Description

Technical Field

[0001] This disclosure relates to the field of air handling unit technology, and more particularly to a filtered air outlet device and an air handling unit. Background Technology

[0002] In air handling units with modular cabinets and similar structures, due to the high demand for heating, these units often use high-power heating devices to process the supply air. In such units, if the air outlet is a fixed outlet, uneven distribution of the heating elements can lead to lower heating efficiency in some areas compared to others. Furthermore, unevenly distributed heating elements can cause uneven airflow distribution, increasing airflow resistance in certain areas and affecting the overall uniformity of airflow, thus reducing heating efficiency. Ultimately, this results in uneven temperature distribution in the exhaust air, creating localized high-temperature or low-temperature zones. Some units are equipped with dynamic outlets, but the adjustment of these outlets relies on a single temperature feedback mechanism, which cannot accurately detect temperature differences at the terminal (such as near the filter); this still results in uneven exhaust air temperature at the outlet. Utility Model Content

[0003] In view of this, in order to solve the technical problem of uneven exhaust temperature in the prior art, this disclosure provides a filtered exhaust device and an air handling unit.

The filter assembly includes a filter and multiple temperature detection devices, which are distributed on the filter. The air guide assembly includes multiple air guide blade groups to form multiple sub-air guide zones. In the air filtration device, each sub-air guide zone is equipped with at least one temperature detection device for detecting the air outlet temperature of the filter corresponding to the corresponding sub-air guide zone. The temperature detection device and the drive component of the air guide blade assembly are electrically connected to the control device. The control device is configured to control the air guiding direction of the multiple air guide blade assemblies in the air guide assembly based on the temperatures detected by the multiple temperature detection devices, so as to balance the outlet air temperature at different positions of the filter outlet device.

[0005] In one alternative implementation, The filter includes a filter section body and a support. The filter section body is mounted on the support, which is located on the side of the filter section facing the air guide assembly. Multiple temperature detection devices are arranged around the support.

[0006] In one alternative implementation, The filter includes a filter screen, and a plurality of the temperature detection devices constitute a flexible thin-film temperature sensor array, which is disposed within the pleats and grooves of the filter screen.

[0008] In one alternative implementation, The air guiding assembly includes an upper sub-air guiding area, a lower sub-air guiding area, a left sub-air guiding area, and a right sub-air guiding area. The upper and lower sub-air guiding areas are arranged vertically, and the left and right sub-air guiding areas are arranged horizontally. The left sub-air guiding area is located to the left of the upper and lower sub-air guiding areas, and the right sub-air guiding area is located to the right of the upper and lower sub-air guiding areas, thus forming a square air guiding area.

[0009] In one alternative implementation, The air guiding assembly includes a triangular upper sub-air guiding area, a lower sub-air guiding area, a left sub-air guiding area, and a right sub-air guiding area, with the apex corners of the upper sub-air guiding area, the lower sub-air guiding area, the left sub-air guiding area, and the right sub-air guiding area coinciding to form a square air guiding area.

[0012] According to a second aspect of the present disclosure, an air handling unit is provided, the air handling unit including a heating device and a filter outlet device as described in any of the first aspects, wherein the filter outlet device is disposed downstream of the heating device in the air outlet direction of the air handling unit.

[0013] In one alternative implementation, The air handling unit includes an air conditioner.

