Description

Technical Field

[0001] This application relates to the technical field of air conditioners, and particularly refers to a detachable and assembled air conditioner unit. Background Art

[0002] As a key device for regulating modern buildings and industrial environments, large-scale chilled water central air-conditioning host units play an important role. They mainly achieve the regulation of indoor temperature, humidity, and air quality by the coordinated operation of core components such as compressors, evaporators, condensers, and expansion valves, providing users with a comfortable indoor environment.

[0003] Currently, in traditional air-cooled chilled water units, most of the main components such as compressors, evaporators, condensers, and expansion valves are directly fixed on the bottom sheet metal of the unit. This design makes it impossible to produce each component separately in a modular manner and also unable to achieve overall disassembly. Moreover, such air conditioner units generally adopt an integrated design, that is, all components are integrated in a single housing.

[0004] However, there are many problems in the actual application of existing large-scale chilled water central air-conditioning host units:

[0005] First, the integrated design makes the unit occupy a large space. In large buildings or industrial sites, restricted by the site space, the installation is difficult and the flexibility is poor.

[0006] Second, due to the inability to perform modular disassembly according to the actual needs of the customer site, it is difficult to adapt to complex installation environments during installation. And during later maintenance, the entire unit needs to be operated, increasing the maintenance difficulty and cost.

[0007] Third, the existing units cannot achieve modular production, resulting in difficulty in parallel processing of each part during the production process. This not only increases the production cost but also prolongs the production cycle, making it difficult to meet the market's demands for efficient production and personalized customization. Summary of the Invention

[0008] In view of the above problems in the prior art, this application provides a detachable and assembled air conditioner unit. This application has made an innovative improvement to the structural design of the air conditioner unit, disassembling it into three independent units: a thermal management module, a base module, and a condensation module, and adopting a split modular design to achieve the function of rapid disassembly and assembly between modules.

[0009] To achieve the above object, the first aspect of this application provides a detachable and assembled air conditioner unit, including: a thermal management module, a base module, and a condensation module:

[0010] The thermal management module is fixed on the base module through a bracket, and the condensation module is connected to the thermal management module through an air pipe and a liquid pipe;

[0011] The thermal management module includes an evaporator, a compressor, and an economizer; wherein, the evaporator is provided on the bracket, the compressor is respectively provided on the evaporator through a fixed seat, and the economizer is provided on the evaporator through a base; the compressor is communicated with the evaporator, and the compressor is communicated with the economizer;

[0012] The condensation module includes: a condenser, a condensation fan, and a support frame; wherein, the condensers are arranged in an array on the support frame, each row includes a plurality of the condensers, the condensation fans are arranged in an array above the condensers, and each row includes a plurality of condensation fans; the condensers are connected to the thermal management module through the gas pipe and the liquid pipe.

[0013] Thus, the present application has made an innovative improvement to the structural design of the air conditioner unit, disassembling it into three independent units: a thermal management module, a base module, and a condensation module, adopting a split modular design, and realizing the functions of rapid disassembly and assembly between modules.

[0014] One of the core advantages of the present application lies in the parallel production mode: the independent structures of the three modules completely break the limitations of the traditional integrated production mode, enabling the thermal management module, the base module, and the condensation module to be produced synchronously in parallel without relying on each other's manufacturing progress. This production method can significantly shorten the overall delivery cycle, not only reducing the dependency relationships between components, but also enabling multiple modules to be produced simultaneously, reducing project risks caused by delays in the production of a single module, providing a strong guarantee for the efficient and stable progress of the data center construction project, and laying a solid foundation for the smooth implementation and on-time delivery of the data center construction.

[0015] Another core advantage of the present application lies in the flexible deployment ability: users can freely combine or adjust the module layout according to the constraint conditions of the actual installation scenario (such as high-rise buildings, narrow spaces, etc.). The modular design significantly reduces the dependence of the equipment on the installation space and significantly improves the equipment deployment efficiency, especially suitable for the rapid installation requirements under complex working conditions.

