In the present invention, when the coolant needs to be supplemented, the convex rod moves downward, drives the limit ring to slide on the threaded rod, and squeezes the spring to deform it. During this process, the internal space of the inner tube changes, and the liquid impacts the second sphere. With the buoyancy effect, the first sphere and the second sphere no longer completely block the pipeline. The internal pressure difference of the system causes the liquid in the lifting tube to flow to the top and be discharged through the first liquid outlet pipe. When the supplement is stopped, the convex rod moves upward, the spring returns to its original state, the second sphere and the first sphere descend, and the pipeline is blocked again to prevent the liquid from being discharged.

The intermittent supplement can meet the supplement amount and avoid excessive coolant.

Description

Technical Field

[0001] The invention relates to the technical field of energy storage chillers, and in particular to a high-precision and high-power container energy storage chiller. Background Art

[0002] In the refrigeration industry, chillers are mainly divided into air-cooled and water-cooled types. According to the type of compressor, they are further subdivided into screw chillers, scroll chillers and centrifugal chillers. In terms of temperature control, chillers can be divided into low-temperature industrial chillers and normal temperature chillers. In the chiller system, coolant, as the key refrigerant, is responsible for absorbing and releasing heat in the refrigeration cycle to achieve the cooling effect. However, due to system operation, leakage, evaporation and other factors, the coolant will be consumed during use. Therefore, in order to ensure the stable operation of the system, the coolant needs to be replenished regularly.

[0003] For example, the “tank container integrated air-cooled chiller unit” with publication number CN117302771A comprises: a support frame, wherein a support plate is fixedly installed inside the support frame near one side.

[0004] However, in the prior art, during the process of replenishing the coolant, if the replenishment amount is insufficient, the refrigeration efficiency of the system will decrease and the cooling demand cannot be met. In the actual process, since the chiller runs continuously, continuous replenishment is required to ensure its stable operation, and over-replenishment is very likely to occur. Excessive coolant will first lead to thermal expansion problems. During the operation of the chiller, as the temperature rises, the coolant will expand due to heat. If it is already filled with excess coolant, then when the temperature rises, the coolant will have nowhere to go, resulting in increased pressure, and eventually causing overflow in the system, which not only wastes coolant, but also damages the structure and performance of the chiller. In addition, excessive coolant will also cause energy waste. Too much coolant means that the system requires more energy to drive its circulation, thereby increasing energy consumption and operating costs. Summary of the invention

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In the present invention, when the coolant needs to be replenished, the protruding rod moves downward, driving the limit ring to slide on the threaded rod and squeezing the spring to deform it. During this process, the internal space of the inner tube changes, and the liquid impacts the second sphere. With the buoyancy effect, the first sphere and the second sphere no longer completely block the pipeline. The internal pressure difference of the system causes the liquid in the lifting tube to flow to the top and be discharged through the first liquid outlet pipe. When the replenishment stops, the protruding rod moves upward, the spring returns to its original state, the second sphere and the first sphere descend, and the pipeline is blocked again to prevent the liquid from being discharged. During the whole process, the water inlet receives the discharged liquid and transports it to the drain outlet through the water inlet pipe and the liquid outlet to complete the replenishment of the coolant. This control system ensures the accuracy and efficiency of the coolant replenishment, and the intermittent replenishment can not only meet the replenishment amount, but also avoid excessive replenishment.

[0019] 2. In the present invention, the top cover is tightly connected to the outer shell, providing a solid foundation for the system and facilitating installation and maintenance. The reduction motor drives the cam to rotate, and applies a periodic force to the convex rod through its special profile, driving the lifting tube to move up and down. During the lifting process, the limit ring slides on the threaded rod to ensure stability and allow adjustment. The connection between the threaded rod and the threaded groove allows the position of the threaded rod to be adjusted by twisting the threaded rod, thereby changing the movement range of the limit ring and limiting the rising height of the lifting tube under the action of the spring. This adjustment mechanism can accurately control the lifting distance of the lifting tube under the action of the cam, thereby affecting the water output of the first liquid outlet pipe. By adjusting the lifting distance, the amount of discharged liquid can be controlled, thereby achieving precise control of the water output.

