等离子体空气净化器去除室内尘埃颗粒性能测试研究

目的 通过对LG电子公司两种类型等离子体空气净化器去除尘埃颗粒的性能进行测试，探索较为科学合理的室内空气净化器净化效果的评价方法，使测试的实验数据和计算结果具有科学性和可比性。方法 参照ANSI／AHAMAC-1-2000(美国家用便携式室内电动式空气净化器检测标准方法》，采用其中洁净空气量(CADR)作为空气净化器净化效果的主要评价指标，同时也选用了国内外常用的几种净化器性能评估指标对其性能进行综合评价。结果 CADR能较准确、客观地体现空气净化器的真实净化性能。而用净化率说明空气净化器净化能力时要考虑到污染物的自然衰减率和初始浓度对其影响，并同时给出其他的试验条件。结论 建立正确的测试方法和正确的测试结果表示法是正确评价测试对象的充分必要条件。

Study on Testing of the Indoor Particle Removal Efficiency of Plasma Air Cleaner

Objective By testing the particle removal efficiency of LG Electronics Company's two types of plasma air cleaners,to explore more scientific and reasonable methods for evaluating the purifying effectiveness of indoor air cleaners so as to obtain scientific and contrastable experimental data and calculating results. Methods This evaluating method referred to Standard Examination Method of Portable Household Electric Cord-Connected Room Air Cleaners of America (ANSI/AHAM AC-1-2000) and used one of indexes regu lated in standard Clean Air Delivery Rate (CADR) as the main evaluating index of the effectiveness of indoor air cleaners,meantime several kinds of domestic and international current evaluating indexes were adopted to synthetically evaluate decontaminating function of the air cleaners. Results The index of CADR could accurately and objectively manifest the true decontaminating function of indoor air cleaner. But if using the index of purifying efficiency to reflect the purifying effectiveness of air cleaners,pollutant's natural decay rate and initial concentration should be considered and at the same time other experimental conditions should be given out. Conclusion The establishments of accurate testing methods and accurate expressions of testing results were the sufficient and essential conditions for accurate evaluation on testing objectives.
