[0036] Please refer to the attached Figure 1 and the attached Figure 2 An embodiment of the present utility model provides an air supply system, which includes an air supply module 10. The air supply module 10 includes an air supply fan 11, an air duct 12 and a plurality of air outlets 13. Specifically, the air duct 12 is communicated with the air supply fan 11, and the plurality of air outlets 13 are arranged on the side wall 14 of the air duct 12. Each air outlet 13 is correspondingly arranged with a target position in the air duct 12, and the air outlets 13 corresponding to different target positions have different opening ratios, so that the same air supply volume can be obtained in different areas. Further explanation is that the number of air supply fans 11 can be one or more, which is selected according to specific requirements and will not be specifically limited here. In a specific example, the air supply module 10 includes an air supply fan 11 and a plurality of air outlets 13 located below the air supply fan 11, and the plurality of air outlets 13 are arranged at intervals in the longitudinal direction. It can be explained that the opening ratio is the ratio of the opening area of the air outlet 13 to the total area. By differentiating the opening ratios of the respective air outlets 13, the air supply volume in different areas can be controlled, ensuring uniform air volume distribution in the whole system and avoiding the problem of excessive or insufficient air volume in some areas. This design is not only applicable to the industrial and agricultural fields, but also can be applied to the air conditioning and ventilation systems of commercial and residential buildings. In a specific application scenario, such as the air conditioning system of a large building, the air supply module 10 can be installed on the ceiling or under the floor. By setting a plurality of air outlets 13 and differentiating the opening ratios of the plurality of air outlets 13, the temperature and air circulation in each room or area are made uniform, so that the environment in the whole building is more comfortable.

[0037] The air supply system of the present utility model includes an air supply module 10. The air supply module 10 includes an air supply fan 11, an air duct 12 and a plurality of air outlets 13. Among them, the air duct 12 is communicated with the air supply fan 11, and the plurality of air outlets 13 are arranged on the side wall 14 of the air duct 12. Each air outlet 13 is correspondingly arranged with a target position in the air duct 12, and the air outlets 13 corresponding to different target positions have different opening ratios. Through the differential design of the opening ratios of the air outlets 13 corresponding to different target positions, the same air supply volume can be obtained in each area as much as possible, effectively avoiding the problem of excessive or insufficient air volume in some areas.

[0038] In some alternative embodiments, the air supply system includes a plurality of independently arranged air supply modules 10, which are spaced apart and installed in the temperature and humidity regulation chamber. Each air supply module 10 has the same air supply volume. Among them, the specific structure of each air supply module 10 is the same, that is, each air supply module 10 includes the same number of air supply fans 11, air outlets 13 and air ducts 12, and the models of the air supply fans 11 are the same. The arrangements of the air outlets 13 with different opening ratios are the same, and the sizes and shapes of the air ducts 12 are also the same. The temperature and humidity regulation chamber can be an agricultural breeding and scientific research laboratory. In this embodiment, by installing a plurality of air supply modules 10 in the temperature and humidity regulation chamber, each air supply module 10 can operate independently without interference and has the same air supply volume, so as to achieve the effect of uniform air supply in different regions and realize the control of the uniformity of temperature and humidity in the temperature and humidity regulation chamber.

[0039] In some alternative embodiments, the opening ratio of the air outlet 13 is inversely proportional to the static pressure value in the air duct 12. This means that when the static pressure value in the air duct 12 is large, the opening ratio of the corresponding air outlet 13 should be set small, and when the static pressure value in the air duct 12 is small, the opening ratio of the corresponding air outlet 13 should be set large. The static pressure value in the air duct 12 refers to the pressure generated during the air flow in the air duct 12, and this pressure is closely related to the air flow velocity. Specifically, at the position close to the air supply fan 11, the air flow velocity is fast, while at the position far from the air supply fan 11, the air flow velocity is slow. Correspondingly, the static pressure value in the target position of the air duct 12 close to the air supply fan 11 is less than the static pressure value in the target position far from the air supply fan 11, and the opening ratio of the air outlet 13 at the target position close to the air supply fan 11 is greater than the opening ratio of the air outlet 13 at the target position far from the air supply fan 11. In this way, with the cooperation of the static pressure value and the opening ratio, an equal air supply volume can be obtained in different regions. It can be explained that according to Bernoulli's principle, in the process of fluid flow, the total pressure = static pressure + dynamic pressure. At the position close to the air supply fan 11, the air flow velocity is fast, the dynamic pressure is high, so the static pressure is relatively low. While at the position far from the air supply fan 11, the air flow velocity slows down, the dynamic pressure decreases, and the static pressure is relatively high.

