Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioning, in particular to a supply air structure, a supply air system and a koji room. BACKGROUND

[0002] The cultural concept of "Koji is the bone of liquor" emphasizes the core position of koji in liquor brewing. As an important auxiliary material for liquor brewing, the quality of koji directly affects the flavor and quality of liquor. Traditional koji is made from moldy or germinated grains. After improvement, the koji industry not only makes breakthroughs in processing technology, but also combines modern scientific technology, especially in precise control of temperature and humidity, greatly improving the quality of koji. Taking Daqu as an example, Daqu is a kind of koji commonly used in distiller's yeast brewing, usually in the shape of bricks. The production process of Daqu includes water soaking, material mixing, and stepping, finally forming a brick-shaped koji block. After that, the koji block is sent to a closed koji room. During the cultivation process, microorganisms multiply and generate heat, which in turn affects the temperature and humidity in the koji room. According to the different cultivation temperatures, Daqu can be divided into medium-high temperature koji (not more than 50℃), high temperature koji (may exceed 50℃) and super-high temperature koji (60-65℃). In the production process of Daqu, the stacking method of the koji block and the metabolism of the strain have a great influence on the temperature, which is an important factor to promote the development of Daqu to high-temperature koji.

[0003] In the traditional production process of Daqu, koji blocks are stacked in the koji room at a certain interval, with a 2-3 cm interval between left and right, and 12 cm thick straw or reed and other materials are laid on each layer of koji block, which helps to maintain temperature and humidity and ensure the quality of koji. In this multi-layer stacking structure, the interval between the koji blocks and the height of the layers are the key to maintaining balanced temperature and humidity. However, despite these measures, the existing technology still faces the problem of uneven temperature distribution.

[0004] Specifically, in a multi-layer stacking environment, the number of koji blocks on the koji rack is large and densely stacked, and the heat dissipation of each koji block is uncontrollable, which leads to temperature differences between koji blocks at different heights, especially between the upper and lower layers. Due to the tightness of the stacking structure, temperature conduction is limited, and local hot spots are easily formed in certain specific locations. The formation of these local hot spots will have a negative impact on the fermentation process of the koji, causing the microorganisms in the area with too high temperature to metabolize too quickly, affecting the fermentation quality of the koji, and thus reducing the overall quality of the koji.

[0005] Although the related art attempts to achieve balanced distribution of temperature by means of temperature sensors, ventilation, air conditioning air supply, etc., the local hot spot problem is still difficult to effectively solve due to the dense stacking between the dough blocks, and at different times, the location of the local hot spot appears at different heights. Therefore, how to eliminate the local hot spot generated at different heights at different times under the condition of multi-layer stacking has become a key technical problem for improving the quality of the wine yeast production. Practical new type content

[0006] In order to solve the above technical problems, the present application provides a kind of air supply structure, air supply system and koji room.

[0012] Further, the air supply section is provided with a plurality of air supply hole areas, and the hole diameters of the air supply holes in the same air supply hole area are the same.

[0013] Further, the hole diameter of the air supply hole gradually decreases along the extension direction of the air supply section.

[0014] Further, along the direction away from the air inlet end, the distribution density of the air supply hole presents the trend of increasing.

[0015] Further, the air supply section is provided with a plurality of air supply hole areas, and the distribution densities of the air supply holes in the same air supply hole area are the same.

[0016] Further, the distribution density of the air supply hole gradually increases along the extension direction of the air supply section.

[0017] Further, the second air valve assembly further comprises a second drive mechanism, and the second drive mechanism is configured to drive the second air valve to move in the air supply section to be close to or away from the first air valve.

[0018] According to a second aspect of the present application, a supply air system is also provided, which comprises an air conditioning unit, a supply air main pipe and the supply air structure provided by the first aspect of the present application, wherein the air inlet end of the supply air branch pipe is in communication with the supply air main pipe, and the air conditioning unit is configured to supply air into the supply air branch pipe through the supply air main pipe.

[0019] According to a third aspect of the present application, a curved room is also provided, which comprises a room body and a curved frame arranged in the room body, and further comprises the supply air system provided by the third aspect of the present application, wherein the air supply section of the supply air branch pipe is located between the curved frames.

