Description

Technical Field

[0001] This utility model relates to the field of air handling equipment technology, and in particular to a flow path switching module, an air conditioning system and an air conditioner. Background Technology

[0002] In related technologies, flow path switching modules are used for flow path switching. Flow path switching modules need to be wrapped with damping adhesive to reduce vibration, and when valve cores with poor temperature resistance are welded to pipelines, they need to be wrapped with wet cloths to cool them down. Existing flow path switching modules are not convenient to wrap with damping adhesive or wet cloths, and are prone to problems such as excessive noise due to improper wrapping of damping adhesive and failure of flow path switching module function due to overheating during welding. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a flow path switching module, which facilitates the application of shock-absorbing adhesive and a damp cloth.

[0004] This utility model also proposes an air conditioning system, which includes the above-mentioned flow path switching module.

[0005] This utility model also proposes an air conditioner, which includes the above-mentioned air conditioning system.

[0006] The flow path switching module according to an embodiment of this utility model includes: a first control valve, a second control valve, a third control valve, and a fourth control valve. The axes of the first control valve, the second control valve, the third control valve, and the fourth control valve are parallel to each other and do not coincide. The first control valve, the second control valve, the third control valve, and the fourth control valve are connected end to end in a ring. There is a first connection port between the first control valve and the second control valve, a second connection port between the second control valve and the third control valve, a third connection port between the third control valve and the fourth control valve, and a fourth connection port between the first control valve and the fourth control valve. The arrangement direction of the first control valve and the second control valve is the same as that of the third control valve and the fourth control valve. Along the arrangement direction of the first control valve and the second control valve, the maximum distance between the first control valve and the second control valve is A1, the maximum distance between the third control valve and the fourth control valve is A2, and the maximum size of the flow path switching module is A, satisfying: A > A1, and / or, A > A2.

[0007] According to the flow path switching module of this utility model embodiment, by making the maximum distance between the first and second control valves along the arrangement direction of the first and second control valves A1, the maximum distance between the third and fourth control valves A2, and the maximum size of the flow path switching module A, and satisfying: A > A1, and / or, A > A2, it is possible to make the line connecting the axes of the first, second, third, and fourth control valves non-rectangular on the projection plane perpendicular to the axis of the first control valve. When the first, second, third, and fourth control valves are wrapped with damping adhesive or wet cloth, the contact area between the first, second, third, and fourth control valves and the damping adhesive or wet cloth can be increased. This eliminates the need to wrap damping adhesive and wet cloth between two of the first, second, third, and fourth control valves, making it easier to wrap the damping adhesive and wet cloth, shortening the working time, and reducing the problem of excessive noise due to improper wrapping of damping adhesive, as well as the problem of the flow path switching module malfunction due to overheating during welding.

[0008] According to some embodiments of the present invention, on a projection plane perpendicular to the axis of the first control valve, the line connecting the axis of the first control valve and the axis of the second control valve is L1, and the line connecting the axis of the third control valve and the axis of the fourth control valve is L2, wherein L1 is parallel to L2.

[0013] According to some embodiments of the present invention, on a projection plane perpendicular to the axis of the first control valve, the line connecting the axis of the first control valve and the axis of the second control valve is L1, and the line connecting the axis of the third control valve and the axis of the fourth control valve is L2, wherein L1 and L2 are located on the same straight line.

[0014] In some embodiments of this utility model, the first control valve and the second control valve are located between the third control valve and the fourth control valve.

[0017] According to some embodiments of the present invention, the first control valve, the second control valve, the third control valve, and the fourth control valve are one-way valves.

[0018] The air conditioning system according to an embodiment of the present invention includes the flow path switching module described above.

