Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and in particular to an air supply structure, air supply system, ventilation room, and air supply control method. Background Technology

[0002] The cultural concept of "qu (fermentation starter) is the backbone of wine" emphasizes the core position of qu in brewing. As an important auxiliary material in brewing, the quality of qu directly affects the flavor and quality of the wine. Traditionally, qu was made from moldy or sprouted grains. After improvements, the qu industry has not only made breakthroughs in processing technology but also incorporated modern science and technology, especially in the precise control of temperature and humidity, which has greatly improved the quality of qu. Taking daqu as an example, daqu is a type of qu commonly used in distilled spirits and is usually made into brick shapes. The production process of daqu includes steps such as moistening, mixing, and treading, ultimately forming brick-shaped qu blocks. Afterward, the qu blocks are sent to a sealed qu room. During the cultivation process, microorganisms multiply rapidly and generate heat, which in turn affects the temperature and humidity inside the qu room. Depending on the cultivation temperature, daqu can be divided into medium-high temperature qu (not exceeding 50℃), high temperature qu (exceeding 50℃), and ultra-high temperature qu (60-65℃). In the production process of daqu, the stacking method of the qu blocks and the influence of microbial metabolism on temperature are important factors driving the development of high-temperature qu.

[0003] In traditional Daqu (a type of starter culture) production, the starter culture blocks are stacked at specific intervals in the fermentation room, maintaining a 2-3 cm gap between each side. A 12 cm thick layer of straw or reeds is laid on top of each layer of starter culture blocks to help maintain temperature and humidity, ensuring the quality of the starter culture. In this multi-layered stacking structure, the spacing between the starter culture blocks and the height of each layer are crucial for maintaining a balanced temperature and humidity. However, despite these measures, existing technologies still face the problem of uneven temperature distribution.

[0004] Specifically, in multi-layered stacking environments, the large number and dense stacking of koji blocks on the racks, coupled with the uncontrollable heat dissipation of each block, leads to temperature differences between blocks at different heights, particularly between the upper and lower layers. Due to the compact stacking structure, heat conduction is restricted, easily creating localized hotspots in certain locations. These hotspots negatively impact the koji fermentation process, causing excessively rapid microbial metabolism in overheated areas, affecting the fermentation quality of the koji and thus reducing its overall quality.

[0005] Although related technologies employ environmental control methods such as temperature sensors, ventilation, and air conditioning to attempt to achieve a more even temperature distribution, the problem of localized hot spots remains difficult to effectively address due to the dense stacking of the yeast starter blocks. Furthermore, these hot spots can appear at different heights at different times. Therefore, eliminating localized hot spots at varying heights during multi-layered stacking has become a key technical challenge for improving the quality of yeast starter production. Summary of the Invention

[0006] To address the aforementioned technical problems, this application provides an air supply structure, an air supply system, a curved room, and an air supply control method.

[0007] According to a first aspect of this application, embodiments of this application provide an air supply structure, which includes:

[0008] An air supply branch pipe, one end of which is an air inlet, has an air supply section formed on the pipe wall with several air supply holes.

[0009] The first air valve assembly includes a first drive mechanism and a first air valve disposed within the air supply section. The first drive mechanism is configured to drive the first air valve to move within the air supply section to approach or move away from the air inlet.

[0010] The second air valve assembly includes a second air valve disposed within the air supply section, the second air valve being located between the first air valve and the air inlet.

[0011] Furthermore, along the direction away from the air inlet, the diameter of the air outlet tends to decrease.

[0012] Furthermore, the distribution density of the air outlets increases along the direction away from the air inlet.

[0013] Furthermore, the second air valve assembly also includes a second drive mechanism configured to drive the second air valve to move within the air supply section to approach or move away from the first air valve.

[0014] According to a second aspect of this application, an air supply system is also provided, the air supply system including an air conditioning unit, an air supply main pipe and the air supply structure provided in the first aspect of this application, wherein the air inlet end of the air supply branch pipe is connected to the air supply main pipe, and the air conditioning unit is configured to supply air to the air supply branch pipe through the air supply main pipe.

[0015] According to a third aspect of this application, a curved room is also provided, which includes a room body and curved frames disposed within the room body, and further includes the air supply system provided in the third aspect of this application, wherein the air supply section of the air supply branch pipe is located between the curved frames.

[0016] According to a fourth aspect of this application, this application also provides an air supply control method, which is implemented by the air supply structure provided in the first aspect of this application. A first air supply section is formed between a first air valve and the end of the air supply section furthest from the air inlet end; a second air supply section is formed between the first air valve and a second air valve; and a third air supply section is formed between the second air valve and the end of the air supply section closest to the air inlet end. The air supply control method includes:

[0017] The opening degree of the first air valve and the second air valve is controlled, and the first air valve is controlled to move within the air supply section to adjust the length of the first air supply section and the length of the second air supply section.

[0018] Furthermore, the air supply control method further includes:

[0019] The first air valve and the second air valve are controlled to move within the air supply section to adjust the length of the first air supply section, the length of the second air supply section, and the length of the third air supply section.

[0020] Furthermore, the air supply control method has an overall air supply mode, which includes:

[0021] Control the opening degree of the first air valve and the second air valve to be fully open.

