Description

Technical Field

[0001] This invention relates to the field of chiller technology, specifically an energy-saving and environmentally friendly air conditioning chiller. Background Technology

[0002] An air conditioning chiller is a device that provides chilled water to an air conditioning system to achieve air conditioning and cooling functions. Its main components are an evaporator, a condenser, a compressor, a throttling device, and a control system.

[0003] However, traditional chiller units suffer from difficulties in aligning compressor connecting pipes with evaporator pipes during compressor installation due to the lack of effective calibration devices. This makes the installation process cumbersome, inefficient, and difficult to guarantee installation accuracy, thus affecting the overall performance of the unit.

[0004] In traditional evaporators, the flow of chilled water is poor, resulting in insufficient heat exchange between the cooling medium and the chilled water. This leads to unsatisfactory evaporation, which in turn affects refrigeration efficiency and increases energy consumption. Furthermore, after prolonged use, scale easily builds up on the inner walls of the evaporator, and the traditional structure makes it difficult to effectively clean this scale, further reducing heat exchange efficiency.

[0005] Finally, in terms of equipment inspection and maintenance, traditional chiller units lack convenient maintenance access, making it difficult for operators to safely and efficiently inspect and install components on the evaporator and condenser, increasing maintenance difficulty and cost, and also affecting the equipment's uptime.

Detailed Implementation

[0036] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the present invention provides an energy-saving and environmentally friendly air conditioning chiller unit, comprising an evaporator 1, a main structure 2 disposed on one side of the evaporator 1, a stirring structure 3 disposed inside the evaporator 1, a calibration structure 4 disposed on the evaporator 1, a limiting structure 5 disposed on the calibration structure 4, and a maintenance structure 6 disposed at the bottom of the calibration structure 4.

[0038] The main structure 2 includes a condenser 201 and an electrical cabinet 202. The condenser 201 is provided on an open ground on one side of the evaporator 1. A compressor 203 is installed on the evaporator 1 through a calibration structure 4.

[0039] The calibration structure 4 includes two guide rails 401 and a drive frame 402. Two guide rails 401 are fixedly connected to both sides of the evaporator 1. A drive frame 402 is provided on each side of the evaporator 1. Two movable wheels 403 are rotatably connected to the bottom of each drive frame 402, and the movable wheels 403 are rollingly connected to the guide rails 401. Two slide rails 404 are fixedly connected to the top of the two drive frames 402. A second screw 405 is rotatably connected to the evaporator 1, and the second screw 405 is threadedly connected to one of the drive frames 402. A guide shaft 411 is fixedly connected to the evaporator 1, and the other drive frame 402 is connected to the guide shaft. A sliding connection is established between the two slide rails 404, with a mounting plate 407 slidably connected between them. A compressor 203 is bolted to the mounting plate 407. Two rollers 410 are mounted on each side of the mounting plate 407, and the rollers 410 are in rolling connection with the slide rails 404. The slide rails 404 have limiting grooves 408, and two limiting shafts 409 are fixedly connected to the mounting plate 407. The limiting shafts 409 are slidably connected to the limiting grooves 408. A second handwheel 406 is mounted on the end of the second screw 405. When installing the compressor 203, the second handwheel 406 is rotated first, driving the second screw 405... 05. Due to the threaded connection between the second screw 405 and one of the drive frames 402, and the slidable connection between the other drive frame 402 and the guide shaft 411, the two drive frames 402 move along the guide rail 401. The moving wheels 403 at the bottom of the drive frame 402 roll inside the guide rail 401, thereby adjusting the position of the drive frame 402. Then, the limiting structure 5 contacts the limiting position between the mounting plate 407 and the slide rail 404. Then, the handle 506 is pulled, thereby pulling the mounting plate 407. The rollers 410 on both sides of the mounting plate 407 roll on the slide rail 404, while the limiting shaft 409 slides within the limiting groove 408, causing the mounting plate 407 to move along the slide rail. When the mounting plate 407 is moved to its outermost position, the operator can install the compressor 203 onto the mounting plate 407 with bolts. Because the mounting plate 407 extends outwards, the operating space is increased, making the installation of the compressor 203 easier and simpler. After installing the compressor 203, move it to a suitable position so that the compressor 203 connecting pipe is aligned with the evaporator 1 pipe, ensuring that the flange holes on the two pipes are aligned for subsequent installation of fixing bolts. An electrical cabinet 202 is installed at the top of the condenser 201, and a gas-liquid separator 204 is installed at the top of the condenser 201.After the high-pressure liquid refrigerant is depressurized by the throttling device (a standard component of the refrigeration cycle), it enters the evaporator 1. In the evaporator 1, the liquid refrigerant absorbs heat from the chilled water and evaporates into a low-pressure gaseous refrigerant. At the same time, the temperature of the chilled water decreases, becoming the cold source for the air conditioning system. The compressor 203 is installed above the evaporator 1 via the calibration structure 4. During operation, it draws in the low-pressure gaseous refrigerant generated in the evaporator 1, compresses it, and transforms it into a high-pressure, high-temperature gaseous refrigerant. The guide rail 401, drive frame 402, and mounting plate 407 in the calibration structure 4 can adjust the position of the compressor 203 to ensure that it is aligned with the pipes of the evaporator 1, ensuring smooth refrigerant flow and avoiding installation deviations. The resulting leakage or resistance loss, after the high-pressure and high-temperature gaseous refrigerant is discharged from the compressor 203, enters the condenser 201. The condenser 201 removes heat through the cooling medium, cools and liquefies the refrigerant, and converts it into high-pressure liquid refrigerant. The high-pressure liquid refrigerant is then depressurized by the throttling device and enters the evaporator 1 to complete the cycle. The gas-liquid separator 204 separates the liquid impurities present in the refrigerant at this stage to ensure the purity of the refrigerant entering the subsequent stages and avoid affecting the evaporation efficiency. The intelligent control system integrated in the electrical cabinet 202 can automatically adjust the speed of the compressor 203 and the working state of the condenser 201 according to the load changes of the evaporator 1 to achieve "cooling on demand".