[0020] The supply air structure provided by the present application can effectively cope with variable hot spot areas, especially the situation of local hot spots generated at different height areas in the height direction over time, by coordinating the cooperation of the first air valve and the second air valve. By adjusting the position of the first air valve in combination with the adjustment of the opening degree of the first air valve and the second air valve, the range of the air supply area can be regulated.

By adjusting the opening degree of the second air valve to be not 0 and the opening degree of the first air valve to be 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 air supply section and the third air supply section. At this time, when the first air valve is close to the air inlet end, the length of the second air supply section decreases and the air supply area becomes smaller, and when the first air valve is away from the air inlet end, the length of the second air supply section increases and the air supply area increases, thereby accurately regulating the position of the air supply and the area of the air supply. The second air supply section can cope with the air supply and heat dissipation demand when the hot spot is generated at the middle height position, and the air supply amount of the second air supply section can be increased by increasing the opening degree of the second air valve or decreased by decreasing the opening degree of the second air valve, so as to adaptively adjust according to the heat generation of the local hot spot area. The local heat generation area in the space can be targeted for air supply, unnecessary full-area air supply is reduced, cold energy is concentrated in the hot spot area, compared with full-space overall air supply cooling, the local hot spot problem can be quickly solved, the temperature distribution in the space is uniform, the cold energy demand is reduced, the energy saving and carbon reduction goals are achieved. In addition, after the height of the area generating the hot spot changes over time, the height of the air supply area can be changed by adjusting the opening degree of the first air valve and the second air valve and adjusting the position of the first air valve, and the air supply area and the air supply amount can be adjusted to ensure that the temperature of the overall environment remains within the required range.

[0045] In order 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 drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application.

[0050] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0051] According to the description in the background section of the present application, in the related art, local hot spots will be formed at different heights at different times in the environment, and the local hot spots need to be targeted for air supply and heat dissipation. The temperature sensor, ventilation, air conditioning air supply and other means for environmental temperature control often perform overall heat exchange on the temperature in the whole space, and cannot achieve targeted air supply and heat dissipation for the hot spots at specific height positions. Even if the targeted air supply and heat dissipation for the hot spots at specific height positions are achieved, as time goes on, the height of the area where the hot spot is generated will change, and the existing air supply device is difficult to adjust the air supply area in a targeted manner, causing hysteresis and inaccuracy of temperature control.

[0052] Therefore, based on this, the present application provides an air supply structure, as shown in the accompanying drawings, which mainly comprises an air supply branch pipe 100, a first air valve 210 assembly and a second air valve 310 assembly. The air supply structure provided by the present application can be applied to places where the temperature of part of the area needs to be controlled in a targeted manner, such as laboratories, industrial process spaces, storage environments, fungus culture environments and the like, and is especially suitable for local area temperature regulation scenes in spaces where articles are stacked. Figures 1-7

[0053] In the air supply structure, one end of the air supply branch pipe 100 is an air inlet end 110, a part of the air supply branch pipe 100 is formed into an air supply section 120, and a plurality of air supply holes 130 are formed in the pipe wall of the air supply section 120; the first air valve 210 assembly comprises a first driving mechanism and a first air valve 210 arranged in the air supply section 120, and the first driving mechanism is configured to drive the first air valve 210 to move in the air supply section 120 to approach or move away from the air inlet end 110; the second air valve 310 assembly comprises a second air valve 310 arranged in 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.

[0054] ​The air supply section 120 comprises 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 supply section 121 is formed between the first air valve 210 and one end of the air supply section 120 away from the air inlet end 110, the second air supply section 122 is formed between the first air valve 210 and the second air valve 310, and the third air supply section 123 is formed between the second air valve 310 and one 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 according to the positions of the first air valve 210 and the second air valve 310, and the lengths thereof can vary with the positions of the first air valve 210 or the second air valve 310, and the lengths thereof can be 0. For example, when the first air valve 210 is located at one 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 and the second air valve 310 are close together, the length of the second air supply section 122 is 0; and when the second air valve 310 is located at one 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.

