[0050] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0051] The following is for reference. Figures 1-16 Description of branch box 101 according to an embodiment of the present utility model.

[0052] Reference Figures 1-3 According to a first aspect of the present invention, the branch box 101 includes: a mounting box body 20, a branch assembly 30, and a hub assembly 43.

[0053] The diversion assembly 30 is disposed within the mounting box 20 and is used to connect the liquid refrigerant pipeline of the outdoor unit 10 to the liquid refrigerant pipeline of the indoor unit 11. The mounting box 20 is equipped with the diversion assembly 30 for connecting the liquid refrigerant pipeline of the outdoor unit 10 and the liquid refrigerant pipeline of the indoor unit 11. This allows for the connection between the liquid refrigerant pipelines of the outdoor unit 10 and the indoor unit 11, concentrating at least some of the pipeline connection points between the indoor unit 11 and the outdoor unit 10 within the diversion box 101. This allows for centralized maintenance or installation of the pipeline connection points within the diversion box 101, improving the efficiency of pipeline installation and maintenance.

[0054] The refrigerant distribution assembly 30 includes a first refrigerant distribution component 31, which connects the liquid refrigerant lines of the outdoor unit 10 and the indoor unit 11. The first refrigerant distribution component 31 is used to distribute refrigerant to multiple indoor heat exchangers or to collect refrigerant flowing out of multiple indoor heat exchangers. For example, when the air conditioning system 100 is in cooling mode, the refrigerant discharged from the outdoor unit 10 flows into the first refrigerant distribution component 31, which distributes the refrigerant and allows it to flow into multiple indoor units 11. When the air conditioning system is in heating mode, the refrigerant discharged from the indoor units 11 flows into the first refrigerant distribution component 31 and is collected there. The collected refrigerant then flows into the outdoor unit 10 after leaving the first refrigerant distribution component 31.

[0055] For example, when the air conditioning system 100 is cooling, the compressor discharges the compressed refrigerant through the compressor's exhaust port and flows into the outdoor heat exchanger of the outdoor unit 10. The refrigerant flowing through the outdoor heat exchanger flows into the first distribution component 31, and the refrigerant flowing into the first distribution component 31 flows into the indoor heat exchangers of multiple indoor units 11. For example, when the air conditioning system 100 is heating, the refrigerant flowing through the multiple indoor heat exchangers flows into the first distribution component 31 for collection. The refrigerant flowing through the first distribution component 31 flows into the outdoor heat exchanger of the outdoor unit 10, and the refrigerant flowing through the outdoor heat exchanger flows into the compressor through the compressor's return port to be compressed again.

[0056] The first diversion component 31 includes a throttling component 34, at least a portion of which is integrated into the branch box 101. Compared to placing the throttling component 34 inside the indoor unit 11 or the outdoor unit 10, this makes maintenance of the throttling component 34 more convenient. Furthermore, the branch box 101 can be installed in a suitable location as needed, making the installation location of the throttling component 34 more flexible. For example, the branch box 101 can be installed in a noise-insensitive area, such as the living room or balcony area, reducing the impact of noise generated by the throttling component 34 on users.

[0057] Among them, the throttling component 34 can be an electronic expansion valve.

[0058] The junction box assembly 43 is located within the mounting box 20 and is used to connect the outdoor unit electrical control box of the outdoor unit 10 and the indoor unit electrical control box of the indoor unit 11, thereby enabling electrical connection between the indoor unit 11 and the outdoor unit 10. For example, the junction box assembly 43 can be used to connect the outdoor unit communication line and the indoor unit communication line, thereby concentrating the communication line connection points of the indoor unit 11 and the outdoor unit 10 within the junction box assembly 43. As another example, the junction box assembly 43 can be used to connect the power cord of the outdoor unit 10 and the power cord of the indoor unit 11, thereby concentrating the power cord connection points of the indoor unit 11 and the outdoor unit 10 within the junction box assembly 43, achieving integrated connection and on / off control of the power cords. When the branch box 101 includes the junction box assembly 43, the wiring connection points between the indoor unit 11 and the outdoor unit 10 can be concentrated within the branch box 101, allowing maintenance or installation of the wiring connection points to be carried out within the branch box 101, improving the efficiency of wiring installation and maintenance.

[0059] For example, the junction box assembly 43 can be used to connect the outdoor unit communication line and the indoor unit communication line to achieve integrated connection of the communication lines. The junction box assembly 43 can also be used to connect the outdoor unit power line and the indoor unit power line to the power supply to achieve integrated connection and on / off control of the power lines.

