Abstract
A method comprising detecting an indoor carbon dioxide level; detecting an outdoor fine dust level; driving an air supply fan and an exhaust fan such that an air supply amount of the air supply fan is greater than an exhaust amount of the exhaust fan based on detected indoor carbon dioxide level and outdoor fine dust level; and performing a first indoor pressure control of detecting an indoor pressure and controlling the air supply fan and the exhaust fan. In the indoor pressure control, based on the detected indoor pressure being less than a first set value, a number of revolutions per minute of the exhaust fan is controlled to be decreased, and based on the detected indoor pressure is greater than or equal to a second set value greater than the first set value, the number of revolutions per minute of the exhaust fan is controlled to be increased.
