[0022] As can be seen from the above embodiments, the air conditioning system of this application simplifies the construction and assembly process of piping components, allowing users to arbitrarily increase or decrease the number of air conditioning units and piping components according to actual needs. Only the assembly of the piping components is required, without the need for large-scale modifications to the entire air conditioning system, effectively improving the scalability of the air conditioning system. Furthermore, since each air conditioning unit and piping component has an independent piping assembly, even if a partial unit failure or pipe damage occurs in the air conditioning system, only the faulty unit needs to be shut down and repaired, without affecting the operation of the entire air conditioning system, greatly improving the reliability, stability, and safety of the air conditioning system.

[0030] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0031] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0032] like Figure 1 As shown, the air conditioning system 100 of this application includes a first air conditioning unit 1, a second air conditioning unit 2, a first piping assembly 3, and a second piping assembly 4. The first piping assembly 3 includes a first inlet pipe 31 and a first outlet pipe 32 connected to the first air conditioning unit 1. The first piping assembly 3 also includes a first pressure regulating valve 33 connected to the first outlet pipe 32. The second piping assembly 4 includes a second inlet pipe 41 and a second outlet pipe 42 connected to the second air conditioning unit 2. The second piping assembly 4 also includes a second pressure regulating valve 43 connected to the second outlet pipe 42. The first inlet pipe 31 and the second inlet pipe 41 are connected. The first outlet pipe 32 and the second outlet pipe 42 are connected.

[0033] The air conditioning system 100 of this application adopts a modular piping structure. The first piping assembly 3 and the second piping assembly 4 are connected to the first air conditioning unit 1 and the second air conditioning unit 2, respectively. A first inlet pipe 31, a first outlet pipe 32, a second inlet pipe 41, and a second outlet pipe 42 are provided, thus equipping each air conditioning unit with its own detachable piping. This structural arrangement allows the air conditioning system 100 to be installed by prefabricating the various piping components and assembling them on-site. Compared to the traditional method that requires on-site measurement and welding of piping, the air conditioning system 100 of this application simplifies the construction and assembly process of the piping components. Furthermore, this modular design allows users to arbitrarily increase or decrease the number of air conditioning units and piping components according to actual needs, simply by assembling the piping components, without requiring large-scale modifications to the entire air conditioning system 100, effectively improving the scalability of the air conditioning system 100. Furthermore, since each air conditioning unit and piping assembly has its own independent piping assembly, even if the air conditioning system 100 experiences a partial unit failure or piping damage, it is only necessary to shut down the faulty unit and carry out maintenance, without affecting the operation of the entire air conditioning system 100, which greatly improves the reliability, stability and safety of the air conditioning system 100.

[0034] In addition, Figure 1 In the illustrated embodiment, the air conditioning system 100 is equipped with independent pressure regulating valves, namely a first pressure regulating valve 33 and a second pressure regulating valve 43, on the first outlet pipe 32 and the second outlet pipe 42, respectively. During actual operation, the air conditioning system 100 can independently control each air conditioning unit by independently controlling the first pressure regulating valve 33 and the second pressure regulating valve 43. This includes controlling the pressure of the air conditioning units, dynamically adjusting the pressure distribution within the pipes, and adjusting the water flow rate. This allows the air conditioning system 100 to flexibly adapt to different working environments and needs, effectively improving the flexibility, intelligence, and energy-saving performance of the air conditioning system 100.

[0035] It should be noted that this application only uses the first air conditioning unit 1 and the second air conditioning unit 2 as examples to describe the specific structure and connection method of the first piping assembly 3 and the second piping assembly 4. However, in actual application, as... Figure 1 As shown, the number of air conditioning units can be 3, 4, 5, 6, or even more. Therefore, the air conditioning system 100 can be assembled simply by connecting more piping components to the air conditioning units and interconnecting adjacent piping components. Thus, this application does not limit the number of air conditioning units and piping components.

[0036] In other alternative embodiments, the installation position of the pressure regulating valve can be arranged according to the actual operating conditions and requirements. For example, the first pressure regulating valve 33 can be set in the first inlet pipe 31, and the second pressure regulating valve 43 can be set in the second inlet pipe 41; or the first pressure regulating valve 33 can be set in the first outlet pipe 32, and the second pressure regulating valve 43 can be set in the second inlet pipe 41; or the first pressure regulating valve 33 can be set in the first inlet pipe 31, and the second pressure regulating valve 43 can be set in the second outlet pipe 42. This pattern continues for systems with a larger number of air conditioning units. With this structural arrangement, the air conditioning system 100 can independently control the inlet or outlet flow of each air conditioning unit according to the specific operating conditions and actual needs of different air conditioning units, thereby meeting the usage requirements under different application scenarios and ensuring the flexibility and adaptability of the air conditioning system 100. Therefore, this application does not limit the installation position of the pressure regulating valves of each unit.