[0019] According to the air conditioning system of this utility model embodiment, by setting the above-mentioned flow path switching module, not only can the flow path switching be realized, but also the maximum distance between the first control valve and the second control valve along the arrangement direction of the first control valve and the second control valve is A1, the maximum distance between the third control valve and the fourth control valve is A2, the maximum size of the flow path switching module is A, and satisfies: A > A1, and / or, A > A2, so that on the projection plane perpendicular to the axis of the first control valve, the axes of the first control valve, the second control valve, the third control valve and the fourth control valve are... The connection lines are non-rectangular. When the first, second, third, and fourth control valves are wrapped with damping adhesive or wet cloth, the contact area between the first, second, third, and fourth control valves and the damping adhesive or wet cloth can be increased. It is not necessary to wrap damping adhesive and wet cloth between two of the first, second, third, and fourth control valves, which facilitates the wrapping of damping adhesive and wet cloth, shortens the working time, and reduces the problem of excessive noise due to improper wrapping of damping adhesive and the problem of failure of the flow path switching module function due to overheating of welding.

When the first, second, third, and fourth control valves are wrapped with damping adhesive or wet cloth, the contact area between the first, second, third, and fourth control valves and the damping adhesive or wet cloth can be increased. It is not necessary to wrap damping adhesive and wet cloth between two of the first, second, third, and fourth control valves, which makes it easier to wrap damping adhesive and wet cloth, shortens the working time, and reduces the problem of excessive noise due to improper wrapping of damping adhesive and the problem of failure of flow path switching module function due to overheating of welding.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] The flow path switching module 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0028] like Figures 1-4 As shown, the flow path switching module 100 according to an embodiment of the present invention includes a first control valve 11, a second control valve 12, a third control valve 13 and a fourth control valve 14.

[0029] Specifically, the axes of the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14 are parallel and do not coincide. They are connected end-to-end in a ring. A first connection port 21 connects the first control valve 11 and the second control valve 12; a second connection port 22 connects the second control valve 12 and the third control valve 13; a third connection port 23 connects the third control valve 13 and the fourth control valve 14; and a fourth connection port 24 connects the first control valve 11 and the fourth control valve 14. All four connection ports (11, 22, 23, and 24) can be connected to the air conditioning system, allowing for flow path switching within the system.

[0030] The first control valve 11 and the second control valve 12 are arranged in the same direction as the third control valve 13 and the fourth control valve 14. It can be understood that on the projection plane perpendicular to the axis of the first control valve 11, the line connecting the axis of the first control valve 11 and the axis of the second control valve 12 is L1, and the line connecting the axis of the third control valve 13 and the axis of the fourth control valve 14 is L2. L1 and L2 are parallel or located on the same straight line.

[0031] In addition, along the arrangement direction of the first control valve 11 and the second control valve 12, the maximum distance between the first control valve 11 and the second control valve 12 is A1, the maximum distance between the third control valve 13 and the fourth control valve 14 is A2, the maximum size of the flow path switching module 100 is A, and satisfies: A > A1, and / or, A > A2.

[0032] It should be noted that the maximum distance between the first control valve 11 and the second control valve 12 is the distance between the sides of the first control valve 11 and the second control valve 12 that are away from each other, and the maximum distance between the third control valve 13 and the fourth control valve 14 is the maximum distance between the sides of the third control valve 13 and the fourth control valve 14 that are away from each other. Figures 1-4 In the example shown, along the arrangement direction of the first control valve 11 and the second control valve 12, the maximum size of the flow path switching module 100 is the distance from the side of the first control valve 11 away from the second control valve 12 to the side of the third control valve 13 away from the fourth control valve 14. Figures 5-8 In the example shown, along the arrangement direction of the first control valve 11 and the second control valve 12, the maximum size of the flow path switching module 100 is the distance between the third control valve 13 and the fourth control valve 14 on opposite sides of each other.

[0033] In related technologies, on a projection plane perpendicular to the axis of the first control valve, the line connecting the axes of the first control valve, the second control valve, the third control valve, and the fourth control valve forms a rectangle. When the first control valve, the second control valve, the third control valve, and the fourth control valve are wrapped with damping rubber or wet cloth, the contact area between the first control valve, the second control valve, the third control valve, and the fourth control valve and the damping rubber or wet cloth is small, resulting in poor damping and cooling effects of the flow path switching module. In order to improve the damping and cooling effects, it is necessary to wrap damping rubber and wet cloth between two of the first control valve, the second control valve, the third control valve, and the fourth control valve, which is inconvenient.

