【Abstract】 Horizontal line net electrode structure and negative high voltage supply are utilized to create negative ions which are good to our health. The method of heating corona line is applied to the decrease of ozone creating and the concentration of negative ions which are harmful to our health. The results are that heating corona line is beneficial to corona discharge; in the same voltage, with the increasing of appearance temperature of corona line, the negative ions flow also increases; under the condition of regular negative ion flow, heating corona line can decrease ozone creating and the concentration of closed indoor negative ions. The prototype can meet the specification of negative ions (10 2/cm 3) and mass concentration of ozone (120 μg/m 3).更多还原