[0037] refer to Figure 1 and Figure 2 As shown, in an optional embodiment, the air conditioning system 100 further includes a connector 5. The two ends of the connector 5 are respectively connected to a first inlet pipe 31 and a second inlet pipe 41.

[0038] The air conditioning system 100 directly connects the first inlet pipe 31 and the second inlet pipe 41 via connector 5, reducing complex connection points between pipes and lowering installation difficulty. Compared to traditional pipe systems requiring multiple joints or splicing points, the connection method of this application is simpler and more convenient, effectively improving the efficiency of the assembly process. Simultaneously, the design of connector 5 facilitates disassembly and replacement. For example, when the air conditioning system 100 needs maintenance or repair of a certain pipe component, the pipe component can be disassembled by removing connector 5 without dismantling the entire air conditioning system 100's piping; or, when the air conditioning system 100 needs to add an air conditioning unit, there is no need to replace the pipe component; simply connect the new pipe component to the existing pipe component via connector 5. Therefore, the connector 5 enables the air conditioning system 100 to more efficiently complete processes such as pipe assembly, module construction, and installation of new equipment in practical applications, greatly improving the installation, disassembly, and maintenance efficiency of the air conditioning system 100.

[0039] Of course, in another optional embodiment, connector 5 is configured to connect the first outlet pipe 32 and the second outlet pipe 42 at its two ends, respectively. That is, the outlet pipes of the piping assembly can also be assembled using connector 5. Figure 1 and Figure 2 In the embodiment shown, both the inlet and outlet pipes of the piping assembly are equipped with connectors 5 for assembly, thereby further improving the efficiency of piping assembly and expanding the applicability of the air conditioning system 100.

[0040] In an optional embodiment, the first air conditioning unit 1 includes a first heat manager 11, with a first inlet pipe 31 and a first outlet pipe 32 respectively connected to the first heat manager 11. A first pressure regulating valve 33 is disposed between the first outlet pipe 32 and the first heat manager 11.

[0041] In actual operation, the air conditioning system 100 can independently control the first heat manager 11 by controlling the opening degree of the first pressure regulating valve 33. For example, it can control the internal pressure of the first heat manager 11, dynamically adjust the pressure distribution in the first inlet pipe 31 and the first outlet pipe 32, and adjust the water flow rate in the first inlet pipe 31 and the first outlet pipe 32. This allows the first air conditioning unit 1 to flexibly adapt to different working environments and needs, effectively improving the flexibility, intelligence and energy-saving performance of the air conditioning system 100.

[0042] Similarly, as Figure 2 As shown, the second air conditioning unit 2 includes a second heat exchanger 21, with a second inlet pipe 41 and a second outlet pipe 42 respectively connected to the second heat exchanger 21. A second pressure regulating valve 43 is disposed between the second outlet pipe 42 and the second heat exchanger 21. Therefore, during the operation of the air conditioning system 100, the second heat exchanger 21 can be independently controlled by controlling the opening degree of the second pressure regulating valve 43. As described above, this application does not limit the number of air conditioning units, but can set them according to actual operating conditions and needs. That is to say, for Figure 1 In the illustrated embodiment, each air conditioning unit includes an independent heat manager and is connected to it via corresponding piping assemblies, thereby enabling independent control. Therefore, this application does not limit the number or connection relationship of heat managers and piping assemblies.

[0043] In an optional embodiment, the first inlet pipe 31 is connected to the first heat manager 11, the first outlet pipe 32 is connected to the first heat manager 11, the second inlet pipe 41 is connected to the second heat manager 21, and the second outlet pipe 42 is connected to the second heat manager 21 via connectors 5. This design enables the air conditioning system 100 to complete pipe assembly, module construction, and equipment installation more efficiently in practical applications, greatly improving the installation, disassembly, and maintenance efficiency of the air conditioning system 100.

