[0040] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0041] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

"Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0043] In related technologies, air conditioning systems include valve island assemblies, which consist of multiple valve bodies and corresponding pipes and interfaces. In some existing technologies, the multiple valve bodies of the valve island assembly are concentrated in a small space, resulting in some valve bodies being obstructed and limited maintenance space, making maintenance operations difficult.

[0044] The following is for reference. Figures 1-7 The valve island assembly 1 according to an embodiment of the present utility model is described.

[0045] like Figures 1-7 As shown, the valve island assembly 1 according to this utility model includes: a valve island body 10, a first valve module 20, and a second valve module 30. The valve island body 10 forms a first interface and a second interface. The first valve module 20 is connected to the first interface and located on one side of the valve island body 10 in a first direction. The second valve module 30 is connected to the second interface. The first valve module 20 and the second valve module 30 are arranged alternately at least in the first direction and / or on a first plane, where the first plane intersects the first direction. Specifically, the valve island body 10 integrates multiple media flow paths and corresponding interfaces. The first interface formed by the valve island body 10 is adapted to communicate with the first valve module 20, and the second interface is adapted to communicate with the second valve module 30, thereby realizing the integration of multiple valve bodies and corresponding pipelines and interfaces. Further, the first valve module 20 can be a collection of at least one valve body, and the second valve module 30 can also be a collection of at least one valve body.

[0046] Here, the first interface and the second interface can be located on opposite sides of the valve island body 10 in the first direction, or they can be located on the same side of the valve island body 10 in the first direction. The setting position of the first valve module 20 and the second valve module 30 relative to the valve island body 10 can be determined according to the setting position of the corresponding interface on the valve island body 10. For example, if the first interface and the second interface are located on opposite sides of the valve island body 10 in the first direction, then the first valve module 20 is located on one side of the valve island body 10 in the first direction, and the second valve module 30 is located on the other side of the valve island body 10 in the first direction. Alternatively, if the first interface and the second interface are located on the same side of the valve island body 10 in the first direction, then the first valve module 20 and the second valve module 30 are located on the same side of the valve island body 10 in the first direction. This avoids bending of the pipeline connecting the valve body and the corresponding interface, reduces the pipeline length, and increases the pipeline strength, thereby improving the working reliability of the valve island assembly 1. It can also reduce the material used in the pipeline and save costs.

[0047] Furthermore, the first valve module 20 and the second valve module 30 can be designed to be staggered in the first direction, so that the valve bodies included in the first valve module 20 and the second valve module 30 can be staggered in the first direction. Alternatively, the first valve module 20 and the second valve module 30 can be designed to be staggered in the first plane, so that the valve bodies included in the first valve module 20 and the second valve module 30 can be staggered in the first plane. Or, the first valve module 20 and the second valve module 30 can be staggered in both the first direction and the first plane, so that the valve bodies included in the first valve module 20 and the second valve module 30 can be staggered in both the first direction and the first plane, respectively.

[0048] According to the present invention, the valve island assembly 1, by designing the relative positions of the first valve module 20 and the second valve module 30, can avoid the first valve module 20 and the second valve module 30 from blocking each other, thereby improving the convenience of maintenance and installation of each valve body. This allows for convenient maintenance operations on each valve body while keeping the valve island assembly 1 in a small volume.

[0049] According to some embodiments of this utility model, such as Figure 3 , Figure 4 As shown, the first plane is orthogonal to the first direction, and the projection of the first valve module 20 on the first plane is separate from the projection of the second valve module 30 on the first plane. Specifically, the projection of the first valve module 20 in the first direction falls on the first plane, and the projection of the second valve module 30 in the first direction also falls on the first plane. In these embodiments, the first valve module 20 and the second valve module 30 are staggered on the first plane so that the valve bodies included in the first valve module 20 and the valve bodies included in the second valve module 30 can be staggered on the first plane.

[0050] Furthermore, the projection of the first valve module 20 onto the first plane is separate from the projection of the second valve module 30 onto the first plane. In other words, the projections of the first valve module 20 and the second valve module 30 in the first direction do not intersect. Therefore, the first valve module 20 and the second valve module 30 will not obstruct each other in the first direction. This facilitates maintenance personnel in performing maintenance operations on the first valve module 20 or the second valve module 30 from the first direction within a limited space, and also facilitates maintenance personnel in performing maintenance operations on the first valve module 20 or the second valve module 30 from other directions within a limited space. The valve island assembly 1 can be used within an air conditioning unit 1000, which generally has a maintenance surface. The valve island assembly 1 can face the maintenance surface, and the facing direction of the valve island assembly 1 can be the first direction or other directions that expose the first valve module 20 and the second valve module 30.

