[0002] An air conditioner includes a first heat exchange module and a second heat exchange module. Among them, the first heat exchange module is used for heat exchange with indoor air, and the second heat exchange module is used for heat exchange with the first heat exchange module. When the air conditioner is used for refrigeration, the first heat exchange module can be used to absorb the heat of the indoor air and direct the heat to the second heat exchange module. The second heat exchange module conducts the heat to the air after heat exchange with it and then discharges the air to the outside, so as to realize the refrigeration of the indoor air. In some scenarios, when there is no space to install the second heat exchange module outdoors, the first heat exchange module and the second heat exchange module are both arranged in the indoor space. Exemplarily, the first heat exchange module and the second heat exchange module can be connected to form an integrated air conditioner, and the air conditioner is installed in the space between the indoor ceiling and the suspended ceiling. In this solution, the first heat exchange module obtains the indoor air and directs the heat-exchanged air indoors. After the second heat exchange module obtains the indoor air (which can be the air in the interlayer space) and exchanges heat, it directs the heat-exchanged air outdoors.

Compared with the solution in which the first heat exchange module and the second heat exchange module are both arranged indoors, and the second heat exchange module obtains indoor air and performs heat exchange, in this solution, since the air that exchanges heat with the first heat exchange module will not be led out of the room by the second heat exchange module, the heat exchange efficiency of the air conditioner for indoor air can be improved. At the same time, compared with the solution in which the first heat exchange module is arranged indoors and the second heat exchange module is arranged outdoors, this solution can arrange the second heat exchange module indoors while ensuring a relatively high heat exchange efficiency, thus making it more convenient to install the second heat exchange module and reducing the overall installation difficulty of the air conditioner.

In this solution, when the air conditioner includes the first air guide housing, on the one hand, compared with the solution in which the first air guide housing is fixedly connected to the second heat exchange module, the user can freely choose to install or not install the first air guide housing according to their installation scenario, thus better adapting to the user's 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 housing and the second heat exchange module can be separated first, and then the first air guide housing and the second heat exchange module are respectively passed through the installation opening of the suspended ceiling independently, and then the first air guide housing and the second heat exchange module are assembled in the sandwich space between the suspended ceiling and the ceiling, so as to reduce the size requirement of the installation opening of the suspended ceiling for the air conditioner. Under the same size of the 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, functional features and advantages of the object of the present invention will be further described with reference to the embodiments and the accompanying drawings. Detailed implementation manners

[0092] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0093] The air conditioner includes a first heat exchange module and a second heat exchange module. Among them, the first heat exchange module is used to perform heat exchange on the indoor air, and the second heat exchange module is used to perform heat exchange with the first heat exchange module. When the air conditioner is used for refrigeration, the first heat exchange module can be used to absorb the heat of the indoor air and direct the heat to the second heat exchange module. The second heat exchange module conducts the heat to the air after heat exchange with it and then discharges the air to the outside, so as to realize the refrigeration of the indoor air. In some scenarios, when there is no space for installing the second heat exchange module outdoors, the first heat exchange module and the second heat exchange module are both arranged in the indoor space. Exemplarily, the first heat exchange module and the second heat exchange module can be connected to form an integrated air conditioner, and the air conditioner is installed in the space between the indoor ceiling and the suspended ceiling. In other scenarios, the first heat exchange module and the second heat exchange module can also be installed at different positions indoors, and the two are connected by a pipe body for conducting the heat exchange medium. In this solution, the first heat exchange module obtains the indoor air and directs the air after heat exchange indoors. After the second heat exchange module obtains the indoor air (which can be the air in the interlayer space) and performs heat exchange, it directs the air after heat exchange outdoors. In the related art, since the second heat exchange module obtains the indoor air for heat exchange, when the air after heat exchange with the first heat exchange module is introduced into the second heat exchange module, the heat exchange efficiency of the first heat exchange module for the indoor air will be reduced, resulting in low heat exchange efficiency of the air conditioner for the indoor air.

