method for controlling indoor air quality using ventilating system

摘要

The present invention is to provide a control device and method that can improve the indoor air characteristics through ventilation and air cleaning by configuring the ventilation system and the air purifier as a system and interlocked operation with each other, CO ₂ sensor and dust / gas Inspecting the concentration of carbon dioxide (CO ₂ ) and indoor air pollution of the current indoor air through the sensor; and if the concentration of carbon dioxide (CO ₂ ) is less than a predetermined concentration, the operation of the ventilation system is stopped, and And independently operating the air cleaner through the air cleaner according to the indoor air pollution degree, and if the carbon dioxide concentration is greater than or equal to the predetermined concentration, driving the ventilation system and the air cleaner simultaneously according to the carbon dioxide concentration. It is done by;Ventilation system, air cleaner, carbon dioxide concentration, indoor air pollution
