In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0051] Combine the following Figure 1-Figure 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 Figure 1-Figure 4 As shown, the transmission pipe assembly for the 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. Among them, the transmission pipe 1 is a hollow structure; the first conductive component 2 and the second conductive component 3 have opposite conductive polarities, so as to form an electrical circuit for transmitting power signals and carrier communication signals. For example, the conductive polarity of the first conductive component 2 is positive, and the conductive polarity of the second conductive component 3 is negative.

[0053] 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 a first cavity 4, a second cavity 5 and an 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.

[0054] For example, Figure 1 As shown, the first conductive component 2 and the second conductive component 3 are horizontally arranged 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, and 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 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.

[0056] Therefore, the transmission pipe assembly for the air-conditioning system provided in the embodiment of the present invention can realize the simultaneous transmission of refrigerant, power supply signals and communication signals without affecting each other. It has at least three functions and realizes 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 risks of installation implementation.

[0057] According to one embodiment of the present invention, referring to Figure 2 As shown, first insulating components 7 are respectively provided between the first conductive component 2 and the tube wall of the transmission tube 1 on both 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 both sides along the radial direction of the transmission tube 1 .

[0058] Since the refrigerant transmission pipe of the air conditioning system is generally a metal pipe, such as a copper pipe, which is easy to conduct electricity, the embodiment of the present invention can effectively isolate the electrical connection between the conductive component and the transmission pipe 1 by respectively providing insulating components on both sides of the conductive component, thereby achieving an insulating effect and 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 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.

[0060] 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.

[0061] Similarly, the signal receiving line of the indoor control unit 25 of the indoor unit can extend into the first wire passing channel 9 and the second wire passing channel 10 respectively through the first wire passing hole 11 and the second wire passing 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 supply signals and carrier communication signals.

[0062] It is worth mentioning that when wiring, if the signal sending line and the signal receiving line are respectively connected to the first conductive component 2 and the second conductive component 3 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 the refrigerant, resulting in poor heat exchange effect; if the signal sending line and the signal receiving line are respectively connected to the first conductive component 2 and the second conductive component 3 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.

[0063] Therefore, the embodiment of the present invention cleverly utilizes insulating components and routes the wiring inside the insulating components, which can ensure the sending and receiving of signals on the one hand, and on the other hand, avoid obstruction to 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.

[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 an integrally formed structure, which is convenient for production and processing.

[0065] According to one embodiment of the present invention, 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 to improve the refrigerant heat exchange effect while ensuring signal transmission.

[0066] 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.

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

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

[0069] 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 ends of the first cavity 4 and the second cavity 5 are connected to both ends of the evaporator 30 of the indoor unit.

[0070] According to an embodiment of the present invention, 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.

[0071] According to one embodiment of the present invention, referring to Figure 2-Figure 4 As shown, the cross-sectional shape of the first end of the transfer tube 13 is arched, and correspondingly, the cross-sectional shape of the first cavity 4 and the second cavity 5 is arched, so as to realize the quick connection between the transmission tube 1 and the transfer tube 13; and, because the refrigerant pipeline of the air-conditioning system is generally a round tube and cannot be adjusted, the present invention designs the cross-sectional shape of the second end of the transfer tube 13 to be circular, so as to realize the quick connection between the transfer tube 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 an air conditioning system of the above embodiment, the outdoor unit and the indoor unit are cyclically connected through the transmission pipe assembly, thereby realizing refrigerant circulation transmission; and the outdoor unit is suitable for sending power signals and carrier communication signals to the first conductive component 2 and the second conductive component 3; the indoor unit is suitable for receiving power signals and carrier communication signals through the first conductive component 2 and the second conductive component 3, thereby realizing the transmission of power signals and carrier communication signals, and realizing communication between the indoor unit and the outdoor unit. It can 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 realizing signal transmission.

[0073] Therefore, the air-conditioning system provided in the embodiment of the present invention 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 risks of installation implementation.

[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 respectively via two communication signal lines for sending 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 provided in two communication signal lines. Such a design can isolate signal interference, thereby effectively improving communication quality.

[0077] 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 via the transfer tube 13, the throttle valve 23 is connected to the first end of the second cavity 5 of the transmission pipe 1 via 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, so as to adjust 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, and the indoor control unit 25 includes: a signal isolation module 26, a signal analysis circuit 27, a power supply circuit 28 and a second controller 29. Among them, the signal isolation module 26 can be connected to the first conductive component 2 and the second conductive component 3 respectively through two signal receiving lines, and is used to receive and isolate the power signal and the carrier communication signal, and isolate the power signal and the carrier communication signal; the signal analysis circuit 27 is connected to the signal isolation module 26, and is used to analyze 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 respectively connected to the signal analysis circuit 27 and the power supply circuit 28, and is used to receive the analyzed communication signal and voltage, so as to realize the simultaneous supply of power and communication.

[0079] 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 first cavity 4 and the second end of the second cavity 5 of the transmission tube 1 through the transfer tube 13.

The second controller 29 is connected to the indoor fan 31, and can control the rotation 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, which mainly includes: a refrigerant transmission process and a signal transmission process.

[0081] (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. It then 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.

[0082] In the 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 to be throttled, and then absorbs heat and evaporates in the condenser 22. The evaporated gaseous refrigerant flows back to the compressor 21.

[0083] (2) Signal transmission: The first controller 16 controls the switch circuit 17 and the signal modulation circuit 18 to send a power signal and a 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. The carrier communication signal is analyzed and transmitted to the second controller 29, thereby realizing 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, rather than to limit it.
