For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0050] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0051] The following is combined with Figures 1-4 The present invention describes a transmission pipe assembly for an air conditioning system and an air conditioning system.

[0052] According to an embodiment of the first aspect of the present invention, referring to Figures 1-4 As shown, the transmission pipe assembly for an air conditioning system provided by the present invention mainly includes: a transmission pipe 1, a first conductive component 2, and a second conductive component 3. The transmission pipe 1 has a hollow structure; the first conductive component 2 and the second conductive component 3 have opposite polarities to facilitate the formation of an electrical circuit for transmitting power signals and carrier communication signals. For example, the first conductive component 2 has a positive polarity, and the second conductive component 3 has a negative polarity.

[0053] Furthermore, the first conductive component 2 and the second conductive component 3 are arranged side by side and spaced apart along the axial direction of the transmission pipe 1 to separate the first cavity 4, the second cavity 5 and the insulating cavity 6. The first cavity 4 is used to transmit gaseous refrigerant, the second cavity 5 is used to transmit liquid refrigerant, and the insulating cavity 6 is located between the first cavity 4 and the second cavity 5 to insulate and isolate the first conductive component 2 and the second conductive component 3, thereby preventing short circuit and fire and ensuring safety and reliability.

[0054] For example, such as Figure 1 As shown, the first conductive component 2 and the second conductive component 3 are arranged horizontally inside the transmission tube 1, separating the upper first cavity 4, the middle insulating cavity 6, and the lower second cavity 5 in sequence. The first conductive component 2 and the second conductive component 3 can transmit AC mains power or 310V DC power according to actual needs. The insulating cavity 6 can be a vacuum cavity.

[0055] It is understandable that the first cavity 4 and the second cavity 5 have open ends to facilitate the circulation and transfer of refrigerant with the indoor and outdoor units of the air conditioning system, while the insulating cavity 6 has closed ends to facilitate the formation of a vacuum cavity.

[0056] Therefore, the transmission pipe assembly for air conditioning systems provided in this embodiment of the invention can simultaneously transmit refrigerant, power signals, and communication signals without interfering with each other. It has at least three functions, achieving the effect of one pipe serving multiple purposes. This can effectively reduce the number of pipes in the air conditioning system, simplify the system structure, reduce costs, facilitate implementation and installation, and improve implementability. It is also less prone to connection errors and effectively reduces the risk of installation and implementation.

[0057] According to one embodiment of the present invention, referring to Figure 2 As shown, the first conductive component 2 is provided with a first insulating component 7 between the left and right sides of the transmission pipe 1 along the radial direction of the transmission pipe 1 and the pipe wall of the transmission pipe 1; the second conductive component 3 is provided with a second insulating component 8 between the left and right sides of the transmission pipe 1 along the radial direction of the transmission pipe 1 and the pipe wall of the transmission pipe 1.

[0058] Since the refrigerant transmission pipes in air conditioning systems are generally made of metal, such as copper, they are highly conductive. Therefore, this embodiment of the invention effectively isolates the electrical connection between the conductive component and the transmission pipe 1 by providing insulating components on both sides of the conductive component, achieving an insulation effect and thus ensuring safety and reliability.

[0059] According to one embodiment of the present invention, referring to Figure 2 As shown, at least one first insulating component 7 has a hollow structure to form a first wire passage 9, and at least one second insulating component 8 has a hollow structure to form a second wire passage 10; furthermore, the transmission pipe 1 has a first wire passage hole 11 on the pipe wall corresponding to the first wire passage 9, and the first wire passage hole 11 communicates with the first wire passage 9; the transmission pipe 1 has a second wire passage hole 12 on the pipe wall corresponding to the second wire passage 10, and the second wire passage hole 12 communicates with the second wire passage 10.

[0060] For example, both ends of the transmission pipe 1 are provided with a first wire passage hole 11 and a second wire passage hole 12; the signal transmission line of the outdoor unit 14 of the outdoor unit can be extended into the first wire passage channel 9 and the second wire passage channel 10 through the first wire passage hole 11 and the second wire passage hole 12 at one end, respectively, and electrically connected to the ends of the first conductive component 2 and the second conductive component 3, thereby realizing the transmission of power signals and carrier communication signals.

[0061] Similarly, the signal receiving line of the indoor unit's indoor control unit 25 can extend into the first wire passage 9 and the second wire passage 10 through the first wire passage hole 11 and the second wire passage hole 12 at the other end, and be electrically connected to the ends of the first conductive component 2 and the second conductive component 3, thereby realizing the reception of power signals and carrier communication signals.

