[0002] In related technologies, the throttle valve is a crucial component of the air conditioning system. However, improper installation of the throttle valve after assembly can lead to severe vibration and wear of the valve core, affecting its service life and reliability. Therefore, improvements are needed. Utility Model Content

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one objective of this invention is to provide an integrated flow path module that mounts a throttle valve component on a mounting module, such that the angle between the axis of the throttle valve component and the vertical direction is set between 0° and 30°. This allows the axis of the throttle valve component to extend approximately in the vertical direction, thereby reducing vibration and wear of the valve core, extending the service life of the throttle valve component, and improving its reliability.

[0004] This utility model also proposes an air conditioning system having the above-mentioned integrated flow path module.

[0005] This utility model also proposes an outdoor air conditioning unit having the above-mentioned integrated flow path module.

[0006] According to an embodiment of the first aspect of the utility model, the integrated flow path module includes a throttling valve assembly. The throttling valve assembly includes: a valve island, in which a refrigerant flow path, a first flow channel port, a second flow channel port, a third flow channel port, and at least one mounting port are formed. The first flow channel port, the second flow channel port, the third flow channel port, and at least one mounting port are all connected to the refrigerant flow path. The second flow channel port and the third flow channel port face the same side. The angle between the orientation of the first flow channel port and the orientation of the second flow channel port is ω1, 60°≤ω1≤180°, and / or the angle between the orientation of the mounting port and the orientation of the second flow channel port is ω2, 60°≤ω2≤180°; and at least one throttling valve component connected to the mounting port. The angle between the axis of the throttling valve component and the vertical direction is e, 0°≤e≤30°.

[0007] According to the integrated flow path module of this utility model embodiment, the integrated flow path module includes a throttling valve assembly, wherein the throttling valve assembly includes a valve island and a throttling valve component connected to the valve island. The valve island has a refrigerant flow path, a first flow port, a second flow port, a third flow port, and at least one mounting port for connecting the throttling valve component. The throttling valve component and other components connected to the valve island can be integrated on the valve island, making the flow path more concentrated, reducing the use of pipelines, thereby reducing the complexity of the pipeline and simplifying the structure. Furthermore, the angle between the axis of the throttling valve component and the vertical direction is set. Within the 0°–30° range, the axis of the throttle valve component can be extended approximately vertically. This allows the valve core to droop naturally under gravity, resulting in a tighter contact between the valve core and the valve seat. This reduces frictional wear between the valve core and seat caused by horizontal vibration. Furthermore, at least a portion of the refrigerant flow within the throttle valve component aligns with the direction of gravity, reducing the lateral impact force of the refrigerant flow on the valve core. This also reduces vibration wear caused by fluid pulsation, thus extending the service life and improving the reliability of the throttle valve component. Additionally, having the second and third flow channels face the same side facilitates connection to other components, such as plate heat exchangers.

[0056] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein 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 with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0057] The following is for reference. Figures 1-9 The integrated flow path module 1 according to an embodiment of the present utility model is described.

[0058] Reference Figures 1-3 The integrated flow path module 1 according to the first aspect of the present invention includes: a throttle valve assembly.

[0059] Reference Figures 5-8 The throttle valve assembly includes a valve island 14, within which a refrigerant flow path, a first flow port 1401, a second flow port 1402, a third flow port 1403, and at least one mounting port 1490 are formed. The first flow port 1401, the second flow port 1402, the third flow port 1403, and the at least one mounting port 1490 are all connected to the refrigerant flow path. This allows the throttle valve assembly to be realized.

[0060] The second flow channel 1402 and the third flow channel 1403 face the same side. This arrangement facilitates the connection of other components, such as plate heat exchangers, to the second flow channel 1402 and the third flow channel 1403.

[0061] Reference Figures 5-8 The throttle valve assembly includes at least one throttle valve component 120, which is connected to the mounting port 1490, thereby enabling flow path communication between the throttle valve component and the valve island 14. Furthermore, the refrigerant flow path, first flow port 1401, second flow port 1402, and third flow port 1403 provided on the valve island 14 can be connected to other components with refrigerant flow paths. This allows multiple components, including the throttle valve component 120, to be integrated onto the valve island 14, reducing piping connections between components, lowering piping complexity, and simplifying the structure.

[0062] A throttle valve assembly may include one or more throttle valve components 120. For example, a throttle valve assembly may include one throttle valve component 120, to which the valve island 14 has a mounting port 1490. Alternatively, a throttle valve assembly may include two throttle valve components 120. When a throttle valve assembly includes multiple throttle valve components 120, these components can be integrated onto the valve island 14, which has multiple mounting ports 1490. Each throttle valve component 120 can be connected to a corresponding mounting port 1490, facilitating the installation, inspection, and maintenance of the multiple throttle valve components 120.

[0063] Among them, reference Figure 3 The angle between the axis of the throttle valve component 120 and the vertical direction is e, where 0° ≤ e ≤ 30°. For example, the angle e between the axis of the throttle valve component 120 and the vertical direction can be 0°, 5°, 10°, 15°, 20°, 25°, 30°, etc. This allows the axis of the throttle valve component 120 to extend approximately in the vertical direction, and the valve core to hang naturally under gravity, resulting in a tighter contact between the valve core and the valve seat. This reduces frictional wear between the valve core and the valve seat caused by horizontal vibration. Furthermore, at least part of the refrigerant flow direction within the throttle valve component 120 is roughly consistent with the direction of gravity, reducing the lateral impact force of the refrigerant flow on the valve core. This also reduces vibration wear of the valve core caused by fluid pulsation, thereby reducing vibration wear of the valve core.

[0064] Optionally, refer to Figure 5 The orientation of the first flow channel 1401 (refer to) Figure 5 The direction indicated by the straight line f1 with arrows in the middle) and the orientation of the second flow channel opening 1402 (refer to...) Figure 5 The angle between the direction indicated by the straight line f2 with arrows is ω1, where 60°≤ω1≤180°. By setting the angle ω1 between the orientation of the first flow channel 1401 and the orientation of the second flow channel 1402 to a range of 60°~180°, it is convenient to connect the throttle valve component 120 or other components to the valve island 14.

[0065] Optionally, refer to Figure 5 Orientation of installation port 1490 (refer to) Figure 5 The direction indicated by the straight line g with arrow in the middle) and the orientation of the second flow channel opening 1402 (refer to...) Figure 5 The angle between the direction indicated by the straight line f2 with arrows is ω2, where 60°≤ω2≤180°. By setting the angle ω2 between the orientation of the mounting port 1490 and the orientation of the second flow channel port 1402 to a range of 60°~180°, it is convenient to connect the throttle valve component 120 to the valve island 14.

[0066] It should be explained that the orientation of the flow channel opening (including the orientation of the first flow channel opening 1401 and the orientation of the second flow channel opening 1402) refers to the direction perpendicular to the plane where the flow channel opening is located and towards the direction away from the valve island 14; the orientation of the mounting port 1490 refers to the direction perpendicular to the plane where the mounting port 1490 is located and towards the direction away from the valve island 14.

[0067] According to the integrated flow path module 1 of this utility model embodiment, the integrated flow path module 1 includes a throttling valve assembly, which includes a valve island 14 and a throttling valve component 120 connected to the valve island 14. The valve island 14 has a refrigerant flow path, a first flow port 1401, a second flow port 1402, a third flow port 1403, and at least one mounting port 1490 for connecting the throttling valve component 120. The throttling valve component 120 and other components connected to the valve island 14 can be integrated on the valve island 14, making the flow path more concentrated, reducing the use of pipelines, thereby reducing the complexity of the pipelines and simplifying the structure. Furthermore, the angle between the axis of the throttling valve component 120 and the vertical direction is set between 0° and 30°, which allows the axis of the throttling valve component 120 to extend approximately in the vertical direction, reducing the vibration and wear of the valve core, extending the service life of the throttling valve component 120, and improving the reliability of the throttling valve component 120. In addition, by making the second flow port 1402 and the third flow port 1403 face the same side, it is convenient for other components, such as plate heat exchangers, to be connected to the second flow port 1402 and the third flow port 1403. By setting the angle between the orientation of the first flow port 1401 and the orientation of the second flow port 1402 and / or the angle between the orientation of the mounting port 1490 and the orientation of the second flow port 1402 to a range of 60° to 180°, it is convenient to install the throttle valve component 120 on the valve island 14.

