关于隔离病房隔离原理的探讨
Isolation principle of isolation wards
摘要：
分析了压差、门的开关、人的进出、温差及缓冲室的设置对隔离病房隔离效果的影响。指出压差仅在门关闭情况下有作用，理论最小压差可定为3 Pa；温差作用下气流有进有出，是压差作用所抵消不了的；缓冲室的动态隔离效果很明显，三室一缓时总隔离系数可达48，五室二缓时总隔离系数可达3 212。总结了隔离病房设计的一般原则。
Abstract：
Analyses the influences of pressure difference, door opening and closing, passing in and out of persons, temperature difference and buffer rooms on isolation effects. Indicates that pressure difference can affect isolation effects only when the door of isolation room is closed and the minimum theoretical value is 3 Pa; the effect of pressure difference can not counteract that of temperature difference because temperature difference can lead to air flowing inward and outward; the dynamic isolation effects of the buffer room is remarkable, and the total isolation coefficient is 48 for three rooms and one buffer room, and 3 212 for five rooms and two buffer rooms. Summarizes the general design principle for isolation wards.