[0014] The technical solutions provided by the embodiments of this disclosure can include the following beneficial effects: In this disclosure, multiple temperature detection devices distributed on the filter of the air outlet device can capture the outlet air temperature in different areas in real time (such as the filter position temperature corresponding to each sub-air guide zone), forming multi-point temperature monitoring. Compared with traditional single temperature feedback, this design can accurately identify local high-temperature or low-temperature areas of the outlet air, providing a comprehensive and accurate data analysis basis for subsequent adjustment, and solving the problem of adjustment lag caused by inaccurate temperature sensing from the source. In addition, the air guide assembly is divided into multiple sub-air guide zones, each zone is equipped with an independent air guide blade group and a corresponding temperature detection device, which can establish a one-to-one correspondence between "temperature detection and airflow adjustment". The control device can adjust the airflow direction of the corresponding air guide vane group according to the real-time temperature difference of each sub-air guide zone. By dynamically regulating the local airflow, it balances the outlet air temperature of different areas, effectively eliminating local temperature differences and improving the overall airflow uniformity. The uniform outlet air temperature avoids local overheating or undercooling, improving the user comfort of the air handling unit equipped with this filtration outlet device. In addition, dynamic adjustment can also reduce ineffective energy consumption to a certain extent (such as avoiding excessive heating of the overall airflow to balance local low temperatures), indirectly improving the energy utilization efficiency of the air handling unit and achieving dual optimization of performance and energy saving. This disclosure fundamentally solves the problem of uneven outlet air temperature in traditional units through the synergistic effect of "precise sensing-zone adjustment," providing a reliable guarantee for the efficient and stable operation of the air handling unit and further enhancing the user experience.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments.

[0030] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application.

It should be understood that the preferred embodiments are only for illustrating this application and are not intended to limit the scope of protection of this application.

[0032] To address the technical problem of uneven exhaust temperature in the prior art, this disclosure provides a filtered exhaust device and an air handling unit.

[0033] In this disclosure, multiple temperature sensing devices are distributed on the filter of the air outlet device, which can capture the outlet air temperature in different areas in real time (such as the filter position temperature corresponding to each sub-air guide zone), forming multi-point temperature monitoring. Compared with traditional single temperature feedback, this design can accurately identify local high-temperature or low-temperature areas in the outlet air, providing a comprehensive and accurate data analysis basis for subsequent adjustment, and solving the problem of adjustment lag caused by inaccurate temperature sensing from the source. In addition, the air guide assembly is divided into multiple sub-air guide zones, each equipped with an independent air guide blade group and a corresponding temperature sensing device, which can establish a one-to-one correspondence between "temperature detection and airflow adjustment". The control device can adjust the airflow direction of the corresponding air guide vane group according to the real-time temperature difference of each sub-air guide zone. By dynamically regulating the local airflow, it balances the outlet air temperature of different areas, effectively eliminating local temperature differences and improving the overall airflow uniformity. The uniform outlet air temperature avoids local overheating or undercooling, improving the user comfort of the air handling unit equipped with this filtration outlet device. In addition, dynamic adjustment can also reduce ineffective energy consumption to a certain extent (such as avoiding excessive heating of the overall airflow to balance local low temperatures), indirectly improving the energy utilization efficiency of the air handling unit and achieving dual optimization of performance and energy saving. This disclosure fundamentally solves the problem of uneven outlet air temperature in traditional units through the synergistic effect of "precise sensing-zone adjustment," providing a reliable guarantee for the efficient and stable operation of the air handling unit and further enhancing the user experience.

[0034] In one exemplary embodiment, reference Figures 1 to 3 As shown, a filtered air outlet device and an air handling unit equipped with the filtered air outlet device are provided. The air handling unit may be, for example, an air conditioner, an air purifier, or a humidifier with a heating function. In this embodiment, the filtered air outlet device is disposed in the air handling unit, and in the air outlet direction of the air handling unit, the filtered air outlet device is disposed downstream of the heating device of the air handling unit, the heating device may be, for example, an electric heater.

[0035] The air filtration device includes a filter assembly 1, an air guide assembly 2, and a control device (not shown in the figure). The filter assembly 1 includes a filter 11 and multiple temperature detection devices 12, which are distributed on the filter 11 to detect the gas temperature at different locations. This allows for the detection of real-time temperature information at different locations at the air outlet of the air filtration device. This multi-point, distributed temperature detection method overcomes the limitations of traditional single temperature feedback, accurately sensing temperature differences in different areas of the air outlet. This provides an accurate data basis for subsequent fine-tuning, effectively solving the problem of uneven temperature caused by the inability to accurately sense temperature differences at the end.

