Description

Technical Field

[0001] This invention relates to the field of chiller technology, and more specifically to a chiller and method with leakage protection function. Background Technology

[0002] Nowadays, most refrigeration equipment used in production and daily life is water chiller. Water chillers are divided into air-cooled water chillers and water-cooled water chillers. Air-cooled water chillers have the advantages of small footprint and can be used immediately after placement. However, air-cooled water chillers are easily affected by the environment and have poor cooling effect. Water-cooled water chillers have the advantages of good cooling effect and are not affected by the environment. However, water-cooled water chillers require the installation of a water tower and occupy a larger area. Therefore, water-cooled water chillers are often used in large-scale industrial production.

[0003] For example, Chinese patent CN219868583U proposes a water-cooled screw chiller, including a condenser, an evaporator, a screw compressor, an electrical control box, a left support frame, and a right support frame. The right support frame is equipped with a mounting cover, which is connected to the side of the right support frame near the left support plate by a locking device. The screw compressor is located inside the mounting cover. The mounting cover is equipped with a heat dissipation component and heat dissipation holes. The heat dissipation component is located at the end of the mounting cover away from the right support frame, and the heat dissipation holes are located on one or both sides of the mounting cover. The left support frame is equipped with a mounting bracket, one end of which is connected to the top of the left support frame, and the other end is connected to the side of the mounting cover. The electrical control box is located on the side of the mounting bracket away from the mounting cover.

[0004] However, the aforementioned patent uses an external water tower to supply cooling water to the condenser during refrigeration, which may cause sludge from the water tower to accumulate inside the condenser, thus affecting the chiller's refrigeration efficiency. In use, the temperature around the evaporator inlet is higher than the temperature at the condenser inlet, resulting in uneven temperatures of the liquid inside the evaporator and condenser, which affects the chiller's refrigeration efficiency.

[0005] Based on this, the present invention designs a chiller and method with leakage protection function to solve the above problems. Summary of the Invention

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a chiller and method with leakage protection function.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A chiller with leakage protection function includes a base plate;

[0009] An evaporator and a condenser are fixedly connected to the upper left and right sides of the base plate, respectively.

[0010] Both the evaporator and the condenser are connected to the top of a cover locking assembly for opening the top of the evaporator or the condenser.

[0011] Both the evaporator and condenser are equipped with rotating ventilation heat exchange components to prevent sludge buildup inside the evaporator and condenser and to ensure uniform heating inside the evaporator and condenser.

[0012] A linkage compression assembly is fixedly connected to the front end of the base plate between the evaporator and the condenser. This assembly is used to compress the steam in the evaporator and simultaneously drive the two sets of rotating ventilation heat exchange components to rotate.

[0013] The upper end of the linkage compression assembly is connected to a pressure detector used to check the outlet air pressure of the linkage compression assembly and to determine whether the chiller is leaking refrigerant.

[0014] The rotating ventilation heat exchange assembly includes a rotating plate, a rotating shaft, ventilation heat exchange tubes, and a water deflector. The rotating plates are rotatably connected to the front and rear ends of both the evaporator and the condenser. There is a set of rotating shafts in both the evaporator and the condenser, and the front and rear ends of the rotating shafts pass through a set of rotating plates respectively. The rotating shafts are fixedly connected to the rotating plates. Several sets of ventilation heat exchange tubes are fixedly connected between the two sets of rotating plates in the evaporator and between the two sets of rotating plates in the condenser. The front and rear ends of the ventilation heat exchange tubes pass through the rotating plates and are fixedly connected to the rotating plates. Several sets of water deflectors are fixedly connected between the outer ends of the two sets of rotating plates in the evaporator and between the outer ends of the two sets of rotating plates in the condenser.

[0015] Furthermore, the front ends of the two sets of rotating shafts pass through the front sidewalls of the evaporator and condenser, respectively, and are fixedly connected to a linkage compression assembly.