[0060] By including the splitter assembly 30 and the junction box assembly 43 in the branch box 101, and by housing both the splitter assembly 30 and the junction box assembly 43 within the mounting box 20, the splitter assembly 30 and the junction box assembly 43 can be integrated within the branch box 101. When relevant personnel perform maintenance on the splitter assembly 30 or the junction box assembly 43, the construction, inspection, and maintenance of the pipe connection points or line connection points between the indoor unit 11 and the outdoor unit 10 can be carried out centrally within the branch box 101, thereby improving the efficiency of installation or maintenance.

[0061] Furthermore, by concentrating at least some of the pipe connection points and at least some of the wiring connection points between the outdoor unit 10 and the indoor unit 11 within the branch box 101, compared to the related art where the connection harness between the indoor unit 11 and the outdoor unit 10 requires separate wall-penetrating wiring, the wiring of the connection harness between the indoor unit 11 and the outdoor unit 10 can be arranged together with the connection pipes between the outdoor unit 10 and the indoor unit 11. For example, the pipes and harnesses connected to the same indoor unit 11 can pass through the wall together, thus eliminating the need to set up additional holes in the wall for the harness to pass through, reducing construction difficulty and construction time.

[0062] According to the embodiment of the present invention, the branch box 101 includes a shunt assembly 30 and a junction box assembly 43, and both the shunt assembly 30 and the junction box assembly 43 are located within the mounting box 20. This allows the connection points of the lines and pipes between the indoor unit 11 and the outdoor unit 10 to be concentrated within the branch box 101, thus improving the efficiency of line and pipe installation and maintenance. Furthermore, the throttling component 34 is integrated within the branch box 101, which makes maintenance of the throttling component 34 more convenient compared to placing it within the indoor unit 11 or the outdoor unit 10. Additionally, the branch box 101 can be installed in a suitable location as needed, making the installation location of the throttling component 34 more flexible. For example, the branch box 101 can be installed in a noise-insensitive area, reducing the impact of noise generated by the throttling component 34 on the user.

[0063] According to some embodiments of this utility model, refer to Figure 2 , Figure 3 as well as Figure 7 The junction box assembly 43 includes a junction box assembly 44, which includes a communication component 45. The communication component 45 is used to connect the indoor unit communication line and the outdoor unit communication line. By including the communication component 45 in the junction box assembly 44 and connecting the indoor unit communication line and the outdoor unit communication line with the communication component 45, the connection points of the indoor unit communication line and the outdoor unit communication line can be integrated within the junction box assembly 43. This allows relevant personnel to perform construction, inspection, and maintenance centrally within the junction box assembly 43, improving the efficiency of installation and maintenance.

[0064] According to some embodiments of this utility model, refer to Figure 2 , Figure 3 as well as Figure 7 The junction box assembly 43 includes a junction box assembly 44, which in turn includes a power cord assembly 46. The power cord assembly 46 is used to connect the indoor unit power cord and the outdoor unit power cord. By including the power cord assembly 46 in the junction box assembly 44 and connecting the indoor unit power cord and the outdoor unit power cord with the power cord assembly 46, the indoor unit power cord and the outdoor unit power cord can be integrated into the junction box assembly 43. This allows relevant personnel to perform construction, inspection, and maintenance centrally within the junction box assembly 43.

[0065] According to some embodiments of this utility model, refer to Figures 1-5 The first diversion component 31 includes a first main pipe 32 and multiple first branch pipes 33. All first branch pipes 33 are connected to and communicate with the first main pipe 32. The first main pipe 32 is used to connect to the liquid refrigerant pipeline of the outdoor unit 10, and the multiple first branch pipes 33 are respectively used to connect to the liquid refrigerant pipelines of multiple indoor units 11. By including the first main pipe 32 and multiple first branch pipes 33 in the first diversion component 31, and by using the first main pipe 32 to connect to the liquid refrigerant pipeline of the outdoor unit 10, and the multiple first branch pipes 33 to connect to the liquid refrigerant pipelines of multiple indoor units 11, the first diversion component 31 can conveniently combine or divert the flowing refrigerant. For example, when the air conditioning system 100 is cooling, the refrigerant flowing through the outdoor unit 10 flows into the first main pipe 32 of the first diversion component 31, and the refrigerant flowing into the first main pipe 32 is diverted to the multiple first branch pipes 33, which then flow into the multiple indoor units 11. For example, when the air conditioning system 100 is heating, the refrigerant flowing through multiple indoor units 11 flows into the first branch pipe 33 of the first branch component 31, and the refrigerant flowing through multiple first branch pipes 33 flows into the first main pipe 32 for convergence and then flows into the outdoor unit 10.

