Abstract
Description
Technical Field
[0001] This utility model relates to the field of air conditioning technology, and in particular to a bracket structure and a multi-split air conditioning system. Background Technology
[0002] A multi-split air conditioning system is a type of air conditioning system that connects multiple units to a single unit. It comprises four core components: a compressor, a condenser, a throttling device (often an electronic expansion valve in the indoor unit), and an evaporator. Its refrigeration principle involves the compressor adiabatically compressing low-pressure, low-temperature gas into high-temperature, high-pressure gas. This gas then enters the condenser for isobaric condensation, cooling the gaseous refrigerant into a liquid state. The liquid refrigerant is then throttled and depressurized by the expansion valve, resulting in a low-temperature, low-pressure liquid refrigerant. Finally, the evaporator evaporates this liquid refrigerant into a low-temperature, low-pressure pure gaseous refrigerant, which then returns to the compressor for the refrigeration cycle. With increasing energy efficiency requirements, multi-split systems have incorporated auxiliary components such as oil separators and piping into their basic architecture. Especially for top-discharge multi-split systems, the design must not only meet basic cooling and heating functions but also prioritize reliability factors such as oil return and oil equalization.
[0003] In existing technologies, the internal components of top-discharge multi-split air conditioning units are usually arranged using empirical methods, which increases the complexity of system configuration and connecting pipelines, resulting in lower production efficiency. Utility Model Content

[0044] The following is combined Figures 1-8 Describe the support structure of this utility model.
[0045] An embodiment of the first aspect of this utility model provides a support structure, such as... Figures 1 to 3 As shown, the bracket structure includes a chassis 100 and a bracket assembly 200 disposed on the chassis 100. The bracket assembly 200 has a first mounting position 201 and a second mounting position 202 adjacent to the first mounting position 201. The first mounting position 201 is used to install an oil separator 300, and the second mounting position 202 is used to install a solenoid valve 400.
[0046] It is understood that the support structure includes a chassis 100 and a support assembly 200 disposed on the chassis 100. The support assembly 200 has a first mounting position 201 for mounting an oil separator 300 and a second mounting position 202 for mounting a solenoid valve 400, thereby realizing the integrated design of the oil separator 300 and the solenoid valve 400 on the support assembly 200.
[0047] It should be noted that in the prior art, the oil separator 300 and the solenoid valve 400 are each assembled inside the top-discharge multi-split air conditioning unit. Due to the limited internal space of the multi-split air conditioning unit, the installation process of the oil separator 300 and the solenoid valve 400 is time-consuming and labor-intensive, resulting in low production efficiency. This utility model uses a bracket assembly 200 with a first mounting position 201 and a second mounting position 202. The oil separator 300 and the solenoid valve 400 are pre-assembled in the first mounting position 201 and the second mounting position 202 respectively, facilitating the integrated design of the oil separator 300 and the solenoid valve 400 on the bracket assembly 200. The bracket structure integrating the oil separator 300 and the solenoid valve 400 enables rapid assembly inside the multi-split air conditioning unit, thereby improving production efficiency.
[0048] Specifically, such as Figure 1 and Figure 2As shown, the first mounting position 201 and the second mounting position 202 are arranged adjacent to each other, so that the positions of the oil separator 300 and the solenoid valve 400 are fixed and arranged close to each other, realizing a compact integrated design inside the system, effectively simplifying the piping layout inside the multi-split unit and reducing the space occupied inside the multi-split unit.
[0049] It should be noted that the oil separator 300 and the solenoid valve 400 are arranged close to each other, which shortens the connecting pipeline between the oil separator 300 and the solenoid valve 400, reduces the number of bends and pipeline pressure drop, and improves system energy efficiency.
[0050] The bracket structure provided in this embodiment of the utility model, by designing a first mounting position 201 for mounting the oil separator 300 and a second mounting position 202 for mounting the solenoid valve 400 on the bracket assembly 200, realizes the integrated design of the oil separator 300 and the solenoid valve 400 on the bracket assembly 200. The bracket structure integrating the oil separator 300 and the solenoid valve 400 can realize rapid assembly inside the multi-unit air conditioner, thereby improving production efficiency.
[0051] In one embodiment of the present invention, the bracket assembly 200 is detachably connected to the chassis 100, thereby facilitating the separation of the bracket assembly 200 from the chassis 100 for maintenance of the oil separator 300 and the solenoid valve 400 on the bracket assembly 200.
[0052] It should be noted that in other embodiments, the bracket assembly 200 can also be fixedly connected to the chassis 100, such as by welding; the chassis 100 is detachably connected inside the multi-split unit, which facilitates the maintenance of the components (oil separator 300 and solenoid valve 400) on the bracket structure.
[0053] Optionally, the oil separator 300 and the support assembly 200, and the solenoid valve 400 and the support assembly 200 are connected by a quick-release structure, so that the oil separator 300 or the solenoid valve 400 can be inspected and repaired separately through the quick-release structure during maintenance, thereby improving the convenience of maintenance.