[0094] Based on this, in order to solve the technical problem that the heat exchange efficiency of the air conditioner 10 for the indoor air is low when the second heat exchange module 300 currently obtains the indoor 22 space air for heat exchange, refer to Figures 1 to 13 , an embodiment of the present invention provides an air duct assembly 100, which is used for the air conditioner 10. The air conditioner 10 includes a first heat exchange module 200 and a second heat exchange module 300 that are both suitable for being arranged indoors 22. Functionally, the first heat exchange module 200 and the second heat exchange module 300 can be respectively a traditional air conditioner indoor unit and an air conditioner outdoor unit. The first heat exchange module 200 is used to perform heat exchange on the indoor air, that is, the first heat exchange module 200 is a traditional air conditioner indoor unit in function; the second heat exchange module 300 is used to perform heat exchange with the first heat exchange module 200, that is, the second heat exchange module 300 is a traditional air conditioner outdoor unit in function (but the second heat exchange module 300 in this embodiment 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, and after the obtained air performs heat exchange with the second heat exchanger 320 of the second heat exchange module 300, it is discharged outdoors through the air outlet 360.

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

[0096] Specifically, in this embodiment, when the air conditioner 10 is operating normally (taking the refrigeration of the air conditioner 10 as an example), the first heat exchange module 200 can absorb the air with higher heat in the room 22 and exchange heat to cool the air with higher heat. The cooled air is blown out by the first heat exchange module 200 into the room 22. The air with higher heat in the room 22 circulates multiple times in the first heat exchange module 200, and finally the cooling of the room 22 is realized. At the same time, the second heat exchange module 300 exchanges heat with the first heat exchange module 200 to realize the cooling of the first heat exchange module 200 and ensure 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 portion 250 (the flow path of the indoor air flowing into the first heat exchange module 200 can be: indoor - indoor air inlet portion 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 portion 260 (the flow path of the indoor air discharged from the first heat exchange module 200 can be: first heat exchange module 200 - indoor air outlet portion 260 - indoor), realizing the temperature adjustment of the indoor air. The second heat exchange module 300 can absorb outdoor air through the air duct assembly 100 (the flow path of the outdoor air flowing into the second heat exchange module 300 can be: outdoor - second port 114 - first port 113 - air inlet 350 - second heat exchange module 300). The outdoor air entering the second heat exchange module 300 can absorb the heat of the second heat exchange module 300 and finally be discharged from the second heat exchange module 300 to take out the heat in the second heat exchange module 300 (the flow path of the outdoor air after heat exchange discharged from the second heat exchange module 300 is: inside the second heat exchange module 300 - air outlet 360 - outdoor), realizing the cooling of the second heat exchange module 300.

[0097] In this embodiment, the first air guide housing 110 is used to direct outdoor air to the second heat exchange module 300 and perform heat exchange with the second heat exchange module 300. Compared with the solution where the first heat exchange module 200 and the second heat exchange module 300 are both arranged indoors 22, and the second heat exchange module 300 obtains indoor air for heat exchange, in this solution, since the air that exchanges heat with the first heat exchange module 200 will not be discharged outdoors by the second heat exchange module 300, the heat exchange efficiency of the air conditioner 10 for indoor air can be improved. Moreover, since the second heat exchange module 300 does not suck indoor air, it will not cause negative pressure in the room 22. At the same time, compared with the solution where the first heat exchange module 200 is arranged indoors 22 and the second heat exchange module 300 is arranged outdoors, this solution can arrange the second heat exchange module 300 indoors 22 on the premise of ensuring a relatively high heat exchange efficiency, which is more convenient for the installation of the second heat exchange module 300 and reduces the overall installation difficulty of the air conditioner 10.