[0016] As a possible implementation manner of the first aspect, the thermal management module further includes an electronic expansion valve and a dryer filter;

[0017] The dryer filter is arranged between the condenser and the economizer; and is used to remove impurities in the refrigerant;

[0018] The electronic expansion valve is arranged between the compressor and the economizer; and is used to control the refrigerant flow rate flowing into the economizer.

[0019] In this way, by removing moisture and impurities from the refrigerant, the drying filter can prevent these harmful substances from entering the key components of the system (such as compressors, economizers, etc.), thereby reducing the risk of corrosion and blockage and ensuring the long-term stable operation of the air-conditioning unit. The electronic expansion valve can precisely control the refrigerant flow rate into the economizer, enabling the air-conditioning unit to maintain the best heat exchange efficiency under different operating conditions. This not only improves the energy efficiency ratio of the entire refrigeration cycle but also helps achieve more precise temperature control.

[0020] As a possible implementation of the first aspect, a two-way three-way stop valve is provided on the evaporator. The two-way three-way stop valve is used for the overhaul and maintenance of the safety valve, so as to avoid the shutdown of the air-conditioning unit or refrigerant leakage when the safety valve is damaged or under overhaul.

[0021] Two safety valves are installed on the two-way three-way stop valve. The safety valves are used to automatically open and release excessive pressure when the pressure exceeds the set value.

[0022] Among them, the safety valve is equipped with a leakage port, which is designed downward. The leakage ports of the two safety valves are connected in parallel through pipelines.

[0023] In this way, configuring two safety valves forms a dual protection mechanism. Even if one of them fails, the other can still continue to function, improving the reliability of the air-conditioning unit.

[0024] As a possible implementation of the first aspect, both the condensation module and the thermal management module adopt a symmetric design.

[0025] The condenser, the condensation fan, the evaporator, and the compressor are all arranged symmetrically left and right along the center line of the air-conditioning unit, forming a balanced distribution structure.

[0026] In this way, through the symmetric design, the air-conditioning unit achieves a balanced distribution of the forces on the equipment installation platform, thereby significantly reducing the risk of damage to the customer's roof structure. Specifically, the symmetric layout ensures the uniform distribution of the weight and operating load of the air-conditioning unit, avoiding mechanical vibration or tilt caused by the center of gravity shift and protecting the safety and integrity of the building structure.

[0027] As a possible implementation of the first aspect, the base module includes a rectangular frame.

[0028] Several end beams and several wide beams are provided inside the rectangular frame. Among them, the brackets are arranged on the wide beams.

[0029] The end beams are used to connect the short sides of the rectangular frame to enhance the structural strength of the rectangular frame.

[0030] The wide beam is used to connect the short sides of the rectangular frame to bear the weight of the thermal management module.

[0031] In this way, the design of the end beam enhances the structural rigidity of the entire frame, effectively preventing deformation or damage caused by external forces such as wind pressure and earthquake. The wide beam is specially designed to bear the weight of the thermal management module, ensuring that the base can provide sufficient support even under long-term high-load working conditions, extending the service life of the equipment.

[0032] As a possible implementation of the first aspect, the base module further includes lifting lugs;

[0033] The lifting lugs are fixedly connected to the rectangular frame;

[0034] The lifting lugs are used for hoisting the whole machine.

[0035] In this way, by using the lifting lugs for hoisting, the rapid handling and positioning of the air-conditioning unit can be achieved, especially suitable for the installation site of large or heavy equipment, saving a large amount of labor and time costs.

[0036] As a possible implementation of the first aspect, the air-conditioning unit further includes an electric control cabinet;

[0037] The electric control cabinet is fixed on the rectangular frame through a mounting rack.

[0038] In this way, the electric control cabinet is the "brain" of the air-conditioning unit, which is not only responsible for power distribution, but also performs complex control, monitoring and protection functions, improving the performance and reliability of the air-conditioning unit from multiple dimensions.

[0039] As a possible implementation of the first aspect, when the condensing module and the base module are assembled from top to bottom, an integrated air-conditioning unit is formed.

[0040] In this way, the integrated structure enables the weight of the condensing module to be evenly transmitted to the ground through the base module, reducing the vibration transmission path during the operation of the unit and reducing the risk of noise and equipment wear.