[0055] In the present embodiment, the air inlet end 110 of the air supply branch pipe 100 is directly or indirectly connected to an air source device (such as a fan or an air conditioning system). A plurality of air supply holes 130 are formed in the pipe wall of the air supply branch pipe 100, which are used to introduce air in the air supply branch pipe 100 into a specific area outside the pipe. 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 air supply volume.

[0056] The first air valve 210 assembly comprises a first driving mechanism and the first air valve 210 arranged in the air supply section 120. The driving mode of the first driving mechanism includes but is not limited to electric drive, pneumatic drive and hydraulic drive, which is configured to drive the first air valve 210 to reciprocate along the extension direction of the air supply section 120 in the air supply section 120, so as to adjust the position of the first air valve 210 in the air supply section 120, thereby achieving the purpose of adjusting the lengths of the first air supply section 121 and the second air supply section 122. The second air valve 310 assembly comprises the second air valve 310 arranged in the air supply section 120 between the first air valve 210 and the air inlet end 110. The second air valve 310 can further adjust the air flow speed and the air volume by controlling the opening degree, ensuring the flexibility and adaptability of the air supply structure.

[0057] By coordinating the cooperation of the first air valve 210 and the second air valve 310, the variable hot spot area can be effectively dealt with, especially in the case of local hot spots generated at different height areas in the height direction over time. Specifically, by adjusting the position of the first air valve 210 in combination with adjusting the opening of the first air valve 210 and the second air valve 310, the range of the air supply area can be regulated, for example, by adjusting 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 and the first air supply section 121, and the air supply area is only the third air supply section 123, i.e. the highest area position in the figure, which can meet the air supply and heat dissipation demand when a hot spot occurs at a higher position; for example, by adjusting the opening of the second air valve 310 to be not 0 and the opening of the first air valve 210 to be 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, and the area responsible for external air supply is only the second air supply section 122 and the third air supply section 123. At this time, when the first air valve 210 is close to the air inlet end 110, the length of the second air supply section 122 decreases, and the air supply area becomes smaller, and when the first air valve 210 is away from the air inlet end 110, the length of the second air supply section 122 increases, and the air supply area increases, thereby accurately regulating the position and area of the air supply. The second air supply section 122 can meet the air supply and heat dissipation demand when a hot spot occurs at a middle height position, and the air supply amount of the second air supply section 122 can be increased by increasing the opening of the second air valve 310 or decreased by decreasing the opening of the second air valve 310, so as to adaptively adjust according to the heat generation of the local hot spot area.

[0058] Through the air supply structure in the above embodiment, the local heat generation area in the space can be targeted for air supply, unnecessary full-area air supply is reduced, cold energy is concentrated in the hot spot area, compared with full-space whole air supply cooling, the local hot spot problem can be quickly solved, the temperature distribution in the space is uniform, the cold energy demand is reduced, the energy saving and carbon reduction goals are achieved; in addition, after the height of the area where the hot spot occurs changes over time, the opening adjustment of the first air valve 210 and the second air valve 310 and the position adjustment of the first air valve 210 can be used to change the height of the air supply area to the local hot spot, i.e. the embodiment can adapt to the changing hot spot position, adjust the air supply area and the air supply amount over time, and ensure that the temperature of the overall environment remains within the required range.

[0059] From the top to the bottom of the air supply section 120, the total air volume gradually decreases. Under the structural characteristics that the pipe diameter of the air supply section 120 remains unchanged, the air volume of the upper part of the air supply section 120 is large, the flow rate is large, the air supply resistance through the air supply hole 130 is large, the horizontal jet formed has a long distance, a high flow rate, and a large air volume. The air volume of the lower part of the air supply section 120 is small, the flow rate is small, the air supply resistance through the air supply hole 130 is small, the horizontal jet formed has a short distance, a low flow rate, and a small air volume. This causes the air supply volume and the air supply resistance of the air supply section 120 at different heights to be unbalanced, and the air supply effect of the horizontal jet is inconsistent. This imbalance leads to significant differences in the horizontal jet effect at different height positions, affecting the performance and consistency of the air supply structure in specific application scenarios.

