Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0041] In the present invention, unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be understood broadly. For example, they may refer to fixed or detachable connections, or integration; mechanical or electrical connections, or communication; direct or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components.

[0043] Air conditioning systems typically feature valve island assemblies, which are composed of multiple valve bodies, corresponding piping, and interfaces. In some existing technologies, these multiple valve bodies are concentrated within a relatively small space, obstructing some of the valve bodies and limiting maintenance space, making repairs difficult.

[0044] Reference below Figure 1-Figure 7 A valve island assembly 1 according to an embodiment of the present invention is described.

[0045] like Figure 1-Figure 7 As shown, the valve island assembly 1 according to the present invention includes: a valve island body 10, a first valve module 20 and a second valve module 30, wherein the valve island body 10 is formed with a first interface and a second interface; the first valve module 20 is connected to the first interface and is located on one side of the valve island body 10 in the first direction; the second valve module 30 is connected to the second interface; wherein the first valve module 20 and the second valve module 30 are staggered at least in the first direction and / or the first plane, and the first plane intersects with the first direction. Specifically, the valve island body 10 is integrated with multiple medium flow paths and corresponding interfaces, wherein the first interface formed by the valve island body 10 is suitable for communicating with the first valve module 20, and the second interface is suitable for communicating with the second valve module 30, so as to realize the integration of multiple valve bodies and corresponding pipelines and interfaces. Furthermore, 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 respectively located on both sides of the valve island body 10 in the first direction, or on the same side of the valve island body 10 in the first direction. The setting positions 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 positions of the corresponding interfaces on the valve island body 10. For example, the first interface and the second interface are respectively located on both 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, 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, so as to avoid bending of the pipeline connecting the valve body and the corresponding interface, reduce the length of the pipeline, and improve the strength of the pipeline, thereby improving the working reliability of the valve island assembly 1, and 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 valve bodies included in 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 staggered in 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 in the first plane. Alternatively, the first valve module 20 and the second valve module 30 can be staggered in the first direction and the first plane, respectively, 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 in the first direction and the first plane, respectively.

[0048] According to the valve island assembly 1 of the present invention, by designing the relative positions of the first valve module 20 and the second valve module 30, it is possible to avoid the first valve module 20 and the second valve module 30 blocking each other, thereby improving the convenience of maintenance and installation of each valve body, so as to facilitate maintenance operations on each valve body while keeping the valve island assembly 1 in a smaller volume.

[0049] According to some embodiments of the present invention, 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 spaced apart 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 arranged alternately 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 arranged alternately on the first plane.

[0050] Furthermore, the projection of the first valve module 20 on the first plane is separated from the projection of the second valve module 30 on the first plane. That is, the projection of the first valve module 20 in the first direction does not intersect with the projection of the second valve module 30 in the first direction. The first valve module 20 and the second valve module 30 do not block each other in the first direction, making it convenient for maintenance personnel to perform maintenance operations on the first valve module 20 or the second valve module 30 from the first direction within a limited space, and also convenient for maintenance personnel to perform 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 in an air conditioning device 1000. The air conditioning device 1000 generally has a maintenance surface. The valve island assembly 1 can be opposite to the maintenance surface. The direction in which the valve island assembly 1 faces the maintenance surface can be the first direction or other direction that exposes the first valve module 20 and the second valve module 30.

[0051] It is worth mentioning that ideally, Figure 5 、 Figure 7 As shown, the projection of the first valve module 20 on the first plane is separated from the projection of the second valve module 30 on the first plane to prevent the first valve module 20 and the second valve module 30 from blocking each other. However, in actual applications, due to the large structural volume of the valve body portion included in the first valve module 20, the projection of the first valve module 20 on the first plane may partially overlap with the projection of the second valve module 30 on the first plane, or due to the large structural volume of the valve body portion included in the second valve module 30, the projection of the first valve module 20 on the first plane may partially overlap with the projection of the second valve module 30 on the first plane. As long as the relative positions of the first valve module 20 and the second valve module 30 are designed to prevent the first valve module 20 and the second valve module 30 from blocking each other, the situation where the projection of the first valve module 20 on the first plane and the projection of the second valve module 30 on the first plane partially overlap is also within the scope of protection of the present invention.

