Description

Technical Field

[0001] The present invention relates to the technical field of water chillers, and in particular to an air suspension water chiller with a multi-compressor structure. Background Art

[0002] A chiller is a refrigeration unit for air conditioning, which achieves the cooling effect through a compressor and a cooling medium. The air-suspended compressor chiller is mainly composed of an air-suspended centrifugal compressor, a condenser, an evaporator, an air supply structure system, a motor cooling system and related pipelines, and performs a refrigeration cycle through heat exchange. However, most of the existing chillers only have one compressor in use. When the compressor fails or is damaged for maintenance and replacement, the chiller can only be shut down for maintenance. Moreover, when the compressor is damaged, the chiller will stop and cannot continue to operate, which will affect the operation of the cooling system and make it impossible to use it, resulting in an inability to cool down or produce. Summary of the invention

[0003] The object of the present invention is to provide an air suspension chiller with a multi-compressor structure to solve the problem in the background art that the chiller can only be shut down when a fault occurs.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an air-suspended chiller with a multi-compressor structure, including an air-suspended chiller with a multi-compressor structure, including a mounting base plate, the mounting base plates are fixedly mounted on both ends of a condenser, and partitions are respectively arranged at both ends of the condenser, a connecting mounting plate is fixedly mounted on the outer surface of the mounting base plate, and an evaporator is respectively installed on the connecting mounting plate, and partitions are fixedly mounted on both ends of the evaporator, a control cabinet is fixedly mounted on the outer surface of the condenser, and a plate-type heat dissipation pipe is fixedly mounted inside one end of the control cabinet, one end of the plate-type heat dissipation pipe is connected to the condenser, and the other end of the plate-type heat dissipation pipe is connected to the evaporator, and an electric controller is fixedly mounted on one end of the plate-type heat dissipation pipe located inside the control cabinet, characterized in that two air-suspended compressors are fixedly mounted on the outer surface of the evaporator, a multi-station design is provided between the evaporator and the condenser, and the working power of the chiller can be adjusted through the multi-station design, and the chiller can still operate independently in the event of a fault, and can be conveniently repaired and maintained without stopping.

[0005] Preferably, the multi-station design includes: a discharge pipe, which is fixedly installed at one end of the air suspension compressor, and an inlet pipe is fixedly installed on the outer surface of one end of the air suspension compressor, the discharge pipes are respectively connected to the condensers, and the two inlet pipes are respectively connected to the evaporators, and the diameter of the evaporator is larger than the diameter of the condenser.

[0006] By adopting the above technical solution, through the design of two condensers and air suspension compressors, the chiller can provide greater refrigeration capacity to adapt to different load requirements during operation, and if one air suspension compressor fails, the other air suspension compressor can still operate, thereby reducing the risk of system shutdown. A single air suspension compressor can be maintained and replaced while the system is running without causing a significant impact on the entire system, thereby improving reliability during operation.

[0007] Preferably, a stator is fixedly installed inside the air suspension compressor, air bearing assemblies are fixedly installed at both ends inside the air suspension compressor, and the air bearing assemblies are located on both sides of the stator, a rotor assembly is rotatably installed inside the air suspension compressor, and the rotor assembly passes through the stator, and a high-efficiency ribbed heat dissipation pipe is opened inside the shell of the air suspension compressor, and one end of the high-efficiency ribbed heat dissipation pipe is connected to the inlet pipe, and the other end of the high-efficiency ribbed heat dissipation pipe is connected to one end of the exhaust pipe.

[0008] By adopting the above technical solution, an air bearing assembly is used inside the air suspension compressor to support the rotor assembly. The air bearing assembly is located inside the air suspension compressor and surrounds the rotor assembly to provide stable support for the rotor assembly, thereby fundamentally eliminating mechanical friction, so that the air suspension compressor does not need lubricating oil and realizes an air suspension structure. When the air suspension compressor is running, the air bearing assembly is used to put the rotor assembly in a non-contact, frictionless suspension state. At the same time, the setting of the high-efficiency ribbed heat dissipation pipeline can increase the heat exchange efficiency by increasing the heat exchange area, and reduce the resistance of the fluid when flowing inside the high-efficiency ribbed heat dissipation pipeline. The rotor assembly is made of permanent magnetic material. When the stator is supplied with alternating current to generate a rotating magnetic field, the rotor assembly will be driven to rotate at high speed, and the power supply frequency and voltage of the air suspension compressor will be controlled by the frequency converter, so that the compressor load can be accurately adjusted within the range of 10%-100%. According to the actual load situation, the air suspension compressor can be controlled to automatically start and rotate in sequence, thereby achieving the purpose of energy saving and extending the life of the equipment, improving the performance of the air suspension compressor and the refrigeration effect of the entire chiller, simplifying the overall structure, and avoiding maintenance problems caused by lubricating oil, such as replacing lubricating oil and oil filter.