[0068] According to some embodiments of this utility model, refer to Figures 1-3 The integrated flow path module 1 includes a mounting module 11 and a throttle valve assembly, with the throttle valve assembly mounted on the mounting module 11. Mounting the throttle valve assembly on the mounting module 11 facilitates its installation and fixation. For example, the mounting module 11 can be a functional component in the air conditioning system 100, which may have a flow channel or cavity through which refrigerant flows; the mounting module 11 can also be a mounting bracket.

[0069] According to some embodiments of this utility model, refer to Figures 1-3The mounting module 11 has a mounting surface 1103, which can be a plane. The throttle valve assembly is mounted on the mounting surface 1103. The angle between the mounting surface 1103 and the vertical direction is less than or equal to the angle between the axis of the throttle valve component 120 and the vertical direction. For example, the angle between the mounting surface 1103 and the vertical direction can be 0°, and the angle between the axis of the throttle valve component 120 and the vertical direction can be greater than 0°. In this way, when the integrated flow path module 1 is installed into the whole machine, the mounting surface 1103 of the mounting module 11 can be set approximately in the vertical direction. The axis of the throttle valve component 120 can extend approximately in the up-down direction to reduce valve core vibration and wear, while also allowing a certain angle between the axis of the throttle valve component 120 and the mounting surface 1103 of the mounting module 11. This facilitates the installation and fixation of the throttle valve component 120 and makes the overall structure of the throttle valve component 120 and the mounting module 11 compact.

[0070] According to some embodiments of this utility model, refer to Figures 1-3 The angle between the axis of the throttle valve component 120 and the plane containing the mounting surface 1103 is b, where -30° ≤ b ≤ 30°. For example, the angle b between the axis of the throttle valve component 120 and the plane containing the mounting surface 1103 can be -30°, -20°, -10°, 0°, 10°, 15°, 20°, 30°, etc. By ensuring that the angle b between the axis of the throttle valve component 120 and the plane containing the mounting surface 1103 satisfies -30° ≤ b ≤ 30°, the vibration and wear of the valve core of the throttle valve component 120 can be reduced, the installation and fixation of the throttle valve component 120 can be facilitated, and the overall structure of the throttle valve component 120 and the mounting module 11 can be made more compact.

[0071] According to some embodiments of this utility model, refer to Figures 1-3 The throttle valve component 120 includes a coil portion and a valve core, and the projection of the coil portion onto the mounting surface 1103 at least partially covers the mounting surface 1103. By ensuring that the projection of the coil portion of the throttle valve component 120 onto the plane containing the mounting surface 1103 at least partially covers the mounting surface 1103, the overall structure of the integrated flow path module 1 can be made more compact.

[0072] According to some embodiments of this utility model, refer to Figures 1-3 The throttle valve component 120 includes a coil portion and a valve core. The coil portion is disposed above or diagonally above the valve island 14 and is connected to the valve island 14 via a connector. By disposing the coil portion of the throttle valve component 120 above or diagonally above the valve island 14, vibration wear of the valve core of the throttle valve component 120 can be reduced.

[0073] According to some embodiments of this utility model, refer to Figures 5-8 The orientation of the first flow channel 1401 (refer to) Figure 5The direction indicated by the straight line f1 with arrows in the middle) and the orientation of the second flow channel opening 1402 (refer to...) Figure 5 The angle between the direction indicated by the straight line f2 with arrows is ω1, where 90°≤ω1≤180°. By setting the angle ω1 between the orientation of the first flow channel 1401 and the orientation of the second flow channel 1402 to a range of 90°~180°, it is convenient to connect the throttle valve component 120 or other components to the valve island 14.

[0074] According to some embodiments of this utility model, refer to Figures 5-8 Orientation of installation port 1490 (refer to) Figure 5 The direction indicated by the straight line g with arrow in the middle) and the orientation of the second flow channel opening 1402 (refer to...) Figure 5 The angle between the direction indicated by the straight line f2 with arrows is ω2, where 90°≤ω2≤180°. By setting the angle ω2 between the orientation of the mounting port 1490 and the orientation of the second flow channel port 1402 to a range of 90°~180°, it is convenient to connect the throttle valve component 120 to the valve island 14.

[0075] According to some embodiments of this utility model, refer to Figures 5-8 The mounting port 1490 faces the same side as the first flow channel port 1401. This facilitates the connection of the throttle valve component 120 and other components to the valve island 14.

[0076] According to some embodiments of this utility model, refer to Figures 5-8 The mounting port 1490 faces the opposite side to the first flow channel port 1401. This facilitates the connection of the throttle valve component 120 and other components to the valve island 14.

[0077] According to some embodiments of this utility model, refer to Figures 1-3 The throttle valve assembly includes two throttle valve components 120. The valve 14 has two mounting ports 1490. The two throttle valve components 120 are a first throttle valve component 12 and a second throttle valve component 13, respectively. The two mounting ports 1490 are a first mounting port 1491 and a second mounting port 1492, respectively. The first throttle valve component 12 is connected to the first mounting port 1491, and the second throttle valve component 13 is connected to the second mounting port 1492. Both the first throttle valve component 12 and the second throttle valve component 13 are connected to the valve island 14. Integrating the two throttle valve components 120 onto the valve island 14 facilitates their installation and maintenance, resulting in a more compact overall structure for the integrated flow path module 1.

[0078] According to some embodiments of this utility model, refer to Figures 1-3 , Figure 6The angle between the axis L1 of the first throttle valve component 12 and the axis of the second throttle valve component 13 is θ, where 0°≤θ≤180°. For example, the value of θ can be 5°, 30°, 45°, 60°, 90°, 120°, 150°, 160°, 170°, etc. By ensuring that the angle θ between the axis L1 of the first throttle valve component 12 and the axis of the second throttle valve component 13 satisfies 0°≤θ≤180°, the axis L1 of the first throttle valve component 12 and the axis of the second throttle valve component 13 are not parallel, making the overall structure of the integrated flow path module 1 more compact.

[0079] According to some embodiments of this utility model, 5°≤θ≤90°. For example, the value of θ can be 6°, 10°, 20°, 30°, 40°, 45°, 50°, 60°, 70°, 80°, etc. By ensuring that the included angle θ between the axis L1 of the first throttle valve component 12 and the axis of the second throttle valve component 13 satisfies 5°≤θ, the axis L1 of the first throttle valve component 12 and the axis of the second throttle valve component 13 are not parallel, which facilitates the installation and fixation of the first throttle valve component 12 and the second throttle valve component 13. When the angle between the axis L1 of the first throttle valve component 12 and the axis of the second throttle valve component 13 is too large, the space occupied by the first throttle valve component 12 and the second throttle valve component 13 in the width direction of the mounting surface 1103 will be large, thereby increasing the space occupied by the integrated flow path module 1. By ensuring that the angle θ between the axis L1 of the first throttle valve component 12 and the axis of the second throttle valve component 13 satisfies θ≤90°, the overall structure of the integrated flow path module 1 is made more compact.