[0036] The air guide assembly 2 includes multiple air guide blade groups to form multiple sub-air guide zones. In the filter outlet device, each sub-air guide zone is equipped with at least one temperature detection device 12 for detecting the outlet air temperature of the filter 11 corresponding to the respective sub-air guide zone.

[0037] For example, the air guide assembly 2 may include four air guide blade groups to form four sub-air guide zones, respectively denoted as the first sub-air guide zone, the second sub-air guide zone, the third sub-air guide zone, and the fourth sub-air guide zone. The filter assembly 1 may include four temperature detection devices 12 (e.g., temperature sensors), each corresponding to one of the four sub-air guide zones; that is, the four temperature detection devices 12 correspond to the four air guide blade groups. The four temperature detection devices 12 are respectively denoted as the first temperature detection device 12, the second temperature detection device 12, the third temperature detection device 12, and the fourth temperature detection device 12. Specifically, the first temperature detection device 12 corresponds to the first sub-air guide zone and is used to detect the outlet air temperature of the filter 11 corresponding to the first sub-air guide zone; the second temperature detection device 12 corresponds to the second sub-air guide zone and is used to detect the temperature of the filter 11 corresponding to the second sub-air guide zone; the third temperature detection device 12 corresponds to the third sub-air guide zone and is used to detect the temperature of the filter 11 corresponding to the third sub-air guide zone; and the fourth temperature detection device 12 corresponds to the fourth sub-air guide zone and is used to detect the temperature of the filter 11 corresponding to the fourth sub-air guide zone.

[0038] The temperature detection device 12 and the drive component (e.g., a drive motor) of the air guide vane assembly are electrically connected to the control device. That is, each temperature detection device 12 is electrically connected to the control device, and each drive component of the air guide vane assembly is electrically connected to the control device. The control device is configured to control the air guiding direction of multiple air guide vane assemblies in the air guide assembly 2 based on the temperatures detected by the multiple temperature detection devices 12, so as to balance the outlet air temperature at different locations of the air outlet device.

[0039] The filter assembly 1 is responsible for filtering the exhaust gas to ensure the cleanliness of the outlet air. The air guide assembly 2 can adjust the airflow direction, thereby balancing the outlet air temperature at different locations of the filter assembly. The control device can acquire the temperature information detected by the temperature detection device 12 and issue control commands to each driving component based on the temperature information to coordinate the operation of the filter assembly 1 and the air guide assembly 2 to achieve the goal of temperature balance.

[0040] In this embodiment, the arrangement of multiple guide vane groups divides the air outlet into multiple independently adjustable sub-guide zones, providing a structural basis for local airflow control. Furthermore, each sub-guide zone is equipped with at least one temperature detection device 12 to detect the corresponding outlet air temperature. This one-to-one correspondence establishes a direct link between local temperature sensing and local airflow adjustment, enabling the control device to specifically adjust the airflow in a particular sub-guide zone based on its temperature conditions, thereby achieving precise local temperature control.

[0041] Moreover, the control device no longer relies on a single temperature feedback, but comprehensively analyzes the spatial temperature distribution data provided by multiple temperature detection devices 12. Based on this multi-point temperature data, the control device can intelligently determine the temperature of different areas and adjust the airflow direction of each air guide blade group in the air guide assembly 2 accordingly. For example, if the outlet air temperature of the first sub-air guide zone is lower than that of the second sub-air guide zone, the control device can determine the increase in the airflow degree of the first sub-air guide zone (i.e., the opening degree of the air guide blade 200) compared to the airflow degree of the second sub-air guide zone according to the size of the temperature difference, thereby reducing the outlet air temperature difference between the first and second sub-air guide zones to a set threshold, thus ensuring the uniformity of the outlet air temperature.

