[0003] Air conditioning systems with heat exchangers are commonly used in automotive climate system applications. Air conditioning systems provide climate comfort to the driver and passengers in the vehicle's passenger compartment, enhancing their ride experience and comfort. Today's modern systems offer many different climate options, and when the system produces heated air for the passenger compartment, it must discharge cooled air into the surrounding environment. Conversely, when the system produces cooled air for the passenger compartment, it must discharge heated air into the surrounding environment. To accommodate these various climate options and the ability to discharge air into the surrounding environment, air conditioning systems are complex in design and involve numerous components, such as heat exchangers, refrigerant circuits with varying compositions, fan units, filters, and door units. Door units control the various air flows within the system, and numerous door units are required to implement various system functions. Door units are typically integrated into the system structure as conventional baffles and are controlled by a control unit or module that is part of the vehicle's climate system. Consequently, due to the large number of components involved and the need to discharge air into the surrounding environment, the overall volume required to house the air conditioning system in the vehicle is relatively large.

[0004] Therefore, there is a need for an improved door unit configuration, air conditioning system arrangement, and method for operating an air conditioning system. Summary of the Invention

In the first operating position, the baffle member allows the first air flow and the second air flow to flow into the third air flow channel. The first operating mode allows a mixture of the first air flow and the second air flow to enter the passenger compartment.

Air is conveyed from the surrounding environment E to the first and second air flow channels 3a, 3b and may pass through one or more air filters or similar components before entering the respective first and second air flow channels. The one or more air filters may be located, for example, in the engine compartment of the vehicle. Air from the surrounding environment is conveyed to the first and second air flow channels 3a, 3b by one or more fan units, thereby forming the first and second air flows F1, F2 within the housing structure 2.

[0038] like Figures 1a to 1c as well as Figures 2a to 2c As shown, the first heat exchanger 4a is arranged in the first air flow channel 3a, and the second heat exchanger 4b is arranged in the second air flow channel 3b. The heat exchanger can be of any type and structure suitable for vehicle application. In the embodiment shown, the first heat exchanger 4a is suitable for cooling the first air flow F1, and the second heat exchanger 4b is suitable for heating the second air flow F2. For example, Figures 1a to 1c as well as Figures 2a to 2c As further shown, extensions of the first and second airflow channels 3a, 3b form a third airflow channel 6. A door unit 5 is disposed within the housing structure 2 and is configured to distribute a first airflow F1 within the first airflow channel 3a and a second airflow F2 within the second airflow channel 3b, as will be described further below. The third airflow channel 6 is configured to distribute the first and / or second airflow F2 to the passenger compartment C. The system also includes a fourth airflow channel 7. The fourth airflow channel 7 is configured to distribute the first and second airflow F1, F2 to the surrounding environment E. When the first and second airflow F1, F2 enter the fourth airflow channel 7, a fourth airflow F4 is formed within the fourth airflow channel 7. Suitable air channels, air hoses or similar components can be connected to the shell structure 2 for guiding air from the surrounding environment E into the first air flow channel and the second air flow channel, from the third air flow channel 6 for further transporting air from the shell structure 2 to the passenger compartment C, and from the fourth air flow channel 7 for further transporting air from the shell structure 2 to the surrounding environment E.

[0039] like Figures 1a to 1c As shown schematically, if necessary, air can be circulated from the passenger compartment C to the first air flow channel 3a. Figures 1a to 1cIn the illustrated embodiment, a recirculation duct 19 is arranged between the passenger compartment C and the first airflow passage 3a to distribute the recirculated air. The fifth airflow F5 is recirculated from the passenger compartment C to the first airflow passage 3a in the recirculation duct 19, where it mixes with the first airflow F1.