[0016] Furthermore, the linkage compression assembly includes a motor, a support frame, an Ω-shaped rotating rod, a transmission assembly, a linkage push rod, a compression tube, and a compression piston. The motor is fixedly connected to the top of the base plate between the evaporator and the condenser. The support frame is fixedly connected to the top of the base plate in front of the motor. The output end of the motor passes through the rear side wall of the support frame and is fixedly connected to the Ω-shaped rotating rod. The front end of the Ω-shaped rotating rod passes through the front side wall of the support frame and is fixedly connected to the transmission assembly. The middle crossbar of the Ω-shaped rotating rod is rotatably connected to the linkage push rod. The top of the linkage push rod is rotatably connected to the compression piston through a hinge seat. The top of the support frame is fixedly connected to the compression tube. The compression piston slides inside the compression tube. The Ω-shaped rotating rod is connected to two sets of rotating shafts through the transmission assembly.

[0017] Furthermore, a pressure detector is fixedly connected to the upper end of the compressor pipe outlet, the compressor pipe inlet is connected to the evaporator outlet, and the compressor pipe outlet is connected to the condenser inlet.

[0018] Furthermore, the lid opening and locking assembly includes a lid opening assembly and a locking assembly. The lid opening assembly is inserted into the upper end of both the evaporator and the condenser. The front and rear ends of the two sets of lid opening assemblies are fixedly connected to the locking assembly. The ends of the two sets of locking assemblies on one set of lid opening assemblies that are far apart from each other are threaded onto the evaporator or the condenser.

[0019] Furthermore, the opening assembly includes a plug cover, a telescopic sliding cover, a first slot, a sliding groove, and a second slot. The evaporator and condenser are provided with second slots at both ends. The evaporator and condenser are provided with first slots in the middle of the left and right side walls. The evaporator and condenser are each provided with a set of plug covers at the top. The lower left and right sides of the plug cover are inserted into the first slot. The plug cover is provided with sliding grooves at both ends. A set of telescopic sliding covers is slidably connected in each sliding groove. The ends of the telescopic sliding covers that are far apart from each other are inserted into the second slot.

[0020] Furthermore, the locking assembly includes a semi-annular protrusion and a threaded rod. The two sets of telescopic sliding covers on the same set of plug covers are fixedly connected to the middle of the outer wall. The upper ends of the front and rear side walls of the evaporator and condenser are each provided with several sets of threaded rods. The threaded rods pass through the side wall of the evaporator or condenser and the semi-annular protrusion and are threadedly connected to the semi-annular protrusion. The threaded rods are rotatably connected to the evaporator and condenser.

[0021] To better achieve the objectives of this invention, this invention also provides a method for using a chiller with leakage protection function, comprising the following steps:

[0022] Step 1: When the chiller is working, refrigerant is introduced into the evaporator and coolant is introduced into the condenser. At this time, the linkage compression assembly is started. The linkage compression assembly drives two sets of rotating shafts at the same time. The rotating shafts drive the rotating plates to rotate. The rotating plates drive the ventilation heat exchange tubes and the water deflector to rotate. The ventilation heat exchange tubes rotate and contact the liquid at various positions inside the condenser or evaporator. When the water deflector rotates, it continuously lifts the water and sludge at the bottom of the evaporator or condenser to the top and then sprinkles it down from the top.

[0023] Step 2: When gas compression is required in the evaporator, start the motor. The motor drives the Ω-shaped rotor to rotate. The Ω-shaped rotor, through the transmission assembly, simultaneously drives two sets of rotating ventilation heat exchange components to rotate. The Ω-shaped rotor drives the lower end of the linkage push rod to rotate around the output end of the motor. The linkage push rod, through the hinge seat, drives the compression piston to move up and down inside the compression tube. When the compression piston moves to the lowest point, it blocks the outlet of the compression tube and sends the gas in the evaporator into the compression tube above the compression piston through the inlet. When the gas delivery is complete, block the inlet of the compression tube. At this time, start the motor. The motor drives the compression piston to move upward through the Ω-shaped rotor and the linkage push rod. At this time, the compression piston compresses the gas inside the compression tube, thereby forming high-temperature and high-pressure gas inside the compression tube. At this time, open the inlet of the compression tube and send the high-temperature and high-pressure gas inside the compression tube into the condenser through the pressure detector. The pressure detector detects the gas pressure at the outlet of the compression tube. When the gas inside the compression tube is completely released, continue to run the motor. The motor drives the compression piston to move downward through the linkage push rod, and repeat the above operation.

