摘　　要：参照国标搭建了室内空气净化器的性能测试台,并提出单位面积净化量ms、单位时间净化量mt、单位时间单位面积净化量m等3项性能评价指标。通过试验分别检测TiO2光触媒、ACF活性炭纤维及TiO2/ACF复合材料的净化性能,并将测试数据按这3项指标进行整理计算,结果验证了指标的便利性和直观意义。The present paper is engaged in a research for the evaluating indicators of the room-conditioning air cleaners. The current situation is that, although the room-conditional air quality control is very important, the air cleaning technology for the time being is far from being perfect because much remains to be improved in modern air conditioning systems. In addition, Due to the practical application of the limitations and complexity of air cleaning technology, there has not so far been systematic and comprehensive evaluation methods to air cleaners. Therefore, in order to further standardize the cleaning products, the markets concerned, it is necessary to promote healthy and orderly development of the standardized air cleaners, and carry out a series of research work on the air cleaners and the related materials, and advanced cleaner＇s performance evaluation methods. Cherishing this purpose, we have done a series of work in developing such materials as TiO2 photocatalyst, activated carbon fiber（ACF）and composite materials TiO2/ACF through careful and conscientious comparison and selection. In reference to the relevant national standards, we have built up an air-cleaning performance test unit of air-conditioning systems. Corresponding measures of good air tightness have also been taken to ensure the desirable results during the standard performance tests and found that the room-conditioning interior air purification level is strongly influenced both by the natural attenuation and cleaning devices. Although the natural attenuation of contaminants inside the room is relatively weak, the cleaning performance test should be excluded as a rule, for its capacity can be acquired by testing the concentration change of such contaminants as the respirable particulate matters and formal dehydrates passing through the cleaner. The other three indicators for air cleaners, that is, the cleaning capacity per unit area ms, the cleaning capacity per unit mt, and that per unit area per unit time m have been raised, which are