[0098] Further, in this solution, the first air guide housing 110 is detachably connected to the second heat exchange module 300. In this solution, when the air conditioner 10 includes the first air guide housing 110, on the one hand, compared with the solution where the first air guide housing 110 is fixedly connected to the second heat exchange module 300, the user can freely choose to install the first air guide housing 110 or not according to their installation scenario, so as to better meet the user's needs. On the other hand, when the air conditioner 10 is to be installed in the space between the ceiling and the suspended ceiling, the first air guide housing 110 can be separated from the second heat exchange module 300 first, and then the first air guide housing 110 and the second heat exchange module 300 are respectively independently passed through the installation opening of the suspended ceiling, and then the first air guide housing 110 and the second heat exchange module 300 are assembled in the sandwich space between the suspended ceiling and the ceiling, so as to reduce the size requirement of the installation opening of the air conditioner 10 for the suspended ceiling. Under the same size of the installation opening, the volume of the second heat exchange module 300 can be larger, thereby improving the heat exchange performance of the second heat exchange module 300. On the other hand, by disassembling the first air guide housing 100, it is also convenient for subsequent cleaning and maintenance of the first air guide housing 110.

[0099] Specifically, when the first air guide housing 110 and the second heat exchange module 300 are detachably connected, the first air guide housing 110 can be connected to the second heat exchange module 300 by bolts, or the first air guide housing 110 can be snap-connected to the second heat exchange module 300 by snap blocks, or the first air guide housing 110 can be magnetically attracted to the second heat exchange module 300 by magnets.

[0100] In some embodiments, refer to Figures 1 to 5, the opening area of ​​the first port 113 is larger than the opening area of ​​the second port 114. On the one hand, since the opening of the first port 113 is smaller, the opening on the wall through which the air duct assembly 100 is penetrated can be smaller, which is more convenient for processing the opening on 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 derived from the second port 114 can flow evenly through all parts of the second heat exchanger 320, thereby improving the heat exchange efficiency of the second heat exchanger 320.

[0101] In some embodiments, reference Figures 1 - 4 , the first port 113 is rectangular, and the second port 114 is circular. On the one hand, due to the limitations of the punching equipment and to ensure the aesthetics of the wall punching, a circular hole is usually opened in the wall, and the connecting pipe is usually a circular pipe. Corresponding to the circular hole and the connecting pipe, the second port 114 can be designed as a circular structure, so that the second port 114 can better fit the circular opening on the wall, making it easier for the second port 114 to pass through the outdoors, or making it easier for the second port 114 to connect to the intermediate pipe. On the other hand, the second heat exchanger 320 in the second heat exchange module 300 is usually a rectangular structure. Corresponding to the structural shape of the second heat exchanger 320, the air inlet 350 and the first port 113 can be designed as a rectangular structure shape, which is more convenient for the first port 113 to connect to the air inlet 350.

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

[0103] Specifically, in this embodiment, the outdoor air first flows into the second end portion 112, then flows into the first end portion 111 via the middle section 115, and finally flows into the second heat exchange module 300 via the first end portion 111. Along the air flow conduction direction in the first air guide housing 110 (when the channel in the first air guide housing 110 extends in a straight line, the air flow conduction direction is from the second end portion 112 to the first end portion 111), the inner diameter of the middle section 115 gradually increases. With the above structure, on the one hand, when the outdoor air flows into the middle section 115, it can gradually diffuse, which is beneficial to increasing the effective flow area of the outdoor air in the first air guide housing 110 and ensuring the smoothness and flow rate of the outdoor air flow in the first air guide housing 110; on the other hand, after the outdoor air diffused in the first air guide housing 110 flows into the second heat exchange module 300, it can fully and evenly contact the second heat exchanger 320 in the second heat exchange module 300, which is beneficial to improving the heat exchange effect of the outdoor air on the second heat exchange module 300.