[0051] It is worth mentioning that, ideally, such as Figure 5 , Figure 7 As shown, the projections of the first valve module 20 and the second valve module 30 on the first plane are separate to avoid them obstructing each other. However, in practical applications, there are cases where the projections of the first valve module 20 and the second valve module 30 on the first plane partially overlap due to the larger volume of the valve body portion of the first valve module 20, or vice versa. Even if the projections of the first valve module 20 and the second valve module 30 on the first plane partially overlap due to the larger volume of the valve body portion of the second valve module 30, this situation is still within the scope of protection of this utility model.

[0052] Furthermore, the valve bodies included in the first valve module 20 can be concentrated in one area or distributed. Similarly, the valve bodies included in the second valve module 30 can also be concentrated in one area or distributed. Additionally, the valve bodies included in the first valve module 20 can be distributed around at least a portion of the outer periphery of the second valve module 30, or the valve bodies included in the second valve module 30 can be distributed around at least a portion of the outer periphery of the first valve module 20. Alternatively, the valve bodies included in the first valve module 20 can be concentrated on either side of the second valve module 30, or the valve bodies included in the second valve module 30 can be concentrated on either side of the first valve module 20. Furthermore, the valve bodies included in the first valve module 20 and the valve bodies included in the second valve module 30 can be arranged alternately, and the design can be tailored to the specific circumstances.

[0053] According to some embodiments of this utility model, such as Figure 3 As shown, the first valve module 20 includes multiple first valve bodies, and the projections of these multiple first valve bodies onto the first plane are located on the same side of the projection of the second valve module 30 onto the first plane. Specifically, the multiple first valve bodies included in the first valve module 20 are concentrated on the same side of the second valve module 30, so that the projections of the multiple first valve bodies onto the first plane are located on the same side of the projection of the second valve module 30 onto the first plane. This saves space occupied by the first valve module 20, miniaturizes the valve island assembly 1, facilitates the arrangement of electrical control wiring harnesses, and improves manufacturing efficiency. It is worth mentioning that... Figure 3 The distribution of the multiple first valve bodies shown is one possible implementation. The distribution of these first valve bodies can be designed according to actual needs and is not limited to that shown in the figure.

[0054] In some embodiments, the second valve module 30 includes a second valve body extending along a second direction that intersects with a first direction, and a plurality of first valve bodies are centrally arranged on the same side of the second valve body in the second direction.

[0055] According to some embodiments of this utility model, such as Figure 2 As shown, the second valve module 30 is located on the side of the first valve module 20 away from the valve island body 10 in the first direction. In this case, the first valve module 20 and the second valve module 30 are located on the same side of the valve island body 10 in the first direction, facilitating maintenance operations. Furthermore, the second valve module 30, the first valve module 20, and the valve island body 10 are arranged sequentially in the first direction, and the first valve module 20 and the second valve module 30 are staggered in the first direction, so that the valve bodies included in the first valve module 20 and the second valve module 30 can be staggered in the first direction.

[0056] Furthermore, the first valve module 20 and the second valve module 30 are arranged alternately in the first direction and the first plane, respectively, so that the valve body included in the first valve module 20 and the valve body included in the second valve module 30 can be arranged alternately in the first direction and the first plane, respectively.

[0057] In some embodiments, the first direction is consistent with the height direction.

[0058] According to some embodiments of this utility model, such as Figure 3As shown, the first plane is orthogonal to the first direction. The first valve module 20 includes multiple first valve bodies, and the projections of the multiple first valve bodies on the first plane are separate. Specifically, the projection of the first valve body in the first direction falls on the first plane, and the projections of the multiple first valve bodies on the first plane are separate. That is to say, the projections of the multiple first valve bodies in the first direction do not intersect, and the multiple first valve bodies will not obstruct each other in the first direction. This facilitates maintenance personnel to perform maintenance operations on the multiple first valve bodies from the first direction within a limited space, and also facilitates maintenance personnel to perform maintenance operations on the multiple first valve bodies from other directions within a limited space.

[0059] It is worth mentioning that, ideally, the projections of multiple first valve bodies on the first plane are separate to avoid them obscuring each other. However, in practical applications, there are cases where the projections of at least two first valve bodies on the first plane overlap due to the large size of some first valve body structures. Under the condition that the relative positions of the first valve module 20 and the second valve module 30 are designed to avoid them obscuring each other, the overlapping projections of at least two first valve bodies on the first plane are also within the protection scope of this utility model.

