摘　　要：目的研究空气净化器固态污染物洁净空气量计算方法。方法通过分析3种空气净化器固态污染物洁净空气量的计算方法,研究3种计算方法的异同点;依照标准GB/T 18801-2008空气净化器,在30 m3实验舱内检测不同净化器净化效果,并比较不同计算公式得出的洁净空气量的区别。结果 3种计算方法的主要区别在于测试时间和数据点选取;对于洁净空气量>700 m3/h,用不同公式计算出来的结果差异较大,而对于洁净空气量<700 m3/h,尤其是<500 m3/h的净化器,用不同公式计算出来的结果差异较小。结论 CADR<700 m3/h时,3个固态污染物洁净空气量公式通过可简化换算为CADR(m3/h)=ln(C2t/C20)-(C1t/C10)/t×V×60,且其与GB/T 18801-2008中标准计算公式计算的结果差异较小。Objective To research the CADR computing method of particle matter for air cleaner. Methods Differences and similarities among three computing methods were analyzed; Three air cleaners which had different cleaning efficiency were selected, the CADR was tested in the 30 m3 test chamber, and tile CADR was computed by different computing meth- ods. Results The main differences among the three computing method were test time and data points; There had significant difference when the CADR was more than 700 mS/h, and there was little difference when CADR was less than 500 mS/ h. Conclusion The three computing methods can simplify as, and it has little difference compared with standard formula of GB/T 18801 - 2008.
