Abstract

This invention discloses a large-space wind island structure for railway station waiting halls, relating to the field of air conditioning outlet structure technology. It includes an island-type air conditioning unit and an extended air curtain component, umbrella-shaped and positioned on the upper part of the island-type air conditioning unit, with one end connected to the air outlet of the unit, used to guide airflow in all directions. The extended air curtain component includes horizontal and lateral extensions. This invention achieves controlled airflow within the interlayer through refined flow channel design. Utilizing the gradually expanding structure and pressure gradient guidance in the airflow guiding and noise reduction components, eddy current losses and disordered turbulence during airflow transport are reduced. Airflow is efficiently transported to the required areas, reducing ineffective energy consumption. Compared to the traditional approach of forcibly extending the air delivery distance by increasing fan power, this solution effectively reduces fan energy consumption while achieving the same or even better coverage effect, and also reduces the cost of additional noise reduction treatment due to excessive noise.

Description

Technical Field

[0001] This invention belongs to the field of air conditioning outlet structure technology, specifically, it relates to a large-space wind island structure for railway station waiting halls. Background Technology

[0002] In the construction of modern railway transportation hubs, high-speed railway station waiting halls generally adopt large-span, high-ceiling, and transparent architectural designs to meet the needs of passenger flow and spatial aesthetics. Such large-space environments place higher demands on thermal comfort control. Island air conditioners (also known as air islands or air conditioning columns), as independent air supply devices separate from the walls, have become an important component of station air conditioning systems because they can directly and precisely supply air to the waiting area while also serving as space partitions and decorative elements.

[0003] Existing island-style air conditioners mostly adopt a vertical cabinet structure, with air outlets concentrated on the upper side or top of the cabinet. However, as passengers' expectations for the quality of the waiting environment continue to rise, this structure has revealed significant shortcomings in actual operation. First, the air delivery distance and coverage are severely limited. The traditional air outlet layout causes the airflow to attenuate too quickly, failing to effectively reach distant areas. This results in uneven temperature distribution in the waiting hall, with areas near the equipment prone to being too cold or too hot, while distant areas lack effective airflow coverage. This forces operators to compensate by increasing the number of units or increasing fan power, leading to excessive energy consumption. Second, the airflow quality fails to meet human comfort requirements. To extend the air delivery distance, the equipment often relies on high-speed airflow, causing passengers near the equipment to be directly subjected to strong winds, resulting in significant discomfort. At the same time, the existing structure lacks refined airflow separation and softening, failing to transform high-speed airflow into a uniform and gentle breeze, making it difficult to balance air delivery distance and human comfort. Furthermore, aerodynamic noise is a prominent issue. Island-type air conditioners are mostly installed in the quiet central area of ​​the waiting hall. The traditional straight-through flow channel design causes strong turbulence when the high-speed airflow passes through the air outlet, resulting in high-frequency wind shear noise. The mechanical noise of the fan is also directly leaked out through the simple air outlet, creating continuous interference in the quiet environment of the high-speed rail station and significantly reducing the waiting experience for passengers.

[0004] For example, Chinese invention patent application publication number CN224215545U discloses a central air conditioning outlet noise reduction device, which includes an air receiving duct, a bucket-shaped air expander, an air outlet hood, a noise reduction frame, an air direction guide frame, and a protective frame; the lower end of the air receiving duct is provided with a bucket-shaped air expander, the lower end of the bucket-shaped air expander is provided with an air outlet hood, and the end of the air outlet hood away from the bucket-shaped air expander is provided with an embedded groove, and the inside of the embedded groove is provided with a noise reduction frame, an air direction guide frame, and a protective frame in sequence;

[0005] And Chinese invention patent application publication number CN221098865U, which discloses a dual-range island air conditioning unit with ground return air, including a vertical air conditioning shell, an air conditioning unit and a control cabinet;

[0006] Of the two existing technologies mentioned above, the technical solution of Publication No. CN224215545U improves the noise problem by using a bucket-shaped air diffuser and a sound-absorbing frame, but it only focuses on local noise reduction and fails to solve the problem of insufficient air supply coverage. The technical solution of Publication No. CN221098865U expands the air supply range by using a combination of slotted air outlets and long-range jet nozzles, but it ignores airflow softening and noise control and cannot avoid the problem of strong wind blowing directly. These technologies are limited to improving a single problem and fail to build a comprehensive solution that takes into account air supply distance, airflow quality and noise suppression. As a result, the thermal comfort and acoustic environment quality of the large-space waiting environment cannot be optimized in a coordinated manner for a long time. Therefore, a large-space wind island structure for railway station waiting halls is proposed. Summary of the Invention

[0007] The purpose of this invention is to provide a large-space wind island structure for railway station waiting halls to solve the problems mentioned in the background art.

[0008] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: a large-space wind island structure for railway station waiting halls, including an island air conditioning unit, and further including: an extended air curtain component, which is arranged in an umbrella shape on the upper part of the island air conditioning unit, and one end is connected to the air outlet of the island air conditioning unit, for guiding the air to extend in all directions; the extended air curtain component includes a horizontal extension component and a lateral extension component, both of which are provided with a sandwich layer, and the horizontal extension component and the lateral extension component are connected; a flow guiding and noise reduction component is arranged in the sandwich layer of the horizontal extension component, for separating, guiding and dissipating airflow; the lateral extension component is provided with multiple arc-shaped plates, and flow guiding and noise reduction channels are formed between the multiple arc-shaped plates.

[0009] Preferably, the horizontal extension includes a base plate and a top cover plate, and the lateral extension includes a base plate and a top cover plate. The interlayer is located between the base plate and the top cover plate and between the base plate and the top cover plate. It also includes a mounting arm installed on the island air conditioner body, and the horizontal extension and the lateral extension are connected to the mounting arm.

[0010] Preferably, the airflow guiding and noise reduction assembly includes multiple sets of spindle-shaped airflow guiding and rectifying components installed in the interlayer of the horizontal extension member. Each set of spindle-shaped airflow guiding and rectifying components is staggered. Each spindle-shaped airflow guiding and rectifying component includes symmetrical streamlined air panels, open parts located at both ends of the streamlined air panels, and cylinders located between the streamlined air panels.

