Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, and in particular to an air duct assembly, an air conditioner, and an air conditioner assembly system. Background Technology

[0002] The air conditioner includes a first heat exchange module and a second heat exchange module. The first heat exchange module exchanges heat with indoor air, and the second heat exchange module exchanges heat with the first heat exchange module. When the air conditioner is used for cooling, the first heat exchange module absorbs heat from the indoor air and directs the heat to the second heat exchange module. The second heat exchange module then conducts the heat to the air after the heat exchange and exhausts the air to the outside, thereby cooling the indoor air. In some scenarios, when there is no space outdoors to install the second heat exchange module, both the first and second heat exchange modules are installed in the indoor space. For example, the first and second heat exchange modules can be connected to form an integrated air conditioner, which is then installed in the space between the ceiling and the suspended ceiling. In this solution, the first heat exchange module receives indoor air and directs the heat-exchanged air indoors, while the second heat exchange module receives indoor air (which can be air from the interlayer space), exchanges heat with it, and then directs the heat-exchanged air outdoors.

[0003] In related technologies, since the second heat exchange module obtains air from the indoor space for heat exchange, when the air that has exchanged heat with the first heat exchange module is introduced into the second heat exchange module, it will reduce the heat exchange efficiency of the first heat exchange module for the indoor air, thus resulting in low heat exchange efficiency of the air conditioner for the indoor air.

The first end is used to connect to a second heat exchange module of the air conditioner, and the second end is used to obtain outdoor air. In this solution, the first air guide shell guides outdoor air to the second heat exchange module for heat exchange. Compared to a solution where both the first and second heat exchange modules are located indoors, and the second heat exchange module obtains indoor air for heat exchange, this solution improves the heat exchange efficiency of the air conditioner by preventing the air exchanged with the first heat exchange module from being discharged outdoors. Furthermore, compared to a solution where the first heat exchange module is located indoors and the second heat exchange module is located outdoors, this solution allows the second heat exchange module to be located indoors while maintaining high heat exchange efficiency, thus facilitating its installation and reducing the overall installation difficulty of the air conditioner.

[0054] Furthermore, in this solution, the first air guide shell is detachably connected to the second heat exchange module. In this solution, when the air conditioner includes the first air guide shell, on the one hand, compared to a solution where the first air guide shell is fixedly connected to the second heat exchange module, users can freely choose to install or not install the first air guide shell according to their installation scenario, thus better meeting user needs. On the other hand, when the air conditioner is to be installed in the space between the ceiling and the suspended ceiling, the first air guide shell can be separated from the second heat exchange module, and the first air guide shell and the second heat exchange module can be independently passed through the installation opening in the suspended ceiling. Then, the first air guide shell and the second heat exchange module are assembled in the space between the suspended ceiling and the suspended ceiling. This reduces the size requirement of the installation opening in the suspended ceiling for the air conditioner. With the same size installation opening, the volume of the second heat exchange module can be larger, thereby improving the heat exchange performance of the second heat exchange module.

[0091] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0092] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0093] The air conditioner includes a first heat exchange module and a second heat exchange module. The first heat exchange module exchanges heat with indoor air, and the second heat exchange module exchanges heat with the first heat exchange module. When the air conditioner is used for cooling, the first heat exchange module absorbs heat from the indoor air and directs the heat to the second heat exchange module. The second heat exchange module then conducts the heat to the air after the heat exchange and exhausts the air to the outside, thereby cooling the indoor air. In some scenarios, when there is no space outdoors to install the second heat exchange module, both the first and second heat exchange modules are installed simultaneously in the indoor space. For example, the first and second heat exchange modules can be connected to form an integrated air conditioner, which is then installed in the space between the ceiling and the suspended ceiling. In other scenarios, the first and second heat exchange modules can be installed separately in different locations indoors, connected by pipes for conducting the heat exchange medium. In this scheme, the first heat exchange module acquires indoor air and guides the heat-exchanged air into the room. The second heat exchange module acquires indoor air (which can be air from the mezzanine space), performs heat exchange, and then guides the heat-exchanged air outdoors. In related technologies, because the second heat exchange module acquires indoor air for heat exchange, when the air that has exchanged heat with the first heat exchange module is introduced into the second heat exchange module, it reduces the heat exchange efficiency of the first heat exchange module for indoor air, thus resulting in low heat exchange efficiency of the air conditioner for indoor air.

[0094] Based on this, in order to solve the technical problem that the air conditioner 10 has low heat exchange efficiency for indoor air when the second heat exchange module 300 acquires air from the indoor space 22 for heat exchange, referring to Figures 1 to 13 This utility model provides an air duct assembly 100 for use in an air conditioner 10. The air conditioner 10 includes a first heat exchange module 200 and a second heat exchange module 300, both suitable for placement in a room 22. Functionally, the first heat exchange module 200 and the second heat exchange module 300 can be respectively a conventional indoor unit and an outdoor unit of an air conditioner. The first heat exchange module 200 is used for heat exchange with indoor air, that is, the first heat exchange module 200 functions as a conventional indoor unit of an air conditioner; the second heat exchange module 300 is used for heat exchange with the first heat exchange module 200, that is, the second heat exchange module 300 functions as a conventional outdoor unit of an air conditioner (but in this embodiment, the second heat exchange module 300 is arranged indoors). The second heat exchange module 300 is provided with an air inlet 350 and an air outlet 360. The second heat exchange module 300 obtains air through the air inlet 350. After the obtained air exchanges heat with the second heat exchanger 320 of the second heat exchange module 300, it is discharged to the outside through the air outlet 360.