[0034] In this application, by making the maximum distance between the first control valve 11 and the second control valve 12 along the arrangement direction of the first control valve 11 and the second control valve 12 A1, the maximum distance between the third control valve 13 and the fourth control valve 14 A2, and the maximum size of the flow path switching module 100 A, and satisfying: A > A1, and / or, A > A2, it is possible to make the line connecting the axes of the first control valve 11, the second control valve 12, the third control valve 13 and the fourth control valve 14 on the projection plane perpendicular to the axis of the first control valve 11 non-rectangular, and the first control valve 11, the second control valve 12, the third control valve 13 and the fourth control valve 14 non-rectangular. When the second control valve 12, the third control valve 13, and the fourth control valve 14 are wrapped with damping adhesive or wet cloth, the contact area between the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14 and the damping adhesive or wet cloth can be increased. It is not necessary to wrap damping adhesive and wet cloth between two of the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14. This makes it easier to wrap the damping adhesive and wet cloth, shortens the working time, and reduces the problem of excessive noise caused by improper wrapping of damping adhesive, as well as the problem of failure of the flow path switching module 100 due to overheating during welding.

[0035] According to the flow path switching module 100 of this utility model embodiment, by making the maximum distance between the first control valve 11 and the second control valve 12 along the arrangement direction of the first control valve 11 and the second control valve 12 A1, the maximum distance between the third control valve 13 and the fourth control valve 14 A2, and the maximum size of the flow path switching module 100 A, and satisfying: A > A1, and / or, A > A2, it is possible to make the line connecting the axes of the first control valve 11, the second control valve 12, the third control valve 13 and the fourth control valve 14 non-rectangular on the projection plane perpendicular to the axis of the first control valve 11. When control valves 11, 12, 13, and 14 are wrapped with damping adhesive or wet cloth, the contact area between the control valves 11, 12, 13, and 14 and the damping adhesive or wet cloth can be increased. This eliminates the need to wrap damping adhesive and wet cloth between two valves in each of the control valves 11, 12, 13, and 14, making it easier to wrap the damping adhesive and wet cloth, shortening the working time, and reducing the problem of excessive noise due to improper wrapping of damping adhesive, as well as the problem of the flow path switching module 100 failing due to overheating during welding.

[0036] In some embodiments of this utility model, such as Figures 1-4 As shown, on the projection plane perpendicular to the axis of the first control valve 11, the line connecting the axis of the first control valve 11 and the axis of the second control valve 12 is L1, and the line connecting the axis of the third control valve 13 and the axis of the fourth control valve 14 is L2, wherein L1 is parallel to L2. This simplifies the structure of the flow path switching module 100, reduces its space requirements, and ensures that when the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14 are wrapped with damping adhesive or wet cloth, the contact area between these valves and the damping adhesive or wet cloth is increased. This ensures the damping and cooling effects of the flow path switching module 100, and eliminates the need to wrap damping adhesive and wet cloth between two valves in each of the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14. This facilitates the wrapping of damping adhesive and wet cloth, shortens the working time, and reduces the problem of excessive noise due to improper damping adhesive wrapping, as well as the problem of functional failure of the flow path switching module 100 due to overheating during welding.

[0037] Furthermore, such as Figures 1-4As shown, the length of L1 is equal to the length of L2. It can be understood that, on the projection plane perpendicular to the axis of the first control valve 11, the line connecting the axes of the first control valve 11, the second control valve 12, the third control valve 13 and the fourth control valve 14 forms a parallelogram. This further simplifies the structure of the flow path switching module 100, reduces its space occupation, and ensures that when the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14 are wrapped with damping adhesive or wet cloth, the contact area between the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14 and the damping adhesive or wet cloth can be increased. This ensures the damping and cooling effect of the flow path switching module 100, and eliminates the need to wrap damping adhesive and wet cloth between two of the valves in the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14. This facilitates the wrapping of damping adhesive and wet cloth, shortens the working time, and reduces the problem of excessive noise due to improper wrapping of damping adhesive and the problem of functional failure of the flow path switching module 100 due to overheating during welding.

