Description

Technical Field

[0001] This application relates to the field of separators, and particularly to a gas-liquid separation partition, a liquid distributor, and an air conditioner. Background Art

[0002] In fluid processing equipment, the gas-liquid separation partition of the liquid distributor plays a crucial role, and its performance directly affects the working efficiency and stability of the equipment. Currently, in the liquid receiver for a compressor and related compressor technologies, the partition assembly of the liquid receiver usually consists of a cylinder body and a partition. The cylinder body is connected to the inner peripheral wall of the main body, and the partition is arranged inside the cylinder body. Although this structure can effectively improve the stiffness of the liquid receiver, increase the natural frequency, and reduce vibration and noise, it has poor performance in gas-liquid separation and cannot meet the requirements of efficient gas-liquid separation.

[0003] In addition, for some existing partitions, liquid distributors, and compressor products, the partition structure adopted includes a driving member and an opening conversion member. This design makes the overall structure complex to implement, not only increasing the assembly difficulty but also significantly raising the production cost, which is not conducive to the large-scale popularization and application of the products. There is also a liquid distributor partition applied to an air-conditioning compressor. A spherical baffle integrally connected to the partition body is covered on the gas-liquid separation hole, and gas-liquid separation is achieved by relying on the spherical baffle to block the liquid in the gas-liquid mixture. However, the processing of this spherical baffle has strict requirements for material properties, complex processing technology, and great processing difficulty, further pushing up the product cost and limiting its competitiveness in the market. In summary, the existing gas-liquid separation partitions of liquid distributors have problems to varying degrees in terms of gas-liquid separation efficiency, structural complexity, production cost, and processing difficulty. There is an urgent need to propose a new technical solution for gas-liquid separation partitions to solve the above technical problems. Summary of the Invention

[0033] During the operation of the compressor, there will be a certain amount of liquid refrigerant in the liquid separator. When the gaseous refrigerant enters the compressor, it will carry some liquid refrigerant. To ensure the energy efficiency of the compressor, the liquid carry-over in the exhaust of the liquid separator should be minimized.

[0034] However, the existing liquid separators still have a relatively large amount of liquid carry-over in the exhaust. To alleviate this problem, the gas-liquid separation partition provided in the embodiments of the present application increases the gas-liquid separation path, can further separate the gas and liquid, reduce the liquid refrigerant from entering the straight pipe, reduce the liquid carry-over in the exhaust of the liquid separator, improve the gas-liquid separation rate and the stiffness of the liquid separator, reduce noise and vibration, and improve and more effectively ensure the energy efficiency of the compressor.

[0035] Specifically, referring to Figures 1 - 9 , the embodiments of the present application provide a gas-liquid separation partition applied to a liquid separator, including: a first partition 1, a second partition 2 located below the first partition 1, and a cylinder 3 connected between the first partition 1 and the second partition 2. An integral structure is formed among the first partition 1, the cylinder 3, and the second partition 2; a one-way channel for fluid flow is reserved between the outer walls of the first partition 1, the second partition 2, and the cylinder 3; the first partition 1 has a first through-hole 11, and the first through-hole 11 is configured to communicate with the one-way channel or the inner cavity of the cylinder 3, so that the gas-liquid mixed fluid in the upper space of the first partition 1 flows to the one-way channel or the inner cavity of the cylinder 3; the cylinder 3 has a third through-hole 31, and the third through-hole 31 is configured to communicate the one-way channel with the inner cavity of the cylinder 3, so that the gas-liquid mixed fluid or the gaseous fluid can flow between the two; the second partition 2 has a second through-hole 21, and the second through-hole 21 is configured to communicate with the one-way channel or the inner cavity of the cylinder 3, so that the liquid fluid deposited in the upper space of the second partition 2 flows out, or the gaseous fluid in the upper space of the second partition 2 flows out.