[0060] Furthermore, the multiple first valve bodies can be concentrated in one area or dispersed. The multiple first valve bodies can be dispersed on at least part of the outer periphery of the second valve module 30, or concentrated on any side of the second valve module 30. Alternatively, the multiple first valve bodies can be arranged at intervals with the valve bodies included in the second valve module 30, which can be designed according to the actual situation.

[0061] In some embodiments, such as Figure 3 As shown, at least one of the multiple first valve bodies is configured as an electronic expansion valve 21, a solenoid valve 22, a shut-off valve 23, or a main electronic expansion valve 24. Furthermore, the multiple first valve bodies are centrally located on the same side of the second valve module 30. Further, there are two shut-off valves 23, which are used to control the flow of liquid and gaseous media within the valve island body 10, respectively.

[0062] According to some embodiments of this utility model, such as Figure 3As shown, the valve island body 10 has a length direction and a width direction that are orthogonal to the first direction and to each other. The second valve module 30 includes a second valve body that extends along a second direction, and the second direction intersects the first direction, the length direction, and the width direction of the valve island body 10, respectively. Specifically, the first plane is orthogonal to the first direction, and the second valve body is arranged parallel to the first plane. To reduce the space occupied by the valve island assembly 1, the second valve body can be tilted and arranged on one side of the valve island body 10 in the first direction. At this time, the extension direction of the second valve body intersects the length direction and the width direction of the valve island body 10, which can reduce the space occupied by the second valve body in the length direction and the width direction of the valve island body 10, which is beneficial to the miniaturization of the valve island assembly 1 and expands the application range of the valve island assembly 1.

[0063] In some embodiments, the second valve body is configured as a four-way valve 31.

[0064] According to some embodiments of this utility model, the valve island body 10 includes a flow channel plate and a base plate. A flow channel is formed on one side of the flow channel plate in the thickness direction. A first interface and a second interface, respectively communicating with the flow channel, are also formed on the flow channel plate. The base plate cooperates with the flow channel plate to cover the flow channel, which is suitable for medium flow. The first valve module 20 is located on the side of the flow channel plate away from the base plate. Here, the thickness direction is consistent with the first direction, and the first direction is consistent with the height direction of the valve island assembly 1. The valve island body 10 is installed horizontally, and the flow channels are distributed in the plane of the valve island body 10. The first interface, the second interface, and the flow channels are arranged on the same horizontal plane, which can avoid flow channel intersection and facilitate heat insulation treatment of the flow channels. Furthermore, the flow channel plate is located at the top of the base plate in the height direction. At this time, the first interface and the second interface are also located at the top of the valve island body 10. The opening direction of the first interface and the second interface is upward, which facilitates the pre-positioning when the valve body is welded to the valve island body 10, ensures welding on the same side, and improves production efficiency. The first interface and the second interface are mostly vertical, which facilitates the installation of existing valve bodies, ensures that the valve body is vertical in normal use scenarios, and does not require the addition of connecting pipes to adjust the interface direction.

[0065] Furthermore, the flow channels are centrally located in the valve island body 10, which can reduce the space occupied by the valve island assembly 1 and limit the relative positions of the first valve module 20 and the second valve module 30, so as to make maintenance more convenient while taking into account the miniaturization of the valve island assembly 1.

[0066] According to some embodiments of this utility model, such as Figure 1 , Figure 2As shown, the base plate has a third interface communicating with the flow channel; the valve island body 10 also includes a plate heat exchanger 11, which is disposed on the base plate and has multiple plate heat exchanger interfaces, at least one of which is communicating with the third interface. Specifically, the plate heat exchanger 11 is adapted to exchange heat with the medium in the valve island body 10. Of course, the plate heat exchanger 11 can also exchange heat with other structures outside the valve island assembly 1.

[0067] The following is a brief description of the air conditioning system 100 according to this utility model.

[0068] The air conditioning system 100 according to this utility model includes the valve island assembly 1 described in any of the above embodiments. Since the air conditioning system 100 according to this utility model is provided with the valve island assembly 1 of the above embodiments, the air conditioning system 100 is easy to maintain.

[0069] In some embodiments, the air conditioning system 100 further includes a gas-liquid separator 101 and a compressor 102. The gas-liquid separator 101 is connected to a valve island body 10, and the valve island body 10 is mounted and supported on the gas-liquid separator 101. A plurality of refrigerant piping components are connected to the valve island body 10 and communicate with the compressor 102 and the gas-liquid separator 101 to form a refrigerant circuit.

