Description

Technical Field

[0001] The utility model relates to the technical field of compressors, and particularly relates to a compressor vibration damping device and a compressor system. Background Art

[0002] At present, the vibration displacement of a rotary compressor during operation is relatively large. This vibration not only directly acts on the compressor itself, but also is transmitted to the piping system closely connected thereto through mechanical connection. Under the continuous action of this vibration, the piping system will experience significant stress and strain changes, and long-term accumulation is likely to cause fatigue of the piping material, and then lead to piping rupture or loosening at the connection, ultimately resulting in the serious consequence of refrigerant leakage. Especially in the current trend of the refrigeration industry gradually adopting more flammable R32 refrigerant as a substitute, the problem of refrigerant leakage cannot be ignored. Because when the concentration of R32 refrigerant reaches a certain level in a confined space, in case of open fire or electric spark, it is extremely easy to cause a fire or even an explosion, posing a serious threat to the personal safety of users.

[0003] In addition, the rotary compressor and the associated piping vibration problem are directly related to the operating stability and reliability of refrigeration equipment such as air conditioners. Vibration may not only damage the internal components of the equipment, shorten the service life of the equipment, but also lead to a decline in system performance due to faults such as piping loosening and fracture, affecting the refrigeration effect. At the same time, when the vibration is transmitted to the outdoor unit housing, it will also generate a relatively large noise, resulting in a significant decline in the comfort of users.

[0031] Please refer to Figure 1 , this embodiment provides a compressor vibration damping device for damping the compressor 1, including: a solenoid box assembly 2 and a permanent magnet member 3 mounted on the compressor 1. At least one solenoid group is provided in the solenoid box assembly 2. The solenoid group includes two solenoids 4 respectively disposed on both sides of the compressor 1. When the solenoid 4 is energized, an electromagnetic force repulsive to the permanent magnet member 3 can be generated.

[0032] As shown in Table 1 (Vibration Comparison Table of the Original Air Conditioner and the Air Conditioner with the Compressor Vibration Damping Device Added) and Table 2 (Stress Comparison Table of the Original Air Conditioner and the Air Conditioner with the Compressor Vibration Damping Device Added), the electromagnetic repulsive force generated by the solenoids 4 and the permanent magnet member 3 disposed on both sides of the compressor 1 in this embodiment can not only reduce the vibration displacement of the compressor 1, but also reduce the stress and strain of the piping, thereby reducing the noise value and improving the noise quality, and further improving the reliability and comfort of the operation of the refrigeration equipment. At the same time, the structure of the compressor vibration damping device in this embodiment is simple, the production and manufacturing difficulty is low, and the manufacturing cost is low.

[0036] Table 2

[0037]

[0038] Among them, the permanent magnet member 3 can be a permanent magnet to generate natural magnetism, or can be a coil to generate electromagnetic force.

[0039] In this embodiment, the magnetic pole direction of the permanent magnet member 3 is the same as that of the solenoid 4.

[0040] Specifically, the magnetic pole direction of the upper end of the permanent magnet member 3 is the same as that of the upper end of the solenoid 4, and the magnetic pole direction of the lower end of the permanent magnet member 3 is the same as that of the lower end of the solenoid 4.

[0041] After the solenoid 4 is energized, a magnetic field similar to that of a bar magnet is generated around it. The magnetic pole direction of the permanent magnet 3 is the same as that of the solenoid 4. Since like magnetic poles repel each other, when the compressor 1 vibrates, it will be subjected to the electromagnetic repulsion force of the solenoid 4, thereby being able to reduce the vibration displacement of the compressor 1. Since the electromagnetic repulsion force is a non-contact force, friction and wear in the traditional contact mechanism can be avoided.

[0042] In this embodiment, the two solenoids 4 in the solenoid group are symmetrically distributed on both sides of the compressor 1.