[0009] Preferably, a block-shaped protrusion is provided at one end of the connecting mounting plate close to the mounting base plate, and the outer surface of the mounting base plate is engaged with the connecting mounting plate, and the connecting mounting plate and the mounting base plate are fixed with screws, and the connecting mounting plate is located between the mounting base plates.

[0010] By adopting the above technical solution, the block-shaped protrusions of the connecting mounting plate can be used to improve the support of the connecting mounting plate when it is placed, and the lateral support force of the connecting mounting plate on the mounting base plate can be improved, so that the mounting base plate and the connecting mounting plate can be connected and fixed more stably.

[0011] Preferably, a flexible connection mechanism is provided between the air-suspended compressor and the condenser and the evaporator, and the flexible connection mechanism comprises: a rubber shock-absorbing pad, the rubber shock-absorbing pad is fixedly installed between the evaporator and the air-suspended compressor, and a first connecting soft pipe is fixedly installed at the connection between the air-suspended compressor and the exhaust pipe, and a second connecting soft pipe is fixedly installed between the evaporator and the inlet pipe.

[0012] By adopting the above technical solution, the vibration generated during the operation of the air suspension compressor can be reduced by the rubber shock-absorbing pad, and the vibration can be prevented from being transmitted to the outside through the exhaust pipe and the inlet pipe through the first connecting soft pipe and the second connecting soft pipe, so that the vibration generated during the operation of the air suspension compressor will not be transmitted to the evaporator, the connecting mounting plate, the mounting base plate and other components, thereby reducing the looseness between components caused by vibration and reducing leakage caused by looseness due to vibration.

[0013] Preferably, end covers are fixedly installed on one end side surface of the condenser and the evaporator respectively, and heat exchange pipes are installed through the inside of the condenser and the evaporator, and the heat exchange pipes are divided into upper and lower parts inside the condenser and the evaporator. Partitions are provided at one end of the condenser and the evaporator away from the end covers, the outer surface of the heat exchange pipe is uniformly provided with block-shaped protrusions, and the inside of the heat exchange pipe is uniformly provided with internal spiral patterns.

[0014] By adopting the above technical scheme, the block-shaped protrusions are evenly arranged on the outer surface of the heat exchange pipe, so that the area of ​​the heat exchange pipe during heat exchange can be larger, so that the heat exchange pipe can condense and evaporate to the maximum extent, and through the internal spiral texture inside the heat exchange pipe, the cooling water and the chilled water can exchange heat to the maximum extent when passing through the heat exchange pipe, and the cooling water and the chilled water can rotate and move along the internal spiral texture in the heat exchange pipe, thereby extending the movement time of the cooling water and the chilled water in the heat exchange pipe, so that the chilled water and the cooling water can better exchange heat when passing through the condenser and the evaporator.

[0015] Preferably, a second baffle cover is fixedly installed on the outer surface of one end of the condenser away from the end cover, a first baffle cover is fixedly installed on the outer surface of one end of the evaporator away from the end cover, and the outer surfaces of the first baffle cover and the second baffle cover are respectively provided with filtering mechanisms, and the filtering mechanism includes: a second baffle cover, a second flow meter is fixedly installed on the outer surface of one end of the second baffle cover, a second solenoid valve is fixedly installed on the end of the second baffle cover away from the second flow meter, a first flow meter is fixedly installed on the outer surface of one end of the first baffle cover, a first solenoid valve is fixedly installed on the outer surface of one end of the first baffle cover away from the first flow meter, and filter mesh members are threadedly installed on the outer surfaces of the first solenoid valve and the second solenoid valve.

