Description

Technical Field

[0001] This utility model relates to the field of compressor equipment technology, and more specifically, to a compressor and refrigeration equipment. Background Technology

[0002] Currently, scroll compressors typically include a housing and a compression mechanism consisting of a fixed scroll component and a moving scroll component. The fixed scroll component includes a fixed scroll end plate and fixed scroll blades, while the moving scroll component includes a moving scroll end plate and moving scroll blades. A compression chamber is formed between the moving scroll blades and the fixed scroll blades.

[0003] In related technologies, a flow passage is typically installed on the end plate of the fixed scroll near the exhaust port to transfer the pressure of the compression chamber to the intermediate pressure chamber. However, to accommodate the compressor's operating range and ensure sufficient pressure to seal the top and bottom of the scroll teeth even at low suction pressures, the pressure in the intermediate pressure chamber is generally set relatively high. This results in the pressure in the intermediate pressure chamber exceeding the actual required pressure at the rated point, leading to an excessively large axial sealing force and increased frictional power consumption. Utility Model Content

[0004] The embodiments of this utility model are intended to at least solve one of the technical problems existing in the prior art.

[0005] Therefore, a first aspect of the embodiments of this utility model provides a compressor.

[0006] A second aspect of the present invention provides a refrigeration device.

[0007] In view of the above, according to a first aspect of the present invention, a compressor is provided, the compressor comprising: a housing; a compression structure disposed within the housing, the compression structure comprising: a moving disc; a stationary disc assembly engaging with the moving disc, the stationary disc assembly having a back pressure chamber on the side opposite to the moving disc; and a pressure regulating mechanism for regulating the pressure of the back pressure chamber, the pressure regulating mechanism comprising a pressure regulating chamber communicating with the back pressure chamber, wherein the pressure within the pressure regulating chamber is adjustable.

[0008] The compressor provided in this embodiment includes a housing, a compression structure, and a pressure regulating mechanism. Specifically, a stationary disc assembly and a moving disc mesh. Optionally, the stationary disc assembly and the moving disc form a compression chamber. During compressor operation, the moving disc can rotate relative to the stationary disc assembly to compress the refrigerant in the compression chamber. When the refrigerant pressure in the compression chamber reaches the discharge pressure, the compressed high-temperature and high-pressure refrigerant is discharged from the discharge port of the stationary disc assembly, thus realizing the compression and discharge process.

[0009] The stationary disc assembly has a back pressure chamber on the side away from the moving disc. It can be understood that the pressure in the back pressure chamber is generally the intermediate pressure, that is, the pressure in the back pressure chamber is greater than the intake pressure and less than the exhaust pressure, thereby providing axial force to the stationary disc assembly in the axial direction.

[0010] In related technologies, flow passages are typically provided on the fixed scroll end plate to transfer the pressure from the compression chamber to the intermediate pressure chamber. The pressure in the intermediate pressure chamber is calculated as the suction pressure multiplied by a coefficient, which is primarily related to the refrigerant's polytropic index and the position of the flow passages. Because the compressor's operating range needs to be considered, this coefficient is generally set relatively large. This results in the intermediate pressure chamber pressure exceeding the actual required pressure at the compressor's rated point, leading to an excessively high axial sealing force and additional frictional power consumption.

[0011] The pressure regulating mechanism is used to adjust the pressure in the back pressure chamber. Specifically, the pressure regulating chamber is connected to the back pressure chamber. This means that the method of drawing pressure from the compression chamber to the intermediate pressure chamber in related technologies has been changed; instead, pressure is drawn from the pressure regulating chamber to the back pressure chamber. Since the pressure in the pressure regulating chamber is adjustable, the pressure in the chamber can be adjusted according to the actual operating conditions of the compressor, thereby adjusting the pressure in the back pressure chamber. This allows for matching a suitable back pressure for each operating condition of the compressor, thus optimizing the axial sealing force, preventing leakage, and reducing ineffective frictional work.

[0012] Specifically, when the compressor operates under harsh conditions, a larger axial sealing force is required. A higher pressure is regulated in the pressure regulating chamber and supplied to the back pressure chamber to achieve axial sealing between the stationary and moving disc assemblies, preventing leakage. When the compressor operates under mild conditions, a smaller axial sealing force is required. A lower pressure is regulated in the pressure regulating chamber and supplied to the back pressure chamber. This achieves axial sealing between the stationary and moving disc assemblies while avoiding excessive axial sealing force, effectively reducing additional frictional power consumption and improving the overall energy efficiency of the compressor.

[0013] In some technical solutions, the stationary disc assembly may optionally include a back pressure channel, which is connected to the back pressure chamber. The pressure regulating mechanism may also include a flow guiding assembly, one end of which is connected to the stationary disc assembly and the other end of which is connected to the pressure regulating chamber. The flow guiding assembly includes a flow guiding channel, and the two ends of which are connected to the back pressure channel and the pressure regulating chamber, respectively.

[0014] In this technical solution, specifically, when the compressor is operating under harsh conditions, a larger axial sealing force is required. A higher pressure is adjusted by the pressure regulating chamber. The higher-pressure gas flows from the pressure regulating chamber through the guide channel and the back pressure channel in sequence, and finally flows into the back pressure chamber, thereby providing a larger axial sealing force for the stationary plate assembly, realizing the axial seal between the stationary plate assembly and the moving plate, and preventing leakage.

[0015] When the compressor operates under mild conditions, a smaller axial sealing force is required. A lower pressure is regulated by the pressure regulating chamber. The lower-pressure gas flows from the pressure regulating chamber through the guide channel and the back pressure channel, and finally flows into the back pressure chamber. This provides a smaller axial sealing force for the stationary plate assembly, achieving axial sealing between the stationary plate assembly and the moving plate while avoiding excessive axial sealing force. This effectively reduces additional frictional power consumption and helps improve the overall energy efficiency of the compressor.

[0016] In some technical solutions, the flow area of ​​the guide channel may optionally be smaller than the flow area of ​​the back pressure channel.

