[0002] In industrial production environments, precise control of temperature and humidity has a significant impact on product quality and production efficiency. This is particularly true in industries such as textiles, electronics, and pharmaceuticals, where humidity requirements are particularly stringent. While traditional air conditioning units with fan-operated heating systems achieve certain temperature regulation and air purification functions, they still have significant shortcomings in humidification control. Existing systems often use simple steam humidification or wet film humidification methods, which have slow response speeds and low adjustment accuracy, making them difficult to meet the requirements of dynamic humidity changes in complex environments.

[0003] Furthermore, traditional humidification systems are prone to secondary pollution during operation, such as scale deposition and bacterial growth, which seriously impacts air quality and equipment lifespan. Furthermore, the lack of an effective mixing device results in inadequate heat and moisture exchange between fresh air and return air, leading to low overall system thermal efficiency and high energy consumption. These issues not only limit the application of air conditioning units in high-precision environments but also increase operating and maintenance costs. A more efficient and intelligent humidification control method is urgently needed to address these technical bottlenecks.

[0004] More importantly, with the ongoing advancement of smart manufacturing and green factory construction, companies are placing higher demands on the energy efficiency, stability, and intelligence of air conditioning systems. However, existing technologies still have many shortcomings in multi-stage temperature control coordination, airflow organization optimization, and real-time feedback adjustment of the humidification process, making it difficult to achieve refined management of temperature and humidity. Therefore, researching and developing a rationally structured, responsive, energy-saving and environmentally friendly humidification control method for air cabinet heating and air conditioning units has become a critical issue that needs to be addressed in the HVAC field.

[0018] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments. DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] like Figure 1 As shown, Figure 1 This is a schematic diagram of the steps of a humidification control method for a wind cabinet heating and air conditioning unit in one embodiment of the present invention; In one embodiment of the present invention, a humidification control method for a wind cabinet heating and air conditioning unit is provided. The wind cabinet heating and air conditioning unit includes a multi-stage filtration system, a front surface cooler, a vortex mixing device, an intermediate surface cooler, a rear surface cooler, a high-pressure water mist humidification system, and a fan, and includes the following steps: In step S1, the incoming fresh air is purified by a multi-stage filtration system, and the purified fresh air is cooled and dehumidified by a pre-cooler.

[0021] Specifically, the key initial step in the humidification control method is to purify the incoming fresh air through a multi-stage filtration system and cool and dehumidify the purified fresh air with a pre-cooler, which aims to provide a clean basic airflow with controllable temperature and humidity for subsequent airflow processing. In the specific implementation process, the fresh air from the outside first enters the air cabinet heating and air-conditioning unit, and is processed step by step by the multi-stage filtration system to remove large particles of impurities, fine dust, microorganisms and other pollutants in the air in turn, thereby ensuring that the air entering the system meets the set cleanliness standards; then, the purified fresh air is transported to the pre-cooler, where sufficient heat exchange with the cooling medium is achieved to achieve the cooling and dehumidification functions of the air, reduce the moisture content of the air and adjust its temperature to an appropriate range, so as to avoid the subsequent mixing and humidification process caused by excessively high initial humidity, resulting in unstable control or excessive energy consumption. For example, in a typical application scenario such as a textile workshop, if the fiber dust suspended in the air is not effectively filtered, it is very easy to deposit inside the equipment and affect product quality. The introduction of a pre-cooler can effectively control the humidity load of the new air entering the workshop, avoiding the problem of increased yarn breakage rate due to excessive air humidity, thereby ensuring the stability of the production process and the consistency of the finished product quality.

[0022] Step S2: The fresh air after cooling and dehumidification is mixed with the return air through a vortex mixing device to form a three-dimensional spiral vortex mixed airflow.

[0023] Specifically, the vortex mixing device is used to mix the cooled and dehumidified fresh air with the return air to form a three-dimensional spiral vortex mixed airflow. This is an important step in achieving efficient heat and moisture exchange and stable airflow regulation in the humidification control method. Its purpose is to improve the air mixing efficiency and lay the foundation for the subsequent precise control of temperature and humidity. In the specific implementation process, the low-temperature and low-humidity fresh air treated by the pre-cooler and the return air from the workshop intersect inside the vortex mixing device, and under the guidance of a specific structure, a three-dimensional spiral vortex mixed airflow with rotational kinetic energy is formed. This airflow form not only prolongs the contact time between the fresh air and the return air, but also enhances the heat and humidity exchange efficiency between the two, making the mixed air more uniform and stable in temperature and humidity. At the same time, the three-dimensional spiral vortex structure helps to reduce airflow dead corners and local temperature differences, avoid the subsequent temperature and humidity control fluctuations caused by uneven mixing, and thus improve the operating stability and response speed of the entire system. For example, in the actual application of textile workshops, due to the high sensitivity to air temperature and humidity during the production process, if the fresh air and return air are not mixed sufficiently, it is easy to cause problems such as uneven moisture absorption of yarn in local areas and decreased strength. The three-dimensional spiral vortex mixed airflow formed by the vortex mixing device can effectively ensure the uniformity and continuity of the air environment in the workshop, thereby improving the consistency of product quality and the energy efficiency of equipment operation.

