[0065] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where 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 by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0066] At present, the air-conditioning system mainly uses pipe structures as carriers for refrigerant in the whole system and for connecting other components. Most conventional pipes use copper pipes or steel pipes to connect various components. When designing the pipes, the clearance requirements between the pipelines need to be considered. Therefore, the occupied space of the pipes accounts for a relatively large proportion in the whole air-conditioning system, which is likely to interfere with the layout of other structures in the air-conditioning system, and will increase the volume of the air-conditioning system, which is not conducive to the layout of the air-conditioning system and has a high cost.

[0067] Reference is made below to Figures 1 - 10 describe the valve island assembly according to an embodiment of the present invention.

[0068] The valve island assembly 1 according to the present invention includes: a valve island body 11, a plate heat exchanger 12 and a valve body. A plurality of valve island interfaces are formed on one side surface of the valve island body 11, and a communication flow channel is formed inside the valve island body 11 to communicate at least two valve island interfaces; the plate heat exchanger 12 is arranged on one side of the valve island body 11, and the plate heat exchanger 12 has a plurality of plate heat exchanger interfaces, and at least one plate heat exchanger interface is communicated with a corresponding valve island interface; the valve body is arranged on one side of the valve island body 11 and is communicated with the corresponding valve island interface.

[0069] The valve island assembly 1 according to the present invention is provided with a valve island body 11. The valve island body 11 can be understood as the basic platform of the valve island assembly 1. A plurality of valve island interfaces are arranged on one side surface of the valve island body 11. The plurality of valve island interfaces can be respectively communicated with external pipeline structures, and at least two valve island interfaces inside the valve island body 11 are communicated with each other. Therefore, the refrigerant transported by other external structures can flow into the valve island body 11 through different valve island interfaces and flow inside the valve island body 11, and then can flow to the required position through the valve island assembly 1. The plate heat exchanger 12 is arranged on one side of the valve island body 11. A plurality of plate heat exchanger interfaces are arranged on the plate heat exchanger 12, and at least one plate heat exchanger interface is communicated with the corresponding valve island interface. Thus, the refrigerant flowing inside the valve island body 11 can enter the plate heat exchanger 12 through the valve island interface for heat exchange, or the heat-exchanged refrigerant can flow into the valve island body 11 from the plate heat exchanger 12. A valve body communicated with the corresponding valve island interface is also arranged on one side of the valve island body 11. The valve body can control the flow of the refrigerant in the corresponding valve island interface. For example, the flow of the refrigerant to different positions inside the valve island body 11 can be controlled by controlling the opening and closing of the valve body, realizing the controllability of the valve island assembly 1 for the flow of the refrigerant.

[0070] The valve island assembly 1 is an integrated component in the air conditioning system 2. The valve island assembly 1 can be simply understood as integrating the conventional piping in the traditional air conditioning system within one structure. Each valve island interface is equivalent to a piping structure in the traditional air conditioning system. The valve island assembly 1 integrates multiple different valve island interfaces on the valve island body 11, and integrates the plate heat exchanger 12 and multiple valve bodies on the valve island body 11, and uses the connecting flow channels inside the valve island body 11 to connect each valve island interface, reducing the space occupied by the pipe connections in the traditional air conditioning system, and can avoid interference with the assembly of other structures in the air conditioning system 2. The integrated design makes the overall structure of the air conditioning system 2 more compact, helps to realize the miniaturization of the overall structure of the air conditioning system 2, and provides convenience for the installation of the air conditioning system 2 in a limited space.

[0071] Since the valve island assembly 1 integrates the functions of multiple pipings in the traditional air conditioning system and reduces the use of traditional pipings, therefore, the design of the valve island assembly 1 can reduce the material cost and labor cost of the piping scheme in the traditional air conditioning system. At the same time, the integrated design can also improve the production efficiency, reduce the time and resource consumption in the production process, and further reduce the manufacturing cost.

[0072] In addition, the valve island interfaces of the valve island assembly 1 are located on one side surface of the valve island body 11. When the valve island assembly 1 is welded to other structures in the air conditioning system 2, there is no need to change the direction of the valve island, which improves the welding efficiency. At the same time, the integrated design of the valve island assembly 1 makes the valve island interfaces concentrated on the valve island body 11, which can avoid the installation complexity caused by the need to assemble different pipe structures at different positions in the traditional air conditioning system, and then reduces the assembly difficulty of the entire air conditioning system 2, making the installation and maintenance of the air conditioning system 2 more convenient. There are problems such as many solder joints and low reliability in the pipe connection method in the traditional air conditioning system, while the valve island assembly 1 reduces the number of solder joints through the integrated design, thereby reducing the leakage risk caused by poor welding.

[0073] According to an embodiment of the present invention, a protruding valve block is formed on one side surface of the valve island body 11, and a plurality of first valve island interfaces are formed on the side wall of the valve block. The plate heat exchanger 12 is arranged on the side wall of the valve block and the plate heat exchanger interface is communicated with the plurality of first valve island interfaces.

[0074] Such as Figures 1 - 9As shown, protruding valve blocks are provided on some surfaces of the valve island body 11. The protruding design of the valve blocks enhances the overall structural stability of the valve island assembly 1. Multiple first valve island interfaces are formed on the side walls of the valve blocks. The multiple first valve island interfaces are concentrated on the side walls of the valve blocks, making the layout of the valve island interfaces on the valve island assembly 1 more compact. The plate heat exchanger 12 is arranged on the side wall of the valve block. Therefore, the valve block can support and limit the plate heat exchanger 12 on one side surface of the valve island body 11, preventing the plate heat exchanger 12 from shaking or shifting on the valve island body 11. Multiple plate heat exchanger interfaces are provided on the plate heat exchanger 12, and each plate heat exchanger interface corresponds to and communicates with a first valve island interface, realizing the communication between the plate heat exchanger 12 and the valve island body 11. Furthermore, the refrigerant can flow between the plate heat exchanger 12 and the valve island body 11, facilitating the inflow of the refrigerant from the valve island body 11 into the plate heat exchanger 12 for heat exchange or the return of the refrigerant to the valve island body 11 after heat exchange in the plate heat exchanger 12. By arranging the plate heat exchanger 12 on the side wall of the valve block and connecting the plate heat exchanger interfaces with the multiple first valve island interfaces, direct and efficient connection between the interfaces is achieved, reducing the use of intermediate pipelines, lowering the resistance of refrigerant flow, and improving the operating efficiency of the system. The protruding valve block design enables the plate heat exchanger 12 to fit more closely to the valve island body 11, making full use of the space on the side of the valve island body 11, making the overall layout of the valve island assembly 1 more compact, contributing to reducing the overall volume of the valve island assembly 1, and realizing the miniaturization of the air conditioning system 2.

