Description

Technical Field

[0001] The invention relates to the field of indoor environment control, and in particular to an air volume adjustable constant temperature and humidity laboratory air supply static pressure system. Background Art

[0002] Constant temperature and humidity laboratories are essential environmental facilities for precision instrument testing, electronic component R&D, and biological cultivation. Their core mission is to maintain the accuracy and stability of internal temperature and humidity parameters. Traditional static pressure air supply systems often use fixed air volume distribution or simple zone control modes, which present significant technical drawbacks. First, static air volume adjustment cannot adapt to the dynamic changes in heat sources within the laboratory (such as equipment heat generation and human activity), resulting in significant temperature and humidity fluctuations in local areas (e.g., temperature deviations can reach ±1.5°C and humidity fluctuations exceed ±5%RH), making it difficult to meet the requirements of high-precision experiments. Second, air volume adjustment relies on manual experience or preset programs, resulting in significant response lag (adjustment times often exceed 5 minutes), which can easily lead to long recovery periods and large fluctuations in temperature and humidity. Third, system energy consumption is high. To meet extreme operating conditions, the system often operates at maximum air volume, and when not fully loaded, the fan's inactive power consumption accounts for over 40%. These issues severely restrict the accuracy and energy efficiency of laboratory environmental control. An intelligent system is urgently needed that can sense heat source distribution in real time, dynamically adjust air volume, and achieve high-precision temperature and humidity control.

DETAILED DESCRIPTION

[0017] In order to provide a further understanding of the purpose, structure, features, and functions of the present invention, the present invention is described in detail below with reference to the embodiments.

[0018] Please refer to Figure 1The present invention provides a constant temperature and humidity laboratory air supply static pressure system with adjustable air volume, the system comprising an air supply static pressure box 1, a heat source sensing device 2 and a data processing module 3; the heat source sensing device 2 is electrically connected to the data processing module 3 by signals; the data processing module 3 is electrically connected to the air supply static pressure box 1 by signals; a driving control device 11 is provided in the air supply static pressure box 1; an adjustable damper 12 is provided on the air supply static pressure box 1 for adjusting the air supply volume according to the instructions of the data processing module 3; the heat source sensing device 2 is used to monitor the temperature in the laboratory in real time and transmit signals to the data processing module 3; the data processing module 3 is used to receive temperature signals, analyze temperature data and issue air volume adjustment instructions to the air supply static pressure box 1 according to the analysis results, and the driving control device 11 controls and adjusts the damper 12.

[0019] The system monitors the laboratory's temperature in real time via a heat source sensor 2 and transmits this data to a data processing module 3. Upon receiving this temperature data, the data processing module analyzes and determines whether the laboratory environment meets preset temperature and humidity standards. If the temperature and humidity exceed the preset range, the system automatically adjusts the air supply to ensure that the laboratory environment maintains a constant temperature and humidity. This makes laboratory environmental control more precise and stable.

[0020] A drive control device 11 is provided in the air supply static pressure box 1, and the damper 12 can adjust the air supply volume according to the instructions of the data processing module 3. The intelligent design avoids the tedious process of traditional manual control and reduces human errors. By automatically adjusting the opening of the damper, the system can dynamically adjust the air volume according to real-time changes in temperature and humidity, thereby maintaining a constant temperature and humidity effect in the laboratory. Automatic adjustment of the air supply volume can not only ensure the stability of the laboratory environment, but also avoid excessive air supply, thereby reducing energy consumption. After the temperature and humidity reach the preset value, the system will reduce unnecessary air supply, optimize energy efficiency, and reduce operating costs.

[0021] Preferably, the damper 12 is provided with a stop bar 121 and an opening control leaf door 122 ; the stop bar 121 and the opening control leaf door 122 are both connected to the drive control device 11 .

[0022] By providing the stop bar 121 and the opening and closing control door 122, the damper's open or closed position can be precisely controlled, improving the accuracy and responsiveness of damper operation. The design of the stop bar 121 and the opening and closing control door 122 prevents the damper from being excessively opened or closed, thereby avoiding potential equipment damage or malfunction. The position can be adjusted in real time by the drive control device 11, ensuring that the system operates within safe parameters.