[0038] In some other embodiments of this invention, the length of L1 is less than the length of L2. It is understood that, on a projection plane perpendicular to the axis of the first control valve 11, the line connecting the axes of the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14 forms a trapezoid. This simplifies the structure of the flow path switching module 100, reduces its space requirements, and ensures that when the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14 are wrapped with damping adhesive or wet cloth, the contact area between these valves and the damping adhesive or wet cloth is increased. This ensures the damping and cooling effects of the flow path switching module 100, and eliminates the need to wrap damping adhesive and wet cloth between two valves in each of the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14. This facilitates the wrapping of damping adhesive and wet cloth, shortens the working time, and reduces the problem of excessive noise due to improper damping adhesive wrapping, as well as the problem of functional failure of the flow path switching module 100 due to overheating during welding.

[0039] Furthermore, along the length of L1, i.e., along the arrangement direction of the first control valve 11 and the second control valve 12, L1 is located between the two ends of L2. This further simplifies the structure of the flow path switching module 100, reduces the space occupied by the flow path switching module 100, and ensures that when the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14 are wrapped with damping adhesive or wet cloth, the contact area between the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14 and the damping adhesive or wet cloth can be increased, ensuring the damping and cooling effect of the flow path switching module 100. It also eliminates the need to wrap damping adhesive and wet cloth between two of the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14, making it convenient to wrap damping adhesive and wet cloth, shortening the working time, and reducing the problem of excessive noise due to improper damping adhesive wrapping and the problem of functional failure of the flow path switching module 100 due to overheating during welding.

[0040] In some embodiments of this utility model, along the length direction of L1, that is, along the arrangement direction of the first control valve 11 and the second control valve 12, a portion of L1 overlaps with L2, wherein the length of L1 is equal to or unequal to the length of L2. This increases the structural diversity of the flow path switching module 100, simplifies its structure, reduces its space occupation, and ensures that when the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14 are wrapped with damping adhesive or wet cloth, the contact area between these valves and the damping adhesive or wet cloth is increased, guaranteeing the damping and cooling effects of the flow path switching module 100. Furthermore, it eliminates the need to wrap damping adhesive and wet cloth between two valves in each of the first, second, third, and fourth control valves, making the wrapping process easier, shortening the working time, and reducing the problem of excessive noise due to improper damping adhesive wrapping, as well as the problem of functional failure of the flow path switching module 100 due to overheating during welding.

[0041] In some embodiments of this utility model, L1 and L2 are spaced apart along the length direction of L1, that is, along the arrangement direction of the first control valve 11 and the second control valve 12, wherein the length of L1 may be equal to or unequal to the length of L2. It can be understood that the first control valve 11, the second control valve 12, the fourth control valve 14, and the third control valve 13 are arranged sequentially along the length direction of L1, that is, along the arrangement direction of the first control valve 11 and the second control valve 12. This increases the structural diversity of the flow path switching module 100, simplifies its structure, reduces its space occupation, and ensures that when the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14 are wrapped with damping adhesive or wet cloth, the contact area between these valves and the damping adhesive or wet cloth is increased, guaranteeing the damping and cooling effects of the flow path switching module 100. Furthermore, it eliminates the need to wrap damping adhesive and wet cloth between two valves in each of the first, second, third, and fourth control valves, making the wrapping process easier, shortening the working time, and reducing the problem of excessive noise due to improper damping adhesive wrapping, as well as the problem of functional failure of the flow path switching module 100 due to overheating during welding.

[0042] In some embodiments of this utility model, the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14 have the same axial length, and one axial end of the first control valve 11, one axial end of the second control valve 12, one axial end of the third control valve 13, and one axial end of the fourth control valve 14 are flush, and the other axial ends of the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14 are flush.