[0080] According to some embodiments of this utility model, refer to Figures 1-3 , Figure 6The integrated flow path module 1 includes a mounting module 11 and a throttle valve assembly, the throttle valve assembly being mounted on the mounting module 11. The mounting module 11 has a mounting surface 1103, on which the throttle valve assembly is mounted. The angle between the projections of the axis L1 of the first throttle valve component 12 and the axis of the second throttle valve component 13 onto the plane of the mounting surface 1103 is α, where 0°≤a≤60°. For example, the value of α can be 5°, 10°, 20°, 30°, 40°, 45°, 50°, 55°, etc. If the angle α between the projections of the axis L1 of the first throttle valve component 12 and the axis of the second throttle valve component 13 onto the plane of the mounting surface 1103 is too large, it will result in a larger space occupied by the first throttle valve component 12 and the second throttle valve component 13 in the width direction of the mounting surface 1103, thereby increasing the space occupied by the integrated flow path module 1. By ensuring that the included angle α between the projections of the axis L1 of the first throttle valve component 12 and the axis of the second throttle valve component 13 onto the plane of the mounting surface 1103 satisfies 0°≤a≤60°, the integrated flow path module 1 can be made smaller in the width direction, resulting in a more compact overall structure.

[0081] The value of a can be the same as the value of θ mentioned above.

[0082] According to some embodiments of this utility model, refer to Figures 5-8 The second flow channel 1402 and the third flow channel 1403 are located in the same plane. By placing the second flow channel 1402 and the third flow channel 1403 in the same plane, it is convenient to connect other components to the valve island 14, and it is also convenient to process the second flow channel 1402 and the third flow channel 1403 on the valve island 14.

[0083] According to some embodiments of this utility model, refer to Figures 1-3 The mounting surface 1103 is rectangular, and the first throttle valve component 12 and the second throttle valve component 13 are arranged along the width direction of the mounting surface 1103. By arranging the first throttle valve component 12 and the second throttle valve component 13 along the width direction of the mounting surface 1103, the overall structure of the integrated flow path module 1 can be made more compact, reducing the space occupied by the integrated flow path module 1.

[0084] According to some embodiments of this utility model, refer to Figures 1-3The angle between the axis L1 of the first throttle valve component 12 and the length direction of the mounting surface 1103 is α1, where 0° < α1 < 180°. For example, the axis L1 of the first throttle valve component 12 can be the axis of the valve core of the first throttle valve component 12. The axis of the first throttle valve component 12 is L1, and the value of α1 can be 5°, 10°, 30°, 45°, 60°, 75°, 90°, 120°, 135°, 160°, etc. By ensuring that the angle α1 between the axis L1 of the first throttle valve component 12 and the length direction of the mounting surface 1103 satisfies 0° < α1 < 180°, the overall structure of the integrated flow path module 1 can be made more compact, reducing the space occupied by the integrated flow path module 1.

[0085] According to some embodiments of this utility model, refer to Figures 1-3 5° < α1 < 60°. For example, the value of α1 can be 6°, 10°, 20°, 30°, 40°, 45°, 50°, 55°, etc. The axis L1 of the first throttle valve component 12 can be inclined to a certain extent relative to the length direction of the mounting surface 1103. This makes full use of the space on one side of the mounting surface 1103 and reduces interference between the first throttle valve component 12 and the second throttle valve component 13 during installation, making it easier to install the first throttle valve component 12 and the second throttle valve component 13 on the mounting surface 1103 and making the overall installation compact.

[0086] According to some embodiments of this utility model, refer to Figures 1-3 The angle between the axis of the second throttling valve component 13 and the length direction of the mounting surface 1103 is α2, where 0° < α2 < 180°. For example, the axis of the second throttling valve component 13 can be the axis of the valve core of the second throttling valve component 13, and the axis of the second throttling valve component 13 is L2. The value of α2 can be 5°, 10°, 30°, 45°, 60°, 75°, 90°, 120°, 135°, 160°, etc. By ensuring that the angle α2 between the axis of the second throttling valve component 13 and the length direction of the plate heat exchanger 11 satisfies 0° < α2 < 180°, the overall structure of the integrated flow path module 1 can be made more compact, reducing the space occupied by the integrated flow path module 1.

[0087] According to some embodiments of this utility model, refer to Figures 1-35° < α2 < 60°. For example, the value of α2 can be 6°, 10°, 20°, 30°, 40°, 45°, 50°, 55°, etc. The axis of the second throttle valve component 13 can be inclined to a certain extent relative to the length direction of the mounting surface 1103. This makes full use of the space on one side of the mounting surface 1103 and reduces interference between the first throttle valve component 12 and the second throttle valve component 13 during installation, making it easier to install the first throttle valve component 12 and the second throttle valve component 13 on the mounting surface 1103 and making the overall installation compact.

[0088] According to some embodiments of this utility model, refer to Figures 1-3 The absolute value of the difference between α1 and α2 is less than 60°. When the absolute value of the difference between α1 and α2 is too large, the angle between the axis L1 of the first throttle valve component 12 and the axis L2 of the second throttle valve component 13 is too large. This will cause the maximum length of the first throttle valve component 12 and the second throttle valve component 13 in the width direction of the mounting surface 1103 to be too large, increasing the space occupied by the integrated flow path module 1. By making the absolute value of the difference between α1 and α2 less than 60°, the total length of the integrated flow path module 1 in the width direction of the mounting surface 1103 can be appropriately reduced, making the overall structure of the integrated flow path module 1 more compact and avoiding the problem of the total length of the integrated flow path module 1 in the width direction being too large due to the large relative opening angle between the first throttle valve component 12 and the second throttle valve component 13, which would lead to installation difficulties.

[0089] According to some embodiments of this utility model, refer to Figures 1-3 The integrated flow path module 1 includes a mounting module 11 and a throttle valve assembly, the throttle valve assembly being mounted on the mounting module 11. The mounting module 11 is a plate heat exchanger, and may include multiple heat exchange plates 110 stacked together, a first plate 1101, and a second plate 1102. In the stacking direction of the multiple heat exchange plates 110, the first plate 1101 and the second plate 1102 are disposed on both sides of the stacked heat exchange plates 110, wherein the first plate 1101 includes a mounting surface 1103, the mounting surface 1103 being located on the side of the first plate 1101 facing away from the heat exchange plates 110. The mounting surface 1103 is provided with a first heat exchange interface 111, a second heat exchange interface 112, a third heat exchange interface 113 and a fourth heat exchange interface 114. The mounting module 11 forms a first heat exchange channel and a second heat exchange channel that exchange heat with each other. The first heat exchange channel connects the first heat exchange interface 111 and the second heat exchange interface 112, and the second heat exchange channel connects the third heat exchange interface 113 and the fourth heat exchange interface 114. The second channel port 1402 is connected to the second heat exchange interface 112, and the third channel port 1403 is connected to the third heat exchange interface 113.

[0090] One of the first heat exchange port 111 and the second heat exchange port 112 serves as the inlet of the first heat exchange channel and the other serves as the outlet of the first heat exchange channel. One of the third heat exchange port 113 and the fourth heat exchange port 114 serves as the inlet of the second heat exchange channel and the other serves as the outlet of the second heat exchange channel.

[0091] By installing both the first throttling valve component 12 and the second throttling valve component 13 on the plate heat exchanger, the plate heat exchanger, the first throttling valve component 12, and the second throttling valve component 13 are integrated together. This reduces the length of the connecting pipes between the first throttling valve component 12, the second throttling valve component 13 and the plate heat exchanger, which helps to reduce the space occupied by the connecting pipes, reduces the number of pipe welding processes and the risk of weld leakage, reduces the risk of pipe vibration stress fracture, and improves pipe reliability. Furthermore, it makes the structure of the integrated flow path module 1 more compact and reduces the space occupied by the integrated flow path module 1.

[0092] By forming a first heat exchange channel and a second heat exchange channel for mutual heat exchange within the plate heat exchanger, two refrigerants at different temperatures can flow through the plate heat exchanger simultaneously. These two refrigerants at different temperatures can exchange heat with each other, and the direction of refrigerant flow can be changed depending on whether the air conditioning system 100 is in heating mode or cooling mode.