[0023] The opening and closing of the damper 122 is automatically controlled by the drive control device 11, reducing manual intervention and improving the automation and intelligence level of the system. It is suitable for environments that require long-term stable operation and unattended operation. By accurately controlling the opening and closing of the damper 12, the air flow or airflow distribution can be adjusted more efficiently, avoiding unnecessary energy waste. For example, in a ventilation system, excessive air flow wastes energy, while precise control can maximize energy efficiency. Preferably, the stop bar 121 opens and closes at 1-179 degrees; the opening and controlling leaf doors 122 are evenly distributed in strips; and the width of the stop bar 121 is equal to the width of the opening and controlling leaf doors 122 .

[0024] The bar 121 can precisely open and close between 1 and 179 degrees, allowing the damper 12 to adjust its opening within a very precise range. This high-precision adjustment allows for more accurate control of airflow, meeting the precise airflow requirements of different laboratory environments, ensuring that temperature and humidity remain within predetermined ranges and avoiding over- or under-airflow.

[0025] The strip-shaped, evenly distributed design of the opening and closing control leaf doors 122 helps ensure uniform air flow and avoid environmental fluctuations caused by concentrated or uneven airflow. Uniform airflow distribution can effectively improve the efficiency of air circulation in the laboratory, achieving a more balanced temperature and humidity.

[0026] The width of the bar 121 is equal to the width of the opening and closing control leaf 122, ensuring the stability and symmetry of the damper 12 during opening and closing, and avoiding problems such as unstable airflow or noise caused by an imbalance of the damper 12. This balanced design improves the smoothness of the damper 12 adjustment process, avoids irregular fluctuations in air flow, and enhances system stability.

[0027] The opening and closing angles of the bar 121 range from 1 degree to 179 degrees, providing a very wide adjustment range, allowing the system to flexibly adjust the air supply volume according to real-time needs in the laboratory.

[0028] Preferably, the data processing module 3 is also provided with preset temperature and humidity thresholds. When it is detected that the actual temperature and humidity deviate from the preset values, the air supply volume is automatically adjusted to achieve a constant temperature and humidity effect.

[0029] Data processing module 3 has preset temperature and humidity thresholds. When the actual temperature and humidity deviate from the preset values, the system automatically adjusts them without human intervention. This automated adjustment method greatly improves the efficiency and convenience of the system, maintaining the environment within the ideal temperature and humidity range and reducing human error. The automated process of temperature and humidity deviation monitoring and air volume adjustment can quickly respond to environmental changes and ensure timely adjustments when temperature and humidity deviate from the threshold.

[0030] Preferably, the heat source sensing device 2 includes a distributed temperature and humidity sensor and an infrared thermal imager.

[0031] Distributed temperature and humidity sensors can simultaneously monitor temperature and humidity changes in different areas, providing refined environmental data. This distributed arrangement effectively captures local variations in the environment, ensuring accurate, real-time monitoring of the temperature and humidity conditions of the entire space. Infrared thermal imaging technology can quickly identify and locate heat sources, visually displaying their distribution through temperature images. This is very effective in detecting equipment failures, abnormal temperature rises, or heat leaks, providing early warning and preventing potential safety hazards.

[0032] Combining data from infrared thermal imaging and temperature and humidity sensors enables a more sensitive and accurate response. If temperature and humidity data deviate from preset values or if a heat source anomaly occurs, the system can make timely adjustments, automatically adjusting ventilation, heating, or cooling to maintain a stable environment.

[0033] Preferably, the system monitors the temperature and humidity changes in the regulated area in real time through a closed-loop control algorithm, and dynamically optimizes the opening of the damper 12 to ensure that the temperature fluctuation is ≤±0.2°C and the humidity fluctuation is ≤±2%RH.

[0034] By dynamically optimizing the damper opening, air flow can be precisely adjusted, enabling precise control of temperature and humidity, ensuring temperature fluctuations within ±0.2°C and humidity fluctuations within ±2%RH. This ensures environmental stability, especially in locations with stringent temperature and humidity requirements. Dynamic adjustment of the damper opening automatically optimizes system operating conditions based on actual needs, avoiding inefficient equipment or excessive consumption due to over- or under-regulation. This reduces energy consumption and improves overall system efficiency and cost-effectiveness.