[0011] Preferably, the streamlined air vane includes a horizontal plate and an inner curved plate integrally formed with both ends of the horizontal plate; the open part includes a symmetrically arranged curved plate; a cross-shaped dispersion channel is formed between the open part and the inner curved plate on one end of the symmetrical streamlined air vane; a central guide channel is formed between the streamlined air vane, the open part, and the cylinder; a soft air channel is formed between each group of two adjacent spindle-shaped guide and rectifier parts; and an S-shaped air duct is formed between the open parts on two groups of adjacent spindle-shaped guide and rectifier parts.

[0012] Preferably, the base plate is provided with a plurality of air outlet slots, which are located between the S-shaped air ducts and between the streamlined air plates spanning each group of spindle-shaped air guides and rectifiers.

[0013] Preferably, the airflow guiding and noise reduction assembly includes multiple sets of conical airflow guides installed in the interlayer of the horizontal extension member, with each set of conical airflow guides being staggered. Each conical airflow guide includes a clamp-type airflow guide and a symmetrical hook airflow guide. The clamp-type airflow guide has an air outlet hole one, and the symmetrical hook airflow guide has an air outlet hole two.

[0014] Preferably, the clamp-type flow guide and disperser includes a V-shaped plate and a bend at one end of the V-shaped plate; the symmetrical hook flow guide and disperser includes symmetrically arranged hook curved surface parts, the hook curved surface parts having the same bending direction as the bend; wherein, a first converging dispersion channel is formed between the hook curved surface parts and the bend, and a second converging dispersion channel is formed between the symmetrical hook flow guide and disperser and the first converging dispersion channel.

[0015] Preferably, the airflow guiding and noise reduction assembly includes multiple sets of double-layer airflow guiding and dispersing components installed in the interlayer of the horizontal extension component. Each set of double-layer airflow guiding and dispersing components is staggered. The double-layer airflow guiding and dispersing components include small C-shaped bodies and large C-shaped bodies. An air outlet groove is provided on the base plate between each set of double-layer airflow guiding and dispersing components.

[0016] Preferably, the small C-shaped body includes a plate and curved panels two located at both ends of the plate; the large C-shaped body includes a plate and side plates located at both ends of the plate, the plate has an opening groove, and the side plate has a bend two at the end away from the plate, the bend two bending direction facing the curved panel two; a flow channel is formed between the side plate, the bend two and the curved panel two.

[0017] Preferably, the mounting arm has multiple interconnecting ports that are connected to the airflow and noise reduction channel, the base plate has multiple air outlets that are connected to the airflow and noise reduction channel, and the arc-shaped plate has multiple through-holes.

[0018] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0019] 1. The large-space air island structure in the waiting hall of this railway station utilizes umbrella-shaped extended air curtain components at the top of the island air conditioner, changing the traditional direct-blowing air supply mode. Airflow first enters the interlayer of the horizontal extension component, where internal airflow guiding and noise reduction components direct the airflow to the far end, before it is delivered through air outlet slots on the floor. This mechanism of "first delivering air over a long distance within the interlayer, then diffusing it out" effectively overcomes the defect of excessively rapid airflow decay at traditional outlets, greatly expanding the air supply radius of a single unit, achieving wide-area coverage of the large waiting hall space, and avoiding temperature stratification phenomena such as excessively cold near the end and no airflow at the far end.

[0020] 2. The railway station's waiting hall features a large-space ventilation island structure, incorporating unique airflow guiding and noise reduction components (such as spindle-shaped airflow guides, conical airflow guides, or double-layer airflow guides) within the horizontal extension layer. These structures, through S-shaped air ducts and converging dispersion channels, divide and disperse concentrated high-speed airflow into multiple fine airflow streams. As the airflow passes through these labyrinthine channels, its kinetic energy is significantly dissipated, resulting in a low-speed, gentle breeze that ultimately flows out from the floor outlet, perfectly balancing airflow distance and human comfort, and avoiding the discomfort of cold air blowing directly on the head.

[0021] 3. The large-space wind island structure in the waiting hall of this railway station effectively solves the problem of high aerodynamic noise from traditional air conditioning equipment by integrating noise reduction design into the entire air supply process. On the one hand, the airflow guiding and noise reduction components (such as the candy-shaped structure) divide the single large cross-section airflow into countless tiny channels, converting low-frequency roaring sounds into imperceptible high-frequency sounds. On the other hand, as the airflow passes through the airflow guiding and noise reduction channels between the S-shaped air duct, the conical air guide, and the arc-shaped plate, the path is significantly extended and the direction is constantly changed, effectively increasing the sound energy frictional dissipation. This comprehensive approach of dividing the sound source, extending the path, and frictional sound absorption significantly reduces the aerodynamic noise at the air outlet, creating a quieter waiting environment for passengers.

[0022] 4. The railway station waiting hall features a large-space air island structure. Unlike traditional metal air outlets that obstruct the view and light, the extended air curtain components (including horizontal and lateral extensions) in this design are preferably made of transparent materials (such as glass or acrylic panels). This design achieves wide-area air supply without obstructing natural lighting or decorative lighting from the ceiling of the waiting hall, maintaining the openness and visual continuity of the large space, avoiding a feeling of oppression. Furthermore, the transparent umbrella-shaped structure can serve as a unique decorative element, enhancing the interior decoration of the station building and achieving a harmonious unity between electromechanical equipment and architectural aesthetics.

[0048] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0049] The following is in conjunction with the appendix Figure 1 - Appendix Figure 15 The technical solutions provided in the various embodiments of the present invention will be described in detail.

[0050] Example: Refer to Figures 1-4 A large-space wind island structure for a railway station waiting hall includes an island air conditioning unit 1, and further includes: an extended air curtain 11, which is arranged in an umbrella shape on the upper part of the island air conditioning unit 1, and one end is connected to the air outlet of the island air conditioning unit 1, for guiding the air to extend in all directions; the extended air curtain 11 includes a horizontal extension 2 and a lateral extension 30, both of which are provided with a sandwich layer, and the horizontal extension 2 and the lateral extension 30 are connected; a flow guiding and noise reduction component is arranged in the sandwich layer of the horizontal extension 2, for separating, guiding and dissipating airflow; the lateral extension 30 is provided with multiple arc-shaped plates 31, and flow guiding and noise reduction channels 34 are formed between the multiple arc-shaped plates 31.

