摘要

  • 摘要: 研究一种新型电凝并式空气净化单元对室内空气中颗粒物和甲醛的净化效果。实验结果表明,高压高频（HV-HF）电凝并装置能促使小粒子相互凝并为较大的电中性的粒子团，这些具有较高比表面积的电中性粒子团进入室内空间，能继续粘附空气中及物体表面上的颗粒，形成更大的粒子团，从而易于被净化单元中的中效过滤器捕集，而且该净化单元对于大粒子（粒径＞0.7 μm）浓度较高的场所净化效果更加明显。另外，室内空气中吸附在颗粒物表面的甲醛也随之被高效去除。该净化单元的投入使用，起到了提高过滤效率、去除气溶胶小粒子、降低能耗、进一步改善室内空气品质等多重功效。
    Abstract: A new type of electric coagulation indoor air cleaning system was introduced in this paper, and its effect on particles and formaldehyde in indoor air was studied preliminarily. The results showed that particles were collided to form clusters by the drive of electric coagulation device, and the coagulated clusters tended to become larger and larger after the adhesion of particles in indoor air and the surface of object. Therefore, they were quite ready to be captured by the filter of the cleaning system. The air cleaning unit had an excellent effect on the condition of higher concentration of large particles; meanwhile, the formaldehyde adsorbed on the surface of particles was also removed effectively. The tests revealed that the cleaning unit has obvious functions in terms of improving filtration efficiency, removing smaller particles, reducing power consumption and improving the quality of indoor air.