[0066] For example, when the air conditioning system 100 is cooling, the refrigerant flowing out of the outdoor heat exchanger of the outdoor unit 10 flows into the first main pipe 32 of the first branch component 31. The refrigerant flowing into the first main pipe 32 is distributed to multiple first branch pipes 33 and flows into the indoor heat exchangers of multiple indoor units 11 through the multiple first branch pipes 33 respectively. When the air conditioning system 100 is heating, the refrigerant discharged from the indoor heat exchangers of multiple indoor units 11 flows into the first branch pipes 33 of the first branch component 31. The refrigerant flowing through the multiple first branch pipes 33 flows into the first main pipe 32 for convergence and finally flows into the outdoor heat exchanger of the outdoor unit 10.

[0067] At least a portion of the first branch pipe 33 is provided with a throttling device 34. By providing a throttling device 34 on at least a portion of the first branch pipe 33, the throttling device 34 can individually adjust the refrigerant flow path in the indoor unit 11 connected to the first branch pipe 33, thus enabling more precise control of the refrigerant flow path of a single indoor unit 11.

[0068] The fact that at least some of the first branch pipes 33 are equipped with throttling components 34 may include the following situations: for example, each of the first branch pipes 33 is equipped with a throttling component 34; or, some of the first branch pipes 33 are equipped with throttling components 34, and the indoor unit 11 corresponding to another part of the first branch pipes 33 is equipped with a throttling component 34. In this way, the number and position of the throttling components 34 in the branch box 101 can be adjusted as needed.

[0069] According to some embodiments of this utility model, refer to Figures 1-5 A portion of the first branch pipe 33 is equipped with a throttling device 34. By equipping a portion of the first branch pipe 33 with a throttling device 34, the branch box 101 can be made more compatible. For example, the first branch pipe 33 with the throttling device 34 can be connected to an indoor unit 11 that does not have a throttling device 34; the first branch pipe 33 without the throttling device 34 can be connected to an indoor unit 11 that has a throttling device 34 inside.

[0070] Furthermore, the number of first branch pipes 33 can be increased. For example, the total number of first branch pipes 33 in the branch box 101 can be greater than the number of indoor units 11, or the total number of first branch pipes 33 equipped with throttling components 34 can be no less than the number of indoor units 11. Connections can be made as needed. For example, when none of the indoor units 11 connected to the branch box 101 are equipped with throttling components 34, each indoor unit 11 can be connected to the first branch pipe 33 of the branch box 101 equipped with a diversion component. When some indoor units 11 connected to the branch box 101 are equipped with throttling components 34 and others are not, the indoor units 11 without throttling components 34 can be connected to the first branch pipe 33 of the branch box 101 equipped with a diversion component, and the indoor units 11 equipped with throttling components 34 can be connected to the first branch pipe 33 of the branch box 101 without throttling components 34.

[0071] According to some embodiments of this utility model, the specifications of the throttling components 34 provided on at least some of the first branch pipes 33 are different. For example, the specifications of the throttling components 34 provided on some of the first branch pipes 33 may be different, or the specifications of the throttling components 34 provided on each of the first branch pipes 33 may be different. By making the specifications of the throttling components 34 provided on at least some of the first branch pipes 33 different, the throttling components 34 can meet the needs of different indoor units 11. For indoor units 11 of different capacities, different models of throttling components 34 can be configured on the first branch pipes 33 connected to the indoor units 11, so that the throttling and pressure reduction capacity of the throttling components 34 corresponds to the needs of the indoor units 11. In this way, different first branch pipes 33 can be connected to indoor units 11 of different capacities, increasing the versatility of the branch box 101.

[0072] Of course, in other embodiments, the specifications of the throttling component 34 provided on each first branch pipe 33 can also be the same.

[0073] According to some embodiments of this utility model, refer to Figures 2-5 The first branch pipe 33 has a first connector 35, which is used to connect to the liquid refrigerant pipeline of the indoor unit 11. At least some of the first branch pipes 33 have different specifications for their first connectors 35. For example, some of the first branch pipes 33 may have different specifications for their first connectors 35, or each first branch pipe 33 may have a different specification for its first connector 35. By making the specifications of the first connectors 35 of at least some of the first branch pipes 33 different, the first branch pipes 33 can meet the connection requirements of different indoor units 11. For indoor units 11 with different connector models, the first connectors 35 on the first branch pipes 33 can be matched with indoor units 11 with different connector models, so that the branch box 101 can be connected to indoor units 11 with multiple pipeline connector models, increasing the versatility of the branch box 101.

[0074] Of course, in other embodiments, the specifications of the first connector 35 of each first branch pipe 33 may also be the same.

