Research on simulation and control of the negative pressure gradient of high-level biosafey laboratories
The pressure gradient simulation model for biosafety laboratory is establish with modelica multizone model,the airflow rate and pressure difference balance of core workshop of biosafety laboratory and buffer room are validated by simulation.Quantitative analysis of the pressure gradient during the conversion process with two working conditions were conducted,and suggestions for airflow rate of the exhaust systems are given to guarantee the control of pressure gradient in biosafety laboratories.
