<p>PURPOSE:To remove dust and acidic gas in air and simultaneously to perform safe and complete deodorization and sterilization irrespective of the presence of a person by providing a device for controlling the ozone generation to outside a unit and the air suction to inside the unit by detecting the human body with a human body sensor. CONSTITUTION:An ozonizer 9, a dust collector, an ozone gas-phase concentration sensor 5, an acidic gas adsorptive filter and a suction exhaust fan 8 are arranged in the same air duct and driving power source part is fitted to outside the air duct. On the same base plate, a control part 14 for controlling the ozone generation to outside a unit and the air suction to inside the unit by detecting the human body with a human body sensor is provided. Dust and acidic gas in air are removed. Simultaneously in the case there is a person, air is taken in the unit to perform deodeodorization and sterilization and the cleaned air is discharged and in the case there is not a person, ozone is directly exposed to the environment. Consequently safe and complete deodorization and sterilization are performed.</p> |