[0075] According to some embodiments of this utility model, refer to Figures 2-5 The diversion assembly 30 includes a second diversion component 40, which is used to connect the gaseous refrigerant pipeline of the outdoor unit 10 and the gaseous refrigerant pipeline of the indoor unit 11. The second diversion component 40 is located above the first diversion component 31, which can make full use of the vertical space inside the mounting box 20, making the overall layout of the diversion assembly 30 more compact.

[0076] For example, when the air conditioning system 100 is cooling, the refrigerant flowing through multiple indoor heat exchangers flows into the second distribution component 40 for collection. The refrigerant flowing through the second distribution component 40 then flows into the compressor through the compressor's return port and is compressed again. When the air conditioning system 100 is heating, the compressor discharges the compressed refrigerant through the compressor's exhaust port, which then flows into the second distribution component 40. The refrigerant flowing into the second distribution component 40 then flows into the indoor heat exchangers of multiple indoor units 11.

[0077] For example, when the air conditioning system 100 is cooling, the compressor discharges the compressed refrigerant through the compressor's exhaust port and flows into the outdoor heat exchanger of the outdoor unit 10. The refrigerant flowing through the outdoor heat exchanger flows into the first distribution component 31. The refrigerant flowing into the first distribution component 31 flows into the indoor heat exchangers of multiple indoor units 11. The refrigerant flowing through the multiple indoor heat exchangers flows into the second distribution component 40 for collection. The refrigerant flowing through the second distribution component 40 flows into the compressor through the compressor's return port and is compressed again.

[0078] For example, when the air conditioning system 100 is heating, the compressor discharges the compressed refrigerant through the compressor's exhaust port and flows into the second distribution component 40. The refrigerant flowing into the second distribution component 40 flows into the indoor heat exchangers of multiple indoor units 11. The refrigerant flowing through the multiple indoor heat exchangers flows into the first distribution component 31 for collection. The refrigerant flowing through the first distribution component 31 flows into the outdoor heat exchanger of the outdoor unit 10. The refrigerant flowing through the outdoor heat exchanger flows into the compressor through the compressor's return port and is compressed again.

[0079] According to some embodiments of this utility model, refer to Figures 2-5 The second diversion component 40 includes a second main pipe 41 and a plurality of second branch pipes 42. The plurality of second branch pipes 42 are all connected to and communicate with the second main pipe 41. The second main pipe 41 is used to connect to the gaseous refrigerant pipeline of the outdoor unit 10, and the plurality of second branch pipes 42 are respectively used to connect to the gaseous refrigerant pipelines of the plurality of indoor units 11. By including a second main pipe 41 and multiple second branch pipes 42 in the second diversion component 40, and by connecting the second main pipe 41 to the gaseous refrigerant pipeline of the outdoor unit 10, and connecting the multiple second branch pipes 42 to the gaseous refrigerant pipelines of the multiple indoor units 11, the second diversion component 40 facilitates the convergence or diversion of the incoming refrigerant. For example, when the air conditioning system 100 is cooling, the refrigerant flowing out of the multiple indoor units 11 flows into the second branch pipes 42 of the second diversion component 40, and the refrigerant flowing through the multiple second branch pipes 42 flows into the second main pipe 41 for convergence before flowing into the outdoor unit 10; when the air conditioning system 100 is heating, the refrigerant discharged from the outdoor unit 10 flows into the second main pipe 41 of the second diversion component 40, and the refrigerant flowing through the second main pipe 41 is diverted to the multiple second branch pipes 42, and flows into the multiple indoor units 11 through the multiple second branch pipes 42 respectively.

[0080] For example, when the air conditioning system 100 is cooling, the compressor discharges the compressed refrigerant through the compressor's exhaust port and flows into the outdoor heat exchanger of the outdoor unit 11. The refrigerant flowing through the outdoor heat exchanger flows into the first distribution component 70. The refrigerant flowing into the first distribution component 70 first flows into the first main pipe 71. The refrigerant flowing into the first main pipe 71 is distributed into multiple first branch pipes 72. The refrigerant flowing out of the multiple first branch pipes 72 flows into multiple indoor heat exchangers of the indoor units 10 respectively. The refrigerant flowing through the multiple indoor heat exchangers flows into multiple second branch pipes 82 of the second distribution component 80 respectively. The refrigerant flowing out of the multiple second branch pipes 82 is collected into the second main pipe 82. The refrigerant flowing through the second main pipe 82 flows into the compressor through the compressor's return port and is compressed again.