[0017] In this technical solution, since the flow area of ​​the guide channel is smaller than that of the back pressure channel, a suitable back pressure can be matched according to the actual operating conditions of the compressor. This optimizes the axial sealing force while reducing the flow resistance when introducing gas into the back pressure chamber. When the compressor switches between different operating conditions, the matching back pressure can be quickly introduced, which is beneficial to improving the energy efficiency of the compressor.

[0018] In some technical solutions, optionally, the flow guiding channel includes a first flow channel, a second flow channel, and a third flow channel, and the flow guiding assembly also includes a first connector, a second connector, and a flow guiding pipe. The first connector is connected to the stationary plate assembly, the first flow channel is located at the first connector and communicates with the back pressure channel, the second connector is connected to the pressure regulating chamber, the second flow channel is located at the second connector and communicates with the pressure regulating chamber, the flow guiding pipe is located between the first connector and the second connector, and both ends of the flow guiding pipe are connected to the first connector and the second connector, respectively, and the third flow channel is located at the flow guiding pipe, and both ends of the third flow channel are connected to the first flow channel and the second flow channel, respectively.

[0019] Specifically, in this technical solution, when the compressor is operating under harsh conditions, a larger axial sealing force is required. A higher pressure is adjusted through the pressure regulating chamber. The higher-pressure gas flows from the pressure regulating chamber through the second flow channel, the third flow channel, the first flow channel, and the back pressure channel in sequence, and finally flows into the back pressure chamber, thereby providing a larger axial sealing force for the stationary plate assembly, realizing the axial seal between the stationary plate assembly and the moving plate, and preventing leakage.

[0020] When the compressor operates under mild conditions, a smaller axial sealing force is required. A lower pressure is regulated by the pressure regulating chamber. The lower-pressure gas flows from the pressure regulating chamber through the second flow channel, the third flow channel, the first flow channel, and the back pressure channel in sequence, and finally flows into the back pressure chamber. This provides a smaller axial sealing force for the stationary plate assembly, achieving axial sealing between the stationary plate assembly and the moving plate while avoiding excessive axial sealing force. This effectively reduces additional frictional power consumption and helps improve the overall energy efficiency of the compressor.

[0021] In some technical solutions, optionally, the flow area of ​​the third flow channel is smaller than the flow area of ​​the first flow channel; and / or the flow area of ​​the first flow channel is smaller than the flow area of ​​the back pressure channel.

[0022] In this technical solution, when the corresponding gas pressure is introduced into the back pressure chamber according to the compressor's operating conditions, the flow resistance of the gas can be reduced, and the optimized back pressure can be quickly introduced, which is beneficial to improving the compressor's energy efficiency.

[0023] In some technical solutions, optionally, the flow guiding component is disposed inside the housing; and / or the second connector is connected to the housing.

[0024] In this technical solution, since the flow guiding component is located inside the housing, it not only introduces the pressure from the pressure regulating chamber to the back pressure chamber to regulate the pressure in the back pressure chamber, but also facilitates the connection and fixation between the flow guiding component and the stationary plate component, which helps to improve the overall reliability of the compressor.

[0025] Since the second connector is connected to the housing, the overall installation stability and reliability of the flow guiding assembly can be improved. While enabling high-pressure or low-pressure gas to be introduced into the back pressure chamber, leakage caused by damage to the flow guiding assembly is prevented, which helps to ensure the overall energy efficiency of the compressor.

[0026] In some technical solutions, optionally, the first connector is provided with a first floating groove, the first floating groove is connected to the first flow channel, the first end of the guide tube is inserted into the first floating groove and can move along the axial direction of the moving disk in the first floating groove; and / or the second connector is provided with a second floating groove, the second floating groove is connected to the second flow channel, the second end of the guide tube is inserted into the second floating groove and can move along the axial direction of the moving disk in the second floating groove.

[0027] In this technical solution, when the stationary disc assembly has a slight axial movement relative to the moving disc, the guide pipe is floatingly connected to the first connector and / or the second connector, ensuring that the guide pipe and the first connector, and / or the guide pipe and the second connector, remain sealed at all times, preventing gas leakage and thus ensuring the overall energy efficiency of the compressor. Furthermore, it facilitates the assembly of the guide pipe assembly, improving the overall assembly efficiency of the compressor.

[0028] In some technical solutions, the flow guiding assembly may optionally include a seal, which is disposed between the first end of the flow guiding tube and the wall of the first floating groove, and / or the seal is disposed between the second end of the flow guiding tube and the wall of the second floating groove.

[0029] In this technical solution, by setting a sealing element, it is beneficial to improve the sealing performance between the first connector and the guide pipe, and / or between the second connector and the guide pipe, thereby reducing gas leakage while realizing the introduction of pressure into the back pressure chamber.

[0030] In some technical solutions, optionally, the pressure regulating chamber includes a chamber body and a connecting pipe, wherein one end of the connecting pipe is connected to the chamber body, the other end of the connecting pipe is connected to the flow guiding assembly, and the chamber body is connected to the flow guiding channel through the connecting pipe.

[0031] Specifically, in this technical solution, when the compressor is operating under harsh conditions, a larger axial sealing force is required. A higher pressure is adjusted through the pressure regulating chamber. The higher-pressure gas flows from the chamber body through the connecting pipe, the guide channel, and the back pressure channel in sequence, and finally flows into the back pressure chamber, thereby providing a larger axial sealing force for the stationary plate assembly, realizing the axial seal between the stationary plate assembly and the moving plate, and preventing leakage.

[0032] When the compressor operates under mild conditions, a smaller axial sealing force is required. A lower pressure is regulated by the pressure regulating chamber. The lower-pressure gas flows from the chamber body through the connecting pipe, the guide channel, and the back pressure channel in sequence, and finally flows into the back pressure chamber. This provides a smaller axial sealing force for the stationary plate assembly, achieving axial sealing between the stationary plate assembly and the moving plate while avoiding excessive axial sealing force. This effectively reduces additional frictional power consumption and helps improve the overall energy efficiency of the compressor.