[0062] It is worth mentioning that, during wiring, if the signal transmitting line and the signal receiving line are connected to the first conductive component 2 and the second conductive component 3 via the first cavity 4 and the second cavity 5 respectively, the signal transmitting line and the signal receiving line may obstruct the flow of the refrigerant during the refrigerant transmission process, resulting in poor heat exchange effect; if the signal transmitting line and the signal receiving line are connected to the first conductive component 2 and the second conductive component 3 via the insulating cavity 6 respectively, the vacuum insulation effect may be affected, leading to short circuit, which poses a safety risk and is more difficult to process.

[0063] Therefore, the embodiments of the present invention cleverly utilize insulating components and route the wiring inside the insulating components. On the one hand, this ensures the transmission and reception of signals, and on the other hand, it avoids obstructing the flow of refrigerant in the first cavity 4 and the second cavity 5, and avoids affecting the insulation effect of the insulating cavity 6, which facilitates production and processing.

[0064] According to one embodiment of the present invention, the first conductive component 2, the second conductive component 3, the first insulating component 7, the second insulating component 8 and the transmission tube 1 are integrally formed, which is beneficial to production and processing.

[0065] According to one embodiment of the present invention, the transmission tube 1 is a copper tube, and the first conductive component 2 and the second conductive component 3 are copper sheets. The copper tube is used for power line carrier communication transmission, which improves the heat exchange effect of the refrigerant while ensuring signal transmission.

[0066] Of course, the first conductive component 2 and the second conductive component 3 can also be conductive structures such as live wire and neutral wire.

[0067] The specific material of the insulating component of this invention is not particularly limited. For example, it can be made of plastic or other materials, and the design can be tailored to actual needs.

[0068] According to one embodiment of the present invention, referring to Figure 1 , Figure 3 and Figure 4 As shown, the first cavity 4 and the second cavity 5 are respectively provided with a transfer pipe 13 at both ends. The transfer pipe 13 located at the first end of the first cavity 4 and the second cavity 5 is used to connect to the outdoor unit of the air conditioning system, and the transfer pipe 13 located at the second end of the first cavity 4 and the second cavity 5 is used to connect to the indoor unit of the air conditioning system to form a refrigerant circulation pipeline, thereby ensuring the refrigerant circulation flow.

[0069] For example, the adapter pipe 13 at the first end of the first cavity 4 is connected to the compressor 21 of the outdoor unit, the adapter pipe 13 at the first end of the second cavity 5 is connected to the throttle valve 23 of the outdoor unit, and the adapter pipe 13 at the second end of the first cavity 4 and the second cavity 5 is connected to both ends of the evaporator 30 of the indoor unit.

[0070] According to one embodiment of the present invention, the adapter pipe 13 is an insulating pipe to prevent electrical signals from being transmitted to components such as the evaporator 30 of the indoor unit, thereby ensuring safety.

[0071] According to one embodiment of the present invention, referring to Figures 2-4 As shown, the first end of the adapter pipe 13 has an arched cross-sectional shape, and correspondingly, the first cavity 4 and the second cavity 5 have arched cross-sectional shapes, enabling quick docking between the transmission pipe 1 and the adapter pipe 13. Furthermore, since the refrigerant pipes of the air conditioning system are generally round pipes and cannot be adjusted, the present invention designs the second end of the adapter pipe 13 to have a circular cross-sectional shape, which enables quick docking between the adapter pipe 13 and components such as the compressor 21, the throttle valve 23, and the evaporator 30.

[0072] According to an embodiment of the second aspect of the present invention, referring to Figure 4As shown, the present invention also provides an air conditioning system, mainly comprising: an outdoor unit, an indoor unit, and a transmission pipe assembly for the air conditioning system described in the above embodiment. The outdoor unit and the indoor unit are cyclically connected through the transmission pipe assembly, thereby realizing the cyclic transmission of refrigerant. The outdoor unit is adapted to send power signals and carrier communication signals to the first conductive component 2 and the second conductive component 3; the indoor unit is adapted to receive power signals and carrier communication signals via the first conductive component 2 and the second conductive component 3, thereby realizing the transmission of power signals and carrier communication signals and achieving communication between the indoor unit and the outdoor unit. It can be understood that a signal circuit is formed between the outdoor unit, the first conductive component 2, the second conductive component 3, and the indoor unit, thereby realizing signal transmission.

[0073] Therefore, the air conditioning system provided in this embodiment of the invention can simultaneously transmit refrigerant, power signals and communication signals through the transmission pipe assembly, achieving the purpose of multiple uses for one pipe. This can effectively reduce the number of pipes in the air conditioning system, simplify the system structure, reduce costs, facilitate implementation and installation, and has higher implementability, making it less prone to connection errors and effectively reducing the risk of installation and implementation.

