[0003] The present application relates to the technical field of air conditioning, and in particular to a transmission pipe assembly for an air conditioning system and an air conditioning system. Background Art

[0004] In the related art, both cooling and heating of air-conditioning systems require the participation of refrigerant media. Gaseous refrigerant and liquid refrigerant are circulated in copper pipes to achieve temperature regulation. In addition, the normal operation of the air-conditioning system is inseparable from the power supply. Therefore, the air-conditioning system needs to deploy power cables, generally using twisted pair cables to transmit AC power to drive components such as the compressor or fan of the air-conditioning system. At the same time, the air-conditioning system also needs to deploy communication cables for cascading equipment within the air-conditioning system to achieve networking effects. Therefore, during the installation process of the air-conditioning system, multiple pipelines such as refrigerant pipelines, power cables, and communication cables need to be laid out, which is very costly. In addition, the complex wiring environment poses great challenges to manual deployment and is difficult to install. If the power cables and communication cables are connected incorrectly, it will also cause damage to the air-conditioning system.

[0044] The transmission pipe assembly for the air conditioning system and the air conditioning system of the present application are described below with reference to FIG. 1 to FIG. 4 .

[0045] According to an embodiment of the first aspect of the present application, as shown in Figures 1-4 , a transmission pipe assembly for an air conditioning system provided herein primarily comprises: a transmission pipe 1, a first conductive component 2, and a second conductive component 3. The transmission pipe 1 is hollow; the first conductive component 2 and the second conductive component 3 have opposite electrical polarities, thereby forming an electrical circuit for transmitting power signals and carrier communication signals. For example, the first conductive component 2 has a positive electrical polarity, while the second conductive component 3 has a negative electrical polarity.

[0046] In addition, the first conductive component 2 and the second conductive component 3 are arranged side by side and spaced apart in the transmission tube 1 along the axial direction of the transmission tube 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, and the second cavity 5 is used to transmit liquid refrigerant. The insulating cavity 6 is located between the first cavity 4 and the second cavity 5, and is used to insulate and isolate the first conductive component 2 and the second conductive component 3 to avoid short circuit and fire, thereby ensuring safety and reliability.

[0047] For example, as shown in Figure 1, the first conductive component 2 and the second conductive component 3 are arranged horizontally in the transmission tube 1 from top to bottom, and are separated into an upper first cavity 4, a middle insulating cavity 6 and a 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.

[0048] It can be understood that both ends of the first cavity 4 and the second cavity 5 are open structures to facilitate the circulation of refrigerant with the indoor and outdoor units of the air-conditioning system, and both ends of the insulating cavity 6 are closed structures to form a vacuum cavity.

[0049] Therefore, the transmission pipe assembly for the air-conditioning system provided in the embodiment of the present application can realize the simultaneous transmission of refrigerant, power signals and communication signals without affecting each other. It has at least three functions and achieves the effect of one pipe for multiple uses, thereby effectively reducing the number of pipelines in the air-conditioning system, simplifying the system structure, reducing costs, facilitating implementation and installation, and is more feasible, less prone to connection errors, and effectively reducing the risk of installation implementation.

[0050] According to one embodiment of the present application, as shown in Figure 2, first insulating components 7 are respectively provided between the first conductive component 2 and the tube wall of the transmission tube 1 on the left and right sides along the radial direction of the transmission tube 1; second insulating components 8 are respectively provided between the second conductive component 3 and the tube wall of the transmission tube 1 on the left and right sides along the radial direction of the transmission tube 1.

[0051] Since the refrigerant transmission pipes of air conditioning systems are generally metal pipes, such as copper pipes, which are easily conductive, the embodiment of the present application provides insulating components on both sides of the conductive component to effectively isolate the electrical connection between the conductive component and the transmission pipe 1, achieving an insulating effect and thus ensuring safety and reliability.

[0052] According to one embodiment of the present application, as shown in Figure 2, at least one first insulating component 7 is a hollow structure to construct a first wire passing channel 9, and at least one second insulating component 8 is a hollow structure to construct a second wire passing channel 10; and, a first wire passing hole 11 is provided on the tube wall of the transmission tube 1 corresponding to the first wire passing channel 9, and the first wire passing hole 11 is connected to the first wire passing channel 9; a second wire passing hole 12 is provided on the tube wall of the transmission tube 1 corresponding to the second wire passing channel 10, and the second wire passing hole 12 is connected to the second wire passing channel 10.