[0095] See Figures 1-5The air duct assembly 100 includes a first air guide shell 110, which has a first end 111 and a second end 112 that are opposite to and communicate with each other. The first end 111 has a first port 113, and the second end 112 has a second port 114. The first end 111 is adapted to be detachably connected to the second heat exchange module 300, and the first port 113 is connected to the air inlet 350. The second port 114 is adapted to obtain outdoor air. For example, the second end 112 can extend directly to the outside, so that the second port 114 can directly obtain outdoor air. Alternatively, the second end 112 can be externally connected to a connecting pipe extending to the outside, so that the second port 114 can indirectly obtain outdoor air.

[0096] Specifically, in this embodiment, when the air conditioner 10 is operating normally (taking the air conditioner 10 in cooling mode as an example), the first heat exchange module 200 can absorb the hotter air in the room 22 and cool it down. The cooled air is then blown out of the room 22 by the first heat exchange module 200. The hotter air in the room 22 circulates multiple times within the first heat exchange module 200, ultimately achieving cooling of the room 22. Simultaneously, the second heat exchange module 300 exchanges heat with the first heat exchange module 200, achieving cooling of the first heat exchange module 200 and ensuring the heat exchange effect of the first heat exchange module 200 on the indoor air. In this embodiment, the first heat exchange module 200 can absorb indoor air through the indoor air inlet 250 (the flow path of indoor air into the first heat exchange module 200 can be: indoor - indoor air inlet 250 - first heat exchange module 200). After the indoor air enters the first heat exchange module 200, it can exchange heat with the first heat exchange module 200. The indoor air after heat exchange is discharged from the first heat exchange module 200 through the indoor air outlet 260 (the flow path of indoor air discharged from the first heat exchange module 200 can be: first heat exchange module 200 - indoor air outlet 260 - indoor), thereby achieving temperature regulation of the indoor air. The second heat exchange module 300 can absorb outdoor air through the air duct assembly 100 (the flow path of outdoor air into the second heat exchange module 300 can be: outdoor - second port 114 - first port 113 - air inlet 350 - second heat exchange module 300). Outdoor air entering the second heat exchange module 300 can absorb the heat of the second heat exchange module 300 and finally discharge it into the second heat exchange module 300 to carry away the heat inside the second heat exchange module 300 (the flow path of outdoor air discharged from the second heat exchange module 300 after heat exchange is: inside the second heat exchange module 300 - air outlet 360 - outdoor), thereby achieving the cooling of the second heat exchange module 300.

[0097] In this embodiment, the first air guide shell 110 is used to guide outdoor air to the second heat exchange module 300 for heat exchange. Compared to the scheme where both the first heat exchange module 200 and the second heat exchange module 300 are located in the room 22, and the second heat exchange module 300 obtains indoor air for heat exchange, this scheme improves the heat exchange efficiency of the air conditioner 10 for indoor air because the air exchanged with the first heat exchange module 200 is not led to the outside by the second heat exchange module 300. Furthermore, since the second heat exchange module 300 does not draw in indoor air, it does not cause negative pressure in the room 22. Also, compared to the scheme where the first heat exchange module 200 is located in the room 22 and the second heat exchange module 300 is located outdoors, this scheme allows the second heat exchange module 300 to be located in the room 22 while maintaining high heat exchange efficiency, making the installation of the second heat exchange module 300 easier and reducing the overall installation difficulty of the air conditioner 10.

[0098] Furthermore, in this solution, the first air guide shell 110 is detachably connected to the second heat exchange module 300. In this solution, when the air conditioner 10 includes the first air guide shell 110, on the one hand, compared with the solution where the first air guide shell 110 is fixedly connected to the second heat exchange module 300, the user can freely choose to install the first air guide shell 110 or not install the first air guide shell 110 according to their own installation scenario, thus better meeting the user's needs. On the other hand, when the air conditioner 10 is installed in the space between the ceiling and the suspended ceiling, the first air guide shell 110 can be separated from the second heat exchange module 300. The first air guide shell 110 and the second heat exchange module 300 can then be independently passed through the installation openings in the suspended ceiling. Finally, the first air guide shell 110 and the second heat exchange module 300 can be assembled in the space between the suspended ceiling and the suspended ceiling. This reduces the size requirement of the installation opening in the suspended ceiling for the air conditioner 10. With the same size installation opening, the volume of the second heat exchange module 300 can be larger, thereby improving its heat exchange performance. Furthermore, disassembling the first air guide shell 100 facilitates subsequent cleaning and maintenance of the first air guide shell 110.

[0099] Specifically, when the first air guide shell 110 and the second heat exchange module 300 are detachably connected, the first air guide shell 110 can be connected to the second heat exchange module 300 by bolts, or the first air guide shell 110 can be snapped into the second heat exchange module 300 by a clip, or the first air guide shell 110 can be magnetically connected to the second heat exchange module 300 by a magnet.