[0040] In some alternative embodiments, the static pressure value is directly proportional to the air volume of the air supply fan 11. This means that when the air volume of the air supply fan 11 is large, the corresponding static pressure value is large, and the opening ratio of the air outlet 13 should be set small. When the air volume of the air supply fan 11 is small, the corresponding static pressure value is small, and the opening ratio of the air outlet 13 should be set large. Such a design, in the case of multiple air supply fans 11, by setting the air volume of the air supply fan 11 and the opening ratio of the air outlet 13, an equal air supply volume can be obtained in different regions. Therefore, in this embodiment, by the direct proportional relationship between the static pressure value and the air volume, the opening ratio of the air outlet 13 is reasonably set, and a uniform air supply distribution in the multi-air supply fan 11 system can be effectively achieved.

[0041] In some alternative embodiments, the air duct 12 module further includes a side wall 14, a top wall 15, a bottom wall 16 and an air duct partition 17. The side wall 14, the top wall 15, the bottom wall 16 and the air duct partition 17 enclose to form the air duct 12. The air outlet 13 is provided on the air duct partition 17 and arranged along the height direction of the air duct partition 17. Each air outlet 13 includes a plurality of mesh holes 131. Multiple ways can be adopted to achieve the differential design of the opening ratio of the multiple air outlets 13. For example, when the aperture diameters of the mesh holes 131 corresponding to the multiple air outlets 13 are limited to the same size, the number of the mesh holes 131 is different; or, when the number of the mesh holes 131 corresponding to the multiple air outlets 13 is the same, the aperture sizes of the mesh holes 131 are different; or, a combination of the above two ways can be adopted, and the present utility model does not limit this. It should be further noted that the mesh holes 131 are round holes, but not limited to round holes, and can also be set as square holes, strip holes or other irregularly shaped holes. No matter what shape the holes are, the opening ratio of the air outlet 13 can be changed by setting the aperture size. Therefore, there is no special requirement for the shape of the mesh holes 131 of the present utility model.

[0042] In a specific application scenario, the air supply system in the above embodiment is applied to the agricultural field, especially agricultural breeding and scientific research laboratories. Compared with other application scenarios, the agricultural field has some special requirements.

[0043] In agricultural breeding and scientific research laboratories, plants are very sensitive to temperature and humidity. Scientific breeding requires an accurate temperature and humidity environment. Therefore, the design requirements of the laboratory are very high, not only requiring high precision, but also good uniformity. Therefore, how to improve the temperature and humidity precision and uniformity of the laboratory becomes particularly important. At present, although there are mature solutions for air conditioning systems with high-precision control, the uniformity of temperature and humidity still needs to be ensured by the air flow design of the laboratory. Many laboratories in the industry are still difficult to meet the ideal uniformity requirements, resulting in poor temperature and humidity consistency.

[0044] In addition, there are usually active heat sources in agricultural breeding and scientific research laboratories, such as the respiration of plants and artificial light sources. These heat sources will cause local overheating or uneven temperature. If not controlled, the temperature difference may affect the growth state of plants or interfere with the experimental results. Therefore, the air supply system applied to the agricultural field must consider these unique requirements.

[0045] On the contrary, in other application scenarios such as cold storages or laboratories for high-precision instruments, there is usually no obvious active heat source or the heat source is small inside. In these places, the main concern is to maintain a constant low-temperature environment or stable operating conditions, and it is not necessary to precisely control the temperature and air flow distribution in each area like in agricultural breeding and scientific research laboratories.

[0046] It is worth mentioning that as the world's second-largest seed demand country, the development of China's seed industry is in an important historical opportunity period and challenge period. After 2022, the No. 1 Central Document in 2023 once again proposed: comprehensively implement major projects on biological breeding, and accelerate the cultivation of new varieties such as high-yield and high-oil soybeans, short-growing-season rapeseeds, and saline-alkali-tolerant crops. Accelerate the industrialization pace of corn and soybean biological breeding, orderly expand the scope of pilot projects, and standardize planting management.

[0047] Among them, the development of breeding technology can be divided into four main periods: primitive domestication and selection (version 1.0), conventional breeding (version 2.0), molecular breeding (version 3.0), and intelligent breeding (version 4.0). After years of development, at present, China's breeding industry is in the stage of transition from the combination of cross-breeding (version 2.0) and molecular breeding (version 3.0), and the breeding stage is also moving from the artistry in the field to the science in the laboratory.