[0051] The large-space wind island structure in the waiting hall of the railway station provided in this embodiment aims to improve the comfort and acoustic environment quality in a large space through refined airflow organization and noise reduction treatment.

[0052] Specifically, one of the core components of this structure is the island-type air conditioning unit 1. This island-type air conditioning unit 1 is typically a vertical device that integrates air conditioning functional units such as fans and heat exchangers, responsible for generating and delivering temperature- and humidity-controlled air. The air outlet of the island-type air conditioning unit 1 is generally located at its upper part, serving as the airflow source for the entire island structure.

[0053] An extended air curtain 11 is provided at the upper end of the island-type air conditioner body 1. This extended air curtain 11 has an umbrella-shaped structure, with one end connected to the air outlet of the island-type air conditioner body 1. The extended air curtain 11 can be tightly connected to the air outlet of the island-type air conditioner body 1 through mechanical connection or welding to ensure effective airflow. The purpose of this umbrella-shaped structure is to effectively guide the concentrated airflow discharged from the island-type air conditioner body 1, causing it to extend evenly in all directions, thereby expanding the coverage area of ​​the air supply.

[0054] The extended air curtain 11 is further composed of a horizontal extension 2 and a lateral extension 30. The horizontal extension 2 is a polygonal plate-like structure, mainly used for the initial diffusion and guidance of airflow in the horizontal direction. The lateral extension 30 is mainly used to fill the blank area between adjacent horizontal extensions 2, and can be composed of multiple plates or a continuous annular curved surface. Its outer edge is connected to the outer edge of the horizontal extension 2, together forming the umbrella-shaped appearance of the extended air curtain 11.

[0055] Both the horizontal extension 2 and the lateral extension 30 are provided with a sandwich structure. This sandwich structure can be formed by using a double-layer plate structure, that is, by setting two upper and lower plates inside the horizontal extension 2 and the lateral extension 30, thereby forming an internal space between the two plates. This sandwich structure provides an internal channel for airflow and provides space for accommodating subsequent functional components.

[0056] The horizontal extension 2 and the lateral extension 30 are interconnected, allowing airflow to smoothly enter the interlayer of the lateral extension 30 from the interlayer of the horizontal extension 2.

[0057] A flow-guiding and noise-reducing component is provided in the interlayer of the horizontal extension 2. This flow-guiding and noise-reducing component can be composed of a series of flow guides, baffles, or sound-absorbing materials. For example, multiple baffles perpendicular to the airflow direction can be set to divide the airflow into several streams, and the airflow can be guided by changing the flow channel cross-section or increasing the flow channel length; at the same time, sound-absorbing materials can be attached to the flow channel wall or baffles to dissipate the sound energy generated when the airflow passes through, thereby achieving the separation, guidance, and noise reduction of the airflow.

[0058] A flow-guiding and noise-reducing channel 34 is formed between multiple curved plates 31. These channels are the specific paths for airflow within the lateral extension 30. Through the guiding effect of the curved plates 31, the airflow is further dispersed and softened in these channels. At the same time, the curved surface structure of the curved plates 31 also helps to reduce airflow turbulence, thereby further reducing aerodynamic noise and ensuring that the delivered airflow is more uniform and comfortable.

[0059] The proposed air island structure for large-space waiting halls in railway stations effectively solves the technical problems of traditional island air conditioners in large-space environments such as railway station waiting halls, including limited air delivery distance and coverage, poor airflow quality leading to low human comfort, and significant aerodynamic noise. This structure achieves wide-range and uniform airflow delivery, significantly improving the uniformity of temperature distribution in the waiting area. Simultaneously, through a refined airflow guidance and noise reduction mechanism, it effectively reduces airflow noise and softens the feeling of airflow, thus providing passengers with a more comfortable and quiet waiting environment and meeting the needs of refined airflow organization in large-space environments.

[0060] The horizontal extension 2 and the lateral extension 30 can be made of transparent materials, such as glass or acrylic panels. This avoids the horizontal extension 2 and the lateral extension 30 blocking light or sunlight, thus preserving the original lighting design of the waiting hall ceiling and preventing visual oppression. Furthermore, the height of the horizontal extension 2 and the lateral extension 30 should be at least 3 meters above the installation surface, with the specific height adjustable according to actual design requirements. In addition, the horizontal extensions 2 between adjacent island air conditioning units 1 can be connected, allowing the air exhausted from the island air conditioning unit 1 to be further extended and diffused, further improving the soft airflow effect and noise reduction.

[0061] Reference Figure 7 The horizontal extension 2 includes a base plate 20 and an upper cover plate 202, and the lateral extension 30 includes a base plate 3 and an upper cover plate 35. The interlayer is located between the base plate 20 and the upper cover plate 202 and the base plate 3 and the upper cover plate 35, respectively. It also includes an installation arm 201 installed on the island air conditioner body 1. The horizontal extension 2 and the lateral extension 30 are connected to the installation arm 201. The installation arm 201 is a structural component used to securely connect the extended air curtain 11 (including the horizontal extension 2 and the lateral extension 30) to the island air conditioner body 1. The installation arm 201 is usually made of high-strength materials (such as steel or aluminum alloy) and has been structurally optimized to withstand the self-weight of the extended air curtain 11 and the load generated by the airflow. The mounting arm 201 can take various forms, such as multiple support rods, a frame structure, or a cantilever beam. Its quantity and arrangement will be rationally configured according to the size, weight, and stress conditions of the extended air curtain component 11. The connection between the mounting arm 201 and the island air conditioner body 1 can be achieved by bolt fixing, welding, or clipping to ensure a firm and reliable connection. The connection with the horizontal extension component 2 and the lateral extension component 30 must also ensure sufficient strength and stability to prevent the air curtain component from shaking or falling off during use.

[0062] In one implementation, reference Figure 6The airflow guiding and noise reduction assembly includes multiple sets of spindle-shaped airflow guiding and rectifying components 21 installed in the interlayer of the horizontal extension 2, with each set of spindle-shaped airflow guiding and rectifying components 21 staggered. The spindle-shaped airflow guiding and rectifying components 21 are designed with specific geometries to optimize airflow characteristics. These spindle-shaped airflow guiding and rectifying components 21 are installed in multiple sets inside the interlayer of the horizontal extension 2, and their main function is to receive the airflow from the island air conditioning unit 1 and perform preliminary airflow guiding, dispersion, and noise reduction treatment. By staggering the distribution of these spindle-shaped airflow guiding and rectifying components 21, direct airflow impact in a single direction can be avoided, thereby promoting uniform airflow diffusion within the interlayer, reducing airflow resistance, and effectively reducing noise generated by high-speed airflow. This staggered layout helps break the laminar flow state of the airflow, allowing it to mix and disperse over a wider area, laying the foundation for subsequent airflow processing.