[0075] According to an embodiment of the present invention, the opening directions of the multiple first valve island interfaces are arranged parallel to one side surface of the valve island body 11. As Figures 1 - 9 shown, the opening directions of the multiple first valve island interfaces are arranged parallel to one side surface of the valve island body 11, that is, the multiple first valve island interfaces open on the side wall of the valve block, and the opening directions are parallel to one side surface of the valve island body 11. During the installation process, the plate heat exchanger interfaces on the plate heat exchanger 12 can be more easily docked with the first valve island interfaces without complex angle adjustment or space flipping, thus simplifying the installation process and improving the installation efficiency. Installers can more intuitively see the interface positions during operation, reducing installation difficulties caused by limited viewing angles or narrow spaces, and can more easily ensure the correct alignment and fastening between the plate heat exchanger interfaces and the first valve island interfaces. The installation process is more convenient, improving the reliability and safety of the air conditioning system 2.

[0076] According to an embodiment of the present invention, a support platform extending to the bottom of the plate heat exchanger 12 is formed on the valve island body 11. As Figures 1 - 9As shown, the support platform extends to the bottom of the plate heat exchanger 12, which can support the plate heat exchanger 12, enabling the plate heat exchanger 12 to be more easily positioned and fixed on the valve island body 11 during installation. Moreover, the support platform can effectively disperse the weight of the plate heat exchanger 12 and the stress generated during operation, ensuring the stability of the plate heat exchanger 12, thereby improving the stability and durability of the entire valve island assembly 1. Through the firm support of the support platform for the plate heat exchanger 12, the valve island assembly 1 can maintain a more stable state during operation, reducing problems such as interface loosening and leakage caused by vibration or shaking, and improving the overall operation stability and reliability of the system.

[0077] The design of the support platform not only provides the necessary support function but also can optimize the space utilization and layout of the valve island assembly 1 to a certain extent. The support platform enables the plate heat exchanger 12 to be more closely integrated on the valve island body 11, reducing unnecessary space waste, and also contributing to the miniaturization and compact design of the entire air conditioning system 2.

[0078] According to an embodiment of the present invention, at least two valve blocks are provided on the valve island. A plurality of first valve island interfaces are provided on one of the valve blocks. The plate heat exchanger 12 is disposed between two adjacent valve blocks, or the plate heat exchanger 12 is disposed on the surface of one of the valve blocks facing away from the other valve block.

[0079] During actual design, a plurality of valve blocks can be provided on the valve island body 11, and different valve island interfaces can be provided on each valve block to facilitate more flow paths of the refrigerant in the valve island (i.e., the valve island can integrate the functions of multiple pipelines in a traditional air conditioning system). For example, at least two valve blocks can be provided on the valve island body 11, and a plurality of first valve island interfaces are provided on the side wall of one of the valve blocks. When installing the plate heat exchanger 12, the assembly position of the plate heat exchanger 12 can be selected according to actual needs. Specifically, the plate heat exchanger 12 can be assembled between two adjacent valve blocks, or the plate heat exchanger 12 can be disposed on the surface of one of the valve blocks facing away from the other valve block. Different installation positions make the assembly of the plate heat exchanger 12 more flexible, and the valve island assembly 1 can perform a reasonable assembly design of the plate heat exchanger 12 according to actual dimensions or assembly requirements. Disposing the plate heat exchanger 12 between the valve blocks or on the surface of the valve blocks can make full use of the space of the valve island assembly 1, reduce unnecessary pipeline connections and space occupation, make the layout of the valve island assembly 1 more compact, contribute to improving the integration degree of the valve island assembly 1, and further make the entire air conditioning system 2 more compact.

[0080] According to an embodiment of the present invention, the plate heat exchanger 12 is arranged parallel to or perpendicular to one side surface of the valve island body 11 in the length direction. During assembly, the plate heat exchanger 12 can be arranged parallel to or perpendicular to one side surface of the valve island body 11 in the length direction (i.e., the length direction of the plate heat exchanger 12). The different arrangement modes of the plate heat exchanger 12 enable the valve island assembly 1 to flexibly adjust the plate heat exchanger 12 according to different installation space and layout requirements. Whether it is a compact installation environment with limited space or a specific layout that requires optimizing the fluid path, the best adaptation can be achieved by adjusting the installation direction of the plate heat exchanger 12. The installer can select the most suitable installation direction according to the actual situation without complex modification or adjustment of the valve island assembly 1. At the same time, during maintenance, it is also easier to access and inspect the plate heat exchanger 12, improving the convenience and efficiency of maintenance. Allowing the plate heat exchanger 12 to be installed in different directions provides more choices and possibilities for the assembly of the valve island assembly 1, enabling the valve island assembly 1 to adapt to air-conditioning systems 2 in different application scenarios, and thus meeting different requirements, with high flexibility.

[0081] In addition, by adjusting the installation direction of the plate heat exchanger 12, the flow path and speed of the refrigerant in the heat exchanger can be affected, thereby optimizing the heat exchange efficiency. In some cases, installation parallel to the surface of the valve island body 11 may be more conducive to the uniform distribution of the refrigerant and efficient heat exchange; in other cases, vertical installation may be more helpful in reducing fluid resistance and improving the overall performance of the system.

[0082] In some embodiments, the plate heat exchanger 12 is arranged parallel to some surfaces of the valve island body 11 in the length direction, that is, the plate heat exchanger 12 is placed horizontally at this time; the plate heat exchanger 12 is arranged perpendicular to some surfaces of the valve island body 11 in the length direction, that is, the plate heat exchanger 12 is placed vertically at this time.

[0083] According to an embodiment of the present invention, four plate heat exchanger interfaces are provided on one side of the plate heat exchanger 12 facing the valve island body 11, and the four plate heat exchanger interfaces are arranged in a rectangle; four first valve island interfaces are provided on the valve block, and the four first valve island interfaces are arranged in a corresponding rectangle and are respectively communicated with the corresponding plate heat exchanger interfaces.

[0084] The four plate heat exchanger interfaces on the plate heat exchanger 12 are arranged in a rectangle, and the four first valve island interfaces on the valve block are also arranged in a corresponding rectangle. This standardized interface layout design makes the connection between the two more efficient and accurate. The rectangular arrangement helps to ensure that each interface can be accurately aligned with the corresponding valve island interface, reducing connection problems caused by interface misalignment and improving the reliability and stability of the system. Since the plate heat exchanger interface layout is standardized and corresponds one-to-one with the first valve island interface, installers can complete the operation of connecting the plate heat exchanger 12 and the valve block more quickly and accurately, reducing the error rate during installation, shortening the commissioning time, and improving the overall installation efficiency.

[0085] In some embodiments, among the four plate heat exchanger interfaces on the plate heat exchanger 12, two of them can be connected to each other, and the other two can also be connected to each other, that is, two refrigerant flow paths can be formed in the plate heat exchanger 12, and the refrigerant in the two refrigerant flow paths can exchange heat in the plate heat exchanger 12.

[0086] In some embodiments, more flow channels can also be formed in the plate heat exchanger 12.

[0087] According to an embodiment of the present invention, at least two of the multiple valve island interfaces are configured as a first indoor heat exchanger interface 148 and a second indoor heat exchanger interface 158; wherein, the first indoor heat exchanger interface 148 and the second indoor heat exchanger interface 158 are respectively arranged on two valve blocks or the same valve block, and the first indoor heat exchanger interface 148 and the second indoor heat exchanger interface 158 are open towards the same-side edge of the valve island body 11.