[0054] In one embodiment of this utility model, such as Figures 1 to 3 As shown, the bracket assembly 200 includes a mounting bracket 210 and a first connecting beam 220. The mounting bracket 210 is provided with a first mounting position 201, which includes a mounting hole 211 and a first connecting part 212. The mounting hole 211 is used to place the oil separator 300, and the first connecting part 212 is used to connect with the oil separator 300. The first connecting beam 220 is connected to the mounting bracket 210, and the first connecting beam 220 is provided with a second mounting position 202.
[0055] It is understood that the oil separator 300 is arranged in the mounting hole 211 of the mounting bracket 210 and connected to the oil separator 300 through the first connecting part 212, so as to fix the oil separator 300 on the mounting bracket 210; the first connecting beam 220 is connected to the mounting bracket 210, and the solenoid valve 400 is installed in the second mounting position 202 on the first connecting beam 220.
[0056] Optionally, the first connecting part 212 is a first connecting hole opened on the mounting bracket 210, and a positioning plate is connected to the first connecting hole. The positioning plate abuts against the outer side wall of the oil separator 300. For example, the positioning plate can be L-shaped, with one end of the positioning plate connected to the first connecting hole and the other end of the positioning plate abutting against the outer side wall of the oil separator 300.
[0057] It is understood that each mounting bracket 210 has multiple first connecting parts 212 located outside the mounting hole 211, thereby achieving the fixed installation of the oil separator 300 on the mounting bracket 210 through the positioning plates on the multiple first connecting parts 212.
[0058] In this embodiment, each mounting bracket 210 is provided with three first connecting parts 212. The mounting bracket 210 is arranged vertically and has a first side and a second side that are opposite each other in the horizontal direction. Two first connecting parts 212 are located on the first side of the mounting bracket 210, and the remaining first connecting part 212 is located on the second side of the mounting bracket 210 and is located vertically between the two first connecting parts 212 on the first side.
[0059] In one embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the second mounting position 202 includes a plurality of second connecting parts 221 spaced apart on the first connecting beam 220, the second connecting parts 221 being used to connect to the solenoid valve 400.
[0060] Optionally, the second connecting part 221 is a second connecting hole opened on the first connecting beam 220, through which the solenoid valve 400 is fixedly installed on the first connecting beam 220; there can be multiple second connecting parts 221, so that multiple solenoid valves 400 can be installed.
[0061] In this embodiment, four second connecting parts 221 are arranged on the first connecting beam 220. Each second connecting part 221 includes two second connecting holes spaced apart in the horizontal direction. The two second connecting holes can realize the installation of a solenoid valve 400.
[0062] In a preferred embodiment of this utility model, such as Figure 2 and Figure 3As shown, the bracket assembly 200 also includes a second connecting beam 230, which is connected to the mounting bracket 210. The second connecting beam 230 is provided with a first fixing component 240, which is used to fix the first pipeline 500, which is connected to the solenoid valve 400.
[0063] Understandably, the mounting bracket 210 is also connected to a second connecting beam 230, and a first fixing component 240 is arranged on the second connecting beam 230. The first fixing component 240 is used to fix the pipeline connected to the solenoid valve 400, prevent pipeline vibration, significantly reduce the risk of pipeline cracking caused by long-term mechanical fatigue, improve pipeline service life, ensure the sealing reliability of the connection between the solenoid valve 400 and the first pipeline 500, reduce abnormal noise caused by pipeline resonance, reduce system operating noise, and significantly improve user comfort.
[0064] Optional, such as Figures 5 to 8 As shown, the first fixing component 240 includes a fixing clip 241, which is detachably connected to the second connecting beam 230. An installation space for installing the first pipeline 500 is formed between the fixing clip 241 and the second connecting beam 230, thereby enabling the installation and removal of the first pipeline 500 on the second connecting beam 230 through the fixing clip 241.
[0065] Furthermore, the first fixing component 240 also includes a flexible component 242, which is disposed in the installation space and has an assembly hole through which the first pipeline 500 passes, thereby improving the stability of fixing the first pipeline 500.
[0066] For example, the first fixing component 240 includes a fixing clip 241 and a flexible component 242. The fixing clip 241 includes a positioning part and two connecting ears. The positioning part has an arc-shaped cross-section. The two connecting ears are respectively connected to the two ends of the positioning part. The connecting ears are provided with second connecting holes. The second connecting beam 230 is provided with third connecting holes that correspond to the second connecting holes. The flexible component 242 is fixed on the second connecting beam 230 and located in the two third connecting holes. The flexible component 242 has an assembly hole for the first pipeline 500 to pass through. The upper surface of the flexible component 242 is an arc surface that mates with the positioning part. The two second connecting holes of the fixing clip 241 are respectively connected to the two third connecting holes on the second connecting beam 230 to fix the first pipeline 500 on the second connecting beam 230. The flexible component 242 also improves the stability of the first pipeline 500 and reduces the vibration of the first pipeline 500.