[0060] To solve the problem of significant differences in the horizontal jet effect at different height positions caused by the aforementioned imbalance, in an embodiment, the hole diameter of the air supply hole 130 decreases along the direction away from the air inlet end 110. This embodiment can effectively adjust the air supply resistance of the air supply hole 130 at different heights by optimizing the design of the air supply hole 130, thereby achieving uniform distribution of the horizontal jet effect. At the upper part of the air supply section 120, the hole diameter of the air supply hole 130 is larger, and the air supply resistance is appropriately reduced, so that the air volume of the upper region is balanced, and the flow rate and distance of the horizontal jet tend to be moderate. At the lower part of the air supply section 120, the hole diameter of the air supply hole 130 is smaller, and the air supply resistance is appropriately increased, which compensates for the insufficient air volume at the lower part, thereby increasing the flow rate and distance of the horizontal jet. Through the gradual reduction of the hole diameter of the air supply hole 130, a relatively consistent horizontal jet effect can be achieved at different height regions, avoiding the problem of excessive jet at the upper part and insufficient jet at the lower part, and making the horizontal jet distance, flow rate, and air volume at each height region more uniform. Through the above improved design, the air supply structure of the embodiment of the present application can effectively solve the problems of uneven air volume, unbalanced resistance, and inconsistent horizontal jet effect at the upper and lower regions of the air supply section 120, further improving the applicability and stability of the air supply structure in complex scenarios, and achieving energy-efficient temperature control.

[0061] In an optional embodiment, the air supply section 120 can be provided with multiple air supply hole regions, the air supply holes 130 in the same air supply hole region have the same hole diameter, and the hole diameter of the air supply holes 130 in the upper air supply hole region is greater than that of the air supply holes 130 in the lower air supply hole region. For example, two layers of air supply hole regions are adopted, the air supply holes 130 with large hole diameter are adopted in the upper air supply hole region of the air supply section 120, and the air supply holes 130 with small hole diameter are adopted in the lower air supply hole region of the air supply section 120; for example, three layers of air supply hole regions are adopted, the air supply holes 130 with large hole diameter are adopted in the upper air supply hole region of the air supply section 120, the air supply holes 130 with medium hole diameter are adopted in the middle air supply hole region of the air supply section 120, and the air supply holes 130 with small hole diameter are adopted in the lower air supply hole region of the air supply section 120. In this embodiment, the air supply section 120 is divided into multiple air supply hole regions, the air supply holes 130 in each layer of air supply hole region have the same hole diameter, but the hole diameter gradually decreases layer by layer between different air supply hole regions. By changing the number of layers and the hole diameter of each layer, the air supply performance can be flexibly adjusted, the uniformity of the air supply amount at different heights is improved, the multi-level air supply demand is met, the design and manufacturing difficulty of the air supply section 120 is simplified, and the production cost is reduced.

[0062] In an optional embodiment, the hole diameter of the air supply hole 130 gradually decreases along the extension direction of the air supply section 120. For example, the hole diameter of the air supply hole 130 uniformly decreases along the axial direction of the air supply section 120, and the change of the hole diameter of the air supply hole 130 can be designed according to the following formula: d(x) = d0-kx, wherein d(x) is the hole diameter of the air supply hole 130 at a position x away from the air supply hole 130 closest to the air inlet end 110, d0 is the hole diameter of the air supply hole 130 closest to the air inlet end 110, and k is the hole diameter change rate. By adjusting the size of k, the speed of hole diameter reduction can be flexibly controlled to meet the air supply demand of different scenes. In this embodiment, the change of the hole diameter of the air supply hole 130 can be designed according to the decreasing rule, which can ensure that the air volume and resistance of the horizontal air supply jet gradually adjust along the extension direction of the air supply section 120, provide more delicate air supply adjustment, avoid the distribution discontinuity caused by layering, and further optimize the air supply uniformity at different heights.