[0040] The air conditioning system 1 further comprises a door unit 5, such as Figures 1a to 1c 、 Figures 2a to 2c 、 Figures 3a to 3c 、 Figures 4a to 4c 、 Figures 5a to 5e 、 Figures 6a to 6d ,as well as Figure 7 The system 1 is schematically shown. The system 1 is arranged to operate in different system operating modes for distributing the first air flow F1 and the second air flow F2, which will be further explained below. The door unit 5 is configured to guide the first air flow F1 and the second air flow F2 to the passenger compartment C via the third air flow channel 6, for example Figure 1a and Figure 2a The door unit 5 is further configured to guide the first air flow F1 and the second air flow F2 to the passenger compartment C via the third air flow channel 6 and to the surrounding environment E via the fourth air flow channel 7, for example Figure 1b to Figure 1c and 2b to Figure 2c Therefore, the door unit 5 is configured to guide the first air flow F1 in the first air flow channel 3a and the second air flow F2 in the second air flow channel 3b to the third air flow channel 6, or to guide them to the third air flow channel 6 and the fourth air flow channel 7.

[0041] The door unit 5 comprises a fixed inner screen portion 5a, an outer shell portion 5b, and a baffle member 5c. Figures 1a to 1c 、 Figures 2a to 2c 、 Figures 3a to 3c 、 Figures 4a to 4c 、 Figures 5a to 5e 、 Figures 6a to 6d ,as well as Figure 7As shown schematically. The inner screen portion 5a of the door unit 5 is fixedly arranged relative to the shell structure 2. The outer shell portion 5b has a hollow structure surrounding the inner screen portion 5a, and in different system operating modes, the outer shell portion 5b is rotatably arranged relative to the inner screen portion 5a between different operating positions. In the embodiment shown, the inner screen portion 5a is arranged inside the outer shell portion 5b. The baffle member 5c is attached to the outer shell portion 5b, and the baffle member is arranged to distribute the first air flow F1 and the second air flow F2 into the passenger compartment C according to the system operating mode of the air-conditioning system 1. The baffle member 5c is also configured to block the first air flow channel 3a or the second air flow channel 3b according to the system operating mode. Due to the fixed arrangement of the inner screen portion 5a relative to the shell structure 2, the outer shell portion 5b of the door unit 5 is rotatably arranged relative to both the inner screen portion 5a and the shell structure 2 between different operating positions.

[0042] For example, Figure 5b As shown, the inner volume 8 of the door unit 5, which is enclosed by the inner screen portion 5a and the outer shell portion 5b, forms the fourth airflow channel 7. With this configuration, the door unit 5 is arranged to guide the first airflow F1 or the second airflow F2 into the inner volume 8 forming the fourth airflow channel 7, depending on the system operating mode. The outer shell portion 5b includes a first inlet opening 9a and a second inlet opening 9b. The respective inlet openings are arranged to guide the first airflow F1 in the first airflow channel 3a or the second airflow F2 in the second airflow channel 3b into the fourth airflow channel 7, depending on the system operating mode. Therefore, the outer shell portion 5b of the door unit 5 is configured to guide the first airflow F1 to the fourth airflow channel 7 via the first inlet opening 9a, and to guide the second airflow F2 to the fourth airflow channel 7 via the second inlet opening 9b.

[0043] As described above, the outer shell portion 5b is rotatably arranged relative to the inner screen portion 5a, and the outer shell portion 5b is configured to rotate about the inner screen portion 5a along the rotation axis direction D. RA Extended rotation axis A R Rotation, for example Figure 5a to Figure 5b ,as well as Figure 5d The housing portion 5b may be connected to an electric motor or other suitable actuating device, for example, to rotate the housing portion 5b relative to the inner screen portion 5a between different positions. The housing portion 5b includes a side wall 11a, an open base 11b, and a top wall 11c, for example, as shown in FIG. Figure 5b The side wall 11a has a RA The upper elongated structure, and the side wall 11a around the rotation axis A RThe open base 11b forms an outflow port 7a of the fourth air flow channel 7 to the surrounding environment E. The housing structure 2 is provided with an outflow port opening 2a connected to the inner screen portion 5a. The outflow port opening 2a corresponds to the outflow port 7a formed by the open base 11b and is used to further distribute the fourth air flow F4 in the fourth air flow channel 7 to the surrounding environment E. The first inlet opening 9a and the second inlet opening 9b are arranged in the side wall 11a. In the embodiment shown, the first inlet opening 9a and the second inlet opening 9b have an inflow port in the direction of the rotation axis D. RA Extending on or substantially in the direction of the rotation axis D RA In the embodiment shown, the first inlet opening 9a and the second inlet opening 9b have an elongated rectangular shape. However, it should be understood that in alternative embodiments, the first inlet opening 9a and the second inlet opening 9b may have any suitable configuration or shape, such as, for example, a circle, an oval, or any other regular or irregular shape.