[0100] In some embodiments, refer to Figures 1 to 5The opening area of ​​the first port 113 is larger than that of the second port 114. On the one hand, since the opening of the first port 113 is smaller, the opening in the wall through which the air duct assembly 100 penetrates can be smaller, making it easier to process the opening in the wall; on the other hand, since the opening of the second port 114 is larger, it is more conducive to the second port 114 covering the second heat exchanger 320 in the second heat exchange module 300, so that the airflow exiting the second port 114 can flow evenly through all parts of the second heat exchanger 320, improving the heat exchange efficiency of the second heat exchanger 320.

[0101] In some embodiments, refer to Figures 1-4 The first port 113 is rectangular, and the second port 114 is circular. On one hand, due to limitations in drilling equipment and to ensure the aesthetics of wall drilling, circular holes are typically made in the wall, and connecting pipes are usually circular. Corresponding to the circular hole and connecting pipe, the second port 114 can be designed as a circular structure, allowing it to better fit the circular opening in the wall, making it easier to extend to the outside or connect to an intermediate pipe. On the other hand, the second heat exchanger 320 within the second heat exchange module 300 is typically rectangular. Corresponding to the shape of the second heat exchanger 320, the air inlet 350 and the first port 113 can be designed as rectangular structures, facilitating the connection of the first port 113 to the air inlet 350.

[0102] In some embodiments, refer to Figure 1 , Figure 2 as well as Figures 5 to 13 The first air guide shell 110 also includes an intermediate section 115, one end of which is connected to the first end 111 and the other end to the second end 112. The first end 111, the intermediate section 115, and the second end 112 together form a through fluid channel. For example, the first end 111, the intermediate section 115, and the second end 112 can be an integrally formed structure to ensure the structural stability and sealing of the first air guide shell 110. Alternatively, the first end 111, the intermediate section 115, and the second end 112 can be welded together sequentially to facilitate the manufacturing, transportation, and on-site assembly of the first air guide shell 110. Along the airflow conduction direction within the first air guide shell 110, the inner diameter of the intermediate section 115 gradually increases.

[0103] Specifically, in this embodiment, outdoor air first flows into the second end 112, then through the middle section 115 into the first end 111, and finally through the first end 111 into the second heat exchange module 300. Along the airflow conduction direction within the first air guide shell 110 (when the channel within the first air guide shell 110 extends in a straight line, the airflow conduction direction is along the direction from the second end 112 to the first end 111), the inner diameter of the middle section 115 gradually increases. With this structure, on the one hand, when outdoor air flows into the middle section 115, it can gradually diffuse, thereby increasing the effective flow area of ​​outdoor air within the first air guide shell 110 and ensuring the stability and flow rate of outdoor air within the first air guide shell 110; on the other hand, after the outdoor air diffuses within the first air guide shell 110, it flows into the second heat exchange module 300 and can fully and uniformly contact the second heat exchanger 320 within the second heat exchange module 300, thereby improving the heat exchange effect of outdoor air on the second heat exchange module 300.

[0104] In the above embodiments, the inner diameters of the first end 111 and the second end 112 along the airflow conduction direction within the first air guide shell 110 can be varied as needed. See also: [link to relevant documentation] Figures 1-2 Along the airflow conduction direction within the first air guide shell 110, the inner diameters of the first end 111 and the second end 112 can remain unchanged. In other embodiments, the inner diameters of the first end 111 and the second end 112 can also gradually increase; in this case, refer to... Figure 3 and Figure 4 Along the airflow conduction direction within the first air guide shell 110, the overall inner diameter of the first air guide shell 110 gradually increases. For example, the first air guide shell 110 can be flared. By adopting the above structure, the processing flow of the first air guide shell 110 can be simplified, the processing difficulty of the first air guide shell 110 can be reduced, and the processing efficiency of the first air guide shell 110 can be improved.

[0105] In some embodiments, refer to Figures 1 to 4 The axis of the first port 113 is parallel to the axis of the second port 114 (parallelism includes coincidence). For example, the axes of the first port 113 and the second port 114 may be parallel to each other, or the axes of the first port 113 and the second port 114 may coincide. Alternatively, in some other embodiments, see [link to other embodiments]. Figure 5 The axis of the first port 113 intersects with the axis of the second port 114, or more precisely, they can be set perpendicularly. This design enables the airflow within the first air guide shell 110 to change direction, thus adapting to application scenarios requiring airflow redirection.

[0106] Specifically, in this embodiment, the first air guide shell 110 has at least two installation methods, and corresponding to the two installation methods, the first air guide shell 110 has at least two structural forms. See also Figures 1-4 One structural form of the first air guide shell 110 is a linear structure, meaning that the axis of the first port 113 is parallel (or coincident) to the axis of the second port 114. When the first air guide shell 110 adopts a linear structure, the flow direction of outdoor air within the first air guide shell 110 remains unchanged, thereby improving the smoothness of outdoor air flow and increasing the flow rate of outdoor air within the first air guide shell 110. Another structural form of the first air guide shell 110 is a non-linear structure; for example, see [link to relevant documentation]. Figure 5 The first air guide shell 110 can be a polygonal structure or a curved structure, where the axis of the first port 113 intersects the axis of the second port 114. When the first air guide shell 110 adopts a non-linear structure, it can change the flow direction of outdoor air within the first air guide shell 110, thereby adjusting the position or direction of the second port 114 relative to the first port 113. This improves the installation flexibility of the first air guide shell 110, ensuring that its installation is not limited by the indoor installation space 22, making it suitable for installation scenarios requiring precise control.

