<p>PROBLEM TO BE SOLVED: To provide a method and device to prevent snow particles, etc., from being sucked into an air conditioner, which almost totally can prevent snow particles and water drops from flowing into the suction duct of an air conditioner without increasing the ventilation resistance of the air conditioner. SOLUTION: At the suction part of a duct for air conditioner, a high voltage electrode 2 and a grounding electrode 3 are provided. Then, by applying a high voltage to the high voltage electrode 2, a corona discharge is generated between the high voltage electrode 2 and the grounding electrode 3, and snow particles 5, etc., are electrically charged when the snow particles 5, etc., pass between the high voltage electrode 2 and the grounding electrode 3. Then, the snow particles, etc., being caught by the grounding electrode 3 by the static electric power, are shaken off by a vibrator 4.</p> |