[0035] A control method for a static pressure air supply system in a constant temperature and humidity laboratory with adjustable air volume, the specific steps of the control method are as follows: S1: Real-time monitoring of temperature and humidity; through the heat source sensing device 2, the temperature and humidity in the laboratory are monitored in real time, and the monitoring data is transmitted to the data processing module 3; S2: Comparison of temperature and humidity thresholds; the data processing module 3 receives the temperature and humidity monitoring data of step S1 and compares it with the preset temperature and humidity thresholds; when the temperature and humidity deviate from the preset thresholds, the adjustment program is started; S3: Generate air volume adjustment instructions; the data processing module 3 analyzes and generates air volume adjustment instructions according to the temperature and humidity changes, and controls the air volume adjustment of the air supply static pressure box 1; S4: Adjust the damper to control the air supply; the air supply static pressure box 1 adjusts the opening of the damper 12 by the drive control device 11 according to the air volume adjustment instruction issued by the data processing module 3 to control the air supply volume to achieve the constant temperature and humidity target; S5: Achieve closed-loop constant temperature and humidity; the system uses a closed-loop control algorithm to monitor the temperature and humidity changes in the area in real time and dynamically adjust the damper opening to ensure that the temperature fluctuation does not exceed ±0.2°C and the humidity fluctuation does not exceed ±2%RH, ensuring constant temperature and humidity.

[0036] Specific implementation: A heat source sensing device 2 is installed at key locations in the laboratory. This device includes distributed temperature and humidity sensors and infrared thermal imaging equipment. The temperature and humidity sensors monitor the temperature and humidity within the laboratory in real time, while the infrared thermal imaging equipment captures the distribution of heat sources within the laboratory, enabling a more accurate understanding of environmental changes within the laboratory. The monitored data is wirelessly transmitted in real time to the data processing module 3. Upon receiving the temperature and humidity monitoring data, the data processing module 3 immediately compares it with preset temperature and humidity thresholds. These thresholds are set based on the specific needs of the laboratory and equipment requirements. If the monitored temperature and humidity data deviate from the preset thresholds, the data processing module 3 automatically initiates an adjustment program to prepare for air volume adjustment. The data processing module 3 analyzes the temperature and humidity changes and generates corresponding air volume adjustment instructions. These instructions include increasing or decreasing the air volume, adjusting the air speed, and changing the air direction. Once generated, the instructions are transmitted via electrical signals to the air supply static pressure box 1. Upon receiving the air volume adjustment instructions from the data processing module 3, the air supply static pressure box 1 adjusts the opening of the damper 12 via its internal drive control device 11. The opening adjustment of the damper 12 can be achieved by a motor, a pneumatic device or a hydraulic device. During the adjustment process, the air supply static pressure box 1 will monitor the changes in the air supply volume in real time and make fine adjustments as needed to ensure that the air supply volume reaches the preset value. The system uses a closed-loop control algorithm to monitor the temperature and humidity changes in the laboratory area in real time. By constantly comparing the actual temperature and humidity with the preset thresholds, the system can dynamically adjust the opening of the damper 12 to maintain a constant temperature and humidity effect. In order to ensure control accuracy, the system will also regularly calibrate the temperature and humidity sensors and infrared thermal imaging equipment to reduce errors.

[0037] Furthermore, the present invention employs redundant design for key components, such as the installation of backup sensors and drive devices, to ensure the system continues to operate normally in the event of equipment failure. Secondly, the system has built-in fault warning and diagnostic functions, capable of real-time monitoring of equipment operating status, issuing warning signals when a fault occurs, and providing troubleshooting guidance. Furthermore, through a remote monitoring platform, laboratory temperature and humidity data, equipment operating status, and alarm information can be monitored in real time, facilitating remote monitoring and management by managers.

[0038] Furthermore, a suspension device 10 is provided on the back of the air supply static pressure box 1 to facilitate hanging with the ceiling of the laboratory; the suspension device 10 is symmetrically arranged on the upper surface of the air supply static pressure box 1; symmetrically arranged elliptical docking holes 101 are provided on each side of the suspension device 10; the elliptical docking holes 101 are detachably connected to the docking device preset on the ceiling of the laboratory.

It should be noted that the disclosed embodiments do not limit the scope of the present invention. On the contrary, modifications and improvements that do not depart from the spirit and scope of the present invention are intended to be protected by the present invention.
