Description

Technical Field

[0001] The present invention relates to the field of compressor technology, and in particular to a scroll compressor and an air conditioning system. Background Technology

[0002] Currently, when air source heat pumps are used in cold regions during winter, a single-unit enthalpy-increasing scroll compressor or a single-unit two-stage scroll compressor is typically selected.

[0003] Existing single-unit enthalpy-increasing scroll compressors suffer from a sharp drop in energy efficiency when operating at low ambient temperatures, particularly below -12°C, due to the influence of the gas injection method. Furthermore, at -25°C, the unit cannot operate due to the excessively high compression ratio. In contrast, a single-unit two-stage scroll compressor, with its two-stage compression structure, can share the high and low pressure ratios, allowing for a larger design pressure ratio. It offers a large gas injection volume and a large injection chamber, resulting in strong resistance to liquid slugging. This allows the single-unit two-stage scroll compressor to operate normally at ultra-low ambient temperatures. Simultaneously, its large gas injection volume ensures efficient operation even at low ambient temperatures, thus solving the problems of significant energy loss and poor efficiency in low-temperature heating performance associated with traditional single-unit enthalpy-increasing scroll compressors.

[0004] However, due to the large design pressure ratio of the single-unit two-stage scroll compressor, the actual working pressure ratio of the compressor is lower than the design pressure ratio under high ambient temperature refrigeration conditions. This results in the compressor output pressure being greater than the required pressure, causing some of the work done by the compressor to be wasted and reducing energy efficiency. Under high ambient temperature refrigeration conditions, the single-unit two-stage scroll compressor has a significant energy efficiency disadvantage compared to the single-unit gas-injection enthalpy-increasing scroll compressor. Summary of the Invention

[0005] This invention provides a scroll compressor and an air conditioning system to solve the problem that existing single-unit scroll compressors cannot simultaneously achieve high-efficiency heating under low ambient temperature heating conditions and high-efficiency cooling under high ambient temperature cooling conditions.

[0006] To solve the above-mentioned technical problems, the present invention provides a scroll compressor, which includes: a fixed disk, an electromagnetic coil, a clutch slider, a stationary scroll disk, a moving scroll disk, and an adjusting scroll disk;

[0007] The stationary vortex disk is fixedly connected to the fixed disk; the moving vortex disk can rotate relative to the stationary vortex disk.

[0008] The adjusting scroll plate is disposed between the fixed plate and the moving scroll plate, and the clutch slider passes through the adjusting scroll plate;

[0009] The electromagnetic coil is fixedly connected to the fixed disk, and the clutch slider is provided with a magnet. The electromagnetic coil is used to drive the clutch slider to engage with the moving scroll plate, or to drive the clutch slider to engage with the fixed disk.

[0010] When the clutch slider is engaged with the moving scroll plate, the moving scroll plate rotates synchronously with the adjusting scroll plate;

[0011] When the clutch slider is engaged with the fixed disk, the moving scroll plate rotates relative to the adjusting scroll plate.

[0012] Optionally, the clutch slider has an annular columnar structure, and the annular columnar structure is coaxially arranged with the electromagnetic coil;

[0013] The adjusting vortex disk is provided with a first through hole along the circumference, and the annular columnar structure is provided with a first protrusion structure along the axial direction, the first protrusion structure passing through the first through hole.

[0014] Optionally, the moving scroll disk is provided with a first groove structure;

[0015] When the clutch slider is engaged with the moving scroll plate, the first groove structure and the first protrusion structure are in a concave-convex fit.

[0016] Optionally, the fixed disk is provided with a second protrusion structure, and the clutch slider is provided with a second groove structure;

[0017] When the clutch slider is engaged with the fixed disc, the second groove structure and the second protrusion structure are in a concave-convex fit.

[0018] Optionally, the inner wall of the fixed disk is provided with a third groove structure along the circumference, and the electromagnetic coil is embedded in the third groove structure, wherein the inner wall of the fixed disk is the cavity surface on which the adjusting scroll plate is provided.