[0053] For example, both ends of the transmission pipe 1 are provided with a first wire hole 11 and a second wire hole 12; the signal sending line of the outdoor control unit 14 of the outdoor unit can extend into the first wire channel 9 and the second wire channel 10 respectively through the first wire hole 11 and the second wire hole 12 at one end, and be 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.

[0054] Similarly, the signal receiving line of the indoor control unit 25 of the indoor unit can extend into the first wire channel 9 and the second wire channel 10 respectively through the first wire hole 11 and the second wire 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.

[0055] It is worth mentioning that when wiring, if the signal sending line and the signal receiving line are connected to the first conductive component 2 and the second conductive component 3 respectively through the first cavity 4 and the second cavity 5, during the refrigerant transmission process, the signal sending line and the signal receiving line are likely to hinder the flow of refrigerant, resulting in poor heat exchange effect; if the signal sending line and the signal receiving line are connected to the first conductive component 2 and the second conductive component 3 respectively through the insulating cavity 6, it is easy to affect the vacuum insulation effect, resulting in a short circuit, which poses a safety risk and is more difficult to process.

[0056] Therefore, the embodiment of the present application cleverly utilizes insulating components and routes the wiring inside the insulating components. On the one hand, it can ensure the sending and receiving of signals. On the other hand, it can avoid obstructing the flow of refrigerant in the first cavity 4 and the second cavity 5, and avoid affecting the insulation effect of the insulating cavity 6, thereby facilitating production and processing.

[0057] According to one embodiment of the present application, 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 an integrally formed structure, which is convenient for production and processing.

[0058] According to one embodiment of the present application, the transmission tube 1 is a copper tube, the first conductive component 2 and the second conductive component 3 are copper sheets, and the copper tube is used for power line carrier communication transmission, which improves the refrigerant heat exchange effect while ensuring signal transmission.

[0059] Of course, the first conductive component 2 and the second conductive component 3 may also be conductive structures such as a live wire and a neutral wire.

[0060] There is no particular restriction on the specific material of the insulating component of the present application. For example, it can be made of plastic or other materials, and can be designed according to actual needs.

[0061] According to one embodiment of the present application, as shown in Figures 1, 3 and 4, transfer pipes 13 are respectively provided at both ends of the first cavity 4 and the second cavity 5, and the transfer pipes 13 located at the first ends of the first cavity 4 and the second cavity 5 are used to be connected to the outdoor unit of the air-conditioning system, and the transfer pipes 13 located at the second ends of the first cavity 4 and the second cavity 5 are used to be connected to the indoor unit of the air-conditioning system to form a refrigerant circulation pipeline, thereby ensuring the circulation of the refrigerant.

[0062] For example, the transfer tube 13 at the first end of the first cavity 4 is connected to the compressor 21 of the outdoor unit, the transfer tube 13 at the first end of the second cavity 5 is connected to the throttle valve 23 of the outdoor unit, and the transfer tube 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.

[0063] According to one embodiment of the present application, the transfer tube 13 is an insulating tube, which is used to prevent the electrical signal from being transmitted to the evaporator 30 and other components of the indoor unit, thereby ensuring safety.

[0064] According to one embodiment of the present application, as shown in Figures 2 to 4, the cross-sectional shape of the first end of the transfer tube 13 is arched, and accordingly, the cross-sectional shape of the first cavity 4 and the second cavity 5 is arched, thereby realizing rapid docking of the transmission tube 1 and the transfer tube 13; and, since the refrigerant pipeline of the air-conditioning system is generally a round tube and cannot be adjusted, the present application designs the cross-sectional shape of the second end of the transfer tube 13 to be circular, which can realize rapid docking of the transfer tube 13 with components such as the compressor 21, the throttle valve 23 and the evaporator 30.

[0065] According to an embodiment of the second aspect of the present application, as shown in FIG4 , the present application further provides an air conditioning system, primarily comprising: an outdoor unit, an indoor unit, and a transmission pipe assembly for an air conditioning system according to the above-described embodiment. The outdoor unit and the indoor unit are cyclically connected via the transmission pipe assembly, thereby achieving refrigerant circulation transmission. The outdoor unit is adapted to transmit a power signal and a carrier communication signal to the first conductive component 2 and the second conductive component 3 ; the indoor unit is adapted to receive the power signal and the carrier communication signal via the first conductive component 2 and the second conductive component 3 , thereby achieving transmission of the power signal and the carrier communication signal and enabling communication between the indoor unit and the outdoor unit. It will be understood that a signal electrical circuit is formed between the outdoor unit, the first conductive component 2 , the second conductive component 3 , and the indoor unit, thereby achieving signal transmission.