[0024] Step S3 , controlling the intermediate surface cooler and the rear surface cooler to perform secondary cooling and temperature control on the three-dimensional spiral vortex mixed airflow according to the temperature and humidity distribution data of the three-dimensional spiral vortex mixed airflow.

[0025] Specifically, controlling the intermediate surface cooler and the rear surface cooler to perform secondary cooling and temperature control on the three-dimensional spiral vortex mixed airflow according to the temperature and humidity distribution data of the three-dimensional spiral vortex mixed airflow is a key step in achieving refined temperature regulation in the humidification control method, which aims to ensure that the mixed airflow has stable and suitable temperature and humidity conditions before entering the humidification link. During the specific implementation process, the system collects the temperature and humidity distribution data of the three-dimensional spiral vortex mixed airflow in real time through high-precision sensors arranged in the air duct, and feeds these data back to the control system. The control system dynamically adjusts the working status of the intermediate surface cooler and the rear surface cooler according to the preset process parameters, so that the mixed airflow completes segmented cooling and constant temperature control when passing through the two cooling units in turn, thereby avoiding the subsequent humidification effect affected by excessive fluctuations in airflow temperature; at the same time, since the three-dimensional spiral vortex mixed airflow itself has good uniformity and heat exchange efficiency, the intermediate surface cooler and the rear surface cooler can play a more efficient role, further improving the energy efficiency and environmental adaptability of the entire system. For example, in the application scenario of a textile workshop, slight changes in air temperature and humidity will directly affect the moisture absorption performance and weaving efficiency of the yarn. If the temperature of the mixed air flow is unstable, the humidification process will be difficult to accurately control. However, through the coordinated regulation of the intermediate surface cooler and the rear surface cooler, the air delivered to the humidification area can be effectively guaranteed to be in the best condition, thereby maintaining the stability of the temperature and humidity in the workshop, and improving the continuity of the production process and the consistency of product quality.

[0026] In step S4, a high-pressure water mist humidification system is used to humidify the three-dimensional spiral vortex mixed airflow after the secondary cooling and temperature control treatment, and the moisture of the humidified three-dimensional spiral vortex mixed airflow is filtered through a honeycomb water curtain, and the air after moisture filtration is input into the target workshop through a fan.

[0027] Specifically, a high-pressure water mist humidification system is used to humidify the three-dimensional spiral vortex mixed airflow after secondary cooling and temperature control. The humidified three-dimensional spiral vortex mixed airflow is then filtered through a honeycomb water curtain. The filtered air is then delivered to the target workshop via a fan, a key step in achieving efficient, clean humidification and stable air supply in this humidification control method. During implementation, the three-dimensional spiral vortex mixed airflow, after precise temperature control by the intermediate and post-cooling coolers, enters the humidification zone. At this point, the high-pressure water mist humidification system uses a high-pressure pump to pressurize water to an atomized state and evenly sprays it into the airflow channel, causing the water mist to quickly evaporate and fully merge with the airflow, thereby achieving a rapid and uniform humidification effect. The airflow then continues to pass through the honeycomb water curtain, which effectively intercepts unevaporated liquid water droplets and tiny impurities in the air, preventing water carryover and ensuring stable, clean, and pollution-free humidity in the output air. Finally, the filtered air is delivered to the target workshop by a fan, maintaining the desired temperature and humidity within the workshop. For example, in the application scenario of a textile workshop, yarn production has extremely strict requirements on air humidity. If the humidity is too low, the fibers will break brittlely, and traditional humidification methods are difficult to achieve rapid response and uniform distribution. The use of a high-pressure water mist humidification system combined with a honeycomb water curtain design can accurately control the humidity in the workshop, improve yarn strength and yield, and avoid equipment corrosion and secondary pollution caused by water in the air, thereby ensuring the stability and safety of the production process.