[0070] In some embodiments, such as Figure 8 As shown, the refrigerant flow path in the air conditioning system 100 can be simply summarized as follows: After flowing out of the compressor 102, the refrigerant flows into the oil separator 103. After passing through the oil separator 103, it flows to the four-way valve 31. Under the control of the four-way valve 31, the refrigerant enters the valve island body 10 through the four-way valve 31, and flows to the indoor heat exchanger through one of the shut-off valves 23. After entering the indoor heat exchanger for heat exchange, the refrigerant flows back to the valve island body 10 through the other shut-off valve 23, and flows along the flow channel in the valve island body 10 to the plate heat exchanger 11 and enters the plate heat exchanger 12. Inside the first compartment, the refrigerant is divided: one part of the refrigerant enters the valve island body 10 after being further throttled by the electronic expansion valve 21. The refrigerant undergoes full heat exchange with the main circuit in the plate heat exchanger 11 and flows back to the compressor 102 under the guidance of the flow channel in the valve island body 10. The other part of the refrigerant flows out through the refrigerant heat dissipation pipe 104 and flows through the main electronic expansion valve 24. Finally, it passes through the filter and enters the outdoor heat exchanger. After the outdoor heat exchanger exchanges heat with the outdoor environment, the refrigerant enters the four-way valve and undergoes gas-liquid separation through the gas-liquid separator 101. Finally, it flows back to the compressor 102.

[0071] The air conditioning device 1000 according to this utility model is briefly described below.

[0072] like Figures 4-7As shown, the air conditioning device 1000 according to this utility model includes the valve island assembly 1 described in any of the above embodiments or the air conditioning system 100 described in the above embodiments, and also includes a housing 2. The housing 2 defines an accommodating space 2a suitable for accommodating the valve island assembly 1. The second valve module 30 is located on the side of the first valve module 20 away from the side plate of the housing 2 or on the side of the first valve module 20 away from the maintenance port of the housing 2. Specifically, the valve island assembly 1 is used inside the housing 2 of the air conditioning device 1000. The housing 2 has a maintenance surface. The valve island assembly 1 can face the maintenance surface. The facing direction of the valve island assembly 1 and the maintenance surface can be a first direction or other directions that can expose the first valve module 20 and the second valve module 30, so as to perform maintenance operations on the first valve module 20 or the second valve module 30.

[0073] The side panels of the enclosure 2 include two side panels or a front panel, which can be opened for maintenance, thus serving as a maintenance surface. Alternatively, a maintenance port can be provided on the enclosure 2, with the first valve module 20 positioned close to the maintenance port and the second valve module positioned away from it. Further, the second valve module 30 is located on the side of the first valve module 20 away from the maintenance port, or the first valve module 20 is located on the side of the second valve module 30 away from the maintenance port, so that the first valve module 20 and the second valve module 30 are staggered in the direction facing the valve island assembly 1 and the maintenance port, ensuring that the first valve module 20 or the second valve module 30 is not obstructed during installation and maintenance, while also facilitating electrical wiring. Even further, such as... Figure 5 , Figure 7 As shown, since the first valve module 20 has multiple first valve bodies and the second valve module 30 has one second valve body, the second valve module 30 is located on the side of the first valve module 20 away from the maintenance port, so that both the first valve module 20 and the second valve module 30 are exposed through the maintenance port, which facilitates maintenance operations by maintenance personnel.

[0074] Since the air conditioning equipment 1000 according to this utility model includes the above-mentioned valve island assembly 1 or the above-mentioned air conditioning system 100, the air conditioning equipment 1000 is easy to maintain.

[0075] In some embodiments, the air conditioning device 1000 may be an outdoor unit of an air conditioner. When the service port of the outdoor unit is located on the front side of the unit, it can be referred to... Figure 4 , Figure 5 For high-altitude operations or scenarios with limited frontal space, please refer to Figure 6 , Figure 7 The maintenance port is located on the right or rear side of the machine, so that maintenance personnel can perform installation and maintenance operations from the right or rear side.

[0076] In summary, the valve island assembly 1 according to this utility model can avoid the first valve module 20 and the second valve module 30 from blocking each other. By designing the relative positions of the first valve module 20 and the second valve module 30, the convenience of maintenance and installation of each valve body is improved. It is possible to facilitate maintenance operations on each valve body while keeping the valve island assembly 1 in a small volume.