[0016] By adopting the above technical scheme, when cooling water and chilled water pass through the first baffle cover, the baffle at one end of the condenser and the evaporator can separate the outlets of the injected cooling water and the chilled water, and enable the cooling water and the chilled water to pass through the heat exchange pipe and transfer through the end cover, and be sent out from the heat exchange pipe at the lower end of the condenser and the evaporator. When the end covers, the first baffle cover and the second baffle cover arranged at both ends of the condenser and the evaporator are removed, the heat exchange pipe inside the condenser and the evaporator can be conveniently cleaned. At the same time, the cooling water and the chilled water can be controlled to pass through the condenser and the evaporator through the first solenoid valve and the second solenoid valve, and the impurities generated in the cooling water and the chilled water can be filtered through the filter mesh on the outer surface of the first solenoid valve and the second solenoid valve. The flow rate of the discharged cooling water and the chilled water can be measured by the first flow meter and the second flow meter arranged on the outer surface of the first baffle cover and the second baffle cover. When the first flow meter and the second flow meter detect that the flow rate has dropped, the filter mesh can be removed and cleaned to maintain the flow rate of cooling water and chilled water passing through without affecting the heat exchange efficiency of the condenser and the evaporator.

[0017] Preferably, two flash evaporators are fixedly mounted on the outer surface of the condenser, and the flash evaporators are respectively connected to the condenser and the evaporator; air supply pipes are fixedly mounted on the outer surfaces of the two flash evaporators, and the air supply pipes are connected to the inlet pipeline.

[0018] By adopting the above technical solution, in the refrigeration cycle, after the refrigerant is compressed and condensed by the air suspension compressor, the high-temperature and high-pressure refrigerant will pass through the flash evaporator and use the sudden drop in pressure to cause a part of the refrigerant to quickly evaporate into gas. Then the remaining refrigerant will be sent back to the evaporator, and the evaporated gas will enter the air suspension compressor through the air supply pipe for air supply, thereby improving the working efficiency of the air suspension compressor and reducing the energy consumption of the air suspension compressor.

[0019] Preferably, mounting feet are fixedly installed on the outer surfaces of both ends of the mounting base plate, and pads are slidably installed inside the mounting feet. A sliding extrusion mechanism is provided between the pad and the mounting feet. The height and horizontality of the chiller can be conveniently adjusted through the sliding extrusion mechanism, so that unnecessary vibration and noise can be reduced when the chiller is in use, thereby ensuring the normal operation of the chiller and increasing its service life.

[0020] By adopting the above technical solution, the height and levelness of the chiller can be easily adjusted, so that unnecessary vibration and noise can be reduced when the chiller is in use, thereby ensuring the normal operation and service life of the chiller.

[0021] Preferably, the sliding extrusion mechanism includes: a tensioning bolt, which is threadedly connected to the mounting base plate and the mounting foot, and an inclined top tightening block is slidably installed inside the mounting foot, and the inclined top tightening block is rotatably connected to the tensioning bolt, the outer surface of the inclined top tightening block is fitted with the outer surface of the cushion block, a limiting bolt is inserted and installed on the outer surface of the mounting foot, and the limiting bolt is slidably connected to the cushion block, and a threaded hole is provided on the outer surface of the cushion block, the outer surface of the limiting bolt is fitted with the outer surface of the inclined top tightening block, a fixing nut is threadedly installed on the outer surface of the tensioning bolt, and the outer surface of the fixing nut is fitted with the outer surface of the mounting base plate, and a rubber anti-slip shock-absorbing plate is fitted and fixed to the outer surface of the cushion block.