[0022] Furthermore, the overall air supply mode also includes: controlling the first air valve to be located at the end of the air supply section away from the air inlet end, and the length of the first air supply section is 0.

[0023] Furthermore, the air supply control method has a tiered air supply mode, which includes:

[0024] The opening degree of both the first and second air valves is controlled to be between 0-100%.

[0025] Adjust the position of the first air valve within the air supply section so that the length of both the first and second air supply sections is greater than 0.

[0026] Furthermore, the stratified air supply mode also includes:

[0027] Adjust the positions of the first air valve and the second air valve within the air supply section so that at least two of the lengths of the first air supply section, the second air supply section, and the third air supply section are greater than 0.

[0028] Furthermore, the air supply control method has a single-layer air supply mode, which includes:

[0029] Control the opening degree of the first air valve to 0, and control the opening degree of the second air valve to be greater than 0;

[0030] Adjust the positions of the first air valve and the second air valve within the air supply section so that the length of the second air supply section is greater than 0 and the length of the third air supply section is 0.

[0031] The air supply structure provided in this application, by coordinating the cooperation of the first and second air valves, can effectively cope with variable hotspot areas, especially when localized hotspots arise at different heights over time. By adjusting the position of the first air valve in conjunction with adjusting the openings of the first and second air valves, the range of the air supply area can be controlled. By adjusting the opening of the second air valve to 0, the airflow in the third air supply section cannot enter the second and first air supply sections, and the air supply area is only the third air supply section, which can meet the air supply and heat dissipation needs when hotspots are generated at higher positions. By adjusting the opening of the second air valve to not be 0, and the opening of the first air valve to 0, the airflow in the third air supply section can enter the second air supply section, but cannot enter the first air supply section, and the area responsible for external air supply is only the second and first air supply sections. In the third air supply section, when the first air valve is close to the air inlet, the length of the second air supply section decreases, and the air supply area becomes smaller. Conversely, when the first air valve is far from the air inlet, the length of the second air supply section increases, and the air supply area increases. This allows for precise control of the air supply position and area. The second air supply section can address the heat dissipation needs when hot spots are generated in the middle height area. Furthermore, the air supply volume of the second air supply section can be increased by increasing the opening of the second air valve, or decreased by decreasing the opening of the second air valve, to achieve adaptive adjustments based on the heat generation of local hot spots. It can target localized heat-generating areas in a space, reducing unnecessary general airflow and concentrating cooling capacity on hot spots. Compared to general airflow cooling throughout the entire space, it can quickly resolve localized hot spot issues, achieving uniform temperature distribution while reducing cooling demand and achieving energy conservation and carbon reduction goals. Furthermore, as the height of hot spots changes over time, the height of the airflow area can be adjusted to align with the localized hot spots by regulating the opening of the first and second air valves and the position of the first air valve. This allows for adjustments to the airflow area and volume, ensuring that the overall ambient temperature remains within the required range. Attached Figure Description

[0056] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

For example, a system, product or device that includes a series of units is not necessarily limited to those units that are explicitly listed, but may include units that are not explicitly listed or that are inherent to such products or devices.

These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0060] Furthermore, the terms "set up," "connect," and "fix" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0061] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0062] As described in the background section of this application, in related technologies, localized hotspots may form at different heights in the environment at different times, requiring targeted airflow for heat dissipation. Methods of controlling ambient temperature through temperature sensors, ventilation, and air conditioning often involve overall heat exchange across the entire space, failing to provide targeted airflow for heat dissipation to hotspots at specific heights. Even if targeted airflow is achieved for hotspots at specific heights, the height of the hotspot area changes over time, making it difficult for existing airflow devices to adjust the airflow area accordingly, resulting in lag and inaccuracy in temperature control.

[0063] Based on this, embodiments of this application provide an air supply structure, such as... Figure 1-7 As shown, the air supply structure mainly includes an air supply branch pipe 100, a first air valve assembly, and a second air valve assembly. The air supply structure provided in this embodiment can be applied to places where targeted temperature control of certain areas is required, such as laboratories, industrial process spaces, storage environments, and fungal culture environments, and is especially suitable for localized temperature control scenarios in spaces where items are stacked.

[0064] In the air supply structure, one end of the air supply branch pipe 100 is the air inlet end 110, and a part of the air supply branch pipe 100 is formed as an air supply section 120. A plurality of air supply holes 130 are opened on the pipe wall of the air supply section 120. The first air valve assembly includes a first driving mechanism and a first air valve 210 disposed in the air supply section 120. The first driving mechanism is configured to drive the first air valve 210 to move within the air supply section 120 to approach or move away from the air inlet end 110. The second air valve assembly includes a second air valve 310 disposed in the air supply section 120. The second air valve 310 is located between the first air valve 210 and the air inlet end 110.