[0093] For example, refer to Figure 9 , Figure 9 The dashed arrows indicate the direction of refrigerant flow when the air conditioning system 100 is in heating mode. After the refrigerant is discharged from the exhaust port 41 of the compressor 4, it flows through the indoor heat exchanger 2. The refrigerant flowing out of the indoor heat exchanger 2 enters the first heat exchange channel of the plate heat exchanger through the first heat exchange interface 111. After exchanging temperature with the refrigerant in the second heat exchange channel in the first heat exchange channel, it flows out of the plate heat exchanger through the second heat exchange interface 112. The refrigerant flowing out of the plate heat exchanger from the second heat exchange port 112 is divided into two paths. One path of refrigerant enters the second throttling valve component 13, and after being throttled by the second throttling valve component 13, it leaves the second throttling valve component 13. At this time, the temperature of the refrigerant decreases due to the throttling effect of the second throttling valve component 13. It then enters the second heat exchange channel of the plate heat exchanger through the third heat exchange port 113. The temperature of the refrigerant in the second heat exchange channel is lower than that of the refrigerant in the first heat exchange channel. The refrigerant in the first heat exchange channel raises the temperature of the refrigerant in the second heat exchange channel. Then, it flows out of the plate heat exchanger through the fourth heat exchange port 114 and then flows into the compressor 4. The other path of refrigerant enters the first throttling valve component 12, and after being throttled by the first throttling valve component 12, it flows out of the first throttling valve component 12, then flows through the outdoor heat exchanger 3 and then flows into the compressor 4 through the return port 42 of the compressor 4.

[0094] For example, when the air conditioning system 100 is in heating mode, by raising the temperature of the refrigerant in the first heat exchange channel to that in the second heat exchange channel, the temperature of the refrigerant entering the compressor 4 can be increased, which can prevent liquid slugging and ensure the efficient operation of the compressor 4. It can also play a certain role in replenishing gas and increasing enthalpy for the compressor 4.

[0095] For example, refer to Figure 9 , Figure 9 The solid arrows indicate the refrigerant flow direction when the air conditioning system 100 is in cooling mode. After being discharged from the compressor 4, the refrigerant flows through the outdoor heat exchanger 3. The refrigerant exiting the outdoor heat exchanger 3 enters the first throttling valve component 12, and after being throttled by the first throttling valve component 12, it exits. The refrigerant exiting the first throttling valve component 12 splits into two paths. One path enters the second throttling valve component 13, and after being throttled by the second throttling valve component 13, it exits. At this point, the refrigerant's temperature decreases due to the throttling effect of the second throttling valve component 13, and it enters the second heat exchange channel of the plate heat exchanger through the third heat exchange interface 113. The temperature of the refrigerant in the second heat exchange channel is lower than that in the first heat exchange channel. The refrigerant in the first heat exchange channel is cooled down, and then leaves the plate heat exchanger through the fourth heat exchange port 114 and finally enters the compressor 4; the other refrigerant flows into the first heat exchange channel of the plate heat exchanger through the second heat exchange port 112, where the refrigerant in the second heat exchange channel cools down the refrigerant in the first heat exchange channel, and then leaves the plate heat exchanger through the first heat exchange port 111 and enters the indoor heat exchanger 2. After flowing through the indoor heat exchanger 2, it enters the compressor 4 through the return port 42 of the compressor 4.

[0096] When the air conditioning system 100 is in cooling mode, the refrigerant in the first heat exchange channel is cooled by the refrigerant in the second heat exchange channel. This increases the subcooling of the refrigerant in the first heat exchange channel, lowers the temperature of the refrigerant in the first heat exchange channel, and ultimately makes the temperature of the refrigerant entering the indoor heat exchanger 2 even lower, thereby improving the heat exchange performance of the indoor heat exchanger 2 and enhancing the temperature regulation capability of the air conditioning system 100.

[0097] According to some embodiments of this utility model, refer to Figures 1-3The mounting module 11 has a mounting surface 1103, on which the throttle valve assembly is mounted. The mounting surface 1103 has four connection ports corresponding to the first heat exchange interface 111, the second heat exchange interface 112, the third heat exchange interface 113, and the fourth heat exchange interface 114, respectively. The mounting surface 1103 has a first end 117 and a second end 118 arranged opposite to each other. The first heat exchange interface 111 and the fourth heat exchange interface 114 are positioned near the first end 117 of the mounting surface 1103, while the second heat exchange interface 112 and the third heat exchange interface 113 are positioned near the second end 118 of the mounting surface 1103. Since the first heat exchange interface 111 and the fourth heat exchange interface 114 are connected to other components of the air conditioning system 100, and the second heat exchange interface 112 and the third heat exchange interface 113 are connected to the throttle valve assembly. By setting the first heat exchange interface 111 and the fourth heat exchange interface 114 close to the first end 117 of the mounting surface 1103, and setting the second heat exchange interface 112 and the third heat exchange interface 113 close to the second end 118 of the mounting surface 1103, the connection between the heat exchange interfaces on the mounting module 11 and other components can be made more convenient.

[0098] According to some embodiments of this utility model, refer to Figures 1-3 The mounting surface 1103 is rectangular. The first end 117 and the second end 118 of the mounting surface 1103 are located at opposite ends along its length. The line connecting the center of the first heat exchange interface 111 and the center of the second heat exchange interface 112 is the first connecting line 115. The line connecting the center of the third heat exchange interface 113 and the center of the fourth heat exchange interface 114 is the second connecting line 116. The first connecting line 115 and the second connecting line 116 are spaced apart along the width direction of the mounting surface 1103. By arranging the first connecting line 115 and the second connecting line 116 spaced apart along the width direction of the mounting surface 1103, other components can be easily connected and installed to the mounting module 11 through the first heat exchange interface 111, the second heat exchange interface 112, the third heat exchange interface 113, or the fourth heat exchange interface 114, and interference between multiple components connected to the mounting module 11 can be avoided.

[0099] According to some embodiments of this utility model, refer to Figures 1-3The line connecting the center of the first heat exchange port 111 and the center of the second heat exchange port 112 is the first connecting line 115, and the line connecting the center of the third heat exchange port 113 and the center of the fourth heat exchange port 114 is the second connecting line 116. The angle between the axis of the first throttle valve component 12 and the first connecting line 115 is β1, where 0° < β1 < 180°. For example, the value of β1 can be 5°, 10°, 30°, 45°, 60°, 75°, 90°, 120°, 135°, 160°, etc. By ensuring that the angle β1 between the axis of the first throttle valve component 12 and the first connecting line 115 satisfies 0° < β1 < 180°, the overall structure of the integrated flow path module 1 can be made more compact, reducing the space occupied by the integrated flow path module 1.

[0100] According to some embodiments of this utility model, refer to Figures 1-3 5° < β1 < 60°. For example, the value of β1 can be 6°, 10°, 20°, 30°, 40°, 45°, 50°, 55°, etc. By ensuring that the included angle β1 between the axis of the first throttle valve component 12 and the first connecting line 115 satisfies 5° < β1, the axis of the first throttle valve component 12 can be inclined relative to the first connecting line 115 to make fuller use of the space on the mounting surface 1103 and facilitate the installation and fixing of the first throttle valve component 12. By ensuring that the included angle β1 between the axis of the first throttle valve component 12 and the first connecting line 115 satisfies β1 < 60°, the total length of the integrated flow path module 1 in the width direction of the mounting surface 1103 can be appropriately reduced, avoiding the integrated flow path module 1 occupying too much space and being difficult to install due to the excessively large inclination angle of the axis of the first throttle valve component 12 relative to the first connecting line 115.