[0088] Such as Figures 1 - 9As shown, at least two of the multiple valve island interfaces are the first indoor heat exchanger interface 148 and the second indoor heat exchanger interface 158. That is, the refrigerant in the valve island body 11 can flow into the indoor heat exchanger through the first indoor heat exchanger interface 148 (or the second indoor heat exchanger interface 158) and exchange heat with the indoor air to realize the refrigeration or heating function of the air conditioning system 2. Then, the refrigerant flows back to the valve island body 11 (or flows to other structures) through the second indoor heat exchanger interface 158 (or the first indoor heat exchanger interface 148) for recycling. By respectively arranging the first indoor heat exchanger interface 148 and the second indoor heat exchanger interface 158 on two valve blocks or the same valve block and both opening towards the same-side edge of the valve island body 11, the valve island assembly 1 provides greater connection flexibility. That is, the valve island assembly 1 can flexibly choose to arrange the two indoor heat exchanger interfaces on different valve blocks of the valve island body 11 or centrally manage multiple indoor heat exchanger interfaces on the same valve block according to the specific configuration requirements of the air conditioning system 2, so as to adapt to the diverse designs of the air conditioning system 2. Since the two indoor heat exchanger interfaces open towards the same-side edge of the valve island body 11, installers can operate more conveniently when connecting the indoor heat exchanger, reducing the complexity and difficulty of wiring, helping to shorten the installation time, improve the installation efficiency, and reduce the failure risk caused by improper wiring.

[0089] In some embodiments, the first indoor heat exchanger interface 148 is externally connected to a high-pressure valve 101, and the second indoor heat exchanger interface 158 is externally connected to a low-pressure valve 102.

[0090] In some embodiments, both the high-pressure valve 101 and the low-pressure valve 102 can be globe valves.

[0091] According to an embodiment of the present invention, the first indoor heat exchanger interface 148 and the second indoor heat exchanger interface 158 face the first side edge of the valve island body 11 and are open, and the first valve island interface faces the second side edge of the valve island body 11 and is open; wherein, the first side edge and the second side edge are adjacent side edges of the valve island body 11. By arranging the first indoor heat exchanger interface 148 and the second indoor heat exchanger interface 158 to face the first side edge of the valve island body 11 and the first valve island interface to face the adjacent second side edge of the valve island body 11, the valve island assembly 1 optimizes the layout of the valve island interfaces, enabling different types of valve island interfaces to be located on different side edges of the valve island body 11 respectively, which helps to reduce the interference between the valve island interfaces, improve the space utilization rate, enable the valve island assembly 1 to accommodate more interfaces in a limited space, and meet the connection requirements of more complex air conditioning systems 2. Since different types of interfaces are located on different side edges of the valve island body 11 respectively, installers can operate more conveniently when connecting or disconnecting the interfaces without having to switch on multiple faces of the valve island assembly 1, thus improving the installation and maintenance efficiency. At the same time, this layout also enables maintenance personnel to more easily identify and access each interface, reducing the difficulty and cost of maintenance.

[0092] According to an embodiment of the present invention, one of the two valve blocks is configured as the first valve block 131; wherein, the surface of the first valve block 131 facing the first side edge is provided with the first indoor heat exchanger interface 148, and the other surface of the first valve block 131 is provided with the first plate heat exchanger interface 141. The first indoor heat exchanger interface 148 is in communication with the first plate heat exchanger interface 141, and the first plate heat exchanger interface 141 is adapted to connect to the first flow path of the plate heat exchanger 12.

[0093] As Figures 1 - 9 shown, the design of the first valve block 131 arranges the first indoor heat exchanger interface 148 and the first plate heat exchanger interface 141 on its opposite two surfaces respectively, realizing the integration of the first indoor heat exchanger interface 148 and the first plate heat exchanger interface 141 and optimizing the space utilization. By integrating interfaces with different functions on the same valve block, the number of independent components in the valve island assembly 1 is reduced, making the entire system more compact and helping to reduce the overall volume of the air conditioning system 2.

[0094] The first indoor heat exchanger interface 148 is in communication with the first interface 141 of the plate heat exchanger. At the same time, the first interface of the plate heat exchanger 12 is in communication with the first flow path of the plate heat exchanger 12. The refrigerant can enter the first flow path of the plate heat exchanger 12 through the first interface 141 of the plate heat exchanger. Specifically, the refrigerant flowing out of the indoor heat exchanger can enter the valve island body 11 through the first indoor heat exchanger interface 148 and flow towards the first interface 141 of the plate heat exchanger, and then flow into the plate heat exchanger 12 through the first interface 141 of the plate heat exchanger for heat exchange, simplifying the flow path of the refrigerant in the valve island assembly 1. This direct connection method inside the valve island body 11 reduces the flow path of the refrigerant and eliminates the need to set up additional connecting pipelines, improving the compactness of the valve island assembly 1.

[0095] According to an embodiment of the present invention, a second interface 142 of the plate heat exchanger is provided on the other surface of the first valve block 131, and a plurality of shunt ports communicating with the inside of the second interface 142 of the plate heat exchanger are formed on the first valve block 131. As Figures 1 - 9 shown, the second interface 142 of the plate heat exchanger is provided on the other surface of the first valve block 131 (the same surface as the surface where the plate heat exchanger interface is located), ensuring that when the plate heat exchanger 12 is assembled, it can be directly opposite and in communication with both the first interface 141 and the second interface 142 of the plate heat exchanger.

[0096] The second interface 142 of the plate heat exchanger provided on the first valve block 131 and the plurality of shunt ports communicating with its inside enable the refrigerant to be effectively shunted before entering the plate heat exchanger 12, which helps to ensure the uniform distribution of the refrigerant in the plate heat exchanger 12, thereby improving the heat exchange efficiency and reducing the local overheating or overcooling phenomenon caused by uneven refrigerant distribution. Through the design of the plurality of shunt ports, the valve island assembly 1 can adapt to plate heat exchangers 12 of different specifications and models, as well as the requirements of different air conditioning systems 2. This flexibility enables the valve island assembly 1 to be widely used in various scenarios, improving its market adaptability and competitiveness. Moreover, the first valve block 131 integrates the shunt function on the first valve block 131, making the shunt structure on the valve block assembly more concentrated, improving the compactness of the valve block assembly structure, and further reducing the volume of the air conditioning system 2.

[0097] According to an embodiment of the present invention, a first shunt port 145 is provided on the top of the first valve block 131; the valve island assembly 1 further includes: a first expansion valve 182, the first expansion valve 182 is disposed on one side surface of the valve island body 11 and the inlet of the first expansion valve 182 is in communication with the first shunt port 145, and the outlet of the first expansion valve 182 is adapted to be in communication with the second flow path of the plate heat exchanger 12, and the second flow path of the plate heat exchanger 12 is adapted to exchange heat with the first flow path.