[0033] In some technical solutions, the back pressure channel may optionally include a first channel and a second channel, wherein at least a portion of the first channel extends radially along the moving disk and one end of the first channel is connected to the guide channel, and at least a portion of the second channel extends axially along the moving disk, one end of the second channel is connected to the other end of the first channel, and the other end of the second channel is connected to the back pressure chamber.

[0034] In this technical solution, the first channel is connected to the second connecting channel and the guide channel at both ends, and the second channel is connected to the back pressure chamber. That is, when gas of a corresponding pressure is introduced into the back pressure chamber, the gas flows from the pressure regulating chamber, sequentially through the guide channel, the first channel, and the second channel, and finally into the back pressure chamber. Since the pressure in the pressure regulating chamber is adjustable, the pressure in the pressure regulating chamber can be adjusted according to the actual operating conditions of the compressor, thereby adjusting the pressure in the back pressure chamber. This means that a suitable back pressure is matched for each operating condition of the compressor, thus optimizing the axial sealing force, preventing leakage, and reducing ineffective frictional work.

[0035] In some technical solutions, optionally, the flow area of ​​the first channel and the flow area of ​​the second channel are larger than the flow area of ​​the guide channel; and / or the flow area of ​​the first channel is smaller than the flow area of ​​the second channel.

[0036] In this technical solution, when the corresponding gas pressure is introduced into the back pressure chamber according to the compressor's operating conditions, the flow resistance of the gas can be reduced, and the optimized back pressure can be quickly introduced, which is beneficial to improving the compressor's energy efficiency.

[0037] In some technical solutions, optionally, the stationary disc assembly includes a stationary disc, a back pressure plate, and a float plate assembly. The stationary disc meshes with the moving disc, and the side of the stationary disc opposite to the moving disc is recessed to form a receiving portion. A first channel is provided in the stationary disc, with one end penetrating the outer side wall of the stationary disc. A flow guiding assembly is connected to the stationary disc. The back pressure plate is provided in the receiving portion, and the side of the back pressure plate opposite to the moving disc forms a recess with the receiving portion. A second channel is provided in the back pressure plate, and the float plate assembly is movably provided in the recess and surrounds the inner wall of the recess to form a back pressure cavity.

[0038] In this technical solution, since the pressure regulating chamber is connected to the back pressure chamber, and the pressure in the pressure regulating chamber is adjustable, the pressure in the pressure regulating chamber can be adjusted according to the actual operating conditions of the compressor, thereby adjusting the pressure in the back pressure chamber. This means that a suitable back pressure is matched for each operating condition of the compressor, thus optimizing the axial sealing force, preventing leakage, and reducing ineffective frictional work. Furthermore, it can reduce wear between the float assembly and the partition plate, ensuring a good seal between high and low pressure.

[0039] In some technical solutions, optionally, at least a portion of the pressure regulating chamber is located outside the housing.

[0040] In this technical solution, since at least part of the pressure regulating chamber is located on the outside of the housing, it is possible to optimize the axial sealing force while requiring less modification to the original structure of the compressor compared to placing the pressure regulating chamber inside the housing. This also avoids resulting in an excessively large overall housing volume that occupies too much space. Furthermore, it facilitates the adjustment of the pressure within the pressure regulating chamber, simplifying operation.

[0041] In some technical solutions, the gas in the pressure regulating chamber may optionally include refrigerant.

[0042] In this technical solution, since the gas in the pressure regulating chamber is refrigerant, the pressure in the pressure regulating chamber is adjusted by adjusting the refrigerant pressure in the pressure regulating chamber, thereby achieving adjustable pressure in the back pressure chamber. This optimizes the axial sealing force, and even if there is partial leakage between the guide channel and the back pressure channel, or within the guide channel, it will not affect the overall operation of the compressor, which is beneficial to improving the operating stability and reliability of the compressor.

[0043] In some technical solutions, optionally, the moving plate and stationary plate assembly form a compression chamber, and the compressor also includes a partition plate, which is disposed inside the housing and divides the housing into an intake chamber and an exhaust chamber. The compression structure is disposed inside the intake chamber, and the compression chamber can communicate with the exhaust chamber.

[0044] In this technical solution, since the compression structure is located in the intake chamber, the compressor is a low-pressure scroll compressor.

[0045] According to a second aspect of this utility model, a refrigeration device is provided, including a compressor as provided in any of the above technical solutions, and thus possesses all the beneficial technical effects of the compressor, which will not be repeated here.

Detailed Implementation

[0053] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0054] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0055] The following reference Figures 1 to 3 The present invention will be described in the form of a compressor 1 and a refrigeration device according to some embodiments thereof.

[0056] In one embodiment according to this application, such as Figure 1 , Figure 2 and Figure 3 As shown, a compressor 1 is proposed. The compressor 1 includes: a housing 10; a compression structure 20 disposed within the housing 10, the compression structure 20 including: a moving plate 22; a stationary plate assembly 24 meshing with the moving plate 22, the stationary plate assembly 24 having a back pressure chamber 243 on the side opposite to the moving plate 22; and a pressure regulating mechanism 30 for regulating the pressure of the back pressure chamber 243. The pressure regulating mechanism 30 includes a pressure regulating chamber 31 communicating with the back pressure chamber 243, wherein the pressure in the pressure regulating chamber 31 is adjustable.

[0057] The compressor 1 provided in this embodiment includes a housing 10, a compression structure 20, and a pressure regulating mechanism 30. Specifically, a stationary disc assembly 24 and a moving disc 22 mesh with each other. Optionally, the stationary disc assembly 24 and the moving disc 22 form a compression chamber 26. During the operation of the compressor 1, the moving disc 22 can rotate relative to the stationary disc assembly 24 to compress the refrigerant in the compression chamber 26. When the refrigerant pressure in the compression chamber 26 reaches the discharge pressure, the compressed high-temperature and high-pressure refrigerant is discharged from the discharge port of the stationary disc assembly 24, thus realizing the compression and discharge process.

