Parametric Study of Wet Electrostatic Precipitator Applied to Ducted Heat Pump System

In this paper, parametric study of wet electrostatic precipitator applied to ducted heat pump system was conducted. For the experiment, a dust collecting module was designed and a prototype was manufactured. The airflow rate, the applied voltages of the charging and collecting part were selected as the main parameters in the limited condition. The dust collection efficiency was measured according to the change of the parameter values and the influence of each parameter was analyzed. As a result, the contribution of each parameter on the dust collection efficiency was analyzed as 22.7% airflow rate, 6.6% applied voltage in charging part and 69.9% applied voltage in collecting part. And it was found that the applied voltage of the dust collecting part had the greatest influence on the dust collection efficiency. The correlation equation was derived using the parameters and the product design was made considering this. This design and analysis process will be helpful in future large-scale design.