[0036] Exemplarily, the integral structure formed among the first partition 1, the cylinder 3, and the second partition 2 can be an integrally synthesized overall structure formed by injection molding or other processing techniques, without the need for other structural components for connection; it forms an integral three-dimensional support frame, which has stronger anti-deformation ability compared to the split structure.

[0037] Exemplarily, the integral structure formed among the first partition 1, the cylinder 3, and the second partition 2 can also be an integral structure formed by combining and connecting with connectors, and such a structure is easier to disassemble or maintain.

[0038] Among them, the gas-liquid separation partition plate has a simple structure. Under the structural arrangement of the gas-liquid separation partition plate with an integrated structure, through the settings of the first flow-through hole 11, the second flow-through hole 21, and the third flow-through hole 31, the gas-liquid mixed fluid flowing in from above the first partition plate 1 can form multiple gas-liquid separation paths between the first partition plate 1, the one-way channel, inside the cylinder body 3, and the second partition plate 2 during the process of flowing through the gas-liquid separation partition plate, achieving an efficient gas-liquid separation effect.

[0039] The gas-liquid separation partition plate provided by the embodiment of the present application designs the gas-liquid separation partition plate as an integrated structure and scientifically arranges the first flow-through hole 11, the second flow-through hole 21, and the third flow-through hole 31, realizing a comprehensive improvement in gas-liquid separation performance and the overall performance of the product: the integrated structure avoids the assembly gap and stress concentration problems caused by connecting parts in the traditional split partition plate, improves the stiffness of the partition plate, effectively suppresses the vibration and noise generated by air flow impact, and reduces the operating noise.

[0040] Considering the first gas-liquid separation path solution, in the solution of the gas-liquid separation partition plate provided by the embodiment of the present application, the first flow-through hole 11 is used to connect the upper space of the first partition plate 1 and the one-way channel; the second flow-through hole 21 is used to connect the one-way channel and the lower space of the second partition plate 2; the third flow-through hole 31 is used to connect the one-way channel and the inner cavity of the cylinder body 3; the gas-liquid mixed fluid is configured to flow through the first flow-through hole 11 to the one-way channel, liquid deposition occurs in the one-way channel, the liquid fluid flows out through the second flow-through hole 21, and the gaseous fluid flows through the third flow-through hole 31 to the inner cavity of the cylinder body 3 and flows out from the inner cavity of the cylinder body 3.

[0041] In this way, after the gas-liquid mixed fluid enters through the first flow-through hole 11, due to the expansion of the channel cross-sectional area, the flow velocity drops suddenly, and the liquid refrigerant quickly settles to the bottom of the channel under the action of gravity to form a stable liquid layer; the remaining liquid droplets are further trapped due to inertia hitting the channel wall surface, realizing an improvement in the primary separation efficiency; the second flow-through hole 21 directionally drains the liquid refrigerant at the bottom of the channel, avoiding the backmixing of the liquid layer with the air flow disturbance, and ensuring that the liquid "only goes out and does not come in"; the third flow-through hole 31 only allows gaseous fluid (and extremely fine liquid droplets) to enter the inner cavity of the cylinder body 3. Through "forced gas-liquid shunt", the liquid-carrying amount entering the subsequent flow channel is compressed, laying a foundation for the low liquid-carrying amount of the final exhaust.

[0042] Considering the position solution of the first flow-through hole 11 in the first gas-liquid separation path solution, in the gas-liquid separation partition plate provided by the embodiment of the present application, the first flow-through hole 11 is located in the outer peripheral region of the first partition plate 1, and the first flow-through hole 11 is located outside the cylinder body 3.