[0098] As Figures 1 - 9As shown, a first flow splitting port 145 is provided at the top of the first valve block 131. During assembly, the first expansion valve 182 can be arranged on the surface of the valve island body 11 and the inlet of the first expansion valve 182 is communicated with the first flow splitting port 145. The refrigerant flowing through the plate heat exchanger 12 flows in the valve island body 11 to the first flow splitting port 145 and enters the first expansion valve 182 through the first flow splitting port 145. At the same time, the outlet of the first expansion valve 182 is communicated with the second flow path of the plate heat exchanger 12. The refrigerant passing through the first expansion valve 182 can flow into the second flow path of the plate heat exchanger 12 and exchange heat with the refrigerant in the first flow path of the plate heat exchanger 12. The first expansion valve 182 can change the temperature and pressure of the refrigerant, creating a temperature difference between the first flow path and the second flow path of the plate heat exchanger 12, facilitating the heat exchange between the refrigerants in the two flow paths, and thus optimizing the overall heat exchange performance of the plate heat exchanger 12. Moreover, by precisely controlling the refrigerant flow rate entering the second flow path through the first expansion valve 182, it can ensure that the refrigerant heat exchange process between the first flow path and the second flow path of the plate heat exchanger 12 is more sufficient and efficient, thereby improving the energy efficiency ratio of the entire air conditioning system 2.

[0099] According to an embodiment of the present invention, the valve island assembly 1 further includes: a first solenoid valve 181. The first solenoid valve 181 is provided with a first solenoid valve 181 inlet and a first solenoid valve 181 outlet that can be selectively conducted. The first solenoid valve 181 is arranged upstream or downstream of the first expansion valve 182 and is used to connect the first expansion valve 182 with the second flow path. By introducing the first solenoid valve 181 and arranging it upstream or downstream of the first expansion valve 182, the valve island assembly 1 realizes flexible control of the refrigerant flow path. The first solenoid valve 181 has a selectively conductive first solenoid valve 181 inlet and outlet, which means that the system can selectively open or close the channel for the refrigerant to flow to the second flow path of the plate heat exchanger 12 according to actual needs, thereby enhancing the control flexibility and adaptability of the air conditioning system 2. In the case where it is necessary to cut off the refrigerant flow to the second flow path of the plate heat exchanger 12 (for example, during maintenance, repair, or system failure), the first solenoid valve 181 can be quickly closed to prevent the refrigerant from continuing to flow, thereby protecting the air conditioning system 2 from potential damage, improving the safety and reliability of the system, and reducing the risk of failures caused by refrigerant leakage or improper flow. By precisely controlling the opening and closing of the first solenoid valve 181, the air conditioning system 2 can adjust the refrigerant flow rate and distribution according to actual needs, thereby optimizing the energy efficiency of the system. In addition, integrating the first solenoid valve 181 into the valve island assembly 1 and connecting it to the first expansion valve 182 and the second flow path of the plate heat exchanger 12 makes the structure of the entire valve island assembly 1 more compact, contributing to the miniaturization of the air conditioning system 2.

[0100] According to an embodiment of the present invention, one of the multiple valve island interfaces is configured as the first solenoid valve interface 155, and one of the multiple valve island interfaces is configured as the first expansion valve interface 151. The first solenoid valve interface 155 and the first expansion valve interface 151 are connected inside the valve island body 11; the inlet of the first solenoid valve 181 is connected to the first diversion port 145, the outlet of the first solenoid valve 181 is connected to the first solenoid valve interface 155; the inlet of the first expansion valve 182 is connected to the first expansion valve interface 151.

[0101] As Figures 1 - 9 shown, the first expansion valve interface 151 and the first solenoid valve interface 155 are provided on the valve island body 11, and the first expansion valve interface 151 and the first solenoid valve interface 155 are connected inside the valve island body 11. By connecting the first solenoid valve interface 155 and the first expansion valve interface 151 inside the valve island body 11, the connection of the internal pipelines of the air-conditioning system 2 is simplified, the use of external pipelines is reduced, the occupied space of the valve island assembly 1 can be reduced, and the layout of the entire air-conditioning system 2 can be made more compact. Since the inlet of the first solenoid valve 181 is connected to the first diversion port 145, the outlet of the first solenoid valve 1 is connected to the first solenoid valve interface 155, and the inlet of the first expansion valve 182 is connected to the first expansion valve interface 151, therefore, the refrigerant in the first flow path of the plate heat exchanger 12 can flow through the first diversion port 145 to the first solenoid valve 181. If the first solenoid valve 181 is opened, the refrigerant can continue to flow and flow back to other positions of the valve island body 11 after passing through the first solenoid valve interface 155. The design of the first solenoid valve 181 enables precise control of the refrigerant flow path. By operating the first solenoid valve 181, it is possible to flexibly control whether the refrigerant enters the first expansion valve 182, and further control whether the refrigerant enters the second flow path of the plate heat exchanger 12, realizing the optimized management of the system fluid path.

[0102] The valve island assembly 1 integrates the interfaces of the solenoid valve and the expansion valve on the valve island body 11 and realizes the functional connection between them through internal connection. This design improves the integration and compactness of the system, reduces the number of independent components in the system, and makes the entire valve island assembly 1 more compact, easy to install and maintain.

[0103] According to an embodiment of the present invention, the third plate heat exchanger interface 143 and the second expansion valve interface 152 that communicate with each other are formed on the first valve block 131. The second expansion valve interface 152 is connected to the outlet of the first expansion valve 182; the third plate heat exchanger interface 143 is connected to the second flow channel of the plate heat exchanger 12.

[0104] As Figures 1 - 9As shown, on the first valve block 131, there are provided a third interface 143 of the plate heat exchanger and a second expansion valve interface 152 that communicate with each other. Among them, the second expansion valve interface 152 communicates with the outlet of the first expansion valve 182. The refrigerant that has passed through the first expansion valve 182 can flow back to the valve island body 11 through the second expansion valve interface 152 and flow towards the third interface 143 of the plate heat exchanger. Moreover, the third interface of the plate heat exchanger 12 communicates with the second flow channel of the plate heat exchanger 12. Therefore, under the guidance of the third interface 143 of the plate heat exchanger, the refrigerant can enter the second flow channel of the plate heat exchanger 12 to exchange heat with the refrigerant in the first flow channel of the plate heat exchanger 12. By providing the third interface 143 of the plate heat exchanger and the second expansion valve interface 152 that communicate with each other on the first valve block 131, and the second expansion valve interface 152 communicates with the outlet of the first expansion valve 182, this design allows the refrigerant, after passing through the first expansion valve 182, to flow into the third interface 143 of the plate heat exchanger through the second expansion valve interface 152, and then enter the second flow channel of the plate heat exchanger 12, enhancing the flexibility of the heat exchange process, enabling the system to adjust the flow path and heat exchange method of the refrigerant according to actual needs. Since the third interface 143 of the plate heat exchanger directly communicates with the second flow channel of the plate heat exchanger 12, the refrigerant can enter the heat exchange flow channel more directly for heat exchange, reducing the energy loss during the flow of the refrigerant, contributing to optimizing the heat exchange efficiency and improving the overall performance of the system.

