负压病房防护通风设计要点及影响因素分析

The Key Points and Influence Factors of Protective Ventilation Design in Negative Pressure Isolation Ward

从压力梯度确定、换气次数计算、渗透风量计算、房间送、排风量计算四个方面,系统分析了负压隔离病房防护通风的设计方法和步骤。同时结合实际工程项目,总结了负压病房风量计算时其他主要的影响因素。为负压病房类项目的防护通风设计提供了一定的参考意义。

Systematically analyzing the design method and steps of protective ventilation in negative pressure isolation wards from four aspects: determination of pressure gradient, calculation of ventilation rate, calculation of infiltration air volume and calculation of room air supply and exhaust volume.At the same time, combined with the actual project, summed up the negative pressure ward air flow calculation of other major factors.This paper provides a reference for the ventilation design of negative pressure wards.