[0043] In this way, by utilizing the long-path sedimentation effect, when the gas-liquid mixed fluid cuts into the one-way channel from the outer peripheral area of the first partition plate 1, due to inertia lag and gravity traction of the liquid refrigerant, it is more likely to deposit towards the bottom of the channel, improving the initial separation droplet capture rate and reducing the liquid carry-over in the subsequent flow channels from the source; it can suppress turbulence, reduce the flow pressure drop, decrease the system energy consumption, and improve the compressor suction efficiency; it disperses the load of the first partition plate 1, and together with the annular support frame, improves the structural anti-deformation ability and service life; it realizes the spatial partition of "outer peripheral liquid path + central gas path", eliminates the secondary mixing of gas and liquid, reduces the liquid carry-over in the exhaust of the liquid-gas separator and increases the gas-liquid separation rate; the large-capacity deposition space in the outer peripheral channel enhances the adaptability to variable working conditions such as high liquid content, reduces the fluctuation of the separation efficiency under variable working conditions, and ensures the stable operation of the compressor under all working conditions. Through the triple optimization of the flow path, structure, and function, it breaks through the bottleneck of the traditional liquid-gas separator and provides a solution with high efficiency, low resistance, and long life.

[0044] Considering the position scheme of the second through-flow hole 21 in the first gas-liquid separation path solution, in the gas-liquid separation partition plate provided by the embodiment of the present application, the second through-flow hole 21 is located in the area close to the outer periphery of the second partition plate 2, and the second through-flow hole 21 is located outside the cylinder body 3.

[0045] In this way, due to the outer peripheral layout of the second through-flow hole 21, the liquid refrigerant deposited in the one-way channel can more smoothly drain from the outer peripheral position close to the bottom of the channel by means of gravity and fluid flow inertia, reducing the retention and accumulation of the liquid refrigerant in the one-way channel, avoiding secondary entrainment caused by excessive liquid accumulation, and improving the thoroughness of liquid drainage in a single separation; in addition, this position echoes the outer peripheral layout of the first through-flow hole 11, making the flow path of gas and liquid in the one-way channel more regular, promoting gas-liquid stratification, and using the relatively stable flow field environment in the outer peripheral area to reduce the airflow interference during liquid drainage, ensuring the continuity and stability of gas-liquid separation; it can effectively drain the liquid, ensure that the liquid-gas separator maintains a high-efficiency separation state, reduce the liquid refrigerant brought into the compressor suction end, improve the operation energy efficiency of the compressor, and at the same time alleviate the vibration and noise problems caused by liquid accumulation, enhancing the adaptability and reliability of the liquid-gas separator and the compressor system. Through the precise arrangement of the liquid drainage channel in the outer periphery, the collaborative optimization of gas-liquid separation efficiency, system stability, and energy efficiency is realized.

[0046] Considering the position scheme of the third through-flow hole 31 in the first gas-liquid separation path solution, in the gas-liquid separation partition plate provided by the embodiment of the present application, the third through-flow hole 31 is located in the lower area of the side wall of the cylinder body 3.

[0047] In this way, setting the third flow hole 31 in the lower area of the side wall of the cylinder 3 can make full use of the property that the liquid refrigerant in the gas-liquid mixed fluid is easy to deposit at the bottom due to its high density, so that the gaseous fluid after gas-liquid separation in the one-way channel can more efficiently enter the inner cavity of the cylinder 3 from the one-way channel when flowing through this position, thereby reducing the entrainment of residual liquid refrigerant in the gaseous fluid; at the same time, the layout of the lower area conforms to the gas-liquid stratification law under the action of gravity. When the gaseous fluid flows upward through the third flow hole 31, the liquid refrigerant is more likely to remain at the bottom of the one-way channel due to gravity and be discharged through the second flow hole 21, thereby enhancing the gas-liquid separation effect, reducing the amount of liquid carried in the exhaust gas of the separator, and improving the gas-liquid separation rate, thereby ensuring the energy efficiency of the compressor.

[0048] Considering the outflow scheme of the gaseous fluid in the cylinder 3 in the first gas-liquid separation path scheme, in the gas-liquid separation partition provided in the embodiment of the present application, the gas-liquid separation partition also includes a first tube 6, and the first tube 6 is inserted into the cylinder 3 through the second partition 2 so that the space below the second partition 2 is connected to the inner cavity of the cylinder 3 through the first tube 6.