[0058] The stationary disc assembly 24 has a back pressure chamber 243 on the side away from the moving disc 22. It can be understood that the pressure in the back pressure chamber 243 is generally the intermediate pressure, that is, the pressure in the back pressure chamber 243 is greater than the intake pressure and less than the exhaust pressure, thereby providing axial force to the stationary disc assembly 24 in the axial direction.

[0059] In related technologies, flow passages are typically provided on the fixed scroll end plate to transfer the pressure from the compression chamber to the intermediate pressure chamber. The pressure in the intermediate pressure chamber is calculated as the suction pressure multiplied by a coefficient, which is primarily related to the refrigerant's polytropic index and the position of the flow passages. Because the compressor's operating range needs to be considered, this coefficient is generally set relatively large. This results in the intermediate pressure chamber pressure exceeding the actual required pressure at the compressor's rated point, leading to an excessively high axial sealing force and additional frictional power consumption.

[0060] The pressure regulating mechanism 30 is used to regulate the pressure of the back pressure chamber 243. Specifically, the pressure regulating chamber 31 is connected to the back pressure chamber 243. That is to say, the method of drawing pressure from the compression chamber 26 to the intermediate pressure chamber in related technologies has been changed, and pressure is drawn from the pressure regulating chamber 31 to the back pressure chamber 243. Since the pressure in the pressure regulating chamber 31 is adjustable, the pressure in the pressure regulating chamber 31 can be adjusted according to the actual operating conditions of the compressor 1, thereby adjusting the pressure in the back pressure chamber 243. That is, a suitable back pressure is matched for each operating condition of the compressor 1, thereby optimizing the axial sealing force, preventing leakage, and reducing ineffective friction work.

[0061] Specifically, when compressor 1 operates under harsh conditions, a larger axial sealing force is required. A higher pressure is regulated by pressure regulating chamber 31 and supplied to back pressure chamber 243 to achieve axial sealing between stationary disc assembly 24 and moving disc 22, preventing leakage. When compressor 1 operates under mild conditions, a smaller axial sealing force is required. A lower pressure is regulated by pressure regulating chamber 31 and supplied to back pressure chamber 243. This achieves axial sealing between stationary disc assembly 24 and moving disc 22 while avoiding excessive axial sealing force, effectively reducing additional frictional power consumption and improving the overall energy efficiency of compressor 1.

[0062] Optionally, the pressure regulating chamber 31 is provided with a connection port, through which gas of different pressures can be introduced into the pressure regulating chamber 31 to achieve adjustable pressure within the pressure regulating chamber 31.

[0063] Optionally, the gas in the pressure regulating chamber 31 can be a refrigerant or other gases, depending on actual needs.

[0064] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, optionally, the stationary disk assembly 24 further includes a back pressure channel 240, which is connected to the back pressure chamber 243. The pressure regulating mechanism 30 further includes a flow guiding assembly 32, one end of which is connected to the stationary disk assembly 24, and the other end of which is connected to the pressure regulating chamber 31. The flow guiding assembly 32 includes a flow guiding channel 320, and the two ends of the flow guiding channel 320 are respectively connected to the back pressure channel 240 and the pressure regulating chamber 31.

[0065] In this embodiment, the pressure regulating mechanism 30 is further defined as including a flow guiding component 32. Specifically, one end of the flow guiding component 32 is connected to the stationary plate component 24, and the other end is connected to the pressure regulating chamber 31.

[0066] The flow guiding assembly 32 includes a flow guiding channel 320, and the stationary plate assembly 24 also includes a back pressure channel 240. One end of the back pressure channel 240 is connected to the back pressure chamber 243, and the other end is connected to the flow guiding channel 320. The flow guiding channel 320 is connected to the pressure regulating chamber 31.

[0067] Specifically, when the compressor 1 is operating under harsh conditions, a larger axial sealing force is required. A higher pressure is adjusted by the pressure regulating chamber 31. The higher pressure gas flows from the pressure regulating chamber 31 through the guide channel 320 and the back pressure channel 240 in sequence, and finally flows into the back pressure chamber 243, thereby providing a larger axial sealing force for the stationary plate assembly 24, realizing the axial seal between the stationary plate assembly 24 and the moving plate 22, and preventing leakage.

[0068] When compressor 1 operates under mild conditions, a smaller axial sealing force is required. A lower pressure is regulated by the pressure regulating chamber 31. The lower-pressure gas flows from the pressure regulating chamber 31, through the guide channel 320 and the back pressure channel 240, and finally into the back pressure chamber 243. This provides a smaller axial sealing force for the stationary plate assembly 24, achieving axial sealing between the stationary plate assembly 24 and the moving plate 22 while avoiding excessive axial sealing force. This effectively reduces additional frictional power consumption and helps improve the overall energy efficiency of compressor 1.

[0069] In some embodiments, the flow area of ​​the flow channel 320 may be smaller than the flow area of ​​the back pressure channel 240.

[0070] In this embodiment, since the flow area of ​​the guide channel 320 is smaller than that of the back pressure channel 240, a suitable back pressure can be matched according to the actual operating conditions of the compressor 1, thereby optimizing the axial sealing force and reducing the flow resistance when introducing gas into the back pressure chamber 243. When the compressor 1 switches between different operating conditions, the matching back pressure can be quickly introduced, which is beneficial to improving the energy efficiency of the compressor 1.

[0071] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, optionally, the flow channel 320 includes a first flow channel 321, a second flow channel 322, and a third flow channel 323. The flow guiding assembly 32 also includes a first connector 324, a second connector 325, and a flow guiding pipe 326. The first connector 324 is connected to the stationary plate assembly 24. The first flow channel 321 is located at the first connector 324 and communicates with the back pressure channel 240. The second connector 325 is connected to the pressure regulating chamber 31. The second flow channel 322 is located at the second connector 325 and communicates with the pressure regulating chamber 31. The flow guiding pipe 326 is located between the first connector 324 and the second connector 325, and both ends of the flow guiding pipe 326 are connected to the first connector 324 and the second connector 325, respectively. The third flow channel 323 is located at the flow guiding pipe 326, and both ends of the third flow channel 323 are connected to the first flow channel 321 and the second flow channel 322, respectively.