[0107] In some embodiments, refer to Figure 6 The second end 112 is configured to deform relative to the first end 111, so that the axis of the second port 114 can switch between a position perpendicular to the axis of the first port 113 and a position parallel to the axis of the first port 113. For example, the second end 112 employs a flexible structure capable of deforming relative to the first end 111. By twisting the second end 112, the orientation of the second port 114 relative to the first port 113 can be changed, allowing the axis of the second port 114 to switch back and forth between a position perpendicular to the axis of the first port 113 and a position parallel to the axis of the first port 113. This improves the installation flexibility and positional adaptability of the first air guide shell 110, ensuring that the first air guide shell 110 is not limited to the installation space and position of the indoor 22.

[0108] When a certain external force is applied to the second end 112, the second end 112 can bend or twist, causing it to deform relative to the first end 111, thereby adjusting the orientation of the second port 114 relative to the first port 113. Once the position and orientation of the second port 114 are adjusted, the external force applied to the second end 112 is removed, allowing it to remain in the adjusted position, thus achieving the positioning of the second port 114. During the adjustment of the second end 112, there is no need to disassemble or reassemble it. Under the action of external force, the second end 112 can dynamically adjust its position and direction according to actual usage requirements, improving its adjustment flexibility and applicability. After the second end 112 is adjusted, it can change the flow path and direction of outdoor air within the first air guide shell 110, ultimately achieving effective transmission or control of outdoor air to meet different application needs.

[0109] In some embodiments, refer to Figure 7 The duct assembly 100 also includes an adapter pipe 120, with a third port 121 and a fourth port 122 formed at its two ends. The axis of the third port 121 intersects the axis of the fourth port 122. One end of the adapter pipe 120 is connected to a second end 112, so that the third port 121 connects to the second port 114. The adapter pipe 120 is configured to rotate circumferentially relative to the second end 112 along the axis of the second port 114. The fourth port 122 of the adapter pipe 120 can extend directly to the outside, allowing outdoor air to flow from the fourth port 122 into the adapter pipe 120 and from the third port 121 to the second port 114, thus enabling the second port 114 to obtain outdoor air. Alternatively, the fourth port 122 of the adapter pipe 120 can be connected to a connecting pipe, with the end of the connecting pipe away from the adapter pipe 120 extending outdoors. This allows outdoor air to first flow into the connecting pipe, then from the fourth port 122 into the adapter pipe 120, and finally from the third port 121 to the second port 114, enabling the second port 114 to obtain outdoor air. Specifically, in this embodiment, by connecting the adapter pipe 120 to the second end 112, the adapter pipe 120 can change the flow direction and path of outdoor air transmitted to the second end 112, thereby changing the direction in which the second port 114 obtains outdoor air. This ensures that the second port 114 obtains outdoor air from different directions, which helps to improve the flexibility and adaptability of the duct assembly 100 in the indoor 22 installation, ensuring that the duct assembly 100 is not limited to a single installation environment and space.

[0110] By rotating the adapter pipe 120, the flow direction of outdoor air to the duct assembly 100 can be freely adjusted. Depending on the installation position of the indoor unit 22, the transmission path of outdoor air from the adapter pipe 120 to the duct assembly 100 can be dynamically adjusted, so that outdoor air can flow smoothly from the adapter pipe 120 to the duct assembly 100, thereby improving the working flexibility and adaptability of the duct assembly 100.

[0111] In some embodiments, refer to Figures 1-2 ,as well as Figure 14 and Figure 15 The second end 112 is adapted to extend outdoors so that the second port 114 (directly) obtains outdoor air. This installation method is suitable for installation environments where the duct assembly 100 is close to the wall of the interior 22, allowing the second end 112 to extend outdoors even with a relatively short length. This installation method simplifies the installation steps of the duct assembly 100, reduces the number of parts in the duct assembly 100, and improves the installation efficiency of the duct assembly 100. Furthermore, with this installation method, outdoor air can flow directly through the second port 114 into the first air guide shell 110, and then directly into the second heat exchange module 300 for heat exchange. This shortens the flow path of outdoor air into the second heat exchange module 300, improving the heat exchange efficiency of outdoor air within the second heat exchange module 300.

[0112] In some embodiments, refer to Figure 8 The air duct assembly 100 also includes a second air guide shell 130, which is a telescopic tube. One end of the second air guide shell 130 is adapted to connect to the second end 112, and the other end is adapted to extend outdoors to obtain outdoor air. Specifically, in this embodiment, the second air guide shell 130 can be in a compressed state during the installation of the air duct assembly 100 to reduce its volume, thereby facilitating the storage and transportation of the air duct assembly 100. When the air duct assembly 100 is installed indoors 22, the second air guide shell 130 can be extended to the installation position indoors 22 and extended outdoors through a through hole in the wall at the installation position indoors 22, so that outdoor air can flow through the second air guide shell 130 into the air duct assembly 100, and then flow through the air duct assembly 100 into the second heat exchange module 300 to achieve heat exchange. The second air guide shell 130 helps to improve the installation flexibility of the air duct assembly 100 in the room 22, ensuring that the air duct assembly 100 can adapt to various indoor installation environments, and enabling the air duct assembly 100 to effectively utilize the indoor space 22.