[0020] 3. In the present invention, the refrigeration system achieves efficient refrigeration effect through the coordinated work of core components such as the compressor, the condensing machine body, the expansion valve and the evaporator. The compressor compresses the low-pressure, low-temperature refrigerant gas into a high-pressure, high-temperature gas, providing power for the refrigeration cycle. The condensing machine body cools the refrigerant gas and condenses it into a high-pressure liquid through heat exchange, releasing a large amount of heat. The expansion valve changes the refrigerant liquid into a low-pressure, low-temperature state by reducing the pressure, and produces a gas-liquid mixture to prepare for the evaporation process. In the evaporator, the low-pressure, low-temperature refrigerant liquid quickly evaporates into a gaseous state, absorbs heat from the surrounding environment, and achieves rapid refrigeration. At the same time, the high-speed rotation of the fan and the protection of the protective cover ensure the effective discharge of heat and the safe operation of the system. In addition, the filter provided in the system effectively intercepts impurities in the refrigerant liquid, ensures the purity of the refrigerant, and further ensures the stable operation of the refrigeration system.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example 1: Reference Figure 1 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown: a high-precision, high-power container energy storage chiller, comprising an upper frame 1 and a lower frame 6, a plurality of support frames 11 are fixedly connected to the top of the lower frame 6, the top of the support frame 11 is fixedly connected to the bottom of the upper frame 1, a plurality of fans 3 are installed on the top of the upper frame 1, a condenser body 5 is installed at the center of the inner side of the lower frame 6, two compressors 7 are installed on one side of the condenser body 5, and a plurality of liquid discharge mechanisms 4 are installed on the side wall of the upper frame 1;

[0033] The liquid outlet mechanism 4 comprises an outer shell 41 and a top cover 42. A fixing block 45 is fixedly connected to the bottom center of the outer shell 41. An inner tube 46 is fixedly connected to the top center of the fixing block 45. A lifting tube 43 is sleeved on the outer surface of the top end of the inner tube 46. A limiting ring 434 is fixedly connected to the outer surface of the bottom end of the lifting tube 43. A convex rod 431 is fixedly connected to the top of the lifting tube 43. A first liquid outlet pipe 432 is fixedly connected to one side of the top end of the lifting tube 43. A storage groove 433 is provided at the top end of the lifting tube 43. A first sphere 435 is installed inside the storage groove 433. A water receiving pipe 44 is installed on one side of the fixing block 45. A water receiving port 441 is fixedly connected to the top end of the water receiving pipe 44. A threaded groove 453 is provided on one side of the fixing block 45. A threaded rod 48 is provided on one side of the lifting tube 43. The bottom end of the threaded rod 48 passes through the limiting ring 434. The bottom end of the threaded rod 48 is threadedly connected to the threaded groove 453. The threaded rod 48 is slidably connected to the limiting ring 434. A water inlet 462 is provided at the bottom end of the inner tube 46.

[0034] In this embodiment, when the coolant needs to be replenished, the protruding rod 431 is moved downward. The downward movement of the protruding rod 431 causes the limit ring 434 connected thereto to slide on the surface of the threaded rod 48 and move in the vertical direction. In this process, the limit ring 434 contacts and squeezes the spring 47, causing it to deform. The squeezing of the spring 47 provides the necessary elastic force for the entire system, ensuring that it can be restored to its original state at the appropriate time.

[0035] As the stop ring 434 descends, it changes the space inside the inner tube 46. This change causes the liquid in the inner tube 46 to be impacted, especially directly impacting the second sphere 461. Due to the impact force and buoyancy of the liquid, the first sphere 435 and the second sphere 461 that may have played a blocking role are forced to move and can no longer completely block the pipeline.

[0036] When the two spheres cannot be blocked, a pressure difference will appear inside the system. This pressure difference will cause the liquid inside the lifting tube 43 to flow to the top through the storage tank 433, and finally be discharged through the first liquid outlet pipe 432. When it is necessary to stop replenishing the coolant, the protruding rod 431 will move upward, driving the limit ring 434 back to its original position. In this process, the spring 47 gradually restores its original shape and generates an upward elastic force. At the same time, due to the effect of gravity, the second sphere 461 and the first sphere 435 will begin to descend. As the lifting tube 43 moves upward and the spheres descend, the first sphere 435 will block the outlet of the storage tank 433 again. In this way, the first liquid outlet pipe 432 will not be able to discharge the liquid again, thereby achieving precise control of the replenishment of the coolant.

[0037] In the whole process, the water receiving port 441 plays the role of receiving the liquid discharged from the first liquid outlet pipe 432. The water receiving pipe 44 then transports the liquid to the drain port 452 through the liquid outlet 451, and finally completes the replenishment of the coolant.