[0063] To solve the problem of the significant difference in the horizontal jet effect at different height positions caused by the aforementioned unevenness, in another embodiment, the distribution density of the air supply holes 130 presents an increasing trend in the direction away from the air inlet end 110. This embodiment can effectively adjust the air supply resistance of the air supply holes 130 at different heights by optimizing the distribution density of the air supply holes 130, thereby achieving uniform distribution of the horizontal jet effect. At the upper part of the air supply section 120, the air supply amount and the air supply resistance are appropriately reduced due to the lower density of the air supply holes 130, so that the air volume of the upper region is balanced, and the horizontal jet flow rate and distance tend to be moderate. At the lower part of the air supply section 120, the air supply amount and the air supply resistance are appropriately increased due to the greater density of the air supply holes 130, which compensates for the insufficient air volume of the lower part, thereby increasing the horizontal jet flow rate and distance. Through the design of gradually increasing the distribution density of the air supply holes 130, relatively consistent horizontal jet effects can be achieved at different height regions, avoiding the problem of excessive jet at the upper part and insufficient jet at the lower part, so that the horizontal jet distance, flow rate, and air volume at each height region are more uniform. Through the above improved design, the air supply structure of the embodiment of the present application can effectively solve the problems of uneven air volume, unbalanced resistance, and inconsistent horizontal jet effect at the upper and lower regions of the air supply section 120, further improving the applicability and stability of the air supply structure in complex scenarios, while achieving energy-efficient temperature control.

[0064] In an optional embodiment, the air supply section 120 can be provided with multiple air supply hole regions, the distribution density of the air supply holes 130 in the same air supply hole region is the same, and the distribution density of the air supply holes 130 in the upper air supply hole region is less than that in the lower air supply hole region. For example, two layers of air supply hole regions are adopted, the number of air supply holes 130 per unit area in the upper air supply hole region of the air supply section 120 is less, and the number of air supply holes 130 per unit area in the lower air supply hole region of the air supply section 120 is more. For example, three layers of air supply hole regions are adopted, the number of air supply holes 130 per unit area in the upper air supply hole region of the air supply section 120 is less, the number of air supply holes 130 per unit area in the middle air supply hole region of the air supply section 120 is more, and the number of air supply holes 130 per unit area in the lower air supply hole region of the air supply section 120 is the most. In this embodiment, the air supply section 120 is divided into multiple air supply hole regions, and the air supply holes 130 in each layer of air supply hole region have the same distribution density, but the distribution density of the air supply holes 130 gradually decreases layer by layer between different air supply hole regions. The number of layers and the size of the distribution density in each layer can be changed to flexibly adjust the air supply performance, improve the uniformity of the air supply amount at different height regions, adapt to multi-level air supply demand, simplify the design and manufacturing difficulty of the air supply section 120, and reduce production costs.

[0065] In optional embodiments, 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 uniformly increases along the axial direction of the air supply section 120. In this embodiment, the change in the distribution density of the air supply holes 130 presents an increasing regular design, which can ensure that the air volume and resistance of the horizontal air supply jet gradually adjust along the extension direction of the air supply section 120, provide more delicate air supply adjustment, avoid the discontinuity problem caused by stratification, and further optimize the air supply uniformity at different heights.

[0066] In some embodiments, the second air valve 310 assembly further comprises a second driving 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 driving mode of the second driving mechanism includes but is not limited to electric driving, pneumatic driving, and hydraulic driving, which is configured to drive the second air valve 310 to reciprocally move within the air supply section 120 along the extension direction of the air supply section 120, so as to adjust the position of the second air valve 310 within the air supply section 120, thereby achieving the purpose of adjusting the length of the second air supply section 122 and the length of the third air supply section 123. The provision of the second driving mechanism can further improve the flexibility and targeted regulation ability of the air supply structure. Specifically, the movement of the second air valve 310 changes the length of the second air supply section 122 and the third air supply section 123: when the second air valve 310 approaches 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 of the proximal region and reducing the air supply range of the middle region; when the second air valve 310 moves 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 of the middle region and reducing the air supply range of the proximal region. Over time, the height of the hot spot region can change, and through the coordinated cooperation of the first air valve 210 and the second air valve 310, the moving position and the opening degree of both can be adjusted, so that the air supply range and the air supply volume of the first air supply section 121, the second air supply section 122, and the third air supply section 123 can be adjusted, precise positioning of the air supply region is achieved, and the air supply range and the air supply volume are concentrated in the height region where the current hot spot is located. This is particularly suitable for scenarios where the height of the hot spot changes constantly, ensuring that the air supply structure can quickly respond and maintain the balance of the ambient temperature.