Specifically, the switching circuit 17 can be connected to the first conductive component 2 and the second conductive component 3 via two power signal lines respectively, used to send power signals.

[0075] The signal modulation circuit 18 is connected to the first controller 16, the first conductive component 2, and the second conductive component 3 respectively. Specifically, the signal modulation circuit 18 can be connected to the first conductive component 2 and the second conductive component 3 via two communication signal lines to transmit carrier communication signals.

[0076] Furthermore, a first capacitor 19 is provided between the signal modulation circuit 18 and the first conductive component 2, and a second capacitor 20 is provided between the signal modulation circuit 18 and the second conductive component 3. Specifically, the first capacitor 19 and the second capacitor 20 can be respectively disposed in the two communication signal lines. This design can isolate signal interference, thereby effectively improving communication quality.

[0077] In addition, the outdoor unit also includes components such as a compressor 21, a condenser 22, a throttle valve 23, and an outdoor fan 24. The compressor 21 is connected to the first end of the first cavity 4 of the transmission pipe 1 via a transfer pipe 13. The throttle valve 23 is connected to the first end of the second cavity 5 of the transmission pipe 1 via a transfer pipe 13. The condenser 22 is connected between the compressor 21 and the throttle valve 23. The outdoor fan 24 is arranged side by side on the condenser 22. The first controller 16 is electrically connected to the compressor 21, the throttle valve 23, and the outdoor fan 24 respectively. It can control the operating frequency of the compressor 21, the opening degree of the throttle valve 23, and the speed of the outdoor fan 24, thereby adjusting the heat exchange effect.

[0078] According to one embodiment of the present invention, referring to Figure 4 As shown, the indoor unit mainly includes: an indoor control unit 25, which includes: a signal isolation module 26, a signal parsing circuit 27, a power supply circuit 28, and a second controller 29. The signal isolation module 26 can be connected to the first conductive component 2 and the second conductive component 3 via two signal receiving lines respectively, for receiving and isolating power signals and carrier communication signals, thus separating the power signals and carrier communication signals. The signal parsing circuit 27 is connected to the signal isolation module 26 and is used to parse the isolated carrier communication signal. The power supply circuit 28 is connected to the signal isolation module 26 and is used to receive the isolated power signal. The second controller 29 is connected to both the signal parsing circuit 27 and the power supply circuit 28, for receiving the parsed communication signal and voltage, thereby achieving simultaneous power supply and communication.

[0079] Furthermore, the indoor unit also includes components such as an evaporator 30 and an indoor fan 31. The two ends of the evaporator 30 are connected to the second ends of the first cavity 4 and the second cavity 5 of the transmission pipe 1 via the adapter pipe 13, respectively. The indoor fan 31 is arranged side by side on the evaporator 30. The second controller 29 is connected to the indoor fan 31 and can control the speed of the indoor fan 31, thereby adjusting the heat exchange effect.

[0080] The working principle of the air conditioning system provided by the present invention is described below, mainly including: the refrigerant transmission process and the signal transmission process.

[0081] (1) Refrigerant transfer: In refrigeration mode, the gaseous refrigerant generated by the compressor 21 is condensed and released by the condenser 22, and then becomes liquid refrigerant after being throttled by the expansion valve 23. Then, it flows into the evaporator 30 to absorb heat and evaporate through the transfer pipe 13 and the second cavity 5 of the transmission pipe 1. The evaporated gaseous refrigerant flows back to the compressor 21 through the transfer pipe 13 and the first cavity 4 of the transmission pipe 1.

[0082] In heating mode, the gaseous refrigerant generated by the compressor 21 flows into the evaporator 30 through the transfer pipe 13 and the first chamber 4 of the transmission pipe 1 to condense and release heat. The condensed liquid refrigerant flows into the expansion valve 23 through the transfer pipe 13 and the second chamber 5 of the transmission pipe 1, and then absorbs heat and evaporates through the condenser 22. The evaporated gaseous refrigerant flows back to the compressor 21.

[0083] (2) Signal transmission: The first controller 16 controls the switching circuit 17 and the signal modulation circuit 18 to send power signals and carrier communication signals to the first conductive component 2 and the second conductive component 3 respectively; then the power signal and carrier communication signal are received by the signal isolation module 26 and isolated and separated, so that the power signal enters the power supply circuit 28 and the carrier communication signal enters the signal parsing circuit 27. The power supply circuit 28 outputs a specified voltage value signal to the second controller 29. After parsing, the carrier communication signal is transmitted to the second controller 29, thereby realizing the communication between the indoor unit and the outdoor unit.

[0084] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