[0024] Step 3: When repairs are needed inside the evaporator and condenser, rotate the threaded rod. The threaded rod, through the semi-annular protrusion, drives the telescopic sliding cover to move closer to the insert cover under the limiting guidance of the second slot and the slide groove. When the telescopic sliding cover is completely disengaged from the second slot, pull the insert cover upwards. At this time, the insert cover drives the telescopic sliding cover upwards until the insert cover disengages from the first slot. When the repair is complete, re-insert the lower end of the insert cover into the first slot. At this time, pull the telescopic sliding cover and the semi-annular protrusion away from the insert cover and let the threaded rod pass through the semi-annular protrusion. Then rotate the threaded rod. The threaded rod, through the semi-annular protrusion, drives the telescopic sliding cover to move away from the insert cover and insert it into the second slot.

[0025] The present invention has the following technical effects:

[0026] When the chiller is working, refrigerant is introduced into the evaporator and coolant into the condenser. At this time, the linkage compression assembly is activated, which simultaneously drives two sets of rotating shafts. The rotating shafts drive rotating plates, which in turn drive the venting heat exchange tubes and the water deflector to rotate. The rotation of the venting heat exchange tubes allows them to contact the liquid at various locations inside the condenser or evaporator, thus preventing temperature differences between the venting heat exchange tubes near the inlet and those elsewhere. As the water deflector rotates, it continuously lifts water and sludge from the lower end of the evaporator or condenser to the upper end and then sprays it down. This prevents sludge accumulation at the lower end of the evaporator and condenser and keeps the liquid inside the evaporator and condenser constantly agitated, resulting in uniform heating of all venting heat exchange tubes and enhancing the efficiency of the chiller.

[0027] This invention activates the motor when gas compression within the evaporator is required. The motor drives an Ω-shaped rotor to rotate, which in turn drives two sets of rotating ventilation and heat exchange components via a transmission assembly. This eliminates the need for additional drive components, saving costs. The Ω-shaped rotor drives the lower end of a linkage push rod to rotate around the motor's output end. The linkage push rod, via a hinged seat, drives a compression piston to move up and down inside the compression tube. When the compression piston reaches its lowest point, it seals the outlet of the compression tube and sends gas from the evaporator into the compression tube above the piston through the inlet. Once the gas delivery is complete, the inlet of the compression tube is sealed, and the motor is activated. The motor then... The Ω-shaped rotating rod and the linkage push rod drive the compression piston upwards. At this time, the compression piston compresses the gas inside the compression tube, creating high-temperature, high-pressure gas inside the tube. The air inlet of the compression tube is then opened, allowing the high-temperature, high-pressure gas inside the tube to be sent into the condenser via a pressure detector. The pressure detector monitors the gas pressure at the outlet of the compression tube. Normally, the gas pressure inside the evaporator and the compression piston position remain constant, resulting in a constant gas pressure at the outlet of the compression tube. When the pressure detector detects a change in the gas pressure at the outlet of the compression tube, it indicates a refrigerant leak somewhere in the chiller. This allows for immediate detection of the refrigerant leak, enabling timely repairs and minimizing losses. After the internal gas is released, the motor continues to run. The motor drives the compression piston downwards via a linkage push rod. This process is repeated to achieve repeated compression of the gas inside the evaporator. This allows a standard motor to achieve repeated compression of the gas inside the evaporator, eliminating the need for a cylinder or a reversible motor, thus saving costs. Furthermore, when repairs are needed inside the evaporator and condenser, rotating the threaded rod causes it to move the telescopic sliding cover towards the insert cover, guided by the second slot and the sliding groove via a semi-annular protrusion. When the telescopic sliding cover is completely disengaged from the second slot, pulling the insert cover upwards causes it to move the telescopic sliding cover upwards until it disengages from the first slot, thus achieving… The opening of the upper end of the evaporator and condenser makes the repair of the ventilation heat exchange tubes more convenient. When the ventilation heat exchange tubes leak, it is not necessary to remove each tube one by one for repair. Simply open the upper end of the evaporator and condenser to repair directly, thus realizing simple repair of the ventilation heat exchange tubes. After the repair is completed, re-insert the lower end of the plug into the first slot. At this time, pull the telescopic sliding cover and the semi-circular protrusion away from the plug and let the threaded rod pass through the semi-circular protrusion. Then rotate the threaded rod. The threaded rod drives the telescopic sliding cover away from the plug and inserts it into the second slot through the semi-circular protrusion, thus completing the sealing and locking of the upper end of the evaporator and condenser.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0039] The present invention will be further described below with reference to embodiments.