[0104] In the above embodiment, along the air flow conduction direction in the first air guide housing 110, the inner diameter changes of the first end portion 111 and the second end portion 112 can be determined as needed. In some embodiments, referring to Figures 1 - 2 , along the air flow conduction direction in the first air guide housing 110, the inner diameters of the first end portion 111 and the second end portion 112 can remain unchanged. In other embodiments, the inner diameters of the first end portion 111 and the second end portion 112 can also gradually increase. At this time, referring to Figure 3 and Figure 4 , along the air flow conduction direction in the first air guide housing 110, the overall inner diameter of the first air guide housing 110 gradually increases. Exemplarily, for example, the first air guide housing 110 as a whole can be in a horn shape. With the above structure, the processing process of the first air guide housing 110 can be simplified, the processing difficulty of the first air guide housing 110 can be reduced, and the processing efficiency of the first air guide housing 110 can be improved.

[0105] In some embodiments, referring to Figures 1 to 4 , the axis of the first port 113 is parallel to the axis of the second port 114 (the parallel setting of the two includes their coincidence). For example, the axis of the first port 113 and the axis of the second port 114 can be parallel to each other, or the axis of the first port 113 and the axis of the second port 114 can coincide. Or, in other embodiments, referring to Figure 5 , the axis of the first port 113 intersects with the axis of the second port 114, specifically, it can be perpendicularly set. This solution can achieve the redirection of the air flow in the first air guide housing 110, so as to adapt to the application scenarios that require air flow redirection.

[0106] Specifically, in this embodiment, the first air guide housing 110 has at least two installation methods. Corresponding to the above two installation methods, the first air guide housing 110 has at least two structural forms. Refer to Figures 1 - 4 , one of the structural forms of the first air guide housing 110 is a linear structure, that is, the axis of the first port 113 is parallel (including coincident) with the axis of the second port 114. When the first air guide housing 110 adopts a linear structure, the flow direction of the outdoor air does not change when flowing in the first air guide housing 110, which is beneficial to improving the flow smoothness of the outdoor air in the first air guide housing 110 and increasing the flow rate of the outdoor air in the first air guide housing 110. Another structural form of the first air guide housing 110 is a non-linear structure. Exemplarily, for example, refer to Figure 5 , the structural form of the first air guide housing 110 can be a folded line structure, or the structural form of the first air guide housing 110 can also be a curved line structure, that is, the axis of the first port 113 intersects with the axis of the second port 114. When the first air guide housing 110 adopts a non-linear structure, it can change the flow direction of the outdoor air when flowing in the first air guide housing 110, so as to adjust the position or direction of the second port 114 relative to the first port 113, improve the installation flexibility of the first air guide housing 110, ensure that the first air guide housing 110 is not limited by the installation space of the room 22 during installation, and make the first air guide housing 110 suitable for installation scenarios that require precise regulation.

[0107] In some embodiments, refer to Figure 6 , the second end 112 is configured to be deformable relative to the first end 111, so that the axis of the second port 114 can be switched between a position perpendicular to the axis of the first port 113 and a position parallel to the axis of the first port 113. Exemplarily, the second end 112 adopts a flexible structure that can deform 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, so that the axis of the second port 114 can be switched 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, which is beneficial to improving the installation flexibility and position adaptability of the first air guide housing 110 and ensuring that the first air guide housing 110 is not limited to the installation space and installation position of the room 22.

[0108] When a certain external force is applied to the second end portion 112, the second end portion 112 can be bent or twisted, so that the second end portion 112 can be deformed relative to the first end portion 111, and further the orientation of the second port 114 relative to the first port 113 can be adjusted. After the position and orientation of the second port 114 are adjusted, the external force applied to the second end portion 112 is withdrawn, so that the second end portion 112 is maintained at the adjusted position, realizing the positioning of the second port 114. During the adjustment of the second end portion 112, there is no need to disassemble or reassemble the second end portion 112. Under the action of the external force, the second end portion 112 can dynamically adjust its position and direction according to the actual use requirements, improving the adjustment flexibility and applicability of the second end portion 112. After the second end portion 112 is adjusted, it can change the flow path and flow direction of the outdoor air in the first air guide housing 110, and finally realize the effective transmission or regulation of the outdoor air, so as to meet different application requirements.