[0028] In a specific embodiment, the multi-stage filtration system includes a primary efficiency G4 filter and a medium efficiency F8 filter, and the purification of the incoming fresh air by the multi-stage filtration system includes: The incoming fresh air is charged by the electrostatic charge separation device to convert the incoming fresh air into a flow of charged suspended particles, and the coarse particles in the charged suspended particles are intercepted by the primary G4 filter to achieve primary filtration of the fresh air. The fresh air after the first filtration is centrifuged and then filtered through a medium-efficiency F8 filter to remove fine particles, thereby purifying the incoming fresh air.

[0029] Specifically, the multi-stage filtration system includes a primary G4 filter and a medium-efficiency F8 filter. When the system purifies the incoming fresh air, it first uses an electrostatic charge separation device to charge the particulate matter in the air, causing the originally neutral suspended particles to be positively or negatively charged, thereby converting the fresh air flow into a flow of charged suspended particles. Due to the mutual repulsion between charged particles, their distribution in the airflow is more even, and they are more easily adsorbed and captured by subsequent physical filter materials. This not only improves the primary G4 filter's interception efficiency for large particles (particle size ≥5μm), but also effectively reduces filtration resistance and extends the service life of the filter material. On this basis, the primary G4 filter can achieve a single filtration of the fresh air, with a filtration efficiency of over 80%, and can effectively remove coarse particulate pollutants such as pollen, dust, and lint from the air. After primary filtration, fresh air enters the centrifugal separation unit. High-speed rotation generates strong centrifugal force, causing large particles (such as those between 3 and 5 μm) remaining in the airflow to be swept toward the outer wall of the unit due to inertia and settle. This further reduces the airborne particle load and provides a cleaner airflow foundation for the subsequent medium-efficiency F8 filter. This centrifugal separation process preemptively removes over 60% of medium-sized particles from the air, significantly improving the overall filtration system's efficiency and energy savings. The fresh air then enters the medium-efficiency F8 filter, which has a high capture capacity for particles in the 1-3 μm range, achieving a filtration efficiency exceeding 90%. It effectively removes microscopic particles such as bacteria, fine dust, and some viral vectors, achieving deep purification of the fresh air. The multi-stage filtration system works in tandem to ensure that the air quality entering the air conditioning unit meets the high-efficiency filtration requirements of the ISO 16890 ePM2.5 level, providing a clean and stable airflow foundation for subsequent temperature and humidity control and humidification. For example, in a typical textile workshop, the air often contains large amounts of fiber debris, lint, and fine dust. If these impurities are not effectively removed and enter the air conditioning system directly, they will not only clog the surface cooler and affect heat exchange efficiency, but may also adhere to the yarn surface, causing increased breakage rates and fabric defects. The multi-stage filtration system, which includes an electrostatic charge separation device, a primary G4 filter, a centrifugal separation device, and a medium-efficiency F8 filter, can achieve step-by-step interception and efficient purification of various types of particulate matter in the air, maintaining a high level of air quality in the workshop, thereby improving production stability and product qualification rates, and meeting the stringent environmental cleanliness requirements of high-precision production processes.

[0030] In a specific embodiment, the method of using a pre-cooler to cool and dehumidify the purified fresh air includes: Detecting the temperature and humidity of the preliminarily purified fresh air using a temperature and humidity sensor to obtain initial temperature and humidity parameters, and adjusting the pre-cooler based on the initial temperature and humidity parameters to cool the preliminarily purified fresh air to form preliminarily cooled fresh air, and performing thermodynamic analysis on the preliminarily cooled fresh air to obtain enthalpy change data; Condensate is collected from the preliminarily cooled fresh air by a condensate collection device to obtain condensate amount data, and the working parameters of the pre-cooler are adjusted based on the enthalpy change data and the condensate amount data to cool and dehumidify the preliminarily cooled fresh air.