[0043] The two solenoids 4 in the solenoid group are symmetrically distributed on both sides of the compressor 1. Therefore, the distance from each pair of solenoids 4 to the compressor 1 is equal. When the compressor 1 starts up for an instant, the electromagnetic forces of each pair of solenoids 4 on the compressor 1 cancel each other out. After the compressor 1 starts, assuming that the cylinder body of the compressor 1 vibrates to the right. At this time, the distance from the solenoid 4 on the right to the compressor 1 is L1, and the magnetic repulsion force of the solenoid 4 on the right on the compressor 1 is F1; the distance from the solenoid 4 on the left to the compressor 1 is L2, and the magnetic repulsion force of the solenoid 4 on the left on the compressor 1 is F2. Since the magnetic pole direction of the solenoid 4 is the same as that of the permanent magnet 3, when the distance between the two magnets is smaller, the magnetic repulsion force is greater. When L1 < L2, F1 > F2. Therefore, at this time, the compressor 1 will be subjected to a magnetic repulsion force with a magnitude of F1 - F2 and a direction to the left, which causes the compressor 1 to reduce the vibration displacement to the right, thereby reducing the stress and strain of the pipeline.

[0044] The symmetrical distribution of the two solenoids 4 helps to achieve the balance of the repulsion force received by the compressor 1. During the operation of the compressor 1, the symmetrically distributed solenoids 4 can cancel or weaken the vibration and unbalanced forces generated by mechanical operation, thereby reducing noise and vibration and improving the stability and reliability of the operation of the compressor 1.

[0045] In this embodiment, a plurality of solenoid groups are provided, and the plurality of solenoid groups are distributed around the compressor 1.

[0046] When a plurality of solenoid groups are distributed around the compressor 1, the magnetic field they jointly generate can form a more uniform and dense magnetic field environment around the compressor 1. This uniform magnetic field distribution can ensure that no matter where the compressor 1 vibrates and displaces in all directions, the permanent magnet 3 on it can generate a repulsion force with the magnetic field, thereby being able to reduce the vibration displacement of the compressor 1 in all directions, helping to reduce vibration and noise, and improving the stability and durability of the equipment.

[0047] In this embodiment, please refer to Figure 2 and Figure 3 , the solenoid box assembly 2 includes a solenoid box 5. An accommodation cavity 6 is provided in the solenoid box 5. The compressor 1 is arranged in the accommodation cavity 6, and the solenoid group is arranged on the solenoid box 5.

[0048] Integrating the solenoid group on the solenoid box 5 helps to achieve unified management and control of multiple solenoids 4. This centralized layout simplifies the electrical connections and wiring, making maintenance and repair more convenient.

[0049] In this embodiment, please refer to Figure 4 , the solenoid box assembly 2 further includes: a top cover 7, and the top cover 7 is connected to the solenoid box 5 to fix the solenoid 4 inside the solenoid box 5.

[0050] The tight connection between the top cover 7 and the solenoid box 5 forms a closed space, which provides good protection for the solenoid 4. It can prevent dust, moisture, corrosive gases, etc. in the external environment from entering the inside of the solenoid 4, thus keeping the solenoid 4 clean and dry and avoiding damage or performance degradation.

[0051] Among them, the connection method between the top cover 7 and the solenoid box 5 can be an integrated setting or a separated setting. When the top cover 7 and the solenoid box 5 are in a separated setting, the top cover 7 and the solenoid box 5 can be connected by means of a buckle 21 or by means of screws. Preferably, the top cover 7 and the solenoid box 5 are connected by means of screws. Specifically, screw holes 8 are provided on both the top cover 7 and the solenoid box 5 (as Figures 2 - 4 shown), and the top cover 7 and the solenoid box 5 are connected by screws passing through the two screw holes 8. The screw connection makes the screws tightly fit with the screw holes 8 on the solenoid box 5 and the top cover 7 by rotating the screws, thus achieving a firm connection. This connection method has good self-locking property, which can effectively prevent the top cover 7 from loosening or falling off during the operation of the equipment, ensuring the safe and stable operation of the solenoid 4.