[0065] The air supply section 120 includes a first air supply section 121, a second air supply section 122, and a third air supply section 123 connected in sequence. Specifically, the first air valve 210 forms the first air supply section 121 with the end of the air supply section 120 away from the air inlet end 110, the first air valve 210 forms the second air supply section 122 with the second air valve 310, and the second air valve 310 forms the third air supply section 123 with the end of the air supply section 120 close to the air inlet end 110. It should be noted that the first air supply section 121, the second air supply section 122, and the third air supply section 123 are divided into air supply sections 120 according to the positions of the first air valve 210 and the second air valve 310. Their lengths may vary with the position of the first air valve 210 or the second air valve 310, and their lengths can be 0. For example, when the first air valve 210 is located at the end of the air supply section 120 away from the air inlet end 110, the length of the first air supply section 121 is 0. When the first air valve 210 is close to the second air valve 310, the length of the second air supply section 122 is 0. When the second air valve 310 is located at the end of the air supply section 120 close to the air inlet end 110, the length of the third air supply section 123 is 0.

[0066] In this embodiment, the air inlet 110 of the air supply branch duct 100 is directly or indirectly connected to an air source device (such as a fan or air conditioning system). Several air supply holes 130 are formed on the wall of the air supply branch duct 100. These air supply holes 130 are used to introduce air from inside the air supply branch duct 100 to a specific area outside the duct. The length of the air supply section 120 and the number and size of the air supply holes 130 can be designed and adjusted according to actual needs to ensure the spatial distribution of the air supply volume.

[0067] The first air valve assembly includes a first drive mechanism and a first air valve 210 disposed within the air supply section 120. The first drive mechanism can be driven, but is not limited to, by electric drive, pneumatic drive, and hydraulic drive. It is configured to drive the first air valve 210 to reciprocate along the extension direction of the air supply section 120 within the air supply section 120, thereby adjusting the position of the first air valve 210 within the air supply section 120, thus achieving the purpose of adjusting the length of the first air supply section 121 and the second air supply section 122. The second air valve assembly includes a second air valve 310, which is disposed within the air supply section 120 and located between the first air valve 210 and the air inlet end 110. The second air valve 310 can further adjust the airflow speed and volume by controlling its opening degree, ensuring the flexibility and adaptability of the air supply structure.

[0068] By coordinating the operation of the first air valve 210 and the second air valve 310, the system can effectively address variable hotspot areas, especially localized hotspots that may appear at different heights over time. Specifically, by adjusting the position of the first air valve 210 in conjunction with adjusting the openings of both the first and second air valves 310, the range of the air supply area can be controlled. For example, by setting the opening of the second air valve 310 to 0, the airflow in the third air supply section 123 cannot enter the second air supply section 122 or the first air supply section 121; the air supply area is limited to the third air supply section 123, i.e., the highest area in the diagram, thus meeting the cooling needs when hotspots appear at higher locations. Conversely, by adjusting the opening of the second air valve 310 to a non-zero value and setting the opening of the first air valve 210 to 0, the airflow in the third air supply section 123 can enter the second air supply section 122 but cannot enter the first air supply section 121, thus controlling the external air supply. The area consists only of the second air supply section 122 and the third air supply section 123. When the first air valve 210 is close to the air inlet 110, the length of the second air supply section 122 decreases, and the air supply area becomes smaller. When the first air valve 210 is far away from the air inlet 110, the length of the second air supply section 122 increases, and the air supply area increases. This allows for precise control of the air supply position and area. The second air supply section 122 can meet the air supply and heat dissipation needs when hot spots are generated at the middle height position. The air supply volume of the second air supply section 122 can be increased by increasing the opening of the second air valve 310, or the air supply volume of the second air supply section 122 can be reduced by decreasing the opening of the second air valve 310, so as to achieve adaptive adjustment according to the heat generation of the local hot spot area.

[0069] Through the air supply structure in the above embodiments, targeted air supply can be provided to localized hot areas in the space, reducing unnecessary whole-area air supply and concentrating cooling capacity on hot spots. Compared with whole-space overall air supply cooling, it can quickly solve local hot spot problems, achieve uniform temperature distribution in the space, reduce cooling demand, and achieve energy saving and carbon reduction goals. In addition, as the height of the hot spot area changes over time, the height of the air supply area relative to the local hot spot can be changed by adjusting the opening of the first air valve 210 and the second air valve 310, as well as adjusting the position of the first air valve 210. That is, this embodiment can adapt to the constantly changing hot spot position and adjust the air supply area and air volume over time to ensure that the overall ambient temperature remains within the required range.

[0070] From top to bottom of the air supply section 120, the total air volume gradually decreases. With the duct diameter of the air supply section 120 remaining constant, the upper part of the air supply section 120 has a large air volume and velocity, resulting in high airflow resistance through the air supply holes 130, and thus a horizontal jet with a long distance, high velocity, and large air volume. Conversely, the lower part of the air supply section 120 has a small air volume and velocity, resulting in low airflow resistance through the air supply holes 130, and thus a horizontal jet with a short distance, low velocity, and low air volume. This imbalance in air supply volume and airflow resistance at different heights of the air supply section 120 leads to inconsistent horizontal jet delivery effects. This imbalance results in significant differences in the horizontal jet effect at different heights, affecting the performance and consistency of the air supply structure in specific application scenarios.

