Description

Technical Field

[0001] The utility model relates to the technical field of gas-liquid separators, in particular to a gas-liquid separator with multiple gas outlet pipes. Background Art

[0002] The main function of the gas-liquid separator is to separate gas and liquid. The liquid refrigerant can remain in the gas-liquid separator, while the gaseous refrigerant is transported to the compressor for recirculation to prevent the compressor from suffering from liquid hammer due to excessive liquid return. It can also avoid excessive dilution of the lubricating oil, thereby affecting the lubrication effect of the compressor bearings. Therefore, the gas-liquid separator is crucial in the entire system.

[0003] Conventional gas-liquid separators currently installed on the air conditioner evaporator and compressor suction pipe usually have only one outlet and can only be connected to one conventional compressor. When there are three compressors or three-cylinder compressors in a multi-split air conditioning system, three gas-liquid separators must be installed accordingly, which results in a higher cost for the entire unit and makes the unit piping system more complicated, thereby increasing the processing cost.

[0036] The existing gas-liquid separator usually has only one gas outlet and can only be connected to one conventional compressor. When three compressors or a multi-cylinder compressor are provided in the system, only multiple gas-liquid separators can be provided, resulting in a high cost of the whole equipment and a more complicated unit piping system, which in turn increases the processing cost. In this application, three compressors or a three-cylinder compressor are used as an example for detailed description.

[0037] In view of this problem, the utility model provides a gas-liquid separator with multiple air outlet pipes, which can be applied to a three-cylinder compressor and a system pipeline with three single-port compressors.

[0038] See also Figure 1-Figure 2 The gas-liquid separator 100 with multiple air outlets includes a cylinder 10, an air inlet pipe 20 and an air outlet pipe group. The cylinder 10 is configured with a cavity 11. The air inlet pipe 20 is arranged at one end of the cylinder 10 and communicated with the cavity 11. The air outlet pipe group is arranged at the other end of the cylinder 10 and communicated with the cavity 11. The air outlet pipe group includes at least three air outlet pipes, and the three air outlet pipes are respectively communicated with the cavity. In this way, the medium can enter the cavity 11 through the air inlet pipe 20, and then flow out of the cylinder 10 through the three air outlet pipes. Since the air outlet pipe group includes three air outlet pipes, the air outlet pipe group can be directly connected to a three-cylinder compressor (a compressor requiring three inlets) or three single-port compressors, so there is no need to set three gas-liquid separators in the system, which simplifies the pipeline structure and reduces the cost of the whole machine.

[0039] Further, the three outlet pipes are respectively a first outlet pipe 30, a second outlet pipe 40 and a third outlet pipe 50. The first outlet pipe 30 includes a first inlet 31 and a first outlet 32, the second outlet pipe 40 includes a second inlet 41 and a second outlet 42, and the third outlet pipe 50 includes a third inlet 55 and a third outlet 51; the first inlet 31, the second inlet 41 and the third inlet 55 are all located in the cavity 11 and communicated with the cavity 11, and along a first direction parallel to the axis direction of the cylinder 10 and away from the air inlet pipe 20, the first outlet 32, the second outlet 42 and the third outlet 51 are arranged in sequence at intervals.

[0040] In this way, the first inlet 31, the second inlet 41 and the third inlet 55 are all located in the cavity 11 and connected with the cavity 11, ensuring that the medium can enter the first air outlet pipe 30, the second air outlet pipe 40 and the third air outlet pipe 50. Along the first direction, the first outlet 32, the second outlet 42 and the third outlet 51 are arranged in sequence at intervals, so that the three can independently connect to the inlets of three compressors, or independently connect to the three inlets on a compressor to avoid mutual influence.

[0041] See also Figure 1 , it needs to be explained that the first direction refers to Figure 1The direction from top to bottom and parallel to the axis.

[0042] Of course, in other embodiments, the first outlet 32, the second outlet 42 and the third outlet 51 may also be arranged in parallel horizontally (in a direction perpendicular to the first direction), or in a triangular arrangement, etc., as long as they can adapt to the compressor inlet connected to the gas-liquid separator, and are not limited to a single arrangement of the first outlet 32, the second outlet 42 and the third outlet 51.

[0043] Furthermore, the first outlet 32, the second outlet 42 and the third outlet 51 are all circular, and the centers of the first outlet 32, the second outlet 42 and the third outlet 51 are located on the same straight line parallel to the first direction. In this way, the processing consistency of the three is better, and the compatibility with the three-cylinder compressor is higher, which solves the problem that the suction flow difference of the three cylinders of the three-cylinder compressor affects the compressor performance, has a good air return effect, reduces the cost of the whole equipment, optimizes the design of the unit pipeline, and reduces the processing cost.

