Research and design method of pressure difference control in high-level biosafety laboratories

The pressure difference fluctuation in high-level biosafety laboratories is difficult to control due to the high air tightness. This paper analyses the disturbance factors of the pressure difference in the high-level biosafety laboratory, and considers that the key to controlling the pressure difference in the laboratory is to increase the adaptability of the system and adopt the pressure-related valve. This paper puts forward some suggestions and requirements for the control of various disturbance factors, which have been verified in the actual project application.
