[0002] At present, the compressor separator is an important part of the operation of the compressor and air-conditioning system. The main function of the compressor separator is to prevent the liquid refrigerant in the refrigeration system from entering the compressor, thereby protecting the compressor from liquid hammer damage. Liquid hammer refers to the situation when the compressor sucks in liquid refrigerant, because the liquid is incompressible, causing serious impact and damage to the internal mechanical parts of the compressor. The separator is usually installed between the evaporator and the compressor suction pipe to separate the liquid and gaseous parts of the refrigerant mixture coming out of the evaporator. The separated liquid refrigerant will be guided back to the low-pressure side of the system, or after proper treatment, it will enter the evaporator for re-evaporation, while the gaseous refrigerant will enter the compressor to continue the compression cycle. Through the role of the separator, the reliability and efficiency of the system can be improved and the service life of the compressor can be extended. When the existing separator is working, the refrigerant enters the separator from the air inlet pipe for gas-liquid separation.

[0003] However, the air outlet of the air inlet pipe of the liquid separator in the prior art is located above the air inlet of the air outlet pipe of the liquid separator and is arranged relatively relatively, which will cause part of the fluid that has not been separated from the gas and liquid to directly enter the air inlet pipe, thereby making the gas-liquid separation effect of the separator poor.

[0040] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0041] like Figures 1 to 6 As shown, the first embodiment of the present invention provides a liquid separator, which includes: a housing 10, a partition 20, an inlet pipe 30 and an outlet pipe 40, wherein the housing 10 has an inlet 11, an outlet 12 and a liquid separation chamber 13 connected to both the inlet 11 and the outlet 12. The partition 20 is arranged in the liquid separation chamber 13, and a flow hole is arranged on the partition 20. The inlet pipe 30 and the outlet pipe 40 are both penetrated on the partition 20, the inlet pipe 30 is installed at the inlet 11, and the outlet pipe 40 is installed at the outlet 12, the outlet end of the inlet pipe 30 is located below the partition 20, and the inlet end of the outlet pipe 40 is located above the partition 20.

[0042] With the liquid separator provided in this embodiment, the gas-liquid mixed fluid enters the liquid separation chamber 13 through the outlet end of the inlet pipe 30, and the gas-liquid mixed fluid is first separated by gas and liquid under the action of gravity, and then part of the liquid will settle to the bottom of the shell 10, and part of the gas and the gas-liquid mixture will rise to the partition 20, and be separated again under the action of the partition 20, and then the fluid obtained after the separation again (including part of the gas and a small part of the gas-liquid mixture) will enter the outlet end of the outlet pipe 40 above the partition 20, and be discharged through the outlet pipe 40. The above separation process not only makes full use of gravity separation, but also effectively guarantees the gas-liquid separation stroke, so as to facilitate the effective guarantee of the gas-liquid separation effect. The liquid separator in this embodiment can be applied to the gas-liquid separation in the refrigeration system or the air-conditioning system, and improves the operating efficiency and stability of the system. In practical applications, this design significantly reduces the risk of liquid refrigerant entering the compressor, avoids the liquid hammer phenomenon, thereby protecting the compressor, reducing the maintenance cost and failure rate of the system, and is widely used in various air conditioners and refrigeration equipment for households, commerce and industry. Therefore, the separator provided in this embodiment can solve the technical problem of poor gas-liquid separation effect of the liquid separator in the prior art.

[0043] It should be noted that the gas-liquid mixed fluid entering the liquid separation chamber 13 through the inlet pipe 30 is mainly refrigerant.

[0044] In this embodiment, the liquid separator further includes a filter screen 50, which is installed at the flow hole. Such a structural arrangement can facilitate further improving the gas-liquid separation effect. In addition, by installing the filter screen 50 on the partition 20, the integration of the structure can be improved and the difficulty of installation can be reduced. The arrangement of the filter screen 50 can effectively filter out part of the liquid, preventing the liquid from entering the subsequent system, such as the compressor, through the outlet pipe 40, thereby avoiding damage to key components such as the compressor and extending the service life of the entire system.

[0045] Specifically, the partition 20 is provided with a first insertion hole 21 adapted to the inlet pipe 30, and there are multiple circulation holes, which are arranged at intervals along the periphery of the first insertion hole 21. There are multiple filter screens 50, and the multiple filter screens 50 are arranged one-to-one with the multiple circulation holes, and each filter screen 50 is installed at the corresponding circulation hole. With such a structural arrangement, it is convenient to improve the separation effect of the liquid and effectively improve the gas-liquid separation effect. This design of multiple circulation holes and multiple filter screens 50 increases the contact area of ​​gas-liquid separation and improves the separation efficiency. Specifically, the first insertion hole 21 can facilitate the effective fixing and limiting of the inlet pipe 30.

