[0002] The present application is based on Chinese Patent Application No. 202411365351.2, filed on September 26, 2024, and Chinese Patent Application No. 202422375549.0, filed on September 26, 2024, and claims priority to the aforementioned Chinese Patent Applications, the contents of which are incorporated herein by reference in their entirety. TECHNICAL FIELD

[0003] The present application relates to the field of compressors, and in particular to a pulsation valve, a vehicle horizontal rotary compressor, an air conditioning system and a vehicle. BACKGROUND

[0004] In the operation of an air conditioning system, refrigerant circulates through a circuit to achieve cooling or heating functions. However, regardless of the refrigerant used, the compressor as the core component of the system inevitably produces pressure fluctuations at its suction and discharge ends (also known as pressure sides), which are referred to as pressure pulsations. These pressure pulsations propagate along the refrigerant circuit, not only exciting the vibration of internal components of the system, but also causing noise generation.

[0005] Especially on vehicles, when these noises are transmitted to the heat exchanger located in the passenger cabin, since the heat exchanger has a large and flat surface, it becomes a loudspeaker or amplifier for these noises, further enhancing the intensity and propagation range of the noises.

[0006] Therefore, how to alleviate the pressure pulsation of the compressor is an important research direction to reduce the noise of the system. SUMMARY

[0007] The present application aims to at least partially solve one of the technical problems in the related art.

Embodiments of the present application

[0033] Embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0034] The pulsation valve 100 according to the first aspect of the present application is described below with reference to FIGS. 1-6.

[0035] It should be noted that the pulsation valve 100 of the present application is used in a compressor, which is used in an air conditioning system 2000 or a vehicle 3000 to meet the large load requirements of the air conditioning system 2000 or the vehicle 3000. The compressor has no specific use when used in the vehicle 3000, and can be applied to the air conditioning system 2000 to provide the compression power required for refrigeration or heating, and can also be flexibly configured in refrigerators, heat pump water heaters, new energy vehicle thermal management systems, and other devices. As shown in FIGS. 1 and 4, the pulsation valve 100 according to the embodiments of the present application includes a valve body 10, a valve core 20, an elastic member 30, and an adjusting member 40.

[0036] The valve body 10 is the main part of the entire pulsation valve 100, which is made of a material that is strong and durable to withstand high pressure and high temperature when the compressor exhausts. At the same time, a flow passage system is constructed inside the valve body 10 to control the gas.

[0037] As shown in FIGS. 1 and 4, the valve body 10 has an inlet wall 11, and the inlet wall 11 is provided with a valve body inlet 111. The valve body 10 is formed with a first flow passage 14 and a second flow passage 15, one end of the first flow passage 14 is communicated with the valve body inlet 111, and the second flow passage 15 is located at the outer circumferential side of the first flow passage 14.

[0038] The gas enters the pulsation valve 100 through the valve body inlet 111. Optionally, the size and shape of the valve body inlet 111 can be adjusted as needed to reduce turbulence and energy loss when the gas enters.

[0039] The valve body 10 has two main flow passages formed inside: a first flow passage 14 and a second flow passage 15. The first flow passage 14 serves as a main flow passage, and its diameter and length are designed according to the displacement and pulsation characteristics of the compressor. The second flow passage 15 is located on the outer circumferential side of the first flow passage 14, forming a surrounding structure. When the valve core 20 is in contact with the inlet wall 11, the second flow passage 15 is closed, thereby playing a throttling and pulsation suppression role.

[0040] It can be understood that the second flow passage 15 can be one or more. Multiple second flow passages 15 can be arranged at intervals along the circumference of the first flow passage 14, i.e., the direction around the central axis of the first flow passage 14. Among them, the central angle corresponding to the second flow passage 15 in the circumferential direction of the first flow passage 14 can be specifically set according to actual needs, while also achieving the limitation of the first flow passage 14 on the moving direction of the valve core 20, i.e., achieving the limiting of the first flow passage 14 and the valve core 20 in the radial direction of the first flow passage 14, facilitating the smooth movement of the valve core 20.