[0040] The limiting structure 5 includes two levers 501 and a locking rod 502 fixedly connected to the levers 501. Two levers 501 are slidably connected to the mounting plate 407. The locking rod 502 is slidably connected to the mounting plate 407. Multiple locking holes 503 are linearly arrayed on the slide rail 404, and the locking rod 502 engages with the locking holes 503. Two first springs 505 are fixedly connected between the two levers 501. Two guide rods 504 are fixedly connected inside the mounting plate 407. The levers 501 are slidably connected to the guide rods 504, and the guide rods 504 pass through the first springs 505. A series of... The handle 506 has a U-shaped cross-section. When the two levers 501 are released, the first spring 505 returns to its original position, which in turn causes the two levers 501 to slide. The levers 501 cause the locking rod 502 to slide, and the locking rod 502 then engages with the locking hole 503 on the slide rail 404, thereby fixing the position of the mounting plate 407 and the compressor 203. Then the pipes of the compressor 203 can be connected. If it is necessary to contact the limiting structure 5, the two levers 501 can be pinched. The levers 501 cause the locking rod 502 to disengage from the locking hole 503, thereby adjusting the position of the mounting plate 407. The guide rod 504 improves the stability of the sliding of the levers 501 and prevents the first spring 505 from deviating.

[0041] Specifically, such as Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the stirring structure 3 includes an inner sleeve 301 and a stirring shaft 302. The inner sleeve 301 is fixedly connected inside the evaporator 1, and the stirring shaft 302 is rotatably connected inside the inner sleeve 301. Multiple sets of stirring blades 303 are provided on the stirring shaft 302. A fixing frame 304 is fixedly connected to the end of the evaporator 1. A guide post 321 is slidably connected to the fixing frame 304. A connecting plate 307 is fixedly connected to the ends of the four guide posts 321. A motor 308 is fixedly connected to the connecting plate 307. The evaporator 1... A sealing sleeve 310 is fixedly connected. A drive shaft 311 is rotatably connected to the connecting plate 307. The output end of the motor 308 is fixedly connected to the drive shaft 311. The drive shaft 311 is slidably connected to the sealing sleeve 310. The end of the stirring shaft 302 is provided with a hexagonal insert 320. The drive shaft 311 is slidably connected to the insert 320. When it is necessary to stir the chilled water inside the evaporator 1 to improve the heat exchange efficiency, the motor 308 is started. The motor 308 drives the drive shaft 311 to rotate. The drive shaft 311 passes through the insert 320. The stirring shaft 302 is driven to rotate, and the stirring blades 303 on the stirring shaft 302 stir the chilled water, promoting heat exchange between the cooling medium and the chilled water. Two limiting rings 313 are fixedly connected to the drive shaft 311, and a rotating ring 314 is provided between the two limiting rings 313. The rotating ring 314 is rotatably connected to the drive shaft 311. Multiple fixed posts 312 in a circumferential array are fixedly connected to the evaporator 1. Multiple connecting holes 315 are arranged in a circumferential array on the rotating ring 314, and the fixed posts 312 are inserted into the connecting holes 315. A connecting strip 316 is fixedly connected to the upper part, and a scraper 317 is fixedly connected to the connecting strip 316. The scraper 317 abuts against the inner wall of the inner sleeve 301. A first screw 305 is threadedly connected to the fixing frame 304. A connecting frame 306 is fixedly connected to the connecting plate 307. The first screw 305 is rotatably connected to the connecting frame 306. A first handwheel 309 is installed at the end of the first screw 305. A fixing disk 318 is fixedly connected to the stirring shaft 302. A plurality of circumferentially arranged inserts 319 are fixedly connected to the fixing disk 318.When it is necessary to clean the scale inside the evaporator 1, first turn the first handwheel 309 to rotate the first screw 305. Since the first screw 305 is rotatably connected to the connecting bracket 306, the connecting plate 307 moves on the fixed bracket 304 along with the guide post 321, adjusting the position of the motor 308 and the drive shaft 311. The rotating ring 314 on the drive shaft 311 separates from the fixed post 312. At the same time, the connecting hole 315 on the rotating ring 314 is inserted into the insertion post 319 on the fixed plate 318. Next, start the motor 308, which drives the drive shaft 311 to rotate. The drive shaft 311 drives the stirring shaft 302 to rotate, which drives the fixed plate 318 to rotate. The fixed plate 318 drives the rotating ring 314 to rotate. The rotating ring 314 drives the scraper 317 to rotate through the connecting strip 316. The scraper 317 abuts against the inner wall of the inner sleeve 301, cleaning the scale on the inner wall.