[0046] In this embodiment, the filter screen 50 is a planar mesh structure, so as to effectively improve the gas-liquid separation effect. Compared with the filter screen 50 with an arc-shaped bulge, the planar mesh structure is often less likely to cause liquid to block the mesh holes and the filter screen 50 to rupture, and thus is less likely to cause the compressor performance to decline. At the same time, the filter screen 50 with a planar mesh structure can distribute the airflow more evenly and reduce the airflow resistance, and is suitable for occasions that require high-efficiency separation and low resistance, such as large industrial refrigeration systems.

[0047] Specifically, there are at least two outlets 12, at least two outlet pipes 40, at least two outlet pipes 40 are arranged in one-to-one correspondence with at least two outlets 12, and each outlet pipe 40 is installed at the corresponding outlet 12. With such a structural arrangement, it is convenient to discharge gas through at least two outlet pipes 40. The design of each outlet pipe 40 can disperse the pressure of gas discharge and reduce the burden of a single outlet pipe 40, which is suitable for occasions where gas needs to be discharged quickly and evenly, such as commercial refrigeration equipment that needs rapid refrigeration. Specifically, the design of each outlet pipe 40 can cooperate with the arrangement of multiple cylinders of the compressor, thereby realizing the suction process of cylinders with more than two cylinders.

[0048] In this embodiment, one of the at least two outlet pipes 40 is located on one side of the inlet pipe 30, and the other of the at least two outlet pipes 40 is located on the other side of the inlet pipe 30. In this way, the spatial structural layout of the at least two outlet pipes 40 is optimized. This layout can better utilize the space of the liquid separation chamber 13, so that the gas is more evenly distributed in the chamber, the separation effect is improved, and the situation that the at least two outlet pipes 40 are distributed on one side, resulting in a large gas loss on the corresponding side and the inhalation of part of the liquid is avoided.

[0049] Specifically, the portion of the inlet pipe 30 located in the liquid separation chamber 13 is a straight pipe. With such a setting, the straight pipe design reduces the friction resistance of the fluid in the pipe, making the fluid flow smoother, and is suitable for occasions requiring low resistance flow, such as high-efficiency refrigeration systems, thereby reducing energy consumption and improving the overall energy efficiency of the system.

[0050] Specifically, the portion of the outlet pipe 40 located in the liquid separation chamber 13 is a straight pipe. In this way, the straight pipe design reduces the friction resistance of the fluid in the pipe, making the fluid flow smoother, and is suitable for occasions requiring low resistance flow, such as high-efficiency refrigeration systems, thereby reducing energy consumption and improving the overall energy efficiency of the system.

[0051] In this embodiment, the inlet 11 and the outlet 12 are arranged oppositely, and the partition 20 is provided with a first insertion hole 21 and a second insertion hole 22 at intervals, the first insertion hole 21 is adapted to the inlet pipe 30, and the second insertion hole 22 is adapted to the outlet pipe 40, the first insertion hole 21 is arranged oppositely to the inlet 11, and the second insertion hole 22 is arranged staggered with the outlet 12, and the portion of the outlet pipe 40 located in the liquid separation chamber 13 is a bent pipe section 42. With such a structural arrangement, it is convenient to improve the symmetry of the overall layout of the liquid dispenser, optimize the overall center of gravity distribution position of the liquid dispenser, and avoid the situation where the center of gravity of the inlet pipe 30 and the outlet pipe 40 has a greater influence on the overall center of gravity of the liquid dispenser due to the staggered arrangement of the first insertion hole 21 and the second insertion hole 22, thereby facilitating the installation of the liquid dispenser and improving the installation stability of the liquid dispenser.

[0052] Specifically, the second insertion hole 22 can facilitate the effective fixing and positioning of the outlet pipe 40 .

[0053] Specifically, the height of the partition 20 is h, and the height of the outlet pipe 40 extending above the partition 20 is s; 1 / 5≤s / h≤1 / 2. This height ratio design can ensure that the liquid in the gas-liquid mixture has enough time and space to settle, improve the gas-liquid separation effect, and ensure the smooth discharge of the gas, avoiding the risk of the liquid being carried out by the gas. It is suitable for occasions that need to balance the gas-liquid separation efficiency and system operation resistance, such as air conditioning systems.