[0048] Based on the above requirements, please refer to Appendix Figure 3 and Appendix Figure 4 , an embodiment of the present utility model provides an artificial climate chamber, which includes a cultivation chamber 20, a cultivation rack 30, a growth lamp 40, and the air supply system in any one of the above embodiments; wherein, the cultivation rack 30 is arranged inside the cultivation chamber 20 and includes a cultivation layer 31; the growth lamp 40 is arranged on the cultivation rack 30 and is arranged opposite to the cultivation layer 31; the air outlet 13 of the air supply system faces the cultivation rack 30 to lead the heat generated by the growth lamp 40 to the outside of the cultivation chamber 20. Among them, the shape of the artificial climate chamber can be, but is not limited to, a rectangular structure.

[0049] In this embodiment, by differentially setting the opening ratios of a plurality of air outlets 13 arranged opposite to the cultivation rack 30, it is ensured that uniform air supply amounts can be obtained in each area, so that the temperature and air circulation can be effectively balanced. This not only helps to optimize the growth environment of plants and improve the success rate of agricultural breeding, but also ensures that the results of scientific research experiments are more reliable and repeatable.

[0050] In some optional embodiments, the number of the culture racks 30 is multiple, and each culture rack 30 is provided with multiple culture layers 31, and corresponds to an independently arranged air supply module 10. It should be noted that the number of the culture racks 30 depends on the size of the internal space of the culture chamber 20. In a specific embodiment, one culture chamber 20 is equipped with eight culture racks 30, and the eight culture racks 30 are arranged in an array of two columns and four rows inside the culture chamber 20, requiring eight independent air supply modules 10. In other embodiments, the culture racks 30 can also be set to one, two or other numbers, and the arrangement can also be determined according to the shape of the internal space of the culture chamber 20. The number of culture layers 31 on each culture rack 30 is set to multiple, and the specific number depends on factors such as the height of the culture rack 30. In a specific embodiment, the number of culture layers 31 on each culture rack 30 is three layers, and the three culture layers 31 are evenly arranged on the culture rack 30. A growth lamp 40 is arranged on the top of each culture layer 31, and the growth lamp 40 simulates sunlight to promote plant growth. Each culture rack 30 is equipped with an independent air supply module 10, and the air supply volume of each air supply module 10 is the same, so that each layer of the culture rack 30 at different heights can obtain cold air evenly. When the cold air passes through the growth lamp 40, it takes away the heat generated by it, thereby achieving a uniform cooling and heat dissipation effect.

[0051] In a specific embodiment, a culture chamber 20 is equipped with six culture racks 30, and the six culture racks 30 are arranged in an array of two columns and three rows inside the culture chamber 20, requiring six independent air supply modules 10, and the number of culture layers 31 on each culture rack 30 is two layers, and a growth lamp 40 is installed on the top of each culture layer 31, and the heating power of each growth lamp 40 is about 240W. Since the growth lamp 40 continuously generates heat and the heat source has 12 layers, in order to make the temperature of the three-dimensional center position of each culture layer 31 uniform, it is necessary to dissipate heat from the heat source (growth lamp 40) and the heat absorber (the shelf plate forming the culture layer 31).

[0052] In some optional embodiments, the air supply module 10 is arranged in a one-to-one correspondence with the culture rack 30, and an air outlet 13 is respectively arranged at a corresponding position of each culture layer 31 on the culture rack 30. Specifically, the air outlet 13 corresponding to each culture layer 31 on the culture rack 30 has a different opening rate. The opening rate of the air outlet 13 refers to the relevant setting of the opening rate of the air outlet 13 in the above embodiment, and will not be repeated here. In this embodiment, by respectively arranging air outlets 13 with different opening rates at corresponding positions of each culture layer 31 on the culture rack 30, uniform air supply to each layer of the culture rack 30 can be achieved, ensuring that each culture layer 31 can obtain equal cold air and achieve a uniform cooling effect.

[0053] In some alternative embodiments, air outlets 13 are respectively provided at the intermediate positions between adjacent culture layers 31 on each culture rack 30. In addition, air outlets 13 are also respectively provided at corresponding positions of each culture layer 31. This design can ensure that each culture layer 31 and its spaced positions can obtain sufficient and uniform cold air, so as to achieve a more uniform cooling and heat dissipation effect. It should be noted that the opening rate design of the air outlet 13 should not only ensure that the ventilation volume of each culture layer 31 can reach a preset value to take away the heat generated by the heat source, but also ensure the static pressure value (generally between 60 - 200 pa) inside the air duct 12 of the air supply system.

[0054] The above are only the specific implementation manners of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. The protection scope of the present utility model shall be subject to the protection scope of the claims.
