During start-up or normal operation, the pressure in the high-pressure pipeline may be too high, which may affect the normal operation of the compressor 1, and for this purpose, a part of the refrigerant discharged from the compressor 1 is discharged to the gas-liquid separator 2, so as to reduce the pressure in the high-pressure pipeline.

In the operation process of the air conditioner, the pressure of the pipeline connected with the inlet of the gas-liquid separator is lower than that of the pipeline connected with the outlet of the compressor, namely the pressure of the second pipeline is lower than that of the first pipeline, so that the refrigerant flows from the first pipeline to the second pipeline in a volume increasing process, namely the refrigerant has higher speed when flowing through the second pipeline, and the friction and impact of the high-speed refrigerant on the pipe wall of the second pipeline can generate larger noise. As shown in fig. 1 and 2, the second pipeline 5 includes a main pipeline 51 and a plurality of branches 52 extending from the main pipeline, and the refrigerant reaching the main pipeline 51 is divided by the plurality of branches 52, so that the flow rate of the refrigerant is dispersed, that is, the flow rate of the refrigerant passing through a single branch 52 is reduced, thereby effectively reducing the noise when the refrigerant flows through the second pipeline.
Referring to fig. 1, 2 and 3, fig. 3 is a schematic structural diagram of an outdoor unit of a multi-split air conditioner according to an embodiment of the present invention. As shown in fig. 1, fig. 2 and fig. 3, the outdoor unit of the present invention further includes a third pipeline 6 and a fourth pipeline 7, wherein the first end 61 of the third pipeline is connected to the gas-liquid separator 2, the second end 62 of the third pipeline is connected to the compressor 1, the first end 71 of the fourth pipeline is connected to the first pipeline 4, the second end 72 of the fourth pipeline is connected to the second pipeline 5, so that a part of the refrigerant coming out of the compressor 1 sequentially passes through the first pipeline 4 and enters the gas-liquid separator 2 after the valve, the other part enters the gas-liquid separator 2 through the fourth pipeline 7, and then the gaseous refrigerant having separated the liquid refrigerant comes out of the gas-liquid separator 2 and then enters the compressor 1 through the third pipeline for further compression.

