Simulation and analysis for laboratory animal room air environment security control system

Abstract

This paper simulated and analyzed the pressure differential of laboratory animal room by CFD software, under a certain wind speed; the windward-side pressure distribution of laboratory animal room was studied; the windward-side pressure differential distribution function was drawn; the corresponding distribution law and max wind pressure point were found. At the same time, the indoor air pressure among the laboratory animal rooms was simulated when the door opened, to find the air pressure differential which can prevent air flow from low-pressure region to high-pressure region, to determine the air pressure differential between indoor and outdoor, and among the laboratory animal rooms, so as to provide certain reference for making code, construction and design, and to decrease positive pressure air change and save energy based on inside air environment achieves requests. © Springer-Verlag Berlin Heidelberg 2014.