[0071] To address the significant differences in horizontal jet effects at different heights caused by the aforementioned imbalance, in one embodiment, the diameter of the air supply orifice 130 decreases along the direction away from the air inlet 110. This embodiment, by optimizing the design of the air supply orifice 130, effectively adjusts the air supply resistance at different heights, thereby achieving a uniform distribution of the horizontal jet effect. In the upper part of the air supply section 120, due to the larger diameter of the air supply orifice 130, the air supply resistance is appropriately reduced, balancing the airflow in the upper region and resulting in a moderate horizontal jet velocity and distance. In the lower part of the air supply section 120, due to the smaller diameter of the air supply orifice 130, the air supply resistance is appropriately increased, compensating for insufficient airflow in the lower part and thus improving the horizontal jet velocity and distance. Through the gradually decreasing diameter design of the air supply orifice 130, a relatively consistent horizontal jet effect can be achieved in different height regions, avoiding the problem of excessively strong upper jet and insufficient lower jet, resulting in more uniform horizontal jet distance, velocity, and airflow in each height region. Through the above-mentioned improved design, the air supply structure of this application embodiment can effectively solve the problems of uneven air volume, unbalanced resistance, and inconsistent horizontal jet effect in the upper and lower areas of the air supply section 120, further improving the applicability and stability of the air supply structure in complex scenarios, while achieving energy-saving and efficient temperature control.

[0072] In an optional embodiment, the air supply section 120 can be provided with multiple air supply hole areas, where the air supply holes 130 within the same air supply hole area have the same diameter, and the diameter of the air supply holes 130 in the upper air supply hole area is larger than that in the lower air supply hole area. For example, a two-layer air supply hole area can be used, with large-diameter air supply holes 130 in the upper air supply hole area of ​​the air supply section 120 and small-diameter air supply holes 130 in the lower air supply hole area of ​​the air supply section 120; or, for example, a three-layer air supply hole area can be used, with large-diameter air supply holes 130 in the upper air supply hole area of ​​the air supply section 120, medium-diameter air supply holes 130 in the middle air supply hole area of ​​the air supply section 120, and small-diameter air supply holes 130 in the lower air supply hole area of ​​the air supply section 120. In this embodiment, the air supply section 120 is divided into multiple air supply hole areas. The air supply holes 130 in each air supply hole area have the same aperture, but the apertures between different air supply hole areas decrease layer by layer. By changing the number of layers and the aperture size of each layer, the air supply performance can be flexibly adjusted. This improves the uniformity of air supply volume in different height areas and adapts to the needs of multi-level air supply. At the same time, it simplifies the design and manufacturing difficulty of the air supply section 120 and reduces production costs.

[0073] In an optional implementation, the diameter of the air supply hole 130 gradually decreases along the extension direction of the air supply section 120. For example, the diameter of the air supply hole 130 can be uniformly distributed along the axial direction of the air supply section 120. The diameter change of the air supply hole 130 can be designed according to the following formula: d(x) = d0 - kx, where d(x) is the diameter of the air supply hole 130 at position x closest to the air inlet end 110; d0 is the diameter of the air supply hole 130 closest to the air inlet end 110; and k is the diameter change rate. By adjusting the value of k, the rate of diameter reduction can be flexibly controlled to meet the air supply requirements of different scenarios. In this implementation, the diameter change of the air supply hole 130 can be designed in a decreasing pattern, which can ensure that the air volume and resistance of the horizontal air jet are gradually adjusted along the extension direction of the air supply section 120, providing more delicate air supply adjustment, avoiding the problem of discontinuous distribution caused by stratification, and further optimizing the air supply uniformity at different heights.

[0074] To address the significant differences in horizontal jet effects at different heights caused by the aforementioned imbalance, in another embodiment, the distribution density of the air supply holes 130 increases along the direction away from the air inlet 110. This embodiment, by optimizing the distribution density of the air supply holes 130, can effectively adjust the air supply resistance at different heights, thereby achieving a uniform distribution of the horizontal jet effect. In the upper part of the air supply section 120, due to the lower density of the air supply holes 130, the air volume and air supply resistance are appropriately reduced, balancing the air volume in the upper region and making the horizontal jet velocity and distance more moderate. In the lower part of the air supply section 120, due to the higher density of the air supply holes 130, the air volume and air supply resistance are appropriately increased, compensating for the insufficient air volume in the lower part, thereby improving the horizontal jet velocity and distance. By gradually increasing the distribution density of the air outlets 130, a relatively consistent horizontal jet effect can be achieved in different height areas, avoiding the problem of excessive upper jet and insufficient lower jet, thus making the horizontal jet distance, velocity, and air volume more uniform in each height area. Through the above-mentioned improved design, the air supply structure of this embodiment can effectively solve the problems of uneven air volume, unbalanced resistance, and inconsistent horizontal jet effect in the upper and lower areas of the air supply section 120, further improving the applicability and stability of the air supply structure in complex scenarios, while achieving energy-saving and efficient temperature control.