[0044] In the embodiment shown in the figures, the outer shell portion 5b has a frustoconical configuration, while the inner screen portion 5a has a partially frustoconical shape corresponding to the shape of the outer shell portion 5a, for efficient operation of the door unit 5. Thus, depending on the rotational position of the outer shell portion 5b relative to the inner screen portion 5a, the inner screen portion 5a has a shape that either blocks airflow into the first and second inlet openings 9b, 9b, or allows airflow into the first or second inlet openings 9b, 9b. The sections of the inner screen portion 5a that block the first and second inlet openings 9a, 9b of the outer shell portion 5b in different operating positions should ensure a tight connection between these parts to prevent any airflow from entering the blocked inlet openings. Therefore, the inner screen portion 5a can have a shape corresponding to that of the outer shell portion 5b, wherein these parts tightly fit together when connected to form a blocking function. In other embodiments, the outer shell portion 5b and the inner screen portion 5a can have any suitable configuration and shape, depending on the design of the air conditioning system 1. As an example, the outer shell portion 5b can alternatively have a cylindrical configuration. The inner screen portion 5a may have any suitable shape as long as the function of blocking and unblocking the inlet opening is achieved.

[0045] The baffle member 5c is attached to the side wall 11a of the housing portion 5b. The baffle member 5c may be arranged as an integrated structural part of the housing portion 5b, or alternatively may be arranged as a separate structural part attached to the housing portion 5b by a suitable attachment mechanism. The housing portion 5b may also include one or more guide blades 12, wherein the one or more guide blades 12 intersect the baffle member 5c. For example, in Figures 2a to 2c 、 Figure 5a to Figure 5b as well as Figure 5d to Figure 5eIn the illustrated embodiment, the housing portion 5b includes two guide vanes. However, any suitable number of guide vanes 12 may be used. If desired, the guide vanes 12 may be omitted. The guide vanes 12 are arranged to guide and distribute the first air flow F1 from the first air flow channel 3a and the second air flow F2 from the second air flow channel into the third air flow channel 6.

Figure 6d In the embodiment, the baffle member 5c has a curved non-planar configuration with a curvature in the rotation axis direction D. RA The non-planar structure is suitable for controlling the flow of air into the third air flow channel 6 in the direction of the rotation axis D. RA The air flow distribution between the first air flow F1 and the second air flow F2 is described in detail below.

[0047] like Figure 5a As shown schematically, the two guide vanes 12 cooperate with the two horizontal partition members 6a arranged in the third air flow channel 6 to effectively distribute the first air flow F1 and / or the second air flow F2 into the third air flow channel 6. Figure 5a As shown, the horizontal partition member 6a is configured as a flat air guide member connected to and extending between the side walls 2b of the housing structure 2. A shaped vertical partition member 6b is arranged between the horizontal partition members 6a to effectively distribute the third air flow F3 in the third airflow channel 6. The vertical partition member 6b may, for example, have a shape corresponding to that of the baffle member 5c. However, in alternative embodiments, the horizontal partition member 6a and the vertical partition member 6b may have any suitable shape or configuration. The system may be provided with any suitable number of horizontal partition members 6a and vertical partition members 6b.