[0049] In this way, by adding the first tube 6 and inserting it into the cylinder 3 through the second partition 2, the space below the second partition 2 is connected with the inner cavity of the cylinder 3 to form a directional exhaust channel, which can provide an exclusive and stable outflow path for the gaseous fluid separated in the cylinder 3. Compared with the non-directional structure, it reduces the disordered diffusion and energy loss of the airflow in the separator, allows the gaseous fluid to flow out with lower resistance and more uniform flow rate, and reduces the system pressure drop.

[0050] Exemplarily, the first tube 6 adopts a straight tube structure, that is, it achieves the effect of vertical insertion, and cooperates with the overall structure of the gas-liquid separation partition, using the principles of gravity and fluid mechanics to further enhance the gas-liquid separation effect. The residual liquid refrigerant is more likely to slide along the tube wall to the bottom of the second partition 2 due to gravity and be discharged, effectively avoiding secondary mixing of the liquid refrigerant.

[0051] Considering the first gas-liquid separation path, the first tube 6 can be used to ensure the smooth outflow of the gaseous fluid. In the gas-liquid separation partition provided in the embodiment of the present application, one end of the first tube 6 that is used to extend into the interior of the cylinder 3 is located in the upper area of the cylinder 3.

[0052] In this way, the end of the first tube 6 extending into the interior of the cylinder 3 is set in the upper area of the cylinder 3, which can form an efficient gaseous fluid extraction path; due to the effect of gravity, the liquid refrigerant is mostly deposited in the lower part of the cylinder 3, and the purity of the gaseous fluid in the upper area is higher. The end of the first tube 6 is located in this area, which can preferentially extract pure gaseous refrigerant, greatly reducing the amount of liquid in the exhaust gas. Compared with the traditional random extraction method, the gas-liquid separation efficiency can be improved; this layout shortens the rising path of the gaseous fluid in the cylinder 3, reduces the flow resistance, makes the fluid flow smoother, reduces the system pressure drop, and improves the suction efficiency of the compressor.

[0053] Considering the solution of the second gas-liquid separation path, in the gas-liquid separation baffle provided in the embodiment of the present application, the first through-hole 11 is used to connect the upper space of the first baffle 1 and the inner cavity of the cylinder body 3; the second through-hole 21 is used to connect the inner cavity of the cylinder body 3 and the lower space of the second baffle 2; the third through-hole 31 is used to connect the inner cavity of the cylinder body 3 and the one-way channel; the gas-liquid mixed fluid is configured to flow to the inner cavity of the cylinder body 3 through the first through-hole 11, and perform a primary liquid deposition in the inner cavity of the cylinder body 3. The gas-liquid mixed fluid flows to the one-way channel through the third through-hole 31 and performs a secondary liquid deposition in the one-way channel. Then, the gaseous fluid flows out through the second through-hole 21.

[0054] In this way, an efficient separation mechanism of "two-stage gradient separation + three-dimensional space utilization" is constructed, significantly improving the gas-liquid separation performance and system stability; through two-stage deposition, the separation efficiency is broken through: the gas-liquid mixed fluid directly enters the inner cavity of the cylinder body 3 through the first through-hole 11, and the first gravity separation is formed by using the vertical space of the cylinder body 3. Larger particle-size liquid refrigerant quickly settles to the inner wall of the cylinder body 3 due to gravity and slides to the upper part of the second baffle 2; the remaining gas-liquid mixed fluid laterally cuts into the one-way channel through the third through-hole 31. Due to the sudden expansion of the channel cross-sectional area and the change of the flow direction, a secondary inertial separation is triggered. Tiny liquid droplets complete the secondary deposition under the action of wall collision and sudden drop of the flow velocity. The two-stage separation improves the total separation efficiency, and the liquid carry-over in the exhaust can be significantly reduced; furthermore, the flow pattern is optimized and the energy consumption is significantly reduced: this path design makes the fluid flow in a vertical laminar flow in the inner cavity of the cylinder body 3 and in a horizontal slow flow in the one-way channel, effectively suppressing the generation of turbulence, reducing the overall pressure drop of the system, reducing the suction resistance of the compressor, improving the volumetric efficiency, and improving the energy efficiency ratio of the system; at the same time, the stable flow pattern reduces the fluid impact noise, and the noise value is lower than that of the traditional liquid distributor; combined with the integrated molding process, the structural anti-deformation ability is improved; the two-stage separation path reduces the load pressure of a single flow channel, avoids structural fatigue caused by local liquid accumulation, extends the service life, and ensures the long-term stable operation of the system.

