平疫结合型医院病区通风系统设计思考
Thinking on ventilation system design of wards in hospitals combined with peacetime and epidemic periods
摘要：
为有效应对突发传染病疫情，未来医院需要兼顾平疫2种功能。根据综合医院标准病区的平疫医疗功能转换，指出医院病区平时应是健康通风，疫情时应是安全通风。分析了健康通风与安全通风的区别和转换要求，探讨了平疫结合型医院病区通风系统实现健康与安全功能转换的设计方法，重点是压力要求、通风量需求、气流组织、通风系统分区和形式、管道设计、机组选型及系统控制等方面，使一套系统通过运行切换或简单改造实现平疫状态下的不同通风需求。
Abstract：
In order to effectively deal with the outbreak of infectious diseases, future hospitals should take into account both peacetime and epidemic prevention functions. According to the conversion of medical function in the standard ward of general hospital in peacetime and epidemic periods, points out that the hospital ward should be respiratory healthy ventilation in peacetime and respiratory safety ventilation in epidemic periods. Analyses the differences and conversion requirements between respiratory health ventilation and respiratory safety ventilation, and discusses the design method of the ward ventilation system of the hospital combined with peacetime and epidemic periods to realize the conversion of healthy and safety functions, focusing on pressure requirements, ventilation demand, air distribution, ventilation system partition and form, pipeline design, unit selection and system control, so that a set of system can realize different ventilation requirements in peacetime and epidemic periods through operation switching or simple transformation.
