以PM2.5设计浓度计算净化风量的方法研究

Study on Method of Calculating Purified Air Volume by PM2.5 Design Concentration in Classroom

净化风量是新风系统设计的重要指标,本文对现阶段常用的净化风量计算方法进行综述,通过小学教室新风系统具体案例比较了各种计算方法,并根据JGJ/T461-2019《公共建筑室内空气质量控制设计标准》,提出了以PM2.5设计浓度计算净化风量的具体方法,为教室内净化风量的合理确定提供计算依据。

Purifying air volume is an important indicator for the design of fresh air system.This paper summarizes the commonly used methods for calculating the purifying air volume at present,and compares various calculation methods through the specific case of the fresh air system in primary school classroom.According to JGJ/T 461-2019<Design standard for controlling indoor air quality of public buildings>,the specific method for calculating the purified air volume with PM2.5 design concentration is proposed.It provides a calculation basis for the reasonable determination of the purified air volume in the classroom.
