Laboratory fume hood is an important safety facility in the laboratory, and its design and specifications need to consider the following aspects:

1. Function and Application：

   The main function of laboratory fume hoods is protection and exhaust, which can reduce the risk of laboratory personnel being exposed to harmful chemicals or biological substances.

   It is suitable for chemical experiments, biological experiments, and physical experiments to protect experimenters from harmful gases, vapors, and particulate matter.

2. category：

   According to different application requirements, laboratory fume hoods can be divided into various types such as chemical fume hoods.

3. structural characteristics：

   The structure of a fume hood includes a cabinet body, workbench, windows, exhaust system, etc. It is usually equipped with an adjustable sliding glass window, where researchers can conduct experimental operations while maintaining a good ventilation environment.

4. Design requirements：

   The dust collection capacity of the fume hood should meet certain standards and regulations, and the airflow direction should be towards the laboratory. The laboratory should maintain negative pressure at all times.

   The exhaust and makeup air system should achieve air volume balance, maintain indoor negative pressure of -5pa-10Pa, and prevent harmful gases from escaping.

5. Technical Specifications：

   The ventilation frequency in the laboratory is set at 8-20 times per hour, the air velocity in the branch pipe is set at 6-12m/s, and the air velocity in the main pipe is set at 8-14m/s.

   The design exhaust volume of a single fume hood varies depending on the size of the cabinet, for example, a single 1500mm wide fume hood is designed to have an exhaust volume of 1500m ³/h.

6. Variable Air Volume Control (VAV)：

   The variable air volume control system adjusts the supply and exhaust air volume of the system by changing the opening of the ventilation cabinet in the laboratory, ensuring that regardless of the adjustment window opening, the ventilation cabinet face wind speed can always be accurately controlled at 0.5m/s.

7. safety performance：

   The main purpose of a fume hood is to exhaust harmful gases generated during experiments, protect the health of experimenters, and require a high degree of safety and operability.

   It should have release function, non backflow function, isolation function, and supplementary function.

8. Monitor configuration：

   Laboratory fume hoods are usually equipped with monitors, whose main functions include real-time display of air velocity at the inlet of the fume hood adjustment door, control of manned and unmanned operation modes, and emergency buttons.

9. air distribution：

   The well-designed laboratory fume hood shall ensure that the air velocity on the inlet surface of the regulating door is always kept at 0.5m/s ± 20% during operation, and the surface air velocity is uniform.

10. maintenance：

    Regularly inspect and maintain fume hoods to ensure their performance and safety, including checking exhaust efficiency, door sealing, etc.

The above are the design and specification requirements for laboratory fume hoods to ensure the safety and efficiency of the laboratory.