[0043] In some embodiments of this utility model, such as Figures 5-8As shown, on a projection plane perpendicular to the axis of the first control valve 11, the line connecting the axes of the first control valve 11 and the second control valve 12 is L1, and the line connecting the axes of the third control valve 13 and the fourth control valve 14 is L2. L1 and L2 are on the same straight line. It can be understood that the axes of the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14 are located in the same plane. Therefore, when wrapping the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14 with damping adhesive or wet cloth, the contact area between the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14 and the damping adhesive or wet cloth can be further increased. This ensures the damping and cooling effect of the flow path switching module 100, and eliminates the need to wrap damping adhesive and wet cloth between two valves in the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14. This facilitates wrapping the damping adhesive and wet cloth, shortens the working time, and reduces the problem of excessive noise due to improper wrapping of damping adhesive, as well as the problem of functional failure of the flow path switching module 100 due to overheating during welding.

[0044] In some embodiments of this utility model, such as Figures 5-8 As shown, the first control valve 11 and the second control valve 12 are located between the third control valve 13 and the fourth control valve 14. This facilitates the interconnection between the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14, and makes it easier for the axes of the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14 to be arranged in the same plane. Therefore, when the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14 are wrapped with damping adhesive or wet cloth, the contact area between them and the damping adhesive or wet cloth can be further increased. This ensures the damping and cooling effect of the flow path switching module 100, and eliminates the need to wrap damping adhesive and wet cloth between any two valves in the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14. This simplifies the process of wrapping the damping adhesive and wet cloth, shortens the working time, and reduces the problem of excessive noise due to improper damping adhesive wrapping, as well as the problem of functional failure of the flow path switching module 100 due to overheating during welding.

[0045] In some embodiments of this utility model, such as Figures 5-8As shown, the lengths of the first control valve 11 and the second control valve 12 are shorter than the lengths of the third control valve 13 and the fourth control valve 14. This facilitates the arrangement of the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14 on the same plane. Therefore, when wrapping the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14 with damping adhesive or wet cloth, the contact area between these valves can be further increased. This ensures the damping and cooling effects of the flow path switching module 100, and eliminates the need to wrap damping adhesive and wet cloth between any two valves in the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14. This simplifies the wrapping process, shortens the working time, and reduces the problem of excessive noise due to improper damping adhesive wrapping, as well as the problem of functional failure of the flow path switching module 100 due to overheating during welding.

[0046] In some embodiments of this utility model, such as Figure 1 and Figure 5 As shown, the first control valve 11 and the second control valve 12 are connected by the first connecting pipe 31, and the first connection port 21 is provided on the first connecting pipe 31, thereby facilitating the connection between the first control valve 11 and the second control valve 12.

[0047] Optionally, the first connecting pipe 31 is a Y-shaped pipe with three ports. Two of the three ports are connected to one end of the first control valve 11 and one end of the second control valve 12, and the remaining port is formed as the first connecting port 21.

[0048] In some embodiments of this utility model, such as Figure 1 and Figure 5 As shown, the second control valve 12 and the third control valve 13 are connected by the second connecting pipe 32, and the second connecting port 22 is provided on the first connecting pipe 31, thereby facilitating the connection between the second control valve 12 and the third control valve 13.

[0049] Optionally, the second connecting pipe 32 is a Y-shaped pipe with three ports. Two of the three ports are connected to the other end of the second control valve 12 and one end of the third control valve 13, and the remaining port is formed as the second connecting port 22.

[0050] In some embodiments of this utility model, such as Figure 1 and Figure 5 As shown, the third control valve 13 and the fourth control valve 14 are connected by the third connecting pipe 33, and the third connecting port 23 is provided on the third connecting pipe 33, thereby facilitating the connection between the third control valve 13 and the fourth control valve 14.

[0051] Optionally, the third connecting pipe 33 is a Y-shaped pipe with three ports. Two of the three ports are connected to the other end of the third control valve 13 and one end of the fourth control valve 14, and the remaining port is formed as the third connecting port 23.

[0052] In some embodiments of this utility model, such as Figure 1 and Figure 5 As shown, the first control valve 11 and the fourth control valve 14 are connected by a fourth connecting pipe 34, and the fourth connecting port 24 is provided on the fourth connecting pipe 34, thereby facilitating the connection between the first control valve 11 and the fourth control valve 14.

