3. An electrostatic precipitating apparatus for an air conditioning system having a duct with a gas inlet and a gas outlet, the apparatus comprising:
an electrostatic precipitator including a plurality of discharge electrodes to which a voltage is applied and a plurality of electrostatic precipitating electrodes each disposed between the discharge electrodes and grounded;
a washing water supply to spray the washing water to the electrostatic precipitator; and
a frame assembly fixed to the duct to support the electrostatic precipitator, the frame assembly including a prestressing locking member fixed to inside of the duct in a state in which a pressing force is applied to the electrostatic precipitator,
wherein the electrostatic precipitator includes a plurality of first tie rods fixed to the plurality of discharge electrodes to pass through the plurality of electrostatic precipitating electrodes, and a plurality of second tie rods fixed to the plurality of electrostatic precipitating electrodes to pass through the plurality of discharge electrodes,
wherein the frame assembly further includes a plurality of upper supports to which some of the first tie rods are fixed, and
wherein the prestressing locking member is fixedly provided to press the upper support inward.