[0041] In combination with FIGS. 1-2 and 6, the valve core 20 is movably arranged in the first flow passage 14. When the valve core 20 is in contact with the inlet wall 11, the second flow passage 15 is closed. When the valve core 20 is separated from the inlet wall 11, a communication annular gap is formed therebetween, which communicates the valve body inlet 111 and the second flow passage 15. The valve core 20 is provided with a valve core through port 13, one end of which is opposite to the valve body inlet 111 and the other end of which communicates with the first flow passage 14 or the second flow passage 15. The flow area of the valve core through port 13 is smaller than that of the valve body inlet 111, so as to serve as a throttling passage.

[0042] The valve core 20 can have an open position for opening the inlet of the second flow passage 15 and a closed position for closing the inlet of the second flow passage 15, and can move between the open position and the closed position.

[0043] Specifically, when the pressure pulsation is small, the valve core 20 closely abuts against the inlet wall 11 to close the second flow passage 15. When the pressure pulsation increases, the valve core 20 is separated from the inlet wall 11 to form a communication annular gap, which allows the gas to be split through the second flow passage 15, thereby weakening the energy of the gas entering the first flow passage 14.

[0044] The diameter of the valve core 20 is slightly smaller than that of the first flow passage 14, so as to ensure that it can freely move in the flow passage without generating excessive frictional resistance. Optionally, the valve core 20 can be a cylindrical component.

[0045] The elastic member 30 is connected to the valve core 20, and is used to abut the valve core 20 against the inlet wall 11.

[0046] The elastic member 30 is an important component connecting the valve core 20 and the valve body 10, and its main function is to provide a pre-tightening force to keep the valve core 20 in contact with the inlet wall 11 when no external force is applied, thereby closing the second flow passage 15. The pre-tightening force of the elastic member 30 can be adjusted as needed to meet the gas control requirements in various working conditions. Alternatively, when the pulsation valve 100 is in a high-pressure, high-temperature, or corrosive medium environment, the pre-tightening force is adjusted to be larger, so that the contact between the valve core 20 and the inlet wall 11 is more closely, reducing the risk of leakage. Alternatively, in the case of faster response speed or lower operating force, such as low pressure, normal temperature, or low viscosity medium environment, the pre-tightening force can be appropriately adjusted to be smaller. In this way, the resistance of the valve core 20 during opening and closing can be reduced, and the response speed of the valve can be improved.

[0047] In some embodiments as shown in FIG. 1, FIG. 4, the elastic member 30 is a spring (such as a bolt spring, etc.); of course, the elastic member 30 can also be other components that have elasticity and can always push the valve core 20 to move in the direction of closing the second flow passage 15.

[0048] As shown in FIG. 1, the adjusting member 40 is connected to the elastic member 30, and the adjusting member 40 is movably connected to the valve body 10 to adjust the pre-tightening force of the elastic member 30 when moving.

[0049] The adjusting member 40 is a component movably connected to the valve body 10, and the adjusting member 40 can be a bolt or a slider, etc. The adjusting member 40 adjusts the pre-tightening force of the elastic member 30 by changing the connection point with the elastic member 30 or applying additional force, thereby achieving the best gas control effect.

[0050] In some optional embodiments, the adjusting member 40 is arranged at a position of the valve body 10 that is easy to access. For example, at least part of the adjusting member 40 extends to the outside of the pulsation valve 100. In this way, adjustment of the adjusting member 40 is facilitated. When it is necessary to increase the pre-tightening force, the adjusting member 40 is moved axially and close to the valve body inlet 111; when it is necessary to decrease the pre-tightening force, the adjusting member 40 is moved axially away from the valve body inlet 111.

