종합병원내 공기감염 예방을 위한 진료부와 로비공간의 기류 분석

Abstract

This study analyzes the types of space in the polyclinic and lobby spaces of hospitals, which are thought to be exposed to secondary airborne infections within hospitals. A hospital, which has space where the human traffic from the polyclinic overlaps with that of the lobby (space type II), was selected as the subject of this study. The air current distribution in the polyclinic and lobby areas are analyzed using the calculation program Star-ccm+. The air current distribution in the existing air-conditioned space is analyzed using T · A · B (Testing, Adjusting, Balancing) measured values. The result proved the possibility of secondary airborne infections caused by mixing of the air currents from the polyclinic and lobby in the upper and middle air layers. Five improvement suggestions in terms of changing the position of air inlets and outlets are proposed in this study. Among them, [ALT-3] the arrangement wherein outlets are placed on the first and third lines and inlets are placed on the second line is expected to significantly reduces the possibility of airborne infections, as the air currents in the lower, middle, and upper layers in the polyclinic and lobby spaces are not intermixed