[0052] Furthermore, the valve bodies included in the first valve module 20 can be concentrated in one area or dispersed. Similarly, the valve bodies included in the second valve module 30 can also be concentrated in one area or dispersed. Furthermore, the valve bodies included in the first valve module 20 can be dispersed around at least part of the periphery of the second valve module 30, or the valve bodies included in the second valve module 30 can be dispersed around at least part of the 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 and distributed on either side of the first valve module 20. Alternatively, the valve bodies included in the first valve module 20 and the valve bodies included in the second valve module 30 can be spaced apart. The design can be made according to actual conditions.

[0053] According to some embodiments of the present invention, Figure 3 As shown, the first valve module 20 includes a plurality of first valve bodies, and the projections of the plurality of first valve bodies on the first plane are located on the same side of the projection of the second valve module 30 on the first plane. Specifically, the plurality of first valve bodies included in the first valve module 20 are concentratedly arranged on the same side of the second valve module 30, so that the projections of the plurality of first valve bodies on the first plane are located on the same side of the projection of the second valve module 30 on the first plane. This can save the space occupied by the first valve module 20, miniaturize the valve island assembly 1, facilitate the arrangement of the electric control harness, and improve production efficiency. It is worth mentioning that Figure 3 The distribution of the multiple first valve bodies shown in the figure is one of the possible implementation plans. 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 intersecting the 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 the present invention, Figure 2 As shown, the second valve module 30 is located on a side of the first valve module 20 that is away from the valve island body 10 in the first direction. At this time, 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 for maintenance personnel. 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 valve bodies included in the second valve module 30 are 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 bodies included in the first valve module 20 and the valve bodies 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 coincides with the height direction.

[0058] According to some embodiments of the present invention, Figure 3As shown, the first plane is orthogonal to the first direction, and the first valve module 20 includes a plurality of first valve bodies, the projections of which on the first plane are spaced apart. Specifically, the projections of the first valve bodies in the first direction fall on the first plane, and the projections of the plurality of first valve bodies on the first plane are spaced apart. In other words, the projections of the plurality of first valve bodies in the first direction do not intersect, and the plurality of first valve bodies do not obstruct each other in the first direction. This facilitates maintenance personnel to perform maintenance operations on the plurality of first valve bodies from the first direction within a limited space, and also facilitates maintenance personnel to perform maintenance operations on the plurality of first valve bodies from other directions within a limited space.

[0059] It is worth mentioning that, ideally, the projections of the multiple first valve bodies on the first plane are separated to avoid the multiple first valve bodies blocking each other. However, in actual applications, there is a situation where the projections of at least two first valve bodies on the first plane partially overlap due to the larger volume 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 the first valve module 20 and the second valve module 30 blocking each other, the situation where the projections of at least two first valve bodies on the first plane partially overlap is also within the scope of protection of the present invention.

[0060] In addition, multiple first valve bodies can be concentrated in one area or dispersed, and multiple first valve bodies can be dispersed on at least part of the periphery of the second valve module 30, or can be concentrated on any side of the second valve module 30. Alternatively, multiple first valve bodies and the valve bodies included in the second valve module 30 can be spaced apart and designed according to actual conditions.

[0061] In some embodiments, 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 stop valve 23, or a main electronic expansion valve 24. Furthermore, the multiple first valve bodies are collectively arranged on the same side of the second valve module 30. Furthermore, two stop valves 23 are configured, one for controlling the flow of liquid and the other for controlling the flow of gaseous media within the valve island body 10.

[0062] According to some embodiments of the present invention, Figure 3As shown, the valve island body 10 has a length direction and a width direction that are respectively orthogonal to the first direction and orthogonal to each other. The second valve module 30 includes a second valve body, which extends along the second direction, and the second direction intersects with the first direction, the length direction, and the width direction of the valve island body 10. 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 to one side of the valve island body 10 in the first direction. In this case, the extension direction of the second valve body intersects with the length direction and the width direction of the valve island body 10, respectively. This 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 conducive to the miniaturization of the valve island assembly 1 and expands the applicable 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 the present invention, 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. The flow channel plate also has a first interface and a second interface that are respectively connected to the flow channel. The base plate and the flow channel plate cooperate to cover the flow channel, and the flow channel is suitable for medium circulation. 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 within 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 cross-flow of the flow channels and facilitate thermal insulation of the flow channels. In addition, 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 is convenient for pre-positioning when the valve body and the valve island body 10 are welded together, ensuring same-side welding and improving production efficiency. The first interface and the second interface are mostly vertical, which is convenient for the installation of the existing valve body, ensuring that the valve body direction is vertical in conventional use scenarios, and there is no need to add a connecting pipe to adjust the interface direction.

