Description

Technical Field

[0001] This utility model belongs to the field of reducing temperature and humidity differences between different locations inside a fermentation chamber, and relates to a device for reducing temperature differences between different locations inside a fermentation chamber. Background Technology

[0002] Fermentation chambers are facilities for the cultivation of microorganisms and serve as laboratories that combine teaching and research. They are primarily used for undergraduate professional experiments, practical training experiments, innovative experiments, graduate professional experiments, research by laboratory teachers, and social services. Furthermore, fermentation chambers are also used in fermentation processes in the food, alcohol, pharmaceutical, and biomass industries. The most crucial aspect of using a fermentation chamber is controlling the required temperature and humidity to maintain an optimal fermentation environment. Currently, the temperature and humidity inside fermentation chambers are regulated by air conditioning. Air conditioning, or air conditioners, refers to devices that artificially regulate and control parameters such as temperature, humidity, cleanliness, and airflow within a building or structure. Most air conditioners utilize refrigerants, which evaporate or condense, thereby causing the surrounding air to evaporate or condense, thus altering the temperature and humidity.

[0003] However, existing air conditioners, whether wall-mounted, floor-standing, or central, have fixed and uniformly positioned air outlets. This causes rapid temperature changes at the location directly opposite the outlet, while other areas require slow adjustment through air circulation. If the outlet delivering cold air is at a low position, the cold air cannot be delivered to higher positions; conversely, if the outlet delivering hot air is at a high position, the hot air cannot be delivered to lower positions. This results in significant temperature differences between different areas within the fermentation chamber, including areas far from the outlet and those directly opposite it. Furthermore, the air supplied by the air conditioner carries moisture and is used to regulate humidity within the fermentation chamber, leading to significant humidity differences. These conditions cause uneven fermentation and may even result in fermentation failure. Therefore, to address these technical problems, the technical solution described in this application was developed. Utility Model Content

[0004] The purpose of this invention is to provide a device for reducing the temperature difference at various locations inside a fermentation chamber, thereby solving the aforementioned technical problems.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A device for reducing temperature differences at various locations inside a fermentation chamber includes a horizontally arranged fermentation chamber with several layers of fermentation racks placed inside. A ventilation duct is connected to the top of the fermentation chamber, and the duct is internally connected to a main air supply duct and a main air return duct. Several vertically arranged secondary air supply ducts are connected to one side of the fermentation chamber's inner wall, arranged sequentially along the length of the fermentation chamber. The upper ends of the secondary air supply ducts are connected to the main air supply ducts, and the lower ends of the secondary air supply ducts are closed. Several sets of air outlets are arranged on the outer wall of each secondary air supply duct, arranged sequentially from top to bottom along the secondary air supply duct and all facing the location of the fermentation racks. The air outlets in the same group are aligned along the same secondary air supply duct. The positions at the height are set sequentially. Several vertical secondary return air ducts are connected to the other side of the fermentation chamber wall. Several secondary return air ducts are also set sequentially along the length of the fermentation chamber. The upper ends of the secondary return air ducts are connected to the main return air ducts, and the lower ends of the secondary return air ducts are also closed. Several sets of return air inlets are set on the outer wall of each secondary return air duct. Several sets of return air inlets are set sequentially from top to bottom along the secondary return air ducts and all face the position of the fermentation rack. Several return air inlets in the same group are set sequentially at the same height along the secondary return air ducts. Each set of air outlets and return air inlets is equipped with an adjustment component to adjust the size of the air outlet and return air inlet. The adjustment component is movably connected to one of the air outlets and return air inlets.

[0007] The working principle of this invention is as follows: A main air supply pipe and a main return air pipe are installed inside the ventilation pipe above the fermentation chamber. The main air supply pipe is used to transport the air with temperature and humidity generated by the air conditioner to several secondary air supply pipes. The advantage of this arrangement is that there are several air outlets inside the fermentation chamber, avoiding the problem of large temperature differences at different locations caused by a single air outlet in the existing system. Furthermore, several sets of air outlets are set on several secondary air supply pipes. The purpose of this arrangement is to reduce the temperature difference at different heights inside the fermentation chamber. Furthermore, the air outlets in the same group are arranged sequentially at the same height along the secondary air supply pipes. This further makes the output gas more evenly distributed. With numerous secondary air outlets facing various positions of the fermentation rack, the temperature difference between different positions inside the fermentation chamber is even smaller.

[0008] Simultaneously, several secondary return air ducts are installed inside the fermentation chamber. These ducts transport air from the fermentation chamber to the main return air duct, which then returns it to the air conditioning system. This allows for adjustments based on the actual temperature and humidity of the fermentation chamber. In summer, when the air temperature in the fermentation chamber is relatively low, the return air ducts send this air back to the air conditioning unit, where it is mixed with a small amount of fresh air to create cool air before being reintroduced into the fermentation chamber. This satisfies the cooling needs of the fermentation chamber while effectively saving energy. In winter, the air can be heated and humidified to maintain a suitable temperature and humidity in the fermentation chamber. Further preferably, several sets of return air inlets are installed on each secondary return air duct, with inlets in the same set arranged sequentially at the same height along the secondary return air duct. This arrangement facilitates efficient and uniform return air treatment throughout the fermentation chamber, further reducing temperature differences within the chamber.