[0063] The spindle-shaped airflow guide and rectifier 21 includes a symmetrical streamlined air vane 211. The streamlined air vane 211 is the core component of the spindle-shaped airflow guide and rectifier 21, and its shape design follows aerodynamic principles, exhibiting a symmetrical streamlined shape. This design allows airflow to flow smoothly over the surface of the air vane, minimizing airflow separation and eddy current generation, thereby reducing airflow resistance and improving airflow transmission efficiency. The symmetrical streamlined structure ensures that airflow is uniformly guided and dispersed as it passes through, avoiding directional airflow and contributing to uniform temperature distribution and comfort throughout the air supply area. The streamlined air vane 211 can be made of metal, plastic, or composite materials to meet requirements for strength, corrosion resistance, and lightweight. In this embodiment, to improve the aesthetics of the island air conditioner body 1, a transparent material, such as glass or acrylic sheet, is preferred.

[0064] In addition, the spindle-shaped airflow guide and rectifier 21 also includes open sections 212 located at both ends of the streamlined air vane 211. The open sections 212 are positioned at both ends of the streamlined air vane 211 and function as airflow inlets or outlets, guiding the airflow into or out of the internal structure of the spindle-shaped airflow guide and rectifier 21. The design of these open sections 212 further optimizes the airflow introduction and exit process, ensuring that the airflow can smoothly enter the interior of the spindle-shaped airflow guide and rectifier 21 for processing and, after processing, effectively disperse into the interlayer space of the horizontal extension 2. The shape and size of the open sections 212 can be adjusted according to the required airflow velocity and dispersion effect; for example, they can be designed as flared or tapered sections to achieve the Coanda effect, allowing the airflow to flow along the surface.

[0065] Meanwhile, the spindle-shaped airflow guide and rectifier 21 also includes cylinders 2131 located between the streamlined air vanes 211. The cylinders 2131, positioned between the streamlined air vanes 211, primarily function to further refine the airflow dispersion path and disturb the airflow to promote mixing and energy dissipation. When airflow passes through the area between the streamlined air vanes 211, the presence of the cylinders 2131 forces the airflow to change direction and generates tiny vortices, effectively dispersing the concentrated airflow and making it more evenly distributed. The cylinders 2131 can be solid or hollow, and different diameters and arrangements can be selected according to actual needs.

[0066] Through the above technical solution, multiple sets of staggered spindle-shaped airflow guiding and rectifying components 21 are introduced into the interlayer of the horizontal extension 2. Each component contains symmetrical streamlined air vanes 211, open sections 212 at both ends, and cylinders 2131 between the streamlined air vanes 211. This ingenious structural design allows the high-speed airflow from the island air conditioning unit 1 to be effectively captured and processed in multiple stages by the spindle-shaped airflow guiding and rectifying components 21 after entering the interlayer of the horizontal extension 2. The streamlined air vanes 211 smoothly guide the airflow and reduce resistance, while the open sections 212 ensure smooth airflow entry and exit. The cylinders 2131 agitate and refine the airflow between the air vanes, promoting thorough mixing and energy dissipation. The staggered overall layout further avoids short-circuiting of the airflow and the formation of local high-speed zones, ensuring that the airflow is uniformly dispersed throughout the interlayer of the horizontal extension 2. Therefore, this technical solution significantly improves the uniformity of airflow in large spaces, effectively reduces the noise generated during airflow transmission and dispersion, provides a more comfortable and quiet waiting environment for railway station waiting halls, and improves the overall operating efficiency of the air conditioning system.

[0067] Furthermore, referring to Figure 6 The streamlined air deflector 211 includes a horizontal plate 2111 and an inner curved plate 2112 integrally formed with both ends of the horizontal plate 2111. The open part 212 includes a symmetrically arranged curved plate 2121. A cross-shaped dispersion channel 214 is formed between the open part 212 and the inner curved plate 2112 on one end of the symmetrical streamlined air deflector 211. A central guide channel 213 is formed between the streamlined air deflector 211, the open part 212, and the cylinder 2131. A soft air channel 215 is formed between each group of two adjacent spindle-shaped guide and rectifier parts 21. An S-shaped air channel 216 is formed between the open parts 212 on two groups of adjacent spindle-shaped guide and rectifier parts 21.

[0068] The structure of the streamlined air deflector 211 is further refined, including a horizontal plate 2111 and an inner curved plate 2112 integrally formed with both ends of the horizontal plate 2111. This structural design allows the streamlined air deflector 211 to guide airflow more effectively, and the inner curved plate 2112 helps to produce specific deflection and dispersion effects when the airflow passes through. The opening 212 includes symmetrically arranged curved panels 2121, whose curved surfaces can further guide and shape the airflow, ensuring that the airflow has the expected flow direction and velocity distribution when it leaves the spindle-shaped flow guide 21. In addition, the design of the curved panels 2121 can generate the Coanda effect when the airflow passes through, that is, the airflow can flow along the surface of the curved panels 2121, which can effectively guide the flow direction of part of the airflow.

[0069] The cross-shaped dispersion channel 214 is formed between the open member 212 and the inner curved plate 2112 on one end of the symmetrical streamlined air vane 211. This channel is designed to disperse the incoming airflow in multiple directions, breaking the unidirectional flow pattern. Through this cross-shaped dispersion method, the airflow can diffuse more evenly in all directions within the interlayer of the horizontal extension member 2, preventing airflow from concentrating in specific areas, thereby improving the coverage and uniformity of the airflow. Furthermore, at the cross-shaped dispersion channel 214, the airflow guided by the Coanda effect can converge and be dispersed, further enhancing the coverage and uniformity of the airflow.

