摘　　要：利用研制的多功能环境试验舱提供相对独立和稳定的环境条件,以甲醛为挥发性目标污染物,对所选取的代表性空气净化器的甲醛净化效果进行测试,计算了空气净化器对甲醛的洁净空气量,净化效率和去除率等。结果表明,空气净化器对甲醛净化效率随着相对湿度的增大而明显降低,随着空气流速的增大而有所提高,而室内温度对其影响并不明显。采用物理和化学净化技术相结合的空气净化器的甲醛净化效率明显优于采用单一的物理吸附净化技术的空气净化器。By using formaldehyde as the objective volatile pollutant, the purification efficiencies of somerepresentative air purifiers were determined under the relatively independent and stable environmental conditions supplied by the self-made multifunctional environmental test chamber. The clean air delivery rate（CADR） ,purification efficiency and removal rate of formaldehyde were also calculated based on the tested results. It was found that the formaldehyde purification efficiency obviously decreased with enhancing the relative humidity, and gradually increased with enhancing the air flow rate, whereas the effect of temperature on the purification efficiency was limited. Moreover, the air purifier based on integration of manifold purification techniques showed better purification efficiency as compared to that based on single adsorption purification technique. The above results indicate that keeping indoor dryness and ventilation as well as integrated manifold purification techniques are beneficial for the improvement of purification efficiency.