[0054] In this embodiment, the height of the partition 20 is h, the height of the inlet pipe 30 extending below the partition 20 is m, and 1 / 5≤m / h≤1 / 2. With such a setting, it can be ensured that the liquid in the gas-liquid mixture has enough time and space to settle, thereby improving the gas-liquid separation effect.

[0055] Specifically, the distance between the top of the partition 20 and the bottom of the shell 10 is H1, and the height of the shell 10 is H0, 1 / 3≤H1 / H0≤2 / 3. This design ensures that the liquid separation chamber 13 has sufficient depth, so that the liquid has sufficient space to settle, and at the same time, the outlet pipe 40 is within a moderate length range, avoiding the pressure loss of the fluid that is easily increased due to the outlet pipe 40 being too long (the outlet pipe 40 here is too long mainly refers to the part of the outlet pipe 40 located in the liquid separation chamber 13 is too long). Specifically, since the fluid entering the outlet pipe 40 is mainly gaseous refrigerant, the pressure loss of the gaseous refrigerant will increase, especially when there is a lot of refrigerant flowing in the pipeline, the friction resistance will also increase, which may reduce the suction pressure of the compressor and increase the compressor power, affecting the working efficiency and refrigeration capacity of the compressor. On the contrary, when the outlet pipe 40 is too short (the outlet pipe 40 here is too short mainly refers to the part of the outlet pipe 40 located in the liquid separation chamber 13 is too short), the liquid in the refrigerant may not have enough time to separate from the gas, thereby increasing the risk of liquid entering the compressor, resulting in the occurrence of liquid hammer.

[0056] Specifically, the outlet pipe 40 includes a straight pipe section 41 and a curved pipe section 42. The straight pipe section 41 is located in the liquid separation chamber 13 and can be a steel pipe. The straight pipe section 41 and the curved pipe section 42 are connected at the outlet 12. Specifically, the straight pipe section 41 and the curved pipe section 42 are welded at the outlet 12.

[0057] The liquid separator in this embodiment eliminates the filter screen 50 structure in the traditional liquid separator and adopts a new gas-liquid separation principle design, which can accurately control the gas-liquid flow path inside the liquid separator. Compared with the traditional liquid separator, the liquid separator in this embodiment can effectively utilize gravity to further achieve efficient gas-liquid separation and reduce the situation where the gas-liquid separation mainly relies on the filter screen 50. This improvement not only simplifies the internal structure of the liquid separator, reduces the pressure drop and suction fluctuation, improves the effective volume of the liquid separator and the energy efficiency of the system, but also solves the problem that the traditional filter screen 50 is easily blocked and broken, greatly improving the reliability and service life of the system. This innovation makes the liquid separator more suitable for the application requirements of high-performance compressors and complex refrigeration systems.

[0058] like Figure 1The figure shows a liquid separator provided by an embodiment of the present invention, wherein the shell 10 includes an upper cover 14, a cylinder 15 and a lower cover 16 which are connected in sequence. The partition 20 separates the liquid separator into two parts, an upper part and an lower part. The inlet pipe 30 is a straight pipe. The inlet pipe 30 is connected to the air conditioning system. When the compressor is running, the gas-liquid two-phase refrigerant is sucked into the liquid separator through the inlet pipe 30. When the gas-liquid two-phase refrigerant enters the liquid separator, the gas-liquid mixture will automatically separate due to gravity. Impurities and large molecular liquid refrigerants will quickly settle to the bottom of the liquid separator due to their large density, while the gaseous refrigerant will pass through the partition 20 and return to the upper part of the liquid separator. Specifically, the structure of the partition 20 is as follows: Figure 2 As shown, a plane filter 50 is provided on the partition 20, and the filter 50 can further filter the small molecule liquid refrigerant. Finally, the gaseous refrigerant is sucked into the compressor pump body by the steel pipe at the upper part of the liquid separator to achieve compression, and the length of the steel pipe of this liquid separator is significantly shortened compared with the traditional liquid separator steel pipe (compared with the existing steel pipe length shortened by 20% to 50%), which helps to reduce the suction resistance distance and suction fluctuations, and reduce the power consumption of the compressor. The new liquid separator can effectively complete the gas-liquid separation under the condition of gravity as the main force and the partition 20 filter 50 as the auxiliary force, and solves the blockage problem caused by the traditional filter 50. In addition, this design of eliminating the traditional liquid separator filter 50 bracket greatly simplifies the structure of the liquid separator, thereby reducing the pressure drop between the internal components and further improving the overall efficiency of the system. At the same time, since the liquid separator no longer mainly relies on the filter 50 to separate the gas-liquid two-phase mixture, its applicable working condition range is also expanded, and it can operate stably in more complex and harsh working environments. This design is particularly suitable for high-performance compressors and modern complex refrigeration systems, such as industrial refrigeration equipment, air-conditioning systems, and heat pump devices, and can significantly improve the operating efficiency and reliability of the system.