[0009] Furthermore, several secondary return air ducts and several secondary supply air ducts are arranged opposite each other and in an alternating manner.

[0010] Furthermore: the adjustment component includes an adjustment column, the outer wall of which is interference-fitted with the air outlet or return air outlet, the front end of which passes through one of the air outlets or return air outlets and is connected to a baffle, the baffle being located inside the secondary air supply duct or secondary return air duct, and the size and shape of the baffle matching the size and shape of the inner wall of the secondary air supply duct or secondary return air duct.

[0011] Furthermore: the rear end of the adjusting column is provided with an adjusting handle, the inner wall of the adjusting handle is provided with internal threads, the outer wall of the rear end of the adjusting column is provided with external threads, and the adjusting handle and the adjusting column are connected by threads.

[0012] Furthermore: a first constant air volume valve is provided at the connection between the secondary air supply pipe and the main air supply pipe. The upper end of the first constant air volume valve is connected to the main air supply pipe, and the lower end of the first constant air volume valve is connected to the secondary air supply pipe.

[0013] Furthermore: a second constant air volume valve is installed at the connection between the secondary return air duct and the main return air duct. The upper end of the second constant air volume valve is connected to the main return air duct, and the lower end of the second constant air volume valve is connected to the secondary return air duct.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0015] 1. A device for reducing the temperature difference between different locations inside a fermentation chamber, wherein several sets of air outlets are provided on several secondary air supply pipes and several sets of return air inlets are provided on several secondary return air pipes. By combining these, the temperature difference between different locations inside the fermentation chamber is reduced, thereby making it easier to maintain the required temperature and humidity inside the fermentation chamber.

[0016] 2. In this utility model, several secondary air supply pipes are paired with several first constant air volume valves, and several secondary return air pipes are paired with several second constant air volume valves, so that the temperature and humidity inside the fermentation chamber are more similar.

[0024] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0025] Example 1

[0026] This utility model relates to a device for reducing temperature differences at various locations inside a fermentation chamber, such as... Figure 1 , Figure 2 , Figure 3 As shown, the system includes a horizontally arranged fermentation chamber 1, inside which several layers of fermentation racks 2 are placed. A ventilation duct 3 is connected to the top of the fermentation chamber 1, and the ventilation duct 3 is connected to a main air supply duct 4 and a main return air duct 5. Several vertically arranged secondary air supply ducts 6 are connected to one side of the inner wall of the fermentation chamber 1. These secondary air supply ducts 6 are arranged sequentially along the length of the fermentation chamber 1, with their upper ends connected to the main air supply duct 4 and their lower ends closed. Several sets of air outlets 7 are arranged on the outer wall of each secondary air supply duct 6, arranged sequentially from top to bottom along the secondary air supply duct 6 and all facing the location of the fermentation racks 2. The air outlets 7 in the same group are located at the same height along the secondary air supply duct 6. The fermentation chamber 1 is arranged in sequence. On the other side of the inner wall of the fermentation chamber 1, there are several vertically arranged secondary return air pipes 8. The secondary return air pipes 8 are also arranged in sequence along the length of the fermentation chamber 1. The upper ends of the secondary return air pipes 8 are connected to the main return air pipes 5 respectively. The lower ends of the secondary return air pipes 8 are also closed. Several sets of return air inlets 9 are arranged on the outer wall of each secondary return air pipe 8. The sets of return air inlets 9 are arranged in sequence from top to bottom along the secondary return air pipes 8 and all face the location of the fermentation rack 2. The sets of return air inlets 9 are arranged in sequence at the same height along the secondary return air pipes 8. Each set of air outlets 7 and return air inlets 9 is equipped with an adjustment component to adjust the size of the air outlets 7 and 9. The adjustment component is movably connected to one of the air outlets 7 and 9.

[0027] The specific implementation method of this embodiment is as follows: a main air supply pipe and a main return air pipe are set inside the ventilation pipe above the fermentation chamber. The main air supply pipe is used to transport the air with temperature and humidity generated by the air conditioner to several secondary air supply pipes. The advantage of this setting is that there are several air outlets inside the fermentation chamber, avoiding the problem of large temperature differences at different positions caused by the single air outlet in the existing system. At the same time, several sets of air outlets are set on several secondary air supply pipes. The purpose of this setting is to reduce the temperature difference at different heights inside the fermentation chamber. Furthermore, the air outlets in the same group are set sequentially at the same height along the secondary air supply pipes. This further makes the output gas more evenly distributed. This means that there are numerous secondary air outlets facing various positions of the fermentation rack, which makes the temperature difference between various positions inside the fermentation chamber even smaller.