[0042] This embodiment effectively solves the problem of uneven exhaust temperature at the air handling unit's outlet by precisely sensing the temperature in different areas at the air outlet and dynamically adjusting the airflow direction in the corresponding areas based on this sensing data. This improves the uniformity of the exhaust air from the filter outlet device and the air handling unit equipped with it. Furthermore, dynamic adjustment can reduce ineffective energy consumption to some extent (e.g., avoiding excessive heating of the overall airflow to balance localized low temperatures), indirectly improving the energy efficiency of the air handling unit and achieving dual optimization of performance and energy saving. In short, this embodiment fundamentally solves the problem of uneven exhaust temperature in traditional units through the synergistic effect of "precise sensing and zoned adjustment," providing a reliable guarantee for the efficient and stable operation of the air handling unit and further enhancing the user experience.

[0043] In one exemplary embodiment, reference Figure 1 As shown, a filtration air outlet device and an air handling unit equipped with the filtration air outlet device are provided. The air handling unit can be, for example, an air conditioner, an air purifier, or a humidifier with a heating function. In this embodiment, the filter 11 of the filtration air outlet device includes a filter section body 111 and a bracket 112. The filter section body 111 is mounted on the bracket 112 to ensure that the filter section body 111 can be firmly fixed by the bracket 112, thereby maintaining stability when airflow passes through, avoiding shaking or deformation, and ensuring the filtration effect.

[0044] The bracket 112 is located on the side of the filter section facing the air guide assembly 2, and multiple temperature detection devices 12 are arranged around the bracket 112. The bracket 112 and the temperature detection devices 12 installed on it are positioned on the downstream side of the filter section, that is, in the area before the air enters the air guide assembly 2 after being filtered. This allows the temperature detection devices 12 to detect the temperature of the filtered air, avoiding interference from unfiltered air or the operation of the air guide assembly 2, thereby obtaining more accurate and representative outlet air temperature data.

[0045] Furthermore, in this embodiment, the temperature detection device 12 is mounted on the bracket 112. Compared to placing it directly on the filter material, this provides a more robust and protected installation environment for the temperature detection device 12, reducing the risk of damage caused by airflow impact, dust accumulation, or physical contact. Simultaneously, this distributed arrangement around the bracket 112 allows the temperature detection device 12 to more comprehensively cover the cross-section of the filtered airflow, better detect the temperature in different areas, and provide the control device with more refined temperature distribution information, thereby achieving more precise local temperature regulation and overall balanced airflow temperature.

[0046] This embodiment, through the structural composition of the filter 11 and the installation position of the temperature detection device 12, can improve the accuracy, reliability, and overall stability of temperature detection, thereby better supporting the balanced control of the outlet air temperature.

[0047] In one exemplary embodiment, reference Figure 1 and Figure 4 As shown, a filtration air outlet device and an air handling unit equipped with the filtration air outlet device are provided. The air handling unit can be, for example, an air conditioner, purifier, or humidifier with heating function. In this embodiment, the filter 11 includes a filter screen 100, which may include pleats and grooves to increase the filtration area. Multiple temperature detection devices 12 can constitute a flexible thin-film temperature sensor array; that is, the temperature detection device 12 in this embodiment can be a flexible thin-film temperature sensor, and then a flexible thin-film temperature sensor array forms multiple temperature detection devices 12.

[0048] Among them, the flexible thin-film temperature sensor, compared with the traditional rigid sensor, has the characteristics of being flexible and thin, which allows it to better adapt to the complex shape of the filter 100. This enables the flexible thin-film temperature sensor array to be placed within the folds and grooves of the filter 100, thereby achieving a tighter fit. Furthermore, the array arrangement indicates that the sensors are multiple and regularly arranged, enabling dense and comprehensive temperature detection of different areas of the filter 100, significantly improving the accuracy and coverage of temperature detection.