[0040] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0041] Example 1

[0042] Please refer to the instruction manual appendix. Figure 1-5 A chiller with leakage protection function includes a base plate 1;

[0043] An evaporator and a condenser are fixedly connected to the upper left and right sides of the base plate 1, respectively;

[0044] Both the evaporator and the condenser are connected to the upper end of a cover-opening locking assembly 4 for opening the upper end of the evaporator or the condenser;

[0045] Both the evaporator and condenser are equipped with rotating ventilation heat exchange components 2 to prevent sludge buildup inside the evaporator and condenser and to ensure uniform heating inside the evaporator and condenser.

[0046] A linkage compression assembly 3 is fixedly connected to the front end of the base plate 1 between the evaporator and the condenser. This assembly is used to compress the steam in the evaporator and simultaneously drive the two sets of rotating ventilation heat exchange assemblies 2 to rotate.

[0047] The upper end of the linkage compression assembly 3 is connected to a pressure detector 5, which is used to check the outlet air pressure of the linkage compression assembly 3 and to determine whether the chiller is leaking refrigerant by measuring the air pressure.

[0048] An expansion valve 6 is fixedly connected to the rear end of the base plate 1 between the evaporator and the condenser to disperse and spray the liquid in the condenser into the evaporator.

[0049] The rotating ventilation heat exchange assembly 2 includes a rotating plate 21, a rotating shaft 22, ventilation heat exchange tubes 23, and a water deflector 24. The rotating plates 21 are rotatably connected to the front and rear ends of the evaporator and the condenser. There is a set of rotating shafts 22 in both the evaporator and the condenser, and the front and rear ends of the rotating shafts 22 pass through a set of rotating plates 21 respectively. The rotating shafts 22 are fixedly connected to the rotating plates 21. Several sets of ventilation heat exchange tubes 23 are fixedly connected between the two sets of rotating plates 21 in the evaporator and between the two sets of rotating plates 21 in the condenser. The front and rear ends of the ventilation heat exchange tubes 23 pass through the rotating plates 21 and are fixedly connected to the rotating plates 21. Several sets of water deflectors 24 are fixedly connected between the outer ends of the two sets of rotating plates 21 in the evaporator and between the outer ends of the two sets of rotating plates 21 in the condenser. The front ends of the two sets of rotating shafts 22 pass through the front sidewalls of the evaporator and the condenser respectively and are fixedly connected to the linkage compression assembly 3.

[0050] When the chiller is working, refrigerant is introduced into the evaporator and coolant into the condenser. At this time, the linkage compression assembly 3 is activated, which simultaneously drives two sets of rotating shafts 22. The rotating shafts 22 drive the rotating plate 21 to rotate, and the rotating plate 21 drives the venting heat exchange tube 23 and the water deflector 24 to rotate. The rotation of the venting heat exchange tube 23 allows it to contact the liquid at various locations inside the condenser or evaporator, thus preventing temperature differences between the venting heat exchange tube 23 near the inlet and other locations. When the water deflector 24 rotates, it continuously lifts water and sludge from the lower end of the evaporator or condenser to the upper end and then sprinkles it down. This prevents sludge accumulation at the lower end of the evaporator and condenser and keeps the liquid inside the evaporator and condenser agitated, ensuring that all venting heat exchange tubes 23 are heated evenly and enhancing the chiller's efficiency.