[0022] By adopting the above technical solution, the inclined top tightening block can be moved inside the installation foot by rotating the tightening bolt, and the pad block can be pushed by the movement of the inclined top tightening block to adjust the movement distance and height of the pad block in the installation foot, so as to facilitate the adjustment of the horizontality of the water-cooled unit. After that, the fixing nut can be tightened to fix the position of the tightening bolt. At the same time, the pad block and the inclined top tightening block will not shake or fall off at will inside the installation foot by the limit bolt, and the pad block can be fixed by tightening the limit bolt. At the same time, when the water-cooled unit needs to be fixed to the ground, it is only necessary to replace the limit bolt with a smaller size to connect and fix the limit bolt to the bolt hole reserved on the ground, which is convenient for fixed installation and non-fixed installation.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: the air suspension chiller with a multi-compressor structure:

[0024] 1. Through two condensers and an air suspension compressor, the refrigerant in the evaporator can be evaporated and then extracted, compressed and discharged into the condenser by the air suspension compressor, so that the two air suspension compressors can work together individually or alternately, which can provide a greater refrigeration capacity for the refrigeration system and can adapt to different load requirements. At the same time, the redundancy of the refrigeration system is increased. When one air suspension compressor fails, the other air suspension compressor can continue to operate, reducing the risk of refrigeration system shutdown, making the refrigeration system more reliable during operation, and sharing the workload of the air suspension compressor. At the same time, maintenance and repair of a single air suspension compressor will not have a significant impact on the refrigeration system, and maintenance and replacement can be carried out without interrupting the refrigeration of the system.

[0025] 2. The rubber shock-absorbing pad can reduce the vibration generated when the air suspension compressor is running, and reduce the vibration transmitted to the evaporator when the air suspension compressor is running. The first connecting soft pipe can prevent the vibration from being transmitted to the condenser through the discharge pipe, and the second connecting soft pipe can prevent the vibration from being transmitted to the evaporator through the inlet pipe when the air suspension compressor is running, so that the vibration of the chiller when the air suspension compressor is running can be reduced, the probability of the chiller connecting parts loosening due to vibration is reduced, and the noise and loosening leakage caused by vibration are reduced;

[0026] 3. The first solenoid valve and the second solenoid valve can be used to control the cooling water and the chilled water to enter the condenser and the evaporator. At the same time, the filter mesh arranged on the outer surface of the first solenoid valve and the second solenoid valve can filter the impurities in the cooling water and the chilled water. The first flow meter and the second flow meter can be used to monitor the flow of the discharged cooling water and the chilled water, thereby reducing the accumulation of impurities in the condenser and the evaporator. The flow of the condensed water and the chilled water can be monitored to conveniently know whether the filter mesh is blocked, so as to facilitate cleaning and dredging while ensuring the heat exchange efficiency of the condenser and the evaporator.

[0027] 4. When it is necessary to adjust the levelness of the water-cooled unit, it is only necessary to tighten the tensioning bolt to drive the inclined top tightening block to move inside the installation foot, so that the inclined top tightening block can push the pad to move inside the installation foot to adjust the levelness of the water-cooled unit. After the position of the pad is determined, the fixing nut can be tightened, and the tensioning bolt and the inclined top tightening block are fixed by the fixing nut, and the friction between the pad and the ground is increased by the rubber anti-skid shock-absorbing sheet, and the pad can be fixed by the limit bolt so that the pad will not fall when the water-cooled unit moves. When it is necessary to fix the water-cooled unit, it is only necessary to replace the limit bolt so that the limit bolt can pass through the pad and the rubber anti-skid shock-absorbing sheet, and after adjusting the levelness of the chiller, the limit bolt can be screwed into the bolt hole reserved on the ground, so that the chiller can be fixedly installed or non-fixedly installed.

[0042] 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 described embodiments 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.

[0043] See also Figure 1-13 The present invention provides a technical solution: an air suspension chiller with a multi-compressor structure, including an air suspension chiller with a multi-compressor structure, including a mounting base 1, the mounting base 1 is fixedly mounted on both ends of a condenser 2, and both ends of the condenser 2 are provided with partitions, the outer surface of the mounting base 1 is fixedly mounted with a connecting mounting plate 3, and the connecting mounting plate 3 is respectively penetrated and installed with an evaporator 4, and the two ends of the evaporator 4 are fixedly mounted with partitions, the outer surface of the condenser 2 is fixedly mounted with a control cabinet 23, and one end of the control cabinet 23 is fixed inside A plate-type heat dissipation pipe 35 is installed, one end of the plate-type heat dissipation pipe 35 is connected to the condenser 2, and the other end of the plate-type heat dissipation pipe 35 is connected to the evaporator 4. A frequency converter is fixedly installed at one end of the plate-type heat dissipation pipe 35 located inside the control cabinet 23, and is characterized in that two air suspension compressors 15 are fixedly installed on the outer surface of the evaporator 4, and a multi-station design is used between the evaporator 4 and the condenser 2. The multi-station design allows the working power of the chiller to be adjusted, and the chiller can still operate independently in the event of a fault, and can be conveniently repaired and maintained without shutting down.