[0070] The central guide channel 213 is formed between the streamlined air vane 211, the open section 212, and the cylinder 2131. This guide channel is mainly responsible for guiding the airflow through the central area of ​​the spindle-shaped guide and rectifier 21. Its structural design ensures that the airflow maintains a certain velocity and direction when passing through this area, working synergistically with the airflow passing through the cross-shaped dispersion channel 214 to effectively guide and disperse the airflow. The cylinder 2131, in addition to its structural support function, also participates in the formation of the central guide channel 213, influencing the airflow path.

[0071] The gentle airflow channel 215 is formed between each set of two adjacent spindle-shaped airflow guides 21. The design goal of this channel is to allow the airflow to further mix and diffuse after leaving the spindle-shaped airflow guides 21, creating a gentler and more uniform airflow. By setting such channels between adjacent spindle-shaped airflow guides 21, the impact of the airflow can be effectively reduced, improving the comfort of people in the waiting hall, and also helping to reduce noise generated by high-speed airflow.

[0072] The S-shaped air duct 216 is formed between the open sections 212 on two sets of adjacent spindle-shaped airflow guides 21. The S-shaped design allows most of the airflow to interact with the surface of the open section 212, generating a Coanda effect. This causes the airflow to flow close to the surface of the open section 212, preventing strong airflow from flowing directly out. Furthermore, the airflow undergoes multiple changes in direction and bends. This curved flow path significantly increases the airflow path, promotes thorough mixing, and effectively dissipates the kinetic energy of the airflow, thus achieving a significant noise reduction effect. Simultaneously, the S-shaped air duct 216 also helps to further homogenize the airflow, preventing direct airflow impact and improving overall airflow comfort.

[0073] Through the above technical solution, the internal structure of the spindle-shaped guide and rectifier 21 and the cooperation between adjacent components were meticulously designed. Specifically, the horizontal plate 2111 and the inner curved plate 2112 of the streamlined air vane 211, as well as the curved plate 2121 of the open component 212, together construct a complex internal flow channel. The cross-shaped dispersion channel 214 can disperse the airflow in multiple directions, avoid airflow concentration, and improve the uniformity of airflow coverage. The central guide channel 213 ensures the effective guidance of airflow in the central area. More importantly, by forming a soft wind channel 215 and an S-shaped air duct 216 between adjacent spindle-shaped guide and rectifier components 21, the airflow is not only fully mixed and diffused when passing through the guide and noise reduction components, forming a softer and more uniform air delivery effect, but also the multiple bending paths of the S-shaped air duct 216 significantly increase the friction and energy dissipation of the airflow, thereby effectively reducing airflow noise. These sophisticated flow channel designs enable the entire airflow guidance and noise reduction component to achieve uniform airflow dispersion while significantly improving noise reduction performance, providing a more comfortable and quiet waiting environment for railway station waiting halls.

[0074] Reference Figure 6 Multiple air outlet slots 217 are provided on the base plate 20. The air outlet slots 217 are located between the S-shaped air ducts 216 and between the streamlined air plates 211 that span each set of spindle-shaped guide rectifiers 21.

[0075] The base plate 20 is the lower surface of the horizontal extension 2, on which multiple air outlet slots 217 are formed. These slots are channels through which airflow exits from inside the horizontal extension 2 and enters the waiting hall space. The shape, size, and number of air outlet slots 217 can be optimized according to actual needs, for example, they can be rectangular, circular, or elliptical to achieve specific airflow organization patterns and wind speed distribution. The design of these slots usually needs to consider the principles of fluid mechanics to ensure that the airflow can be discharged smoothly and evenly, avoiding the generation of eddies or local high-speed airflow. Secondly, at the end of the horizontal extension 2 away from the island air conditioning unit 1, that is, at the end of the horizontal extension 2, an exhaust port is also formed to completely exhaust the air in the interlayer of the horizontal extension 2.

[0076] Firstly, the air outlet slot 217 is located between the S-shaped air ducts 216. Since the S-shaped air ducts 216 are formed between the open sections 212 on two adjacent sets of spindle-shaped guide and straightener components 21, their main function is to further guide, disperse, and soften the airflow. Placing the air outlet slot 217 between the S-shaped air ducts 216 means that the airflow processed by the S-shaped air ducts 216 can be directly and smoothly discharged through these slots. This layout ensures that the airflow has been adequately pre-treated before discharge, contributing to a more uniform and gentle airflow effect.

[0077] Secondly, the air outlet slot 217 is also located between the streamlined air vanes 211 spanning each set of spindle-shaped air guides and rectifiers 21. The streamlined air vanes 211 are the core components of the spindle-shaped air guides and rectifiers 21, used to guide airflow. By placing the air outlet slot 217 between the streamlined air vanes 211, the airflow can not only be discharged from the outlet of the S-shaped air duct 216, but also from other areas inside the spindle-shaped air guides and rectifiers 21 (such as the central air guide duct 213 and the soft air duct 215). This multi-point air outlet design further enhances the diffusion range and uniformity of the airflow.

[0078] Through the above technical solution, multiple air outlet slots 217 are opened on the base plate 20 of the horizontal extension 2, and are respectively arranged between the S-shaped air ducts 216 and between the streamlined air plates 211 spanning each set of spindle-shaped guide and rectifier 21. This allows the airflow, after being refined by the spindle-shaped guide and rectifier 21 and its internal complex air ducts (such as the S-shaped air duct 216, the central guide duct 213, the soft air channel 215, and the cross-shaped dispersion channel 214), to be discharged evenly and gently from multiple dispersed outlets. This multi-point, distributed air supply design effectively avoids problems such as excessively strong local airflow, uneven wind speed, or dead air supply that may be caused by traditional single or concentrated air outlets. After being guided and dispersed by the internal airflow guiding and noise reduction components, the airflow enters the waiting hall with lower turbulence and wider coverage through these optimized air outlet slots 217. This significantly improves the uniformity of air distribution in the large space, reduces the discomfort caused by excessive local wind speed, and improves the overall operating efficiency of the air conditioning system and the comfort experience of passengers.

[0079] In one implementation, reference Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 15The airflow guiding and noise reduction component includes multiple sets of conical air guides 22 installed in the interlayer of the horizontal extension 2. Each set of conical air guides 22 is staggered. The conical air guide 22 includes a clamp-type airflow guide and disperser 221 and a symmetrical hook airflow guide and disperser 222. The clamp-type airflow guide and disperser 221 has an air outlet hole 2213, and the symmetrical hook airflow guide and disperser 222 has an air outlet hole 2222.