[0051] Example 2

[0052] like Figure 1-7As shown, in a preferred embodiment of the present invention, the linkage compression assembly 3 includes a motor 31, a support frame 32, an Ω-shaped rotating rod 33, a transmission assembly 34, a linkage push rod 35, a compression pipe 36, and a compression piston 37. The motor 31 is fixedly connected to the top of the base plate 1 between the evaporator and the condenser. The support frame 32 is fixedly connected to the top of the base plate 1 in front of the motor 31. The output end of the motor 31 passes through the rear sidewall of the support frame 32 and is fixedly connected to the Ω-shaped rotating rod 33. The front end of the Ω-shaped rotating rod 33 passes through the front sidewall of the support frame 32 and is fixedly connected to the transmission assembly 34. In component 34, the middle crossbar of the Ω-shaped rotating rod 33 is rotatably connected to the linkage push rod 35. The top of the linkage push rod 35 is rotatably connected to the compression piston 37 through the hinge seat. The top of the support frame 32 is fixedly connected to the compression tube 36. The compression piston 37 slides inside the compression tube 36. The Ω-shaped rotating rod 33 is connected to two sets of rotating shafts 22 through the transmission component 34. The upper end of the outlet pipe of the compression tube 36 is fixedly connected to the pressure detector 5. The inlet of the compression tube 36 is connected to the outlet of the evaporator. The outlet of the compression tube 36 is connected to the inlet of the condenser.

[0053] When gas compression is required in the evaporator, motor 31 is started. Motor 31 drives the Ω-shaped rotating rod 33 to rotate. The Ω-shaped rotating rod 33, through the transmission assembly 34, simultaneously drives the two sets of rotating ventilation heat exchange components 2 to rotate, thus achieving the rotation of the two sets of rotating ventilation heat exchange components 2 without the need for additional drive components, saving costs. The Ω-shaped rotating rod 33 drives the lower end of the linkage push rod 35 to rotate around the output end of motor 31. The linkage push rod 35, through the hinge seat, drives the compression piston 37 to move up and down inside the compression tube 36. When the compression piston 37 moves to the lowest point, it blocks the outlet of the compression tube 36 and sends the gas in the evaporator into the compression tube 36 above the compression piston 37 through the inlet. When the gas delivery is complete, the inlet of the compression tube 36 is blocked. At this time, motor 31 is started. Motor 31, through the Ω-shaped rotating rod 33 and the linkage push rod 35, drives the compression piston 37 to move upward. At this time, the compression piston 37 compresses the gas inside the compression tube 36, thereby compressing the gas. High-temperature, high-pressure gas forms inside pipe 36. At this time, the air inlet of compression pipe 36 is opened, and the high-temperature, high-pressure gas inside compression pipe 36 is sent into the condenser through pressure detector 5. Pressure detector 5 detects the gas pressure at the outlet of compression pipe 36. Under normal circumstances, the gas pressure inside the evaporator remains unchanged and the compression piston 37 remains unchanged, so the gas pressure at the outlet of compression pipe 36 remains unchanged. When pressure detector 5 detects a change in the gas pressure at the outlet of compression pipe 36, it proves that there is a refrigerant leak somewhere in the chiller. This allows the refrigerant leak to be observed immediately, so that it can be repaired immediately, reducing losses. When the gas inside compression pipe 36 is released, motor 31 continues to run. Motor 31 drives compression piston 37 downward through linkage push rod 35. At this time, the above operation is repeated, which realizes the repeated compression of gas inside the evaporator. This allows ordinary motors to achieve repeated compression of gas inside the evaporator without the need for cylinders or forward and reverse motors, saving costs.

[0054] Example 2

[0055] like Figure 1-7 As shown, in a preferred embodiment of the present invention, the lid opening and locking assembly 4 includes a lid opening assembly 41 and a locking assembly 42. The lid opening assembly 41 is inserted into the upper end of both the evaporator and the condenser. The locking assembly 42 is fixedly connected to both the front and rear ends of the two sets of lid opening assemblies 41. The ends of the two sets of locking assemblies 42 on one set of lid opening assembly 41 that are far apart from each other are threaded to the evaporator or the condenser.

[0056] The opening assembly 41 includes a plug cover 411, a telescopic sliding cover 412, a first slot 413, a sliding groove 414, and a second slot 415. The evaporator and condenser are provided with second slots 415 at both ends. The evaporator and condenser are provided with first slots 413 in the middle of the left and right side walls. The evaporator and condenser are provided with a set of plug covers 411 at the top. The lower left and right sides of the plug cover 411 are inserted into the first slot 413. The plug cover 411 is provided with sliding grooves 414 at both ends. A set of telescopic sliding covers 412 is slidably connected in the sliding grooves 414. The ends of the telescopic sliding covers 412 that are far apart from each other are inserted into the second slots 415.