[0105] Integrating the third interface 143 of the plate heat exchanger and the second expansion valve interface 152 on the first valve block 131 and achieving their communication through internal connection without the need to set up additional pipelines simplifies the structure of the air-conditioning system 2 and improves the compactness of the structure of the air-conditioning system 2.

[0106] According to an embodiment of the present invention, the first diversion port 145, the second expansion valve interface 152, the first solenoid valve interface 155, and the first expansion valve interface 151 are all open towards one side of the valve island body 11. By making the first diversion port 145, the second expansion valve interface 152, the first solenoid valve interface 155, and the first expansion valve interface 151 all open towards one side of the valve island body 11, these key interfaces are made more accessible and operable during installation and maintenance. Installers or maintenance personnel can conveniently connect or disconnect various pipelines and components from the same side of the valve island body 11 without having to switch on multiple faces of the valve island assembly 1, thereby improving work efficiency.

[0107] Making the above-mentioned multiple interfaces open towards one side of the valve island body 11 helps to optimize the space utilization of the valve island assembly 1 in the air-conditioning system 2, enabling the valve island assembly 1 to be installed more compactly in the air-conditioning system 2, leaving more space for other components or systems, and improving the integration degree of the entire air-conditioning system 2.

[0108] According to an embodiment of the present invention, the third interface 143 of the plate heat exchanger is disposed on the other surface of the first valve block 131 and is adjacent to the second interface 142 of the plate heat exchanger. As Figures 1 - 9 shown, disposing the third interface 143 of the plate heat exchanger on the other surface of the first valve block 131 and adjacent to the second interface 142 of the plate heat exchanger optimizes the spatial layout of the valve island assembly 1. By centrally arranging the interfaces related to the plate heat exchanger 12 on the valve island body 11 on the same side or adjacent positions of the valve block, the entire valve island assembly 1 becomes more compact, which helps to reduce the overall volume of the air-conditioning system 2. Moreover, since the third interface 143 of the plate heat exchanger and the second interface 142 of the plate heat exchanger are adjacent to each other, installers can more quickly connect and assemble the multiple interfaces on the plate heat exchanger 12 with the corresponding valve island interfaces during assembly, improving the assembly efficiency.

[0109] According to an embodiment of the present invention, a fourth interface 144 of the plate heat exchanger is formed on the valve island body 11 and is adapted to communicate with the second flow path outlet of the plate heat exchanger 12; an enthalpy-increasing pipe outlet 147 that is internally connected to the fourth interface 144 of the plate heat exchanger is formed on the valve island body 11, and the enthalpy-increasing pipe outlet 147 is adapted to be connected to the enthalpy-increasing port of the compressor 202. By providing the fourth interface 144 of the plate heat exchanger and the enthalpy-increasing pipe outlet 147 that is internally connected thereto on the valve island body 11, the valve island assembly 1 directly connects the second flow path outlet of the plate heat exchanger 12 with the enthalpy-increasing port of the compressor 202, realizing the integration of the enthalpy-increasing function of the valve island assembly 1, so that the valve island assembly 1 can not only control the conventional flow path of the refrigerant, but also support the enthalpy-increasing operation of the compressor 202, improving the energy efficiency and performance of the air-conditioning system 2. Integrating the enthalpy-increasing pipe outlet 147 on the valve island body 11 reduces the additional connecting components and pipelines in the system, simplifies the structure of the system, not only reduces the complexity and cost of the system, but also improves the reliability and stability of the system, and reduces the potential leakage points and failure risks.

[0110] In some embodiments, the fourth interface 144 of the plate heat exchanger can also be directly connected to the enthalpy-increasing pipe. At this time, the refrigerant in the second flow path of the plate heat exchanger 12 flows out from the fourth interface 144 of the plate heat exchanger and directly returns to the compressor 202 through the enthalpy-increasing pipe.

[0111] According to an embodiment of the present invention, the enthalpy-increasing pipe outlet 147 is provided on the other side surface of the valve island body 11. Setting the enthalpy-increasing pipe outlet 147 on the other side surface of the valve island body 11 optimizes the spatial layout of the valve island assembly 1, enabling the enthalpy-increasing pipe outlet 147 and other interfaces to be distributed on different sides of the valve island body 11, thus avoiding mutual interference between the interfaces. The enthalpy-increasing pipe outlet 147 being provided on the other side surface of the valve island body 11 provides more flexibility and space for pipeline connection. Installers can more conveniently arrange the enthalpy-increasing pipe according to the actual installation environment and requirements. Moreover, the enthalpy-increasing pipe outlet 147 is provided on the other side of the valve island body 11 and is relatively independent of other interfaces or components of the valve island assembly 1. During maintenance or repair, it is easier to access and operate the enthalpy-increasing pipe outlet 147 and its related components, reducing the difficulty and cost of maintenance.

[0112] According to an embodiment of the present invention, a second shunt port 146 is provided on the surface of the first valve block 131 facing the first side edge, and the second shunt port 146 is adapted to be connected to the refrigerant radiator. As Figures 1 - 9 shown, a second shunt port 146 is provided on the surface of the first valve block 131 facing the first side edge. The refrigerant flowing out of the first flow path of the plate heat exchanger 12 can flow towards the second shunt port 146 and, under the guidance of the second shunt port 146, flow into the refrigerant radiator to facilitate the cooling of the electronic control. By providing the second shunt port 146 at a specific position on the first valve block 131 and connecting the second shunt port 146 to the refrigerant radiator (for electronic control cooling), targeted cooling of the electronic control components is achieved. During the operation of the air conditioning system 2, electronic control components (such as circuit boards, sensors, etc.) are prone to performance degradation or damage due to high temperature.

[0113] At this time, the second shunt port 146 can shunt a part of the refrigerant flowing out of the first flow path of the plate heat exchanger 12 and act on the refrigerant radiator to facilitate the cooling of the electronic control components, effectively reducing the temperature of the electronic control area, ensuring the stable operation of the air conditioning system 2, and extending the service life of the components.

[0114] According to an embodiment of the present invention, the other of the two valve blocks is configured as a second valve block 132. A second indoor heat exchanger interface 158 and a refrigerant heat dissipation inlet 156 are formed on the surface of the second valve block 132 facing the first side edge, and the refrigerant heat dissipation inlet 156 is communicated with the refrigerant radiator.

[0115] The other of the two valve blocks is the second valve block 132. The surface of the second valve block 132 facing the first side edge is formed with a second indoor heat exchanger interface 158 and a refrigerant heat dissipation inlet 156. Designing the second indoor heat exchanger interface 158 and the refrigerant heat dissipation inlet 156 on the second valve block 132 enables the valve island assembly 1 to achieve modularization and integration of functions. Furthermore, it makes the layout of the air-conditioning system 2 clearer, reduces the complexity of multiple pipeline connections and potential leakage risks in the traditional air-conditioning system. The refrigerant heat dissipation inlet 156 is directly connected to the refrigerant radiator, simplifying the flow path of the refrigerant from the indoor heat exchanger to the radiator, reducing the flow resistance of the refrigerant in the system, improving the circulation efficiency of the refrigerant, and thus helping to improve the energy efficiency ratio of the entire air-conditioning system 2.