[0101] According to some embodiments of this utility model, refer to Figures 1-3 The line connecting the center of the first heat exchange interface 111 and the center of the second heat exchange interface 112 is the first connecting line 115, and the line connecting the center of the third heat exchange interface 113 and the center of the fourth heat exchange interface 114 is the second connecting line 116. The angle between the axis L2 of the second throttle valve component 13 and the second connecting line 116 is β2, where 0° < β2 < 180°. For example, the value of β2 can be 5°, 10°, 30°, 45°, 60°, 75°, 90°, 120°, 135°, 160°, etc. By ensuring that the angle β2 between the axis L2 of the second throttle valve component 13 and the second connecting line 116 satisfies 0° < β2 < 180°, the overall structure of the integrated flow path module 1 can be made more compact, reducing the space occupied by the integrated flow path module 1.

[0102] According to some embodiments of this utility model, refer to Figures 1-35° < β2 < 60°. For example, the value of β2 can be 6°, 10°, 20°, 30°, 40°, 45°, 50°, 55°, etc. By ensuring that the included angle β2 between the axis L2 of the second throttle valve component 13 and the second connecting line 116 satisfies 5° < β2, the axis L2 of the second throttle valve component 13 can be inclined relative to the second connecting line 116 to make fuller use of the space on the mounting surface 1103 and facilitate the installation and fixing of the second throttle valve component 13. By ensuring that the included angle β2 between the axis L2 of the second throttle valve component 13 and the second connecting line 116 satisfies β2 < 60°, the total length of the integrated flow path module 1 in the width direction of the mounting surface 1103 can be appropriately reduced, avoiding the integrated flow path module 1 occupying too much space and being difficult to install due to the excessively large inclination angle of the axis L2 of the second throttle valve component 13 relative to the second connecting line 116.

[0103] According to some embodiments of this utility model, refer to Figures 1-3 The absolute value of the difference between β1 and β2 is less than 60°. When the absolute value of the difference between β1 and β2 is too large, the angle between the axis L1 of the first throttle valve component 12 and the axis L2 of the second throttle valve component 13 is too large. This will cause the maximum length of the first throttle valve component 12 and the second throttle valve component 13 in the width direction of the mounting surface 1103 to be too large, increasing the space occupied by the integrated flow path module 1 and making the installation of the integrated flow path module 1 more difficult. By making the absolute value of the difference between β1 and β2 less than 60°, the total length of the integrated flow path module 1 in the width direction of the mounting surface 1103 can be appropriately reduced, making the overall structure of the integrated flow path module 1 more compact and avoiding the excessively large relative opening angle between the first throttle valve component 12 and the second throttle valve component 13, which would lead to an excessively large total length of the integrated flow path module 1 in the width direction of the mounting surface 1103 and make installation difficult.

[0104] According to some embodiments of this utility model, refer to Figures 1-3The mounting surface 1103 has a first end 117 and a second end 118 that are disposed opposite to each other. The first heat exchange interface 111 and the fourth heat exchange interface 114 are disposed near the first end 117 of the mounting surface 1103, and the second heat exchange interface 112 and the third heat exchange interface 113 are disposed near the second end 118 of the mounting surface 1103. The throttle valve assembly is connected to the first heat exchange interface 111 and the fourth heat exchange interface 114 and is disposed near the second end 118. The throttle valve assembly is spaced apart from both the first heat exchange interface 111 and the fourth heat exchange interface 114. By connecting the throttle valve assembly to the first heat exchange port 111 and the fourth heat exchange port 114 and positioning it close to the second end 118, the space on the mounting surface 1103 located on the side of the first heat exchange port 111 and the fourth heat exchange port 114 near the second end 118 can be fully utilized. At the same time, the throttle valve assembly is spaced apart from both the first heat exchange port 111 and the fourth heat exchange port 114. This allows for the provision of installation space for connecting other pipes or components to the first heat exchange port 111 and the fourth heat exchange port 114, reducing the risk of installation interference and the difficulty of installation when connecting other pipes or components to the first heat exchange port 111 and the fourth heat exchange port 114.

[0105] According to some embodiments of this utility model, refer to Figures 1-4 The integrated flow path module 1 includes a first filter element 16, which is connected to the first heat exchange interface 111. By including the first filter element 16 in the integrated flow path module 1 and connecting it to the first heat exchange interface 111, the first filter element 16 can filter out impurities and contaminants in the refrigerant, reducing the risk of air conditioning system 100 failure due to pipe blockage.

[0106] According to some embodiments of this utility model, refer to Figures 1-4 The angle between the axis L3 of the first filter component 16 and the plane containing the mounting surface 1103 is i, where 80°≤i≤100°. For example, i can be 80°, 85°, 90°, 95°, 100°, etc. By setting the angle i between the axis L3 of the first filter component 16 and the plane containing the mounting surface 1103 to 80°~100°, the first filter component 16 can be installed and fixed approximately along the angle perpendicular to the mounting surface 1103. This makes full use of the space on the mounting surface 1103 and reduces the risk of interference between the first filter component 16 and the throttle valve assembly installed on the mounting surface 1103 during installation, thus facilitating the installation and fixing of the first filter component 16.

[0107] According to some embodiments of this utility model, refer to Figures 1-4One end of the first filter element 16 is connected to the first heat exchange interface 111, and the other end of the first filter element 16 is connected to the first connecting pipe 18, with the interior of the first filter element 16 communicating with the first connecting pipe 18. Connecting the other end of the first filter element 16 to the first connecting pipe 18 facilitates connection between the first filter element 16 and other components of the air conditioning system 100. At least a portion of the first connecting pipe 18 runs from the side of the throttle valve assembly away from the mounting surface 1103. By ensuring that at least a portion of the first connecting pipe 18 runs from the side of the throttle valve assembly away from the mounting surface 1103, the space on the side of the throttle valve assembly away from the mounting surface 1103 is utilized, facilitating the routing of the first connecting pipe 18 and reducing installation interference between the throttle valve assembly and the first connecting pipe 18, resulting in a compact overall structure of the integrated flow path module 1.

[0108] According to some embodiments of this utility model, refer to Figures 1-4 The fourth heat exchange interface 114 is connected to a second connecting pipe 19. Connecting the fourth heat exchange interface 114 to the mounting module 11 via the second connecting pipe 19 facilitates connection between the fourth heat exchange interface 114 and other components of the air conditioning system 100. The second connecting pipe 19 includes a first pipe section 191, which is directly connected to the fourth heat exchange interface. The angle between the axis L4 of the first pipe section 191 and the plane containing the mounting surface 1103 is j, where 80°≤j≤100°. For example, j can be 80°, 85°, 90°, 95°, 100°, etc. By setting the angle j between the axis L4 of the first pipe section 191 and the plane where the mounting surface 1103 is located to 80° to 100°, the first pipe section 191 can be installed and fixed approximately along the angle perpendicular to the mounting surface 1103. This makes full use of the space on the mounting surface 1103 and reduces the risk of interference between the second connecting pipe 19 and the throttle valve assembly installed on the mounting surface 1103 during the installation process, thus facilitating the installation and fixing of the second connecting pipe 19.

[0109] According to some embodiments of this utility model, refer to Figures 1-4The second connecting pipe 19 includes a second pipe segment 192, which is connected to the end of the first pipe segment 191 away from the fourth heat exchange interface 114. At least a portion of the second pipe segment 192 runs from the side of the throttle valve assembly away from the mounting surface 1103. The inclusion of the second pipe segment 192 in the second connecting pipe 19, with the second pipe segment 192 connected to the end of the first pipe segment 191 away from the fourth heat exchange interface 114, facilitates connection of the second connecting pipe 19 to other components of the air conditioning system 100. Furthermore, the fact that at least a portion of the second pipe segment 192 runs from the side of the throttle valve assembly away from the mounting surface 1103 allows for easier routing of the second connecting pipe 19 by utilizing the space on the side of the throttle valve assembly away from the mounting surface 1103, reducing installation interference between the throttle valve assembly and the second connecting pipe 19, and resulting in a compact overall structure for the integrated flow path module 1.