[0075] In an optional implementation, the air supply section 120 can be provided with multiple air supply hole areas, with the distribution density of air supply holes 130 within the same air supply hole area being the same. The distribution density of air supply holes 130 in the upper air supply hole area is less than that in the lower air supply hole area. For example, using a two-layer air supply hole area, the number of air supply holes 130 per unit area is less in the upper air supply hole area of ​​the air supply section 120, while the number of air supply holes 130 per unit area is more in the lower air supply hole area of ​​the air supply section 120. As another example, using a three-layer air supply hole area, the number of air supply holes 130 per unit area is less in the upper air supply hole area of ​​the air supply section 120, the number of air supply holes 130 per unit area is more in the middle air supply hole area of ​​the air supply section 120, and the number of air supply holes 130 per unit area is the largest in the lower air supply hole area of ​​the air supply section 120. In this embodiment, the air supply section 120 is divided into multiple air supply hole areas. The air supply holes 130 in each air supply hole area have the same density, but the density of the air supply holes 130 between different air supply hole areas decreases layer by layer. By changing the number of layers and the size of the density of distribution in each layer, the air supply performance can be flexibly adjusted. This improves the uniformity of air supply volume in different height areas and adapts to the needs of multi-level air supply. At the same time, it simplifies the design and manufacturing difficulty of the air supply section 120 and reduces production costs.

[0076] In an optional embodiment, the distribution density of the air supply holes 130 gradually increases along the extension direction of the air supply section 120. For example, the distribution density of the air supply holes 130 increases uniformly along the axial direction of the air supply section 120. In this embodiment, the design of the increasing distribution density of the air supply holes 130 ensures that the air volume and resistance of the horizontal air jet are gradually adjusted along the extension direction of the air supply section 120, providing more delicate air supply adjustment, avoiding discontinuity problems caused by stratification, and further optimizing the uniformity of air supply at different heights.

[0077] In some embodiments, the second air valve assembly further includes a second drive mechanism configured to drive the second air valve 310 to move within the air supply section 120 to approach or move away from the first air valve 210. The drive mechanism can be driven by, but is not limited to, electric, pneumatic, and hydraulic methods. It is configured to drive the second air valve 310 to reciprocate along the extension direction of the air supply section 120 within the air supply section 120, thereby adjusting the position of the second air valve 310 within the air supply section 120, and thus achieving the purpose of adjusting the length of the second air supply section 122 and the third air supply section 123. The provision of the second drive mechanism can further enhance the flexibility and targeted control capability of the air supply structure. Specifically, the movement of the second air valve 310 changes the lengths of the second air supply section 122 and the third air supply section 123: when the second air valve 310 is close to the first air valve 210, the length of the second air supply section 122 decreases and the length of the third air supply section 123 increases, thereby increasing the air supply range in the near-end area and decreasing the air supply range in the middle area; when the second air valve 310 is far away from the first air valve 210, the length of the second air supply section 122 increases and the length of the third air supply section 123 decreases, thereby increasing the air supply range in the middle area and decreasing the air supply range in the near-end area. As time goes by, the height of the hot spot area may change. Through the coordinated operation of the first air valve 210 and the second air valve 310, the movement position and opening degree of both can be adjusted, so that the air supply range and air volume of the first air supply section 121, the second air supply section 122 and the third air supply section 123 can be adjusted. This achieves precise positioning of the air supply area and ensures that the air supply range and air volume are concentrated in the height area where the current hot spot is located. It is especially suitable for scenarios where the height of the hot spot is constantly changing, ensuring that the air supply structure can respond quickly and maintain a balanced ambient temperature.

[0078] In some embodiments, the first driving mechanism includes a rotary actuator 220 and a telescopic rod 230. One end of the telescopic rod 230 engages with the rotary actuator 220, and the other end is connected to the first air valve 210. The rotary actuator 220 drives the telescopic rod 230 to achieve telescopic movement, thereby causing the first air valve 210 to reciprocate within the air supply section 120. The rotary actuator 220 is the power output component that drives the telescopic rod 230, including but not limited to a stepper motor. One end of the telescopic rod 230 engages with the rotary actuator 220, and the other end is fixedly connected to the first air valve 210, responsible for converting the driving force of the rotary actuator 220 into its own linear telescopic movement. The telescopic rod 230 can be a single-axis telescopic rod, a double-axis telescopic rod, or a sliding rod with guide rail assistance to ensure smooth movement. The first air valve 210 is connected to the telescopic rod 230, and moves along the axial direction of the air supply section 120 through the linear telescopic movement of the telescopic rod 230, thereby adjusting the length and range of each air supply area. The direction and speed of the telescopic rod 230 can be precisely adjusted according to the control parameters of the rotary actuator 220. When the telescopic rod 230 extends, the first air valve 210 moves away from the air inlet end 110 of the air supply section 120, reducing the length of the first air supply section 121 and increasing the length of the second air supply section 122. When the telescopic rod 230 retracts, the first air valve 210 moves closer to the air inlet end 110 of the air supply section 120, increasing the length of the first air supply section 121 and decreasing the length of the second air supply section 122. The combined design of the rotary actuator 220 and the telescopic rod 230 is simple and compact. The telescopic rod 230 can extend axially within the air supply branch pipe 100, making it easy to integrate into the air supply structure and having minimal obstruction to airflow.

