Description

Technical Field

[0001] This utility model relates to the field of refrigeration and air conditioning technology, and in particular to a chiller unit with air suspension evaporative cooling. Background Technology

[0002] Chillers are the core equipment of central air conditioning systems, providing cooling for large buildings. Traditional chillers mostly use screw or centrifugal compressors, along with cooling towers for heat dissipation, which suffers from drawbacks such as high operating noise, low energy efficiency, significant vibration, and complex maintenance. In particular, the mechanical bearings of the compressor require a lubrication system, posing a risk of oil contamination of the heat exchanger, and cooling towers are large, prone to scaling, and consume water. Air-suspended centrifugal compressors, as an advanced technology, utilize air bearings to achieve oil-free operation and have extremely high energy efficiency. However, their optimized integration with high-efficiency heat dissipation systems, as well as the overall vibration control and ease of maintenance of the unit, remain issues that need to be addressed. Utility Model Content

[0003] The technical problem solved by the utility model is to provide a highly practical air-suspension evaporative chiller unit that is simple to operate and has a relatively simple structure. It solves the problems mentioned in the background art of using air bearings to achieve oil-free operation with extremely high energy efficiency, but also the problems of optimizing its integration with the high-efficiency heat dissipation system, as well as the vibration control and maintenance convenience of the unit as a whole.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an air-suspension evaporative chiller unit, comprising a unit casing, a water tank fixedly installed on one side of the surface of the unit casing, a water pump installed on one side of the surface of the water tank, a compressor installed on one side inside the unit casing, a condenser installed on one side of the surface of the compressor, a filter assembly installed inside the condenser, a closing cover installed on the top of the condenser, a circulator installed on one side of the surface of the condenser, a sound-absorbing pad installed on the top of the unit casing, a sealing cover installed on the surface of the sound-absorbing pad, and buffer assemblies installed on both sides of the bottom of the unit casing.

[0005] Optionally, the filter assembly includes guide grooves formed on both sides inside the condenser, a filter plate is slidably connected inside the guide grooves, mounting grooves are formed on both sides inside the guide grooves, a telescopic rod is provided inside the mounting grooves, a spring is sleeved on the surface of the telescopic rod, and a resistance block is fixedly installed at one end of the telescopic rod.

[0006] Optionally, the diameter of the resisting block is larger than the diameter of the spring, and one end of the spring is fixedly installed on the back of the resisting block.

[0007] Optionally, the buffer assembly includes mounting blocks fixedly installed on both sides of the bottom of the unit casing, with a cross bracket rotatably connected to the bottom of the mounting block, and a guide frame provided at the bottom of the cross bracket.

[0008] Optionally, the surface of the guide frame is provided with a limiting groove, the size of which is adapted to the size of the bottom of the cross frame.

[0009] Optionally, positioning grooves are provided on both sides of the inner wall of the condenser, and the surface of the positioning grooves is connected to the output end of the compressor.

[0010] This utility model provides an air-suspension evaporative chiller unit, which has the following beneficial effects: 1. This air-suspension evaporative chiller unit utilizes a filter assembly installed inside the condenser. Springs and telescopic rods provide elasticity, ensuring the filter plates are always pressed firmly into the guide groove by the resistance block. This provides excellent sealing and easy disassembly and assembly. The filter plates can be directly removed for cleaning or replacement by simply opening the closing cover, effectively preventing impurities from clogging the condenser pipes and guaranteeing heat exchange efficiency and unit stability.