[0051] Optionally, the adjusting member 40 is provided with marks, scales, etc. By providing clear marks or scales on the adjusting member 40, the pre-tightening force can be accurately adjusted.

[0052] Optionally, the adjusting member 40 further comprises a locking mechanism or an anti-loosening mechanism. In this way, it can be ensured that after adjustment is completed, a stable state can be maintained, preventing accidental changes due to vibration or external force, and improving the reliability of the pulsation valve 100.

[0053] As shown in FIG. 1, the pulsation valve 100 according to some embodiments of the present application, the valve body 10 comprises: a valve pipe body 16 and an outlet wall 12. The valve pipe body 16 is tubular, one end of the valve pipe body 16 is connected to the inlet wall 11, and the valve core 20 and the elastic member 30 are located in the valve pipe body 16; the outlet wall 12 is connected to the other end of the valve pipe body 16, and the valve body outlet 121 is arranged on the outlet wall 12, and the elastic member 30 abuts against the outlet wall 12.

[0054] In the above technical solution, the valve pipe body 16 serves as the main part of the pulsation valve 100, which is configured as a tubular structure. This tubular structure is conducive to the smooth flow of gas and provides sufficient space to accommodate components such as the valve core 20 and the elastic member 30. One end of the valve pipe body 16 serves as the inlet wall 11, which is used to connect or integrate into the gas system of the compressor, achieving seamless connection between the pulsation valve 100 and the gas system of the compressor. This not only ensures that the gas can enter the interior of the valve pipe body 16, but also effectively prevents gas leakage.

[0055] Optionally, a connecting flange, threaded interface or other form of connecting device can be arranged at the inlet wall 11 to facilitate connection with the compressor or other gas pipelines.

[0056] Optionally, the valve pipe body 16 is a high-strength, corrosion-resistant material piece. For example, the valve pipe body 16 can be a stainless steel material piece, an alloy steel material piece or a special engineering plastic piece to ensure its stability and durability in high-pressure, high-temperature or corrosive media.

[0057] The valve core 20 is located in the valve pipe body 16 and is a key component for controlling gas flow. It can move within the valve pipe body 16 according to the pressure of the gas, thereby opening or closing the valve body outlet 121 to regulate the flow or pressure of the gas.

[0058] The elastic member 30 abuts against the outlet wall 12 and exerts a certain pre-tightening force on the valve core 20. When the valve core 20 is moved by gas pressure or other external forces, the elastic member 30 can maintain the stability and rapid resetting capability of the valve core 20, ensuring the reliable closing of the valve.

[0059] Optionally, the elastic member 30 is a high-elasticity, corrosion-resistant material piece. For example, the elastic member 30 can be a stainless steel material piece, an alloy material piece, etc. By arranging a high-elasticity elastic member 30 and a corrosion-resistant elastic member 30, the adaptability and durability of the elastic member 30 in high-temperature, high-pressure and corrosive environment conditions are enhanced, thereby widening its effective working range and ensuring the working stability of the elastic member 30 under various working conditions, which in turn provides an important guarantee for the reliable operation of the pulsation valve 100.

[0060] As shown in FIG. 1, FIG. 3, FIG. 5, in some embodiments, the valve body outlet 121 comprises a central outlet 1211 and a peripheral outlet 1212 surrounding the periphery of the central outlet 1211.

[0061] The central outlet 1211 is located at the center of the valve body outlet 121, and is one of the main channels for gas flow, usually used to directly and efficiently guide the gas into the next processing stage. The peripheral outlet 1212 surrounds the periphery of the central outlet 1211 and forms an annular or approximately annular outlet area. This design allows the gas to flow out through the peripheral area in addition to the central path when flowing through the valve body 10, achieving more uniform flow distribution.