[0109] In some embodiments, referring to Figure 7 , the air duct assembly 100 further includes a transition pipe 120. The two ends of the transition pipe 120 respectively form a third port 121 and a fourth port 122. The axis of the third port 121 intersects with the axis of the fourth port 122. One end of the transition pipe 120 is connected to the second end portion 112 so that the third port 121 communicates with the second port 114. The transition pipe 120 is configured to be able to rotate circumferentially along the axis of the second port 114 relative to the second end portion 112. The fourth port 122 end of the transition pipe 120 can directly extend out of the room, so that the outdoor air flows into the transition pipe 120 from the fourth port 122 and flows from the third port 121 to the second port 114, realizing the acquisition of outdoor air by the second port 114. Or, the fourth port 122 of the transition pipe 120 can be connected to a connecting pipe, and the end of the connecting pipe away from the transition pipe 120 extends out of the room, so that the outdoor air first flows into the connecting pipe, then flows into the transition pipe 120 from the fourth port 122, and finally flows from the third port 121 to the second port 114, realizing the acquisition of outdoor air by the second port 114. Specifically, in this embodiment, by externally connecting the transition pipe 120 to the second end portion 112, the transition pipe 120 can change the flow direction and flow path of the outdoor air transmitted to the second end portion 112, and further can change the direction of the second port 114 to obtain outdoor air, ensuring that the second port 114 obtains outdoor air from different directions, which is beneficial to improving the installation flexibility and adaptability of the air duct assembly 100 in the room 22 and ensuring that the air duct assembly 100 is not limited to a single installation environment and installation space.

[0110] By rotating the adapter tube 120, the flow direction of outdoor air flowing into the duct assembly 100 can be freely adjusted and changed. According to the installation position of the indoor unit 22, the dynamic adjustment of the transmission path of outdoor air from the adapter tube 120 to the duct assembly 100 can be realized, so that the outdoor air can smoothly flow from the adapter tube 120 to the duct assembly 100, improving the working flexibility and adaptability of the duct assembly 100.

[0111] In some embodiments, referring to Figures 1 - 2 , and Figure 14 and Figure 15 , the second end portion 112 is adapted to pass through the outside of the room so that the second port 114 can directly obtain outdoor air. The above installation method is suitable for the installation environment where the duct assembly 100 is close to the wall of the indoor unit 22, so that the second end portion 112 can pass through the outside of the room with a relatively short length. By adopting the above installation method, it is beneficial to simplify the installation steps of the duct assembly 100, reduce the number of parts of the duct assembly 100, and improve the installation efficiency of the duct assembly 100. In addition, by adopting the above installation method, outdoor air can directly flow into the first air guide housing 110 through the second port 114, and directly flow into the second heat exchange module 300 through the first air guide housing 110 for heat exchange, which is beneficial to shortening the flow path of outdoor air flowing into the second heat exchange module 300 and improving the heat exchange efficiency of outdoor air in the second heat exchange module 300.

[0112] In some embodiments, referring to Figure 8 , the duct assembly 100 further includes a second air guide housing 130. The second air guide housing 130 is a telescopic tube. One end of the second air guide housing 130 is adapted to be connected to the second end portion 112, and the other end is adapted to pass through the outside of the room to obtain outdoor air. Specifically, in this embodiment, before installing the duct assembly 100, the second air guide housing 130 can be in a compressed state to reduce the volume of the second air guide housing 130, so as to facilitate the storage and transportation of the duct assembly 100. When installing the duct assembly 100 in the indoor unit 22, the second air guide housing 130 can be extended to the installation position in the indoor unit 22, and the second air guide housing 130 can be extended to the outside of the room through the through hole in the wall at the installation position in the indoor unit 22, so that outdoor air can flow into the duct assembly 100 through the second air guide housing 130, and then flow into the second heat exchange module 300 through the duct assembly 100 for heat exchange. Through the second air guide housing 130, it is beneficial to improve the installation flexibility of the duct assembly 100 in the indoor unit 22, ensure that the duct assembly 100 can adapt to various installation environments in the indoor unit 22, and enable the duct assembly 100 to effectively utilize the space in the indoor unit 22.