[0066] Therefore, the air-conditioning system provided in the embodiment of the present application can realize the simultaneous transmission of refrigerant, power signals and communication signals through the transmission pipe assembly, thereby achieving the purpose of multiple uses of one pipe, thereby effectively reducing the number of pipelines in the air-conditioning system, simplifying the system structure, reducing costs, facilitating implementation and installation, and having higher feasibility, less prone to connection errors, and effectively reducing the risk of installation implementation.

[0067] According to one embodiment of the present application, as shown in FIG4 , the outdoor unit primarily includes an outdoor control unit 14, which includes a power supply 15, a first controller 16, a switching circuit 17, and a signal modulation circuit 18.

The switching circuit 17 is respectively connected to the first controller 16, the first conductive component 2, and the second conductive component 3. 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, for transmitting power signals.

[0068] 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 respectively via two communication signal lines for sending carrier communication signals.

[0069] 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 provided in the two communication signal lines. This design can isolate signal interference, thereby effectively improving communication quality.

[0070] In addition, the outdoor unit also includes: a compressor 21, a condenser 22, a throttle valve 23 and an outdoor fan 24 and other components. The compressor 21 is connected to the first end of the first cavity 4 of the transmission pipe 1 through the transfer tube 13, and the throttle valve 23 is connected to the first end of the second cavity 5 of the transmission pipe 1 through the transfer tube 13, and the condenser 22 is connected between the compressor 21 and the throttle valve 23, and the outdoor fan 24 is arranged side by side with the condenser 22; the first controller 16 is electrically connected to the compressor 21, the throttle valve 23 and the outdoor fan 24 respectively, and can control the operating parameters such as the operating frequency of the compressor 21, the opening of the throttle valve 23 and the speed of the outdoor fan 24, thereby adjusting the heat exchange effect.

[0071] According to one embodiment of the present application, as shown in FIG4 , the indoor unit mainly includes: an indoor control unit 25, which includes: a signal isolation module 26, a signal analysis 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 the power supply signal and the carrier communication signal, thereby isolating the power supply signal from the carrier communication signal; the signal analysis circuit 27 is connected to the signal isolation module 26, for analyzing the isolated carrier communication signal; the power supply circuit 28 is connected to the signal isolation module 26, for receiving the isolated power supply signal; and the second controller 29 is connected to the signal analysis circuit 27 and the power supply circuit 28, respectively, for receiving the analyzed communication signal and voltage, thereby achieving simultaneous power supply and communication.

[0072] In addition, the indoor unit also includes: an evaporator 30 and an indoor fan 31 and other components. The two ends of the evaporator 30 are respectively connected to the second ends of the first cavity 4 and the second cavity 5 of the transmission tube 1 through the transfer tube 13. The indoor fan 31 is arranged side by side with the evaporator 30. The second controller 29 is connected to the indoor fan 31, which can control the speed of the indoor fan 31, thereby adjusting the heat exchange effect.

[0073] The working principle of the air-conditioning system provided in this application is described below, mainly including the refrigerant transmission process and the signal transmission process.

[0074] (1) Refrigerant transmission: In the cooling mode, the gaseous refrigerant generated by the compressor 21 is condensed and releases heat through the condenser 22, and then becomes liquid refrigerant after being throttled by the throttle valve 23. Then, it flows into the evaporator 30 through the transfer tube 13 and the second cavity 5 of the transmission tube 1 to absorb heat and evaporate. The evaporated gaseous refrigerant flows back to the compressor 21 through the transfer tube 13 and the first cavity 4 of the transmission tube 1.

[0075] In heating mode, the gaseous refrigerant generated by the compressor 21 flows into the evaporator 30 through the transfer tube 13 and the first cavity 4 of the transmission pipe 1 to condense and release heat. The condensed liquid refrigerant flows into the throttle valve 23 through the transfer tube 13 and the second cavity 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.

[0076] (2) Signal transmission: The first controller 16 controls the switch circuit 17 and the signal modulation circuit 18 to send the power signal and the carrier communication signal to the first conductive component 2 and the second conductive component 3 respectively; then the power signal and the carrier communication signal are received by the signal isolation module 26, and the power signal and the carrier communication signal are isolated and separated, so that the power signal enters the power supply circuit 28, and the carrier communication signal enters the signal analysis circuit 27. The power supply circuit 28 outputs a specified voltage value signal to the second controller 29, and the carrier communication signal is transmitted to the second controller 29 after analysis, thereby realizing communication between the indoor unit and the outdoor unit.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them.