[0019] Optionally, the fixed disk is provided with a second through hole in the circumferential direction; the fixed disk is provided with a third through hole in the axial direction.

[0020] Optionally, the scroll compressor further includes: a one-way valve;

[0021] The one-way valve is located at the third through hole and is fixedly connected to the fixed plate; the one-way valve is used to discharge compressed air.

[0022] Optionally, the scroll compressor further includes: a motor;

[0023] The output shaft of the motor is fixedly connected to the moving scroll plate.

[0024] Optionally, the scroll compressor further includes: bearings;

[0025] The inner ring of the bearing is fixedly connected to the output shaft of the motor, and the outer ring of the bearing is fixedly connected to the stationary scroll plate.

[0026] This invention also provides an air conditioning system, which includes the scroll compressor described in any of the preceding embodiments.

[0027] This invention provides a scroll compressor and air conditioning system. Because the electromagnetic coil can drive the clutch slider to engage with the moving scroll, there is no relative rotation between the adjusting scroll and the moving scroll. When the moving scroll rotates, the adjusting scroll rotates synchronously with it. At this time, the first compression section formed between the moving and stationary scrolls compresses the refrigerant. The scroll compressor is a single-stage compressor, which can meet the usage requirements under high ambient temperature cooling conditions while ensuring high energy efficiency. The electromagnetic coil can also drive the clutch slider to engage with the fixed plate, ensuring no relative rotation between the adjusting scroll and the fixed plate. When the moving scroll rotates... The moving scroll can rotate relative to the adjusting scroll. At this time, while the first compression section formed between the moving scroll and the stationary scroll compresses the refrigerant, the second compression section formed between the moving scroll and the adjusting scroll can also compress the refrigerant. This allows the refrigerant compressed by the first compression section to enter the second compression section for further compression. The scroll compressor is a two-stage compressor, which can meet the usage requirements under low ambient temperature heating conditions while ensuring high energy efficiency. Thus, a single scroll compressor can achieve the advantages of high-efficiency heating under low ambient temperature heating conditions and high-efficiency cooling under high ambient temperature cooling conditions.

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] This invention provides a scroll compressor, comprising: a fixed disk 10, an electromagnetic coil 20, a clutch slider 30, a stationary scroll 40, a moving scroll 50, and an adjusting scroll 60; the stationary scroll 40 is fixedly connected to the fixed disk 10; the moving scroll 50 is rotatable relative to the stationary scroll 40; the adjusting scroll 60 is disposed between the fixed disk 10 and the moving scroll 50, and the clutch slider 30 passes through the adjusting scroll 60; the electromagnetic coil 20 and the fixed disk 10 are connected to the fixed disk 10. The fixed disk 10 is fixedly connected, the clutch slider 30 is provided with a magnet, and the electromagnetic coil 20 is used to drive the clutch slider 30 to engage with the moving scroll plate 50, or to drive the clutch slider 30 to engage with the fixed disk 10; when the clutch slider 30 is engaged with the moving scroll plate 50, the moving scroll plate 50 and the adjusting scroll plate 60 rotate synchronously; when the clutch slider 30 is engaged with the fixed disk 10, the moving scroll plate 50 and the adjusting scroll plate 60 rotate relative to each other.

[0039] See Figure 1 and Figure 3A first compression section is formed between the moving scroll 50 and the stationary scroll 40. The refrigerant can enter the first compression section through the intake pipe 11 of the scroll compressor. The moving scroll 50 can rotate relative to the stationary scroll 40, causing the cavity volume of the first compression section to change. The refrigerant entering the cavity is compressed and discharged into the channel provided in the scroll compressor cylinder, thus completing the first stage of compression.

[0040] The adjusting scroll plate 60 is positioned between the moving scroll plate 50 and the fixed plate 10. The moving scroll plate 50 and the fixed plate 10 can constrain the movement of the adjusting scroll plate 60 along the rotation axis of the moving scroll plate 50. In practical applications, an elastic element can be provided at the contact position between the adjusting scroll plate 60 and the moving scroll plate 50 to ensure the sealing performance of the cavity formed by the adjusting scroll plate 60 and the moving scroll plate 50.

