基于室内PM2.5控制和节能的通风策略探讨
Ventilation strategies based on PM2.5 and energy-saving
摘要
Abstract
Outdoor haze particles (PM2.5) enter indoor environments with fresh air.Human beings can consequently be exposed to fine particles combined with other indoor PM2.5 sources.In order to maximize indoor air quality while minimizing energy consumption,a dual-component model involving indoor PM2.5 concentration and CO2 fraction was established in this study.Optimal ventilation strategies applied in meeting rooms were studied with various indoor-outdoor PM2.5 sources and persons,and under various weather conditions.Various strategies were modeled by a simulation system using indoor PM2.5 sources during hot and mild weather.The results showed that minimum outdoor air rate was determined by indoor human behavior during hot weather.In addition,filtering supply air can receive maximize air quality about controlling indoor PM2.5.Furthermore,maximum outdoor air rate was proportional to filter efficiency during mild weather.Therefore,potential energy saving during mild weather is larger than during hot weather.关键词