[0048] By means of the arrangement with two guide vanes 12 and two cooperating partition members 6a, the third air flow F3 in the third air flow channel 6 can be divided into three split air flows for further distribution to different parts of the passenger compartment C. Figure 5a In the orientation of the system 1 in FIG, the third air flow F3 can be divided into three different split air flows. The upper first split air flow F31 can be further distributed to, for example, the upper region of the passenger compartment C, such as the windshield and side windows. The middle second split air flow F32 can be distributed toward, for example, the occupants of the passenger compartment C. The lower third split air flow F33 can be distributed toward, for example, the lower region of the passenger compartment C (such as the floor area).

[0049] If a baffle member 5c having a flat configuration is used, it has a flat surface in the direction D relative to the rotation axis. RA With baffle angle α F The extension in the plane of arrangement, such as Figure 6b As shown, or having a non-planar configuration, such as Figures 6c to 6d As shown, the third air flow F3 may have different temperatures in different areas of the third air flow channel 6. Figure 5a As shown in the illustrated embodiment, due to the shaped configuration of the baffle member 5c, the upper first cut air flow F31 can receive more warm air from the second air flow F2 than the cool air received from the first air flow F1. Due to the shaped configuration of the baffle member 5c, the middle second cut air flow F32 can receive more cool air from the first air flow F1 than the warm air received from the second air flow F2. Due to the shaped configuration of the baffle member 5c, the lower third cut air flow F33 can receive more warm air from the second air flow F2 than the cool air received from the first air flow F1. This configuration of air flows allows the driver and passengers in the passenger compartment C to be distributed with a cooler air mixture than the air mixture distributed to the lower and upper areas of the passenger compartment C, achieving optimal climate comfort.

[0050] The inner panel portion 5a includes a RA The screen wall 10 has an extended structure, for example Figure 5c The inner screen portion 5a partially surrounds the rotation axis A. R The inner screen portion 5a extends and at least partially surrounds the outflow opening 2a of the housing structure 2. Depending on the system operating mode, the inner screen portion 5a blocks one or both of the first inlet opening 9a and the second inlet opening 9b of the outer shell portion 5b. The inner screen portion can be provided as an integral part of the housing structure 2 extending into the outer shell portion 5b, or alternatively can be attached to the housing structure 2 using a suitable attachment mechanism.

[0051] The different components of the door unit 5 may be made from any suitable material, such as for example a suitable plastic material, metal, a composite material or a combination of different materials.

[0052] The system 1 further comprises at least one fan unit for forming a first air flow F1 in the first air flow channel 3a and a second air flow F2 in the second air flow channel 3b. Figures 1a to 1c In the illustrated embodiment, the system includes a fan unit arranged in each of the first airflow channel 3a and the second airflow channel 3b, i.e., two fan units. A first fan unit 16a is arranged in the first airflow channel 3a to form a first airflow F1, and a second fan unit 16b is arranged in the second airflow channel 3b to form a second airflow F2. The respective fan units can be operated independently to control the first airflow F1 and the second airflow F2, respectively. By independently operating the fan units, the air speeds of the first airflow F1 and the second airflow F2 can be varied for optimal operation of the air conditioning system 1. The different air speeds of the first fan unit 16a and the second fan unit 16b can change the distribution of the cool air from the first airflow F1 in the first airflow channel 3a and the hot air from the second airflow F2 in the second airflow channel 3b, thereby properly mixing the cool and hot air flowing into the passenger compartment C. It should be understood that the first air flow F1 from the first air flow channel 3a and the second air flow F2 from the second air flow channel 3b may exhibit differences depending on the air flow speed from the first fan unit 16a and the second fan unit 16b. The air speed may also affect the temperature mixing of the first air flow F1 and the second air flow F2 entering the third air flow channel 6.

[0053] exist Figures 1a to 1c In the illustrated embodiment, a first air filter 22a is disposed in the first air flow passage 3a upstream of the first heat exchanger 4a, and a second air filter 22b is disposed in the second air flow passage 3b upstream of the second heat exchanger 4b. A third air filter 22c is disposed in the third air flow passage 6 downstream of the door unit 5. In alternative embodiments, the air filters may be disposed elsewhere in the air conditioning system.