[0049] Furthermore, placing the flexible thin-film sensor array within the pleats and grooves of the filter 100 fully utilizes the inherent structure of the filter 100, allowing the sensor to be tightly embedded within its internal space. This results in a temperature closer to the actual passing airflow, leading to more accurate temperature detection. Simultaneously, this embedded mounting method effectively prevents the sensor from protruding from the filter 100 surface, reducing airflow obstruction and resistance, ensuring uniform airflow without affecting the normal filtration function of the filter 11. Additionally, placing the sensor within the grooves provides physical protection, making it less susceptible to external mechanical damage, thereby improving the sensor's reliability and lifespan.

[0050] In this embodiment, a flexible thin-film temperature sensor array is used and cleverly placed in the pleats and grooves of the filter screen 100. This effectively solves the problem of accurately, tightly and without affecting airflow in arranging the temperature detection device 12 on the complex filter screen 100 structure, significantly improving the accuracy and reliability of temperature detection, providing more accurate temperature feedback for the control device, thereby better realizing the fine control of the air guide component 2, and ultimately achieving the goal of balancing the air outlet temperature at different positions of the filter air outlet device.

[0051] In one exemplary embodiment, reference Figure 1 and Figure 5 As shown, a filtration air outlet device and an air handling unit equipped with the filtration air outlet device are provided. The air handling unit can be, for example, an air conditioner, a purifier, or a humidifier with a heating function. In this embodiment, the filter 11 includes multiple layers of filter screens 100, which can improve filtration efficiency and dust holding capacity, and also provide ideal space for the arrangement of the temperature detection device 12.

[0052] In this multi-layer filter 100, multiple temperature sensing devices 12 are embedded within the filter media, rather than merely adhering to its surface. This interlayer arrangement allows the temperature sensing devices 12 to more deeply sense temperature changes as airflow passes through different filter layers, thus obtaining more accurate and detailed internal temperature information of the filter 11. Furthermore, by placing the temperature sensing devices 12 between the filter layers, they are physically protected by the filter 100, reducing the risk of damage during airflow impact or routine maintenance, and improving the reliability and lifespan of the filtration system. Simultaneously, the concealment of the temperature sensing devices 12 within the filter layers reduces direct obstruction of the airflow channel, helping to maintain airflow uniformity and preventing the introduction of additional localized airflow resistance due to their arrangement.

[0053] The arrangement of the temperature detection device 12 in this embodiment allows the control device to perform more precise control on the air guide assembly 2 based on more comprehensive and accurate temperature information, thereby more effectively balancing the air outlet temperature at different locations of the filter air outlet device and improving the overall performance and comfort of the air handling unit.

[0054] In one exemplary embodiment, reference Figure 1 and Figure 2 As shown, a filtration air outlet device and an air handling unit equipped with the filtration air outlet device are provided. The air handling unit can be, for example, an air conditioner, a purifier, or a humidifier with a heating function. In this embodiment, the air guiding area of ​​the air guiding assembly 2 may include four sub-air guiding areas: an upper sub-air guiding area 10, a lower sub-air guiding area 20, a left sub-air guiding area 30, and a right sub-air guiding area 40. The upper sub-air guiding area 10 and the lower sub-air guiding area 20 are arranged vertically, and the left sub-air guiding area 30 and the right sub-air guiding area 40 are arranged horizontally. The left sub-air guiding area 30 is located to the left of the upper sub-air guiding area 10 and the lower sub-air guiding area 20, and the right sub-air guiding area 40 is located to the right of the upper sub-air guiding area 10 and the lower sub-air guiding area 20, so as to form a square air guiding area.

[0055] For example, the upper sub-guide zone 10 and the lower sub-guide zone 20 are arranged vertically and located in the middle area of ​​the guide zone. The left sub-guide zone 30 is located to the left of the middle area, and the right sub-guide zone 40 is located to the right of the middle area, thus forming a square guide zone.

[0056] In this embodiment, a square air guide area is formed by the coordinated arrangement of the above-mentioned upper, lower, left, and right sub-air guide zones. This square overall layout can not only efficiently cover common square or rectangular air outlets, ensuring that the temperature of the entire air outlet area can be effectively monitored and controlled, but its regularity also simplifies the design and manufacturing of the air guide component 2 and the arrangement of the temperature detection device 12.