[0044] The water cooler can be controlled and detected as a whole through the control cabinet 23, and the plate-type heat dissipation duct 35 installed inside the control cabinet 23 can prevent the inverter from generating an alarm due to high temperature under the condition of large load and high current, thereby reducing the probability of shutdown and the energy loss caused by heat. The operation of the two air-suspended compressors 15 can be controlled, and the air-suspended compressors 15 can always operate in the optimal temperature range to maintain an efficient and stable working state.

[0045] The multi-station design includes: a discharge pipe 16, which is fixedly installed at one end of the air suspension compressor 15, and an inlet pipe 17 is fixedly installed on the outer surface of one end of the air suspension compressor 15, and the discharge pipe 16 is respectively connected to the condenser 2, and the two inlet pipes 17 are respectively connected to the evaporator 4, and the diameter of the evaporator 4 is larger than the diameter of the condenser 2.

[0046] When the chilled water passes through the evaporator 4, the evaporator 4 will evaporate the refrigerant inside. The evaporated refrigerant will be extracted by the air suspension compressor 15, enter the inside of the air suspension compressor 15 from the inlet pipe 17, and be compressed by the rotation of the air suspension compressor 15, and then be discharged from the discharge pipe 16 to the inside of the condenser 2. The coordinated work of the two air suspension compressors 15 can provide a greater refrigeration capacity, and can adapt to different load requirements, and can selectively shut down one of the air suspension compressors 15. At the same time, the two air suspension compressors 15 increase the redundancy of the refrigeration system, and can automatically start and rotate the air suspension compressors 15 in sequence through the inverter control according to the overall load situation when the system is running. If one air suspension compressor 15 fails, the other air suspension compressor 15 can still continue to operate, reducing the risk of system shutdown and improving reliability. At the same time, the work load of the air suspension compressor 15 can be shared through the alternating work of the air suspension compressor 15, and the maintenance and repair of a single air suspension compressor 15 will not have a significant impact on the entire system, and can be maintained and replaced without interrupting refrigeration.

[0047] A stator 33 is fixedly installed inside the air suspension compressor 15, air bearing assemblies 32 are fixedly installed at both ends inside the air suspension compressor 15, and the air bearing assemblies 32 are located on both sides of the stator 33. A rotor assembly 31 is rotatably installed inside the air suspension compressor 15, and the rotor assembly 31 passes through the stator 33. A high-efficiency ribbed heat dissipation pipe 34 is opened inside the shell of the air suspension compressor 15, and one end of the high-efficiency ribbed heat dissipation pipe 34 is connected to the inlet pipe 17, and the other end of the high-efficiency ribbed heat dissipation pipe 34 is connected to one end of the exhaust pipe 16.

[0048] The rotor assembly 31 in the air suspension compressor 15 is supported and limited by the air bearing assembly 32. The air bearing assembly 32 allows the rotor assembly 31 to rotate stably. The arrangement of the rotor assembly 31 and the air bearing assembly 32 allows the rotor assembly 31 to rotate when the stator 33 is energized to generate a magnetic field, thereby eliminating the mechanical friction between the rotor assembly 31 and the air bearing assembly 32. This allows the air suspension compressor 15 to be suspended without the use of lubricating oil during use. When the air suspension compressor 15 is in operation, the air bearing assembly 32 allows the rotor assembly 31 to be in a non-contact, frictionless suspension state. At the same time, the high-efficiency ribbed heat dissipation device provided inside the air suspension compressor 15 The heat pipe 34 allows the refrigerant evaporated from the evaporator 4 to enter the interior of the high-efficiency ribbed heat dissipation pipe 34, taking away the heat generated when the stator 33 is running, and discharging the refrigerant after absorbing the heat into the condenser 2 for condensation, thereby ensuring that the air suspension compressor 15 always operates within the optimal temperature range and maintains an efficient and stable working state. At the same time, the frequency converter is used to accurately adjust the load of the air suspension compressor 15 within the range of 10%-100%, simplifying the overall structure of the air suspension compressor 15, improving the performance of the air suspension compressor 15 and the refrigeration effect of the entire water cooling unit, and avoiding maintenance problems caused by lubricating oil, replacement of lubricating oil and filters.