[0081] For example, when the air conditioning system 100 is heating, the compressor discharges the compressed refrigerant through the compressor's exhaust port and flows into the second main pipe 81 of the second distribution component 80. The refrigerant flowing into the second main pipe 81 is distributed to multiple second branch pipes 82. The refrigerant flowing out of the multiple second branch pipes 82 flows into the indoor heat exchangers of multiple indoor units 10 respectively. The refrigerant flowing through the multiple indoor heat exchangers flows into the multiple first branch pipes 72 of the first distribution component 70 respectively. The refrigerant flowing out of the multiple first branch pipes 72 is collected into the first main pipe 71. The refrigerant flowing through the first main pipe 71 flows into the outdoor heat exchanger of the outdoor unit 11. The refrigerant flowing through the outdoor heat exchanger flows into the compressor through the compressor's return port and is compressed again.

[0082] According to some embodiments of this utility model, refer to Figures 2-5 The second branch pipe 42 has a second connector 421, which is used to connect to the gaseous refrigerant pipeline of the indoor unit 11. At least some of the second connectors 421 of the second branch pipe 42 have different specifications. For example, the specifications of the second connectors 421 of some of the second branch pipes 42 may be different, or the specifications of the second connectors 421 of each second branch pipe 42 may be different. By making the specifications of the second connectors 421 of at least some of the second branch pipes 42 different, the second branch pipe 42 can meet the connection requirements of different indoor units 11. For indoor units 11 with different connector models, the second connectors 421 on the second branch pipe 42 can be matched with indoor units 11 with different connector models, so that the branch box 101 can be connected to indoor units 11 with multiple pipeline connector models, increasing the versatility of the branch box 101.

[0083] Of course, in other embodiments, the specifications of the second connector 421 of each second branch pipe 42 may also be the same.

[0084] According to some embodiments of this utility model, refer to Figures 2-5The first main pipe 32 and the second main pipe 41 exit from the same side of the mounting box 20. For example, the mounting box 20 is provided with a first main outlet hole and a second main outlet hole. The first main outlet hole can be used for the first main pipe 32 to exit, and the second main outlet hole can be used for the second main pipe 41 to exit. The first main outlet hole and the second main outlet hole can be located on the same side of the mounting box 20. Since both the first main pipe 32 and the second main pipe 41 need to be connected to the outdoor unit 10, by making the outlet direction and arrangement position of the first main pipe 32 and the second main pipe 41 closer, it is easier for the first main pipe 32 and the second main pipe 41 to be connected to the outdoor unit 10.

[0085] The first branch pipe 33 and the second branch pipe 42 exit from the same side of the mounting box 20. For example, the mounting box 20 can be provided with a first branch pipe hole and a second branch pipe hole. The first branch pipe hole can be used for the exit of the first branch pipe 33, and the second branch pipe hole can be used for the exit of the second branch pipe 42. The first branch pipe hole and the second branch pipe hole can be located on the same side of the mounting box 20. Since both the first branch pipe 33 and the second branch pipe 42 need to be connected to the indoor unit 11, by making the exit direction and arrangement position of the first branch pipe 33 and the second branch pipe 42 closer, it is easier to connect the first branch pipe 33 and the second branch pipe 42 to the indoor unit 11.

[0086] The first main pipe 32 and the first branch pipe 33 exit from different sides of the mounting box 20. Since the first main pipe 32 is connected to the outdoor unit 10 and the first branch pipe 33 is connected to the indoor unit 11, the different exit directions of the first main pipe 32 and the first branch pipe 33 facilitate the exit of the first main pipe 32 and the first branch pipe 33, and reduce pipe interference when connected to the outdoor unit 10 and the indoor unit 11 respectively.

[0087] According to some embodiments of this utility model, refer to Figures 2-5 The outlet direction of the first main pipe 32 is parallel to the outlet direction of the second main pipe 41. By making the outlet direction of the first main pipe 32 parallel to the outlet direction of the second main pipe 41, it is easier to arrange the first main pipe 32 and the second main pipe 41, making the installation of the first main pipe 32 and the second main pipe 41 more convenient, and it is also conducive to achieving a compact arrangement of the first main pipe 32 and the second main pipe 41.

[0088] According to some embodiments of this utility model, refer to Figures 2-5 The outlet direction of the first branch pipe 33 is parallel to the outlet direction of the second branch pipe 42. By making the outlet direction of the first branch pipe 33 parallel to the outlet direction of the second branch pipe 42, it is easier to arrange the first branch pipe 33 and the second branch pipe 42, and to make the installation of the first branch pipe 33 and the second branch pipe 42 more convenient.