[0059] Specifically, the filter screen 50 ensures the filtration of small molecular liquids of corresponding sizes. When the compressor is running, the gas-liquid two-phase refrigerant is sucked into the liquid separator through the straight pipe. When the gas-liquid two-phase refrigerant enters the liquid separator, the gas-liquid mixture will automatically separate according to the action of gravity: impurities in the refrigerant and large molecular liquid refrigerant will quickly settle to the bottom of the liquid separator due to their high density, while the gaseous refrigerant will pass through the partition 20 and return to the upper part of the liquid separator. The gaseous refrigerant is sucked into the compressor pump body through the steel pipe at the upper part of the liquid separator to achieve compression.

[0060] like Figure 5 As shown, the principle of separating gas-liquid two-phase refrigerant in a liquid separator in another embodiment of the present invention is the same as that in the previous embodiment. In this embodiment, it is a single-suction liquid separator, the liquid separator has only one outlet pipe 40, and a second insertion hole 22 is opened on the partition 20. In this embodiment, multiple filter screens 50 are provided, and the multiple filter screens 50 are arranged at intervals around the periphery of the first insertion hole 21.

[0061] like Figure 6As shown, the filtering principle of the filter screen 50 in the liquid dispenser in another embodiment of the present invention is the same as the above embodiment, except that the shapes of the flow holes opened on the partition 20 are different, specifically, they can be circular, square, etc., and the holes of the filter screen 50 with combined shapes are all within this embodiment. In this embodiment, a plurality of filter screens 50 are provided, and the plurality of filter screens 50 are arranged at intervals around the periphery of the first plug-in hole 21. A portion of the plurality of filter screens 50 has a larger filtering area, and the filtering shape is adapted to the outer edge of the partition 20 and the outer edge shape of the second plug-in hole 22, and another portion of the plurality of filter screens 50 has a smaller filtering area to adapt to the gap between two adjacent filter screens 50 with larger filtering areas, so as to improve the compactness of the structural layout of the plurality of filter screens 50, facilitate to ensure the filtering effect, and also ensure the structural strength of the partition 20.

[0062] Embodiment 2 of the present invention provides a compressor assembly, and the compressor assembly includes: the liquid separator and the compressor provided above, and the air intake of the compressor is connected to the outlet pipe 40 of the liquid separator. By arranging the liquid separator in front of the compressor, the liquid refrigerant can be effectively prevented from entering the compressor, the liquid hammer phenomenon can be avoided, the normal operation of the compressor can be protected, and the service life of the compressor can be extended. It is suitable for all refrigeration or air-conditioning systems that need to use a compressor, such as commercial freezers, household air conditioners, industrial cooling systems, etc., which significantly improves the stability and efficiency of the system and provides strong support for the optimization of the refrigeration system. In practical applications, this compressor assembly can greatly reduce the system maintenance cost, improve the continuity and reliability of operation, and is an indispensable part of modern refrigeration technology. Especially in occasions where frequent startup and shutdown are required, such as commercial refrigeration display cabinets, this component can effectively reduce the startup impact of the compressor, extend the service life of the compressor, reduce the overall cost of ownership of the equipment, and improve the economic benefits of commercial operations.

[0063] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: the liquid separator eliminates the filter structure in the traditional liquid separator and adopts an innovative gas-liquid separation design, which reduces the cost of the liquid separator while ensuring that the liquid separator has a good gas-liquid separation effect, so that the gas-liquid two-phase refrigerant is completely separated under the action of gravity and the partition filter. It solves the problem of poor gas-liquid separation in the liquid separator leading to wet compression of the compressor and reduced refrigeration capacity; it solves the problem of liquid suction and liquid impact in the compressor causing damage to the pump body parts of the compressor; it solves the problem of increased pressure loss and increased friction resistance in the liquid separator steel pipe being too long, causing unstable operation of the compressor; it solves the problem that the arc-shaped bulge of the existing filter is easily blocked by gas and liquid in the sieve holes and the filter ruptures, causing the performance of the compressor to decline; it eliminates the filter assembly and reduces the cost of the compressor.
