摘　　要：为了降低传染性疾病在隔离病房传播感染的风险,给医护人员创造安全舒适的工作环境,以单条缝贴附送风、对侧条缝贴附送风、百叶风口送风以及置换送风4种送风形式为例对隔离病房的人体热舒适性、咳嗽液滴的排除效果及医护人员的感染风险进行了模拟研究。结果表明:在满足病人和医护人员热舒适性要求下,与其他3种送风形式相比,在置换送风的送风形式下,隔离病房的小粒径咳嗽液滴(5μm~50μm)排除效果最好,医护人员的感染风险最低,建议隔离病房采用置换送风的送风形式。In order to reduce the risk of infectious diseases in the isolation ward transmitted infections,and create a safe and comfortable working environment for medical staff,with a single seam tape attached to the wind,the contralateral to sew sticker attached to the wind,shutter tuyere air supply and replacement air distribution form of four kinds of air supply as an example to the isolation ward of the human body thermal comfort,cough drops out effect and medical personnel simulation research was conducted on the risk of infection.Results show that the meet the requirements of thermal comfort of patients and medical workers,compared with other forms of three kinds of air supply,in replacement of air supply air distribution form,the small particle size of the isolation ward cough drops(5μm~50μm)ruled out the best effect,medical staff the lowest risk of infection,suggested that the isolation ward in the form of displacement air supply.