[0057] In addition, the clear division of the four sub-air guide zones in this embodiment systematically divides the entire air outlet area into independently controllable air guide blade groups. This provides a clearer and more defined detection area for multiple temperature detection devices 12, and provides a clear execution boundary for the control device to control the air guide direction of the corresponding air guide blade group based on the detected temperature. This avoids the problem of control blind spots or low efficiency caused by ambiguous area division, so as to achieve more comprehensive and accurate balanced control of the air outlet temperature.

[0058] In one exemplary embodiment, reference Figure 1 and Figure 3As shown, a filtration air outlet device and an air handling unit equipped with the filtration air outlet device are provided. The air handling unit can be, for example, an air conditioner, a purifier, or a humidifier with a heating function. In this embodiment, the air guiding area of ​​the air guiding assembly 2 includes a triangular upper sub-air guiding area 10, a lower sub-air guiding area 20, a left sub-air guiding area 30, and a right sub-air guiding area 40, and the apex corners of the upper sub-air guiding area 10, the lower sub-air guiding area 20, the left sub-air guiding area 30, and the right sub-air guiding area 40 coincide to form a square air guiding area.

[0059] In this embodiment, the air guiding assembly 2 is divided into a triangular upper sub-air guiding zone 10, a lower sub-air guiding zone 20, a left sub-air guiding zone 30, and a right sub-air guiding zone 40, instead of the traditional square shape. This allows each sub-air guiding zone to more flexibly adjust the direction of its internal airflow. The triangular shape allows airflow to radiate outward or converge inward from a point (i.e., the apex), thus providing a basis for fine-grained airflow control. This division method can better adapt to non-uniform temperature distribution caused by uneven arrangement of heating devices or differences in airflow resistance, especially when the temperature unevenness exhibits central radial or localized characteristics, which can better improve the uniformity control of the outlet air temperature.

[0060] Furthermore, in this embodiment, by aligning the apex angles of the four triangular sub-guide zones at their center, forming a common central point, the entire guide zone can coordinate and adjust airflow around this central point. This allows the control device to more effectively handle airflow and temperature unevenness issues arising from diffusion or convergence from the center. For example, when the temperature in the central area is too high or too low, the airflow direction of the four triangular sub-guide zones surrounding this central point can be adjusted to precisely guide hot and cold airflows to or away from the central area from different directions, thereby achieving precise intervention in local temperature and rapid overall temperature equalization. This central convergence or radial adjustment capability, compared to simple parallel or vertical adjustments, can more effectively eliminate complex temperature gradients and better improve the precision of outlet air temperature adjustment.

[0061] Furthermore, in this embodiment, although triangular sub-air guide zones are used internally, the overall air guide zone remains square. This ensures good compatibility between the filter outlet device and the square air outlets or channels commonly found in air handling units, facilitating integration and installation. Simultaneously, the overall square shape guarantees effective utilization of the air outlet area, fully leveraging the refined air guiding advantages of the triangular sub-air guide zone division while maintaining practicality.

[0062] In other words, by adopting a triangular sub-air guide zone division method with overlapping apex angles, this embodiment can provide a more adaptive and precise airflow adjustment mechanism, thereby more effectively solving the problem of uneven local temperature caused by uneven heating or complex airflow distribution, and ultimately achieving a balance of air outlet temperature at different locations of the filter outlet device, improving the overall performance of the air handling unit and the user experience.

[0063] In one exemplary embodiment, reference Figure 1 , Figure 6 and Figure 7 As shown, a filtration air outlet device and an air handling unit equipped with the filtration air outlet device are provided. The air handling unit can be, for example, an air conditioner with heating function, an air purifier, or a humidifier, etc. In this embodiment, the air guide assembly 2 may include a first air guide element 21 and a second air guide element 22. By decomposing the air guide assembly 2 into two independent air guide elements, more precise airflow control can be achieved.

