The design principle of the civil air defense ventilation casing is mainly based on the principles of fluid mechanics and aerodynamics. It adopts a special pipe structure, through reasonable airflow organization and regulation, so that the air can flow smoothly, and at the same time prevent pollutants from entering the civil air defense project. The civil air defense ventilation casing is also equipped with professional filters and sealing devices, which can effectively filter and block harmful substances and ensure the safety and stability of the ventilation system.
The application range of civil air defense ventilation sleeve is very wide, not only suitable for civil air defense engineering, but also can be applied to other places that need ventilation and air purification, such as hospitals, laboratories, factories, etc. With the continuous development of science and technology, the technology of civil air defense ventilation casing is also constantly updated and upgraded to meet the needs and requirements of different places.
The civil air defense ventilation casing is an indispensable part of the civil air defense project, which ensures the normal operation of the ventilation system in wartime and provides a solid guarantee for the life safety and health of personnel. In the future, with the continuous progress of science and technology and the continuous expansion of application fields, civil air defense ventilation casing will play a more important role to protect people's life safety and health.