[0062] The space surrounded by the pipe wall of the valve pipe body 16 constitutes the first flow channel 14, and the end of the first flow channel 14 away from the valve body inlet 111 is connected to the central outlet 1211. The pipe wall of the valve pipe body 16 is provided with a second flow channel 15, and the end of the second flow channel 15 away from the valve body inlet 111 is connected to the peripheral outlet 1212.

[0063] In the embodiments of the present application, the pipe wall of the valve pipe body 16 not only provides structural support, but also defines different internal spaces, including the first flow channel 14 and the second flow channel 15. The first flow channel 14 extends from the valve body inlet 111 to the end away from the inlet, and finally connects to the central outlet 1211.

[0064] Specifically, when the gas enters the valve body 10, it will first enter the first flow channel 14 and flow along the pipe wall until it reaches the central outlet 1211, completing the main flow path.

[0065] In addition, the pipe wall of the valve pipe body 16 also includes the second flow channel 15, which increases the flow path of the gas in the valve body 10. This means that when the gas flows in the first flow channel 14, part of the gas can be guided to the peripheral outlet 1212 through these second flow channels 15, achieving gas shunting or specific direction flow, thereby reducing the flow of gas in the first flow channel 14.

[0066] Optionally, the position, number and shape of the second flow channel 15 can be designed according to specific needs, as long as the end of the second flow channel 15 away from the valve body inlet 111 is connected to the peripheral outlet 1212.

[0067] As shown in FIG. 1, FIG. 4, according to some embodiments of the pulse valve 100 of the present application, at least a part of the valve pipe body 16 constitutes a guide pipe section 161. The inner cross section of the guide pipe section 161 is consistent with the cross sectional shape of the valve core 20, so as to form a guide to the valve core 20.

[0068] In the above technical solution, the guide pipe section 161 becomes the main passage for the movement of the valve core 20. Since the inner cross section of the guide pipe section 161 is configured to be in a shape that is completely consistent with the cross sectional shape of the valve core 20, the valve core 20 can be ensured to closely fit the inner wall of the guide pipe section 161 during movement. The problem of deviation caused by excessive gap is reduced, and the consistency of the shape also ensures the stability of the valve core 20 during movement, ensuring that the valve core 20 moves smoothly along the predetermined trajectory, avoiding performance degradation caused by path deviation, or shaking or jamming during movement.

[0069] Optionally, the guide pipe section 161 is a high wear-resistant, corrosion-resistant, high-hardness piece. For example, the guide pipe section 161 can be a stainless steel piece, a ceramic piece, or a special alloy piece, etc. The use of these material pieces can improve the durability of the guide pipe section 161, ensuring that it can maintain good working condition in long-term high pressure, high temperature and corrosive environment.

[0070] As shown in FIG. 1, in some embodiments, the outer peripheral surface of the valve core 20 is connected to the end surface facing the inlet wall 11 through a chamfer surface 201. When the valve core 20 is in contact with the inlet wall 11, the chamfer surface 201 is surrounded by the valve pipe body 16 and the inlet wall 11 to form an angle cavity 17, and the angle cavity 17 is communicated with the second flow channel 15.

[0071] Firstly, by setting the chamfer surface 201, the contact between the outer peripheral surface of the valve core 20 and the inner wall of the valve pipe body 16 during movement is smoother, the contact area between the valve core 20 and the valve pipe body 16 is reduced, and the probability of friction and wear caused by excessive contact is reduced. This can prolong the service life of the valve core 20 and the valve pipe body 16, and also reduce the heat and noise generated by friction.

[0072] When the valve core 20 is closed, the end surface thereof facing the inlet wall 11 needs to closely fit the valve body inlet 111 or the related sealing surface to achieve sealing. The design of the chamfer surface 201 helps to ensure that the valve core 20 can smoothly transition to the sealing position during closing, reducing the risk of leakage caused by position deviation.