[0011] 2. This air-suspension evaporative chiller unit effectively absorbs and isolates the minute vibrations generated during compressor operation through the expansion and contraction of the cross-frame structure and the buffer components at the bottom of the unit, preventing the vibrations from being transmitted to the foundation and improving the stability of the equipment operation. The sound-absorbing pad at the top further reduces the aerodynamic noise generated by components such as the fan, achieving low-noise operation. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0015] Please see Figs. 1 to 4 This utility model provides a technical solution: an air-suspension evaporative chiller unit, including a unit shell 1, a water tank 2 fixedly installed on one side of the surface of the unit shell 1, a water pump 3 installed on one side of the surface of the water tank 2, a compressor 4 installed on one side inside the unit shell 1, a condenser 5 installed on one side of the surface of the compressor 4, positioning grooves are provided on both sides of the inner wall of the condenser 5, the surface of the positioning grooves is connected to the output end of the compressor 4, a filter assembly 6 is provided inside the condenser 5, a closing cover 7 is provided on the top of the condenser 5, a circulator 8 is provided on one side of the surface of the condenser 5, a sound-absorbing pad 9 is provided on the top of the unit shell 1, a sealing cover 10 is provided on the surface of the sound-absorbing pad 9, and buffer assemblies 11 are provided on both sides of the bottom of the unit shell 1.

[0016] The filter assembly 6 includes guide grooves on both sides inside the condenser 5. A filter plate 61 is slidably connected inside the guide grooves. Mounting grooves are provided on both sides inside the guide grooves. A telescopic rod 62 is provided inside the mounting grooves. A spring 63 is sleeved on the surface of the telescopic rod 62. A resisting block 64 is fixedly installed at one end of the telescopic rod 62. The diameter of the resisting block 64 is larger than the diameter of the spring 63. One end of the spring 63 is fixedly installed on the back of the resisting block 64.

[0017] When filtering the water entering the condenser 5, the personnel press the filter plate 61 downward through the guide groove. After the surface of the filter plate 61 comes into contact with the surface of the resisting block 64, the filter plate 61 will press the spring 63 on the telescopic rod 62 through the resisting block 64. When the filter plate 61 moves below the resisting block 64, the spring 63 on the telescopic rod 62 will drive the resisting block 64 to move synchronously to the center. The resisting block 64 positions the filter plate 61, and the filter plate 61 filters the water entering the condenser 5. The filter plate 61 is easy for personnel to quickly disassemble and install.

[0018] The buffer assembly 11 includes mounting blocks 111 fixedly installed on both sides of the bottom of the unit housing 1. A cross frame 112 is rotatably connected to the bottom of the mounting block 111. A guide frame 113 is provided at the bottom of the cross frame 112. A limiting groove is provided on the surface of the guide frame 113. The size of the limiting groove is adapted to the size of the bottom of the cross frame 112.

[0019] The upper end of the cross frame 112 of the buffer assembly 11 is hinged to the unit shell 1 via the mounting block 111, and the lower end slides within the limiting groove of the guide frame 113. When the unit vibrates, the cross frame 112 undergoes expansion and contraction deformation, thereby consuming vibration energy and playing a buffering role.

[0020] In this invention, the working steps of the device are as follows: First, the air-suspension compressor 4 compresses the refrigerant and sends it to the condenser 5 for heat dissipation. The circulator 8 starts, and a fan drives airflow through the heat exchange tube bundle of the condenser 5. Simultaneously, a spray system sprays water onto the tube bundle, and some of the water evaporates, carrying away a large amount of heat, achieving efficient cooling of the refrigerant. The cooled refrigerant, after being throttled, enters another heat exchanger to evaporate, absorbing heat from the chilled water, thereby producing chilled water for users. During this process, the filter assembly 6 ensures the cleanliness of the air entering the heat exchanger. When filtering the water entering the condenser 5, the personnel press the filter plate 61 downward through the guide groove. After the surface of the filter plate 61 contacts the surface of the resisting block 64, the filter plate 61 will press the spring 63 on the telescopic rod 62 through the resisting block 64. When the filter plate 61 moves below the resisting block 64, the spring 63 on the telescopic rod 62 will drive the resisting block 64 to move synchronously in the middle. The resisting block 64 positions the filter plate 61, and the filter plate 61 filters the water entering the condenser 5. The filter plate 61 is easy for personnel to quickly disassemble and install. The upper end of the cross frame 112 is hinged to the unit shell 1 through the mounting block 111, and the lower end slides in the limiting groove of the guide frame 113. When the unit vibrates, the cross frame 112 undergoes telescopic deformation, thereby consuming vibration energy.