[0067] In some embodiments, the first driving mechanism comprises a rotary actuator 220 and a telescopic pull rod 230, one end of the telescopic pull rod 230 is matched with the rotary actuator 220, and the other end is connected with the first air valve 210, the rotary actuator 220 is used to drive the telescopic pull rod 230 to realize telescopic movement, so as to drive the first air valve 210 to reciprocate in the air supply section 120. The rotary actuator 220 is a power output component for driving the telescopic pull rod 230 to move, including but not limited to a stepper motor; one end of the telescopic pull rod 230 is matched with the rotary actuator 220, and the other end is fixedly connected with the first air valve 210, and is responsible for converting the driving force of the rotary actuator 220 into the linear telescopic movement of itself. The telescopic pull 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 with the telescopic pull rod 230, moves along the axial direction of the air supply section 120 through the linear telescopic movement of the telescopic pull rod 230, so as to adjust the length and range of each air supply area. The movement direction and speed of the telescopic pull rod 230 can be accurately adjusted according to the control parameters of the rotary actuator 220. When the telescopic pull rod 230 is elongated, the first air valve 210 is away from the air inlet end 110 of the air supply section 120, so that the length of the first air supply section 121 is reduced, and the length of the second air supply section 122 is increased; when the telescopic pull rod 230 is contracted, the first air valve 210 is close to the air inlet end 110 of the air supply section 120, so that the length of the first air supply section 121 is increased, and the length of the second air supply section 122 is reduced. The combination of the rotary actuator 220 and the telescopic pull rod 230 is simple and compact, the telescopic pull rod 230 can extend in the axial direction in the air supply branch pipe 100, is easy to integrate into the air supply structure and has small resistance to airflow.

[0068] In some embodiments, the first driving mechanism comprises a rotary actuator 220 and a roller screw, the roller screw comprises a threaded shaft and a nut, and the core function is to convert the rotary movement of the rotary actuator 220 into the linear movement of the nut, the roller screw has the advantages of high transmission efficiency and low friction loss, and can ensure the movement 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 installed on the nut of the roller screw, the rotary actuator 220 drives the threaded shaft of the roller screw to rotate, and the roller 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 roller screw transmission system has high transmission efficiency and positioning accuracy, and can meet the fine adjustment and control requirements of the position of the first air valve 210. The combination of the rotary actuator 220 and the roller screw is simple and compact, the roller screw can extend in the axial direction in the air supply branch pipe 100, is easy to integrate into the air supply structure and has small resistance to airflow.

[0069] 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.

[0070] 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.

[0071] This application also provides an air supply system, such as... Figures 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 210 assembly, and a second air valve 310 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 210 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 310 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] The application further provides a method for controlling air supply, which is implemented by the air supply structure provided by the preceding embodiments of the application. The air supply structure mainly comprises an air supply branch pipe 100, a first air valve 210 assembly and a second air valve 310 assembly. One end of the air supply branch pipe 100 is an air inlet end 110. A part of the air supply branch pipe 100 is formed into an air supply section 120. A plurality of air supply holes 130 are formed in the pipe wall of the air supply section 120. The first air valve 210 assembly comprises a first driving mechanism and a first air valve 210 arranged in the air supply section 120. The first driving mechanism is configured to drive the first air valve 210 to move in the air supply section 120 to approach or move away from the air inlet end 110. The second air valve 310 assembly comprises a second air valve 310 arranged 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 one end of the air supply section 120 away from the air inlet end 110. A second air supply section 122 is formed between the first air valve 210 and the second air valve 310. A third air supply section 123 is formed between the second air valve 310 and one end of the air supply section 120 away from the air inlet end 110.

