Pressure Differential Analysis of a Laboratory Animal Room

Abstract

This paper simulated and analyzed the pressure differential of a laboratory animal room by CFD software. Under a certain wind speed, the windward side pressure distribution of laboratory animal room was studied, and the windward side pressure differential distribution function was drawn. The corresponding distribution law and maximum wind pressure point were found. At the same time, the indoor pressure among the laboratory rooms was studied and simulated when the door opened, to learn what pressure differential can prevent air flow from a low pressure region to a high pressure region. We tested whether the differential pressure is reasonable to regulate the code between the indoors and outdoors, and among laboratory animal rooms, so as to provide a certain reference for code, construction and design, and to decrease positive pressure air change and save energy based on inside air environment requirements.