[0044] Of course, the structure of the connector 5 in this application is a flange structure, meaning that different pipes are connected, as well as between the pipe and the heat manager, through a flange structure. In other optional embodiments, the structure of the connector 5 can be flexibly configured, for example: it can be configured only between the first inlet pipe 31 and the first heat manager 11, or only between the first outlet pipe 32 and the first heat manager 11, or only between the second inlet pipe 41 and the second heat manager 21, or only between the second outlet pipe 42 and the second heat manager 21, etc.; and the specific structure of the connector 5 can also be changed accordingly, for example: it can adopt a bolt structure, or waterproof tape, or a snap-fit ​​structure, etc. Therefore, this application does not impose any limitations on this.

[0045] In an optional embodiment, the first pressure regulating valve 33 is connected between the connector 5 and the first heat manager 11, and the second pressure regulating valve 43 is connected between the connector 5 and the second heat manager 21. Therefore, during the assembly of the air conditioning system 100, it is only necessary to place the pressure regulating valve between the pipeline and the heat manager and install it via the connector 5, without needing to design a specific installation structure for the pressure regulating valve separately, such as opening connection holes or mounting grooves in the pipeline. Thus, through this design, the air conditioning system 100 improves its assembly efficiency while ensuring the integrity and unity of the pipeline, guaranteeing the sealing of the pipeline components, and improving production efficiency.

[0046] In an optional embodiment, when the number of units in the air conditioning system 100 is less than or equal to 4, the pipe diameter of the first pipe assembly 3 and the second pipe assembly 4 is greater than or equal to 215 mm and less than or equal to 225 mm. Specifically, it can be designed to be 215 mm, 216 mm, 217 mm, 218 mm, 219 mm, 220 mm, 221 mm, 222 mm, 223 mm, 224 mm, or 225 mm. This is because the number of units in the air conditioning system 100 is relatively small, the required water flow is relatively low, and the extension resistance of the pipes connected to each unit is also different. Therefore, selecting a smaller diameter pipe can better adapt to the water flow required by the system, ensure the operating efficiency of each unit, and match the extension resistance of each unit. When the number of units in the air conditioning system 100 is greater than 4 and less than or equal to 6, the pipe diameter of the first pipe assembly 3 and the second pipe assembly 4 is greater than or equal to 270 mm and less than or equal to 280 mm. Specifically, the pipe diameters can be designed to be 270mm, 271mm, 272mm, 273mm, 274mm, 275mm, 276mm, 277mm, 278mm, 279mm, or 280mm. As the number of units in the air conditioning system 100 increases, the required water flow rate also increases. Therefore, larger diameter pipes are selected to accommodate the higher water flow rate requirements and ensure the operating efficiency of each unit. For air conditioning systems 100 with a larger number of units, the dimensions of the pipe components are adjusted accordingly; therefore, this application does not impose any restrictions on this.

[0047] In an optional embodiment, the air conditioning system 100 further includes multiple blocking members 6. The location of the blocking members 6 can be configured according to specific operating conditions and usage requirements, for example, in combination with... Figure 1 and Figure 2 In the embodiment where the inlet and outlet are on the same side, the red arrow represents the inlet flow direction and the blue arrow represents the outlet flow direction. It is evident that the air conditioning system 100 requires inlet and outlet operations on only one side. Therefore, the blocking members 6 can be positioned on the side of the piping assembly furthest from the inlet and outlet, thus forming a complete closed loop. In the embodiment that includes only the first air conditioning unit 1 and the second air conditioning unit 2, the blocking members 6 are respectively installed at the end of the second inlet pipe 41 furthest from the first inlet pipe 31, and at the end of the second outlet pipe 42 furthest from the first outlet pipe 32.

[0048] This design enables the air conditioning system 100 to form a reverse-flow piping connection scheme, meaning that the fluid travels different distances from inflow to outflow for different units. Because the fluid travel distance differs between units in this reverse-flow piping connection scheme, the fluid pressure also varies. When some units are operating at low load, the air conditioning system 100 can close the pressure regulating valves of those units, leaving only the units with shorter travel distances operational. This improves the overall operating efficiency of the air conditioning system 100 at the same flow rate, resulting in a more balanced load distribution among the units and effectively preventing some units from operating at low load and inefficiently.

[0049] Correspondingly, in the embodiment where the inlet and outlet are located on opposite sides, the air conditioning system 100 needs to perform water intake and outlet operations on both sides respectively. Therefore, for the inlet pipe of the piping assembly, the blocking member 6 can be placed on the side away from the inlet (near the outlet), while for the outlet pipe of the piping assembly, the blocking member 6 is placed on the side away from the outlet (near the inlet), thus forming a complete closed loop. In the embodiment that includes only the first air conditioning unit 1 and the second air conditioning unit 2, the blocking member 6 is respectively installed at the end of the first outlet pipe 32 away from the second outlet pipe 42, and at the end of the second inlet pipe 41 away from the first inlet pipe 31.

