| 中文摘要: |
| 空气净化器可有效改善雾霾天气下室内空气质量，颗粒物去除效果与洁净空气量(CADR)是衡量其性能的主要参数。在典型室内环境下，以香烟源颗粒物为目标，开展空气扰动对净化器去除颗粒物效果和CADR的影响实验与评价分析。结果显示，在室内空气扰动下，净化器对粒径≥5 μm的颗粒物去除率为756%，在无空气扰动情况下的去除率为466%。空气净化器对粒径03 μm～5 μm的颗粒物有较好的去除效果，而对于粒径10 μm的较大颗粒物，空气扰动造成CADR增加。空气扰动在一定程度上提升了空气净化器的净化能力，同时在性能方面也存在影响 |
| 英文摘要: |
| Air cleaner effectively improved indoor air quality in hazy weather， particle removal effect and clean air delivery rate (CADR) were the main parameters in measuring its performance. In this paper， targeting the cigarette source particles， the effect and evaluation of air disturbance on particulate removal and CADR of air cleaner were carried out in a typical indoor environment. The results indicated that the removal rate was 756% with indoor air disturbance when the particle size was not less than 5 μm， while the removal rate was 466% without air disturbance. The air cleaner had high removal efficiency when the particle size was 03 μm ～ 5 μm. When the particle size was more than 10 μm， CADR increased by air disturbance. To a certain extent， indoor air disturbance improved the purification ability of air cleaner and also affected its performance. |
