渗透风对负压隔离病房室内温湿度的影响
Influence of infiltration air on indoor temperature and humidity in negative pressure isolation wards
摘要：
以武汉市某传染病医院应急楼的顶层负压隔离病房楼层为例,探讨了负压隔离病房渗透风的来源及其空气处理状态点对病房内温湿度的影响。重点研究了共用缓冲间、独立缓冲间渗透风的来源及患者走道补风的来源,计算和分析了共用缓冲间和患者走道在夏季和冬季分别采用不同的新风状态点送风时对病房内温湿度的影响,并对负压隔离病房新风系统设计提出一些建议。
Abstract：
Taking the floor of the negative pressure isolation ward on the top floor of the emergency building of an infectious disease hospital in Wuhan as an example, the source of infiltration air in the negative pressure isolation ward and the influence of its air treatment state points on the temperature and humidity in the ward are discussed. The sources of infiltration air in the shared and the independent buffer rooms, and the source of the patient corridor supplemental air are studied. The effects of the shared buffer room and the patient corridor on the temperature and humidity of the ward are calculated and analysed when different outdoor air state points are used for air supply in summer and winter. Some suggestions are put forward for designing the outdoor air system in the negative pressure isolation wards.