[0113] In some embodiments, referring to Figure 9, the first air guide housing 110 is provided with a connection structure 116, and the connection structure 116 is adapted to detachably connect the filter net 117. Exemplarily, for example, the connection structure 116 can be a snap connection structure, such that the filter net 117 can be snap-connected to the connection structure 116. Or, the connection structure 116 can be a magnetic attraction structure, such that the filter net 117 can be magnetically connected to the connection structure 116. Or, the connection structure 116 can be a pasting structure, such that the filter net 117 can be pasted to the connection structure 116. Specifically, in this embodiment, by providing the filter net 117 inside the first air guide housing 110, impurities carried in the outdoor air (such as dust and floating flocs in the outdoor air) can be directly filtered out, ensuring the cleanliness of the air flow flowing into the second heat exchange module 300, and further ensuring that the components inside the second heat exchange module 300 are not contaminated, which is beneficial to reducing the number of times of cleaning the components inside the second heat exchange module 300. The filter net 117 is detachably connected to the connection structure 116, which is convenient for regularly cleaning the filter net 117, preventing excessive impurities adsorbed on the filter net 117 from causing blockage of the filter net 117, affecting the air intake volume of the 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] Or, in some embodiments, referring to Figure 10 , the air duct assembly 100 further includes a filter net 117, and the filter net 117 is disposed inside the first air guide housing 110. Exemplarily, for example, the filter net 117 and the first air guide housing 110 can be an integrally formed structure. Or, the filter net 117 can be heat-melt connected inside the first air guide housing 110. Specifically, in this embodiment, the filter net 117 and the first air guide housing 110 adopt a fixed connection structure form, which is beneficial to improving the connection stability of the filter net 117 inside the first air guide housing 110, preventing the filter net 117 from easily falling off from the inside of the first air guide housing 110 during the process of handling and installing the air duct assembly 100, resulting in the loss of the filter net 117, etc.

[0115] Correspondingly, another embodiment of the present invention further provides an air conditioner 10, referring to Figures 11 to 13, the 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 disposed indoors 22 and exchange heat with the air indoors 22 (in other words, the first heat exchange module 200 functions as an indoor unit in the traditional sense). The second heat exchange module 300 is connected to the first heat exchange module 200 and is adapted to be disposed indoors 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 functions as an outdoor unit in the traditional sense. The difference is that the second heat exchange module 300 in this embodiment is disposed indoors 22). The second heat exchange module 300 includes an air inlet 350 and an air outlet 360. The air outlet 360 is adapted to discharge 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 housing 110 in the air duct assembly 100 is connected to the second heat exchange module 300 to be adapted to introduce outdoor air into the air inlet 350. The air conditioner 10 is applicable to the usage scenarios where there is no space for installing the second heat exchange module 300 outdoors. For example, the air conditioner 10 can be installed in a kitchen, or the air conditioner 10 can be installed inside a recreational vehicle or a ship, etc.

[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 circulating flow of the outdoor air in the second heat exchange module 300 to achieve the heat exchange of the second heat exchange module 300. Compared with the second heat exchange module 300 absorbing indoor air for heat exchange, in the solution provided in this embodiment, on the one hand, it can avoid the second heat exchange module 300 absorbing the air that has already undergone heat exchange indoors 22, thereby ensuring the cooling or heating effect indoors 22 and improving the comfort level indoors 22; on the other hand, it can avoid the air pressure indoors 22 decreasing due to the second heat exchange module 300 absorbing the air indoors 22, affecting the normal activities of users indoors 22.