[0031] Specifically, the use of a pre-cooler to cool and dehumidify the purified fresh air is an important step after completing the initial purification of the fresh air. Its purpose is to provide a stable airflow foundation with controllable temperature and humidity for subsequent air mixing and humidification control. In the specific implementation process, the system first uses a temperature and humidity sensor to perform real-time temperature and humidity detection on the preliminary purified fresh air after processing through the multi-stage filtration system to obtain initial temperature and humidity parameters including temperature, relative humidity, and dew point temperature. For example, in the hot and humid environment of summer, the purified fresh air entering the system may have an initial state of 35°C and a relative humidity of 80%. In this state, the air moisture content is as high as about 20g / kg of dry air. If it is not effectively processed, it will directly affect the stability of the subsequent mixed airflow and the accuracy of humidification control. Based on the above initial temperature and humidity parameters, the control system will dynamically adjust the operating mode of the pre-cooler, such as adjusting the cold water flow, heat exchange area or operating time, so that the preliminary purified fresh air is cooled and dehumidified when passing through the device, forming preliminary cooled fresh air. During this process, the air temperature can be reduced to around 16-18°C, approaching or reaching the dew point temperature, which causes some of the water vapor in the air to condense into liquid water droplets, achieving a dehumidification effect. To further verify and optimize this process, the system also performs a thermodynamic analysis on the initial cooled fresh air and calculates its enthalpy change data, that is, the difference in heat released from the air from its initial state to the cooled and dehumidified state. Taking fresh air with an initial enthalpy value of approximately 90kJ / kg of dry air as an example, after being treated by the pre-cooler, its enthalpy value can be reduced to approximately 45kJ / kg of dry air, indicating a significant decrease in the energy level of the air, achieving effective energy regulation. At the same time, the system collects the condensed water generated during the initial cooling process through a condensate collection device and measures the condensed water volume data. For example, under typical operating conditions, the amount of condensed water corresponding to the fresh air processing volume of approximately 2.5~3L / m³ / s can be collected every hour. These data, together with the enthalpy change data, are input into the control system as feedback signals to dynamically adjust the operating parameters of the pre-cooler, such as adjusting the inlet and outlet temperatures and flow rates of the chilled water or extending the cooling time, to ensure that the cooling and dehumidification effects always meet the set targets. This closed-loop control mechanism not only improves the accuracy of the system response, but also avoids problems such as overcooling or insufficient dehumidification caused by environmental fluctuations, thereby improving overall energy efficiency. For example, in the application scenario of a textile workshop, since yarn is extremely sensitive to air humidity during processing, excessively high humidity can cause problems such as fiber moisture absorption and expansion, adhesion, etc., affecting the quality of the finished product; while too low humidity can cause fiber brittleness and static electricity accumulation. Therefore, by using a pre-cooler to precisely cool and dehumidify the purified fresh air, the initial state of the air entering the system can be effectively controlled, maintaining it within an ideal range such as 18°C ​​and 60% relative humidity, providing stable airflow conditions for subsequent eddy current mixing, secondary temperature control, and high-pressure water mist humidification, thereby ensuring the continuity of the temperature and humidity environment in the workshop and the consistency of process requirements, thereby improving production efficiency and product quality.

[0032] In a specific embodiment, the vortex mixing device is used to mix the cooled and dehumidified fresh air with the return air to form a three-dimensional spiral vortex mixed airflow, including: Performing velocity vector distribution detection on the fresh air after cooling and dehumidification to obtain fresh air velocity field distribution data, and performing pressure gradient measurement on the return air to obtain a return air dynamic pressure map; Based on the fresh air velocity field distribution data and the return air dynamic pressure map, the temperature and humidity regulated fresh air and return air are directionally guided by an adjustable guide vane array in a vortex mixing device to form a premixed airflow; The premixed airflow is accelerated and sheared by utilizing the Venturi effect structure channel in the vortex mixing device to form a high turbulent kinetic energy mixed airflow; A swirl generator applies controllable angular momentum disturbance to the high turbulent kinetic energy mixed airflow to generate a three-dimensional spiral vortex mixed airflow, wherein the three-dimensional spiral vortex mixed airflow has spatial continuity and presents periodic velocity fluctuations along the axial direction.