[0076] The method for controlling air supply comprises controlling the opening degrees of the first air valve 210 and the second air valve 310 and controlling the movement of the first air valve 210 in the air supply section 120 to adjust the length of the first air supply section 121 and the length of the second air supply section 122.

[0077] The method is applicable to the air supply structure described in the preceding embodiments. By dynamically adjusting the air supply area and the air volume, the local hot spots in the space can be accurately regulated. In the control method, real-time temperature data can be obtained by sensors distributed in the target environment, the position and degree of local hot spots or temperature abnormal areas can be identified, the range of the required air supply area and the corresponding air supply volume can be determined, and a regulation strategy can be generated. The specific regulation measures are to control the opening degrees of the first air valve 210 and the second air valve 310 and control the movement of the first air valve 210 in the air supply section 120 to realize accurate air supply regulation. When air supply needs to be concentrated to the third air supply section 123, as shown in FIG. 6, the opening degree of the second air valve 310 is adjusted to a small value or even 0, so that the airflow only acts on the third air supply section 123 at the top area of the air supply section 120. Figure 2 Figure 3 ​As shown, the second air valve 310 is adjusted to be properly opened, and the opening of the first air valve 210 is adjusted to be a smaller value or even 0 according to the demand, so that the air outlet range is concentrated in the second air supply section 122 and the third air supply section 123, and the air supply amount distribution of the second air supply section 122 and the third air supply section 123 can be controlled through 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 amount. When it is needed to reduce the air supply proportion of the second air supply section 122, the opening of the second air valve 310 can be correspondingly reduced. Figure 4 As shown, the first air valve 210 and the second air valve 310 are adjusted to be opened, so that 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, and the air supply amount distribution of the first air supply section 121, the second air supply section 122 and the third air supply section 123 can be controlled through the openings of the first air valve 210 and the second air valve 310. When the openings of the first air valve 210 and the second air valve 310 are 100%, the first air supply section 121 can obtain the maximum air supply amount. When it is needed to reduce the air supply proportion of the first air supply section 121, the openings of the first air valve 210 and the second air valve 310 can be correspondingly reduced.

[0078] The first air valve 210 is moved along the air supply section 120 by the first driving mechanism, so as to adjust the lengths of the first air supply section 121 and the second air supply section 122. When the 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 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, and the opening of the first air valve 210 is adjusted to be 0, so as to perform targeted air supply on the local hot spot, that is, as shown. Figure 3 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 123 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, and the opening of the first air valve 210 is adjusted to be not 0, so as to perform targeted air supply on the local hot spot, that is, as shown. Figure 4

[0079] The method can update the two air valve openings and the first air valve 210 position in real time as the hot spot area position changes, so as to ensure that the air supply area coverage range matches the hot spot area. The method effectively solves the problem that the local hot spot cannot be accurately controlled in the traditional air supply mode, and has the characteristics of flexible regulation and control, rapid response and strong adaptability, and provides a reliable solution for realizing precise environment control.

[0080] The environment parameters after air supply regulation and control can also be fed back in real time by the sensor, and the regulation and control effect can be evaluated. If it is found that the temperature still does not meet the target range, the openings and positions of the two air valves are further optimized to form a closed-loop control.​

[0081] On the basis of the above-mentioned embodiments, the second air valve 310 assembly further comprises a second driving mechanism configured to drive the second air valve 310 to move in the air supply section 120 to approach or move away from the first air valve 210. The air supply control method further comprises: controlling the first air valve 210 and the second air valve 310 to move in the air supply section 120 to adjust the length of the first air supply section 121, the length of the second air supply section 122, and the length of the third air supply section 123. The provision of the second driving mechanism can further improve the flexibility and targeted regulation 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 approaches 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 of the proximal region and reducing the air supply range of the middle region; when the second air valve 310 moves 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 of the middle region and reducing the air supply range of the proximal region. Over time, the height of the hot spot region can change, and through the coordinated movement of the first air valve 210 and the second air valve 310, the movement position and the opening degree of both can be adjusted, so that the air supply range and the air supply amount of the first air supply section 121, the second air supply section 122, and the third air supply section 123 can be adjusted, precise positioning of the air supply region is achieved, and the air supply range and the air supply amount are concentrated in the height region where the current hot spot is located. It is particularly suitable for scenarios where the height of the hot spot changes constantly, ensuring that the air supply structure can respond quickly and maintain the balance of the environment temperature.