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

[0118] In some embodiments, referring to Figure 13 , the first heat exchange module 200 includes a first shell portion 230 and a first heat exchanger 220, and 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 jointly combined into a third housing 400. The third housing 400 is provided with a third cavity 410, and both the first heat exchanger 220 and the second heat exchanger 320 are disposed within the third cavity 410. The second shell portion 330 is provided with an air inlet 350 and an air outlet 360. In this embodiment, both the first heat exchanger 220 and the second heat exchanger 320 are disposed in the same cavity, which can improve the structural integrity of the air conditioner 10, simplify the manufacturing and assembly processes 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, referring to Figure 15, the second heat exchange module 300 includes a second housing 310 and a second heat exchanger 320. The second housing 310 is provided with a second cavity 340, and the second heat exchanger 320 is disposed in the second cavity 340. The second housing 310 is provided with an air inlet 350 and an air outlet 360 that communicate with the second cavity 340. Both the air inlet 350 and the air outlet 360 are disposed on the same plate body of the second housing 310. Alternatively, the air inlet 350 and the air outlet 360 are respectively disposed on two adjacent or opposite plate bodies of the second housing 310, and the second end portion 112 extends to make 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 disposed on different sides of the second housing 310, by using the second end portion 112, the second port 114 and the air outlet 360 are made to face the same side of the second housing 310. In fact, it is also possible to achieve the intake or exhaust of outdoor air from the same side of the second housing 310 into the second cavity 340 (the flow path of outdoor air into the second cavity 340 is: the second port 114 - the first port 113 - the air inlet 350 - the second cavity 340).

[0121] In some embodiments, the air conditioner 10 is adapted to be at least partially installed in the sandwich space between the ceiling and the ceiling of the kitchen. Specifically, in this embodiment, there is usually a certain accommodating sandwich space between the ceiling and the ceiling of the kitchen. Installing the air conditioner 10 in the above sandwich space is beneficial to making use of the limited space in the kitchen, saving the usable area of the kitchen, and at the same time is beneficial to hiding the air conditioner 10 in the sandwich space to improve the aesthetics of the kitchen.

[0122] See Figure 16, in some embodiments, when the air conditioner 10 is installed in the sandwich space between the suspended ceiling 25 and the ceiling, the suspended ceiling 25 includes a keel support 251 and a plurality of suspended ceiling boards. The keel support 251 includes a plurality of criss-crossed keels 253, and the keels 253 together define a plurality of installation openings 252. Each suspended ceiling board is connected to the keel support 251 and correspondingly covers each installation opening 252. In particular, in this embodiment, the first housing 210 of the first heat exchange module 200 and the second housing 310 of the second heat exchange module 300 are spaced apart. Both the first housing 210 and the second housing 310 are adapted to pass through the installation opening 252, and the gap between the first housing 210 and the second housing 310 is adapted to accommodate the keel 253 of the keel support 251 (that is, a clearance gap 600 is formed between the first housing 210 and the second housing 310, and the clearance gap 600 is adapted to accommodate the keel 253 of the suspended ceiling). In this solution, when installing the air conditioner 10, it is not necessary to cut the keel 253. Two suspended ceiling boards can be directly removed, and the air conditioner can be installed from bottom to top, so that the first housing 210 passes through one of the installation openings 252 and the second housing 310 passes through another adjacent installation opening 252, so that the keel 253 accommodated between the first housing 210 and the second housing 310 can be retained without cutting. Moreover, in this solution, since the connection between the first air guide housing 110 and the second housing 310 is detachable, during actual assembly, if the first air guide housing 110 and the second housing 310 cannot pass through the installation opening 252 as a whole after being connected, the first air guide housing 110 can be detached from the second housing 310 first, and the first air guide housing 110 can be passed through the installation opening 252 upward. Then, the second housing 310 is passed through the installation opening 252 upward, and the first air guide housing 110 and the second housing 310 are connected in the sandwich space between the suspended ceiling 25 and the ceiling, so as to realize the overall installation of the air conditioner 10. This solution also does not require cutting the keel 253, improving the overall structural stability of the suspended ceiling 25.

