Description

TECHNICAL FIELD

[0001] The present application belongs to the field of environmental control, and particularly relates to a wind curtain type air supply device, a wind curtain type enclosure-free environmental simulation system and a control method thereof. BACKGROUND

[0002] With the continuous progress of science and technology, the demand for experiments and production under specific environmental conditions is increasing, especially in the fields of agriculture, pharmaceuticals, food processing, material science, etc. Precise control of temperature and humidity environment is crucial for product quality and experimental results.

[0003] In the field of environmental control, existing technical solutions include enclosure type environmental control rooms, mobile environmental control cabins and local environmental control systems. The enclosure type environmental control room is to build a heat-insulated enclosure (such as walls and roofs) and equip it with temperature and humidity control equipment to maintain specific environmental conditions. However, the cost is high and the flexibility is poor, which is difficult to adapt to the rapid changes in research and production needs. The mobile environmental control cabin adopts a movable cabin structure and is equipped with temperature and humidity control equipment inside. The cabin is moved to adapt to different experimental or production sites. Although this technical solution improves flexibility, it still relies on physical enclosures and is relatively high in cost and cumbersome to move and arrange. The local environmental control system refers to the simulation of the required environmental conditions in a specific area through local control, such as local air conditioning or humidification systems. However, its control range is limited, and it is difficult to achieve uniform environmental control in a large area or an open space, and it has the problem of low energy efficiency.

[0004] Wind curtain technology, as a new type of air isolation and environmental control method, has been widely used in commercial and industrial fields. The wind curtain forms an invisible barrier through high-speed air flow, effectively isolates the internal and external environments, reduces energy loss, and improves energy efficiency. However, traditional wind curtain technology is mainly used for isolation and energy saving, rather than precise control of environmental parameters, so its application in environmental simulation is limited. Applying wind curtain technology to enclosure-free environmental simulation to achieve precise environmental control in open spaces is still an innovative and challenging task.

[0049] In the embodiment of the application, the wind curtain air inlets 3 are arranged at both ends of each wind curtain pipe 1, and air enters from both ends of the wind curtain pipe 1 at the same time. This symmetrical design not only enhances the stability of the wind curtain, but also optimizes the air flow path and reduces energy loss. More importantly, this design can effectively ensure that the air speed of each wind curtain air inlet 3 is uniform, avoiding the problem of uneven air speed caused by one-sided air inlet, thereby ensuring the uniformity and stability of the air barrier.

On the upper surface of each air curtain duct 1, multiple rectangular air curtain outlets 2 are uniformly arranged. These air curtain outlets 2 take into account the principle of aerodynamics, and through accelerated air injection, a stable air barrier is formed above the air curtain duct 1.

[0060] In the embodiment of the present application, the environmental parameter adjusting device comprises a temperature adjusting device and / or a humidity adjusting device, and the environmental parameter collecting device comprises a temperature sensor and / or a humidity sensor.

[0061] The temperature sensor is used for collecting the temperature in the closed space surrounded by the air curtain formed by the air curtain type air supply device and sending the temperature to the central control unit.

[0063] The central control unit is used for controlling the working state of the temperature adjusting device according to the temperature collected by the temperature sensor and the preset temperature, and controlling the working state of the humidity adjusting device according to the temperature collected by the humidity sensor and the preset humidity.

[0067] As shown in Figure 2 In the embodiment of the present application, the air curtain type non-enclosure environment simulation system is based on the demand for environmental control. Through a series of refined air processing steps, it ensures to provide fresh air with constant temperature and humidity for a specific space. First, the system guides outdoor fresh air into the temperature regulating device according to the preset environmental temperature and humidity parameters. At this stage, the temperature regulating device plays its role to adjust the temperature of the fresh air to the preset temperature, laying the foundation for subsequent processing. Then, the fresh air enters the humidity regulating device. This step is the key to achieving constant humidity. According to actual needs, the system will automatically adjust the operation mode of the humidity regulating device, whether through dehumidification or humidification, to ensure that the humidity of the fresh air reaches the preset humidity, thereby achieving accurate control of humidity. Finally, the fresh air that has undergone temperature and humidity regulation is delivered to the air curtain type air supply device through the air supply pipeline 4. The air curtain type air supply device is designed considering the specific needs of the target space (i.e. the enclosed space surrounded by the air curtain). Its size and layout are carefully designed to ensure that the fresh air can evenly and effectively cover the entire target space. In this way, the system not only provides the required constant temperature and humidity environment for the space, but also achieves the best energy saving and efficiency.