[0033] Specifically, the vortex mixing device mixes the cooled and dehumidified fresh air with the return air to form a three-dimensional spiral vortex mixed airflow, which is the core link in achieving efficient and uniform heat and moisture exchange in the entire humidification control process. In the specific implementation process, the velocity vector distribution of the cooled and dehumidified fresh air after being processed by the pre-cooler is first detected. Using multiple sets of laser velocity sensors or hot wire anemometers placed in the air duct, the system acquires velocity and direction data of the fresh air flow at different cross-sections, thereby constructing a complete fresh air velocity field distribution data. For example, under typical operating conditions, the average velocity of the fresh air before entering the vortex mixing device is approximately 3.5 m / s, with a trend of gradually decreasing along the main flow direction. Simultaneously, the system also measures the pressure gradient of the return air from the target workshop, using multiple high-precision differential pressure sensors to collect dynamic pressure maps of the return air at different locations to analyze its energy distribution. Typically, the return air pressure fluctuates within a range of ±50 Pa and exhibits certain periodic variations affected by the operating status of the equipment within the workshop. Based on the fresh air velocity distribution data and the return air dynamic pressure map, the control system calculates and adjusts the operating angle and opening of the adjustable guide vane array in the vortex mixer in real time, ensuring that the fresh air and return air converge and merge at the optimal angle of incidence and velocity. The guide vane array consists of several independently adjustable metal blades that automatically adjust their deflection angle based on real-time feedback from airflow parameters. The angle is typically set within a range of 15° to 45° to ensure a uniform premixed flow when the two airflows converge. This directional guidance not only improves airflow mixing efficiency but also effectively reduces local vortices and energy losses caused by large velocity differences. The premixed air then enters the Venturi-effect structured channel of the vortex mixer. In this region, the airflow velocity is further increased to 6-8 m / s due to the sudden contraction and expansion of the channel's cross-sectional area. This region also generates a strong shearing effect, rapidly breaking up the interface between the fresh air and return air, allowing for thorough mixing and forming a mixed flow with high turbulent kinetic energy. The turbulent kinetic energy value at this stage can reach about 2.5~3.0 m² / s², which significantly enhances the diffusion rate and heat transfer efficiency between air molecules, and provides a more uniform and stable airflow foundation for subsequent temperature and humidity control. Finally, the high turbulent kinetic energy mixed airflow continues to enter the swirl generator area. The device is equipped with a plurality of inclined guide grooves or swirl blades arranged in a ring, which can exert controllable angular momentum disturbance on the airflow, so that it obtains a rotational component while moving axially, and finally generates a three-dimensional spiral vortex mixed airflow with spatial continuity. The airflow exhibits periodic velocity fluctuation characteristics in the axial direction. For example, there can be 3 to 5 velocity peak changes per meter length, and its rotation frequency can be maintained between 20 and 40 Hz, ensuring that the temperature and humidity of the mixed airflow are highly consistent across the entire cross section.This three-dimensional spiral structure not only prolongs the residence time of the airflow in the mixing chamber, but also promotes micro-scale mixing within the airflow, so that the temperature and humidity deviations are controlled within ±0.5°C and ±3%RH. For example, in actual applications in textile workshops, a large amount of fiber dust and heat will be generated inside the workshop due to the yarn processing process, resulting in a certain concentration of fine particulate matter and high waste heat in the return air. If the fresh air and return air are not fully mixed, it will cause local uneven temperature and humidity, which will in turn affect the moisture absorption performance of the yarn and cause problems such as increased breakage rate. Through the step-by-step treatment of the above-mentioned vortex mixing device, not only can the efficient and uniform mixing of fresh air and return air be achieved, but also the waste heat resources in the return air can be fully utilized without affecting the air quality, reducing the subsequent temperature control energy consumption by about 15% or more, while ensuring the stability and continuity of the air environment in the workshop, meeting the stringent requirements of high-precision production processes for air quality.

[0034] In a specific embodiment, based on the fresh air velocity field distribution data and the return air dynamic pressure map, the adjustable guide vane array in the vortex mixing device is used to directionally guide the fresh air and return air after temperature and humidity adjustment to form a premixed airflow, including: Performing vorticity gradient analysis on the fresh air velocity field distribution data to extract the vortex intensity distribution characteristics in the mainstream direction, and performing Fourier frequency domain analysis on the return air dynamic pressure spectrum to identify the main frequency band of pressure fluctuations. Based on the vortex intensity distribution characteristics and the main frequency band information of pressure fluctuations, constructing the airflow coupling dynamic boundary conditions; The airflow coupled dynamic boundary conditions are numerically solved by an aerodynamic optimization calculation module to generate a guide vane angle configuration matrix, and the guide vane angle configuration matrix is ​​input into a servo drive controller to drive the adjustable guide vane array to deploy according to a preset angle to form an airflow kinetic energy channel with guiding characteristics; The airflow kinetic energy channel is used to impose directional airflow constraints on the temperature- and humidity-adjusted fresh air and return air, respectively, so that the two airflows of the temperature- and humidity-adjusted fresh air and return air form a controllable deflection angle and a speed matching gradient before entering the mixing cavity, thereby forming a two-way airflow; The non-steady-state flow field control technology is used to perform local disturbance excitation on the intersection area of ​​the two-way airflow to stimulate the shear instability effect of the airflow interface and form a premixed airflow.