[0072] In this embodiment, the flow guiding assembly 32 further includes a first connector 324, a second connector 325, and a flow guiding pipe 326. Specifically, the first connector 324 is connected to the stationary disc assembly 24. Optionally, the first connector 324 is sealed to the stationary disc assembly 24. Optionally, the compressor 1 further includes a sealing gasket, wherein the sealing gasket is disposed between the first connector 324 and the stationary disc assembly 24 to seal the gap between the first connector 324 and the stationary disc assembly 24.

[0073] The guide pipe 326 is disposed between the first connector 324 and the second connector 325, and the second connector 325 is connected to the pressure regulating chamber 31. The guide channel 320 includes a first flow channel 321, a second flow channel 322 and a third flow channel 323, wherein the first flow channel 321 is disposed in the first connector 324, the second flow channel 322 is disposed in the second connector 325, and the third flow channel 323 is disposed in the guide pipe 326.

[0074] Specifically, when the compressor 1 operates under harsh conditions, a larger axial sealing force is required. A higher pressure is adjusted by the pressure regulating chamber 31. The higher-pressure gas flows from the pressure regulating chamber 31 through the second flow channel 322, the third flow channel 323, the first flow channel 321 and the back pressure channel 240 in sequence, and finally flows into the back pressure chamber 243, thereby providing a larger axial sealing force for the stationary disc assembly 24, realizing the axial seal between the stationary disc assembly 24 and the moving disc 22, and preventing leakage.

[0075] When compressor 1 operates under mild conditions, a smaller axial sealing force is required. A lower pressure is regulated by the pressure regulating chamber 31. The lower-pressure gas flows from the pressure regulating chamber 31 through the second flow channel 322, the third flow channel 323, the first flow channel 321, and the back pressure channel 240 in sequence, and finally flows into the back pressure chamber 243. This provides a smaller axial sealing force for the stationary plate assembly 24, achieving axial sealing between the stationary plate assembly 24 and the moving plate 22 while avoiding excessive axial sealing force. This effectively reduces additional frictional power consumption and helps improve the overall energy efficiency of compressor 1.

[0076] In some embodiments, the flow area of ​​the third flow channel 323 may be smaller than the flow area of ​​the first flow channel 321; and / or the flow area of ​​the first flow channel 321 may be smaller than the flow area of ​​the back pressure channel 240.

[0077] In this embodiment, the flow area of ​​the third flow channel 323 is smaller than the flow area of ​​the first flow channel 321, or the flow area of ​​the first flow channel 321 is smaller than the flow area of ​​the back pressure channel 240, or the flow area of ​​the third flow channel 323 is smaller than the flow area of ​​the first flow channel 321, and the flow area of ​​the first flow channel 321 is smaller than the flow area of ​​the back pressure channel 240. That is to say, the flow area of ​​the third flow channel 323, the flow area of ​​the first flow channel 321, and the flow area of ​​the back pressure channel 240 increase sequentially.

[0078] When the corresponding gas pressure is introduced into the back pressure chamber 243 according to the operating conditions of the compressor 1, the flow resistance of the gas can be reduced, and the optimized back pressure can be quickly introduced, which is beneficial to improving the energy efficiency of the compressor 1.

[0079] In some embodiments, optionally, the flow guiding assembly 32 is disposed within the housing 10; and / or the second connector 325 is connected to the housing 10.

[0080] In this embodiment, since the flow guide assembly 32 is located inside the housing 10, it can guide the pressure of the pressure regulating chamber 31 to the back pressure chamber 243 to achieve pressure regulation of the back pressure chamber 243, while facilitating the connection and fixation between the flow guide assembly 32 and the stationary plate assembly 24, which is beneficial to improving the overall reliability of the compressor 1.

[0081] Since the second connector 325 is connected to the housing 10, the overall installation stability and reliability of the flow guiding assembly 32 can be improved. While enabling high-pressure gas or low-pressure gas to be introduced into the back pressure chamber 243, leakage caused by damage to the flow guiding assembly 32 is prevented, which helps to ensure the overall energy efficiency of the compressor 1.

[0082] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, optionally, the first connector 324 is provided with a first floating groove 327, which is connected to the first flow channel 321, and the first end of the guide tube 326 is inserted into the first floating groove 327 and can move along the axial direction of the moving disk 22 within the first floating groove 327; and / or the second connector 325 is provided with a second floating groove 328, which is connected to the second flow channel 322, and the second end of the guide tube 326 is inserted into the second floating groove 328 and can move along the axial direction of the moving disk 22 within the second floating groove 328.

[0083] In this embodiment, since the first connector 324 is provided with a first floating groove 327 and the first floating groove 327 is connected to the first flow channel 321, the first end of the guide pipe 326 is inserted into the first floating groove 327 and can move along the axial direction of the moving disk 22 in the first floating groove 327. That is to say, the guide pipe 326 is floatingly connected to the first connector 324.

[0084] Alternatively, the second connector 325 is provided with a second floating groove 328, and the second floating groove 328 is connected to the second flow channel 322. The second end of the guide pipe 326 is inserted into the second floating groove 328 and can move along the axial direction of the moving plate 22 within the second floating groove 328. In other words, the guide pipe 326 is floatingly connected to the second connector 325.

[0085] Alternatively, the first connector 324 may be provided with a first floating groove 327, and the second connector 325 may be provided with a second floating groove 328. That is, the two ends of the guide pipe 326 are respectively floatingly connected to the first connector 324 and the second connector 325. The specific configuration can be made according to actual needs.

