| 摘 要： | 在对民用建筑通风系统常用过滤器滤料性能测试基础上,建立了常规风机盘管加新风系统空调房间室内颗粒物浓度集总参数模型,讨论了回风过滤段和新风过滤段过滤器效率的设计选型方法。以西安市某空调系统为例,为满足室内PM2.5污染控制标准,基于室外PM2.5浓度"不保证10d"取值计算,结果表明,余压为50~80Pa的机组回风过滤器效率选用G3、G4型过滤器,余压为30~50Pa的机组回风过滤器效率选用初效G2、G3型过滤器,同时,室内设置等效过滤效率的空气净化器,新风选用初效G4加中效F7或F8两级过滤。

| Abstract: | A theoretical and experimental measurement analysis on air filter of fan coil unit and fresh air system was conducted through establishing a mass balance equation.In this paper,a certain building in Xi'an is taken as an example,the outdoor PM2.5 concentration is calculated based on "no assurance of 10 days".The results show that the synthetic fiber of G3 or G4 air filter can be used in return air of FCU when the fan pressure is 50-80pa,and the G2 or G3 air filter can be used when the pressure is 30-50pa.Meanwhile,G4 and F7 or F8 two-stage filtration can be used in fresh air system when equivalent filtration efficiency air purifier should be installed. |