[0113] In some embodiments, refer to Figure 9The first air guide shell 110 is provided with a connecting structure 116, which is adapted to detachably connect the filter screen 117. For example, the connecting structure 116 can be a snap-fit ​​structure, allowing the filter screen 117 to snap onto the connecting structure 116. Alternatively, the connecting structure 116 can be a magnetic structure, allowing the filter screen 117 to be magnetically connected to the connecting structure 116. Alternatively, the connecting structure 116 can be an adhesive structure, allowing the filter screen 117 to be adhesively attached to the connecting structure 116. Specifically, in this embodiment, by providing a filter screen 117 inside the first air guide shell 110, impurities carried in the outdoor air (such as dust and fluff in the outdoor air) can be directly filtered out, ensuring the cleanliness of the airflow flowing into the second heat exchange module 300, thereby protecting the components inside the second heat exchange module 300 from contamination and reducing the frequency of cleaning the components inside the second heat exchange module 300. The filter screen 117 is detachably connected to the connecting structure 116, which facilitates regular cleaning of the filter screen 117 and prevents excessive impurities adsorbed on the filter screen 117 from causing blockage, affecting the air intake of outdoor air into the air duct assembly 100, and resulting in a reduction in the heat exchange efficiency of the second heat exchange module 300.

[0114] Alternatively, in some embodiments, refer to Figure 10 The air duct assembly 100 also includes a filter screen 117, which is disposed within the first air guide shell 110. For example, the filter screen 117 and the first air guide shell 110 can be an integrally formed structure. Alternatively, the filter screen 117 can be heat-fused to the first air guide shell 110. Specifically, in this embodiment, the filter screen 117 and the first air guide shell 110 are fixedly connected, which helps improve the connection stability of the filter screen 117 within the first air guide shell 110 and prevents the filter screen 117 from easily falling off the first air guide shell 110 during the handling and installation of the air duct assembly 100, thus preventing the filter screen 117 from being lost.

[0115] Correspondingly, another embodiment of this utility model also provides an air conditioner 10, see reference. Figures 11 to 13The air conditioner 10 includes a first heat exchange module 200, a second heat exchange module 300, and the air duct assembly 100 in any of the above embodiments. The first heat exchange module 200 is adapted to be installed in the room 22 and exchange heat with the air in the room 22 (in other words, the first heat exchange module 200 is functionally an indoor unit in the conventional sense). The second heat exchange module 300 is connected to the first heat exchange module 200 and adapted to be installed in the room 22. The second heat exchange module 300 is used to exchange heat with the first heat exchange module 200 (in other words, the second heat exchange module 300 is functionally an outdoor unit in the conventional sense, the difference being that in this embodiment, the second heat exchange module 300 is installed in the room 22). The second heat exchange module 300 includes an air inlet 350 and an air outlet 360, and the air outlet 360 is adapted to exhaust the air that has exchanged heat with the second heat exchange module 300 to the outside. The first end 111 of the first air guide shell 110 in the air duct assembly 100 is connected to the second heat exchange module 300 to facilitate the introduction of outdoor air into the air inlet 350. The air conditioner 10 is suitable for use scenarios where there is no space outdoors to install the second heat exchange module 300, such as in a kitchen, a motorhome, or a ship.

[0116] Specifically, in this embodiment, by adding the air duct assembly 100, the second heat exchange module 300 can absorb outdoor air and utilize the circulation of outdoor air within the second heat exchange module 300 to achieve heat exchange. Compared to the second heat exchange module 300 absorbing indoor air for heat exchange, the solution provided in this embodiment, on the one hand, avoids the second heat exchange module 300 absorbing air that has already undergone heat exchange in the indoor 22, thereby ensuring the cooling or heating effect of the indoor 22 and improving the comfort of the indoor 22; on the other hand, it avoids the second heat exchange module 300 absorbing air from the indoor 22, which would cause a decrease in the air pressure in the indoor 22 and affect the normal activities of users in the indoor 22.

[0117] In some embodiments, refer to Figure 11 and Figure 12The first heat exchange module 200 includes a first outer shell 210 and a first heat exchanger 220. The first outer shell 210 has a first cavity 240, and the first heat exchanger 220 is disposed within the first cavity 240. The second heat exchange module 300 includes a second outer shell 310 and a second heat exchanger 320. The second outer shell 310 has a second cavity 340, and the second heat exchanger 320 is disposed within the second cavity 340. The second outer shell 310 has an air inlet 350 and an air outlet 360 communicating with the second cavity 340. In this embodiment, the first outer shell 210 and the second outer shell 310 are connected to each other through a bottom panel. In other embodiments, the first outer shell 210 and the second outer shell 310 can also be spaced apart from each other, and the two are distributed in two different locations in the room 22. Specifically, in this embodiment, indoor air can only be absorbed into the first outer shell 210. After heat exchange with the first heat exchanger 220, the heat-exchanged indoor air can be discharged from the first outer shell 210 into the room 22. Outdoor air can only be drawn into the second outer shell 310. After heat exchange with the second heat exchanger 320, the heat-exchanged outdoor air can be discharged to the outside through the second outer shell 310. Therefore, the heat exchange processes of indoor and outdoor air are independent and do not interfere with each other, thus improving the heat exchange efficiency and stability of indoor air. At the same time, since indoor and outdoor air do not mix during the heat exchange process, the cleanliness of indoor air is ensured.