[0086] When the stationary disc assembly 24 has a slight axial movement relative to the moving disc 22, the guide pipe 326 is floatingly connected to the first connector 324 and / or the second connector 325, ensuring that the guide pipe 326 and the first connector 324, and / or the guide pipe 326 and the second connector 325 remain sealed at all times, preventing gas leakage and helping to ensure the overall energy efficiency of the compressor 1. Furthermore, it facilitates the assembly of the guide pipe assembly 32, thus improving the overall assembly efficiency of the compressor 1.

[0087] like Figure 3 As shown, in some embodiments, optionally, the flow guiding assembly 32 further includes a seal 329, which is disposed between the first end of the flow guiding pipe 326 and the groove wall of the first floating groove 327, and / or the seal 329 is disposed between the second end of the flow guiding pipe 326 and the groove wall of the second floating groove 328.

[0088] In this embodiment, the flow guiding assembly 32 further includes a seal 329. Specifically, the seal 329 is disposed between the first end of the flow guiding tube 326 and the wall of the first floating groove 327. Alternatively, the seal 329 is disposed between the second end of the flow guiding tube 326 and the wall of the second floating groove 328. Alternatively, there are two seals 329, one of which is disposed between the first end of the flow guiding tube 326 and the wall of the first floating groove 327, and the other is disposed between the second end of the flow guiding tube 326 and the wall of the second floating groove 328.

[0089] By setting the seal 329, it is beneficial to improve the sealing between the first connector 324 and the guide tube 326, and / or between the second connector 325 and the guide tube 326, so as to reduce gas leakage while realizing the pressure introduction in the back pressure chamber 243.

[0090] Optionally, seal 329 includes a sealing ring.

[0091] Optionally, the outer wall of the first end of the guide tube 326 is provided with a first mounting groove. When the seal 329 is disposed between the first end of the guide tube 326 and the groove wall of the first floating groove 327, the seal 329 is located in the first mounting groove.

[0092] Optionally, the outer wall of the second end of the guide tube 326 is provided with a second mounting groove. When the seal 329 is disposed between the second end of the guide tube 326 and the groove wall of the second floating groove 328, the seal 329 is located in the second mounting groove.

[0093] like Figure 1 and Figure 2 As shown, in some embodiments, optionally, the pressure regulating chamber 31 includes a chamber body 312 and a connecting pipe 314, wherein one end of the connecting pipe 314 is connected to the chamber body 312, and the other end of the connecting pipe 314 is connected to the flow guiding assembly 32, and the chamber body 312 is connected to the flow guiding channel 320 through the connecting pipe 314.

[0094] In this embodiment, the pressure regulating chamber 31 is defined as including a chamber body 312 and a connecting pipe 314. Specifically, the two ends of the connecting pipe 314 are respectively connected to the chamber body 312 and the flow channel 320.

[0095] Specifically, when the compressor 1 is operating under harsh conditions, a larger axial sealing force is required. A higher pressure is adjusted by the pressure regulating chamber 31. The higher pressure gas flows from the chamber body 312 through the connecting pipe 314, the guide channel 320 and the back pressure channel 240 in sequence, and finally flows into the back pressure chamber 243, thereby providing a larger axial sealing force for the stationary disc assembly 24, realizing the axial seal between the stationary disc assembly 24 and the moving disc 22, and preventing leakage.

[0096] When compressor 1 operates under mild conditions, a smaller axial sealing force is required. A lower pressure is regulated by the pressure regulating chamber 31. The lower-pressure gas flows from the chamber body 312 through the connecting pipe 314, the guide channel 320, and the back pressure channel 240 in sequence, and finally flows into the back pressure chamber 243. This provides a smaller axial sealing force for the stationary disc assembly 24, achieving axial sealing between the stationary disc assembly 24 and the moving disc 22 while avoiding excessive axial sealing force. This effectively reduces additional frictional power consumption and helps improve the overall energy efficiency of compressor 1.

[0097] Optionally, the connecting pipe 314 and the chamber body 312 are an integral structure, which can reduce gas leakage.

[0098] like Figure 1 , Figure 2 and Figure 3As shown, in some embodiments, optionally, the back pressure channel 240 includes a first channel 241 and a second channel 242, wherein at least a portion of the first channel 241 extends radially along the moving disk 22, one end of the first channel 241 is connected to the guide channel 320, at least a portion of the second channel 242 extends axially along the moving disk 22, one end of the second channel 242 is connected to the other end of the first channel 241, and the other end of the second channel 242 is connected to the back pressure cavity 243.

[0099] In this embodiment, the back pressure channel 240 is defined as including a first channel 241 and a second channel 242. Specifically, at least a portion of the first channel 241 extends radially and at least a portion of the second channel 242 extends axially.

[0100] Since the two ends of the first channel 241 are connected to the second channel and the guide channel 320 respectively, and the second channel 242 is connected to the back pressure chamber 243, when gas of the corresponding pressure is introduced into the back pressure chamber 243, the gas flows from the pressure regulating chamber 31, through the guide channel 320, the first channel 241 and the second channel 242 in sequence, and finally into the back pressure chamber 243. Because the pressure in the pressure regulating chamber 31 is adjustable, the pressure in the pressure regulating chamber 31 can be adjusted according to the actual operating conditions of the compressor 1, thereby adjusting the pressure in the back pressure chamber 243. That is, a suitable back pressure is matched for each operating condition of the compressor 1, thereby optimizing the axial sealing force, preventing leakage while reducing ineffective frictional work.

[0101] In some embodiments, the flow area of ​​the first channel 241 and the flow area of ​​the second channel 242 are respectively greater than the flow area of ​​the guide channel 320; and / or the flow area of ​​the first channel 241 is less than the flow area of ​​the second channel 242.

[0102] In this embodiment, specifically, the flow area of ​​the first channel 241 is larger than the flow area of ​​the guide channel 320, and the flow area of ​​the second channel 242 is also larger than the flow area of ​​the guide channel 320. Alternatively, the flow area of ​​the first channel 241 is smaller than the flow area of ​​the second channel 242. Alternatively, the flow areas of the guide channel 320, the first channel 241, and the second channel 242 increase sequentially.