[0068] The air curtain type non-enclosure environment simulation system realizes accurate regulation and stable control of environmental temperature and humidity through intelligent control logic. The system mainly combines artificial intelligence algorithms and PID (Proportional-Integral-Derivative) control logic to ensure the best operation effect.

[0069] The specific control steps are as follows:

[0070] (1) Data collection and real-time monitoring. Through temperature sensors and humidity sensors, the environmental temperature and humidity in the target space are monitored in real time. The air flow in the air supply pipeline 4 is collected by the air volume sensor. Each sensor collects data in real time and sends it to the central control unit.

[0071] (2) Passive control of temperature and humidity in the initial stage:

[0072] 1) According to the preset temperature and real-time monitored temperature data, the system first adjusts the working state of the temperature adjusting device through the PID control algorithm. The fuzzy PID controller adjusts the compressor speed and the opening of the expansion valve in real time according to the error between the current temperature and the preset temperature, so as to quickly respond to temperature changes and ensure that the temperature of the fresh air reaches the preset standard.

[0073] 2) Intelligent adjustment of humidity adjusting device. Use fuzzy PID control to adjust the operation of the humidity adjusting device. Based on real-time monitoring of humidity data, the fuzzy PID controller dynamically adjusts according to the humidity error to ensure that the humidity of the fresh air meets the preset humidity. Artificial intelligence algorithm further optimizes the control process, reducing the response time and over-regulation phenomenon of the system.

[0074] (3) Intelligent distribution of air curtain type air supply device. The fresh air adjusted by temperature and humidity is delivered to the air curtain type air supply device through the air supply pipeline 4. In this stage, the system intelligently adjusts the flow of the air curtain outlet 2 by controlling the speed of the fan according to the size and shape of the target space and the air flow collected by the air volume sensor, so that the height of the closed space formed by the air curtain meets the use requirements. By monitoring the effect of the air curtain in real time, the air flow is dynamically adjusted to ensure uniform distribution of fresh air and achieve the best environmental control effect.

[0075] (4) Determine whether the temperature and humidity of the target space meet the requirements. If the requirements are met, the system will run stably under this setting. If the requirements are not met, repeat the above steps to adjust the temperature and humidity.

[0076] (5) In the stable stage, active control is implemented Figure 3 ): The central control unit processes and analyzes the collected temperature and humidity data using artificial intelligence algorithms, identifies the trend of environmental temperature and humidity changes through artificial neural network models, predicts future temperature and humidity changes, and generates corresponding PID control strategies.

[0077] The specific implementation process of active control is as follows:

[0078] 1) Data collection and processing: Collect temperature, humidity and wind speed data in real time through temperature sensors, humidity sensors and air volume sensors, and normalize the collected data to improve model training effect.

[0079] 2) Artificial neural network model training and prediction: Historical temperature, humidity and wind speed data are sorted into time series input, and long short-term memory network model is used for time series prediction.

[0080] 3) Design and implementation of fuzzy PID controller: Define fuzzy variables, including error (Error), error rate (ΔError) and control output, then design fuzzy control rules based on expert knowledge and experience. The formula for error is:

[0081] e(t) = T set -T current (1)

[0082] The formula for error rate is:

[0083] Δe(t) = e(t) - e(t-1) (2)

[0084] 4) Real-time control strategy combining intelligent prediction and fuzzy control: The prediction results of artificial neural network model are used as the input of fuzzy PID controller, and the control output is generated according to fuzzy control rules and membership functions. The output of fuzzy PID controller is applied to environmental control equipment (such as compressor, valve, water pump, etc.).

[0085] It is worth noting that the present application applies artificial intelligence algorithm to the intelligent control of the system to further improve the control accuracy and energy efficiency ratio of the system. By continuously accumulating historical data, the system can identify the rules of environmental change and optimize the control strategy. Under certain conditions, the system can predict future environmental changes and adjust control parameters in advance, thereby achieving active control of the system.

[0086] The air curtain type environment simulation system without enclosure of the present application realizes efficient and accurate control of environmental temperature and humidity by combining artificial intelligence and PID control logic. The intelligent control logic not only improves the response speed and control accuracy of the system, but also significantly reduces energy consumption, providing reliable technical support for various high-demand environmental control applications.