[0089] According to some embodiments of this utility model, refer to Figures 8-13The first main pipe 32 and the first branch pipe 33 exit from adjacent sides of the mounting box 20. By having the first main pipe 32 and the first branch pipe 33 exit from adjacent sides of the mounting box 20, it is convenient to connect the first main pipe 32 to multiple first branch pipes 33, to connect the first main pipe 32 to the outdoor unit 10, and to connect the first branch pipe 33 to the indoor unit 11. For example, the first main pipe 32 can extend along a first direction, which can be the length direction of the mounting box 20; the first branch pipe 33 can extend along a second direction, which can be the width direction of the mounting box 20; multiple first branch pipes 33 are arranged along the first direction, and each first branch pipe 33 is connected to the first main pipe 32.

[0090] According to some embodiments of this utility model, refer to Figures 8-13 The outlet direction of the first main pipe 32 intersects with the outlet direction of the first branch pipe 33. This intersection facilitates the connection of the first main pipe 32 to multiple first branch pipes 33, the connection of the first main pipe 32 to the outdoor unit 10, and the connection of the first branch pipes 33 to the indoor unit 11. For example, the first main pipe 32 can extend along a first direction, which can be the length direction of the mounting box 20; the first branch pipes 33 can extend along a second direction, which can be the width direction of the mounting box 20; multiple first branch pipes 33 are arranged along the first direction, and each first branch pipe 33 is connected to the first main pipe 32.

[0091] According to some embodiments of this utility model, the first main pipe 32 and the second main pipe 41 exit in the same direction, and multiple first branch pipes 33 and multiple second branch pipes 42 exit in the same direction. The exit directions of the first main pipe 32 and the first branch pipes 33 intersect, and the exit directions of the second main pipe 41 and the second branch pipes 42 intersect. By making the first main pipe 32 and the second main pipe 41 exit in the same direction, it is convenient for the first main pipe 32 and the second main pipe 41 to be connected to the outdoor unit 10; by making multiple first branch pipes 33 and multiple second branch pipes 42 exit in the same direction, it is convenient for the first branch pipes 33 and the second branch pipes 42 to be connected to the indoor unit 11. The outdoor unit 10 and the indoor unit 11 are usually located in different positions. By making the exit directions of the first main pipe 32 and the first branch pipe 33 intersect, and the exit directions of the second main pipe 41 and the second branch pipe 42 intersect, it is convenient for the main pipe to exit and connect to the outdoor unit 10, and it is also convenient for the branch pipes to exit and connect to the indoor unit 11.

[0092] According to some embodiments of this utility model, refer to Figures 8-13The outer surface of the mounting box 20 includes a mounting surface 21 facing the mounting base 50. The outlet directions of the first main pipe 32 and / or the first branch pipe 33 are parallel to the mounting surface 21. For example, the outlet direction of the first main pipe 32 may be parallel to the mounting surface 21, or the outlet direction of the first branch pipe 33 may be parallel to the mounting surface 21, or both the outlet directions of the first main pipe 32 and the first branch pipe 33 may be parallel to the mounting surface 21. When the branch box 101 is installed onto the mounting base 50, the mounting surface 21 of the branch box 101 can face and contact the mounting base 50. By making the outlet directions of the first main pipe 32 and / or the first branch pipe 33 parallel to the mounting surface 21, it is convenient to install and fix the branch box 101 onto the mounting base 50, reducing interference between the first main pipe 32 and / or the first branch pipe 33 and the mounting base 50 during installation. In addition, when adjusting the outlet direction of the first main pipe 32 or the first branch pipe 33, the mounting surface 21 of the branch box 101 can be rotated in a plane parallel to the mounting surface 21 without changing the angle. This allows the outlet direction of the first main pipe 32 or the first branch pipe 33 to be adjusted to a suitable position, so that the branch box 101 can be connected to the outdoor unit 10 or the indoor unit 11. In this way, the needs of the construction scenario can be met by adjusting the outlet direction of the first main pipe 32 or the first branch pipe 33.

[0093] The mounting base 50 may include walls, floors, ceilings, etc. The branch box 101 can be directly connected to the mounting base 50, or the branch box 101 can be installed and fixed to the mounting base 50 by a mounting bracket.

[0094] According to some embodiments of this utility model, the outer surface of the mounting box 20 includes a mounting surface 21 facing the mounting base 50, and the outlet directions of the first main pipe 32 and / or the first branch pipe 33 intersect with the mounting surface 21. For example, the outlet direction of the first main pipe 32 may intersect with the mounting surface 21, or the outlet direction of the first branch pipe 33 may intersect with the mounting surface 21, or both the outlet directions of the first main pipe 32 and the first branch pipe 33 may intersect with the mounting surface 21. By making the outlet directions of the first main pipe 32 and / or the first branch pipe 33 intersect with the mounting surface 21, when adjusting the outlet direction of the first main pipe 32 or the first branch pipe 33, the mounting surface 21 of the branch box 101 can be rotated in a plane perpendicular to the mounting surface 21 without changing the angle, so as to facilitate the connection of the branch box 101 with the outdoor unit 10 or the indoor unit 11. In this way, the needs of the construction scenario can be met by adjusting the outlet direction of the first main pipe 32 or the first branch pipe 33.