[0044] Of course, in other embodiments, the first outlet 32, the second outlet 42 and the third outlet 51 may also be configured as a triangle or a square, and are not limited to the above-mentioned circle.

[0045] Specifically, the first air outlet pipe 30 includes a first air inlet section 33, a first bending section 34 and a first air outlet section 35. At least a portion of the first air inlet section 33 is located in the cavity 11. The first inlet 31 is opened in the portion of the first air inlet section 33 located in the cavity 11. The first bending section 34 is connected to the first air inlet section 33 and is bent in the radial direction of the cylinder 10. The first air outlet section 35 is connected to an end of the first bending section 34 away from the first air inlet section 33 and is connected along the first bending section 34. 4, and the first outlet 32 ​​is opened at one end of the first outlet section 35 away from the first bending section 34, and the bending direction of the first bending section 34 is defined as the second direction; the second outlet pipe 40 includes a second inlet section 43, a second bending section 44 and a second outlet section 45, at least part of the second inlet section 43 is located in the cavity 11, the second inlet 41 is opened at the part of the second inlet section 43 located in the cavity 11, and the second bending section 44 is connected to the second inlet section 43. And extends toward the second direction, the second air outlet section 45 is connected to the end of the second bending section 44 away from the second air inlet section 43, and extends along the second direction, the second outlet 42 is opened at the end of the second air outlet section 45 away from the second bending section 44; the third air outlet pipe 50 includes a third air inlet section 52, a third bending section 53 and a third air outlet section 54, at least part of the third air inlet section 52 is located in the cavity 11, the third inlet 55 is opened at the part of the third air inlet section 52 located in the cavity 11, the third bending section 53 is connected to the third air inlet section 52 and extends toward the second direction, the third air outlet section 54 is connected to the end of the third bending section 53 away from the third air inlet section 52, and extends along the second direction, the third outlet 51 is opened at the end of the third air outlet section 54 away from the third bending section 53; wherein, along the first direction, the second outlet 42 is located on the side of the first outlet 32 ​​away from the cylinder 10, and the third outlet 51 is located on the side of the second outlet 42 away from the cylinder 10.

[0046] In this way, the first air inlet section 33, the second air inlet section 43 and the third air inlet section 52 are located in the cylinder 10, and are dedicated to supplying medium to enter. The first bending section 34 is connected to the first air inlet section 33, and is located outside the cylinder 10. After bending, it extends in the second direction, that is, the flow direction of the medium is changed. The first air outlet section 35 is connected to the first bending section 34, and the first air outlet section 35 allows the medium to flow out and is connected to the compressor. Through the cooperation of the first air inlet section 33, the first bending section 34 and the first air outlet section 35, the first air outlet pipe 30 guides and turns the medium in the cylinder 10 and passes it into the compressor. The second bending section 44, the third bending section 53, the second air outlet section 45 and the third air outlet section 54 (that is, the second air outlet pipe 40 and the third air outlet pipe 50) are also the same, which will not be repeated here.

[0047] The plane constructed by the first direction and the second direction is the first plane, the axes of the first air inlet section 33, the first bending section 34, the first air outlet section 35, the second air outlet section 45 and the third air outlet section 54 are all located on the first plane, the second bending section 44 and the third bending section 53 are all inclined toward the direction where the first plane is located and extend to the first plane; the end of the first air outlet section 35 with the first outlet 32, the end of the second air outlet section 45 with the second outlet 42 and the end of the third air outlet section 54 with the third outlet 51 are arranged flush in the second direction. In this way, the second bending section 44 and the third bending section 53 are all extended toward the first plane, so that the second outlet 42 and the third outlet 51 can be located together with the first outlet 32 ​​in the first direction. Furthermore, since these outlets are aligned in the second direction, the midpoints of the first outlet 32, the second outlet 42 and the third outlet 51 are located on the same straight line, and the straight line is also parallel to the first direction, thereby making the arrangement of the first outlet 32, the second outlet 42 and the third outlet 51 more regular to improve their adaptability to the compressor.

