The design scheme of laboratory ventilation building is an important link to ensure the air quality of laboratory and the health and safety of laboratory personnel. In the design scheme, the following aspects need to be fully considered. According to the specific conditions and needs of the laboratory, determine the types of ventilation systems, such as natural ventilation, mechanical ventilation and mixed ventilation. Natural ventilation is suitable for some smaller laboratories, mechanical ventilation is suitable for laboratories with high requirements on air volume and temperature, and mixed ventilation combines the advantages of both.

In addition, the layout of the ventilation system should try to ensure that all working areas can get good ventilation effect and avoid dead ends. The direction of ventilation pipes should also be as short and straight as possible, and attention should be paid to the reasonable arrangement with other equipment and pipes.

It is worth noting that the exhaust system should be able to discharge pollutants from the laboratory in time and effectively to ensure that the air quality meets the relevant standards. The air supply system can supplement fresh air according to the needs of the laboratory and maintain good indoor ventilation.

In addition, for high-risk laboratories, such as those involving toxic and flammable substances, it is necessary to consider adding corresponding safety devices, such as odor alarms and explosion-proof equipment, to ensure the safety of experimenters. For example, in the new laboratory of Suzhou Center for Disease Control and Prevention, which has the first P3 biosafety laboratory and dioxin laboratory in southern Jiangsu, the professional team of Big Oak Group has adopted fume hoods and biosafety cabinets. , highly filtered, and customized exhaust system. During the construction of this project, according to the construction function of the laboratory, combined with industry standards, reasonable partition construction was carried out, and a brand-new linkage control concept of air supply and exhaust was adopted to ensure the quality of the experiment and the safety of personnel in all directions.