[0079] In some embodiments, the first drive mechanism includes a rotary actuator 220 and a lead screw. The lead screw includes a threaded shaft and a nut, and its core function is to convert the rotational motion of the rotary actuator 220 into the linear motion of the nut. The lead screw has the advantages of high-efficiency transmission and low friction loss, which can ensure the motion accuracy and stability of the first air valve 210. The length and pitch of the threaded shaft can be adjusted according to the specific design requirements of the air supply section 120. The first air valve 210 is fixedly mounted on the nut of the lead screw. The rotary actuator 220 drives the threaded shaft of the lead screw to rotate, and the lead screw drives the first air valve 210 to reciprocate along the axial direction of the air supply section 120 through the linear movement of the nut. The lead screw transmission system has high transmission efficiency and positioning accuracy, which can meet the requirements for fine control of the position of the first air valve 210. The combination design of the rotary actuator 220 and the lead screw is simple and compact. The lead screw can extend axially within the air supply branch pipe 100, which is easy to integrate into the air supply structure and has little obstruction to airflow.

[0080] In addition, the first drive mechanism can also be a combination of gears and racks, a combination of gears and timing belts, a combination of gears and chains, a linear motor drive, etc. Those skilled in the art can make adaptive adjustments and rotations according to the application scenario and requirements.

[0081] It should be noted that the configuration of the second drive mechanism can refer to the structure and working principle of the first drive mechanism, and will not be elaborated further.

[0082] This application also provides an air supply system, such as... Figure 1-8 As shown, the air supply system includes an air conditioning unit (not shown), a main air supply pipe 400, and the air supply structure provided in the foregoing embodiments of this application. The air supply structure mainly includes a branch air supply pipe 100, a first air valve assembly, and a second air valve assembly. One end of the branch air supply pipe 100 is an air inlet end 110, and a portion of the branch air supply pipe 100 is formed as an air supply section 120. Several air supply holes 130 are opened on the pipe wall of the air supply section 120. The first air valve assembly includes a first driving mechanism and a first air valve 210 disposed within the air supply section 120. The first driving mechanism is configured to drive the first air valve 210 to move within the air supply section 120 to approach or move away from the air inlet end 110. The second air valve assembly includes a second air valve 310 disposed within the air supply section 120, and the second air valve 310 is located between the first air valve 210 and the air inlet end 110. The air inlet 110 of the air supply branch duct 100 is connected to the air supply main duct 400, and the air conditioning unit is configured to supply air to the air supply branch duct 100 through the air supply main duct 400.

[0083] The air conditioning unit, as an air source device, is responsible for delivering air through the main air supply pipe 400 to the branch air supply pipe 100. The air conditioning unit provides the required airflow and quality to the air supply system by regulating parameters such as temperature, humidity, and airflow velocity. The main air supply pipe 400 connects the air conditioning unit to the branch air supply pipe 100, and its task is to deliver the air processed by the air conditioning unit to the branch air supply pipe 100. Depending on the requirements, the duct design of the main air supply pipe 400 can accommodate different airflow and pressure requirements.

[0084] The air conditioning unit supplies air to the branch duct 100 via the main air supply pipe 400, which in turn introduces the air into the air supply section 120. Within the air supply section 120, air is discharged through air outlets 130 located at different positions to supply specific areas. The airflow, velocity, and volume distribution within the air supply section 120 are adjusted according to demand. Through the cooperation of the first damper 210 and the second damper 310, the air supply system can adjust the air supply height, velocity, and volume in real time according to changes in hotspot areas. For example, when the location of a hotspot area changes, the cooperation of the first damper 210 and the second damper 310 can respond quickly, ensuring that the hotspot area receives sufficient heat dissipation and cooling.

[0085] This application also provides a curved room, such as Figure 8 As shown, the fermentation room includes a room body 500, fermentation racks 600 disposed within the room body 500, and the air supply system provided in the aforementioned embodiments of this application. The air supply sections 120 of the air supply branch pipes 100 are located between the fermentation racks 600. The fermentation racks 600, as supporting structures for stacking fermented koji, typically employ a multi-layered structure to meet the requirement of multi-layer stacking of koji, ensuring a suitable spatial layout for the koji during fermentation. The air supply sections 120 of the air supply branch pipes 100 are located between the fermentation racks 600. The air supply system, through precise control of the air supply area and air volume, effectively targets and dissipates heat from localized hot spots at different heights within the fermentation room, ensuring uniform fermentation of the koji. In this embodiment, the design of the air supply system considers the characteristics of koji stacking within the fermentation racks 600, particularly the fact that different layers of koji may experience localized hot spots during fermentation due to temperature and humidity changes. By setting multiple air outlets 130 on the air supply branch pipe 100, and combining the regulating action of the first air valve 210 assembly and the second air valve 310 assembly, the air supply area and air volume are dynamically adjusted, thereby specifically controlling temperature anomalies in local areas within the fermentation room and preventing uneven temperature from affecting the fermentation effect of the yeast. By integrating the air supply system into the structural design of the fermentation room, the fermentation efficiency of the yeast can be effectively improved, the quality stability of the yeast can be guaranteed, and a more precise temperature management solution can be provided for yeast production.

[0086] This application also provides an air supply control method, which is implemented by the air supply structure provided in the foregoing embodiments of this application. The air supply structure mainly includes an air supply branch pipe 100, a first air valve assembly, and a second air valve assembly. One end of the air supply branch pipe 100 is an air inlet end 110, and a portion of the air supply branch pipe 100 is formed as an air supply section 120. A plurality of air supply holes 130 are opened on the pipe wall of the air supply section 120. The first air valve assembly includes a first driving mechanism and a first air valve 210 disposed in the air supply section 120. The first driving mechanism is configured to drive the first air valve 210 to move within the air supply section 120 to approach or move away from the air inlet end 110. The second air valve assembly includes a second air valve 310 disposed in the air supply section 120. The second air valve 310 is located between the first air valve 210 and the air inlet end 110. A first air supply section 121 is formed between the first air valve 210 and the end of the air supply section 120 away from the air inlet 110; a second air supply section 122 is formed between the first air valve 210 and the second air valve 310; and a third air supply section 123 is formed between the second air valve 310 and the end of the air supply section 120 away from the air inlet 110.