[0041] Under high ambient temperature refrigeration conditions, the electromagnetic coil 20 can control the change of magnetic poles through current, repelling the clutch slider 30 and causing the clutch slider 30 to engage with the moving scroll plate 50. Since the clutch slider 30 passes through the adjusting scroll plate 60 and is engaged with the moving scroll plate 50, the adjusting scroll plate 60 can be constrained, so that the adjusting scroll plate 60 and the moving scroll plate 50 do not rotate relative to each other. When the moving scroll plate 50 rotates, the clutch slider 30 can drive the adjusting scroll plate 60 to rotate synchronously, that is, the adjusting scroll plate 60 and the moving scroll plate 50 form a whole. At this time, the first compression section formed between the moving scroll plate 50 and the stationary scroll plate 40 compresses the refrigerant to do work, and the scroll compressor is a single-stage compression.

[0042] Under low ambient temperature heating conditions, the electromagnetic coil 20 can control the change of magnetic poles through current, attracting the clutch slider 30 and causing the clutch slider 30 to engage with the fixed disk 10. Since the clutch slider 30 passes through the adjusting scroll plate 60 and is engaged with the fixed disk 10, the adjusting scroll plate 60 can be constrained, so that the adjusting scroll plate 60 and the fixed disk 10 do not rotate relative to each other. When the moving scroll plate 50 rotates, the moving scroll plate 50 and the adjusting scroll plate 60 rotate relative to each other. At this time, the cavity volume of the second compression section formed between the moving scroll plate 50 and the adjusting scroll plate 60 changes, which can compress the refrigerant entering the cavity, so that the refrigerant compressed by the first compression section can enter the second compression section to be further compressed, realizing the two-stage compression of the refrigerant.

[0043] The scroll compressor provided in this invention can perform two-stage compression during low ambient temperature heating, providing a large injection volume and meeting high energy efficiency requirements. Tests have shown that its heating COP (Coefficient of Performance) can reach 3.6 at 7°C and 2.85 at -12°C, which is superior to the COP of a single-unit two-stage scroll compressor under the same conditions. Furthermore, it can achieve stable heating at -35°C. Simultaneously, under high ambient temperature cooling conditions, the COP can reach 3.1, achieving a balance between high-efficiency heating at low ambient temperatures and high-efficiency cooling at high ambient temperatures.

[0044] See Figure 2 The fixed disk 10 may be provided with a circular vent hole. The refrigerant that has undergone primary compression enters the second compression section composed of the moving scroll disk 50 and the adjusting scroll disk 60 through the circular vent hole. The refrigerant that has undergone secondary compression in the second compression section can be discharged from the compressor through the exhaust hole of the fixed disk 10 and the exhaust pipe 12 of the scroll compressor in sequence, thus completing the compression cycle of the system.

[0045] This invention provides a scroll compressor in which the electromagnetic coil 20 can drive the clutch slider 30 to engage with the moving scroll plate 50, preventing relative rotation between the adjusting scroll plate 60 and the moving scroll plate 50. When the moving scroll plate 50 rotates, the adjusting scroll plate 60 rotates synchronously with it. At this time, the first compression section formed between the moving scroll plate 50 and the stationary scroll plate 40 compresses the refrigerant. This scroll compressor is a single-stage compressor, capable of meeting usage requirements under high ambient temperature refrigeration conditions while ensuring high energy efficiency. The electromagnetic coil 20 can also drive the clutch slider 30 to engage with the fixed plate 10, preventing relative rotation between the adjusting scroll plate 60 and the fixed plate 10. When the scroll 50 rotates, the moving scroll 50 can rotate relative to the adjusting scroll 60. At this time, while the first compression section formed between the moving scroll 50 and the stationary scroll 40 compresses the refrigerant, the second compression section formed between the moving scroll 50 and the adjusting scroll 60 can also compress the refrigerant. This allows the refrigerant compressed by the first compression section to enter the second compression section for further compression. The scroll compressor is a two-stage compressor, which can meet the usage requirements under low ambient temperature heating conditions while ensuring high energy efficiency. Thus, a single scroll compressor can achieve the advantages of high-efficiency heating under low ambient temperature heating conditions and high-efficiency cooling under high ambient temperature cooling conditions.