[0116] As Figures 1 - 9 shown, the second indoor heat exchanger interface 158 and the refrigerant heat dissipation inlet 156 are provided on the second valve block 132. The refrigerant can enter the indoor heat exchanger through the second indoor heat exchanger interface 158 and exchange heat with the indoor air, and then return to the valve island body 11 from the first indoor heat exchanger interface 148 for recycling. The refrigerant that enters the refrigerant radiator from the second diversion port 146 can return to the valve island body 11 through the refrigerant heat dissipation inlet 156 for recycling.

[0117] According to an embodiment of the present invention, the valve island assembly 1 further includes: a second expansion valve 183. The second expansion valve 183 is disposed on one side surface of the valve island body 11. The second expansion valve 183 is provided with a second expansion valve 183 inlet and a second expansion valve 183 outlet. Wherein, a third expansion valve interface 153 is provided at the top of the second valve block 132. The third expansion valve interface 153 communicates with the refrigerant heat dissipation inlet 156 inside the first valve block 131, and the third expansion valve interface 153 communicates with the second expansion valve 183 inlet.

[0118] As Figures 1 - 9 shown, a third expansion valve interface 153 is provided at the top of the second valve body, and the third expansion valve interface 153 communicates with the refrigerant heat dissipation inlet 156 inside the first valve block 131. Therefore, the refrigerant in the refrigerant radiator can flow to the third expansion valve interface 153 after returning to the valve island through the refrigerant heat dissipation inlet 156. The third expansion valve interface 153 communicates with the inlet of the second expansion valve 183. Therefore, when the second expansion valve 183 is opened, the refrigerant at the position of the third expansion valve interface 153 can flow into the second expansion valve 183 and flow to other positions or structures under the control of the second expansion valve 183.

[0119] The second expansion valve 183 is disposed on the valve island body 11, and the inlet of the second expansion valve 183 is connected to the third expansion valve interface 153 at the top of the second valve block 132, achieving precise control of the refrigerant flow rate entering the refrigerant heat dissipation inlet 156.

[0120] The third expansion valve interface 153 is directly integrated on the valve island body 11 and is communicated with the refrigerant heat dissipation inlet 156 through an internal communication mode, reducing external pipeline connections, improving the compactness of the structure of the valve island assembly 1, and reducing the complexity and cost of the air conditioning system 2.

[0121] According to an embodiment of the present invention, one of the plurality of valve island interfaces is configured as a fourth expansion valve interface 154, and an outdoor heat exchanger first interface 157 communicated with the fourth expansion valve interface 154 is formed on the valve island body 11; the outlet of the second expansion valve 183 is communicated with the fourth expansion valve interface 154, and the outdoor heat exchanger first interface 157 is adapted to be communicated with an outdoor heat exchanger.

[0122] As Figures 1 - 9 shown, a fourth expansion valve interface 154 is further provided on the second valve block 132. The fourth expansion valve interface 154 is communicated with the outlet of the second expansion valve 183. The refrigerant in the second expansion valve 183 can flow into the valve island through the fourth expansion valve interface 154. Moreover, the fourth expansion valve interface 154 is communicated with the outdoor heat exchanger first interface 157. Therefore, the refrigerant flowing into the valve island through the fourth expansion valve interface 154 can flow to the outdoor heat exchanger first interface 157 and finally flow into the outdoor heat exchanger to exchange heat with outdoor air. By communicating the outlet of the second expansion valve 183 with the fourth expansion valve interface 154 and further connecting it with the outdoor heat exchanger first interface 157, the valve island assembly 1 optimizes the flow path of the refrigerant from the expansion valve to the outdoor heat exchanger, reduces the pressure loss and energy waste during the flow of the refrigerant, ensures efficient heat exchange of the refrigerant in the outdoor heat exchanger, and thus improves the energy efficiency ratio and the refrigeration / heating efficiency of the entire air conditioning system 2.

[0123] Integrating the fourth expansion valve interface 154 and the outdoor heat exchanger first interface 157 on the valve island body 11 reduces the additional connection components and pipelines in the system, making the system layout more compact and concise. It not only reduces the cost and complexity of the system, but also improves the reliability and stability of the system, reducing potential leakage points and failure risks. The integrated interface design makes the installation process more simple and fast, reducing the installation time and cost. At the same time, during the maintenance process, maintenance personnel can more easily access and check these key interfaces and components, reducing the difficulty and cost of maintenance. In addition, due to the clear interface layout, it is also convenient for fault troubleshooting and repair.

[0124] According to an embodiment of the present invention, a filter is provided inside the first interface 157 of the outdoor heat exchanger. By providing a filter inside the first interface 157 of the outdoor heat exchanger, impurities, particulate matters or pollutants that may be carried in the refrigerant can be effectively intercepted, improving the cleanliness of the refrigerant entering the outdoor heat exchanger, preventing blockage or corrosion of the internal pipes of the heat exchanger by impurities, thereby extending the service life of the outdoor heat exchanger and improving the reliability of the entire air conditioning system 2.

[0125] According to an embodiment of the present invention, the valve island body 11 is provided with a third side edge opposite to the first side edge, and the first interface 157 of the outdoor heat exchanger is disposed on the third side edge. By providing a third side edge opposite to the first side edge on the valve island body 11 and disposing the first interface 157 of the outdoor heat exchanger on this third side edge, the spatial layout of the valve island assembly 1 is optimized. The first interface 157 of the outdoor heat exchanger is relatively independent of other interfaces (such as the enthalpy-increasing pipe outlet 147, the second shunt port 146, etc.) in terms of physical position, avoiding mutual interference between the interfaces and improving the accessibility of the interfaces and the convenience of operation.

[0126] According to an embodiment of the present invention, the valve island assembly 1 further includes: a four-way valve 103, the four-way valve 103 is disposed on one side surface of the valve island body 11 and has a main interface, an E interface, an S interface and a C interface that can be selectively communicated with each other, the main interface is adapted to connect to the outlet of the compressor 202, and the E interface, the S interface and the C interface are respectively communicated with corresponding valve island interfaces.

[0127] Integrating the four-way valve 103 on the valve island body 11 enables the valve island assembly 1 to flexibly switch between the refrigeration and heating modes. The main interface of the four-way valve 103 is connected to the outlet of the compressor 202, while the E interface, the S interface and the C interface are respectively communicated with the corresponding interfaces on the valve island, so that the refrigerant flow direction can be adjusted according to the system requirements. In the refrigeration mode, the refrigerant flows along a specific path to absorb indoor heat and discharge it outdoors; in the heating mode, the refrigerant flow direction is reversed to absorb outdoor heat and release it indoors, thereby meeting the usage requirements in different seasons and environments.