[0028] Simultaneously, several secondary return air ducts are installed inside the fermentation chamber. These ducts transport air from the fermentation chamber to the main return air duct, which then returns it to the air conditioning system. This allows for adjustments based on the actual temperature and humidity of the fermentation chamber. In summer, when the air temperature in the fermentation chamber is relatively low, the return air ducts send this air back to the air conditioning unit, where it is mixed with a small amount of fresh air to create cool air before being reintroduced into the fermentation chamber. This satisfies the cooling needs of the fermentation chamber while effectively saving energy. In winter, the air can be heated and humidified to maintain a suitable temperature and humidity in the fermentation chamber. Further preferably, several sets of return air inlets are installed on each secondary return air duct, with inlets in the same set arranged sequentially at the same height along the secondary return air duct. This arrangement facilitates efficient and uniform return air treatment throughout the fermentation chamber, further reducing temperature differences within the chamber.

[0029] By adjusting the components, the air outlets at different heights of each air supply duct have different actual air outlet diameters. This design ensures that the air volume at different heights of the fermentation chamber is approximately the same. At the same time, the adjustment components on the secondary return air ducts allow for the adjustment of the actual diameter of the return air outlets at different heights on each secondary return air duct. This design ensures that the return air volume at different heights of the fermentation chamber is approximately the same, thereby further reducing the temperature difference inside the fermentation chamber.

[0030] Example 2

[0031] This utility model relates to a device for reducing temperature differences at various locations inside a fermentation chamber, such as... Figure 1 , Figure 2 , Figure 3 As shown, several secondary return air ducts 8 and several secondary supply air ducts 6 are arranged opposite each other and staggered.

[0032] The adjustment assembly includes an adjustment column 10. The outer wall of the adjustment column 10 is interference-fitted with the air outlet 7 or the return air outlet 9. The front end of the adjustment column 10 passes through one of the air outlets 7 or the return air outlet 9 and is connected to a baffle 11. The baffle 11 is located inside the secondary air supply duct 6 or the secondary return air duct 8. The size and shape of the baffle 11 match the size and shape of the inner wall of the secondary air supply duct 6 or the secondary return air duct 8.

[0033] The rear end of the adjusting column 10 is provided with an adjusting handle 12. The inner wall of the adjusting handle 12 is provided with an internal thread, and the outer wall of the rear end of the adjusting column 10 is provided with an external thread. The adjusting handle 12 and the adjusting column 10 are connected by threads.

[0034] The specific implementation method of this embodiment is as follows: several secondary return air pipes and several secondary supply air pipes are arranged directly facing each other so that they all face the fermentation rack, making the temperature and humidity difference around the fermentation rack smaller, and the staggered arrangement makes the temperature and humidity inside the entire fermentation chamber more uniform.

[0035] The adjustment column is designed to pass through an air outlet or return air outlet and be interference-fitted with it. This design requires an operator to make adjustments, thus preventing the adjustment column from sliding along the air outlet or return air outlet. The baffle connected to the front end of the adjustment column facilitates the adjustment of the size of the air outlet or return air outlet.

[0036] The adjustment handle facilitates the movement of the adjustment column by the operator. The adjustment handle is threadedly connected to the adjustment column, which facilitates further securing the connection between the adjustment column and the air outlet or return air outlet. When it is necessary to move the position of the adjustment column, the adjustment handle is loosened to facilitate the movement of the adjustment column. After the movement is completed, the adjustment handle is tightened to secure the adjustment column.

[0037] Example 3

[0038] This utility model relates to a device for reducing temperature differences at various locations inside a fermentation chamber, such as... Figure 1 , Figure 2 , Figure 3 As shown, a first constant air volume valve 13 is provided at the connection between the secondary air supply pipe 6 and the main air supply pipe 4. The upper end of the first constant air volume valve 13 is connected to the main air supply pipe 4, and the lower end of the first constant air volume valve 13 is connected to the secondary air supply pipe 6.

[0039] A second constant air volume valve 14 is provided at the connection between the secondary return air duct 8 and the main return air duct 5. The upper end of the second constant air volume valve 14 is connected to the main return air duct 5, and the lower end of the second constant air volume valve 14 is connected to the secondary return air duct 8.

[0040] The specific implementation method of this embodiment is as follows: each secondary air supply pipe is equipped with a first constant air volume valve at the connection between the secondary air supply pipe and the main return air pipe. The first constant air volume valve makes the air force delivered by the air conditioner evenly distributed to the interior of each secondary air supply pipe. The advantage of this setting is that the air carrying humidity and temperature is further evenly blown to various positions inside the fermentation.

[0041] Each secondary return air duct is equipped with a second constant air volume valve at its connection with the main return air duct. The second constant air volume valve ensures that each secondary return air duct absorbs approximately the same amount of air. The advantage of this design is that the amount of air recovered from various locations inside the fermentation chamber is approximately the same, which further reduces the temperature and humidity differences inside the fermentation chamber.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model. The present utility model is also applicable to other cabins or rooms that require uniform adjustment. Any modifications, equivalent substitutions and improvements made by those skilled in the art within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