[0042] Specifically, such as Figure 2 , Figure 6 , Figure 10 and Figure 11As shown, the maintenance structure 6 includes a first ladder 601 and a rotating shaft 602. The bottom end of the mounting plate 407 is provided with the first ladder 601, and a rotating shaft 602 is fixedly connected to each end of the first ladder 601. The bottom end of the slide rail 404 is provided with a slide groove 603 with an L-shaped cross section. The rotating shaft 602 is slidably connected to the slide groove 603. A connecting shaft 604 is rotatably connected to the first ladder 601, and a second ladder 605 is fixedly connected to the connecting shaft 604. A fixed ring 606 is fixedly connected, and a sliding ring 607 is slidably connected to the connecting shaft 604. A second spring 608 is fixedly connected between the sliding ring 607 and the fixed ring 606. Multiple limiting rods 609 are provided on the sliding ring 607, and multiple limiting holes 610 are arranged in a circumferential array on the first ladder 601. The limiting rods 609 are inserted into the limiting holes 610. When the first ladder 601 is pulled out from the slide groove 603 at the bottom of the slide rail 404, the rotating shaft 602 slides in the slide groove 603. 02 will fall at the L-shaped end of the slide 603, thus fixing the end position of the first ladder 601. Then, rotate the first ladder 601 to unfold it, and then slide the slip ring 607. The slip ring 607 slides on the connecting shaft 604, compressing the second spring 608. The limiting rod 609 on the slip ring 607 separates from the limiting hole 610 on the first ladder 601. At this time, the second ladder 605 can be rotated, so that the second ladder 605 drives the connecting shaft 604 to rotate to a suitable angle. Then, release the slip ring 607. Under the action of the second spring 608, the limiting rod 609 is inserted into the limiting hole 610 to fix the position of the second ladder 605. The operator can then reach the top of the evaporator 1 through the first ladder 601 and the second ladder 605 to inspect and maintain various parts. After the inspection and maintenance work is completed, the sliding ring 607 pulls out the limiting rod 609, rotates the second ladder 605 and the connecting shaft 604 to retract them, and then pushes the first ladder 601 back to the bottom of the slide rail 404 along the slide groove 603 to complete the storage of the maintenance structure 6.

[0043] In use, when installing the compressor 203, firstly, the second handwheel 406 is rotated, which drives the second screw 405 to rotate. Since the second screw 405 is threadedly connected to one of the drive frames 402, and the other drive frame 402 is slidably connected to the guide shaft 411, the two drive frames 402 move along the guide rail 401. The moving wheels 403 at the bottom of the drive frames 402 roll inside the guide rail 401, thereby adjusting the position of the drive frames 402. Then, [the process continues]. After the limiting structure 5 contacts the limiting position between the mounting plate 407 and the slide rail 404, the handle 506 is pulled, which in turn pulls the mounting plate 407. The rollers 410 on both sides of the mounting plate 407 roll on the slide rail 404, while the limiting shaft 409 slides in the limiting groove 408, causing the mounting plate 407 to move on the slide rail 404. When the entire mounting plate 407 is moved to its outermost position, the operator can install the compressor 203 on the mounting plate 407 with bolts. As the mounting plate 407 extends outward... The increased operating space makes the installation of compressor 203 easier and simpler. After installing compressor 203, move it to a suitable position so that the connecting pipe of compressor 203 is aligned with the pipe of evaporator 1, and the flange holes on the two pipes are aligned to facilitate the subsequent installation of fixing bolts. After alignment, operate the limit structure 5 to release the two levers 501, the first spring 505 returns to its original position, and then drives the two levers 501 to slide. The levers 501 drive the locking rod 502 to slide, and the locking rod 502 then engages with the locking hole 503 on the slide rail 404, thereby fixing the position of the mounting plate 407 and compressor 203. Then the pipes of compressor 203 can be connected. If it is necessary to contact the limit structure 5, the two levers 501 can be pinched. The levers 501 cause the locking rod 502 to disengage from the locking hole 503, thereby adjusting the position of mounting plate 407. The guide rod 504 improves the stability of the sliding of lever 501 and prevents the first spring 505 from deviating.