[0095] It should be noted that during the installation of the branch box 101, the outlet pipe direction of the branch box 101 can be adjusted by rotating the branch box 101, so that the coil of the throttling component 34 faces upward. When the coil of the throttling component 34 faces upward, the risk of the coil of the throttling component 34 detaching can be reduced.

[0096] In addition, when connecting the indoor unit 11 or outdoor unit 10 to the branch box 101, rotating the branch box 101 to adjust the direction of the outlet pipe still cannot meet the specific construction scenario. A transition pipe can be set to meet the needs of more construction scenarios. For example, the transition pipe can be an L-shaped transition pipe.

[0097] According to some embodiments of this utility model, refer to Figures 2-5 The outer surface of the mounting box 20 includes a mounting surface 21 for facing the mounting base 50. The mounting box 20 includes a box body 22 and a box top cover 27. The box body 22 includes a bottom box 23, a first side plate 24, a second side plate 25, and a third side plate 26. The bottom box 23 has a mounting surface 21. The first side plate 24, the second side plate 25, and the third side plate 26 are detachably mounted on the bottom box 23 and located on different sides of the bottom box 23. The first side plate 24 and the third side plate 26 are arranged opposite to each other. The first main pipe 32 exits from the first side plate 24, and the first branch pipe 33 exits from the second side plate 25. The first side plate 24 and the third side plate 26 are interchangeable. By making the box body 22 include a bottom box 23, a first side plate 24, a second side plate 25, and a third side plate 26, and the bottom box 23 has a mounting surface 21, and the first side plate 24, the second side plate 25, and the third side plate 26 are all detachably provided on the bottom box 23 and located on different sides of the bottom box 23, it is easier to assemble and connect the mounting box body 20, and it is easier to connect the mounting box body 20 with the first pipeline and the first branch.

[0098] By having the first main pipe 32 exit from the first side plate 24 and the first branch pipe 33 exit from the second side plate 25, and by allowing the first side plate 24 and the third side plate 26 to be interchanged, the exit direction of the first main pipe 32 can be changed without changing the installation position or installation angle of the mounting box 20, and without changing the exit direction of the first branch pipe 33, so that the branch box 101 can meet the needs of more construction scenarios.

[0099] For example, in a construction scenario where the first main pipe 32 needs to exit from the left side of the branch box 101 and the first branch pipe 33 needs to exit from the front side of the branch box 101, the first side plate 24 can be located on the left side of the branch box 101, and the third side plate 26 can be located on the right side of the branch box 101. When a construction scenario requires the first main pipe 32 to exit from the right side of the branch box 101 and the first branch pipe 33 to exit from the front side of the branch box 101, and it is not desired to change the exit direction of the first branch pipe 33, the first side plate 24 and the third side plate 26 can be removed. The first side plate 24 can be installed on the right side of the mounting box 20, and the third side plate 26 can be installed on the left side of the mounting box 20, so that the first main pipe 32 can exit from the right side of the branch box 101.

[0100] According to some embodiments of this utility model, refer to Figures 2-5 The outer wall of the mounting box 20 is provided with mounting ears 28 for mounting and fixing the branch box 101. By providing mounting ears 28 on the outer wall of the mounting box 20 for mounting and fixing the branch box 101, the branch box 101 can be easily mounted and fixed to the mounting base 50.

[0101] For example, refer to Figure 14 The mounting base 50 is the ceiling, and the branch box 101 is installed and fixed on the ceiling. The branch box 101 is installed and fixed on the mounting base 50 by means of suspension.

[0102] For example, refer to Figure 15 When the mounting base 50 is a wall, the mounting base 50 is equipped with hooks, and the mounting ears 28 are hung on the hooks. The branch box 101 is installed on the mounting base 50 using a wall-mounted installation method.

[0103] For example, refer to Figure 16 When the installation base 50 is the ground, a pad can be placed on the ground, and the branch box 101 can be placed on the pad.

[0104] According to some embodiments of this utility model, the mounting ear 28 is detachably connected to the mounting box 20, for example, the mounting ear 28 and the mounting box 20 are connected by fasteners. Since the mounting ear 28 is detachable, the branch box 101 can be installed and fixed in different positions by adjusting the position of the mounting ear 28, so that the branch box 101 can adapt to different installation scenarios.

