In the construction and operation of laboratories, there is a crucial aspect that is often overlooked but actually has a significant impact on laboratory safety, the health of laboratory personnel, and the accuracy of experimental results. That is the laboratory ventilation system. As Guangzhou Cleanroom Construction Co., Ltd., specializing in the production of purification equipment, we will talk to you today about the engineering design of the laboratory ventilation system.
I. Why is the Laboratory Ventilation System So Important?
1. Ensure Personnel Health
Various harmful gases, dust, and microorganisms are often generated in laboratories. Without an effective ventilation system, these pollutants will accumulate indoors. Laboratory personnel are highly likely to suffer from respiratory diseases, poisoning, and other health problems if they are exposed to such an environment for a long time. A good ventilation system can timely exhaust these pollutants and introduce fresh air, providing a safe and healthy working environment for laboratory personnel.
2. Ensure Experimental Accuracy
Some experiments have extremely high requirements for environmental temperature, humidity, air quality, etc. The ventilation system can adjust the air parameters in the room, maintain a stable experimental environment, avoid interference with experimental results due to environmental factors, and ensure the accuracy and reliability of experimental data.
3. Prevent Safety Accidents
Many chemical experiments can produce flammable and explosive gases. If the ventilation is poor, these gases may reach a certain concentration and may cause explosions or fires when encountering a fire source. The ventilation system can timely exhaust flammable and explosive gases outdoors, reduce safety risks, and ensure the safety of the laboratory.
II. Design Key Points of the Laboratory Ventilation System
1. Air Volume Calculation
Accurately calculating the ventilation volume required by the laboratory is the basis for designing the ventilation system. Factors such as the area, height of the laboratory, the quantity and types of experimental equipment, and the amount of pollutants generated by experimental operations need to be considered. Generally, the ventilation volume of the laboratory should ensure that the air change rate is about 8 - 15 times per hour, but the specific value still needs to be accurately calculated according to the actual situation.
2. Selection of Ventilation Methods
Common ventilation methods include natural ventilation and mechanical ventilation. Although natural ventilation is energy - saving and cost - effective, it is greatly restricted by natural conditions and the ventilation effect is unstable. Mechanical ventilation can force air exchange through equipment such as fans, and the ventilation effect is reliable, which is a commonly used ventilation method in laboratories. Mechanical ventilation can be further divided into general ventilation and local ventilation. General ventilation is suitable for laboratories where pollutants are evenly distributed and can ventilate the entire space; local ventilation is aimed at areas where pollutants are more concentrated, such as fume hoods and biosafety cabinets. Pollutants are directly exhausted outdoors through local exhaust devices, which is more efficient.
3. Selection of Ventilation Equipment
Select appropriate ventilation equipment according to the ventilation volume and ventilation method. The fan is the core equipment of the ventilation system. A fan with appropriate power, low noise, and stable operation should be selected according to parameters such as the required air volume and air pressure. The selection of fume hoods is also crucial. Performance indicators such as their material, sealing performance, and air velocity adjustment need to be considered to ensure that pollutants can be effectively captured and exhausted. In addition, corresponding accessories such as air ducts, valves, and filters need to be equipped to ensure the normal operation of the ventilation system.
4. Airflow Organization Design
Reasonable airflow organization can ensure the maximization of the ventilation effect. When designing, the positions, shapes, and sizes of air supply outlets and exhaust outlets need to be considered to make the indoor air form a reasonable flow path, avoid the occurrence of air stagnation areas, and ensure that pollutants can be smoothly exhausted outdoors.