[0041] As a possible implementation of the first aspect, when the air-conditioning unit is an integrated air-conditioning unit, the condensing module and the base module have the same outer contour and size, and the connection surfaces are aligned.

[0042] In this way, the same outer contour and size enable seamless docking of the two modules during assembly, the connection surfaces are completely fitted, reducing gaps and misalignments caused by dimensional differences, and enhancing the stability of the overall structure. Moreover, the unified outer contour and size make the overall shape of the integrated air-conditioning unit more regular and concise, and can better integrate into the building environment in the installation space, reducing the sense of visual fragmentation of the space.

[0043] As a possible implementation of the first aspect, when the condensation module and the base module are placed adjacent to each other and assembled, a split air conditioner unit is formed.

[0044] In this way, the split design provides users with another installation method, allowing the positions of each module to be flexibly arranged according to the on-site conditions. For example, in places with limited space or complex layouts, such as high-rise buildings, narrow alleys, etc., the condensation module and the base module can be placed in the most suitable positions respectively to optimize space utilization.

[0051] The following are embodiments in conjunction with the drawings to further illustrate the technical solutions provided by the present application. It should be understood that the system structures and service scenarios provided in the embodiments of the present application are mainly to illustrate possible implementation manners of the technical solutions of the present application and should not be construed as the only limitation of the technical solutions of the present application. Those of ordinary skill in the art know that with the evolution of the system structure and the emergence of new service scenarios, the technical solutions provided by the present application are equally applicable to similar technical problems.

[0052] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. In case of any inconsistency, the meaning stated in this specification or the meaning derived from the content recorded in this specification shall prevail. Additionally, the terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0053] An embodiment of this application provides a disassemblable and assembled air conditioning unit, as Figure 1 shown, including: a thermal management module, a base module, and a condensation module:

[0054] The thermal management module is fixed on the base module through bracket 1, and the condensation module is connected to the thermal management module through gas pipe 2 and liquid pipe 3;

[0055] The thermal management module includes an evaporator 4, a compressor 5, and an economizer 6; among them, the evaporator 4 is arranged on the bracket 1, the compressor 5 is respectively arranged on the evaporator 4 through a fixing seat 7, and the economizer 6 is arranged on the evaporator 4 through a base 8; the compressor 5 is communicated with the evaporator 4, and the compressor 5 is communicated with the economizer 6;

[0056] The condensation module includes: a condenser 9, a condensation fan 10, and a support frame 11; among them, the condenser 9 is arranged on the support frame 11 in an array, each row contains several condensers 9, the condensation fan 10 is arranged above the condenser 9 in an array, and each row contains several condensation fans 10; the condenser 9 is connected to the thermal management module through the gas pipe 2 and the liquid pipe 3.

[0057] Among them, the condenser 9 can adopt a high-efficiency heat exchanger, the condensation fan 10 can adopt a low-noise fan, the support frame 11 can adopt carbon steel sheet metal or stainless steel sheet metal, the compressor 5 can adopt a high-efficiency and energy-saving screw compressor 5, and the evaporator 4 can adopt a high-efficiency heat exchanger.

[0058] Combined with Figure 1 shown, the structure from top to bottom is successively the condensation module, the thermal management module, and the base module.

[0059] It should be noted that, as shown in Figure 1 shown, two compressors 5 are designed. Of course, in actual applications, according to different requirements, the number of compressors can be increased to three or more. This flexible design allows the air conditioning unit to adjust the number of operating compressors according to the change of load, ensuring optimal performance under different working conditions.

[0060] In addition, the condenser 9 is connected to the thermal management module through the gas pipe 2 and the liquid pipe 3. More specifically, the gas pipe 2 is connected to the exhaust pipe of the compressor, and the liquid pipe 3 is connected to the dryer filter.

[0061] In this way, the present application has made an innovative improvement to the structural design of the air-conditioning unit. It disassembles the air-conditioning unit into three independent units: the thermal management module, the base module, and the condensation module, and adopts a split modular design to achieve the functions of rapid disassembly and assembly between modules.