[0067] In this embodiment, the flexible component 242 is provided with a tensioning groove, which enables the flexible component 242 to have adjustable elastic deformation capability, adapting to different pipe diameters of the first pipeline, and the tensioning groove can absorb the vibration energy during system operation through controllable deformation, effectively preventing the first pipeline 500 from loosening; the tensioning groove will generate a self-locking effect under the action of pre-tightening force, so that the fixing clamp 241 maintains a stable clamping force under long-term vibration conditions.
[0068] In a preferred embodiment of this utility model, such as Figure 8 As shown, the fixing clamp 241 has a limiting part 2411 that abuts against the end face of the flexible member 242, so that the limiting part 2411 and the end face of the flexible member 242 form a rigid stop to prevent the fixing clamp 241 from moving.
[0069] In this embodiment, the limiting part 2411 is a limiting plate connected to the positioning part, and two limiting plates with a gap are arranged on the same end face of the flexible member 242; preferably, the limiting part 2411 has a limiting part 2411 on both opposite sides, so that the two end faces of the flexible member 242 are arranged with limiting plates, further restricting the position of the fixing clip 241.
[0070] In one specific embodiment of this utility model, the bracket assembly 200 includes two mounting brackets 210 arranged at intervals along the horizontal direction. A first connecting beam 220 connects the upper parts of the two mounting brackets 210, and a second connecting beam 230 connects the lower parts of the two mounting brackets 210. Two oil separators 300 are respectively fixed to the two mounting brackets 210. It should be noted that the number of oil separators 300 is adjusted according to the number of compressors: two oil separators 300 are used for dual compressors, and one oil separator 300 is used for single compressors.
[0071] Understandably, the two mounting brackets 210 are connected by the first connecting beam 220 and the second connecting beam 230 to improve the overall stability of the bracket assembly 200.
[0072] Optionally, the number of second mounting positions 202 on the second connecting beam 230 may be less than the number of first mounting positions 201 on the first connecting beam 220. The pipelines connected to some of the solenoid valves 400 on the first mounting position 201 may be directly connected to other components inside the multi-split unit, or fixed by the pipeline bracket 250.
[0073] In this embodiment, the first connecting beam 220 has four first mounting positions 201 arranged horizontally, and the second connecting beam 230 has two second mounting positions 202 arranged horizontally. Each second mounting position 202 is connected to a first fixing component 240. It should be noted that the number of first mounting positions 201 on the first connecting beam 220 and the number of second mounting positions 202 on the second connecting beam 230 can be reasonably designed according to actual needs.
[0074] Furthermore, such as Figure 5 As shown, the mounting bracket 210 is connected to the pipe bracket 250, which has a third mounting position for fixing other pipes in the system to improve the stability of the pipes.
[0075] It is understood that the pipe support 250 includes a connecting plate connected to the mounting bracket 210, and a second fixing component 260 is provided on the connecting plate. The second fixing component 260 forms a third mounting position to fix the pipe.
[0076] It should be noted that the second fixing component 260 can adopt the same structure as the first fixing component 240, which will not be described in detail here.
[0077] In this embodiment, there are two pipe supports 250, one of which is located on the side of one of the mounting brackets 210, and the other is located at the bottom of the other mounting bracket 210. Of course, in other embodiments, the number and arrangement of the pipe supports 250 can be reasonably designed according to actual needs.
[0078] A second aspect of this utility model provides a multi-split air conditioning system, which includes the support structure provided in any of the above embodiments.
[0079] It is understood that, through the bracket structure, the multi-split air conditioning system in this embodiment can achieve the integrated design of oil separator 300 and solenoid valve 400 on bracket assembly 200. The bracket structure integrating oil separator 300 and solenoid valve 400 can achieve rapid assembly inside the multi-split air conditioning system, thereby improving production efficiency and maintenance convenience.
[0080] Optionally, the multi-split system includes an outdoor unit and multiple indoor units. The outdoor unit and multiple indoor units are all connected to a valve box device. The refrigerant can circulate within the outdoor unit, the valve box device, and the multiple indoor units to achieve the effect of one unit driving multiple units, that is, one outdoor unit can drive multiple indoor units through the valve box device.
[0081] Specifically, the outdoor unit is typically located outside the building and includes a compressor, condenser, oil separator 300, evaporator, and solenoid valve 400, used for refrigerant processing; the outdoor unit has the aforementioned support structure. The indoor unit is typically located inside the building and includes a heat exchanger. Buildings usually have multiple target spaces, and multiple indoor units are arranged one-to-one within each target space, allowing each indoor unit to regulate the air in a specific target space, achieving either cooling or heating. The valve box device can select the appropriate refrigerant and deliver it to the heat exchanger inside the indoor unit according to the cooling or heating needs of a specific target space, enabling the indoor unit to switch between different modes, such as cooling or heating.
[0082] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