[0057] The locking assembly 42 includes a semi-annular protrusion 421 and a threaded rod 422. The semi-annular protrusion 421 is fixedly connected to the middle of the outer wall of the two sets of telescopic sliding covers 412 on the same set of plug covers 411. Several sets of threaded rods 422 are provided on the upper ends of the front and rear side walls of the evaporator and the condenser. The threaded rods 422 pass through the side wall of the evaporator or the condenser and the semi-annular protrusion 421 and are threadedly connected to the semi-annular protrusion 421. The threaded rods 422 are rotatably connected to the evaporator and the condenser.

[0058] When repairs are needed inside the evaporator and condenser, the threaded rod 422 is rotated. The threaded rod 422, via the semi-annular protrusion 421, drives the telescopic sliding cover 412 to move towards the insert cover 411 under the limiting guidance of the second slot 415 and the slide groove 414. When the telescopic sliding cover 412 is completely disengaged from the second slot 415, the insert cover 411 is pulled upwards. At this time, the insert cover 411 drives the telescopic sliding cover 412 upwards until the insert cover 411 disengages from the first slot 413, thus opening the upper part of the evaporator and condenser. This makes repairs to the venting heat exchange tube 23 more convenient. When the venting heat exchange tube 23 leaks, it is not necessary to remove each tube individually. Repairing the heat pipe 23 only requires opening the upper end of the evaporator and condenser for direct repair, thus achieving simple repair of the venting heat exchanger 23. After repair, the lower end of the plug 411 is reinserted into the first slot 413. At this time, the telescopic sliding cover 412 and the semi-annular protrusion 421 are pulled away from the plug 411 and the threaded rod 422 passes through the semi-annular protrusion 421. Then, the threaded rod 422 is rotated, and the threaded rod 422 drives the telescopic sliding cover 412 to move away from the plug 411 through the semi-annular protrusion 421 and inserts it into the second slot 415, thereby completing the sealing and locking of the upper end of the evaporator and condenser.

[0059] Example 3

[0060] like Figure 1-7 As shown, a method of using a chiller with leakage protection function includes the following steps:

[0061] Step 1: When the chiller is working, refrigerant is introduced into the evaporator and coolant is introduced into the condenser. At this time, the linkage compression assembly 3 is started. The linkage compression assembly 3 simultaneously drives two sets of rotating shafts 22. The rotating shafts 22 drive the rotating plate 21 to rotate. The rotating plate 21 drives the ventilation heat exchange tube 23 and the water deflector 24 to rotate. The ventilation heat exchange tube 23 rotates and contacts the liquid at various positions inside the condenser or evaporator. When the water deflector 24 rotates, it continuously lifts the water and sludge at the bottom of the evaporator or condenser to the top and then sprinkles it down from the top.

[0062] Step 2: When gas compression is required in the evaporator, start motor 31. Motor 31 drives Ω-shaped rotating rod 33 to rotate. Ω-shaped rotating rod 33, through transmission assembly 34, simultaneously drives two sets of rotating ventilation heat exchange assemblies 2 to rotate. Ω-shaped rotating rod 33 drives the lower end of linkage push rod 35 to rotate around the output end of motor 31. Linkage push rod 35, through hinge seat, drives compression piston 37 to move up and down inside compression tube 36. When compression piston 37 moves to its lowest point, it seals the outlet of compression tube 36 and sends gas from the evaporator into the compression tube 36 above compression piston 37 through the inlet. When gas delivery is complete, the inlet of compression tube 36 is sealed. At this time, the motor 31 is started. The motor 31 drives the compression piston 37 to move upward through the Ω-shaped rotating rod 33 and the linkage push rod 35. At this time, the compression piston 37 squeezes the gas inside the compression tube 36, thereby forming a high temperature and high pressure gas inside the compression tube 36. At this time, the air inlet of the compression tube 36 is opened, and the high temperature and high pressure gas inside the compression tube 36 is sent into the condenser through the pressure detector 5. The pressure detector 5 detects the gas pressure at the outlet of the compression tube 36. When the gas inside the compression tube 36 is completely released, the motor 31 continues to run. The motor 31 drives the compression piston 37 to move downward through the linkage push rod 35, and the above operation is repeated.