[0064] The first-layer air guide 21 is oriented in a first direction (e.g., horizontal), allowing the airflow to be initially guided or mixed in that direction. Meanwhile, the second-layer air guide 22 is oriented in a second direction (e.g., vertical), allowing the airflow to be further guided or mixed in that direction.

[0065] In this design, the first and second directions are perpendicular to each other. By making the airflow directions of the two layers of air guides perpendicular to each other, the air guide assembly 2 gains the ability to adjust the airflow in any direction within a two-dimensional plane. For example, the first layer can adjust the airflow distribution in the horizontal direction, and the second layer can adjust the airflow distribution in the vertical direction. When there is complex, non-unidirectional temperature unevenness at the air outlet (e.g., hot in the upper left corner and cold in the lower right corner), this two-dimensional adjustment capability can more accurately guide high-temperature airflow to low-temperature areas or low-temperature airflow to high-temperature areas, achieving a more thorough and uniform temperature mixing. This significantly improves the uniformity of the outlet air temperature and the adaptability of the filtration air outlet device.

[0066] In one exemplary embodiment, reference Figures 1 to 4As shown, a filtration air outlet device and an air handling unit equipped with the filtration air outlet device are provided. The air handling unit can be, for example, an air conditioner, purifier, or humidifier with heating function. In this embodiment, the blades in multiple guide vane groups are evenly arranged in the same manner. For example, in different sub-guide vane zones, the blades used to adjust the airflow direction have a uniform arrangement pattern and spacing. This better ensures that each sub-guide vane zone can produce a similar airflow deflection effect when receiving control commands, avoiding inconsistent airflow adjustment caused by structural differences. This provides a reliable structural basis for the control device to achieve precise regional temperature regulation, allowing the control strategy to act more effectively on the entire air outlet surface, thereby promoting the uniformity of the outlet air temperature.

[0067] Furthermore, the blades in multiple guide vane groups have the same width. This uniformity in blade width further ensures consistency in airflow resistance and equal airflow guiding capacity across different sub-guide vane zones. When all blades have the same width, the difference in resistance experienced by the airflow as it passes through different sub-guide vane zones is reduced, helping to maintain a uniform overall airflow distribution. This avoids airflow deviation caused by excessively high or low local airflow resistance, contributing to a smoother and more uniform airflow output, and thus more effectively balancing the outlet air temperature at different locations of the filtration system.

[0068] This embodiment ensures the consistency and uniformity of airflow regulation in different sub-guide zones by limiting the arrangement and width of the blades in the guide vane group, thereby improving the accuracy and efficiency of overall temperature balance.

[0069] In one exemplary embodiment, reference Figures 1 to 7 As shown, a filtration air outlet device and an air handling unit equipped with the filtration air outlet device are provided. The air handling unit can be, for example, an air conditioner, purifier, or humidifier with heating function. In this embodiment, multiple independently adjustable air guide vane groups are provided at the outlet of the filter assembly 1, and a temperature detection device 12 (e.g., a temperature sensor) is placed around each air guide vane group to detect the temperature of each area in real time. Therefore, each air guide vane group corresponds to a specific temperature zone, and its opening and closing angle is precisely controlled by a drive component (e.g., a micro servo motor). The control device calculates the standard deviation by comparing the temperature values ​​detected by each temperature sensor. When the standard deviation exceeds a preset threshold (e.g., ±1℃), the control device will automatically adjust the angle of the air guide vanes 200 to achieve temperature equalization.