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

[0124] Specifically, in this embodiment, a downwardly concave avoidance gap 600 is provided at the top of the outer casing of the air conditioner 10. The avoidance gap 600 is used to accommodate the keel bracket 251 for the keel bracket 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. A downwardly concave avoidance gap 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 avoidance gap 600. Preferably, the avoidance gap 600 can be a straight slot to facilitate the assembly between the air conditioner 10 and the keel bracket 251. The avoidance gap 600 can extend from one side of the casing to the other side of the casing, and the avoidance gap 600 penetrates the casing in the horizontal direction. The depth of the avoidance gap 600 can be 80% - 95% of the size of the casing in the vertical direction.

[0125] The following describes the specific dimension settings of the first outer casing 210 in some embodiments. The width dimension of the first outer casing 210 in the transverse direction can be between 260 mm and 265 mm. Exemplarily, the width dimension of the first outer casing 210 in the transverse direction can be 260 mm, 262 mm, 264 mm or 265 mm, etc. The dimension of the first outer casing 210 in the transverse direction in this solution is smaller than the size of the installation opening 252, which facilitates the installation and disassembly of the first heat exchange module 200. In some other embodiments, the width dimension of the first outer casing 210 in the transverse direction can be between 265 mm and 300 mm. Exemplarily, the width dimension of the first outer casing 210 in the transverse direction can be 265 mm, 270 mm, 285 mm, 290 mm or 300 mm, etc. The dimension of the first outer casing 210 in the transverse direction in this solution is larger than the size of the installation opening 252, that is, the first heat exchange module 200 can be set to a larger volume, which can enhance the heat exchange effect of the air conditioner 10. It should be noted that when the dimension of the first outer casing 210 in the transverse direction is larger than the size of the installation opening 252 and installing the first heat exchange module 200, the first outer casing 210 can be tilted diagonally in the transverse direction first, so that the higher end of the first outer casing 210 in the transverse direction passes through the installation opening 252 first, then the first outer casing 210 is pushed forward in the transverse direction, and then the lower end of the first outer casing 210 in the transverse direction passes through the installation 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 length dimension of the first housing 210 in the transverse direction may be between 500 mm and 600 mm. Exemplarily, the length dimension of the first housing 210 in the transverse direction may be 500 mm, 510 mm, 525 mm, 548 mm, 570 mm, 583 mm, 596 mm or 600 mm, etc. The length dimension of the first housing 210 in the transverse direction of this solution is smaller than the size of the installation opening 252, which facilitates the installation and disassembly of the first heat exchange module 200. In other embodiments, the width dimension of the first housing 210 in the transverse direction may be between 600 mm and 631 mm. Exemplarily, the width dimension of the first housing 210 in the transverse direction may be 600 mm, 605 mm, 614 mm, 620 mm, 625 mm or 631 mm, etc. The length dimension of the first housing 210 in the transverse direction of this solution is larger than the size of the installation opening 252, that is, the first heat exchange module 200 can be set to a larger volume, which can enhance the heat exchange effect of the air conditioner 10. It should be noted that when the length dimension of the first housing 210 in the transverse direction is larger than the size of the installation opening 252 and installing the first heat exchange module 200, the first housing 210 can be tilted in the transverse direction first, so that the higher end of the first housing 210 in the transverse direction first penetrates the installation opening 252, then the first housing 210 is pushed forward in the transverse direction, and then the lower end of the first housing 210 in the transverse direction penetrates the installation opening 252, so that the first heat exchange module 200 is installed between the ceiling and the suspended ceiling 25.

[0127] The following introduces the specific dimension settings of the second housing 310 in some embodiments. The width dimension of the second housing 310 in the transverse direction may be between 260 mm and 265 mm. Exemplarily, the width dimension of the second housing 310 in the transverse direction may be 260 mm, 262 mm, 264 mm or 265 mm, etc. The transverse dimension of the second housing 310 in this solution is smaller than the size of the installation opening 252, which facilitates the installation and disassembly of the second heat exchange module 300.