[0046] In this embodiment of the invention, the clutch slider 30 has an annular columnar structure, and the annular columnar structure is coaxially arranged with the electromagnetic coil 20; the adjusting scroll plate 60 is provided with a first through hole in the circumferential direction, and the annular columnar structure is provided with a first protrusion structure 301 in the axial direction, the first protrusion structure 301 passing through the first through hole.

[0047] See Figure 6 The clutch slider 30 has an annular columnar structure. The hollow part in the middle of the annular columnar structure can be fitted with an adjusting scroll plate 60. The adjusting scroll plate 60 can be provided with a first through hole in the axial direction. The axis of the first through hole can be set substantially parallel to the axis of the adjusting scroll plate 60. The first protrusion structure 301 of the clutch slider 30 passes through the first through hole, thereby constraining the adjusting scroll plate 60 by constraining the clutch slider 30. The structure is simple, safe and reliable.

[0048] In practical applications, on the end face of the annular columnar structure perpendicular to its axis, the first protrusion structure 301 can be uniformly and symmetrically arranged along the circumference of the annular columnar structure. For example, eight first protrusion structures 301 can be provided along the circumference. The eight first protrusion structures 301 can be symmetrically arranged about the axis of the annular columnar structure, that is, the central angles of adjacent first protrusion structures 301 are equal. The structure is simple, easy to process, and can also ensure the reliability and stability of motion transmission between the clutch slider 30 and the adjusting scroll plate 60. The first protrusion structure 301 can be a columnar structure, such as a triangular prism, cylinder, cuboid, etc., and the embodiments of the present invention do not limit this.

[0049] In this embodiment of the invention, the moving scroll disk 50 is provided with a first groove structure 501; when the clutch slider 30 is engaged with the moving scroll disk 50, the first groove structure 501 and the first protrusion structure 301 are in concave-convex cooperation.

[0050] See Figure 4 The first protrusion structure 301 of the clutch slider 30 passes through the adjusting scroll plate 60. When the clutch slider 30 is engaged with the moving scroll plate 50, the first protrusion structure 301 can cooperate with the first groove structure 501 of the moving scroll plate 50. Through this structure, the moving scroll plate 50 can transmit motion to the clutch slider 30, and then through the clutch slider 30, the motion is transmitted to the adjusting scroll plate 60. The structure is simple, safe and reliable.

[0051] It should be noted that during the process of the electromagnetic coil 20 repelling the clutch slider 30, the clutch slider 30 may not be engaged with the moving scroll plate 50. At this time, as the moving scroll plate 50 rotates, the first protrusion structure 301 of the clutch slider 30 can be inserted into the first groove structure 501, so as to achieve successful engagement between the clutch slider 30 and the moving scroll plate 50.

[0052] In practical applications, the first protrusion structure 301 of the clutch slider 30 can also be provided with a groove on the end face of the moving scroll plate 50, and the moving scroll plate 50 can be provided with a protrusion. The groove can cooperate with the protrusion to realize the engagement between the clutch slider 30 and the moving scroll plate 50.

[0053] In this embodiment of the invention, the fixed disk 10 is provided with a second protrusion structure 101, and the clutch slider 30 is provided with a second groove structure 302; when the clutch slider 30 is engaged with the fixed disk 10, the second groove structure 302 and the second protrusion structure 101 are in concave-convex cooperation.

[0054] See Figure 5 The second groove structure 302 and the second protrusion structure 101 are in concave-convex cooperation. Through this concave-convex cooperation structure, the fixed disk 10 can constrain the rotation of the adjusting scroll disk 60 in the circumferential direction. When the moving scroll disk 50 rotates, the relative rotation between the moving scroll disk 50 and the adjusting scroll disk 60 can be realized, thereby realizing the compression of the refrigerant by the second compression section. The structure is simple, safe and reliable.