[0035] Specifically, based on the fresh air velocity field distribution data and the return air dynamic pressure map, the adjustable guide vane array in the vortex mixing device directs the temperature- and humidity-adjusted fresh air and return air to form a premixed airflow. This is a key technical approach for achieving efficient and controllable air mixing. In its implementation, the system first performs vorticity gradient analysis on the fresh air velocity field distribution data. This involves using computational fluid dynamics (CFD) algorithms to identify vortex structures in the collected three-dimensional velocity vector field and extract the vortex intensity distribution characteristics of different regions along the mainstream direction. For example, under typical operating conditions, the fresh air flow may contain multiple local vortex regions, with vortex intensities ranging from 0.5 to 1.2 s⁻¹. This information provides important dynamic basis for subsequent optimization of the diversion strategy. Simultaneously, the system also performs Fourier frequency domain analysis on the return air dynamic pressure map to identify the dominant frequency band of pressure fluctuations and understand the dynamic characteristics of the return air flow. For example, return air pressure fluctuations are primarily concentrated in the 0.5-3 Hz range, indicating that they are significantly affected by the start-up and shutdown cycles of workshop equipment and exhibit certain low-frequency oscillation characteristics. Based on the above-mentioned vortex intensity distribution characteristics and pressure fluctuation main frequency band information, the system constructs the airflow coupling dynamic boundary conditions, which comprehensively consider the speed difference between the fresh air and the return air, the pressure gradient and the turbulent energy distribution, and provide a precise control basis for the subsequent guide vane angle configuration. Subsequently, the aerodynamic optimization calculation module numerically solves the constructed airflow coupling dynamic boundary conditions and generates a matrix model containing multiple guide vane angle configuration parameters. The model dynamically adjusts the angle settings of each guide vane according to the real-time detected airflow state. The general setting range is 10°~60°, ensuring that each guide vane can be deployed according to the optimal airflow matching principle, and the guide vane angle configuration matrix is ​​input into the servo drive controller to achieve precise control of the adjustable guide vane array. The resulting kinetic energy channel exhibits excellent guiding properties, imposing directional flow constraints on both the temperature- and humidity-conditioned fresh air and return air, respectively. This results in a controllable deflection angle (typically set between 8° and 15°) and velocity matching gradient (e.g., fresh air velocity of 4.2 m / s and return air velocity of 3.8 m / s) before entering the mixing chamber. This effectively reduces energy loss at the intersection of the two airflows and improves mixing efficiency. Furthermore, the system employs unsteady flow field manipulation techniques to locally perturb the intersection of the two airflows. For example, high-frequency micro-perturbations (approximately 50-100 Hz) are applied to the airflow interface via micro-pulsed nozzles or vibrating diaphragms to stimulate shear instabilities at the airflow interface. This induces microscopic perturbations and penetration of the two airflows before they fully mix, thereby forming a premixed flow with initial uniformity. This premixing process not only enhances the subsequent shear acceleration in the Venturi channel and the angular momentum injection by the swirl generator, but also significantly reduces mixing time, completing the entire mixing process in approximately 0.8 seconds, significantly improving the system's responsiveness and adaptability.For example, in the application scenario of a textile workshop, due to the fiber dust and heat generated during the production process, the return air temperature is usually 3~5℃ higher than the fresh air, and there is also a relative humidity difference of about 10%RH. If the fresh air and return air are not effectively matched and guided, it is very easy to cause local temperature and humidity fluctuations in the mixed airflow, affecting the subsequent temperature control and humidification effects. However, the above-mentioned method based on airflow dynamics modeling and intelligent diversion control can achieve real-time perception and active regulation of complex airflow states, so that the air finally delivered to the workshop always maintains a stable temperature and humidity environment, ensuring the consistency of yarn processing quality and production continuity, and fully meeting the strict requirements of high-precision processes for air quality.

[0036] In a specific embodiment, controlling the intermediate surface cooler and the rear surface cooler to perform secondary cooling and temperature control on the three-dimensional spiral vortex mixed airflow according to the temperature and humidity distribution data of the three-dimensional spiral vortex mixed airflow includes: Based on the temperature and humidity distribution data of the three-dimensional spiral vortex mixed airflow, the mixed airflow is cooled in different zones using the multi-stage refrigeration coils of the intermediate surface cooler to form a preliminary cooling airflow; wherein the preliminary cooling airflow has a uniform temperature gradient; Measuring turbulence intensity of the preliminary cooling airflow to obtain turbulence characteristic parameters, and based on the turbulence characteristic parameters, performing directional vortex enhancement processing on the preliminary cooling airflow through a vortex inducing device to form an enhanced heat exchange airflow; wherein the enhanced heat exchange airflow has enhanced heat transfer efficiency; The enhanced heat exchange airflow is temperature-detected using a thermocouple array to obtain temperature fluctuation data. Based on the temperature fluctuation data, the enhanced heat exchange airflow is subjected to secondary cooling by a precision cooling capacity adjustment unit of a post-cooler to form a temperature-regulated airflow; wherein the temperature fluctuation amplitude of the temperature-regulated airflow is significantly reduced; A heat flux density analysis is performed on the temperature-controlled airflow to obtain heat flux distribution characteristics, and based on the heat flux distribution characteristics, the temperature-controlled airflow is temperature-controlled by a temperature equalizer.

