摘要
采用Modelica多区模型建立生物安全实验室压力梯度仿真模型,对生物安全实验室核心工作间及其缓冲间等区域进行风量及压差平衡模拟验证,定量分析开门、设备排风两种常见工况转换过程中房间压力梯度变化情况,为排风系统风量控制提供建议,确保生物安全实验室压力梯度控制.
Abstract
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.