[0110] According to some embodiments of this utility model, refer to Figures 1-4 The throttle valve assembly includes a second filter element 17, which is located on the side of the first throttle valve assembly 12 opposite to the first end 117. By integrating the second filter element 17 into the throttle valve assembly and onto the mounting module 11, the number of connecting pipes between some components in the air conditioning system 100 can be reduced, the risk of leakage due to welding defects can be reduced, and the structure can be made more compact, reducing the space occupied. By placing the second filter element 17 on the side of the first throttle valve assembly 12 opposite to the first end 117, the space on the side of the first throttle valve assembly 12 opposite to the first end 117 can be utilized, and installation space can be provided for connecting other components at the first heat exchange interface 111, reducing the risk of installation interference.

[0111] The second filter element 17 can filter out impurities and contaminants in the refrigerant, reducing the risk of air conditioning system 100 failure due to pipe blockage. For example, when the air conditioning system 100 is in cooling mode, the second filter element 17 can reduce impurities in the refrigerant flowing from the outdoor heat exchanger 3 and into the second throttle valve element 13, reducing the risk of air conditioning system 100 failure due to blockage of the second throttle valve element 13. For example, when the air conditioning system 100 is in heating mode, the second filter element 17 can reduce impurities in the refrigerant flowing from the second throttle valve element 13 and into the outdoor heat exchanger 3, reducing the risk of air conditioning system 100 failure due to pipe blockage.

[0112] According to some embodiments of this utility model, refer to Figures 1-4The angle between the axis of the second filter component 17 and the axis of the first throttle valve component 12 is k, where 0° ≤ k ≤ 10°. For example, the value of k can be 0°, 2°, 4°, 6°, 8°, 10°, etc. By setting the angle k between the axis of the second filter component 17 and the axis of the first throttle valve component 12 to 0° to 10°, the connection between the second filter component 17 and the first throttle valve component 12 is facilitated, and the overall structure of the throttle valve assembly is also made more compact.

[0113] According to some embodiments of this utility model, refer to Figures 1-4 The axis of the second filter component 17 is parallel to and spaced apart from the axis of the first throttle valve component 12. By making the axes of the two filter components parallel to and spaced apart from the axis of the first throttle valve component 12, the overall structure of the throttle valve assembly can be made compact.

[0114] According to some embodiments of this utility model, refer to Figure 1 , Figure 2 , Figures 5-8 The throttle valve assembly also includes a temperature sensor 15, which is mounted on the valve island 14 and is used to detect the refrigerant temperature within the valve island 14. The temperature sensor 15 can be an embedded temperature-sensing sleeve. By installing the temperature sensor 15 on the valve island 14, the refrigerant temperature can be detected, facilitating the control of the air conditioning system 100. For example, the opening degree of the first throttle valve component 12 or the second throttle valve component 13 can be adjusted based on the refrigerant temperature detected by the temperature sensor 15.

[0115] For example, the temperature sensor 15 can be located near the connection point between the valve island 14 and the third heat exchange interface 113, so that the temperature sensor 15 can detect the temperature of the refrigerant entering the installation module 11 from the valve island 14.

[0116] According to some embodiments of this utility model, refer to Figure 1 , Figure 2 , Figures 5-8 Valve island 14 has a first flow channel 1402, a second flow channel 1402, and a third flow channel 1403. The second flow channel 1402 is connected to and communicates with the second heat exchange interface 112, and the third flow channel 1403 is connected to and communicates with the third heat exchange interface 113. Valve island 14 has a first valve chamber 147 and a second valve chamber 148. The first valve chamber 147 is correspondingly connected to and communicates with the first mounting port 1491, and the first throttling valve component 12 is connected to and communicates with the first valve chamber 147 through the first mounting port 1490. The second valve chamber 148 is correspondingly connected to and communicates with the second mounting port 1492, and the second throttling valve component 13 is connected to and communicates with the second valve chamber 148 through the second mounting port 1492.

[0117] The refrigerant flow path within the valve island 14 includes a first flow path 141, a second flow path 142, and a third flow path 143. The two ends of the first flow path 141 are connected to the first flow channel 1401 and the first valve chamber 147, respectively. The two ends of the second flow path 142 are connected to the second flow channel 1402 and the first valve chamber 147, respectively. The two ends of the third flow path 143 are connected to the first valve chamber 147 and the second valve chamber 148, respectively. The second valve chamber 148 is connected to the third flow channel 1403.

[0118] Valve island 14 has a first valve chamber 147 and a second valve chamber 148. A first throttling valve component 12 is configured to be connected to and communicate with the first valve chamber 147 so that refrigerant flowing through the first valve chamber 147 can flow through the first throttling valve component 12. A second throttling valve component 13 is configured to be connected to and communicate with the second valve chamber 148 so that refrigerant flowing through the second valve chamber 148 can flow through the second throttling valve component 13.

[0119] Valve island 14 defines a first flow path 141, a second flow path 142, and a third flow path 143 for the flow of refrigerant. The two ends of the first flow path 141 are connected to a first flow port 1401 and a first valve chamber 147, respectively, allowing the refrigerant to flow sequentially through the first flow port 1401, the first flow path 141, and the first valve chamber 147. The two ends of the second flow path 142 are connected to a second flow port 1402 and the first valve chamber 147, respectively, allowing the refrigerant to flow sequentially through the first valve chamber 147, the second flow path 142, the second flow port 1402, and the mounting module 11. The two ends of the third flow path 143 are connected to the first valve chamber 147 and the second valve chamber 148, respectively, allowing the refrigerant to flow sequentially through the first valve chamber 147, the third flow path 143, and the second valve chamber 148. The second valve chamber 148 is connected to the third flow port 1403, allowing the refrigerant to flow sequentially through the second valve chamber 148, the third flow port 1403, and the mounting module 11. The second valve chamber 148 and the third flow port 1403 can be directly or indirectly connected.

[0120] Therefore, the refrigerant can flow sequentially through the first flow port 1401, the first flow path 141, the first valve chamber 147, the second flow path 142, the second flow port 1402, and the installation module 11, or it can flow sequentially through the first flow port 1401, the first flow path 141, the first valve chamber 147, the third flow path 143, the second valve chamber 148, the third flow port 1403, and the installation module 11, thereby achieving communication between the first throttle valve component 12 and the second throttle valve component 13 and the installation module 11.

[0121] The first flow port 1401, the second flow port 1402, and the third flow port 1403 can all serve as inlets or outlets. For example, when the first flow port 1401 is used as an inlet, refrigerant can be introduced into the first flow path 141 through the first flow port 1401. When the first flow port 1401 is used as an outlet, the refrigerant flowing in the first flow path 141 can be discharged out of the expansion valve assembly through the first flow port 1401. Similarly, when the second flow port 1402 is used as an inlet, refrigerant can be introduced into the second flow path 142 through the second flow port 1402. When the second flow port 1402 is used as an outlet, the refrigerant flowing in the second flow path 142 can be discharged out of the expansion valve assembly, such as the mounting module 11. For example, when the third flow port 1403 is used as an inlet, refrigerant can be input into the second valve chamber 148 through the third flow port 1403. When the third flow port 1403 is used as an outlet, the refrigerant flowing in the second valve chamber 148 can be discharged to the outside of the throttle valve assembly, such as the mounting module 11, through the third flow port 1403.

[0122] Both the first throttle valve component 12 and the second throttle valve component 13 are used to control the flow rate and pressure of the refrigerant flowing through them, so as to achieve precise refrigerant flow regulation. For example, both the first throttle valve component 12 and the second throttle valve component 13 can throttle and reduce the pressure of the refrigerant flowing through them, thereby lowering the temperature and humidity of the refrigerant. Each of the first throttle valve component 12 and the second throttle valve component 13 can be an electronic expansion valve.