[0044] Then, the high-pressure liquid refrigerant is depressurized by a throttling device (a standard component of the refrigeration cycle) and enters the evaporator 1. In the evaporator 1, the liquid refrigerant absorbs heat from the chilled water and evaporates into a low-pressure gaseous refrigerant. At the same time, the temperature of the chilled water decreases, becoming the cold source for the air conditioning system. The compressor 203 is installed above the evaporator 1 via the calibration structure 4. During operation, it draws in the low-pressure gaseous refrigerant generated in the evaporator 1, compresses it, and transforms it into a high-pressure, high-temperature gaseous refrigerant. The guide rail 401, drive frame 402, and mounting plate 407 in the calibration structure 4 can adjust the position of the compressor 203 to ensure that it is aligned with the pipes of the evaporator 1, ensuring smooth refrigerant flow and preventing misalignment due to installation. Leakage or resistance loss caused by poor pressure: After the high-pressure, high-temperature gaseous refrigerant is discharged from the compressor 203, it enters the condenser 201. The condenser 201 removes heat through the cooling medium, cools and liquefies the refrigerant, and converts it into high-pressure liquid refrigerant. The high-pressure liquid refrigerant is then depressurized by the throttling device and enters the evaporator 1 to complete the cycle. During this stage, the gas-liquid separator 204 separates liquid impurities present in the refrigerant to ensure the purity of the refrigerant entering the subsequent stages and avoid affecting the evaporation efficiency. The intelligent control system integrated in the electrical cabinet 202 can automatically adjust the speed of the compressor 203 and the working state of the condenser 201 according to the load changes of the evaporator 1 to achieve "cooling on demand".

[0045] When it is necessary to agitate the chilled water inside the evaporator 1 to improve heat exchange efficiency, the motor 308 is started. The motor 308 drives the drive shaft 311 to rotate, and the drive shaft 311 drives the stirring shaft 302 to rotate via the insert rod 320. The stirring blades 303 on the stirring shaft 302 agitate the chilled water, promoting heat exchange between the cooling medium and the chilled water. When it is necessary to clean the scale inside the evaporator 1, first turn the first handwheel 309 to drive the first screw 305 to rotate. Since the first screw 305 is rotatably connected to the connecting frame 306, the connecting plate 307 moves on the fixed frame 304 with the guide column 321. Adjust the motor... The positions of 308 and drive shaft 311 are determined. The rotating ring 314 on the drive shaft 311 is separated from the fixed column 312. At the same time, the connecting hole 315 on the rotating ring 314 is inserted into the insertion post 319 on the fixed plate 318. Then, the motor 308 is started, and the motor 308 drives the drive shaft 311 to rotate. The drive shaft 311 drives the stirring shaft 302 to rotate. The stirring shaft 302 drives the fixed plate 318 to rotate. The fixed plate 318 drives the rotating ring 314 to rotate. The rotating ring 314 drives the scraper 317 to rotate through the connecting strip 316. The scraper 317 abuts against the inner wall of the inner sleeve 301 to clean the scale on the inner wall and discharge it with the flowing chilled water.

[0046] Finally, when equipment maintenance is required, first pull the first ladder 601 out of the slide groove 603 at the bottom of the slide rail 404, causing the rotating shaft 602 to slide in the slide groove 603. The rotating shaft 602 will fall at the L-shaped end of the slide groove 603, thus fixing the end position of the first ladder 601. Then rotate the first ladder 601 to unfold it, and then slide the slip ring 607. The slip ring 607 slides on the connecting shaft 604, compressing the second spring 608. The limiting rod 609 on the slip ring 607 separates from the limiting hole 610 on the first ladder 601. At this time, the second ladder 605 can be rotated to make the second... The ladder 605 drives the connecting shaft 604 to rotate to a suitable angle, and then the slip ring 607 is released. Under the action of the second spring 608, the limiting rod 609 is inserted into the limiting hole 610 to fix the position of the second ladder 605. The operator can then reach the top of the evaporator 1 through the first ladder 601 and the second ladder 605 to inspect and maintain various parts. After the inspection and maintenance work is completed, the sliding slip ring 607 pulls out the limiting rod 609, rotates the second ladder 605 and the connecting shaft 604 to retract, and then pushes the first ladder 601 back to the bottom of the slide rail 404 along the slide groove 603 to complete the storage of the maintenance structure 6.