[0052] Furthermore, a pressing strip 9 is provided on the top cover 7 (as Figure 4 shown), and the pressing strip 9 is provided corresponding to the solenoid 4 to fix the solenoid 4 inside the solenoid box 5 and prevent the solenoid 4 from shaking and generating abnormal noises.

[0053] In this embodiment, a wire trough 10 is provided inside the solenoid box 5 (as Figure 3 shown), and the wire trough 10 is used to place the connecting wires between the main board and the solenoid 4. When the compressor 1 starts, the main board supplies power to the solenoid 4 through the connecting wires, causing the solenoid 4 to work electrically.

[0054] In this embodiment, a number of mounting feet 11 are provided inside the solenoid box 5 (as Figure 2 shown), and the solenoid box assembly 2 is fixed on a component (such as a chassis, etc.) by means of a number of mounting feet 11 with screws.

[0055] Furthermore, please refer to Figures 2 - 5, the compressor 1 includes a compressor body 12 and a liquid storage tank 13 which are connected to each other. The accommodation cavity 6 includes a compressor body accommodation cavity 14 and a liquid storage tank accommodation cavity 15 which are in communication with each other. The compressor body 12 is disposed in the compressor body accommodation cavity 14, and the liquid storage tank 13 is disposed in the liquid storage tank accommodation cavity 15.

[0056] The designs of the compressor body accommodation cavity 14 and the liquid storage tank accommodation cavity 15 can ensure that the solenoids 4 around them can respectively generate acting forces on the compressor body 12 and the liquid storage tank 13 in directions opposite to the vibration displacement directions. Thereby, the vibration displacements of the compressor body 12 and the liquid storage tank 13 can be respectively reduced, more precise vibration suppression can be achieved, and further the reliability and stability of the compressor 1 can be improved.

[0057] Further, please refer to Figure 6 , the permanent magnet member 3 includes a first permanent magnet member 16 and a second permanent magnet member 17 which are both in an annular structure. The first permanent magnet member 16 is sleeved on the outer surface of the compressor body 12, and the second permanent magnet member 17 is sleeved on the outer surface of the liquid storage tank 13.

[0058] The annular structure can closely fit on the outer surfaces of the compressor body 12 and the liquid storage tank 13 without occupying extra space, thereby improving the space utilization rate of the overall device. This compact design helps to reduce the overall size of the device, facilitating installation and layout. The annular permanent magnet member 3 is closely attached to the outer surfaces of the compressor body 12 and the liquid storage tank 13, and the electromagnetic repulsive force generated between it and the solenoid 4 helps to enhance the stability of the compressor 1. This stability can reduce vibration, lower noise and extend the service life of the device.

[0059] Among them, the permanent magnet member 3 can be installed from the top of the compressor body 12 and the liquid storage tank 13 downwards so that it firmly adheres to the compressor body 12 and the liquid storage tank 13.

[0060] It should be noted that when installing the solenoid box assembly 2 and the permanent magnet member 3 in the manner as Figures 1 - 6 , it can reduce the lateral displacement of the compressor 1, that is, the tangential vibration displacement. Those skilled in the art can also design other structures and installation methods with reference to the principle of this embodiment to reduce the displacement of the compressor 1 in other directions.

