针对传统新风系统PM2。5控制设计中浓度取值单一导致运行能耗高的问题,提出了一种高过滤效率,低运行能耗的新风净化系统,自主研发了室内空气质量监控系统,并将其应用于上海市某办公建筑。测试结果表明,该新风净化系统运行效果良好,室内PM2。5浓度基本满足设计要求,且减少了系统运行能耗。

For improving the indoor air quality, a fresh air system with electrostatic cleaner and HEP-A filters was fixed on an office building located in Changsha, Hunan Province。 The indoor air quality was tested before and after building retrofitting。 The indoor temperature, humidity, CO2 and formaldehyde con-centration, particulate matter are measured and analyzed by Testo435 Air Meter, formaldehyde detector and CW-HPC600 particle detector and other equipments。 The results showed that the CO2 concentration of in-door air was less than 1000ppm, formaldehyde content was less than 0。05 mg/m3, levels of particulate mat-ter was close to 0μg/m3 after retrofitting。 Various parameters are better than the required properties in In-door Air Quality Standard (GB/T 18883-2002)。%为改善建筑室内空气品质,对位于湖南省长沙市一栋办公楼加装带有静电除尘和高效过滤器的新风系统,并对建筑改造前后的室内空气品质进行测试。利用德图Testo435多功能环境测量仪,甲醛检测仪,CW-HPC600颗粒物检测仪等仪器对室内温湿度,二氧化碳浓度,甲醛,颗粒物进行实测分析。结果显示,改造后该建筑室内空气中的二氧化碳浓度在1000 ppm以下,甲醛含量小于0。05 mg/m3,颗粒物的含量接近0μg/m3,远远高于GB/T 18883-2002《室内空气质量标准》的规定。

对好气性发酵空气净化系统提出了节能设计新方案,与传统方案比较研究,指出采用高效率分离器替代一般旋风分离器,用于系统除油水,是简化系统、节约能源的关键。并举例计算论证两方案在工艺上和经济上的优劣。