[0062] One of the core advantages of the present application lies in the parallel production mode: the independent structures of the three modules completely break the limitations of the traditional integrated production mode, enabling the thermal management module, the base module, and the condensation module to be produced synchronously and in parallel without relying on each other's manufacturing progress. This production method can significantly shorten the overall delivery cycle, not only reducing the dependencies between components, but also allowing multiple modules to be produced simultaneously, reducing project risks caused by delays in the production of a single module, providing a strong guarantee for the efficient and stable progress of the data center construction project, and laying a solid foundation for the smooth implementation and on-time delivery of the data center construction.

[0063] Another core advantage of the present application lies in its flexible deployment ability: users can freely combine or adjust the module layout according to the constraints of the actual installation scenario (such as high-rise buildings, narrow spaces, etc.). The modular design significantly reduces the dependence of the equipment on the installation space and significantly improves the equipment deployment efficiency, especially suitable for the rapid installation requirements under complex working conditions.

[0064] In some embodiments, the bracket 1 can be directly welded to the evaporator 4, and specific reference can be made to Figure 4 as shown.

[0065] In some embodiments, both the condensation module and the thermal management module adopt a symmetric design;

[0066] The condenser 9, the condensation fan 10, the evaporator 4, and the compressor 5 are all arranged symmetrically left and right along the center line of the air-conditioning unit to form a balanced distribution structure.

[0067] In this way, through the symmetric design, the air-conditioning unit realizes the balanced distribution of the force on the equipment installation platform, thereby significantly reducing the risk of damage to the customer's roof structure. Specifically, the symmetric layout ensures the uniform distribution of the weight and operating load of the air-conditioning unit, avoiding mechanical vibration or tilt caused by the center of gravity shift, and protecting the safety and integrity of the building structure.

[0068] In some embodiments, the base module includes a rectangular frame 13;

[0069] Inside the rectangular frame 13, there are several end beams 14 and several wide beams 15; among them, the bracket 1 is arranged on the wide beam 15;

[0070] The end beam 14 is used to connect the short sides of the rectangular frame 13 to enhance the structural strength of the rectangular frame 13;

[0071] The wide beam 15 is used to connect the short sides of the rectangular frame 13 to bear the weight of the thermal management module.

[0072] In practical applications, the number of end beams 14 and wide beams 15 can be flexibly set according to different load requirements and installation environments. For example, in cases where higher load-bearing capacity is required or when facing greater wind pressure, increasing the number of wide beams 15 can more effectively disperse the weight load and enhance structural stability.

[0073] In this way, the design of the end beam 14 enhances the structural rigidity of the entire frame and effectively prevents deformation or damage caused by external forces such as wind pressure and earthquakes. The wide beam 15 is specially designed to bear the weight of the thermal management module, ensuring that even under long-term high-load working conditions, the base can provide sufficient support force and extend the service life of the equipment.

[0074] In some embodiments, the base module further includes a lifting lug 16;

[0075] The lifting lug 16 is fixedly connected to the rectangular frame 13;

[0076] The lifting lug 16 is used for hoisting the whole machine.

[0077] Specifically, the fixed connection between the lifting lug 16 and the rectangular frame 13 can include welding or connection by fasteners.

[0078] The welding connection method has the significant advantages of high connection strength and good integrity, and is particularly suitable for scenarios with extremely high requirements for structural rigidity and load-bearing capacity. For example, when the structure needs to bear large impact loads or dynamic loads, the welding connection can ensure a tight combination between the lifting lug 16 and the rectangular frame 13, and there will be no relative displacement due to external forces, thus ensuring the stability and reliability of the entire structure.

[0079] Connecting by fasteners, on the other hand, has the advantages of convenient installation and disassembly, easy maintenance and replacement. In cases where it is necessary to frequently check, repair or replace the lifting lug 16 or the rectangular frame 13, the fastener connection is a more suitable choice. For example, in some industrial production environments with high requirements for equipment maintainability, using fastener connection can greatly shorten the equipment downtime for maintenance and improve production efficiency. At the same time, the fastener connection can also control the tightness of the connection by adjusting the tightening torque to adapt to different working conditions.