[0055] Considering the position solution of the first through-hole 11 in the solution of the second gas-liquid separation path, in the gas-liquid separation baffle provided in the embodiment of the present application, the first through-hole 11 is located in the middle area of the first baffle 1, and the first through-hole 11 is located within the barrel opening area of the cylinder body 3.

[0056] In this way, it can be ensured that in the solution of the second gas-liquid separation path, the upper space of the first baffle 1 is connected to the inner cavity of the cylinder body 3 through the first through-hole 11.

[0057] In the solution considering the second gas-liquid separation path, regarding the scheme of how to achieve the communication between the first partition 1 and the inner cavity of the cylinder 3 through the first flow hole 11, in the gas-liquid separation partition provided by the embodiment of the present application, the gas-liquid separation partition further includes a second pipe 13. The second pipe 13 is inserted into the cylinder 3 through the first flow hole 11, so that the space above the first partition 1 is communicated with the inner cavity of the cylinder 3 through the second pipe 13.

[0058] In this way, by adding the second pipe 13 and inserting it into the inner cavity of the cylinder 3 through the first flow hole 11, a specific diversion channel is obtained, which can accurately control the flow direction of the gas-liquid mixed fluid, avoid the turbulence generated by the impact, improve the primary separation efficiency of the liquid refrigerant, and reduce the subsequent separation load. At the same time, the second pipe 13 and the partition plate and the cylinder 3 form a nested support structure, enhancing the overall stiffness, improving the anti-deformation ability, and reducing the vibration noise. In addition, the stable diversion reduces the flow resistance, reduces the compressor suction energy consumption, improves the energy efficiency ratio, ensures the stable gas-liquid separation efficiency, and comprehensively improves the performance of the liquid distributor and the reliability of the system operation.

[0059] Considering the position scheme of the second pipe 13 can smoothly facilitate the liquid deposition of the gas-liquid mixed fluid in the cylinder 3. In the gas-liquid separation partition provided by the embodiment of the present application, the end of the second pipe 13 extending into the cylinder 3 is located in the lower region of the cylinder 3.

[0060] In this way, after the gas-liquid mixed fluid enters the cylinder 3, it quickly contacts the bottom of the cylinder 3 under the action of gravity. The liquid refrigerant can start to settle at a lower height, greatly shortening the liquid deposition path, improving the deposition efficiency, and effectively reducing the probability of the liquid refrigerant entering the one-way channel with the gaseous fluid. Secondly, the diversion design in the lower region cooperates with the structure of the cylinder 3 to guide the gas-liquid mixed fluid to form a spiral upward flow state. The liquid refrigerant is accelerated and separated under the dual action of centrifugal force and gravity, further strengthening the primary separation effect, and the gas-liquid separation rate can be further improved. Moreover, the low-position access mode of the second pipe 13 reduces the risk of the fluid impacting the top of the cylinder 3, reduces the vibration and noise generated by the impact, reduces the vibration amplitude, and reduces the operating noise. In addition, it can also enable the gas-liquid separation partition to maintain stable performance under high liquid content conditions. The rapid deposition of the liquid refrigerant avoids excessive liquid accumulation inside the cylinder 3, ensuring the reliability of the system operation under all working conditions.