[0087] The air supply control method includes: controlling the opening degree of the first air valve 210 and the second air valve 310, and controlling the first air valve 210 to move within the air supply section 120, so as to adjust the length of the first air supply section 121 and the length of the second air supply section 122.

[0088] This method is applicable to the air supply structure described in the foregoing embodiments. By dynamically adjusting the air supply area and air volume, it achieves precise control of local hot spots within the space. In this control method, real-time temperature data can be acquired through sensors distributed in the target environment to identify the location and severity of local hot spots or abnormal temperature areas, determine the range of the required air supply area and the corresponding air volume, and generate a control strategy. Specifically, the control measures involve controlling the opening of the first air valve 210 and the second air valve 310, and controlling the movement of the first air valve 210 within the air supply section 120 to achieve precise air supply control. When concentrated air supply to the third air supply section 123 is required, such as... Figure 2 As shown, the opening of the second air valve 310 is adjusted to a small value or even 0, so that the airflow only acts on the top area of ​​the third air supply section 123 of the air supply section 120. When air needs to be supplied to the second air supply section 122 and the third air supply section 123, as follows: Figure 3 As shown, the second air valve 310 is adjusted to open appropriately, and the opening of the first air valve 210 is adjusted to a smaller value or even 0 as needed, so that the air outlet range is concentrated in the second air supply section 122 and the third air supply section 123. The air supply volume distribution between the second air supply section 122 and the third air supply section 123 can be controlled by the opening of the second air valve 310. When the opening of the second air valve 310 is 100%, the second air supply section 122 can obtain the maximum air supply volume. When it is necessary to reduce the air supply ratio of the second air supply section 122, the opening of the second air valve 310 can be reduced accordingly. When air needs to be supplied to the first air supply section 121, as... Figure 4 As shown, by adjusting the opening of both the first air valve 210 and the second air valve 310, the air outlet range is distributed in the first air supply section 121, the second air supply section 122, and the third air supply section 123. The air supply volume distribution of the first air supply section 121, the second air supply section 122, and the third air supply section 123 can be controlled by adjusting the opening of the first air valve 210 and the second air valve 310. When the opening of the first air valve 210 and the second air valve 310 is 100%, the first air supply section 121 can obtain the maximum air supply volume. When it is necessary to reduce the air supply ratio of the first air supply section 121, the opening of the first air valve 210 and the second air valve 310 can be reduced accordingly.

[0089] The first drive mechanism moves the first air valve 210 axially along the air supply section 120, adjusting the lengths of the first air supply section 121 and the second air supply section 122. When a local hot spot is located below the second air valve 210 and at a higher position, the length of the second air supply section 122 is adjusted by moving the first air valve 210, so that the range of the second air supply section 122 corresponds to the position of the local hot spot. By adjusting the opening of the first air valve 210 to 0, targeted air supply can be provided to the local hot spot. Figure 3 As shown. When the local hot spot is located below the second air valve 310 and at a lower position, the length of the first air supply section 121 is adjusted by moving the first air valve 210 so that the range of the first air supply section 121 corresponds to the position of the local hot spot. By adjusting the opening of the first air valve 210 to not be zero, targeted air supply can be provided to the local hot spot, as shown. Figure 4 As shown.

[0090] This method can update the opening of the two air valves and the position of the first air valve 210 in real time as the location of the hot spot changes, ensuring that the coverage of the air supply area matches the hot spot area. It effectively solves the shortcomings of traditional air supply methods in accurately controlling local hot spots, while also featuring flexible adjustment, rapid response, and strong adaptability, providing a reliable solution for achieving precise environmental control.

[0091] The system can also use sensors to provide real-time feedback on environmental parameters after air supply regulation, allowing for evaluation of the regulation effect. If the temperature still does not meet the target range, the opening and position of the two air valves can be further optimized to form a closed-loop control.

[0092] Based on the above embodiment, the second air valve assembly further includes a second drive mechanism, which is configured to drive the second air valve 310 to move within the air supply section 120 to approach or move away from the first air valve 210. The air supply control method further includes controlling the movement of the first air valve 210 and the second air valve 310 within the air supply section 120 to adjust the lengths of the first air supply section 121, the second air supply section 122, and the third air supply section 123. The second drive mechanism further enhances the flexibility and targeted control capability of the air supply structure. Specifically, the movement of the second air valve 310 changes the lengths of the second air supply section 122 and the third air supply section 123: when the second air valve 310 is close to the first air valve 210, the length of the second air supply section 122 decreases and the length of the third air supply section 123 increases, thereby increasing the air supply range in the near-end area and decreasing the air supply range in the middle area; when the second air valve 310 is far away from the first air valve 210, the length of the second air supply section 122 increases and the length of the third air supply section 123 decreases, thereby increasing the air supply range in the middle area and decreasing the air supply range in the near-end area. As time goes by, the height of the hot spot area may change. Through the coordinated operation of the first air valve 210 and the second air valve 310, the movement position and opening degree of both can be adjusted, so that the air supply range and air volume of the first air supply section 121, the second air supply section 122 and the third air supply section 123 can be adjusted. This achieves precise positioning of the air supply area and ensures that the air supply range and air volume are concentrated in the height area where the current hot spot is located. It is especially suitable for scenarios where the height of the hot spot is constantly changing, ensuring that the air supply structure can respond quickly and maintain a balanced ambient temperature.