[0055] For example, in a specific example, the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14 are one-way valves. The first control valve 11 only allows refrigerant to flow from the second connection port 22 to the first connection port 21, the second control valve 12 only allows refrigerant to flow from the third connection port 23 to the second connection port 22, the third control valve 13 only allows refrigerant to flow from the third connection port 23 to the fourth connection port 24, and the fourth control valve 14 only allows refrigerant to flow from the fourth connection port 24 to the first connection port 21.

[0057] The following describes an air conditioning system according to an embodiment of the present invention.

[0058] The air conditioning system according to an embodiment of the present invention includes the flow path switching module 100 described above.

[0059] According to the air conditioning system of this utility model embodiment, by setting the above-mentioned flow path switching module 100, not only can the flow path be switched, but also the maximum distance between the first control valve 11 and the second control valve 12 along the arrangement direction of the first control valve 11 and the second control valve 12 is A1, the maximum distance between the third control valve 13 and the fourth control valve 14 is A2, the maximum size of the flow path switching module 100 is A, and satisfies: A > A1, and / or, A > A2, so that on the projection plane perpendicular to the axis of the first control valve 11, the axes of the first control valve 11, the second control valve 12, the third control valve 13 and the fourth control valve 14 are... The connection lines are non-rectangular. When the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14 are wrapped with damping adhesive or wet cloth, the contact area between the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14 and the damping adhesive or wet cloth can be increased. It is not necessary to wrap damping adhesive and wet cloth between two valves in the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14. This makes it convenient to wrap damping adhesive and wet cloth, shortens the working time, and reduces the problem of excessive noise caused by improper wrapping of damping adhesive and the problem of failure of the flow path switching module 100 due to overheating of welding.

[0060] In some embodiments of this utility model, the air conditioning system may further include a compressor, a four-way valve, an indoor heat exchanger, an outdoor heat exchanger, and a throttling device. The compressor has an exhaust port and a return port. The four-way valve has a first port, a second port, a third port, and a fourth port. The first port is connected to one of the second and fourth ports, and the third port is connected to the other of the second and fourth ports. The exhaust port is connected to the first port, and the return port is connected to the third port. One end of the indoor heat exchanger is connected to the second port, and one end of the outdoor heat exchanger is connected to the fourth port. A second connection port 22 is connected to the other end of the indoor heat exchanger, and a fourth connection port 24 is connected to the other end of the outdoor heat exchanger. The first connection port 21 and the third connection port 23 are connected. The throttling device is located between the first connection port 21 and the third connection port 23. Additionally, a modular radiator for cooling the electrical control box may be provided between the first connection port 21 and the third connection port 23, and the throttling device is located between the modular radiator and the third connection port 23.

[0061] During the actual operation of the air conditioning system, when the system is in cooling mode, the compressor compresses the refrigerant into a high-temperature, high-pressure gas. The high-pressure gaseous refrigerant flows to the outdoor heat exchanger through the compressor's exhaust port, the first port of the four-way valve, and the fourth port. The outdoor heat exchanger exchanges heat with the external environment, condensing and dissipating heat. The refrigerant flows within the outdoor heat exchanger and releases heat to the external environment, thus changing from a gaseous state to a liquid state. Then, the high-pressure liquid refrigerant flowing out of the outdoor heat exchanger enters the flow path switching module 100 through the fourth connection port 24. At this time, the fourth control valve 14 controls the connection between the first connection port 21 and the fourth connection port 24, allowing the refrigerant to flow from the fourth connection port 24 to the first connection port 21. The refrigerant flows from the first connection port 21 through the module radiator and exchanges heat with the electrical control box, and then flows to the throttling device. The throttling device can reduce the pressure of the refrigerant, and then the low-pressure liquid refrigerant returns to the flow path switching module 100 through the third connection port 23.