[0123] The first throttle valve component 12 and the second throttle valve component 13 are installed on the valve island 14 to achieve integration of the valve island 14, the first throttle valve component 12 and the second throttle valve component 13, reduce the space occupied by the valve island 14, the first throttle valve component 12 and the second throttle valve component 13, improve the structural compactness of the throttle valve assembly, and realize the miniaturization of the throttle valve assembly and the mounting module 11 as a whole.

[0124] The first throttling valve component 12 can throttle and reduce the pressure of the refrigerant flowing through it, and the second throttling valve component 13 can also throttle and reduce the pressure of the refrigerant flowing through it. By adjusting the opening degree of the first throttling valve component 12 and the second throttling valve component 13, the degree of throttling and pressure reduction of the refrigerant can be adjusted, so as to achieve the regulation of the pressure and temperature of the refrigerant in the valve island 14.

[0125] The throttling valve assembly defines multiple flow paths for refrigerant, both ends of which are connected to the outside of the throttling valve assembly. In each flow path, the refrigerant flows through at least one of the first throttling valve component 12 and the second throttling valve component 13. By adjusting the first flow port 1401, the second flow port 1402, and the third flow port 1403 as either inlets or outlets, the flow path of the refrigerant within the throttling valve assembly can be adjusted. The flow paths of the throttling valve assembly are diverse and flexibly adjustable. Combined with the adjustment of the opening degree of the first throttling valve component 12 and the second throttling valve component 13, the throttling function of the throttling valve assembly becomes more diverse.

[0126] For example, in some specific embodiments, the first flow port 1401 is used as the inlet, and the second flow port 1402 and the third flow port 1403 are both used as outlets. The refrigerant then flows along two flow paths within the throttling valve assembly. Specifically, the refrigerant entering the throttling valve assembly from the first flow port 1401 first flows within the first flow path 141 and passes through the first throttling valve component 12 in the first valve chamber 147. Adjusting the opening of the first throttling valve component 12 allows for the first throttling of the refrigerant. The refrigerant flowing out of the first flow path 141 splits into two paths: one flows into the second flow path 142 to exit the throttling valve assembly from the second flow port 1402 and enter the installation module 11; the other flows sequentially through the third flow path 143 and the second throttling valve component 13 in the second valve chamber 148, then exits the throttling valve assembly from the third flow port 1403 and enters the installation module 11. Adjusting the opening of the second throttling valve component 13 allows for a second throttling of the refrigerant.

[0127] For example, in some specific embodiments, the second flow port 1402 is used as an inlet, and the first flow port 1401 and the third flow port 1403 are both used as outlets. The refrigerant then flows along two flow paths within the throttling valve assembly. Specifically, the refrigerant input into the throttling valve assembly from the mounting module 11 via the second flow port 1402 flows through the second flow path 142. The refrigerant flowing out of the second flow path 142 is divided into two paths: one path flows sequentially through the first throttling valve component 12 of the first valve chamber 147, the first flow path 141, and the first flow port 1401 to exit the throttling valve assembly; the other path flows sequentially through the third flow path 143, the second throttling valve component 13 of the second valve chamber 148, and the third flow port 1403 to exit the throttling valve assembly and enter the mounting module 11.

[0128] In this application, the first throttle valve component 12 and the second throttle valve component 13 are installed through the valve island 14, integrating the first throttle valve component 12 and the second throttle valve component 13 into one unit, making the structure of the throttle valve assembly more compact. The second flow port 1402 and the third flow port 1403 of the throttle valve assembly are both connected and communicated with the mounting module 11, enabling the throttle valve assembly and the mounting module 11 to be integrated into one unit. This eliminates the need for multiple connecting pipes used to connect the mounting module 11 and the throttle valve in related technologies, making the overall structure of the throttle valve assembly and the mounting module 11 more streamlined, the pipeline length shorter, the overall volume of the throttle valve assembly and the mounting module 11 smaller, occupying less space, requiring less installation space, and eliminating the need to connect the mounting module 11 and multiple throttle valves sequentially, thus facilitating operation.

[0129] According to some embodiments of the present invention, the throttle valve assembly has a first conducting state and a second conducting state. When the throttle valve assembly is in the first conducting state, the first flow port 1401 is the refrigerant inlet, and the second flow port 1402 and the third flow port 1403 are both refrigerant outlets. When the throttle valve assembly is in the second conducting state, the second flow port 1402 is the refrigerant inlet, and the first flow port 1401 and the third flow port 1403 are both refrigerant outlets.

[0130] For example, when the throttle valve assembly is in the first conducting state, the first flow port 1401 is the refrigerant inlet, and the second flow port 1402 and the third flow port 1403 are both refrigerant outlets, connecting the two outlets of the throttle valve assembly to the mounting module 11. When the throttle valve assembly is in the second conducting state, the second flow port 1402 is the refrigerant inlet, and the first flow port 1401 and the third flow port 1403 are both refrigerant outlets, connecting one inlet and one outlet of the throttle valve assembly to the heat exchanger.

[0131] By switching between the first and second conduction states, the first flow port 1401, the second flow port 1402, and the third flow port 1403 can be adjusted to function as either an inlet or an outlet, thereby changing the connection state between the throttle valve assembly and the installation module 11 and adjusting the flow path of the refrigerant between them. This makes the flow path between the throttle valve assembly and the installation module 11 diverse and flexibly adjustable, which helps to meet the connection requirements between the installation module 11 and the throttle valve assembly in different operating modes and improves the working effect of the installation module 11 in different operating modes.

[0132] For example, in some embodiments, the mounting module 11 keeps the throttling valve assembly in a first conducting state in cooling mode. In cooling mode, the refrigerant flowing into the first heat exchange channel of the mounting module 11 from the second flow channel port 1402 has a lower temperature after being throttled by the first throttling valve component 12, and the refrigerant flowing into the second heat exchange channel of the mounting module 11 from the third flow channel port 1403 has an even lower temperature after being throttled by the first throttling valve component 12 and the second throttling valve component 13. After the lower-temperature refrigerant in the first heat exchange channel exchanges heat with the even lower-temperature refrigerant in the second heat exchange channel, the temperature of the refrigerant flowing out of the mounting module 11 from the first heat exchange channel is lower, resulting in better heat exchange effect and higher cooling efficiency of the mounting module 11.

[0133] In heating mode, the mounting module 11 keeps the throttle valve assembly in a second conducting state. In heating mode, the refrigerant in the first heat exchange channel is not throttled by the first throttle valve assembly 12 or the second throttle valve assembly 13. The refrigerant flowing into the second heat exchange channel from the third channel opening 1403 is throttled by the second throttle valve assembly 13 and has a lower temperature. After heat exchange between the higher-temperature refrigerant in the first heat exchange channel and the lower-temperature refrigerant in the second heat exchange channel, the temperature of the refrigerant flowing out of the mounting module 11 from the second heat exchange channel is higher. In the air conditioning system 100, including the throttle valve assembly and the mounting module 11, the temperature and pressure of the refrigerant flowing into the compressor 4 from the mounting module 11 are higher, which helps to increase the suction volume of the compressor 4.

[0134] According to some embodiments of this utility model, refer to Figures 5-8 The valve island 14 also defines a fourth flow path 144, the two ends of which are connected to the second valve chamber 148 and the third flow channel opening 1403, respectively. That is, the second valve chamber 148 is indirectly connected to the third flow channel opening 1403 through the fourth flow path 144. By setting the fourth flow path 144 in the valve island 14, the connection between the second valve chamber 148 and the third flow channel opening 1403 is easily realized.