[0065] Furthermore, the flow channels are centrally arranged on 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, thereby achieving more convenient maintenance while miniaturizing the valve island assembly 1.

[0066] According to some embodiments of the present invention, Figure 1 、 Figure 2As shown, the base plate is formed with a third interface that communicates with the flow channel. The valve island body 10 also includes a plate heat exchanger 11, which is mounted on the base plate and has multiple plate heat exchanger interfaces, at least one of which communicates with the third interface. Specifically, the plate heat exchanger 11 is adapted to exchange heat with the medium within 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 air conditioning system 100 according to the present invention will be briefly described below.

[0068] The air-conditioning system 100 according to the present invention includes the valve island assembly 1 described in any of the above embodiments. Since the air-conditioning system 100 according to the present invention 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 also includes a gas-liquid separator 101 and a compressor 102. The gas-liquid separator 101 is connected to the valve island body 10. The valve island body 10 is installed and supported on the gas-liquid separator 101. Multiple refrigerant pipeline components are connected to the valve island body 10 and are connected to the compressor 102 and the gas-liquid separator 101 to form a refrigerant circuit.

[0070] In some embodiments, as Figure 8 As shown, the flow path of the refrigerant in the air-conditioning system 100 can be simply summarized as follows: after flowing out of the compressor 102, the refrigerant can flow into the oil-liquid separator 103, and after passing through the oil-liquid 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 stop valves 23, and then enters the indoor heat exchanger for heat exchange. After heat exchange, the refrigerant flows back to the valve island body 10 through the other stop 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 1 1, at this time, the refrigerant is split: a part of the refrigerant is further throttled by the electronic expansion valve 21 and then enters the valve island body 10. The refrigerant undergoes sufficient 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 from the refrigerant heat dissipation pipe 104, flows through the main electronic expansion valve 24, and finally enters the outdoor heat exchanger through the filter. After the outdoor heat exchanger exchanges heat with the outdoor environment, the refrigerant enters the four-way valve and is separated into gas and liquid through the gas-liquid separator 101, and finally flows back to the compressor 102.

[0071] The air conditioning apparatus 1000 according to the present invention will be briefly described below.

[0072] like Figure 4-Figure 7As shown, the air-conditioning equipment 1000 according to the present invention includes the valve island assembly 1 described in any of the above embodiments or includes the air-conditioning system 100 described in the above embodiments, and further includes a housing 2, the interior of which defines a receiving space 2a suitable for accommodating the valve island assembly 1. The second valve module 30 is located on a side of the first valve module 20 away from the side panel of the housing 2 or on a side of the first valve module 20 away from the maintenance port of the housing 2. Specifically, the valve island assembly 1 is used in the housing 2 of the air-conditioning equipment 1000, and the housing 2 has a maintenance surface. The valve island assembly 1 can face the maintenance surface, and the facing direction of the valve island assembly 1 and the maintenance surface can be the first direction or other direction that can expose the first valve module 20 and the second valve module 30, so as to facilitate maintenance operations on the first valve module 20 or the second valve module 30.

[0073] The side panels of the box body 2 include two side panels or a front panel, which can be opened for maintenance. In this case, the side panels or the front panel are constructed as maintenance surfaces; or a maintenance port can also be opened on the box body 2, and the first valve module 20 is arranged close to the maintenance port, and the second valve module is arranged away from the maintenance port. Furthermore, 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 opposite to the valve island assembly 1 and the maintenance port, ensuring that the first valve module 20 or the second valve module 30 is not blocked during installation and maintenance, while facilitating the management of electrical control lines. Furthermore, 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 from the maintenance port, which is convenient for maintenance personnel to perform maintenance operations.

[0074] Since the air conditioning device 1000 according to the present invention includes the valve island assembly 1 or the air conditioning system 100 , the air conditioning device 1000 is easy to maintain.

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

[0076] To sum up, the valve island assembly 1 according to the present invention can avoid the first valve module 20 and the second valve module 30 from blocking each other.