[0063] Step 3: When repairs are needed inside the evaporator and condenser, rotate the threaded rod 422. The threaded rod 422, through the semi-annular protrusion 421, drives the telescopic sliding cover 412 to move towards the insert cover 411 under the limiting guidance of the second slot 415 and the slide groove 414. When the telescopic sliding cover 412 is completely disengaged from the second slot 415, pull the insert cover 411 upward. At this time, the insert cover 411 drives the telescopic sliding cover 412 upward until the insert cover 411 disengages from the first slot 413. When the repair is completed, re-insert the lower end of the insert cover 411 into the first slot 413. At this time, pull the telescopic sliding cover 412 and the semi-annular protrusion 421 away from the insert cover 411 and let the threaded rod 422 pass through the semi-annular protrusion 421. Then rotate the threaded rod 422.

6. A method of using a chiller with leakage protection function as described in claim 5, characterized in that, Includes the following steps: Step 1: When the chiller is working, refrigerant is introduced into the evaporator and coolant is introduced into the condenser. At this time, the linkage compression assembly (3) is started. The linkage compression assembly (3) drives two sets of rotating shafts (22) at the same time. The rotating shafts (22) drive the rotating plate (21) to rotate. The rotating plate (21) drives the ventilation heat exchange tube (23) and the water deflector (24) to rotate. The ventilation heat exchange tube (23) rotates and contacts the liquid at various positions inside the condenser or evaporator. When the water deflector (24) rotates, the water and sludge at the bottom of the evaporator or condenser are continuously lifted to the top and then sprinkled down from the top. Step 2: When it is necessary to compress the gas in the evaporator, start the motor (31). The motor (31) drives the Ω-shaped rotating rod (33) to rotate. The Ω-shaped rotating rod (33) drives the two sets of rotating ventilation heat exchange components (2) to rotate simultaneously through the transmission assembly (34). The Ω-shaped rotating rod (33) drives the lower end of the linkage push rod (35) to rotate around the output end of the motor (31). The linkage push rod (35) drives the compression piston (37) to move up and down inside the compression tube (36) through the hinge seat. When the compression piston (37) moves to the lowest point, it blocks the gas outlet of the compression tube (36) and sends the gas in the evaporator into the compression tube (36) above the compression piston (37) through the gas inlet. When the gas delivery is completed, the compression tube (36) is blocked. 6) Air inlet. At this time, the motor (31) is started. The motor (31) drives the compression piston (37) to move upward through the Ω-shaped rotating rod (33) and the linkage push rod (35). At this time, the compression piston (37) squeezes the gas inside the compression tube (36), thereby forming a high temperature and high pressure gas inside the compression tube (36). At this time, the air inlet of the compression tube (36) is opened, and the high temperature and high pressure gas inside the compression tube (36) is sent into the condenser through the pressure detector (5). The pressure detector (5) detects the gas pressure at the outlet of the compression tube (36). When the gas inside the compression tube (36) is released, the motor (31) continues to run. The motor (31) drives the compression piston (37) to move downward through the linkage push rod (35). Step 3: When it is necessary to repair the inside of the evaporator and condenser, rotate the threaded rod (422). The threaded rod (422) drives the telescopic sliding cover (412) to move towards the insert cover (411) under the limiting guidance of the second slot (415) and the slide groove (414). When the telescopic sliding cover (412) is completely disengaged from the second slot (415), pull the insert cover (411) upward. At this time, the insert cover (411) drives the telescopic sliding cover (412) to move upward until the insert cover (411) disengages from the first slot. When the repair of the slot (413) is completed, the lower end of the plug cover (411) is re-inserted into the first slot (413). At this time, the telescopic sliding cover (412) and the semi-annular protrusion (421) are pulled away from the plug cover (411) and the threaded rod (422) passes through the semi-annular protrusion (421). At this time, the threaded rod (422) is rotated. The threaded rod (422) drives the telescopic sliding cover (412) to move away from the plug cover (411) through the semi-annular protrusion (421) and inserts it into the second slot (415).
