摘　　要：提出了影响病房新风量的两个特征参数——人员数量和人员在室停留时间,结合调研数据,给出了不同科室的人员数量及停留时间特征。提出了抗冲击能力强度与抗冲击时间两个新风供应能力参数,建立了基于此参数的病房新风调控判据。根据算例分析,认为病房新风设计换气次数值宜大于2h-1,并提出了调控策略。Puts forward the two characteristic parameters which influence outdoor air supply of hospital wards, i.e. the number of occupants and the indoor residence time of person. Combining with the survey data, provides the characteristics for the number of occupants and the residence time in different departments. Gives the two outdoor air supply parameters, i.e. impact resistance strength and impact resistance time. Establishes the outdoor air control criterion on the basis of the parameters. According to the analysis of the case, considers that the outdoor air change rate for outdoor air design of the wards should be greater than 2 h-1. And presents the corresponding control strategy.