[0135] For example, in some specific embodiments, the first flow path 141 includes a first straight portion 1411 that communicates with the first valve chamber 147 and forms a straight segment; the second flow path 142 includes a second straight portion 1421 that communicates with the second flow port 1402 and forms a straight segment; the third flow path 143 includes a third straight portion 1431 that communicates with the second valve chamber 148 and forms a straight segment; and the fourth flow path 144 includes a fourth straight portion 1441 that communicates with the third flow port 1403 and forms a straight segment. The second straight portion 1421 and the fourth straight portion 1441 are parallel, which can reduce the distance between the second flow port 1402 and the third flow port 1403, and can make the through direction of the openings of the heat exchanger for communicating with the second flow port 1402 and the third flow port 1403 parallel to the second straight portion 1421 and the fourth straight portion 1441, so that the second flow port 1402 and the third flow port 1403 can be easily connected to the heat exchanger.

[0136] According to some embodiments of this utility model, refer to Figures 5-8 The valve island 14 also defines a fifth flow path 145. The second flow path 142 and the third flow path 143 are both connected to one end of the fifth flow path 145, and the other end of the fifth flow path 145 is connected to the first valve cavity 147. That is, the first valve cavity 147 is connected to the fifth flow path 145 to simultaneously connect to the second flow path 142 and the third flow path 143. Through the fifth flow path 145, one end of the first valve cavity 147 can be divided into two paths to simultaneously connect to the second flow path 142 and the third flow path 143, eliminating the need to add an opening at one end of the first valve cavity 147 to separately connect to the second flow path 142 and the third flow path 143. This simplifies the structure of the valve island 14 and improves its structural strength.

[0137] In some embodiments, the third flow path 143 is bent and extended. By adjusting the included angle between the bent and extended segments of the third flow path 143, the two ends of the third flow path 143 can be made perpendicular to the adjacent flow path, which helps to reduce the flow resistance at the two ends of the third flow path 143 and increase the flow rate of the refrigerant.

[0138] For example, in some embodiments, reference Figures 5-8 The third flow path 143 includes a first segment and a second segment connected together (i.e., the third straight section 1431), and the extension directions of the first segment and the second segment are at an angle. By adjusting the angle between the extension directions of the first segment and the second segment, the extension direction of the first segment can be made perpendicular to the extension directions of both the fifth flow path 145 and part of the second flow path 142, and the extension direction of the second segment can be perpendicular to the axial direction of the second throttle valve component 13, which helps to reduce the flow resistance at both ends of the third flow path 143.

[0139] According to some embodiments of this utility model, refer to Figure 1 and Figure 8The valve island 14 also includes a mounting base 146, which defines a receiving cavity. A second filter element 17 is disposed within the receiving cavity and is connected to and communicates with the first flow channel 1401. By including the mounting base 146 in the valve island 14 and having a receiving cavity in the mounting base 146, the installation and fixation of the second filter element 17 are facilitated, as is the connection between the second filter element 17 and the first flow channel 1401 of the valve island 14. This makes the overall structure of the throttle valve assembly more compact.

[0140] Reference Figure 10 An air conditioning system 100 according to a second aspect embodiment of the present invention includes an integrated flow path module 1 according to the first aspect embodiment of the present invention.

[0141] According to the embodiment of the present invention, the air conditioning system 100, by setting the above-mentioned integrated flow path module 1, makes the flow path more concentrated, reduces the use of pipes, thereby reducing the complexity of the pipes and simplifying the structure; and the integrated flow path module 1 installs the throttle valve component 120 on the mounting module 11 and sets the angle between the axis of the throttle valve component 120 and the vertical direction to 0° to 30°, so that the axis of the throttle valve component 120 extends approximately in the vertical direction, thereby reducing the vibration and wear of the valve core, extending the service life of the throttle valve component 120, and improving the reliability of the throttle valve component 120.

[0142] In some embodiments, refer to Figure 10 The air conditioning system 100 includes: an indoor heat exchanger 2, an outdoor heat exchanger 3, a compressor 4, and an integrated flow path module 1. Both the indoor heat exchanger 2 and the outdoor heat exchanger 3 are connected to the compressor 4. The integrated flow path module 1 includes a throttling valve assembly and an installation module 11. The installation module 11 is a plate heat exchanger. The throttling valve assembly includes a valve island 14, a first throttling valve component 12, and a second throttling valve component 13. The first heat exchange interface 111 of the installation module 11 is connected to the indoor heat exchanger 2, and the fourth heat exchange interface 114 is connected to the compressor 4.

[0143] According to some embodiments of this utility model, refer to Figure 10 The air conditioning system 100 also includes a four-way valve 5, which has a first valve port 51, a second valve port 52, a third valve port 53, and a fourth valve port 54. The first valve port 51 is connected to the exhaust port 41 of the compressor 4, the second valve port 52 is connected to the indoor heat exchanger 2, the third valve port 53 is connected to both the return port 42 of the compressor 4 and the fourth heat exchange interface 114, and the fourth valve port 54 is connected to the outdoor heat exchanger 3. By including the four-way valve 5 in the air conditioning system 100, the air conditioning system 100 can be easily switched between cooling and heating modes, and the connection between the different valve ports can be adjusted according to the cooling or heating needs.

[0144] For example, refer to Figure 10 , Figure 10 The solid arrow in the figure indicates the direction of refrigerant flow when the air conditioning system 100 is in cooling mode. At this time, the first valve port 51 of the four-way valve 5 can be connected to the fourth valve port 54, the second valve port 52 and the third valve port 53 can be connected, and the first valve port 51 and the second valve port 52 cannot be connected to each other. The refrigerant discharged from the exhaust port 41 of the compressor 4 enters the four-way valve 5 through the first valve port 51, leaves the four-way valve 5 through the fourth valve port 54, and then flows into the outdoor heat exchanger 3 for heat exchange. The refrigerant flowing through the outdoor heat exchanger 3 flows into the first throttling device for throttling. After being throttled by the first throttling device, the refrigerant is divided into two paths. One path of refrigerant flows through the second throttling device and the second heat exchange channel of the installation module 11, and then flows into the compressor 4 through the return port 42 of the compressor 4. The other path of refrigerant flows through the first heat exchange channel of the installation module 11 and the indoor heat exchanger 2, enters the four-way valve 5 through the second valve port 52, leaves the four-way valve 5 through the third valve port 53, and then flows into the compressor 4 through the return port 42 of the compressor 4.

[0145] For example, refer to Figure 10 , Figure 10 The dashed arrows indicate the refrigerant flow direction when the air conditioning system 100 is in heating mode. At this time, the first valve port 51 of the four-way valve 5 is connected to the second valve port 52, and the third valve port 53 is connected to the fourth valve port 54. The first valve port 51 and the third valve port 53 are not connected to each other. The refrigerant discharged from the exhaust port 41 of the compressor 4 enters the four-way valve 5 through the first valve port 51, then leaves the four-way valve 5 through the second valve port 52, flows into the indoor heat exchanger 2 for heat exchange, and then flows into the first heat exchange channel of the installation module 11. The refrigerant flowing out of the first heat exchange channel is divided into two paths. One path of refrigerant flows through the second expansion valve and the second heat exchange channel of the installation module 11, and then flows into the compressor 4 through the return port 42 of the compressor 4. The other path of refrigerant flows through the first expansion valve and the outdoor heat exchanger 3, then enters the four-way valve 5 through the fourth valve port 54, then leaves the four-way valve 5 through the third valve port 53, and flows into the compressor 4 through the return port 42 of the compressor 4.

[0146] An outdoor air conditioning unit according to a third aspect embodiment of the utility model includes: a housing, a compressor, a fan, and an integrated flow path module according to the first aspect embodiment of the utility model described above. The housing includes an outer shell and a partition plate installed inside the outer shell. The outer shell forms an installation space, and the partition plate divides the installation space into a compressor cavity and a fan cavity.
