모듈 타입별 음압병실의 기류해석을 통한 격리성능 검토 연구

Abstract

In this study, a preliminary review was conducted on the module type and problem-causing factors of the infill-type modular negative pressure field. Through CFD analysis, isolation performance for various ward types was quantitatively reviewed and the impact of contaminated air on adjacent room was identified. Due to the highly variable nature of the infill method, single-person room and double-person room were divided into unit modules to examine indoor airflow and inter-space pressure differential, and then a combination module was constructed by adjacent unit modules, and the degree of contaminated air leakage was analyzed depending on whether the interlock was open or not. The simulation results, during normal operation of each unit module, the pressure distribution appears in the following order : clean corridor> anteroom > contaminated corridor> isolation room> toilet. On the other hand, during abnormal operation due to interlock opening, it was confirmed that the isolation room (IR) and space outside the IR momentarily took the form of equal pressure and air leaked
