内、外循环空气净化系统理论模型构建与性能对比分析
Theoretical model and performance comparison of inner and outer circulation air purification system
摘要
Abstract
The effects of indoor air pollution on human health have caused increasing concern in recent years and generated high interest for air purification systems.In this study, the inner and outer circulation theoretical models were designed for indoor air purifiers and outdoor-air ventilators, respectively.The factors influencing the purifying effects of the two systems were analyzed.The results showed that the indoor air purifiers had a higher PM2.5 removal rate than the outdoor-air ventilators under the same conditions.Both removal rates increased with air volume, primary purification efficiency, and time, and decreased with the volume of the room.The optimum building ventilation frequency was determined for outdoor-air ventilators.Outdoor PM2.5 concentrations did not affect the PM2.5 removal rate of the two air purification systems, but the residual concentration of indoor PM2.5 increased with the outdoor PM2.5 concentrations.关键词