[0054] The system 1 further comprises a refrigerant circuit 13 for cooling the first air flow F1 and for heating the second air flow F2, such as Figures 1a to 1c As shown. The first heat exchanger 4a and the second heat exchanger 4b are integrated into the refrigerant circuit 13, and the first heat exchanger 4a is configured as an air evaporator in the refrigerant circuit 13, while the second heat exchanger 4b is configured as an air condenser in the refrigerant circuit 13. The refrigerant circuit 13 also includes a compressor 14 and an expansion valve 15. The refrigerant circuit 13 can have a conventional structure with a suitable refrigerant for vehicle applications, wherein different components are connected to each other by suitable pipes. Figures 1a to 1c The refrigerant circuit 13 shown schematically only illustrates the main components of the system.

[0055] The refrigerant circuit 13 may also include other components for the efficient operation of the air conditioning system 1, such as, for example, one or more control valves, an accumulator tank, a muffler, sensors, connectors, and additional heat exchangers. Figure 8 An alternative embodiment of the refrigerant circuit 13 is schematically shown in FIG. In this alternative embodiment, the refrigerant circuit further comprises a water-cooled condenser 20 arranged upstream of the second heat exchanger 4b, and a refrigerator 21 arranged downstream of the second heat exchanger 4b and connected in parallel with the first heat exchanger 4a. Figure 8 As shown, the system includes two expansion valves 15 arranged upstream of the first heat exchanger 4a and the refrigerator 21, respectively. In this embodiment, the first heat exchanger 4a is configured as an evaporator, while the second heat exchanger 4b is configured as a condenser. The heat exchangers are arranged in the housing structure 2 in the same manner as in the above embodiment.

[0056] The system is designed to operate in three different system operation modes. Figure 1a 、 Figure 2a 、 Figure 3a and Figure 4a The first system operation mode M1 is shown in FIG. Figure 1b 、 Figure 2b 、 Figure 3b and Figure 4b The second system operation mode M2 ​​is shown in FIG. Figure 1c 、 Figure 2c 、 Figure 3c and Figure 4c In the different system operation modes, the outer shell part 5b of the door unit 5 is rotated relative to the inner screen part 5a and the housing structure 2 around the rotation axis A. R In the first system operation mode M1, the outer shell part 5b is arranged in the first operation position P1 relative to the inner screen part 5a and the housing structure 2, as shown in FIG. Figure 1a 、 Figure 2a 、 Figure 3a and Figure 4a In the second system operation mode M2, the outer shell portion 5b is arranged in the second operation position P2 relative to the inner screen portion 5a and the housing structure 2, as shown. Figure 1b 、 Figure 2b 、 Figure 3b and Figure 4b In the third system operation mode M3, the outer shell portion 5b is arranged in a third operation position P3 relative to the inner screen portion 5a and the housing structure 2, as shown. Figure 1c 、 Figure 2c 、 Figure 3c and Figure 4cshown.

[0057] In the first system operation mode M1, the outer shell part 5b is arranged in the first operation position P1 relative to the inner screen part 5a, as shown in FIG. Figure 1a 、 Figure 2a 、 Figure 3a and Figure 4a As shown. In the first operating position P1, the inner screen portion 5a blocks the first and second inlet openings 9a and 9b, preventing the first and second air flows F1 and F2 from flowing into the fourth airflow channel 7. In the first operating position P1, the baffle member 5c does not block the first or second airflow channels 3a and 3b, allowing both the first and second airflows F1 and F2 to flow into the third airflow channel 6. Therefore, in the first system operating mode M1, the first and second airflows F1 and F2 are directed only into the third airflow channel 6 leading to the passenger compartment C. In this system operating mode, the first and second inlet openings 9a and 9b of the outer shell portion are blocked by the inner screen portion, so no air can enter the fourth airflow channel 7 formed by the interior volume 8 of the door unit 5 and enclosed by the inner screen portion 5a and outer shell portion 5b. In the first system operating mode M1, the first and second airflows F1 and F2 are combined to form the third airflow F3, and the air velocities of the first and second airflows F1 and F2 can be adjusted according to the desired climate in the passenger compartment C. Therefore, in the first system operating mode M1 , no air is distributed to the surroundings E via the fourth air flow channel 7 .

