Abstract
Provided is an air conditioning apparatus. The air conditioning apparatus includes a main body having a suction part through which air is suctioned and a discharge part through which the air suctioned through the suction part is discharged, a fan disposed within the main body to allow the air to flow, a filter device disposed between the suction part and the discharge part within the main body, the filter device including a filter including a plurality of arrays that are spaced apart from each other, and a power supply part to supply a voltage to each of the arrays. Each of the arrays includes a conductive member, the conductive member contacts a dielectric containing a dielectric material.
Claims8
An air conditioning apparatus comprising:
- a main body having a suction part and a discharge part, air being suctioned through the suction part and discharged through the discharge part;
- a fan within the main body to allow the air to flow;
- a filter device between the suction part and the discharge part within the main body, the filter device comprising an array of filter elements separated from each other,
- each of the filter elements comprises a conductive member that contacts a dielectric containing a dielectric material;
- and
- a controller to control a power supply that supplies a voltage to more than one of the filter elements,
- wherein the controller controls the power supply such that:
- the power supply supplies a first voltage having a first frequency to the more than one of the filter elements to filter dust, the first frequency being less than 1 Khz, and
- the power supply supplies a second voltage having a second frequency to the more than one of the filter elements for cleaning, the second frequency being greater than 1 Khz.