[0048] See also Figure 1 , in the first direction, the first air inlet section 33 is located in the cylinder 10, the length of the portion of the second air inlet section 43 extending out of the cylinder 10 is C2, the length of the portion of the third air inlet section 52 extending out of the cylinder 10 is C1, the lengths of the first bending section 34, the second bending section 44 and the third bending section 53 are B3, B2 and B1 respectively; in the second direction, the lengths of the first air outlet section 35, the second air outlet section 45 and the third air outlet section 54 are A3, A2 and A1 respectively; satisfying: -0.1 ≤[(A1+B1+C1)-(A2+B2+C2)] / [(A1+B1+C1)+(A2+B2+C2)]≤0.1; and / or, -0.1≤[(A2+B2+C2)-(A3+B3+C3)] / [(A2+B2+C2)+(A3+B3+C3)]≤0.1; and / or, -0.2≤[(A1+B1+C1)-(A3+B3+C3)] / [(A1+B1+C1)+(A3+B3+C3)]≤0.2. In this way, the length relationship between the first outlet pipe 30, the second outlet pipe 40 and the third outlet pipe 50 is reasonably specified to prevent the large size difference between the three from causing a large flow difference of the gas medium and affecting the performance of the compressor.

[0049] See also Figure 4In this embodiment, the first air inlet section 33, the second air inlet section 43 and the third air inlet section 52 are arranged at intervals from each other in a triangular layout, and the axes of the first air inlet section 33, the second air inlet section 43 and the third air inlet section 52 are parallel to the first direction. The triangular arrangement allows the first air outlet pipe 30, the second air outlet pipe 40 and the third air outlet pipe 50 to be arranged at equal distances from each other, and the three are arranged evenly in an array, thereby ensuring more uniform air outlet.

[0050] In another embodiment, the first air intake section 33 , the second air intake section 43 and the third air intake section 52 may also be arranged in a straight line in the second direction.

[0051] See also Figure 3 When the gas-liquid separator 100 with multiple outlet pipes is applied to a compressor, the diameters of the first outlet pipe 30 , the second outlet pipe 40 , and the third outlet pipe 50 can be flexibly adjusted according to compressors of different capacities to adapt to compressors of different capacities.

[0052] In this embodiment, when the first air inlet section 33, the second air inlet section 43 and the third air inlet section 52 are arranged in a triangle arrangement with intervals from each other, the bending direction of the first bending section 34 is the front side, and the opposite direction is the rear side, and the second air inlet section 43 and the third air inlet section 52 are both located at the rear side of the first air inlet section 33. In this way, the first air outlet pipe 30, the second air outlet pipe 40 and the third air outlet pipe 50 can form an avoidance space between each other, so that the first outlet 32, the second outlet 42 and the third outlet 51 are arranged in a straight line and in parallel.

[0053] On this basis, preferably, the flow area of ​​the second outlet 42 is larger than the flow area of ​​the first outlet 32, and the flow area of ​​the third outlet 51 is larger than the flow area of ​​the second outlet 42. In this way, since the pressure difference caused by the pipe length (including three outlet pipes) generates resistance to the flow of the refrigerant, the refrigerant flow rate at the output port is inconsistent, so such a setting can increase the flow rate of the second outlet pipe 40 and the flow rate of the third outlet pipe 50, so that although the lengths of the first outlet pipe 30, the second outlet pipe 40 and the third outlet pipe 50 gradually increase, the output flow rate remains consistent.

[0054] In addition, the gas-liquid separator 100 with multiple air outlets also includes a mounting plate 60 and a filter screen 70. The mounting plate 60 is disposed in the cylinder 10, and the outer peripheral side of the mounting plate 60 is connected to the inner wall of the cylinder 10. Three mounting holes are opened on the mounting plate 60, and each air outlet pipe is respectively passed through a mounting hole. The filter screen 70 is installed in the cylinder 10 and is located between the air inlet pipe 20 and the air outlet pipe.

[0055] The mounting plate 60 can align the first air outlet pipe 30 , the second air outlet pipe 40 and the third air outlet pipe 50 through three mounting holes, so that the positions between the three are more stable, avoiding shaking, and improving the working stability of the gas-liquid separator.

[0056] The filter screen 70 is located between the air inlet pipe 20 and the air outlet pipe group. After the medium enters the cylinder 10 from the air inlet pipe 20, it will be filtered by the filter screen 70 to ensure that no impurities enter the air outlet pipe group, that is, no impurities enter the compressor.

[0057] Compared with the prior art, the utility model is provided with three air outlet pipes, and the medium can enter the cavity 11 through the air inlet pipe 20, and then flow out of the cylinder 10 through the three air outlet pipes. Since the air outlet pipe group includes three air outlet pipes, the air outlet pipe group can be directly connected to a three-cylinder compressor (a compressor requiring three inlets) or three single-port compressors, so there is no need to set up three gas-liquid separators in the system, which simplifies the pipeline and reduces the cost of the whole machine.

[0058] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