For convenience of description, the following description will be made by taking a valve as an example of an electromagnetic valve and referring to the accompanying drawings.
With continued reference to fig. 2 and in the orientation shown in fig. 2, the solenoid valve 3 has an inlet section which is connected to the first conduit 4 and an outlet section which is connected to the second conduit 5. The second pipeline 5 includes a main pipeline 51 and a plurality of branches 52, the main pipeline 51 includes a connecting pipe section and a third pipe section 513 with one end closed, namely, the upper end of the connecting pipe section is connected with the outlet section, and the lower end of the connecting pipe section is connected with the communicating section of the third pipe section 513, so that when the solenoid valve is opened, the refrigerant flows from the first pipeline 4 to the connecting pipe section and further to the third pipe section 513.
With continued reference to fig. 1 and 2 and in the orientation shown in fig. 2, the connecting segments include a first segment 511 and a second segment 512, such that the upper end of the first segment 511 is connected to the outlet segment and the lower end of the first segment 511 is connected to the second segment 512, such that when the solenoid valve 3 is opened, refrigerant flows from the first conduit 4 to the first segment 511, the second segment 512 and the third segment 513 in sequence. The radial dimension of the second pipe section 512 is smaller than the radial dimension of the first pipe section 511 (for example, the outer diameter of the first pipe section is phi 6.35, and the outer diameter of the second pipe section is phi 4.76), and the flow rate of the refrigerant flowing through the second pipe section 512 is limited by the reduction of the radial dimension, so that the flow rate of the refrigerant flowing to the gas-liquid separator 2 through the first pipeline 4 and the second pipeline 5 is limited.
Preferably, the middle portion of the second pipe section is configured to be coiled (e.g., coiled in a clockwise direction by one turn) so as to extend the length of the second pipe section within a limited space range, that is, the length of the refrigerant flow limiting structure is extended, thereby better controlling the flow rate of the refrigerant flowing to the first pipeline and the second pipeline.
It should be noted that, during the operation of the air conditioner, the length of the second pipe section, that is, the number of turns of the middle part winding, may be set according to the specific application scenario, for example, in the situation that the pressure to be unloaded is less, the second pipe section needs to be wound more turns so as to extend the length of the second pipe section.
Through the arrangement mode, the radial size of the second pipe section is set to be smaller than that of the first pipe section so as to reduce the circulation path of the refrigerant, and the middle part of the second pipe section is set to be of a coiled structure so as to increase the length of the second pipe section, so that the flow rate of the refrigerant flowing to the gas-liquid separator through the first pipeline and the second pipeline can be better controlled, the pressure on the outlet pipeline of the compressor cannot be suddenly reduced greatly, and the running stability of the compressor is maintained.
It is understood that the radial dimension of the first pipe segment may be the same as the radial dimension of the second pipe segment, for example, the radial dimensions of the first pipe segment and the second pipe segment are smaller (for example, both are phi 4.76, etc.), and those skilled in the art can flexibly set the radial dimensions of the first pipe segment and the second pipe segment according to specific application scenarios as long as the first pipe segment and the second pipe segment can play a role of limiting the refrigerant flow.
With continued reference to fig. 2, a connecting pipe segment 515 is disposed between the second pipe segment 512 and the third pipe segment 513, wherein the radial dimension of the connecting pipe segment 515 is greater than the radial dimension of the second pipe segment 512 and less than the radial dimension of the third pipe segment 513, such that the refrigerant from the second pipe segment 512 flows to the third pipe segment 513 at a relatively smooth speed through the connecting pipe segment 515.
It will be appreciated that the connection of the connector segments to the second and third segments may be a nested connection, if one end is embedded outside the second pipe section and the other end is embedded inside the second pipe section, the connection can be an abutting connection, for example, the radial dimension of the connecting pipe section at the abutting end is reduced or expanded appropriately (the radial dimension at the end close to the second pipe section is gradually reduced to be the same as the second pipe section, and the radial dimension at the end close to the third pipe section is gradually increased to be the same as the third pipe section), and for example, the radial dimension of the connecting pipe section is gradually increased, one end is the same as the second pipe section, and the other end is the same as the third pipe section.
With continued reference to fig. 2, the radial dimension of the third pipe section 513 is greater than the radial dimension of the connecting pipe section, that is, the radial dimension of the third pipe section 513 is greater than the radial dimensions of the first pipe section 511 and the second pipe section 512 (for example, the outer diameter of the third pipe section is phi 12.7, the outer diameter of the first pipe section is phi 6.35, and the outer diameter of the second pipe section is phi 4.76), because the pressure of the second pipeline 5 is lower than that of the first pipeline 4, under the condition that the refrigerant flow rate is constant, the refrigerant flows from the first pipeline to the second pipeline 5 in a volume increasing process, and the radial dimension of the third pipe section 513 is properly increased to reduce the refrigerant flow rate, thereby better reducing the noise when the refrigerant flows through the second pipeline 5. Also, since the plurality of branches 52 are provided on the third pipe section 513, it is also necessary to increase the radial size of the third pipe section 513 appropriately in order to provide sufficient refrigerant to the plurality of branches 52. In addition, since the second pipeline is only a bypass in the process of circulating the refrigerant in the air conditioner, the radial dimension of the second pipeline is relatively small, and the radial dimension of the third pipeline also needs to be increased properly for the realizability of the process, that is, for arranging a structure (such as a through hole and the like) connected with a plurality of branches on the third pipeline.
With continued reference to fig. 2 and according to the orientation shown in fig. 2, the second pipeline 5 includes a fourth pipeline section 514, three branches 52 are axially connected in parallel in the third pipeline section 513, and left ends of the three branches 52 are connected to a pipe body of the fourth pipeline section 514, so that a path of the refrigerant flowing from the third pipeline section 513 to the fourth pipeline section 514 can be greatly shortened, and the arrangement of the refrigerant pipeline in the outdoor unit is optimized.
Preferably, the radial dimensions of the three branches are the same (for example, all are phi 6.35), and through the arrangement, the refrigerant can flow from the third pipe section to each branch at the same speed, so that noise caused by speed difference due to uneven flow distribution is avoided, and the noise generated when the refrigerant flows is further reduced. In addition, a plurality of branches with the same radial dimension do not need to be replaced by grinding tools in the machining and manufacturing process and the connection process of the branches with the third pipe section, and the machining and manufacturing processes are greatly simplified.
Through foretell mode of setting, through with three tributary way along the axial parallel arrangement of third pipeline section make the refrigerant can be with the shortest route flow direction fourth pipeline to and set up the radial dimension of three tributary ways to the same, realized having optimized the pipeline setting, simplified processing, manufacturing procedure on the basis of the noise that produces when reducing the refrigerant and flowing through the second pipeline.
It can be understood that the number of the branch lines may be other numbers, and those skilled in the art may flexibly set the number of the branch lines according to a specific application scenario, as long as the refrigerant can be shunted to achieve the purpose of reducing noise.
It can be understood that the radial dimensions of the plurality of branches may also be different, for example, the outer diameters of two branches are set to be phi 6.35, the outer diameter of one branch is set to be phi 4.76, etc., and those skilled in the art can flexibly select the radial dimensions of the branches according to the specific application scenarios to achieve the goals of splitting the refrigerant, reducing noise, and achieving the process.
With continued reference to fig. 2 and 3 and in the orientation shown in fig. 2, the body of the fourth tube section is connected to the plurality of branches 52 from the right, the lower end of the fourth tube section 514 is connected to the second end 72 of the fourth tube, and is further connected to the inlet of the gas-liquid separator 2, and the radial dimension of the fourth tube section 514 is greater than the radial dimension of the plurality of branches 52, so as to be able to receive the refrigerant from the plurality of branches. Through the arrangement mode, part of the refrigerant from the compressor sequentially passes through the first pipeline, and the refrigerant from the outlet of the compressor sequentially passes through the first pipeline, the valve, the outlet section, the first pipe section, the second pipe section, the connecting pipe section, the third pipe section, the plurality of branches and the fourth pipe section and then enters the gas-liquid separator.
The radial dimensions of the pipe sections are only exemplary, and in the actual design process, the radial dimensions of the pipe sections can be flexibly selected according to factors such as the power of the outdoor unit, the type of the electromagnetic valve and the like, as long as the stable operation of the compressor can be ensured and the noise generated in the pressure relief process can be reduced.

Preferably, the radial dimension of the second pipe section of the main path is smaller than that of the first pipe section, and at least a part of the second pipe section forms a coiled structure, so that the flow rate of the refrigerant flowing to the first pipeline and the second pipeline can be limited, thereby facilitating the stability of the operation of the compressor; the plurality of branches are arranged in parallel along the axial direction of the third pipe section, and the radial sizes of the plurality of branches are the same, so that the noise of the refrigerant flowing through the second pipeline is further reduced.