[0061] Considering the position scheme of the second flow hole 21 in the solution of the second gas-liquid separation path, in the gas-liquid separation partition provided by the embodiment of the present application, the second flow hole 21 is located in the middle region of the second partition 2, and the second flow hole 21 is located in the bottom region of the cylinder 3.

[0062] In this way, it can be ensured that in the second gas flow separation path, the second flow hole 21 can communicate between the cylinder 3 and the lower space of the second partition 2.

[0063] Considering the solution for how to achieve the connection between the one-way channel and the space below the second partition 2 through the second flow hole 21 in the solution of the second gas-liquid separation path, in the gas-liquid separation partition provided by the embodiment of the present application, the gas-liquid separation partition further includes a third pipe 23, and the third pipe 23 is inserted between the one-way channel and the second partition 2 through the second flow hole 21, so that the space below the second partition 2 is communicated with the one-way channel through the third pipe 23.

[0064] In this way, by adding the third pipe 23 and connecting the one-way channel and the space below the second partition 2 through the second flow hole 21, an efficient diversion channel is constructed. The third pipe 23 forms a specific export path for gaseous fluid, avoiding the disordered flow of fluid in the liquid separator, reducing the risk of secondary entrainment of liquid refrigerant caused by air flow disturbance, and reducing the liquid carry-over in exhaust gas; at the same time, the fluid flow path is optimized, the flow resistance is reduced, the system pressure drop is reduced, the suction efficiency of the compressor is improved, and thus the system energy efficiency ratio is increased; furthermore, the combined structure of the third pipe 23 with the partition and the channel enhances the overall stiffness of the gas-liquid separation partition, reduces the vibration generated by air flow impact, and the design of the third pipe 23 is adapted to different specifications of liquid separators, and can ensure stable gas-liquid separation efficiency and improve the operation reliability of the equipment under various working conditions such as heat pumps and refrigeration.

[0065] Considering the position solution of the third pipe 23 can smoothly facilitate the deposition of the gas-liquid mixed fluid in the one-way channel. After that, the gaseous fluid can flow from the upper space to the space below the second partition 2 through the third pipe 23. In the gas-liquid separation partition provided by the embodiment of the present application, the end of the third pipe 23 extending into the one-way channel is located in the upper region of the one-way channel.

[0066] In this way, the pure gaseous fluid after deposition in the one-way channel can be quickly exported through the third pipe 23 located in the upper region with the least interference, effectively avoiding stirring the liquid refrigerant deposited at the bottom of the channel when extracting the gaseous fluid, reducing the risk of secondary entrainment, and further reducing the liquid carry-over in exhaust gas; at the same time, the export path in the upper region shortens the flow distance of the gaseous fluid, reduces the flow resistance, reduces the system pressure drop, and improves the suction efficiency of the compressor.

[0067] Considering the formation solution of the one-way channel, the radial dimensions of the first partition 1 and the second partition 2 are greater than the radial dimension of the cylinder 3.

[0068] In this way, the formation of the one-way channel can be ensured, and a specific gas-liquid separation path can be obtained.

[0069] Further considering the formation scheme of the one-way channel, a partition plate 4 is provided between the outer wall of the cylinder body 3, the first partition plate 1 and the second partition plate 2, so as to form the one-way channel between the gas-liquid separation partition plate and the inner wall of the liquid distributor.

[0070] In this way, under the setting of the partition plate 4, the problem of disordered flow of the fluid in the channel where the outer wall of the cylinder body 3 is located can be avoided, and the one-way channel can be obtained, thereby ensuring the single flow direction of the fluid in the one-way channel.