[0073] As shown in FIG. 4, in some embodiments, the first flow channel 14 and the second flow channel 15 are both located in the space surrounded by the pipe wall of the valve pipe body 16. The pulsation valve 100 further comprises: a support 18 connected to the outer peripheral side of the valve core 20, the support 18 is at least two and located in the second flow channel 15, and the adjacent two supports 18 are spaced apart.

[0074] By setting the support 18, additional support and stability are provided for the valve core 20, ensuring that it can maintain the correct position and posture during operation.

[0075] Firstly, the number of the supports 18 and the interval between adjacent supports 18 can be adjusted according to the design requirements and operating conditions of the pulsating valve 100. For example, more supports 18 can be arranged to provide stronger support. Alternatively, the number of the supports 18 can be reduced by increasing the interval between adjacent supports 18, which can reduce the flow resistance of the gas. By changing the number and distribution of the supports 18, the flow characteristics of the gas in the second flow channel 15 can be optimized, and the occurrence of vortex and turbulent flow can be reduced, thereby improving the efficiency and stability of the gas flow.

[0076] Secondly, during the operation of the pulsating valve 100, the spool 20 can be slightly displaced or vibrated due to the influence of various factors such as gas pressure and vibration. The presence of the supports 18 can effectively limit the amplitude of these displacements and vibrations, and improve the dynamic stability of the spool 20.

[0077] In some embodiments, as shown in FIG. 4, a part of the support 18 extends to the side of the spool 20 away from the inlet wall 11, and when the spool 20 moves towards the outlet wall 12, the support 18 can abut against the outlet wall 12 to fix the spool 20.

[0078] In the above technical solution, when the spool 20 is displaced towards the outlet wall 12 under the action of the gas pressure, the extended part of the support 18 can abut against the outlet wall 12. In this way, an abutting mechanism is formed, which not only limits the further displacement of the spool 20, but also fixes the spool 20 at a specific position through physical contact.

[0079] After the support 18 abuts against the outlet wall 12, a stable support point is also provided for the spool 20, which prevents accidental displacement of the spool 20 due to gas pressure fluctuations, vibration or other external factors, and thus ensures the accurate control and stable operation of the pulsating valve 100.

[0080] In some embodiments, in combination with FIG. 4 and FIG. 6, the adjusting member 40 includes a first adjusting member 41, which is threadedly connected to the valve pipe body 16, and the first adjusting member 41 is provided with a valve body inlet 111.

[0081] The valve body inlet 111 formed on the first adjusting member 41 is the main channel for the gas to enter the valve pipe body 16, which can ensure that the gas can smoothly and stably enter the inside of the valve pipe body 16.

[0082] Optionally, the valve body inlet 111 is provided with a filtering device. In this way, impurities can be prevented from entering.

[0083] The outer circumferential surface of the first adjusting member 41 is provided with an external thread structure, and the inside of the valve pipe body 16 is provided with an internal thread structure matched with the external thread structure. The thread connection between the first adjusting member 41 and the valve pipe body 16 can be realized through the connection of the external thread structure and the internal thread structure. This thread connection mode can improve the sealing performance of the valve body 10, prevent gas leakage, and also allow convenient disassembly and reassembly when needed.

[0084] In some embodiments, as shown in FIG. 4, the adjusting member 40 includes a second adjusting member 42, which is threadedly connected to the valve pipe body 16, and the valve body outlet 121 is provided on the second adjusting member 42.

[0085] The second adjusting member 42 has an external thread segment, and the valve pipe body 16 has an internal thread segment. The second adjusting member 42 and the valve pipe body 16 are threadedly connected through the external thread segment and the internal thread segment. This design ensures that the second adjusting member 42 can be stably fixed on the valve pipe body 16 and allows its position to be adjusted by rotation.

[0086] The valve body outlet 121 opened on the second adjusting member 42 is a passage for gas to exit the valve pipe body 16. Optionally, the size, shape, and position of the valve body outlet 121 can be designed according to specific application requirements to ensure that the gas can exit the valve pipe body 16 at a predetermined flow rate, flow, and pressure. Optionally, the valve body outlet 121 can be equipped with a filter screen or the like to meet specific process requirements.