[0128] In some embodiments, the four-way valve 103 can be integrated on the valve island body 11, reducing the number of additional connection components and pipelines in the system, simplifying the system structure, which can not only reduce the cost and complexity of the system, but also improve the reliability and stability of the system.

[0129] According to an embodiment of the present invention, the valve island body 11 is provided with a fourth side edge opposite to the second side edge, the fourth side edge is provided with a second interface 161 of the outdoor heat exchanger, and the second interface 161 of the outdoor heat exchanger is adapted to communicate with the outdoor heat exchanger; one of the plurality of valve island interfaces is configured as a four-way valve C pipe interface 164, and the four-way valve C pipe interface 164 is internally communicated with the second interface 161 of the outdoor heat exchanger inside the valve island.

[0130] As shown Figures 1 - 9 in the figure, the outdoor heat exchanger second interface 161 is provided on the valve island body 11. The outdoor heat exchanger second interface 161 is adapted to communicate with the outdoor heat exchanger. The refrigerant in the outdoor heat exchanger can flow back to the valve island through the outdoor heat exchanger second interface 161 after exchanging heat with the outdoor air. The four-way valve C pipe interface 164 is communicated with the outdoor heat exchanger second interface 161 inside the valve island. Therefore, the refrigerant flowing back to the valve island through the outdoor heat exchanger second interface 161 can flow into the four-way valve 103 through the four-way valve C pipe interface 164 and flow to other structures under the guidance of the four-way valve 103. By providing the outdoor heat exchanger second interface 161 on the fourth side edge of the valve island body 11 and communicating it with the C pipe interface of the four-way valve 103 inside the valve island, the flow path of the refrigerant between the valve island assembly 1 and the outdoor heat exchanger is optimized, the complexity of the external pipeline is reduced, the refrigerant flow is made smoother, the pressure loss and energy consumption are reduced, and at the same time, the overall compactness and aesthetics of the system are improved. Since the outdoor heat exchanger second interface 161 and the four-way valve C pipe interface 164 are communicated inside the valve island, there is no need for complex pipeline connection outside the valve island, which improves the compactness of the valve island assembly 1.

[0131] According to an embodiment of the present invention, one of the multiple valve island interfaces is configured as the four-way valve S pipe interface 163. The four-way valve S pipe interface 163 penetrates the valve island body 11 and is adapted to communicate with the return air port of the compressor 202. The penetrating design of the four-way valve S pipe interface 163 makes the connection between the valve island assembly 1 and the return air port of the compressor 202 more direct and simple. Without additional pipeline connectors or complex installation steps, the smooth return of the refrigerant can be realized, which not only reduces the manufacturing cost of the system, but also improves the installation efficiency and reduces the installation time and labor cost. The direct communication between the four-way valve S pipe interface 163 and the return air port of the compressor 202 also reduces the leakage risk and external interference of the refrigerant during the return process.

[0132] The four-way valve S pipe interface 163 penetrates the valve island body 11, so that the connection between the four-way valve S pipe interface 163 and the compressor 202 is located on the other surface of the valve island body 11, which can avoid interference with other valve island interfaces on the valve island, make full use of the space of the valve island, and improve the compactness of the structure of the valve island assembly 1.

[0133] According to an embodiment of the present invention, on the other side of the valve island body 11, a first interface of the gas-liquid separator and a second interface of the gas-liquid separator are provided and communicated with each other inside the valve island body 11; wherein, the first interface of the gas-liquid separator is adapted to be communicated with the outlet of the gas-liquid separator, and the second interface of the gas-liquid separator is adapted to be communicated with the suction port of the compressor 202. By providing the first interface of the gas-liquid separator and the second interface of the gas-liquid separator that are communicated with each other inside the valve island body 11, the valve island assembly 1 realizes a direct and efficient connection between the gas-liquid separator and the suction port of the compressor 202. The gas-liquid separator can remove the liquid components in the refrigerant, ensuring that only gaseous refrigerant enters the compressor 202, thereby improving the quality of the refrigerant, reducing the risk of liquid hammer caused by the compressor 202 sucking liquid refrigerant, and extending the service life of the compressor 202. Integrating the interfaces of the gas-liquid separator on the valve island body 11 reduces the additional connection components and pipelines in the system, making the system layout more compact and concise. This not only reduces the cost and complexity of the system, but also improves the reliability and stability of the system, and reduces potential leakage points and failure risks. The first interface of the gas-liquid separator is communicated with the outlet of the gas-liquid separator, and the second interface of the gas-liquid separator is communicated with the suction port of the compressor 202, optimizing the path of the refrigerant flowing back from the gas-liquid separator to the compressor 202, reducing the pressure loss and energy consumption of the refrigerant during the reflux process, improving the efficiency of the refrigerant reflux, and thus contributing to improving the performance of the entire air-conditioning system 2.

[0134] According to an embodiment of the present invention, one of the multiple valve island interfaces is configured as a four-way valve E-tube interface 162, and the four-way valve E-tube interface 162 is communicated with the second indoor heat exchanger interface 158 inside the valve island body 11. The design of internal communication reduces the unnecessary pipeline length and the number of connection points, not only reducing the complexity and cost of the system, but also reducing the risk of system failure caused by pipeline aging, loosening or leakage, and improving the reliability and stability of the system. By communicating the four-way valve E-tube interface 162 with the second indoor heat exchanger interface 158, the refrigerant in the four-way valve 103 can flow to the second indoor heat exchanger interface 158 under the control of the four-way valve 103 and flow into the indoor heat exchanger through the second indoor heat exchanger interface 158 for heat exchange to realize the refrigeration or heating function of the air-conditioning system 2.

[0135] According to an embodiment of the present invention, the E interface, the S interface, and the C interface are respectively communicated with the four-way valve E-tube interface 162, the four-way valve S-tube interface 163, and the four-way valve C-tube interface 164 in a one-to-one correspondence; wherein, the four-way valve E-tube interface 162, the four-way valve S-tube interface 163, and the four-way valve C-tube interface 164 are located on the same straight line. As Figures 1 - 9As shown, the E - pipe interface 162, S - pipe interface 163, and C - pipe interface 164 of the four - way valve are located on the same straight line, making the layout of the interfaces of the four - way valve 103 on the valve island body 11 more compact. When installers make pipeline connections, they can operate more intuitively and conveniently without complex pipeline adjustment and fixation. This not only reduces the installation difficulty but also reduces the installation time and labor costs, improving the installation efficiency. The interface layout on the same straight line enables maintenance personnel to more easily access and check these interfaces and their connection status during system maintenance or repair.

[0136] The E - interface, S - interface, and C - interface are respectively in one - to - one correspondence and communication with the E - pipe interface 162, S - pipe interface 163, and C - pipe interface 164 of the four - way valve, enabling the four - way valve 103 to control the flow of refrigerant within the valve island to facilitate the realization of the refrigeration and heating functions of the air - conditioning system 2.