[0062] At this time, the second control valve 12 controls the connection between the second connection port 22 and the third connection port 23, the first control valve 11 controls the disconnection between the first connection port 21 and the second connection port 22, and the fourth connection port 24 controls the disconnection between the third connection port 23 and the fourth connection port 24. Thus, the refrigerant flows from the third connection port 23 through the second control valve 12 and then out of the second connection port 22 into the flow path switching module 100 and flows to the indoor heat exchanger. The indoor heat exchanger absorbs heat, and the refrigerant vaporizes inside, changing from a liquid to a gaseous state, thereby carrying away the heat from the airflow flowing across the surface of the indoor heat exchanger. The low-temperature airflow is then delivered into the room by the indoor unit of the air conditioner to achieve the purpose of cooling. Simultaneously, the low-pressure gaseous refrigerant flows to the second port of the four-way valve and then from the third port to the return port to return to the compressor for compression again, thus forming a refrigerant cycle and achieving the cooling effect of the air conditioning system.

[0063] Similarly, when the air conditioning system is in heating mode, the compressor compresses the refrigerant into a high-temperature, high-pressure gas. The high-pressure gaseous refrigerant flows through the compressor's exhaust port, the first port and the second port of the four-way valve to the indoor heat exchanger. The indoor heat exchanger exchanges heat with the airflow flowing across its surface. The airflow absorbs heat, the refrigerant condenses and dissipates heat, and the high-temperature airflow is delivered into the room by the indoor unit to achieve the purpose of heating. The refrigerant flows within the indoor heat exchanger and releases heat into the indoor environment, thus changing from a gaseous state to a liquid state. Then, the high-pressure liquid refrigerant flowing out of the indoor heat exchanger enters the flow path switching module 100 through the second connection port 22. At this time, the first control valve 11 controls the first connection port 21 to connect with the second connection port 22, so that the refrigerant flows from the second connection port 22 to the first connection port 21. The refrigerant flows from the first connection port 21 through the module heat exchanger and the electrical control box, and then flows to the throttling device. The throttling device can play a throttling role and reduce the pressure of the refrigerant. Subsequently, the low-pressure liquid refrigerant returns to the flow path switching module 100 from the third connection port 23.

[0064] At this time, the third control valve 13 controls the connection between the third connection port 23 and the fourth connection port 24, the second control valve 12 controls the disconnection between the second connection port 22 and the third connection port 23, and the fourth connection port 24 controls the disconnection between the third connection port 23 and the fourth connection port 24. Thus, the refrigerant flows from the third connection port 23 through the third control valve 13 and out of the flow path switching module 100 via the fourth connection port 24, flowing towards the outdoor heat exchanger. The outdoor heat exchanger absorbs heat. The refrigerant is heated and vaporized within the outdoor heat exchanger, changing from a liquid to a gaseous state, thereby carrying away the heat flowing through the outdoor environment. The low-pressure gaseous refrigerant flows to the fourth port of the four-way valve and then from the third port to the return port to return to the compressor for further compression, thus forming a refrigerant cycle and achieving the heating effect of the air conditioning system.

[0066] The air conditioner according to an embodiment of the present invention includes the air conditioning system described above.

[0067] According to the air conditioner of this utility model embodiment, by setting the above-described air conditioning system, the maximum distance between the first control valve 11 and the second control valve 12 along the arrangement direction of the first control valve 11 and the second control valve 12 is A1, the maximum distance between the third control valve 13 and the fourth control valve 14 is A2, and the maximum size of the flow path switching module 100 is A, and satisfies: A > A1, and / or, A > A2, so that on the projection plane perpendicular to the axis of the first control valve 11, the line connecting the axes of the first control valve 11, the second control valve 12, the third control valve 13 and the fourth control valve 14 forms a non-rectangular shape. When the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14 are wrapped with damping adhesive or wet cloth, the contact area between the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14 and the damping adhesive or wet cloth can be increased. It is not necessary to wrap damping adhesive and wet cloth between two of the valves in the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14, which makes it convenient to wrap damping adhesive and wet cloth, shortens the working time, and at the same time reduces the problem of excessive noise caused by improper wrapping of damping adhesive and reduces the problem of failure of the flow path switching module 100 due to overheating of welding.