[0061] In addition, the magnetic pole directions of the first permanent magnet 16 and the second permanent magnet 17 may be the same or different. When the magnetic pole directions of the first permanent magnet 16 and the second permanent magnet 17 are the same, the magnetic pole directions of the solenoids 4 respectively corresponding to the first permanent magnet 16 and the second permanent magnet 17 are also the same, and are the same as the magnetic pole directions of the first permanent magnet 16 and the second permanent magnet 17. When the magnetic pole directions of the first permanent magnet 16 and the second permanent magnet 17 are different, the magnetic pole directions of the solenoids 4 respectively corresponding to the first permanent magnet 16 and the second permanent magnet 17 are different. The magnetic pole direction of the solenoid 4 corresponding to the first permanent magnet 16 is the same as the magnetic pole direction of the first permanent magnet 16, so as to generate a repulsive force on the first permanent magnet 16. The magnetic pole direction of the solenoid 4 corresponding to the second permanent magnet 17 is the same as the magnetic pole direction of the second permanent magnet 17, so as to generate a repulsive force on the second permanent magnet 17.

[0062] In this embodiment, please refer to Figure 7 , the solenoid 4 includes: a housing 18 and a coil 19, and the coil 19 is wound around the outer surface of the housing 18.

[0063] The coil 19 is directly wound around the housing 18, without the need for additional space to accommodate the coil 19, thus achieving structural compactness. This design makes the solenoid 4 more compact in volume, facilitating installation and use in a limited space. At the same time, due to the relatively simple structure of the solenoid 4, it can be mass-produced using an automated production line, improving production efficiency and reducing costs.

[0064] Among them, the housing 18 is usually designed as a hollow cylindrical plastic tube. The plastic material is relatively inexpensive, and the production process of the cylindrical plastic tube is relatively simple, resulting in a low manufacturing cost. This helps to reduce the overall cost of the product.

[0065] Furthermore, the solenoid 4 further includes: an iron core 20, and the iron core 20 is installed inside the housing 18 to strengthen the magnetic field of the solenoid 4.

[0066] Furthermore, a number of buckles 21 are provided on the housing 18. After the iron core 20 is installed inside the housing 18, pressing the buckles 21 can fix the iron core 20, thereby preventing the iron core 20 from shaking and generating abnormal noises.

[0067] In this embodiment, it further includes: a displacement detection member 22 (as shown in Figure 5 ), and the displacement detection member 22 is installed on the compressor 1.

[0068] The displacement detector 22 can collect the vibration displacement value of the compressor 1, convert the vibration displacement value into an electrical signal and transmit it to the main board. The main board adjusts the magnitude of the current supplied to the solenoid 4 based on the real-time vibration displacement magnitude of the compressor 1. The larger the vibration displacement, the larger the current value supplied to the solenoid 4. Conversely, the smaller the vibration displacement, the smaller the current value supplied to the solenoid 4, until the vibration displacement value of the compressor 1 meets the requirements of the set range.

[0069] Among them, the displacement detector 22 is a vibration displacement sensor, such as an optical sensor, a capacitive sensor, a magnetoelectric sensor, etc.

[0070] Furthermore, a plurality of displacement detectors 22 are provided, and the plurality of displacement detectors 22 are evenly installed on the compressor 1.

[0071] A single displacement detector 22 may be affected by local factors (such as vibration, temperature gradient, etc.) and generate errors. The average readings of the plurality of displacement detectors 22 can partially cancel these local errors and improve the overall measurement accuracy. At the same time, the setting of the plurality of displacement detectors 22 constitutes a redundant system. Even if one or a few of the detectors fail or malfunction, the other detectors can still continue to work, ensuring the continuity and reliability of displacement monitoring.

[0072] The following details the working process of the compressor vibration damping device in the case where 3 displacement detectors 22 are evenly distributed at equal intervals from bottom to top on the compressor 1:

[0073] After the compressor 1 runs stably (that is, the frequency and exhaust temperature of the compressor 1 remain unchanged), when the solenoid 4 is not powered on, assuming that the vibration displacement value of the compressor 1 at this time is S0 (S0 takes the maximum value among the 3 displacement detectors 22), an example is given by controlling the real-time vibration displacement value of the compressor 1 to be ≤1 / 3S0. Among them, the real-time vibration displacement value of the compressor 1 can be controlled within a smaller range, such as 1 / 4S0 or 1 / 5S0, etc., but the adjustment time required will be longer.

