Description

Technical Field

[0001] The invention belongs to the field of environmental control, and in particular relates to an air curtain type air supply device, an air curtain type non-enclosing structure environmental simulation system and a control method thereof. Background Art

[0002] With the continuous advancement 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, materials science, etc. Precise control of temperature and humidity environment is crucial to product quality and experimental results.

[0003] In the field of environmental control, existing technical solutions include enclosure structure type environmental control rooms, mobile environmental control cabins and local environmental control systems. The enclosure structure type environmental control room maintains specific environmental conditions by building thermal insulation enclosure structures (such as walls, roofs) and equipping them with temperature and humidity control equipment, but the cost is high and the flexibility is poor, making it difficult to adapt to the rapid changes in research and production needs. The mobile environmental control cabin adopts a movable cabin structure, equipped with temperature and humidity control equipment inside, and adapts to different experimental or production sites by moving the cabin. Although this technical solution improves flexibility, it still relies on physical enclosure structures, and the movement and layout are cumbersome and the cost is relatively high. The local environmental control system refers to the simulation of the required environmental conditions through local control in a specific area, such as a local air conditioning or humidification system. However, its control range is limited, and it is difficult to achieve uniform environmental control over a large area or the entire open space, and there is a problem of low energy efficiency.

[0004] As a new means of air isolation and environmental control, air curtain technology has been widely used in commercial and industrial fields. The air curtain forms an invisible barrier through high-speed jet air flow, effectively isolating the internal and external environments, reducing energy loss and improving energy efficiency. However, traditional air 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 air curtain technology to environmental simulation without enclosures to achieve precise environmental control of open spaces is still an innovative and challenging topic.

[0005] The above existing solutions have challenges in environmental control of open spaces. Therefore, it is of great research value to develop a new type of environmental simulation system without enclosure structure and use wind curtain technology to achieve precise control.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] The present invention adopts a wind curtain design without an enclosure structure, and a closed plane area is formed by connecting a number of wind curtain ducts end to end. The air outlet direction of the wind curtain outlet on each wind curtain duct has an angle with the plane area, and the air outlet direction is toward the inside of the plane area. Therefore, when the wind curtain air supply device is directly placed on the ground of an open space, each wind curtain duct supplies air diagonally upward, so that the formed wind curtain can enclose a closed space. Therefore, the wind curtain air supply device of the present invention does not require a traditional physical enclosure structure, and can use the wind curtain to form a closed space in an open space.

[0032] Furthermore, the present invention has wind curtain air inlets at both ends of each wind curtain duct, and air enters from both ends of the wind curtain duct at the same time. The symmetrical air inlet design ensures that the wind speed at each wind curtain air inlet is consistent, forming a stable and uniform air barrier, and also optimizes the air flow path, reduces energy loss, achieves efficient energy utilization, reduces operating costs, and solves the problem of uneven wind speed often occurring in traditional air supply systems.

[0033] Furthermore, the air outlet direction of the wind curtain outlet is perpendicular to the surface of the wind curtain duct where the wind curtain outlet is located, ensuring vertical injection of air, optimizing the air flow direction, enhancing the stability and uniformity of the air barrier, reducing energy loss, and improving the air coverage efficiency, thereby solving the problem of energy waste easily generated in traditional air supply systems.

[0034] The wind curtain type environmental simulation system without enclosures of the present invention, first of all, realizes stable control of the environment in a space without enclosures. In an environment without a physical enclosure, the system can accurately control and maintain specific environmental parameters to ensure the stability and consistency of the simulated environment, which is crucial for application scenarios that require high-precision environmental control. Secondly, the wind curtain type environmental simulation system without enclosures can optimize environmental uniformity control.

[0044] 1. Design of air curtain air supply device

[0045] The core of the air curtain technology of the present invention is to build a dynamic air barrier in an open space through a carefully designed air curtain air supply device. This barrier can not only effectively isolate the external environment, but also create an ideal environment of constant temperature and humidity inside.

[0046] The wind curtain type air supply device described in the present invention comprises: a plurality of wind curtain ducts 1, wherein the plurality of wind curtain ducts 1 are connected end to end to form a closed plane area, a wind curtain air outlet 2 is provided on a surface of each wind curtain duct 1, the air outlet direction of the wind curtain air outlet 2 forms an angle with the plane area, and the air outlet direction of the wind curtain air outlet 2 is toward the inside of the plane area; a wind curtain air inlet 3 is provided on each wind curtain duct 1, and a fan is arranged in each wind curtain duct 1.

[0047] The air curtain type air supply device of the present invention does not have an enclosure structure. When in use, the air curtain type air supply device is directly placed on the ground of an open space, and the air curtain duct 1 supplies air obliquely upward, so that the air curtain formed can enclose a closed space. In the closed space formed, the environment is not affected by the outside world, and work such as equipment testing can be completed in the closed space.

[0048] The angle between the air outlet direction of the air curtain outlet 2 of the present invention and the plane area is preferably 50 to 70 degrees.

