APPARATUS FOR AIR PURIFICATION AND CONTROL METHOD THEREOF

摘要

The present invention relates to an air purification device which purifies the air by heating a filter part using a heater, the filter part including an inorganic film having a plurality of air holes and a catalytic layer formed by immersing a part or an entire part of the inorganic film in a catalytic mother liquid. The air purification device of the present invention comprises: an air inflow hole; an air purification module including the filter part which can circulate the air received from the air inflow hole and in which the inorganic film having the air holes is formed at a surface thereof and the catalytic layer is formed by immersing a part or an entire part of the inorganic film in the catalytic mother liquid and the heater which purifies the air by causing a catalysis between the air received through the filter part and the catalytic layer by heating the filter part under a predetermined temperature condition; an air discharge hole for discharging the air passed through the air purification module; a ventilation induction fan for inducing the air to sequentially pass through the air inflow hole, the air purification module and the air discharge hole; and a control unit for controlling an operation of the heater and the rotational speed of the ventilation induction fan.