[0105] According to some embodiments of this utility model, refer to Figures 2-5 There are multiple mounting ears 28, which are located on different sides of the mounting box 20. By having multiple mounting ears 28 located on different sides of the mounting box 20, some of the mounting ears 28 can be selected for installation and fixation according to the needs of the installation orientation or installation scenario, so that the branch box 101 can be set up and installed in different installation scenarios to adapt to different installation scenarios.

[0106] An air conditioning system 100 according to a second aspect embodiment of the present invention includes: an outdoor unit 10, at least one indoor unit 11, and at least one branch box 101. The branch box 101 is the same as the branch box 101 according to a first aspect embodiment of the present invention, and at least some of the indoor units 11 are connected to the outdoor unit 10 through the branch box 101. For example, the indoor unit 11 includes a connector, and pipes are connected to the connector.

[0107] For example, there can be one outdoor unit 10 and multiple indoor units 11.

[0108] For example, an air conditioning system 100 includes an outdoor unit 10, multiple indoor units 11, and a branch box 101, through which the outdoor unit 10 is connected to all the indoor units 11.

[0109] For example, the air conditioning system 100 includes an outdoor unit 10, multiple indoor units 11, and a branch box 101. Some of the indoor units 11 are connected to the outdoor unit 10 through the branch box 101, and some of the indoor units 11 are connected to the outdoor unit 10 through branch pipes. This makes the branch box 101 compatible with branch pipes, and the branch box 101 has wider applicability.

[0110] For example, the air conditioning system 100 includes an outdoor unit 10, five indoor units 11, and a branch box 101. The first branching component 31 includes a first main pipe 32 and four first branch pipes 33. The four indoor units 11 are connected to the outdoor unit 10 through the branch box 101, and one indoor unit 11 is connected to the outdoor unit 10 through a branch pipe. The branch box 101 includes a first branching component 31 and a second branching component 40. The first branching component 31 includes a first main pipe 32 and four first branch pipes 33, and the second branching component 40 includes a second main pipe 41 and four second branch pipes 42. The first main pipe 32 and the second main pipe 41 are both connected to the outdoor unit 10, and the four first branch pipes 33 and the four second branch pipes 42 are all connected to the indoor units 11. The branch pipe includes a first branch pipe 12 and a second branch pipe 13. The main pipe of the first branch pipe 12 is connected to the outdoor unit 10, and one of the two branch pipes of the first branch pipe 12 is connected to the first main pipe 32. The other of the two branch pipes of the second branch pipe 13 is connected to the remaining indoor unit 11. The main pipe of the second branch pipe 13 is connected to the outdoor unit 10, and one of the two branch pipes of the second branch pipe 13 is connected to the second main pipe 41. The other of the two branch pipes of the second branch pipe 13 is connected to the remaining indoor unit 11.

[0111] For example, the air conditioning system 100 includes an outdoor unit 10, a plurality of indoor units 11 and two branch boxes 101. Some of the indoor units 11 are connected to the outdoor unit 10 through one of the branch boxes 101, and other indoor units 11 are connected to the outdoor unit 10 through the other branch box 101.

[0112] For example, the air conditioning system 100 includes an outdoor unit 10, multiple indoor units 11, and two branch boxes 101. Some indoor units 11 are connected to the outdoor unit 10 through one branch box 101, some indoor units 11 are connected to the outdoor unit 10 through the other branch box 101, and some indoor units 11 are connected to the outdoor unit 10 through branch pipes. This makes the branch box 101 compatible with branch pipes, thus broadening its versatility.

[0113] For example, if there are extra first branch pipes 33 or second branch pipes 42 in a single branch box 101, the unused branch pipes can be plugged with copper nut plugs.

[0114] For example, if the number of first branch pipes 33 or second branch pipes 42 in a single branch box 101 is insufficient to match multiple indoor units 11, multiple branch boxes 101 can be enabled to match the number of indoor units 11.

[0115] According to the air conditioning system 100 of this utility model embodiment, by setting the above-mentioned branch box 101, the line connection points and pipe connection points between the indoor unit 11 and the outdoor unit 10 can be concentrated in the branch box 101, and the maintenance or installation of the lines and pipes can be concentrated in the branch box 101, thereby improving the efficiency of line and pipe installation and maintenance; furthermore, by integrating the throttling component 34 into the branch box 101, the installation position of the throttling component 34 can be more flexible, and the noise generated by the throttling component 34 can be reduced to reduce the impact on users.