[0049] In a specific embodiment of the present invention, air curtain inlets 3 are provided at both ends of each air curtain duct 1, and air enters from both ends of the air curtain duct 1 at the same time. This symmetrical design not only enhances the stability of the air curtain, but also optimizes the air flow path and reduces energy loss. More importantly, this design can effectively ensure that the wind speed of each air curtain inlet 3 is consistent, avoiding the problem of uneven wind speed caused by unilateral air intake, thereby ensuring the uniformity and stability of the air barrier.

[0050] In a specific embodiment of the present invention, the air outlet direction of the air curtain outlet 2 is perpendicular to the surface of the air curtain duct 1 where the air curtain outlet 2 is located, thereby ensuring vertical injection of air and enhancing the stability and uniformity of the air barrier.

[0051] In a specific embodiment of the present invention, the length direction of the air curtain outlet 2 is parallel to the length direction of the air curtain duct 1. A plurality of rectangular air curtain outlets 2 are arranged on the air curtain duct 1, and the size of the air curtain outlet 2 is adjustable, so that the system can flexibly adapt to different space layouts and environmental requirements.

[0052] like Figure 1 As shown, in the embodiment of the present invention, the wind curtain type air supply device is mainly composed of two L-shaped wind curtain ducts 1. The two wind curtain ducts 1 are connected end to end to cleverly enclose an approximately closed rectangular area to ensure the effective concentration and directional delivery of air. Wind curtain air inlets 3 are opened at both ends of each wind curtain duct 1. Cold air enters from both ends of the wind curtain duct 1 at the same time, which enhances the stability of the wind curtain, optimizes the air flow path, and reduces energy loss. This design can also effectively ensure that the wind speed of each wind curtain air inlet 3 is consistent, avoiding the problem of uneven wind speed caused by unilateral air intake, thereby ensuring the uniformity and stability of the air barrier. On the upper surface of each wind curtain duct 1, a plurality of rectangular wind curtain air outlets 2 are evenly arranged. The design of these wind curtain air outlets 2 takes into account the principles of aerodynamics. By accelerating the ejected air, a stable air barrier is formed above the wind curtain duct 1. The size and strength of the barrier depends on the flow rate and speed of the air, and both of these can be precisely controlled by adjusting the size of the wind curtain air outlet 2 and the fan power in the wind curtain duct 1. From Figure 1 It can be clearly seen in (a) that the air curtain duct 1 is at a certain angle to the ground. This design is not only beautiful, but more importantly, it optimizes the air flow direction, allowing the air to more effectively cover the area that needs protection. The air outlet 2 of the air curtain is perpendicular to the air curtain duct 1, ensuring the vertical injection of air and enhancing the stability and uniformity of the air barrier. Through the combination of these designs and technologies, the air curtain air supply device can not only achieve efficient environmental isolation and temperature and humidity control, but also show excellent performance in energy saving, providing an ideal solution for various application scenarios that require precise environmental control.

[0053] 2. Intelligent air curtain type non-enclosing structure environment simulation system

[0054] The efficient environmental management solution of the present invention is designed to provide accurate and stable temperature and humidity control for open spaces, and the intelligent air curtain type non-enclosed structure environmental simulation system is an important component. The system realizes real-time monitoring and dynamic adjustment of environmental parameters by integrating advanced sensors, intelligent control algorithms and efficient air curtain type air supply devices.

[0055] The wind curtain type non-enclosure structure environment simulation system of the present invention comprises: the wind curtain type air supply device as described above, the air supply duct 4, the environmental parameter collection device, the environmental parameter adjustment device, the air volume sensor and the central control unit;

[0056] The air inlet of the environmental parameter adjustment device is connected to the outside air, and the air outlet of the environmental parameter adjustment device is connected to the air curtain air inlet 3 of the air curtain type air supply device through the air supply duct 4;

[0057] The environmental parameter acquisition device is used to collect environmental parameters in a closed space surrounded by a wind curtain formed by the wind curtain type air supply device and send them to the central control unit;

[0058] The air volume sensor is used to collect the air flow in the air supply duct 4 and send it to the central control unit;

[0059] The central control unit is used to control the working state of the environmental parameter adjustment device according to the environmental parameters collected by the environmental parameter collection device and the preset environmental parameters, and to control the working state of the fan in the air curtain duct 1 according to the air flow collected by the air volume sensor and the preset flow.

[0060] In a specific embodiment of the present invention, the environmental parameter adjustment device includes a temperature adjustment device and / or a humidity adjustment device, and the environmental parameter acquisition device includes a temperature sensor and / or a humidity sensor;

[0061] The temperature sensor is used to collect the temperature in the closed space surrounded by the air curtain formed by the air curtain type air supply device and send it to the central control unit;

[0062] The humidity sensor is used to collect the humidity in the closed space surrounded by the air curtain formed by the air curtain type air supply device and send it to the central control unit;

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

[0064] When the environmental parameter adjustment device includes a temperature adjustment device and a humidity adjustment device, the air inlet of the temperature adjustment device is connected to the outside air, the air outlet of the temperature adjustment device is connected to the air inlet of the humidity adjustment device via the air supply duct 4, and the air outlet of the humidity adjustment device is connected to the air curtain inlet 3 of the air curtain type air supply device via the air supply duct 4.