[0103] When the corresponding gas pressure is introduced into the back pressure chamber 243 according to the operating conditions of the compressor 1, the flow resistance of the gas can be reduced, and the optimized back pressure can be quickly introduced, which is beneficial to improving the energy efficiency of the compressor 1.

[0104] like Figure 1 , Figure 2 and Figure 3As shown, in some embodiments, optionally, the stationary disk assembly 24 includes a stationary disk 244, a back pressure plate 245, and a float assembly 247. The stationary disk 244 meshes with the moving disk 22. The side of the stationary disk 244 opposite to the moving disk 22 is recessed to form a receiving portion 248. A first channel 241 is provided in the stationary disk 244, with one end penetrating the outer side wall of the stationary disk 244. A flow guide assembly 32 is connected to the stationary disk 244. The back pressure plate 245 is provided in the receiving portion 248. The side of the back pressure plate 245 opposite to the moving disk 22 forms a recess 246 with the receiving portion 248. A second channel 242 is provided in the back pressure plate 245. The float assembly 247 is movably provided in the recess 246 and surrounds the inner wall of the recess 246 to form a back pressure cavity 243.

[0105] In this embodiment, the stationary disk assembly 24 is defined to include a stationary disk 244, a back pressure plate 245, and a float assembly 247. Specifically, the stationary disk 244 meshes with the moving disk 22. Optionally, the stationary disk 244 and the moving disk 22 form a compression chamber 26. The stationary disk 244 is provided with an exhaust port. Specifically, during the operation of the compressor 1, the moving disk 22 can rotate relative to the stationary disk 244 to compress the refrigerant in the compression chamber 26. When the refrigerant pressure in the compression chamber 26 reaches the exhaust pressure, the compressed high-temperature and high-pressure refrigerant is discharged from the exhaust port, realizing the compression and exhaust process.

[0106] The back pressure plate 245 and the stationary disc 244 form a recess 246, and the inner wall of the recess 246 and the float assembly 247 enclose a back pressure cavity 243. Specifically, when the compressor 1 is running, the float assembly 247 moves away from the moving disc 22 until it abuts against the partition plate 40. The float assembly 247 and the inner wall of the recess 246 form the back pressure cavity 243, thereby providing back pressure to the stationary disc 244 in the axial direction, ensuring an axial seal between the stationary disc 244 and the moving disc 22, and preventing leakage. Since the float assembly 247 abuts against the partition plate 40, a seal between the high and low pressures can be achieved. When the compressor 1 stops running, the float assembly 247 moves towards the moving disc 22 and separates from the partition plate 40, allowing communication between the high and low pressures.

[0107] Since the pressure regulating chamber 31 is connected to the back pressure chamber 243, and the pressure in the pressure regulating chamber 31 is adjustable, the pressure in the pressure regulating chamber 31 can be adjusted according to the actual operating conditions of the compressor 1, thereby adjusting the pressure in the back pressure chamber 243. This means that a suitable back pressure can be matched for each operating condition of the compressor 1, thus optimizing the axial sealing force, preventing leakage, and reducing ineffective frictional work. Furthermore, it can reduce wear between the float assembly 247 and the partition plate 40, ensuring a good sealing effect between high and low pressure.

[0108] like Figure 1 and Figure 2As shown, in some embodiments, optionally, at least a portion of the pressure regulating chamber 31 is located outside the housing 10.

[0109] In this embodiment, since at least part of the pressure regulating chamber 31 is located on the outside of the housing 10, it is possible to optimize the axial sealing force while requiring less modification to the original structure of the compressor 1 compared to placing the pressure regulating chamber 31 inside the housing 10. This also avoids making the overall volume of the housing 10 too large and occupying too much space. Furthermore, it facilitates the adjustment of the pressure within the pressure regulating chamber 31, making operation easier.

[0110] Optionally, the housing 10 is provided with a clearance opening, and a portion of the second connector 325 extends out of the housing 10 through the clearance opening. The connecting pipe 314 is connected to the portion of the second connector 325 that extends out of the housing 10.

[0111] In some embodiments, the gas in the pressure regulating chamber 31 may optionally include a refrigerant.

[0112] In this embodiment, since the gas in the pressure regulating chamber 31 is a refrigerant, the pressure in the pressure regulating chamber 31 can be adjusted by adjusting the refrigerant pressure in the pressure regulating chamber 31, thereby achieving adjustable pressure in the back pressure chamber 243. This optimizes the axial sealing force, and even if there is partial leakage between the flow channel 320 and the back pressure channel 240, or within the flow channel 320, it will not affect the overall operation of the compressor 1, which is beneficial to improving the operational stability and reliability of the compressor 1.

[0113] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, optionally, the moving disc 22 and the stationary disc assembly 24 form a compression chamber 26. The compressor 1 also includes a partition plate 40, which is disposed inside the housing 10 and divides the housing 10 into an intake chamber 12 and an exhaust chamber 14. The compression structure 20 is disposed inside the intake chamber 12, and the compression chamber 26 can communicate with the exhaust chamber 14.

[0114] In this embodiment, the compressor 1 further includes a partition plate 40. Specifically, the partition plate 40 divides the housing 10 into an intake chamber 12 and an exhaust chamber 14. The compression structure 20 is disposed within the intake chamber 12, and the compression chamber 26 is connected to the exhaust chamber 14. Specifically, during the operation of the compressor 1, the moving disc 22 can rotate relative to the stationary disc assembly 24 to compress the refrigerant in the compression chamber 26. When the refrigerant pressure in the compression chamber 26 reaches the exhaust pressure, the compressed high-temperature and high-pressure refrigerant is discharged from the exhaust port of the stationary disc assembly 24 into the exhaust chamber 14, and then discharged outside the housing 10, thus realizing the compression and exhaust process. That is to say, the intake chamber 12 is a low-pressure chamber, and the exhaust chamber 14 is a high-pressure chamber.

[0115] Since the compression structure 20 is located inside the intake chamber 12, the compressor 1 is a low-pressure scroll compressor.