[0038] Embodiment 2: Figure 6-9 As shown, a spring 47 is installed between the limit ring 434 and the fixed block 45, and the spring 47 is sleeved on the outer surface of the inner tube 46. One end of the first liquid outlet pipe 432 is located above the water receiving port 441. The top diameter of the threaded rod 48 is larger than the aperture of the through hole on the surface of the limit ring 434. The inner cavity at the bottom end of the lifting tube 43 is provided with a second sphere 461, and the second sphere 461 is located above the inner tube 46. A drainage port 452 is provided at the center of the bottom of the fixed block 45, and a liquid outlet 451 is provided on one side of the top of the drainage port 452. The liquid outlet 451 is connected to the bottom end of the water receiving pipe 44. The top cover 42 is clamped with the outer edge of the top of the shell 41, and a reduction motor 421 is fixedly installed on the top of the top cover 42. A cam 422 is installed at the bottom of the top cover 42. The top end of the cam 422 passes through the top cover 42, and the top end of the cam 422 is fixedly connected to the output end of the reduction motor 421, and the cam 422 abuts against the convex rod 431.

[0039] In this embodiment, first, the top cover 42 is used as a connection point, which is closely matched with the shell 41 to provide a stable foundation for the entire system. Through this connection, not only the integrity of the system is guaranteed, but also the installation and maintenance of the system are made more convenient.

[0040] Next, the reduction motor 421 acts as a power source to drive the cam 422 to rotate. During the rotation of the cam 422, its specific profile design causes the convex rod 431 to be subjected to a periodic force. This force enables the convex rod 431 to drive the lifting tube 43 to move up and down.

[0041] The limiting ring 434 plays a vital role in the movement of the lifting tube 43. The limiting ring 434 slides on the surface of the threaded rod 48, and this sliding not only ensures the stability during the lifting process, but also provides the possibility for subsequent adjustment.

[0042] The connection between the threaded rod 48 and the threaded groove 453 provides the possibility of adjustment for the entire system. By twisting the threaded rod 48, the relative position between the threaded rod 48 and the threaded groove 453 can be changed, thereby adjusting the position of the threaded rod 48. This position change will directly affect the movement range of the limit ring 434, thereby limiting the rising height of the lifting tube 43 under the elastic action of the spring 47.

[0043] By using this adjustment method, the lifting distance of the lifting tube 43 under the action of the cam 422 can be accurately controlled. The change of this distance will directly affect the water output of the first liquid outlet pipe 432. When the lifting tube 43 descends, the liquid inside it is subjected to pressure and will be discharged through the first liquid outlet pipe 432. The lifting distance of the lifting tube 43 determines the amount of discharged liquid, thereby achieving accurate control of the water output.

[0044] Embodiment 3: According to Figure 1-5 As shown, two heat sinks 2 are symmetrically fixedly connected at the bottom of the upper frame 1, and evaporators 21 are installed on both sides of the inner cavity of the heat sink 2. The side walls of the evaporator 21 are fixedly connected with a return pipe 22, and the bottom end of the return pipe 22 is fixedly connected with the expansion valve 8. The expansion valve 8 is fixedly connected to both sides of the top of the condenser body 5. The third pipeline 83 is fixedly connected to the bottom of one side of the expansion valve 8, and one end of the third pipeline 83 is fixedly connected to one side of the condenser body 5. A first pump 71 is installed on one side of the compressor 7. The bottom of the first pump 71 is fixedly connected to the lower frame 6. A second pipeline 82 is fixedly connected to one side of the compressor 7, and the second pipeline 82 is fixedly connected to the expansion valve 8. Two second liquid outlet pipes 51 are fixedly connected to the bottom end of one side of the condenser body 5. One end of the second liquid outlet pipe 51 is fixedly connected to the first pump 71. The top of the first pump 71 is fixedly connected with the first pipeline 81, and the first pipeline 81 is fixedly connected to the expansion valve 8. A drain pipe 72 is fixedly connected to one side of the evaporator 21, and the bottom end of the drain pipe 72 is fixedly connected to the compressor 7. A protective cover 31 is fixedly connected to the top of the fan 3, and a second pump 9 is installed on one side of the condenser body 5. A water inlet pipe 91 is fixedly connected to one side of the second pump 9, and a liquid replenishment pipe 411 is fixedly connected to the other side of the second pump 9. The top of the liquid replenishment pipe 411 is fixedly connected to the drain outlet 452.

[0045] In this embodiment, the compressor 7 is the core component of the refrigeration system, which is responsible for sucking in low-pressure and low-temperature refrigerant gas, and reducing the distance between molecules inside it through mechanical compression, making the collision between gas molecules more frequent, thereby rapidly increasing the temperature and pressure of the refrigerant gas. The high-pressure and high-temperature refrigerant gas output by the compressor 7 is transported to the condenser body 5 through a high-temperature and high-pressure pipeline.

[0046] In the condenser body 5, the high-pressure and high-temperature refrigerant gas exchanges heat with the cooling water or cooling air, releases heat, gradually cools and condenses into high-pressure liquid. In this process, the coolant plays a key role. It flows out of the condenser body 5 through the second liquid outlet pipe 51, is pressurized by the first pump 71, and is then transported to the expansion valve 8 through the first pipeline 81.