[0070] In this system, the opening of the guide vanes 200 in the lower temperature zone is increased to guide more hot airflow through that zone. The angle is continuously fine-tuned until the temperature difference between the sensors approaches zero. If the temperature of the left sub-guide zone 30 is lower than that of the right sub-guide zone 40, the control device can determine the increase in the opening of the guide vane of the left sub-guide zone 30 compared to the guide vane of the right sub-guide zone 40 based on the temperature difference. Similarly, if the temperature of the upper sub-guide zone 10 is lower than that of the lower sub-guide zone 20, the control device can determine the increase in the opening of the guide vane of the upper sub-guide zone 10 compared to the guide vane of the lower sub-guide zone 20 based on the corresponding temperature difference. Likewise, if the temperature of one sub-guide zone is lower than that of another sub-guide zone, the control device can determine the increase in the opening of the guide vane of the aforementioned sub-guide zone compared to the guide vane of the other sub-guide zone based on the temperature difference. During this process, the temperature difference between the sub-guide zones gradually decreases, and consequently, the difference in the opening of the guide vanes of each sub-guide zone also gradually decreases until the temperature difference drops to a set threshold.

[0071] Specifically, in this embodiment, uniform airflow can be truly achieved through temperature difference compensation and dynamic balance mode. Taking the adjustment of the left sub-guide zone 30 and the right sub-guide zone 40 as an example, the control device reads the temperature (T_left) of the left sub-guide zone 30 and the temperature (T_right) of the right sub-guide zone 40 in real time according to the temperature sensor, and then calculates the temperature difference ΔT = T_left - T_right. If |ΔT| < preset threshold (|±1℃|), the current opening is maintained, and the process returns to the step of reading the temperature at the beginning. If |ΔT| > preset threshold (|±1℃|), when ΔT>0, it indicates that the left is hot and the right is cold, so the opening of the guide vane 200 of the left sub-guide zone 30 can be reduced, and the opening of the guide vane of the right sub-guide zone 40 can be increased simultaneously; when ΔT<0, it indicates that the left is cold and the right is hot, so the opening of the guide vane 200 of the left sub-guide zone 30 can be increased, and the opening of the guide vane 200 of the right sub-guide zone 40 can be decreased simultaneously.

[0072] This can be based on proportional-integral (PI) control, where ΔOpening = Kp * |ΔT| + Ki * ∫|ΔT| dt, Kp is the proportional coefficient (an adjustable parameter that determines the sensitivity / intensity of the adjustment), |ΔT| is the absolute value of the temperature difference, Ki is the integral coefficient (an adjustable parameter), and ∫|ΔT| dt is the integral of the absolute value of the temperature difference over time (error accumulation). If ΔT > 0 (left hot, right cold): the opening degree of the guide vanes of the new left sub-guide zone 30 is 200° = the opening degree of the guide vanes of the current left sub-guide zone 30 is 200° - ΔOpening, and the opening degree of the guide vanes of the new right sub-guide zone 40 is 200° = the opening degree of the guide vanes of the current right sub-guide zone 40 is 200° + ΔOpening. If ΔT < 0 (left is cold, right is hot), the opening degree of the guide vanes in the new left sub-guide zone 30 (200°) = the current opening degree of the guide vanes in the left sub-guide zone 30 (200°) + ΔOpening; the opening degree of the guide vanes in the new right sub-guide zone 40 (200°) = the current opening degree of the guide vanes in the right sub-guide zone 40 (200°) - ΔOpening. After waiting for one sampling cycle, return to the initial step of reading the temperature, and continue monitoring and adjustment. Through this dynamic adjustment based on temperature difference feedback, the control device can automatically correct the imbalance of airflow in the left and right areas, causing the temperatures in the two areas to gradually converge, ultimately reaching the set target temperature.

[0073] For example, in a large data center scenario, a filter assembly 1 with four integrated temperature sensors is installed. Initially, the temperature of the left sub-air guide zone 30 is 1.5℃ lower than that of the right sub-air guide zone 40. The control device can increase the opening of the air guide vanes 200 in the left sub-air guide zone 30 by 20%. As the temperature difference decreases, the opening of the air guide vanes 200 can be reduced. After 10 minutes, the temperature difference drops to 0.3℃, and the opening of the air guide vanes 200 in the left and right zones becomes consistent.