[0082] The air supply control method provided by the embodiments of the present application has a whole air supply mode, a layered air supply mode, and a single-layer air supply mode.

[0083] In some embodiments, the air supply control method of the whole air supply mode comprises: Figure 5 As shown, the opening degrees of the first air valve 210 and the second air valve 310 are fully opened. By fully opening the opening degrees of the two air supply valves, the air supply amount of the two air valves is not adjusted, and the whole air supply section 120 is used for air supply. Along the direction away from the air inlet end 110, the hole diameter of the air supply hole 130 presents a decreasing trend, and the distribution density of the air supply hole 130 presents an increasing trend. According to the design of the hole diameter and the density of the air supply hole 130 around the air supply section 120, the air supply amount and the air supply resistance at different heights of the air supply section 120 are regulated to meet the whole air supply and air flow organization requirements in the environment.

[0084] On the basis of the above-mentioned embodiments, the whole air supply mode further comprises: Figure 6As shown, the first air valve 210 is controlled to be located at an end of the air supply section 120 away from the air inlet end 110, and the length of the first air supply section 121 is 0. This control mode makes the first air valve 210 completely located at the distal end of the air supply section 120. Although the first air valve 210 in the fully open state can allow the airflow to pass through to the maximum extent, the airflow will inevitably be physically blocked to a certain extent by the first air valve 210 during the passing process. Moving the first air valve 210 to the end of the air supply section 120 away from the air inlet end 110 can make the airflow flow unobstructed in the air supply section 120.

[0085] Based on the same reason, when the second air valve 310 is movable, the whole air supply mode further includes: Figure 6 As shown, the second air valve 310 is controlled to be located at an end of the air supply section 120 close to the air inlet end 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 both ends of the air supply section 120 respectively, and the second air supply section 122 is the whole air supply range.

[0086] In some embodiments, the air supply control method in the layered air supply mode includes: Figure 4 As shown, the opening degrees of the first air valve 210 and the second air valve 310 are controlled to be between 0-100%; and the position of the first air valve 210 in the air supply section 120 is adjusted so that the lengths of the first air supply section 121 and the second air supply section 122 are both greater than 0. By moving the first air valve 210 axially along the air supply section 120 through the first driving mechanism, the lengths of the first air supply section 121 and the second air supply section 122 can be adjusted. When the 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 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, and the opening degree of the first air valve 210 is adjusted to 0, which can supply air to the local hot spot. 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, and the opening degree of the first air valve 210 is adjusted to be not 0, which can supply air to the local hot spot.

[0087] On the basis of the above-mentioned embodiments, the second air valve 310 assembly further comprises a second driving mechanism configured to drive the second air valve 310 to move in the air supply section 120 to approach or move away from the first air valve 210. The air supply control method in the layered air supply mode further comprises: adjusting the positions of the first air valve 210 and the second air valve 310 in the air supply section 120, so that at least two of the length of the first air supply section 121, the length of the second air supply section 122, and the length of 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, the moving positions and the opening degrees of both can be adjusted, so that the air supply ranges and the air supply amounts of the first air supply section 121, the second air supply section 122, and the third air supply section 123 can be adjusted, the air supply area can be accurately positioned, and the air supply range and the air supply amount can be concentrated in the height area where the current hot spot is located.

[0088] In some embodiments, the air supply control method in the single-layer air supply mode comprises: 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 in 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, the third air supply section 123 cannot supply air, and 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, so that only the second air supply section 122 is used for single-layer air supply. Through the position adjustment of the first air valve 210, the second air supply section 122 with different lengths can be obtained, and the purpose of adjusting the single-layer air supply range is achieved.

[0089] In this specification, some embodiments are described in a progressive or parallel manner, and each embodiment focuses on the difference from other embodiments. The same or similar parts between the embodiments can be referred to each other.
