  • Recentely, a compact and small size air-cleaning Electrostatic Precipitator(ESP) is needed to develop for air conditioning devices. From Deutsch formula for ESP efficiency, collection efficiency is affected not only the structure of collection section but also the charge rate of dust. In terms of collection area, the most useful type is a scroll type ESP. In this work, we investigated experimentally aptimum design factor of scroll type ESP by application of Taguchi method. And we developed the scroll type ESP by using optimal condition of control factor.

  • In order to develop a thin type ESP(Electrostatic Precipitator) for high efficient air-conditioner with low concentration of ozone generation, collecting electrode spacing should be narrower than that from Deutsch formula and minimizes discharge current in ionizer. In this paper, the effect of applied voltage on the precipitation efficiency and ozone concentration of scroll type ESP was studied. As a result, precipitation efficiency(one pass) was improved by about 30[%] from increment of collector voltage(3.5[㎸]). Precipitation efficiency was increased with increasing ionizer voltage. And after some point, the efficiency was saturated. At the point, voltage and ionizer current was 5.2[㎸] and 95$[\muA]$ per meter respectively. At these applied voltage conditions, ozone concentration was saturated about 0.01[ppm] after 3 hours in 23$[m^3]$ closed room test.
