摘　　要：通过实验的方法测试了风机盘管加装过滤器对病房空气的净化效果。选取2家医院,分别随机选取1间实验病房和1间对照病房,实验病房风机盘管加装过滤器,对照病房风机盘管不加过滤器。测试结果表明:医院1实验病房细颗粒物(PM2.5)质量浓度平均为63μg/m^3,浮游菌浓度平均为196cfu/m^3;对照病房PM2.5质量浓度平均为262μg/m^3,浮游菌浓度平均为368cfu/m^3。医院2实验病房PM2.5质量浓度平均为45μg/m^3,浮游菌浓度平均为272cfu/m^3;对照病房PM2.5质量浓度平均为105μg/m^3,浮游菌浓度平均为479cfu/m^3。说明风机盘管加装过滤器可有效降低医院病房内PM2.5浓度和浮游菌浓度。Researches the indoor purification efficiency of fan coil unit(FCU)with filters in ward by experimental method.Taking two hospitals as examples,randomly selects one experimental ward and one contrast ward in each hospital.The FCU in experimental ward installs the filter and the FCU in contrast ward has no filter.The testing results indicate that in the first hospital,the concentration of fine particle matter(PM2.5)is 63μg/m^3 and the concentration of airborne bacterium is 196 cfu/m^3 in experimental ward,while the value in contrast room is 262μg/m^3 and 368 cfu/m3 respectively.In the second hospital,the corresponding values are 45μg/m^3 and 272 cfu/m3 in experimental ward and 105μg/m^3 and 479 cfu/m^3 in contrast ward.Demonstrates that FCU with filter can efficiently decrease the concentration of PM2.5 and airborne bacterium in the ward.