[0080] Therefore, according to different actual requirements, a suitable connection method can be selected, which is not specifically limited herein to meet the requirements of different scenarios.

[0081] In this way, by using the lifting lug 16 for hoisting, the rapid handling and positioning of the air-conditioning unit can be achieved, which is especially suitable for the installation site of large or heavy equipment, saving a large amount of labor and time costs.

[0082] In some embodiments, the air-conditioning unit further includes an electric control cabinet 17;

[0083] The electric control cabinet 17 is fixed on the rectangular frame 13 through a mounting rack.

[0084] Among them, the condensing fan 10 can be connected to the electric control cabinet 17 through a cable, realizing the centralized control and monitoring of the condensing fan 10.

[0085] In addition, the electric control cabinet 17 provides a stable power supply to ensure that each component in the air-conditioning unit can operate normally.

[0086] The electric control cabinet is also responsible for controlling the start and stop of each device in the air-conditioning unit, such as the compressor 5, the condensing fan 10, the evaporator 4 fan, etc.

[0087] In this way, the electric control cabinet 17 is the "brain" of the air-conditioning unit, which not only is responsible for power distribution, but also performs complex control, monitoring and protection functions, improving the performance and reliability of the air-conditioning unit from multiple dimensions.

[0088] In some embodiments, as Figure 2 shown, when the condensing module and the base module are assembled from top to bottom, an integrated air-conditioning unit is formed.

[0089] Specifically, when the condensing module and the base module are installed, high-strength bolts and nuts are used for fixation.

[0090] In this way, the integrated structure enables the weight of the condensing module to be evenly transmitted to the ground through the base module, reducing the vibration transmission path during the operation of the unit and reducing the risk of noise and equipment wear.

[0091] In some embodiments, when the air-conditioning unit is an integrated air-conditioning unit, the condensing module and the base module have the same outer contour and size, and the connection surfaces are aligned.

[0092] Thus, the same outer contour and size enable seamless docking when the two modules are assembled, with the connecting surfaces fitting perfectly, reducing gaps and misalignments caused by size differences and enhancing the stability of the overall structure. Moreover, the unified outer contour and size make the overall shape of the integrated air conditioner unit more regular and concise, enabling it to better blend into the building environment within the installation space and reducing the visual fragmentation of the space.

[0093] In some embodiments, as Figure 3 shown, when the condensation module and the base module are placed adjacent to each other and assembled, a split air conditioner unit is formed.

[0094] Thus, the split design provides users with another installation method, allowing for flexible arrangement of the positions of each module according to on-site conditions. For example, in places with limited space or complex layouts, such as high-rise buildings (where there are load-bearing requirements on the building roof, i.e., the load per square meter cannot exceed the design requirements of the building), narrow alleys, etc., the condensation module and the base module can be placed in the most suitable positions respectively to optimize space utilization.

[0095] In some embodiments, as Figure 4 shown, a two-way three-way stop valve 12 is provided on the evaporator 4, and the two-way three-way stop valve 12 is used to control the flow direction of the refrigerant in the evaporator 4;

[0096] Two safety valves are installed on the two-way three-way stop valve 12, and the safety valves are used to automatically open when the pressure exceeds the set value to release the excessive pressure;

[0097] Among them, the safety valve is equipped with a leakage port, the leakage port is designed downward, and the leakage ports of the two safety valves are connected in parallel through pipelines.

[0098] Thus, configuring two safety valves forms a double protection mechanism. Even if one of them fails, the other can still function, improving the reliability of the air conditioner unit.

[0099] In some embodiments, as Figure 4 shown, a butterfly valve is provided at the suction port of each compressor 5. This butterfly valve is mainly used to cut off the suction passage when the compressor 5 is being repaired, isolating the compressor 5 from other parts, facilitating maintenance personnel to safely and conveniently perform operations such as inspection, maintenance, and replacement on the compressor 5. A ball valve and a check valve assembly are equipped at the exhaust port of each compressor 5. Among them, the ball valve can cut off the exhaust passage during maintenance to isolate the compressor 5 from the air conditioner unit; the check valve assembly is used to prevent refrigerant backflow during normal operation to ensure the normal flow direction of the refrigeration cycle.

