摘　　要：受大气颗粒物污染的影响,通过机械通风的方式引入新风时,需要考虑新风中细颗粒物PM2.5的过滤。空气过滤器及热回收装置的应用均会对通风能耗产生影响。本文采用质量守恒及全面通风等基本理论,建立了通风能耗及PM2.5浓度的计算模型,分析了净化效率及室内保证率与通风能耗的关系。Due to the influence of particulate matter pollution in atmosphere,it is necessary to filter fine particulate matter of PM2.5 when using mechanical ventilation to bring in outdoor air.The application of air filter and heat recovery device both effect on ventilation energy consumption.Based on the basic theory of conservation of mass and general ventilation,this paper establishes calculation models of ventilation energy consumption and concentration of PM2.5,and analyzes the relationship between cleaning efficiency and indoor assure percentage and ventilation energy consumption.