[0116] In one specific embodiment, the compressor 1 includes a housing 10, an exhaust chamber (exhaust chamber 14), an intake chamber (intake chamber 12), a back pressure plate assembly, a moving scroll component (moving disk 22), a fixed scroll component (stationary disk 244), and a float assembly 247. The housing 10 defines an intake pressure zone and an exhaust pressure zone. The exhaust chamber where the exhaust passage is located is the exhaust pressure zone, and the intake chamber where the intake passage is located is the intake pressure zone.

[0117] The back pressure plate assembly includes a back pressure plate 245 and a sealing gasket. The moving scroll component (moving disk 22) includes a moving scroll end plate and helical moving scroll blades formed on one side of the moving scroll end plate. The stationary scroll component (stationary disk 244) includes a stationary scroll end plate and helical stationary scroll blades formed on one side of the stationary scroll end plate. The stationary scroll component and the back pressure plate assembly may form a recess 246. The float assembly 247 mates with the recess 246 formed by the stationary scroll component and the back pressure plate assembly to jointly form a back pressure cavity 243, which is the intermediate pressure zone.

[0118] The stationary vortex component (stationary disc 244) has a rotary joint (first joint 324), a bypass pipe (guide pipe 326), and a housing adapter (second joint 325) mounted on its side. A gas-guiding channel (back pressure channel 240) is machined on the stationary vortex component (stationary disc 244), which communicates with the intermediate pressure chamber (back pressure chamber 243). The adapter (second joint 325) is mounted on the housing (shell 10), connecting the housing (shell 10) and the stationary vortex component (stationary disc 244) via a bypass pipe (guide pipe 326). A pressure control mechanism (pressure regulating mechanism 30) is installed outside the housing and communicates with the adapter (second joint 325) on the housing, enabling control of the pressure in the intermediate pressure chamber. When the vortex operates under conditions requiring high sealing force at the tooth tip, tooth root, and float plate, the vortex requires higher axial force. The pressure in the gas chamber can be increased to raise the pressure in the intermediate pressure chamber. When the scroll plate operates in a region where the sealing force requirements of the tooth tip, tooth root, and float plate are low, the scroll plate requires a smaller axial force to reduce the pressure in the air chamber, thereby reducing the pressure in the intermediate pressure chamber. This ensures that there is an optimal intermediate pressure chamber pressure for each operating condition, thus achieving sealing and reducing ineffective frictional work.

[0119] By adjusting the pressure of the intermediate pressure chamber (back pressure chamber 243), the optimal intermediate chamber pressure can be achieved under different operating conditions, so that the compressor 1 can operate with the optimal axial force at each operating point, achieving the optimal sealing effect of the top and bottom of the scroll teeth and the float (float assembly 247), and reducing ineffective frictional power consumption.

[0120] According to a second aspect of the present invention, a refrigeration device is provided, including a compressor 1 as provided in any of the above embodiments, and thus possesses all the beneficial technical effects of the compressor 1, which will not be repeated here.

[0121] Alternatively, the refrigeration equipment may include air conditioners, refrigerators, or freezers.

[0122] Optionally, the compressor 1 includes a housing 10, a compression structure 20, and a pressure regulating mechanism 30. Specifically, the stationary disk assembly 24 and the moving disk 22 mesh with each other. Optionally, the stationary disk assembly 24 and the moving disk 22 form a compression chamber 26. During the operation of the compressor 1, the moving disk 22 can rotate relative to the stationary disk assembly 24 to compress the refrigerant in the compression chamber 26. When the refrigerant pressure in the compression chamber 26 reaches the discharge pressure, the compressed high-temperature and high-pressure refrigerant is discharged from the discharge port of the stationary disk assembly 24, thus realizing the compression and discharge process.

[0123] The stationary disc assembly 24 has a back pressure chamber 243 on the side away from the moving disc 22. It can be understood that the pressure in the back pressure chamber 243 is generally the intermediate pressure, that is, the pressure in the back pressure chamber 243 is greater than the intake pressure and less than the exhaust pressure, thereby providing axial force to the stationary disc assembly 24 in the axial direction.

[0124] In related technologies, flow passages are typically provided on the fixed scroll end plate to transfer the pressure from the compression chamber to the intermediate pressure chamber. The pressure in the intermediate pressure chamber is calculated as the suction pressure multiplied by a coefficient, which is primarily related to the refrigerant's polytropic index and the position of the flow passages. Because the compressor's operating range needs to be considered, this coefficient is generally set relatively large. This results in the intermediate pressure chamber pressure exceeding the actual required pressure at the compressor's rated point, leading to an excessively high axial sealing force and additional frictional power consumption.

[0125] The pressure regulating chamber 31 is connected to the back pressure chamber 243. This means that the method of drawing pressure from the compression chamber 26 to the intermediate pressure chamber in related technologies has been changed; instead, pressure is drawn from the pressure regulating chamber 31 to the back pressure chamber 243. Since the pressure in the pressure regulating chamber 31 is adjustable, the pressure in the pressure regulating chamber 31 can be adjusted according to the actual operating conditions of the compressor 1, thereby adjusting the pressure in the back pressure chamber 243. This allows for matching a suitable back pressure for each operating condition of the compressor 1, thus optimizing the axial sealing force, preventing leakage, and reducing ineffective frictional work.

[0126] Specifically, when compressor 1 operates under harsh conditions, a larger axial sealing force is required. A higher pressure is regulated by pressure regulating chamber 31 and supplied to back pressure chamber 243 to achieve axial sealing between stationary disc assembly 24 and moving disc 22, preventing leakage. When compressor 1 operates under mild conditions, a smaller axial sealing force is required. A lower pressure is regulated by pressure regulating chamber 31 and supplied to back pressure chamber 243. This achieves axial sealing between stationary disc assembly 24 and moving disc 22 while avoiding excessive axial sealing force, effectively reducing additional frictional power consumption and improving the overall energy efficiency of compressor 1.
