variant, the inner module 24 draws part of the air from the area of the temperature flaps 27.1, 27.2 (see Fig. 4A), i.e. from the mixing chamber 26 to the rear area of the vehicle. Guide them in the direction of the air vents.

4B shows the regions of the front zones starting from the mixing chamber and extending vertically by inserting an inner module 24 with parts 25.1, 25.2 mounted on either side of the housing intermediate wall 21 and from the mixing chamber. It shows the separation between the regions of the starting rear regions, that is to say, in this case the regions of the front and rear regions are arranged one after the other. Therefore, the areas for the legroom vents 28 in the front zones starting from the mixing chamber are arranged outside on both sides of the vehicle air conditioning system 7, and the zones for the legroom vents 29 in the rear zones continue to be inside and at the rear. The areas for the console vents 30 of the zones are centrally arranged on both sides of the housing intermediate wall 21.

The control elements for controlling the cold and hot air flows can in this case be a combined control element, such as a temperature flap of the three-zone or four-zone variant according to Fig. 3b, or a separate control element with a correspondingly varied size (length). 4C shows a front view of a temperature flap arrangement of a modular air conditioning system for a vehicle with internal modules for a two zone variant, positioned between the evaporator and the heat exchanger. In this case, the right and left warm air flaps 27.1, that is, temperature flaps located on both sides of the housing middle wall 21 after the heat exchanger in the air flow direction, are arranged on the first axis 31.1 extending in the y-direction. have. The right and left cold air flaps, i.e. the temperature flaps 27.2 located above the heat exchanger (not visible in Fig. 4c), have a second upper axis 31.2 extending parallel to the first axis 31.1 in the transverse direction y. ) Are placed adjacent to each other.

The control members 27.1 and 27.2, in this case as individual temperature flaps, regulate the temperature of the front and rear areas, respectively, and cover the cross-sectional areas of the left or right side of the vehicle air conditioning system, respectively, with the left and right sides of the vehicle air conditioning system. The separation extending vertically between the right side is achieved by means of the housing intermediate wall 21. Thus, the individual temperature flaps each cover the same cross-sectional area as the two temperature flaps 9.1; 18.1; 9.2; 18.2 of the four-zone variant according to Fig. 3b and are designed to be longer in the y-direction.