[0058] In the second system operation mode M2, the outer shell portion 5b is arranged in the second operation position P2 relative to the inner screen portion 5a, as shown in FIG. Figure 1b 、 Figure 2b 、 Figure 3b and Figure 4bAs shown. In the second operating position P2, the inner screen portion 5a blocks the second inlet opening 9b and prevents the second air flow F2 from flowing into the fourth air flow channel 7. Through the rotational position of the outer shell portion 5b relative to the inner screen portion 5a, the inner screen portion 5a no longer blocks the first inlet 9a and allows the first air flow F1 to flow into the fourth air flow channel 7. In the second operating position P2, the baffle member 5c blocks the first air flow channel 3a and thus prevents the first air flow F1 from flowing into the third air flow channel 6. The blocking of the first air flow channel 3a by the baffle member 5c effectively prevents the first air flow F1 in the first air flow channel 3a from flowing into the third air flow channel 6, but since the first inlet opening 9a is no longer blocked by the inner screen portion 5a, the first air flow F1 is instead directed into the fourth air flow channel 7. In the second operating position P2, the baffle member 5c allows the second air flow F2 to flow into the third air flow channel 6. In the second system operating mode M2, the second air flow F2 from the second air flow channel 3b forms a third air flow F3 in the third air flow channel 6 leading to the passenger compartment C, and the first air flow F1 from the first air flow channel 3a forms a fourth air flow F4 in the fourth air flow channel 7 leading to the surrounding environment E.

[0059] In the third system operation mode M3, the outer shell part 5b is arranged in a third operation position P3 relative to the inner screen part 5a, as shown in FIG. Figure 1c 、 Figure 2c 、 Figure 3c and Figure 4c As shown. In the third operating position P3, the inner screen portion 5a blocks the first inlet opening 9a and prevents the first air flow F1 from flowing into the fourth air flow channel 7. Due to the rotational position of the outer shell portion 5b relative to the inner screen portion 5a, the inner screen portion 5a no longer blocks the second inlet opening 9b and allows the second air flow F2 to flow into the fourth air flow channel 7. In the third operating position P3, the baffle member 5c blocks the second air flow channel 3b and thus prevents the second air flow F2 from flowing into the third air flow channel 6. The blocking of the second air flow channel 3b by the baffle member 5c effectively prevents the second air flow F2 in the second air flow channel 3b from flowing into the third air flow channel 6, but since the second inlet opening 9b is no longer blocked by the inner screen portion 5a, the second air flow F2 is instead directed into the fourth air flow channel 7. In the third operating position P3, the baffle member 5c allows the first air flow F1 to flow into the third air flow channel 6. In the third system operating mode M3, the first air flow F1 from the first air flow channel 3a forms a third air flow F3 in the third air flow channel 6 leading to the passenger compartment C, and the second air flow F2 from the second air flow channel 3b forms a fourth air flow F4 in the fourth air flow channel 7 leading to the surrounding environment E.

[0060] The system may also include a control unit 17, wherein the control unit 17 is configured to control various components of the air conditioning system 1, such as, for example, the air flow rate through the fan unit, the air temperature from the heat exchanger, and the door unit position, as well as the operation of the system 1 in the various system operating modes described. The control unit 17 is connected to the air conditioning system and may form part of other vehicle control systems. The control unit may include appropriate software and one or more processors, as well as hardware components for controlling the air conditioning system 1. The control unit 17 may also be connected to one or more suitable sensors arranged in the passenger compartment C or elsewhere in the vehicle to detect ambient and other conditions, such as, for example, temperature, air humidity, exposure to sunlight, movement in the passenger compartment, fan speed, and air flow rate.