[0100] In some embodiments, as Figure 4 and Figure 5 shown, Figure 4 andFigure 5 They are all thermal management modules, just from different perspectives. The thermal management module further includes an electronic expansion valve 18 and a dryer filter 22;

[0101] The dryer filter 22 is arranged between the condenser 9 and the economizer 6; it is used to remove impurities in the refrigerant;

[0102] The electronic expansion valve 18 is arranged between the compressor 5 and the economizer 6; it is used to control the refrigerant flow rate into the economizer.

[0103] In this way, by removing moisture and impurities in the refrigerant, the dryer filter can prevent these harmful substances from entering the key components of the system (such as the compressor, economizer, etc.), thereby reducing the risk of corrosion and blockage and ensuring the long-term stable operation of the air-conditioning unit. The electronic expansion valve can make the air-conditioning unit maintain the best heat exchange efficiency under different working conditions by precisely controlling the refrigerant flow rate into the economizer. This not only improves the energy efficiency ratio of the entire refrigeration cycle but also helps to achieve more precise temperature control.

[0104] In some embodiments, as Figure 4 shown, the evaporator 4 is also provided with an inlet / outlet 19 and a water outlet 20. The inlet / outlet 19 and the water outlet 20 refer to the inlet / outlet of the chilled water supplied to the customer.

[0105] It should be noted that existing air-conditioning units generally have the problem of low energy utilization efficiency, mainly because the refrigeration capacity generated per unit area is relatively low. Through optimized design, this application can accommodate more and larger compressors 5, evaporators 4, and condensers 9 under the same floor area (i.e., the same length and width dimensions of the unit), thereby achieving a higher refrigeration capacity output. That is to say, compared with the water chillers of other manufacturers in the same industry, the air-conditioning unit of this application can provide more efficient refrigeration performance under the same space conditions.

[0106] Next, in combination with the above structural description, the working principle of the air-conditioning unit described in this application will be described:

[0107] The refrigerant in the low-temperature and low-pressure gaseous state first enters the two parallel magnetic levitation compressors 5 in the thermal management module. The compressor 5 compresses the refrigerant, causing its pressure and temperature to rise sharply, and it becomes a high-temperature and high-pressure gaseous refrigerant. In this process, the compressor 5 provides power for the entire refrigeration cycle and drives the refrigerant to circulate in the system.

[0108] The gaseous refrigerant at high temperature and high pressure enters the economizer 6 through the compressor 5. The economizer 6 further regulates the refrigerant through its internal structure, such as performing partial gas-liquid separation or subcooling treatment, etc., to improve the overall performance and efficiency of the refrigeration system. The refrigerant regulated by the economizer 6 enters the condenser 9 in the condensation module. In the condenser 9, with the forced convection of the condenser fan 10 array, a large amount of air flows through the condenser 9, taking away the heat of the refrigerant. The refrigerant releases heat in this process and gradually condenses from the gaseous state into a liquid state at medium temperature and high pressure.

[0109] After the liquid refrigerant at medium temperature and high pressure flows out of the condenser 9, it enters the electronic expansion valve 18 through the liquid pipe 3. The electronic expansion valve 18 precisely regulates the flow rate of the refrigerant according to the operating conditions and set parameters of the air conditioner unit, and throttles and reduces the pressure of the refrigerant, making it into a gas-liquid two-phase mixture state at low temperature and low pressure.

[0110] The gas-liquid two-phase mixture refrigerant at low temperature and low pressure enters the evaporator 4 in the thermal management module. In the evaporator 4, the refrigerant absorbs the heat of the chilled water in the evaporator 4 and vaporizes, changing from the gas-liquid two-phase mixture state to the gaseous state at low temperature and low pressure. At the same time, the chilled water in the evaporator 4 decreases in temperature due to the absorption of heat, thus achieving the refrigeration effect. The evaporated gaseous refrigerant at low temperature and low pressure is sucked into the compressor 5 again to start the next refrigeration cycle.