[0071] To sum up, in the first scheme, the through holes of the first partition plate 1 and the through holes of the second partition plate 2 are respectively located on both sides of the partition plate 4. The refrigerant enters the inside of the double-layer partition plate through the first through hole 11 of the first partition plate 1. Due to the misplacement of the cylinder body 3, the partition plate 4 and the upper and lower through holes, the refrigerant needs to go around the cylinder body 3 for about one week after entering the partition plate. When reaching the position of the second through hole 21 of the second partition plate 2, the liquid refrigerant leaves the partition plate through the second through hole 21 of the second partition plate 2 due to the action of gravity, while the gaseous refrigerant enters the inside of the cylinder body 3 through the third through hole 31 on the side wall of the cylinder body 3, achieving the effect of gas-liquid separation.

[0072] Further combining the first scheme, the first pipe 6 passes through the first hole 22 and its top end is placed in the middle of the cylinder body 3 near the first partition plate 1. Since there is no perforation in the first partition plate 1, it is avoided that the liquid-carrying refrigerant directly enters the first pipe 6; at the same time, when the gaseous refrigerant carries a small amount of liquid refrigerant into the inside of the cylinder body 3, due to the position of the upper end of the first pipe 6 near the first partition plate 1, it can also avoid the small amount of liquid refrigerant entering the cylinder body 3 from entering. The liquid refrigerant accumulated inside the cylinder body 3 will be discharged from the cylinder body 3 when it reaches the height of the third through hole 31 on the side wall of the cylinder body 3, and then discharged from the partition plate through the second through hole 21 of the second partition plate 2.

[0073] Similarly, for the second partition plate 2 in the integrated gas-liquid separation partition plate corresponding to the double-cylinder compressor, which has two perforations and two straight pipes, its gas-liquid separation principle remains unchanged.

[0074] Similarly, for the second scheme of the integrated gas-liquid separation partition plate, after the refrigerant enters the liquid distributor, the gaseous refrigerant enters the inside of the cylinder body 3 through the second pipe 13, and the small amount of liquid refrigerant carried accumulates at the bottom inside the cylinder body 3. The gaseous refrigerant reaches the upper space of the cylinder body 3 and reaches the outside of the cylinder body 3 through the third through hole 31 on the side wall of the cylinder body 3. Under the action of the partition plate 4, it goes around the cylinder body 3 for one week. The liquid refrigerant accumulates at the lower bottom outside the cylinder body 3 due to the action of gravity, and the gaseous refrigerant is discharged from the partition plate through the third pipe 23 and then enters the compressor to participate in the operation, realizing gas-liquid separation.

[0075] It should be noted that the integrated gas-liquid separation partition has a partitioned double-layer partition. The flow holes of the two partitions are located on both sides of the partition. After the refrigerant enters the liquid distributor, it needs to go around the cylinder body 3 for one week, increasing the gas-liquid separation path, improving the stiffness of the liquid distributor, and reducing vibration and noise. A cylinder body 3 is arranged between the two partitions of the integrated gas-liquid separation partition. The side of the cylinder body 3 is provided with holes. Due to the action of gravity, the liquid refrigerant enters the flow holes of the lower partition, and the gaseous refrigerant enters the cylinder body 3, further realizing gas-liquid separation and improving the gas-liquid separation rate. The top of the straight pipe of the integrated gas-liquid separation partition is placed below the upper partition and inside the cylinder body 3 in the middle of the double-layer partition, avoiding the direct entry of liquid refrigerant into the straight pipe and reducing the liquid carry-over in the exhaust of the liquid distributor. It can reduce the liquid refrigerant entering the straight pipe of the liquid distributor. During the operation of the compressor, when there is too much liquid refrigerant, the straight pipe inside the liquid distributor can prevent the liquid refrigerant from directly entering the pump body and prevent liquid hammer. By selecting the integrated gas-liquid separation partition, the situation of liquid refrigerant entering the straight pipe can be reduced, while not affecting the smooth entry of gaseous refrigerant into the straight pipe, reducing the liquid carry-over in the exhaust of the liquid distributor, improving the gas-liquid separation rate, stabilizing the air flow, reducing noise and vibration, and improving the energy efficiency of the compressor.