[0118] In some embodiments, refer to Figure 13 The first heat exchange module 200 includes a first shell portion 230 and a first heat exchanger 220. The second heat exchange module 300 includes a second shell portion 330 and a second heat exchanger 320. The first shell portion 230 and the second shell portion 330 are combined to form a third outer shell 400. The third outer shell 400 has a third cavity 410. The first heat exchanger 220 and the second heat exchanger 320 are both disposed within the third cavity 410. The second shell portion 330 has an air inlet 350 and an air outlet 360. In this embodiment, the first heat exchanger 220 and the second heat exchanger 320 are both disposed within the same cavity, which can improve the overall structural integrity of the air conditioner 10, simplify the manufacturing and assembly process of the air conditioner 10, and improve the manufacturing and assembly efficiency of the air conditioner 10. At the same time, it is beneficial to reduce the overall volume of the air conditioner 10.

[0119] In some embodiments, refer to Figure 15The second heat exchange module 300 includes a second housing 310 and a second heat exchanger 320. The second housing 310 has a second cavity 340, and the second heat exchanger 320 is disposed within the second cavity 340. The second housing 310 has an air inlet 350 and an air outlet 360 communicating with the second cavity 340. The air inlet 350 and the air outlet 360 are both disposed on the same plate of the second housing 310. Alternatively, the air inlet 350 and the air outlet 360 are respectively disposed on two adjacent or opposite plates of the second housing 310, and the second end 112 extends to such that the second port 114 and the air outlet 360 face the same side of the second housing 310.

[0120] When the air inlet 350 and the air outlet 360 are respectively located on different sides of the second housing 310, by using the second end 112 to orient the second port 114 and the air outlet 360 toward the same side of the second housing 310, it is actually possible to allow outdoor air to enter or exit the second cavity 340 from the same side of the second housing 310 (the flow path of outdoor air into the second cavity 340 is: second port 114 - first port 113 - air inlet 350 - second cavity 340).

[0121] In some embodiments, the air conditioner 10 is adapted to be at least partially installed in the interlayer space between the suspended ceiling and the ceiling of the kitchen. Specifically, in this embodiment, there is usually an interlayer space with a certain capacity between the suspended ceiling and the ceiling of the kitchen. Installing the air conditioner 10 in the aforementioned interlayer space is beneficial for making use of the limited space in the kitchen, saving the usable area of ​​the kitchen, and at the same time, it is also beneficial for hiding the air conditioner 10 in the interlayer space, thereby improving the aesthetics of the kitchen.

[0122] See Figure 16In some embodiments, when the air conditioner 10 is installed in the space between the suspended ceiling 25 and the ceiling, the suspended ceiling 25 includes a keel support 251 and a plurality of ceiling panels. The keel support 251 includes a plurality of staggered keels 253, each keel 253 defining a plurality of mounting openings 252. Each ceiling panel is connected to the keel support 251 and correspondingly covers each mounting opening 252. In particular, in this embodiment, the first outer shell 210 of the first heat exchange module 200 and the second outer shell 310 of the second heat exchange module 300 are spaced apart. Both the first outer shell 210 and the second outer shell 310 are adapted to pass through the mounting openings 252, and the gap between the first outer shell 210 and the second outer shell 310 is adapted to accommodate the keels 253 of the keel support 251 (i.e., a clearance gap 600 is formed between the first outer shell 210 and the second outer shell 310, and the clearance gap 600 is adapted to accommodate the keels 253 of the suspended ceiling). In this solution, when installing the air conditioner 10, it is not necessary to cut the keel 253. The two ceiling panels can be removed directly, and the air conditioner can be installed from bottom to top. The first outer shell 210 passes through one of the installation holes 252, and the second outer shell 310 passes through another adjacent installation hole 252. This allows the keel 253 between the first outer shell 210 and the second outer shell 310 to be retained without cutting. Furthermore, in this scheme, since the first air guide shell 110 and the second outer shell 310 are detachably connected, if the two shells cannot pass through the mounting opening 252 after the second outer shell 310 is connected to the first air guide shell 110, the first air guide shell 110 can be disassembled from the second outer shell 310 and passed through the mounting opening 252 with the first air guide shell 110 facing upwards. Then, the second outer shell 310 can be passed through the mounting opening 252 with the second outer shell facing upwards. The first air guide shell 110 and the second outer shell 310 are connected in the interlayer space between the suspended ceiling 25 and the ceiling, thereby realizing the overall installation of the air conditioner 10. This scheme also eliminates the need to cut the keel 253, improving the overall structural stability of the suspended ceiling 25.

[0123] In some embodiments, refer to Figure 17 The air conditioner 10 also includes a base 11. A first outer shell 210 is connected to the base 11 and together with the base 11 forms a first cavity 240. A second outer shell 310 is connected to the base 11 and together forms a second cavity 340. The first outer shell 210 and the second outer shell 310 are spaced apart. A clearance gap 600 is formed between the side plate of the first outer shell 210 near the second outer shell 310, the side plate of the second outer shell 310 near the first outer shell 210, and the base 11. That is, both the first outer shell 210 and the second outer shell 310 are connected to the base 11. Alternatively, in some embodiments, the first outer shell 210 and the second outer shell 310 are integrally connected and together form an outer shell body. The top of the outer shell body is recessed downward to form a clearance gap 600 for the keel 253 to pass through. That is, the first outer shell 210 and the second outer shell 310 are integrally formed structures.