[0093] The air supply control method provided in this application embodiment has an overall air supply mode, a layered air supply mode, and a single-layer air supply mode.

[0094] In some implementations, the air supply control method for the overall air supply mode includes: such as Figure 5 As shown, the opening degrees of the first air valve 210 and the second air valve 310 are fully open. With both air supply valves fully open, no airflow adjustment is performed, and the entire air supply section 120 is used for air supply. Along the direction away from the air inlet 110, the diameter of the air supply holes 130 tends to decrease, while the distribution density of the air supply holes 130 tends to increase. Based on the design of the diameter and density of the air supply holes 130 around the air supply section 120, the airflow and air resistance at different heights of the air supply section 120 are adjusted to meet the overall air supply and airflow organization requirements of the environment.

[0095] Based on the above implementation method, the overall air supply mode further includes: Figure 6As shown, the first air valve 210 is controlled to be located at the end of the air supply section 120 away from the air inlet 110, and the length of the first air supply section 121 is 0. This control method makes the first air valve 210 completely located at the far end of the air supply section 120. Although the first air valve 210 being fully open allows the airflow to pass through to the maximum extent, the airflow will inevitably be physically blocked by the first air valve 210 to a certain extent during the process of passing through the first air valve 210. Moving the first air valve 210 completely to the end of the air supply section 120 away from the air inlet 110 allows the airflow to flow unimpeded in the air supply section 120.

[0096] Based on the same principle, when the second air valve 310 is movable, the overall air supply mode also includes: Figure 6 As shown, the second air valve 310 is positioned at the end of the air supply section 120 near the air inlet 110, and the length of the third air supply section 123 is 0. At this time, the first air valve 210 and the second air valve 310 are located at the two ends of the air supply section 120, and the second air supply section 122 is the entire air supply range.

[0097] In some implementations, the air supply control method in the stratified air supply mode includes: such as Figure 4 As shown, the opening degrees of both the first air valve 210 and the second air valve 310 are controlled to be between 0% and 100%. The position of the first air valve 210 within the air supply section 120 is adjusted so that the lengths of both the first air supply section 121 and the second air supply section 122 are greater than 0. The lengths of the first air supply section 121 and the second air supply section 122 can be adjusted by moving the first air valve 210 axially along the air supply section 120 via the first drive mechanism. When a local hot spot is located below the second air valve 310 and at a higher position, the length of the second air supply section 122 can be adjusted by moving the first air valve 210 so that the range of the second air supply section 122 corresponds to the position of the local hot spot. By adjusting the opening degree of the first air valve 210 to 0, targeted air supply can be provided to the local hot spot. When the local hot spot is located below the second air valve 310 and at a low position, the length of the first air supply section 121 can be adjusted by moving the first air valve 210 so that the range of the first air supply section 121 corresponds to the position of the local hot spot, and the opening of the first air valve 210 can be adjusted to be non-zero, so that targeted air supply can be provided to the local hot spot.

[0098] Based on the above embodiment, the second air valve 310 assembly further includes a second driving mechanism, which is configured to drive the second air valve 310 to move within the air supply section 120 to approach or move away from the first air valve 210. The air supply control method in the stratified air supply mode further includes adjusting the positions of the first air valve 210 and the second air valve 310 within the air supply section 120, such that at least two of the lengths of the first air supply section 121, the second air supply section 122, and the third air supply section 123 are greater than 0. Through the coordinated operation of the first air valve 210 and the second air valve 310, their movement positions and opening degrees can be adjusted, allowing the air supply range and volume of the first air supply section 121, the second air supply section 122, and the third air supply section 123 to be adjusted, achieving precise positioning of the air supply area and ensuring that the air supply range and volume are concentrated in the height area where the current hotspot is located.

[0099] In some implementations, the air supply control method for a single-layer air supply mode includes: such as Figure 7 As shown, the opening degree of the first air valve 210 is controlled to be 0, and the opening degree of the second air valve 310 is controlled to be greater than 0. The positions of the first air valve 210 and the second air valve 310 within the air supply section 120 are adjusted so that the length of the second air supply section 122 is greater than 0, and the length of the third air supply section 123 is 0. Since the length of the third air supply section 123 is 0, it cannot supply air. Since the opening degree of the first air valve 210 is 0, the airflow cannot enter the first air supply section 121, and the first air supply section 121 also cannot supply air. This results in single-layer air supply only through the second air supply section 122. By adjusting the position of the first air valve 210, different lengths of the second air supply section 122 can be obtained, thereby achieving the purpose of adjusting the single-layer air supply range.