[0080] The conical air guide 22 is an airflow guiding and dispersing device with a conical or similar conical structure. Installed within the interlayer of the horizontal extension 2, it aims to provide preliminary guidance, dispersion, and noise reduction for the airflow from the island air conditioning unit 1. The staggered distribution of multiple sets of conical air guides 22 avoids direct airflow impact, promotes uniform mixing and diffusion of the airflow, and increases the complexity of the airflow path, thereby effectively dissipating airflow energy and achieving noise reduction. This staggered distribution helps to create a softer, more uniform airflow field, avoiding the generation of localized high-speed airflow areas.

[0081] The clamp-type airflow guide and disperser 221 and the symmetrical hook airflow guide and disperser 222 are the two main components constituting the conical airflow guide 22. They work together to achieve refined airflow guidance and dispersion. The clamp-type airflow guide and disperser 221 has a cross-sectional shape that resembles a "clamp," while the symmetrical hook airflow guide and disperser 222 further guides and disperses the airflow secondary through its unique symmetrical hook shape, ensuring that the airflow can diffuse more evenly when leaving the conical airflow guide 22. This combined design aims to improve the efficiency and uniformity of airflow dispersion.

[0082] Air outlet 2213 is an opening provided on the clamp-type flow guide and disperser 221 to allow a portion of the airflow to flow out from inside the clamp-type flow guide and disperser 221. The size, shape, and distribution of these air outlets 2213 can be optimized according to actual needs to control the outflow speed and direction of the airflow, thereby achieving fine control and dispersion of the airflow. Through these holes, the airflow can be decomposed into multiple smaller airflow streams, further promoting the mixing and uniformity of the airflow.

[0083] Air outlet 2222 is an opening on the symmetrical hook airflow guide and disperser 222. Similar to air outlet 2213, it also guides airflow out of the symmetrical hook airflow guide and disperser 222. These air outlets 2222 work in conjunction with air outlet 2213 on the clamp-type airflow guide and disperser 221 to achieve the final dispersion of airflow. By setting air outlets on different components, multi-level airflow dispersion can be achieved, further improving the uniformity and comfort of airflow and helping to reduce noise caused by airflow impact.

[0084] By setting multiple sets of staggered conical air guides 22 in the interlayer of the horizontal extension 2, and combining them with the clamp-type flow guide and disperser 221 and the symmetrical hook flow guide and disperser 222, as well as the air outlet holes 2213 and 2222 on them, this application can effectively guide, disperse, and dissipate the concentrated airflow from the island air conditioning unit 1 in a multi-level and refined manner. The conical structure and staggered distribution help break the laminar flow state of the airflow and promote turbulent mixing, thereby enabling the airflow to be fully diffused and homogenized inside the horizontal extension 2. The synergistic effect of the clamp-type flow guide and disperser 221 and the symmetrical hook flow guide and disperser 222, as well as the design of their air outlet holes, further decomposes the airflow into multiple gentle airflows, avoiding the direct impact of high-speed airflow and significantly reducing the noise of the airflow during the diffusion process. Therefore, this technical solution ensures that the airflow can extend to all sides in a more uniform and gentle manner, improving the air supply comfort in the large space of the waiting hall and effectively reducing the operating noise of the air conditioning system.

[0085] Reference Figure 11 The clamp-type flow guide and disperser 221 includes a V-shaped plate 2211 and a bend 2212 located at one end of the V-shaped plate 2211; the symmetrical hook flow guide and disperser 222 includes symmetrically arranged hook curved surface parts 2221, the hook curved surface parts 2221 and the bend 2212 bend in the same direction; wherein, a converging dispersion channel 223 is formed between the hook curved surface parts 2221 and the bend 2212, and a converging dispersion channel 224 is formed between the symmetrical hook flow guide and disperser 222 and the converging dispersion channel 223;

[0086] The V-shaped plate 2211, as the core component of the clamp-type airflow guide and disperser 221, effectively diverts the incoming airflow through its V-shaped structure, guiding it to flow in two directions. The bends 2212 at both ends of the V-shaped plate 2211 further guide the diverted airflow, directing it into the subsequent flow channels at specific angles and directions, laying the foundation for refined airflow processing. The hooked surface component 2221 in the symmetrical hook airflow guide and disperser 222, with its symmetrical hook shape design, is designed to work in conjunction with the bend 2212 to shape the airflow path. The hooked surface component 2221 and the bend 2212 share the same bending direction, ensuring a smooth transition and continuous guidance of the airflow between different components, avoiding sudden changes or impacts in the airflow, thereby reducing energy loss and noise generation. The confluence and dispersion channel 223 formed between the hooked surface component 2221 and the bend 2212 is a key area for the initial refined mixing and dispersion of the airflow. Within this channel, the airflow from the V-shaped plate 2211 and bend 2212 converges with the airflow guided by the hook-shaped surface component 2221. Through structural design, weak turbulence or eddies are induced, achieving initial homogenization of the airflow and energy dissipation. Building upon this, a second converging and dispersing channel 224 is further formed between the symmetrical hook-shaped guide and disperser 222 and the first converging and dispersing channel 223. This channel, as a second-level dispersion region, further refines and disperses the airflow after it has been processed by the first converging and dispersing channel 223, further optimizing the airflow uniformity and continuously dissipating the kinetic energy of the airflow to achieve better noise reduction. The design of bend 2212 and the hook-shaped surface component 2221 both generate the Coanda effect during airflow, causing the airflow to conform to the surfaces of bend 2212 and the hook-shaped surface component 2221.

[0087] Through the above technical solution, multi-level converging and dispersing channels 1-223 and 2-224 are constructed by utilizing the synergistic effect of V-shaped plate 2211, bend 1-2212, and hook-shaped curved surface component 2221. This internal structural design allows the high-speed airflow output from the island air conditioning unit 1 to be effectively multi-stage diversion, guidance, mixing, and dissipation when passing through the horizontal extension component 2. The airflow is first initially diverted by V-shaped plate 2211, then guided by bend 1-2212 and hook-shaped curved surface component 2221, undergoing the first fine dispersion and energy dissipation in converging and dispersing channel 1-223, and subsequently undergoing a second, more thorough dispersion and noise reduction process in converging and dispersing channel 2-224. This step-by-step, refined airflow guidance and noise reduction mechanism not only ensures that the speed and direction of the airflow are fully adjusted when entering the large space of the waiting hall, achieving a gentle and uniform air supply effect, effectively avoiding localized strong winds and airflow short-circuiting, and significantly improving the comfort of air supply; at the same time, through the gradual dissipation of airflow kinetic energy through multi-level channels, it greatly reduces the noise generated by airflow friction with structural components and the turbulence of the airflow itself, thereby creating a quiet and comfortable waiting environment for passengers.