[0124] Specifically, in this embodiment, the top of the outer casing of the air conditioner 10 is provided with a downwardly recessed clearance 600, which is used to accommodate the keel support 251 for the keel support 251 to pass through. In other words, the first outer casing 210 of the first heat exchange module 200 and the second outer casing 310 of the second heat exchange module 300 are spaced apart, and the downwardly recessed clearance 600 is formed at the interval between the first outer casing 210 and the second outer casing 310. The first outer casing 210 and the second outer casing 310 are respectively located on opposite sides of the clearance 600. Preferably, the clearance 600 can be a straight groove to facilitate the assembly between the air conditioner 10 and the keel support 251. The clearance 600 can extend from one side of the casing to the other side of the casing, and the clearance 600 penetrates the casing in the horizontal direction. The depth of the clearance 600 can be 80% to 95% of the vertical dimension of the casing.

[0125] The specific dimensions of the first outer casing 210 in some embodiments are described below. The width of the first outer casing 210 in the lateral direction can be between 260mm and 265mm. For example, the width of the first outer casing 210 in the lateral direction can be 260mm, 262mm, 264mm, or 265mm, etc. In this embodiment, the lateral dimension of the first outer casing 210 is smaller than the size of the mounting opening 252, which facilitates the assembly and disassembly of the first heat exchange module 200. In other embodiments, the width of the first outer casing 210 in the lateral direction can be between 265mm and 300mm. For example, the width of the first outer casing 210 in the lateral direction can be 265mm, 270mm, 285mm, 290mm, or 300mm, etc. In this embodiment, the lateral dimension of the first outer casing 210 is larger than the size of the mounting opening 252, which allows the first heat exchange module 200 to be set to a larger volume, thereby enhancing the heat exchange effect of the air conditioner 10. It should be noted that when the first outer shell 210 is larger than the size of the mounting opening 252 in the lateral direction, when installing the first heat exchange module 200, the first outer shell 210 can be tilted in the lateral direction first, so that the end of the first outer shell 210 located at the higher position in the lateral direction passes through the mounting opening 252 first. Then, the first outer shell 210 is pushed in in the lateral direction, so that the end of the first outer shell 210 located at the lower position in the lateral direction passes through the mounting opening 252, so that the first heat exchange module 200 is installed between the ceiling and the suspended ceiling 25.

[0126] In some embodiments, the lateral length of the first outer casing 210 can be between 500mm and 600mm. For example, the lateral length of the first outer casing 210 can be 500mm, 510mm, 525mm, 548mm, 570mm, 583mm, 596mm, or 600mm, etc. In this solution, the lateral length of the first outer casing 210 is smaller than the size of the mounting opening 252, facilitating the assembly and disassembly of the first heat exchange module 200. In other embodiments, the lateral width of the first outer casing 210 can be between 600mm and 631mm. For example, the lateral width of the first outer casing 210 can be 600mm, 605mm, 614mm, 620mm, 625mm, or 631mm, etc. In this solution, the lateral length of the first outer casing 210 is larger than the size of the mounting opening 252, allowing the first heat exchange module 200 to be configured with a larger volume, thereby enhancing the heat exchange effect of the air conditioner 10. It should be noted that when the length of the first outer shell 210 in the horizontal direction is greater than the size of the mounting opening 252, when installing the first heat exchange module 200, the first outer shell 210 can be tilted in the horizontal direction first, so that the end of the first outer shell 210 located at the higher position in the horizontal direction passes through the mounting opening 252 first, then the first outer shell 210 is pushed in in the horizontal direction, and then the end of the first outer shell 210 located at the lower position in the horizontal direction passes through the mounting opening 252, so that the first heat exchange module 200 is installed between the ceiling and the suspended ceiling 25.

[0127] The specific dimensions of the second housing 310 in some embodiments are described below. The width of the second housing 310 in the lateral direction can be between 260mm and 265mm. For example, the width of the second housing 310 in the lateral direction can be 260mm, 262mm, 264mm, or 265mm, etc. In this embodiment, the lateral dimension of the second housing 310 is smaller than the size of the mounting opening 252, which facilitates the assembly and disassembly of the second heat exchange module 300. In other embodiments, the width of the second housing 310 in the lateral direction can be between 265mm and 300mm. For example, the width of the second housing 310 in the lateral direction can be 265mm, 270mm, 285mm, 290mm, or 300mm, etc. In this embodiment, the lateral dimension of the second housing 310 is larger than the size of the mounting opening 252, which allows the second heat exchange module 300 to be set to a larger volume, thereby enhancing the heat exchange effect of the air conditioner 10. It should be noted that when the second outer shell 310 is larger than the size of the mounting opening 252 in the lateral direction, when installing the second heat exchange module 300, the second outer shell 310 can be tilted in the lateral direction first, so that the end of the second outer shell 310 located at the higher position in the lateral direction passes through the mounting opening 252. Then, the second outer shell 310 is pushed in in the lateral direction, so that the end of the second outer shell 310 located at the lower position in the lateral direction passes through the mounting opening 252, so that the second heat exchange module 300 is installed between the ceiling and the suspended ceiling 25.