[0074] Parameter description is as follows: the operating frequency of the compressor 1 - F; the exhaust temperature of the compressor 1 - T; the real-time vibration displacement of the compressor 1 - S; the real-time current of the solenoid 4 - I; when the manufacturer measures under the rated refrigeration condition that 0 < S ≤ 1 / 3S0, the current of the solenoid 4 - I0 (hereinafter referred to as the initial current); the number of cycles - X, for 1 cycle, X = 1, for 2 cycles, X = 2, the number of cycles refers to the number of cycles that do not satisfy 0 < S ≤ 1 / 3S0, and so on.

[0075] Step 1: When the air conditioner is turned on, detect whether the operating frequency F of the compressor 1 of the air conditioner changes. If it is detected that the operating frequency F of the compressor 1 remains unchanged continuously within 30 seconds, proceed to the next step of exhaust temperature T detection. Otherwise, re-detect the operating frequency F of the compressor 1;

[0076] Step 2: Detect the exhaust temperature T of the compressor 1. If the detected exhaust temperature T of the compressor 1 remains unchanged continuously within 3 minutes, then the maximum value S of the measured vibration displacement of the compressor 1 within these 3 minutes is S0. At this time, the main board controls the solenoid 4 to be energized, and at this time, the solenoid 4 obtains the initial current I0. If the detected exhaust temperature T of the compressor 1 changes within 3 minutes, then re-detect the exhaust temperature T of the compressor 1;

[0077] Step 3: After the solenoid 4 obtains the initial current I0, detect the real-time vibration displacement value S of the compressor 1. If the vibration displacement value S satisfies the requirement of 0 < S ≤ 1 / 3S0, then keep the current I = I0 in the solenoid 4 unchanged. Otherwise, the main board controls to increase the current I of the solenoid 4. At this time, the solenoid 4 obtains the current I = (X / 2 + 1)I0, where X represents the number of cycles (for 1 cycle, X = 1; for 2 cycles, X = 2, and so on). For example, when the detected vibration displacement value S of the compressor 1 for the first time does not satisfy the set requirement of 0 < S ≤ 1 / 3S0, the main board controls to increase the current I passing through the solenoid 4 to I = (X / 2 + 1)I0 = (1 / 2 + 1)I0 = 1.5I0;

[0078] Step 4: After the main board controls to increase the current of the solenoid 4, detect the real-time vibration displacement value S of the compressor 1 again. If the vibration displacement value S satisfies the requirement of 0 < S ≤ 1 / 3S0, then keep the current I = (X / 2 + 1)I0 in the solenoid 4 unchanged. Otherwise, the main board controls to continue increasing the current of the solenoid 4. At this time, the solenoid 4 obtains the current I = ((X + 1) / 2 + 1)I0, and then detect the real-time vibration displacement value S of the compressor 1 again until the vibration displacement value S of the compressor 1 satisfies the set range requirement of 0 < S ≤ 1 / 3S0.

[0079] After the vibration displacement value S of the compressor 1 satisfies the set range requirement of 0 < S ≤ 1 / 3S0, the main board records the vibration displacement value Si of the compressor 1 and the current value Ii of the solenoid 4 at this time. During the next operation, if the main board detects that the vibration displacement value S of the compressor 1 is the same or close, it will automatically perform matching and directly give the current Ii to the solenoid 4 (instead of the initial current I0), so that the vibration displacement of the compressor 1 can reach the set range requirement fastest. The more times the air conditioner is used, the more data pairs (i.e., the corresponding relationship between the vibration displacement value Si of the compressor 1 and the current value Ii of the solenoid 4) are recorded and saved by the main board. Thus, the adjustment time can be significantly shortened, and the product reliability and comfort can be improved.

[0080] This embodiment also provides a compressor system, including: the compressor 1 and the compressor vibration damping device of the above embodiment.