[0088] In another implementation, refer to Figure 12 , Figure 13 , Figure 14 The airflow guiding and noise reduction component includes multiple sets of double-layer airflow guiding and dispersing components 23 installed in the interlayer of the horizontal extension component 2. Each set of double-layer airflow guiding and dispersing components 23 is staggered. The double-layer airflow guiding and dispersing components 23 include a small C-shaped body 231 and a large C-shaped body 232. An air outlet slot 234 is provided on the bottom plate 20 between each set of double-layer airflow guiding and dispersing components 23.

[0089] Specifically, this technical solution proposes a double-layer airflow guide and disperser 23, the core of which lies in employing a multi-layer structure to finely guide and disperse airflow. This double-layer design provides a more complex internal flow channel, allowing the incoming airflow to be split, mixed, and redirected multiple times during passage, thereby effectively avoiding direct airflow impact and concentrated airflow, achieving gentle airflow diffusion. The double-layer airflow guide and disperser 23 internally includes small C-shaped bodies 231 and large C-shaped bodies 232, which are key elements for achieving fine airflow control. Through their unique arc-shaped contours, the small C-shaped bodies 231 and large C-shaped bodies 232 can gradually guide high-speed airflow to a preset path and promote airflow exchange and mixing between different layers. This C-shaped design helps to smooth airflow turns, reduce eddy current generation, and thus reduce pressure loss and noise during airflow passage. The size, curvature, and relative position of the small C-shaped bodies 231 and large C-shaped bodies 232 can be optimized according to specific airflow and noise reduction requirements to ensure optimal uniformity and comfort of the airflow when leaving the disperser. Multiple sets of double-layer airflow guiding and dispersing components 23 are staggered within the horizontal extension component 2. This asymmetrical arrangement aims to break the inertia of the straight-line airflow, forcing the airflow to change direction as it passes through different sets of dispersing components, thereby enhancing the mixing effect and spatial diffusion range of the airflow. The staggered distribution effectively prevents the airflow from forming a single, concentrated jet, instead decomposing it into multiple interwoven, gentle airflow bundles, further improving the uniformity of air delivery and helping to achieve temperature and humidity balance over a wider area. Multiple air outlet slots 234 are strategically located between each set of double-layer airflow guiding and dispersing components 23 on the base plate 20. The air outlet slots 234 are the final exits for the airflow processed by the double-layer airflow guiding and dispersing components 23 into the waiting hall. Its position and geometry are designed to ensure that the fully dispersed and noise-reduced airflow can be delivered at a low speed and in a uniform distribution pattern. By placing the air outlet slot 234 between the dispersers, the guiding and mixing effect of the dispersers on the airflow can be maximized, avoiding the airflow from concentrating again at the outlet, thereby ensuring the gentleness of the air supply and further reducing the wind speed and noise at the outlet.

[0090] Through the above technical solution, the airflow guiding and noise reduction component is specifically designed as multiple sets of double-layer airflow guiding and dispersing elements 23, which are staggered in the interlayer of the horizontal extension element 2. Simultaneously, air outlet slots 234 are opened on the base plate 20, which significantly optimizes the airflow characteristics within the horizontal extension element 2. The small C-shaped elements 231 and large C-shaped elements 232 in the double-layer airflow guiding and dispersing elements 23 work together to construct a precise internal flow channel, effectively diverting, guiding, and mixing the incoming airflow, avoiding direct airflow impact and turbulence generation. The staggered distribution further enhances the diffusion and uniformity of the airflow, ensuring the balanced distribution of airflow within the air supply area and effectively eliminating areas of localized overcooling or overheating. Furthermore, as the airflow passes through the complex path of the double-layer airflow guiding and dispersing elements 23, its kinetic energy is gradually dissipated, and the structural surface absorbs and scatters sound waves, thereby significantly reducing airflow noise. Ultimately, the processed, gentle, uniform, and low-noise airflow is smoothly delivered into the waiting hall through the air outlet 234 located between the dispersed components, greatly enhancing the passenger comfort experience and the acoustic quality of the waiting environment.

[0091] Reference Figure 14 The small C-shaped body 231 includes a plate 2311 and curved panels 2312 located at both ends of the plate 2311; the large C-shaped body 232 includes a plate 2321 and side plates 2322 located at both ends of the plate 2321. The plate 2321 has an opening slot 2324. The side plate 2322 has a bend 2323 at the end away from the plate 2321, and the bend 2323 bends toward the curved panel 2312. A flow channel 233 is formed between the side plate 2322, the bend 2323 and the curved panel 2312.

[0092] The small C-shaped body 231 serves as the core internal structure of the double-layer airflow guiding and dispersing component 23. Its plate 2311 is typically a planar or slightly curved surface structure, acting as the main body of the small C-shaped body 231, bearing and guiding the airflow. The curved plate 2312 located at both ends of the plate 2311 further guides and shapes the airflow. Its curved geometry allows the airflow entering the small C-shaped body 231 to be effectively diverted in the initial stage, avoiding direct airflow impact or the formation of vortices, thus laying the foundation for subsequent airflow dispersion. The curvature, length, and angle of the curved plate 2312 can be optimized according to the actual airflow characteristics and dispersion requirements to achieve the best airflow guiding effect.

[0093] The large C-shaped body 232 is another major component of the double-layer airflow guiding and dispersing component 23, typically encasing the smaller C-shaped body 231 and working in conjunction with it. Plate 2321, as the main structure of the large C-shaped body 232, is generally larger in size and shape than plate 2311, forming a larger airflow channel. The side plates 2322 located at both ends of plate 2321 define the lateral boundaries of the airflow and, together with the curved plate 2312 of the smaller C-shaped body 231, construct a fine airflow channel. The side plates 2322 can be designed as straight plates, curved plates, or plates with a specific angle; their main function is to guide the airflow along a predetermined path and provide structural support for airflow dispersion.