[0050] This design enables the air conditioning system 100 to form a parallel piping connection scheme, meaning that for different units, the fluid travels the same distance from inflow to outflow. This ensures that the resistance of each branch pipe is the same, resulting in a more uniform fluid flow distribution within the piping assembly. It also reduces pressure fluctuations and instability within the piping assembly, improving the operational stability of the air conditioning system 100.

[0051] In such Figure 1 and Figure 2 In the optional embodiment shown, the first heat manager 11 includes a first evaporator 111 and a first condenser 112, and the second heat manager 21 includes a second evaporator 211 and a second condenser 212. A first inlet pipe 31 includes a first evaporator 111 inlet pipe connected to the first evaporator 111 and a first condenser 112 inlet pipe connected to the first condenser 112. A first outlet pipe 32 includes a first evaporator 111 outlet pipe connected to the first evaporator 111 and a first condenser 112 outlet pipe connected to the first condenser 112. A second inlet pipe 41 includes a second evaporator 211 inlet pipe connected to the second evaporator 211 and a second condenser 212 inlet pipe connected to the second condenser 212. A second outlet pipe 42 includes a second evaporator 211 outlet pipe connected to the second evaporator 211 and a second condenser 212 outlet pipe connected to the second condenser 212.

[0052] With this design, the air conditioning system 100 can independently control the evaporator and condenser of each unit, such as regulating the cylinder pressure, water flow rate, and water pressure. This allows the first air conditioning unit 1 to flexibly adapt to different working environments and needs, effectively improving the flexibility, intelligence, and energy-saving performance of the air conditioning system 100.

[0053] Of course, the specific solutions will vary for different air conditioning systems 100. For example, in some optional embodiments, only an evaporator inlet pipe or a condenser inlet pipe may be provided, or only an evaporator outlet pipe or a condenser outlet pipe may be provided, so as to adapt to different unit types and operating schemes. Therefore, this application does not limit this.

[0054] In an optional embodiment, the air conditioning system 100 further includes a control unit. The control unit is electrically connected to the first air conditioning unit 1, the second air conditioning unit 2, the first pressure regulating valve 33, and the second pressure regulating valve 43, respectively. The control unit is used to control the opening degree of the first pressure regulating valve 33 and the second pressure regulating valve 43 according to the operating state of the first air conditioning unit 1 and the second air conditioning unit 2. The operating state is one of the following: full load state, partial load state, or no-load state.

[0055] The air conditioning system 100, through the installation of control components, can dynamically adjust the opening of the pressure regulating valve according to the operating status (full load, partial load, or no load) of the first air conditioning unit 1 and the second air conditioning unit 2. Specifically, under full load, the pressure regulating valve can be opened to the maximum to ensure efficient system operation; under partial load, the opening of the pressure regulating valve can be appropriately reduced, or the regulating valves of some units can be completely closed to avoid energy waste; and for units under no load, their pressure regulating valves can be completely closed to completely stop unnecessary energy consumption. Therefore, this dynamic adjustment mechanism significantly improves the energy efficiency ratio of the air conditioning system 100, reduces operating costs, improves user comfort, reduces energy loss within the system, and further enhances the overall performance of the air conditioning system 100. Furthermore, through the above design, the air conditioning system 100 can also rationally allocate the load according to actual needs, avoiding prolonged extreme operating conditions for equipment, thereby extending the service life of the air conditioning units and pressure regulating valves, and improving the stability and reliability of the air conditioning system 100.

[0056] Overall, in practical application scenarios, the air conditioning system 100 solution described in this application can effectively address the following issues: Figure 3The piping units shown are prefabricated to ensure consistent dimensions and flow rates throughout the piping system. At the construction site, piping is constructed based on the actual installation location, the required number of units, and the construction distance. This involves selecting appropriate piping units, connecting piping components, pressure regulating valves, and other parts to the units, and assembling piping components from adjacent units to form modular parallel units. Compared to traditional piping systems requiring on-site measurement, processing, and welding, this solution allows for more efficient piping construction. Furthermore, individual modules can be disassembled, repaired, and cleaned during use, significantly reducing installation and operating costs. Additionally, this solution enables piping expansion; when new units are needed, modular piping components can be directly connected to the existing piping system without disassembling it. This design effectively improves the scalability of the air conditioning system 100.

[0057] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