[0087] According to some embodiments of the pulsation valve 100 of the present application, the elastic member 30 is a spring and is located inside the valve body 10, as shown in FIGS. 1 and 4.

[0088] The spring plays a role in dynamic adjustment in the pulsation valve 100. When the valve needs to be opened or closed, by controlling the external force such as gas pressure and balancing with the force of the spring, the rapid response and control of the valve can be realized. This dynamic adjustment capability enables the pulsation valve 100 to flexibly adjust the gas mass flow during the working cycle of the compressor, thereby meeting various needs.

[0089] Moreover, the elastic properties of the spring can also provide buffering and damping effects for the pulsation valve 100. During the rapid opening or closing of the valve, the spring can absorb and disperse part of the impact energy, reducing the vibration and noise of the valve and the support 18.

[0090] Secondly, the presence of the spring also helps to ensure the sealing performance of the valve. Through the pre-tightening force of the spring, the valve can tightly fit the sealing surface in the closed state, preventing gas leakage. At the same time, during the opening of the valve, the elasticity of the spring can also help to maintain a certain sealing pressure, improving the sealing effect.

[0091] Optionally, the spring has a spring constant E, and 0.1 N / mm ≤ E ≤ 1.1 N / mm. Optionally, the spring constant E of the spring can be 0.1 N / mm, 0.3 N / mm, 0.5 N / mm, 0.8 N / mm, 1 N / mm, or 1.1 N / mm. A proper spring constant can ensure the response speed of the valve core 20, while avoiding a large pressure loss when the valve core 20 is opened.

[0092] Optionally, the spring is a stainless steel spring, an alloy spring, or other spring with high wear resistance.

[0093] According to the vehicle horizontal rotary compressor 1000 of the second aspect of the present application, referring to FIG. 7, the vehicle horizontal rotary compressor 1000 comprises the pulsation valve 100 of the vehicle horizontal rotary compressor 1000 of the first aspect of the present application, and further comprises a compression chamber, and the pulsation valve 100 is arranged in the exhaust flow channel of the compression chamber.

[0094] The compression chamber is the main place for gas compression, and the pulsation valve 100 is arranged at the outlet side of the compression chamber, that is, after the completion of the compression process, the gas first passes through the pulsation valve 100 and then is discharged from the vehicle horizontal rotary compressor 1000. This layout enables the pulsation valve 100 to directly act on the high-pressure gas about to be discharged, so as to adjust the flow characteristics thereof. Specifically, after the dynamic adjustment function of the pulsation valve 100, the discharged high-pressure gas can be discharged more smoothly and continuously, reducing the pressure impact and vibration caused by the sudden release of the gas. This smooth exhaust process not only reduces the amplitude and frequency of the exhaust pulsation, but also reduces the mechanical vibration and noise radiation caused by the pulsation.

[0095] Therefore, by arranging the pulsation valve 100 in the exhaust flow channel of the compression chamber, the vehicle horizontal rotary compressor 1000 of the present application can significantly reduce the exhaust pulsation and the system noise caused thereby.

[0096] Specifically, the pulsation valve 100 is used in the vehicle horizontal rotary compressor 1000, the vehicle horizontal rotary compressor 1000 comprises a compression mechanism 101 for compressing refrigerant, and the pulsation valve 100 is arranged on the compression mechanism 101.

[0100] In some embodiments, the vehicle horizontal rotary compressor 1000 includes a compression mechanism 101, an end cover, and a bracket, the bracket connecting the compression mechanism 101 and the end cover. At this time, the compression mechanism 101 includes a first cylinder 1011, a second cylinder 1012, a partition 1013, a first bearing 1014, and a second bearing 1015, the first cylinder 1011, the second cylinder 1012, and the partition 1013 are located between the first bearing 1014 and the second bearing 1015, and the partition 1013 is located between the first cylinder 1011 and the second cylinder 1012.