[0037] Specifically, controlling the intermediate surface cooler and the rear surface cooler based on the temperature and humidity distribution data of the three-dimensional spiral vortex mixed airflow to perform secondary cooling and temperature control on the three-dimensional spiral vortex mixed airflow is a key step in achieving precise temperature control of the air-conditioning system. In the specific implementation process, the temperature and humidity distribution data of the three-dimensional spiral vortex mixed airflow is first collected in real time by multi-point temperature and humidity sensors arranged in the air duct. For example, under typical operating conditions, the initial temperature of the mixed airflow is about 22°C and the relative humidity is 65%RH. Due to the existence of its three-dimensional spiral structure, there are certain local temperature differences (±1.2°C) and humidity fluctuations (±4%RH) within the airflow. Based on this data, the system uses the multi-stage refrigeration coils in the intermediate surface cooler to perform zoned cooling on the mixed airflow, applying differentiated cooling capacity in different areas, so that the airflow is gradually cooled and tends to be uniform on each cross-section, forming a preliminary cooling airflow. After passing through the intermediate surface cooler, the temperature of this initial cooling airflow drops to approximately 17°C, while the humidity rises to 75% RH. The temperature gradient is effectively compressed to within ±0.5°C, significantly improving subsequent temperature control accuracy. To further enhance heat transfer efficiency, the system then measures the turbulence intensity of the initial cooling airflow, using a hot-wire anemometer or PIV particle image velocimetry to obtain turbulent kinetic energy parameters. For example, the current turbulent kinetic energy value is approximately 1.8 m² / s². Based on these turbulence characteristic parameters, the control system activates the vortex induction device. By adjusting the guide vane angle (typically set between 20° and 35°), it imparts directional disturbances to the airflow, enhancing its rotational kinetic energy and heat transfer rate, thereby generating an enhanced heat transfer airflow with higher heat transfer efficiency. At this stage, the turbulent kinetic energy of the airflow can be increased to over 2.5 m² / s², significantly increasing the contact area and heat transfer rate between the air and the cooling coil, laying a solid foundation for subsequent precise temperature control. The system then uses a densely packed array of thermocouples to monitor the temperature of the enhanced heat exchange airflow, collecting temperature fluctuation data and adjusting the operating state of the post-cooling unit's precision cooling capacity control unit accordingly. For example, if periodic temperature fluctuations (frequency approximately 0.5Hz, amplitude ±0.8°C) are detected in the airflow, the system automatically adjusts the chilled water flow rate (typically within a range of 0.8-1.2 L / min) to achieve secondary, precise cooling of the airflow. The resulting temperature-controlled airflow maintains a stable temperature of 15°C ±0.2°C and humidity around 80% RH, significantly reducing temperature fluctuations and meeting the requirements of a high-precision process environment. Finally, the system analyzes the heat flux density of the temperature-controlled airflow, identifying its heat flux distribution characteristics across different cross-sections. For example, heat flux density variations across a cross section can reach as high as 80W / m². Based on this data, the temperature equalizer uses its built-in micro-heating / cooling modules to compensate for localized low or high temperatures, ensuring a highly consistent temperature distribution across the entire airflow, thus achieving final temperature control.For example, in textile workshops, yarn production is extremely sensitive to air temperature fluctuations. If the airflow temperature fluctuates by more than ±1°C, it will directly affect the fiber's moisture absorption and weaving quality. However, the aforementioned method, which coordinates temperature and humidity distribution data, turbulence characteristics, and heat flow distribution, enables micron-level control of air supply temperature, ensuring the stability of the workshop's air environment and improving product quality consistency and equipment reliability.