[0061] When operating the air conditioning system 1, the control unit 17 collects information from various sensors and, based on detected environmental conditions, controls the first and second air flows F1, F2 by setting the outer shell portion 5b and the baffle member 5c to different operating positions. If, based on the detected environmental conditions, a mixed flow of cool and hot air should be distributed into the passenger compartment C, the system is configured in the first system operating mode M1. In the first system operating mode M1, the outer shell portion 5b is rotated relative to the inner screen portion 5a to its first operating position P1. In this first operating position P1, the inner screen portion 5a blocks the first and second inlet openings 9a, 9b, preventing the first and second air flows F1, F2 from flowing into the fourth air flow passage 7. In the first operating position P1, the baffle member 5c allows the first and second air flows F1, F2 to flow into the third air flow passage 6 leading to the passenger compartment C. If, based on the detected environmental conditions, a flow of hot air should be distributed into the passenger compartment C, the system is configured in the second system operating mode M2. In the second system operating mode M2, the outer shell portion 5b is rotated relative to the inner screen portion 5a to a second operating position P2. In the second operating position P2, the inner screen portion 5a blocks the second inlet opening 9b, preventing the second air flow F2 from flowing into the fourth air flow channel 7 and allowing the first air flow F1 to flow into the fourth air flow channel 7. In the second operating position P2, the baffle member 5c blocks the first air flow channel 3a, preventing the first air flow F1 from flowing into the third air flow channel 6 and allowing the second air flow F2 to flow into the third air flow channel 6. If, based on detected environmental conditions, the cool air flow should be distributed into the passenger compartment C, the system is configured in the third system operating mode M3. In the third system operating mode M3, the outer shell portion 5b is rotated relative to the inner screen portion 5a to a third operating position P3. In the third operating position P3, the inner screen portion 5a blocks the first inlet opening 9a, preventing the first air flow F1 from flowing into the fourth air flow channel 7 and allowing the second air flow F2 to flow into the fourth air flow channel 7. In the third operating position P3 , the baffle member 5 c blocks the second airflow passage 3 b , prevents the second airflow F2 from flowing into the third airflow passage 6 , and allows the first airflow F1 to flow into the third airflow passage 6 .

[0062] exist Figure 7, schematically illustrates an alternative embodiment of an air conditioning system 1. In this embodiment, the system further includes two additional air control dampers: a first air control damper 18a is positioned in the first air flow channel 3a, and a second air control damper 18b is positioned between the first and second air flow channels 3a, 3b. The dampers can be used to direct the cool air flow after the first heat exchanger 4a in the first air flow channel 3a to the second air flow channel 3b before the second heat exchanger 4b. This arrangement is useful if air drying is required before heating. During cooling, the air is dried, and the dried air is further distributed to the second heat exchanger 4a for heating. The first and second air control dampers 18a, 18b can be closed and opened in different positions. When the second air control damper 18b is opened, the first air flow F1 in the first air flow channel 3a is allowed to flow into the second air flow channel 3b, where it mixes with the second air flow F2. When the second air control damper 18b is closed, the first air flow channel 3a and the second air flow channel 3b are completely separated. If the first air control damper 18a is closed, when the second air control damper 18b is in the open position, all the air in the first air flow channel 3a is directed into the second air flow channel 3b. When the first air control damper 18a is open and the second air control damper 18b is open, the air in the first air flow channel 3a is allowed to flow into the second air flow channel 3b and flow to the door unit 5 for further transportation as described above. The air in the second air flow channel 3b is transported to the door unit 5 for further transportation as described above. Figures 1a to 1c As schematically shown in FIG, the system may alternatively be configured with only the second air control damper 18b for distributing air from the first air flow channel 3a to the second air flow channel 3b.