[0137] According to an embodiment of the present invention, the plane where the E - pipe interface 162, S - pipe interface 163, and C - pipe interface 164 of the four - way valve are located is the first plane 171; the plane where the first indoor heat - exchanger interface 148 and the second indoor heat - exchanger interface 158 are located is the second plane 172, and the first plane 171 and the second plane 172 are stagger - arranged in the thickness direction of the valve island body 11.

[0138] As Figures 1 - 9 shown, by setting the plane where the E - pipe interface 162, S - pipe interface 163, and C - pipe interface 164 of the four - way valve are located as the first plane 171, and the plane where the first indoor heat - exchanger interface 148 and the second indoor heat - exchanger interface 158 are located as the second plane 172, and the first plane 171 and the second plane 172 are stagger - arranged in the thickness direction of the valve island body 11, it can be simply understood that in the thickness direction of the valve island body 11, the height of the first plane 171 is not the same as the height of the second plane 172, that is: the three interfaces (E - pipe interface 162, S - pipe interface 163, C - pipe interface 164) of the four - way valve 103 on the valve island assembly 1 and the two interfaces (first indoor heat - exchanger interface 148 and second indoor heat - exchanger interface 158) of the indoor heat - exchanger on the valve island assembly 1 are not at the same height. This can avoid mutual interference between different interfaces, effectively utilize the three - dimensional space of the valve island body 11, optimize the spatial layout of the valve island interfaces, reduce the planar occupation area between the valve island interfaces, enabling the valve island assembly 1 to achieve higher spatial compactness while maintaining functional integrity, which helps to save installation space and adapt to more compact installation environments. Since the first plane 171 and the second plane 172 are staggered in the thickness direction, different valve island interfaces can be arranged more orderly, reducing the interference between different valve island interfaces and improving the reliability and stability of the system.

[0139] According to one embodiment of the present invention, it also includes: a first expansion valve 182 and a second expansion valve 183, the first expansion valve 182 and the second expansion valve 183 are respectively connected to the valve island interface to be arranged on one side surface of the valve island body 11; wherein the first expansion valve 182 and the second expansion valve 183 are respectively located between the first plane 171 and the second plane 172.

[0140] The valve island assembly 1 arranges the first expansion valve 182 and the second expansion valve 183 on one side surface of the valve island body 11, and is located between the first plane 171 and the second plane 172, that is: in the thickness direction of the valve island body 11, the height of the first expansion valve 182 and the second expansion valve 183 is located between the first plane 171 and the second plane 172, which can avoid the first expansion valve 182 and the second expansion valve 183 from interfering with other valve island interfaces during assembly, and the different heights in the thickness direction of the valve island body 11 effectively utilize the space of the valve island body 11, which can improve the compactness of the structure of the valve island body 11, reduce the overall volume of the air-conditioning system 2, and make the entire air-conditioning system 2 more compact and easy to install and maintain.

[0141] In some embodiments, when the plate heat exchanger 12 is placed vertically, the plane where the second interface 142 of the plate heat exchanger and the third interface 143 of the plate heat exchanger are located can be located on the side of the first plane 171 away from the second plane 172. It can be simply understood as: in the thickness direction of the valve island body 11, the height of the second interface 142 of the plate heat exchanger and the third interface 143 of the plate heat exchanger are higher than the first plane 171, which can avoid interference between the second interface 142 of the plate heat exchanger and the plate heat exchanger 12 and other valve island interfaces, and can effectively utilize the space of the valve island assembly 1 and improve the compactness of the structure of the valve island assembly 1.

[0142] The air conditioning system 2 according to the present invention will be briefly described below.

[0143] The air-conditioning system 2 according to the present invention includes the valve island assembly 1 in the above-mentioned embodiment. Since the air-conditioning system 2 according to the present invention is provided with the valve island assembly 1 in the above-mentioned embodiment, the valve island assembly 1 integrates multiple valve island interfaces on the valve island body 11, and arranges the valve body and the plate heat exchanger 12 on the valve island body 11, thereby reducing the space occupied by the valve island assembly 1 in the air-conditioning system 2, thereby improving the compactness of the structure of the air-conditioning system 2, reducing the overall volume of the air-conditioning system 2, and facilitating the layout of the air-conditioning system 2.

[0144] In some embodiments, the flow path of the refrigerant in the air conditioning system 2 can be briefly summarized as follows: After flowing out of the compressor 202, the refrigerant can flow into the oil separator 203, and after passing through the oil separator 203, it flows towards the four-way valve 103. Under the control of the four-way valve 103, the refrigerant enters the valve island body 11 through the four-way valve E pipe interface 162, and flows through the internal communication flow path to the second interface of the indoor heat exchanger, and then enters the indoor heat exchanger for heat exchange. After heat exchange, the refrigerant flows back to the valve island body 11 from the first interface of the indoor heat exchanger, and flows along an internal communication flow path in the valve island body 11 to the first interface 141 of the plate heat exchanger and enters the first flow path in the plate heat exchanger 12, and then flows into the valve island body 11 through the second interface 142 of the plate heat exchanger. At this time, the refrigerant is split: a part of the refrigerant flows into the first solenoid valve 181 through the first split port 145, flows through the first solenoid valve 181 to the first interface of the battery valve, and then flows through an internal communication flow path to the first expansion valve interface 151 and then enters the first expansion valve 182. The first expansion valve 182 guides a part of the refrigerant into the second expansion valve interface, and under the guidance of another internal communication flow path, it flows into the second flow path in the plate heat exchanger 12 through the third interface 143 of the plate heat exchanger to exchange heat with the refrigerant in the first flow path. After heat exchange, the refrigerant can flow back to the valve island through the fourth interface 144 of the plate heat exchanger and flow back to the compressor 202 through the enthalpy-increasing pipe outlet 147 under the guidance of the internal communication flow path; another part of the refrigerant flows to the refrigerant radiator through the second split port 146 to dissipate heat from the electronic control. After heat dissipation, the refrigerant flows back to the valve island through the refrigerant heat dissipation inlet 156 and flows into the second expansion valve 183 through the third expansion valve interface 153 under the guidance of the internal communication flow path. The second expansion valve 183 guides another part of the refrigerant to flow back to the valve island body 11 through the fourth expansion valve interface 154, and under the guidance of an internal communication flow path, it flows into the outdoor heat exchanger through the filter in the first interface 157 of the outdoor heat exchanger for heat exchange. After heat exchange, the refrigerant flows back to the valve island body 11 through the second interface 161 of the outdoor heat exchanger and flows into the four-way valve 103 through an internal communication flow path and the four-way valve C pipe interface 164, and then flows into the gas-liquid separator through the four-way valve S pipe interface 163 under the control of the four-way valve 103 and then flows back to the compressor 202.

[0145] In some embodiments, the air conditioning system 2 of the present invention can be used for traditional indoor and outdoor air conditioners, and can also be used for vehicles or other devices that require heat dissipation.

[0146] In summary, the valve island assembly 1 is provided with a valve island body 11, on which a plurality of valve island interfaces are integrated. At least two valve island interfaces are connected through internal communication channels. A plate heat exchanger 12 and a valve body are provided on the valve island body 11.
