实验动物房压差数值模拟与分析

Simulation and Analysis for Air Differential Control of Laboratory Animal Room

为了保证实验动物饲养环境达到相应的标准,需要实验动物房相对外界保持一定的正压。本文模拟分析了实验动物房的内外环境空气压差,首先对迎风面上的压强进行了模拟,总结了迎风面压强变化函数;同时对室内房间之间的压差梯度进行了详细分析;最后总结了为保障其室内外的气流环境安全所必须采取的措施。

In order to guarantee the laboratory animal room air environment security, positive pressure need to keep the indoor between the outdoor. In this paper, pressure differential of laboratory animal room was simulated and analyzed. At first, the pressure differential on the windward side was simulated; the function of the pressure differential on the windward side was draw; at the same time, the pressure differential among the indoor rooms was analyzed detailed; at last, the way to protect the laboratory animal room air environment security was draw.