[0055] In this embodiment of the invention, the inner wall of the fixed disk 10 is provided with a third groove structure 102 along the circumferential direction, and the electromagnetic coil 20 is embedded in the third groove structure 102. The inner wall of the fixed disk 10 is the cavity surface on which the adjusting scroll plate 60 is provided.

[0056] See Figure 4 and Figure 5 The electromagnetic coil 20 is embedded in the third groove structure 102. By controlling the current of the electromagnetic coil 20, the change of the magnetic pole of the electromagnetic coil 20 can be controlled, thereby achieving the repulsion and attraction of the clutch slider 30. The structure is simple, the function is reliable, and it can also avoid affecting the sealing performance of the internal cavity of the compressor.

[0057] In this embodiment of the invention, the fixed disk 10 is provided with a second through hole in the circumferential direction; the fixed disk 10 is provided with a third through hole in the axial direction.

[0058] See Figure 2 A second through hole can be provided in the circumference of the fixed disk 10 to guide the gas compressed by the first compression section into the second compression section for further compression and work, or to discharge the gas compressed by the first compression section through the second compression section; a third through hole is provided in the axial direction of the fixed disk 10, which can guide the compressed gas to the exhaust chamber of the compressor. The structure is simple and easy to implement.

[0059] In this embodiment of the invention, the scroll compressor further includes a one-way valve 90; the one-way valve 90 is disposed at the third through hole and fixedly connected to the fixed plate 10; the one-way valve 90 is used to discharge compressed air. The one-way valve 90, disposed at the third through hole, prevents compressed gas in the exhaust chamber from re-entering the compression section via the third through hole, resulting in a simple structure that is easy to implement.

[0060] In this embodiment of the invention, the scroll compressor further includes a motor 80; the output shaft of the motor 80 is fixedly connected to the moving scroll disk 50. The motor 80 can drive the moving scroll disk 50 to rotate, thereby realizing the compression function of the scroll compressor. The structure is simple and easy to implement.

[0061] In this embodiment of the invention, the scroll compressor further includes a bearing 70; the inner ring of the bearing 70 is fixedly connected to the output shaft of the motor 80, and the outer ring of the bearing 70 is fixedly connected to the stationary scroll plate 40. By providing the bearing 70 between the stationary scroll plate 40 and the output shaft of the motor 80, the gas compressed by the first compression section can be discharged into the channel of the compressor body through the gap between the inner and outer rings of the bearing 70. At the same time, the reliability and stability of the movement of the output shaft of the motor 80 can also be ensured.

[0062] This invention also provides an air conditioning system, which includes the scroll compressor described above.

[0063] An air conditioning system provided in this embodiment of the invention features an electromagnetic coil 20 that can engage the clutch slider 30 with the moving scroll plate 50, preventing relative rotation between the adjusting scroll plate 60 and the moving scroll plate 50. When the moving scroll plate 50 rotates, the adjusting scroll plate 60 rotates synchronously with it. At this time, the first compression section formed between the moving scroll plate 50 and the stationary scroll plate 40 compresses the refrigerant. The scroll compressor is a single-stage compressor, capable of meeting usage requirements under high ambient temperature cooling conditions while ensuring high energy efficiency. The electromagnetic coil 20 can also engage the clutch slider 30 with the fixed plate 10, preventing relative rotation between the adjusting scroll plate 60 and the fixed plate 10. When the moving scroll plate 50 rotates, the adjusting scroll plate 60 rotates synchronously with it. When the scroll 50 rotates, the moving scroll 50 can rotate relative to the adjusting scroll 60. At this time, while the first compression section formed between the moving scroll 50 and the stationary scroll 40 compresses the refrigerant, the second compression section formed between the moving scroll 50 and the adjusting scroll 60 can also compress the refrigerant. This allows the refrigerant compressed by the first compression section to enter the second compression section for further compression. The scroll compressor is a two-stage compressor, which can meet the usage requirements under low ambient temperature heating conditions while ensuring high energy efficiency. Thus, a single scroll compressor can achieve the advantages of high-efficiency heating under low ambient temperature heating conditions and high-efficiency cooling under high ambient temperature cooling conditions.