[0101] It can be understood that the bracket in the embodiments provided by the present application can be arranged inside the vehicle horizontal rotary compressor 1000 or partially exposed outside the vehicle horizontal rotary compressor 1000.

The number of the pulsation valve 100 is not limited, and the specific position is not limited.

[0104] In some embodiments, the refrigerant medium used by the vehicle horizontal rotary compressor 1000 is carbon dioxide, and the vehicle horizontal rotary compressor 1000 is a carbon dioxide compressor. Of course, the refrigerant used by the vehicle horizontal rotary compressor 1000 is not limited to this. The refrigerant medium used by the vehicle horizontal rotary compressor 1000 is carbon dioxide, which has many advantages.

[0105] Carbon dioxide has a relatively high suction and discharge pressure compared to traditional refrigerants. The vehicle horizontal rotary compressor 1000 of the embodiments of the present application can meet the sealing requirements when carbon dioxide is used as a refrigerant. Carbon dioxide has good thermodynamic properties, so when the same refrigeration capacity is required, the use of carbon dioxide as a refrigerant does not require a large volume of the compression chamber, which can reduce the volume and weight of the entire compressor. In addition, the compressor using carbon dioxide can operate in a wide pressure range, whether it is preliminary compression in a low-pressure environment or deep compression in a high-pressure environment, and can exhibit stable performance. Therefore, the vehicle horizontal rotary compressor 1000 of the present application can obtain an optimized compression ratio, has high cooling performance when used in a refrigeration system, can reduce energy consumption, and improve energy utilization.

[0106] When a large compression ratio is obtained by using a carbon dioxide compressor, the compressor may have abnormal phenomena such as surge and vibration, which affects the normal operation of the system. In addition, high compression ratio may also cause the pressure fluctuation of the system to increase, which affects the normal work of other equipment. Therefore, the structure of the pulsation valve 100 is improved in the application scheme to improve the vibration and noise problems caused by using carbon dioxide as the refrigerant medium to obtain a high compression ratio. Of course, the application scheme can solve the vibration and noise problems of the vehicle horizontal rotary compressor 1000 using carbon dioxide as the refrigerant medium, and also can solve the vibration and noise problems of the vehicle horizontal rotary compressor 1000 using other refrigerant medium. Since carbon dioxide is used as the refrigerant medium to obtain a high compression ratio, the noise reduction effect of the application scheme will be more obvious on the vehicle horizontal rotary compressor 1000 using carbon dioxide.

[0107] According to the air conditioning system 2000 of the third aspect of the application, referring to FIG. 8, it comprises the vehicle horizontal rotary compressor 1000 according to the first aspect of the application. Therefore, it is beneficial to reduce the noise of the air conditioning system 2000.

[0109] According to the vehicle 3000 of the fourth aspect of the application, referring to FIG. 8, it comprises the air conditioning system 2000 of the third aspect of the application or the vehicle horizontal rotary compressor 1000 of the second aspect of the application, and the structure of the vehicle horizontal rotary compressor 1000 and the air conditioning system 2000 will not be repeated here.

At the same time, the vehicle horizontal rotary compressor 1000 has a low noise level, which can create a quiet riding environment in the vehicle, and further improve the riding experience of passengers.

[0111] For example, the vehicle 3000 comprises an air conditioning system 2000, and the air conditioning system 2000 uses the vehicle horizontal rotary compressor 1000 according to the above-mentioned embodiments of the application to realize refrigerant circulation.

[0112] In some embodiments, the vehicle 3000 can be a new energy vehicle 3000. The new energy vehicle 3000 can be a pure electric vehicle 3000 with an electric motor as the main driving force, or the new energy vehicle 3000 can also be a hybrid vehicle 3000 with an internal combustion engine and an electric motor as the main driving force.