[0094] The second plate 2321 has an opening slot 2324, which provides an additional outflow path or diversion point for the airflow. This opening slot 2324 can be one or more holes, gaps, or grilles, and its shape, size, and position can be designed according to the desired airflow dispersion pattern. Through the opening slot 2324, a portion of the airflow can be pre-diverted within the large C-shaped body 232, thereby achieving multi-path, multi-directional airflow dispersion, helping to break the concentrated flow of a single airflow and improve the uniformity and coverage of the airflow.

[0095] The side plate 2322 has a bend 2323 at the end furthest from the plate 2321, and its bending design has an important airflow guiding function. The bending direction of the bend 2323 faces the curved panel 2312 of the small C-shaped body 231, and this relative bending structure forms a convergent or guiding area. This design can effectively guide airflow from the interior of the large C-shaped body 232 to a specific channel between it and the small C-shaped body 231, or further shape and disperse the airflow before it leaves the large C-shaped body 232. The curvature and length of the bend 2323 can precisely control the direction and speed of airflow, thereby optimizing the airflow dispersion effect.

[0096] The diversion channel 233 is a key structure formed by the synergistic action of the small C-shaped body 231 and the large C-shaped body 232. This channel is enclosed by the side plate 2322 and bend 2323 of the large C-shaped body 232, and the curved panel 2312 of the small C-shaped body 231. The diversion channel 233 is designed to control the direction and speed of the airflow, further subdividing the airflow entering the double-layer guide diffuser 23 into multiple sub-airflows. Through the geometry and dimensions of the diversion channel 233, uniform airflow distribution, velocity attenuation, and direction adjustment can be achieved, thereby effectively reducing the impact force of the airflow, reducing noise, and ensuring the gentleness and coverage of the airflow.

[0097] Through the aforementioned technical solution, the structural design of the small C-shaped body 231 and the large C-shaped body 232, especially the synergistic effect of plate 2311, curved panel 2312, plate 2321, side plate 2322, opening slot 2324, and bend 2323, jointly constructs a highly efficient flow-diverting channel 233. This design allows the airflow entering the double-layer flow-guiding and dispersing component 23 to be precisely guided and dispersed in multiple stages and directions. That is, the curved panel 2312 performs initial flow diversion, while the flow-diverting channel 233 formed by the side plate 2322 and bend 2323 of the large C-shaped body 232, together with the curved panel 2312, further refines the airflow path, ensuring that the airflow is sufficiently diffused and its velocity attenuated before leaving the double-layer flow-guiding and dispersing component 23. The opening slot 2324 on plate 2321 provides an additional airflow outlet, further enhancing the airflow dispersion effect. This sophisticated internal structural design effectively solves the problem of uneven airflow guidance and dispersion within the double-layer airflow guide and disperser 23, significantly improving the uniformity and gentleness of the air supply, avoiding discomfort caused to personnel by local high-speed airflow, and effectively reducing the noise generated by the airflow through multi-stage diversion and airflow dissipation, thus providing a more comfortable and quiet air supply environment for the waiting hall of the railway station.

[0098] Reference Figure 7 The mounting arm 201 has multiple interconnecting ports 203, which are connected to the airflow and noise reduction channel 34. The base plate 2 3 has multiple air outlets 32, which are connected to the airflow and noise reduction channel 34. The arc plate 31 has multiple through-holes 33.

[0099] The interchange 203 is an opening provided on the mounting arm 201, whose main function is to serve as a transition interface for airflow from the island air conditioning unit 1 (via the mounting arm 201) into the internal airflow guiding and noise reduction channel 34 of the lateral extension 30. These interchanges 203 can be designed in various geometries, such as circular, square, or slit-shaped, and their number and size can be optimized according to the expected airflow volume and airflow distribution uniformity requirements. Typically, the interchanges 203 are evenly distributed along the length or circumference of the mounting arm 201 to ensure that airflow can be evenly introduced into the airflow guiding and noise reduction channel 34. To reduce airflow resistance and reduce noise generated by local turbulence, the edges of the interchanges 203 can be chamfered or rounded.

[0100] The connection between the interconnection port 203 and the airflow diversion and noise reduction channel 34 is designed to ensure that some of the airflow in the horizontal extension 2 can smoothly and directly enter the airflow diversion and noise reduction channel 34 inside the lateral extension 30 from the mounting arm 201, thereby forming a continuous and efficient airflow transmission path.

[0101] Air outlets 32 are openings located on the base plate 3 of the lateral extension 30. Their function is to effectively deliver the airflow, after being processed inside the airflow guide and noise reduction channel 34, to the waiting hall space. These air outlets 32 can be designed in various forms, such as slits, arrays of circular holes, or grilles. Their distribution density and opening area can be flexibly adjusted according to the specific air supply area requirements. For example, slits evenly distributed along the length of the lateral extension 30 can be used to achieve gentle air supply over a wide area; or circular holes can be concentrated in specific areas to achieve localized enhanced air supply.

[0102] Multiple through-holes 33 are provided on the arc-shaped plate 31. Their core function is to further disperse, mix, and reduce noise in the airflow within the airflow guiding and noise reduction channel 34. These through-holes 33 can be designed in various shapes, such as circular, elliptical, or slit-shaped. These through-holes 33 can effectively promote the lateral flow and thorough mixing of airflow between different arc-shaped plates 31 and within the airflow guiding and noise reduction channel 34, thereby significantly improving the uniformity of airflow. Furthermore, they utilize the orifice effect and frictional resistance to further dissipate airflow energy, achieving a more ideal noise reduction purpose.

[0103] This invention utilizes a refined flow channel design to control airflow within the interlayer. By employing a gradually expanding structure and pressure gradient guidance in the airflow guiding and noise reduction components, eddy current losses and disordered turbulence during airflow delivery are reduced. Airflow is efficiently delivered to the required areas, reducing ineffective energy consumption. Compared to the traditional approach of forcibly extending the air delivery distance by increasing fan power, this solution effectively reduces fan energy consumption while achieving the same or even better coverage, and simultaneously reduces the cost of additional noise reduction treatments due to excessive noise levels.