[0047] The expansion valve 8 is a throttling mechanism in the refrigeration system. Its main function is to reduce the pressure of the high-pressure refrigerant liquid to turn it into a low-pressure, low-temperature refrigerant liquid, and at the same time produce part of the refrigerant flashing into gas to form a gas-liquid mixture. In this process, due to the sudden drop in pressure, the temperature of the refrigerant liquid also decreases accordingly, preparing for the subsequent evaporation process.

[0048] The refrigerant liquid after decompression enters the evaporator 21 again through the second pipe 82. In the evaporator 21, the low-pressure and low-temperature refrigerant liquid absorbs the heat of the surrounding air or other objects and quickly evaporates into a gaseous state. At the same time, the three fans 3 generate a strong wind flow by rotating at high speed, which helps the refrigerant in the evaporator 21 to quickly absorb heat and achieve a rapid cooling effect. The existence of the protective cover 31 not only protects the fan 3 from damage by external objects, but also ensures the safety of the refrigeration system.

[0049] The evaporated refrigerant gas is sucked into the compressor 7 again for the next round of compression and refrigeration cycle. The heat absorbed during the evaporation process is discharged to the outside environment through the heat sink of the evaporator 21 and the fan 3.

[0050] In addition, in order to ensure the purity of the refrigerant liquid and prevent impurities from damaging the refrigeration system, a filter is usually provided at the connection between the second pipe 82 and the expansion valve 8. The filter can effectively intercept impurities in the refrigerant liquid, ensure the purity of the refrigerant liquid, and thus ensure the stable operation of the refrigeration system.

[0051] The method of use and working principle of this device: The compressor 7 is responsible for compressing the low-pressure, low-temperature refrigerant gas to transform it into a high-pressure, high-temperature state. This high-pressure and high-temperature refrigerant is then transported to the expansion valve 8 through the second pipeline 82, where it undergoes decompression and expansion and transforms into a low-temperature and low-pressure state. Next, the refrigerant enters the evaporator 21 through the return pipe 22, absorbs heat from the air or other objects around it in the evaporator 21, and evaporates into a gaseous state. In order to speed up the heat dissipation process, the three fans 3 work together, and the protective cover 31 protects the fan 3. Subsequently, the refrigerant circulates back to the compressor 7 through the drain pipe 72 again, completing the entire refrigeration cycle.

[0052] In addition, the condenser body 5 delivers the cooling liquid to the first pump 71 through the second liquid outlet pipe 51, and the first pump 71 further delivers the cooling liquid to the expansion valve 8 through the first pipe 81. After cooling the liquid, the expansion valve 8 delivers the cooled liquid back to the condenser body 5 through the second pipe 82. In this process, a filter is provided at the connection between the second pipe 82 and the expansion valve 8 to ensure that the liquid is clean and free of impurities.

[0053] By utilizing the convenient connection between the top cover 42 and the housing 41, the reduction motor 421 drives the cam 422 to rotate. During the rotation process, one end of the cam 422 applies a force to the convex rod 431, so that the convex rod 431 drives the lifting tube 43 to move downward together. When the lifting tube 43 moves, the limit ring 434 slides on the surface of the threaded rod 48 to ensure the stability of the lifting process. By adjusting the connection relationship between the threaded rod 48 and the threaded groove 453, the position of the threaded rod 48 can be accurately controlled, so that the top end of the threaded rod 48 can be used to limit the moving distance of the limit ring 434. This adjustment method can accurately control the lifting distance of the lifting tube 43 under the action of the cam 422, and then adjust the water output of the first liquid outlet pipe 432.

[0054] When the coolant is replenished, the downward movement of the protruding rod 431 causes the limiting ring 434 to slide vertically on the surface of the threaded rod 48 and squeeze the spring 47. During this process, the liquid in the inner tube 46 impacts the second sphere 461, and at the same time, the buoyancy prevents the first sphere 435 and the second sphere 461 from blocking the pipeline, resulting in a pressure difference inside the system. This pressure difference causes the liquid in the lifting tube 43 to flow to the top through the storage tank 433 and be discharged from the first liquid outlet pipe 432. When the lifting tube 43 rises, due to gravity and the upward movement of the lifting tube 43, the second sphere 461 and the first sphere 435 fall, and finally the first sphere 435 blocks the outlet of the storage tank 433 again, preventing the liquid from continuing to be discharged.

[0055] During the entire replenishment process, the water receiving port 441 receives the liquid discharged from the first liquid outlet pipe 432 and transports the liquid to the drain port 452 through the water receiving pipe 44 and the liquid outlet 451 to complete the replenishment of the coolant.

[0056] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