[0050] By connecting the block-shaped protrusions set on the outer surface of the mounting plate 3, the stability of the mounting plate 3 and the evaporator 4 fixed on the mounting base 1 can be improved, and the lateral bearing capacity of the mounting plate 3 can be improved, so that the mounting plate 3 and the mounting base 1 can be fixed more stably.

[0051] A flexible connection mechanism is provided between the air suspension compressor 15 and the condenser 2 and the evaporator 4, and the flexible connection mechanism includes: a rubber shock-absorbing pad 18, the rubber shock-absorbing pad 18 is fixedly installed between the evaporator 4 and the air suspension compressor 15, and a first connecting soft pipe 19 is fixedly installed at the connection between the air suspension compressor 15 and the exhaust pipe 16, and a second connecting soft pipe 20 is fixedly installed between the evaporator 4 and the inlet pipe 17.

The second connecting soft pipe 20 can reduce the vibration transmitted to the evaporator 4 through the inlet pipe 17 during the operation of the air suspension compressor 15, so that the vibration of the air suspension compressor 15 during the operation will not be transmitted to the condenser 2 and the evaporator 4, thereby reducing the loosening of parts on the water-cooled unit due to vibration, and reducing the leakage of refrigerant, cooling water and chilled water caused by the loosening of parts due to vibration.

[0053] End covers 7 are fixedly installed on one end side surface of the condenser 2 and the evaporator 4, respectively. A heat exchange pipe 5 is installed through the inside of the condenser 2 and the evaporator 4, and the heat exchange pipe 5 is divided into an upper and lower part inside the condenser 2 and the evaporator 4.

[0054] When the chilled water passes through the evaporator 4 and the cooling water passes through the condenser 2, the chilled water or the cooling water will exchange heat through the heat exchange pipe 5, allowing the heat exchange pipe 5 to rotate through the inner spiral pattern 6 to extend the passage time of the cooling water or the chilled water through the heat exchange pipe 5, so that the heat can be conducted more fully. Through the block-shaped protrusions on the outer surface of the heat exchange pipe 5, the refrigerant inside the condenser 2 and the evaporator 4 can be more fully in contact with the block-shaped protrusions on the outer surface of the heat exchange pipe 5, so that the heat exchange can be more sufficient, thereby improving the efficiency and quality of the heat exchange.

[0055] A second baffle cover 11 is fixedly installed on the outer surface of one end of the condenser 2 away from the end cover 7, a first baffle cover 8 is fixedly installed on the outer surface of one end of the evaporator 4 away from the end cover 7, and the outer surfaces of the first baffle cover 8 and the second baffle cover 11 are respectively provided with filtering mechanisms, and the filtering mechanisms include: a second baffle cover 11, a second flow meter 12 is fixedly installed on the outer surface of one end of the second baffle cover 11, a second solenoid valve 13 is fixedly installed on the end of the second baffle cover 11 away from the second flow meter 12, a first flow meter 9 is fixedly installed on the outer surface of one end of the first baffle cover 8, a first solenoid valve 10 is fixedly installed on the outer surface of one end of the first baffle cover 8 away from the first flow meter 9, and a filter mesh 14 is threadedly installed on the outer surfaces of the first solenoid valve 10 and the second solenoid valve 13.