[0065] In the embodiment of the present invention, the temperature regulating device also includes an air filter device 5, an evaporator 6, a first expansion valve 7, a second expansion valve 8, a subcooler 9, a solenoid valve 10, a compressor 11, and a condenser 12; the air supply duct is connected to the gas inlet of the evaporator 6 through the air filter device 5, the gas outlet of the evaporator 6 is connected to the air supply duct through another air filter device 5, the steam outlet of the evaporator 6 is connected to the inlet of the condenser 12 through the compressor 11, the outlet of the condenser 12 is divided into two paths, one path is connected to the subcooler 9, and the other path is connected to the subcooler 9 through the first expansion valve 7, the outlet of the subcooler 9 is divided into two paths, one path is connected to the compressor 11 through the solenoid valve 10, and the other path is connected to the liquid inlet of the evaporator through the second expansion valve 8.

[0066] In the embodiment of the present invention, the humidity regulating device includes a humidifying device 13 and a dehumidifying device 14 . The humidifying device 13 includes a fan and a humidifier 15 , and the dehumidifying device 14 includes a fan and a desiccant 16 .

[0067] like Figure 2 As shown, in the embodiment of the present invention, the wind curtain type non-enclosure structure environment simulation system is based on the demand for environmental control, and through a series of refined air processing steps, it ensures that constant temperature and humidity fresh air is provided for a specific space. First, the system guides the outdoor fresh air into the temperature regulating device according to the preset ambient temperature and humidity parameters. At this stage, the temperature regulating device plays its role and adjusts the temperature of the fresh air to the preset temperature, laying the foundation for subsequent processing. Next, the fresh air enters the humidity regulating device. This step is the key to achieving the constant humidity target. According to actual needs, the system will automatically adjust the operating mode of the humidity regulating device, whether through dehumidification or humidification, it can ensure that the humidity of the fresh air reaches the preset humidity, thereby achieving precise control of the humidity. Finally, the fresh air after temperature and humidity adjustment is transported to the wind curtain type air supply device through the air supply duct 4. The design of the wind curtain type air supply device takes into account the specific needs of the target space (i.e., the closed space surrounded by the wind curtain), and 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 can not only provide the required constant temperature and humidity environment for the space, but also achieve the best in energy saving and efficiency.

[0068] The air curtain type non-enclosure structure environment simulation system realizes precise adjustment and stable control of ambient temperature and humidity through intelligent control logic. The system mainly combines artificial intelligence algorithm and PID (proportional-integral-differential) control logic to ensure the best operation effect.

[0069] The specific control steps are as follows:

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

[0071] (2) In the initial stage, temperature and humidity are passively controlled:

[0072] 1) Based on the preset temperature and real-time monitored temperature data, the system first accurately adjusts the working state of the temperature control 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 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 control device. Fuzzy PID control is used to adjust the operation of humidity control device. Based on the real-time monitored humidity data, the fuzzy PID controller dynamically adjusts according to the humidity error to ensure that the humidity of fresh air meets the preset humidity. Artificial intelligence algorithm further optimizes the control process and reduces the response time and over-adjustment of the system.

[0074] (3) Intelligent distribution of air curtain air supply device. The fresh air after temperature and humidity adjustment is delivered to the air curtain air supply device through the air supply duct 4. At this stage, the system intelligently adjusts the flow rate 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 enclosed space formed by the air curtain meets the use requirements. By real-time monitoring of the effect of the air curtain, the air flow rate 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 so, the system operates stably under the setting. If not, repeat the above steps to adjust the temperature and humidity.

[0076] (5) In the stable phase, active control is implemented ( Figure 3 ): The central control unit uses artificial intelligence algorithms to process and analyze the collected temperature and humidity data, identifies the changing trends of ambient temperature and humidity through artificial neural network models, predicts future changes in temperature and humidity, and generates corresponding PID control strategies.

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

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

[0079] 2) Artificial neural network model training and prediction: The historical temperature, humidity and wind speed data are organized into time series inputs, and the 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 change rate (ΔError) and control output, and then design fuzzy control rules based on expert knowledge and experience. The error formula is:

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

[0082] The formula for the error rate of change 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 the artificial neural network model are used as the input of the fuzzy PID controller, reasoning is performed and control output is generated according to the fuzzy control rules and membership functions, and the output of the fuzzy PID controller is applied to environmental control equipment (such as compressors, valves, water pumps, etc.).

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

[0086] The wind curtain type non-enclosure structure environment simulation system of the present invention 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.