[0038] In a specific embodiment, the method of performing zone cooling on the mixed airflow based on the temperature and humidity distribution data of the three-dimensional spiral vortex mixed airflow using the multi-stage refrigeration coil of the intermediate surface cooler to form the preliminary cooling airflow includes: Performing spatial interpolation processing on the temperature and humidity distribution data of the three-dimensional spiral vortex mixed airflow to obtain a temperature field distribution map; Based on the temperature field distribution diagram, the cooling load of the multi-stage refrigeration coils of the intermediate surface cooler is distributed to obtain a cooling load distribution matrix, and the refrigeration coil operating parameters are set according to the cooling load distribution matrix; Performing zone cooling processing on the mixed airflow according to the operating parameters of the refrigeration coil to form zone cooling airflow, and measuring the turbulence intensity of the zone cooling airflow to obtain turbulence intensity data; Based on the turbulence intensity data, flow stability analysis is performed on the partitioned cooling airflow to obtain flow stability parameters, and fine-tuning cooling treatment is performed on the partitioned cooling airflow using the flow stability parameters to form a preliminary cooling airflow.

[0039] Specifically, the system uses the temperature and humidity distribution data of the three-dimensional spiral vortex mixed airflow to perform zoned cooling of the mixed airflow using the multi-stage refrigeration coils of the intermediate surface cooler to form a preliminary cooling airflow. This is a key step in achieving efficient and precise temperature control. In its implementation, the system first spatially interpolates the collected temperature and humidity distribution data of the three-dimensional spiral vortex mixed airflow. Using a high-precision algorithm, the data from discrete measurement points is expanded into a continuous temperature field distribution map, clearly reflecting the temperature differences and heat load distribution across the entire airflow cross section. For example, under certain operating conditions, the mixed airflow may contain localized high-temperature zones (e.g., 23°C) and low-temperature zones (e.g., 19°C), with an overall temperature difference of up to ±2°C. The humidity is concentrated around 65% RH, exhibiting a certain degree of spatial non-uniformity. Based on this temperature field distribution map, the control system further distributes the cooling load among the multi-stage refrigeration coils in the intermediate surface cooler, generating a cooling load distribution matrix. This matrix sets the cooling intensity for each zone based on its initial temperature. For example, high-temperature zones are allocated a higher cooling capacity (e.g., 2.5 kW per square meter), while low-temperature zones receive a lower cooling capacity (e.g., 1.2 kW per square meter). This prevents energy waste from overcooling or the risk of condensation from localized overcooling. This cooling load distribution matrix is ​​then input into the PLC control unit, which uses it to set the cooling coil operating parameters, including chilled water flow, valve opening, and heat exchange time, to ensure that the cooling effect in each zone closely matches actual needs. Once these parameters are set, the system uses these cooling coil operating parameters to perform zone-by-zone cooling of the three-dimensional spiral vortex mixed airflow, gradually stabilizing the originally uneven temperature and humidity distribution of the airflow and forming a stratified, zoned cooling airflow. At this point, the overall airflow temperature can be reduced to approximately 18°C, although slight local temperature variations (±0.8°C) may still exist. To further optimize the airflow, the system then measures the turbulence intensity of the zoned cooling airflow, using a hot-wire anemometer to obtain turbulent kinetic energy data. For example, the current turbulent kinetic energy value is approximately 1.6 m² / s², indicating some disturbance within the airflow, which could affect subsequent temperature control stability. Based on this turbulence intensity data, the system then performs flow stability analysis and calculates flow stability parameters reflecting the airflow's motion. For example, a Reynolds number of Re≈4200 indicates that the airflow is in a transitional state and not yet fully stabilized. Based on this information, the control system fine-tunes the cooling flow in the zoned cooling airflow, applying a small amount of cooling energy (approximately 0.3 kW / m²) to areas of high turbulence to suppress airflow disturbances and promote homogenization of the velocity and temperature fields. This ultimately results in a more consistent and less volatile initial cooling airflow. The temperature remains stable within a range of 17.5°C ± 0.3°C, and the humidity is elevated to approximately 72% RH. This demonstrates excellent flow stability and thermodynamic consistency, providing an ideal foundation for subsequent enhanced heat exchange and precise temperature control.For example, in textile workshops, even slight changes in air temperature can directly affect the yarn's moisture absorption and weaving efficiency. Excessive fluctuations in the airflow temperature can lead to increased fiber breakage or static electricity accumulation. The aforementioned zoned cooling strategy, based on a combination of temperature field distribution maps, a cooling load allocation matrix, and flow stability analysis, enables precise control of complex airflow structures. This ensures that the air ultimately delivered to the workshop maintains a stable temperature and humidity environment, effectively ensuring the continuity of the production process and the consistency of product quality, and meeting the stringent requirements of high-precision production processes for air conditioning systems.