[0056] The end cover 7, the first baffle cover 8 and the second baffle cover 11 can be conveniently installed and disassembled, and the heat exchange pipe 5 inside the condenser 2 and the evaporator 4 can be cleaned conveniently, so that the impurities generated in the cooling water and the chilled water during operation can be removed, so as to reduce the probability of scaling during the operation of the condenser 2 and the evaporator 4 and causing the refrigeration heat exchange to decrease. When the cooling water passes through the second solenoid valve 13, the impurities in the cooling water can be filtered through the filter mesh 14, and the flow rate of the cooling water passing through can be monitored by the second flow meter 12. When the chilled water passes through the first solenoid valve 10, the filter can be used to filter the impurities in the cooling water. The mesh 14 is used for filtering, and the flow rate of chilled water passing therethrough can be monitored by the first flow meter 9 to ensure that impurities in the cooling water and the chilled water can be filtered out, thereby reducing the amount of dirt condensed inside the condenser 2 and the evaporator 4. The first flow meter 9 and the second flow meter 12 can be used to determine whether the filter mesh 14 is severely clogged and whether the filter mesh 14 needs to be removed for cleaning, so that the heat exchange efficiency of the condenser 2 and the evaporator 4 will not be affected by scaling. The first flow meter 9 and the second flow meter 12 can be used to conveniently determine whether the filter mesh 14 needs to be cleaned.

An air supply pipe 22 is fixedly installed on the outer surface of the two flash evaporators 21 , and the air supply pipe 22 is connected to the inlet pipe 17 .

[0058] The flash evaporator 21 allows the high-temperature and high-pressure refrigerant after evaporation and condensation to enter the interior of the flash evaporator 21. The pressure difference of the flash evaporator 21 allows a portion of the refrigerant to evaporate, and the evaporated refrigerant gas can enter the interior of the inlet pipeline 17 through the air supply pipe 22, thereby providing refrigerant gas for the air suspension compressor 15 and reducing the energy consumption used by the air suspension compressor 15.

[0059] Mounting feet 24 are fixedly installed on the outer surfaces of both ends of the mounting base plate 1, and pads 25 are slidably installed inside the mounting feet 24. A sliding squeezing mechanism is arranged between the pads 25 and the mounting feet 24. The height and horizontality of the chiller can be conveniently adjusted through the sliding squeezing mechanism, so that unnecessary vibration and noise can be reduced when the chiller is in use, thereby ensuring the normal operation of the chiller and prolonging its service life.

[0060] By rotating the tensioning bolt 27, the inclined top tightening block 28 can be driven to move inside the mounting foot 24, so that the cushion block 25 can move up and down inside the mounting foot 24 to adjust the horizontality of the chiller, so that unnecessary noise and vibration can be reduced during the operation of the water-cooled unit, so that the chiller can operate normally and reduce problems caused by vibration, thereby extending the service life of the chiller.

[0061] The sliding extrusion mechanism includes: a tensioning bolt 27, which is threadedly connected to the mounting base plate 1 and the mounting foot 24, and an inclined top tightening block 28 is slidably installed inside the mounting foot 24, and the inclined top tightening block 28 is rotatably connected to the tensioning bolt 27, and the outer surface of the inclined top tightening block 28 is fitted with the outer surface of the cushion block 25, and a limiting bolt 29 is inserted and installed on the outer surface of the mounting foot 24, and the limiting bolt 29 is slidably connected to the cushion block 25, and the outer surface of the cushion block 25 is provided with a threaded hole, and the outer surface of the limiting bolt 29 is fitted with the outer surface of the inclined top tightening block 28, and a fixing nut 30 is threadedly installed on the outer surface of the tensioning bolt 27, and the outer surface of the fixing nut 30 is fitted with the outer surface of the mounting base plate 1, and a rubber anti-slip shock-absorbing plate 26 is fitted and fixed to the outer surface of the cushion block 25.

[0062] The rubber anti-skid shock-absorbing sheet 26 can increase the friction between the pad 25 and the ground, and reduce the vibration and noise transmitted to the ground during the operation of the chiller. After the position of the pad 25 is adjusted, the fixing nut 30 can be tightened so that the fixing nut 30 can fix the position of the inclined top tightening block 28 and the tensioning bolt 27. At the same time, the position of the inclined top tightening block 28 and the pad 25 can be limited by the limiting bolt 29, and the pad 25 can be prevented from falling when the chiller moves. At the same time, when the chiller needs to be fixed, it is only necessary to replace the limiting bolt 29 so that the limiting bolt 29 can pass through the installation foot 24, and can pass through the pad 25 and the rubber anti-skid shock-absorbing sheet 26, so that the limiting bolt 29 can be screwed into the bolt hole reserved in the ground, so that the chiller can be fixedly installed and non-fixedly installed.

[0063] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