[0128] In some embodiments, the lateral length of the second housing 310 can be between 500mm and 600mm. For example, the lateral length of the second housing 310 can be 500mm, 510mm, 525mm, 548mm, 570mm, 583mm, 596mm, or 600mm, etc. In this solution, the lateral length of the second housing 310 is smaller than the size of the mounting opening 252, facilitating the assembly and disassembly of the second heat exchange module 300. In other embodiments, the lateral width of the second housing 310 can be between 600mm and 631mm. For example, the lateral width of the second housing 310 can be 600mm, 605mm, 614mm, 620mm, 625mm, or 631mm, etc. In this solution, the lateral length of the second housing 310 is larger than the size of the mounting opening 252, allowing the second heat exchange module 300 to be configured with a larger volume, thereby enhancing the heat exchange effect of the air conditioner 10. It should be noted that when the length of the second outer shell 310 in the lateral direction is greater than the size of the mounting opening 252, when installing the second heat exchange module 300, the second outer shell 310 can be tilted in the lateral direction first, so that the end of the second outer shell 310 located at the higher position in the lateral direction passes through the mounting opening 252 first. Then, the second outer shell 310 is pushed in in the lateral direction, so that the end of the second outer shell 310 located at the lower position in the lateral direction passes through the mounting opening 252, so that the second heat exchange module 300 is installed between the ceiling and the suspended ceiling 25.

[0129] The following describes some specific dimensions (including mounting brackets) of the air conditioner 10 in various embodiments. The overall length of the air conditioner 10 can be between 575mm and 590mm. For example, the overall length of the air conditioner 10 can be 575mm, 580mm, 583mm, 585mm, 588mm, or 590mm, etc. The overall width of the air conditioner 10 can be between 550mm and 565mm. For example, the overall width of the air conditioner 10 can be 550mm, 553mm, 555mm, 560mm, 563mm, or 565mm, etc. The overall height of the air conditioner 10 can be between 250mm and 265mm.

[0130] Reference Figures 14-16Another embodiment of this utility model provides an air conditioner assembly system 1, which includes the air conditioner 10 in any of the above embodiments. The air conditioner assembly system 1 also includes a mounting carrier 20, which includes multiple wall panels that together enclose an indoor space 22. A first heat exchange module 200 and a second heat exchange module 300 are disposed within the indoor space 22. One wall panel has a first opening 23 communicating with the indoor space 22, and another wall panel (which may be the same wall panel as the aforementioned wall panels or a different wall panel) has a second opening 24 communicating with the indoor space 22. For example, see [link to example]. Figure 15 The first opening 23 and the second opening 24 can both be located on the same wall panel 21a. The first air guide shell 110 and the third air guide shell 500 both pass through the wall panel 21a to communicate with the outdoor air. (See also...) Figure 14 In other embodiments, the first opening 23 and the second opening 24 may be provided on different wall panels. Specifically, the first opening 23 is provided on wall panel 21a, the second opening 24 is provided on wall panel 21b, the first air guide shell 110 passes through the first opening 23 on wall panel 21a to communicate with the outside, and the third air guide shell 500 passes through the second opening 24 on wall panel 21b to communicate with the outside.

[0131] It should be noted that the mounting carrier 20 can be a building, a motorhome, or a ship hull. When the mounting carrier 20 is a building, the wall panel can be a wall; when the mounting carrier is a motorhome or ship hull, the wall panel can be a panel structure used to enclose the interior space of the motorhome or ship hull.

[0132] In this embodiment, by providing the air duct assembly 100, the distance between the air inlet 350 and the first opening 23 of the second heat exchange module 300 can be extended. By providing the third air guide shell 500, the distance between the air outlet 360 and the second opening 24 of the second heat exchange module 300 can be extended. This ensures that the installation position of the air conditioner 10 in the indoor space 22 is not limited to the opening positions of the first opening 23 and the second opening 24, thereby improving the installation flexibility of the air conditioner 10 in the indoor space 22. For example, see... Figure 14 The air conditioner 10 can be installed in the indoor space 22 of the mounting carrier 20 near the wall panel; see [link / reference]. Figure 15 The air conditioner 10 can be installed in the middle of the indoor space 22 of the mounting carrier 20 (that is, the air conditioner 10 is installed in the indoor space 22 of the mounting carrier 20 away from the wall panel).

[0133] Thanks to the improvements to the aforementioned air duct assembly 100, the air conditioner 10 and air conditioner assembly system 1 of this embodiment have the same technical effects as the aforementioned air duct assembly 100, which will not be repeated here. It should be noted that other contents of the air duct assembly 100, air conditioner 10 and air conditioner assembly system 1 disclosed in this utility model can be found in the prior art, which will not be repeated here.

[0134] It should be noted that if any directional indication (such as up, down, left, right, front, back, etc.) is involved in the embodiments of this utility model, such directional indication is only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indication will also change accordingly. When a directional reference is introduced in a specific embodiment, unless the direction is specifically limited to unidirectional, the direction can be unidirectional or bidirectional (two parallel and opposite directions). Whether it is unidirectional or bidirectional depends on what those skilled in the art can achieve. When the directional reference is bidirectional, it should be considered that two parallel and different embodiments have been introduced simultaneously.

[0135] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or," "and / or," or "and / or" throughout the text implies three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where A and B are simultaneously satisfied. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0136] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
