AIR CONDITIONING APPARATUS AND METHOD OF CONTROLLING INDOOR PRESSURE USING SAME

WIPO Patent Application WO/2022/059910

A1

A method of controlling an indoor pressure is disclosed. The method comprises: a first detection step of detecting an indoor carbon dioxide level; a second detection step of detecting an outdoor fine dust level; a step of, on the basis of the levels detected in the first detection step and the second detection step, 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; and a first indoor pressure control step of detecting an indoor pressure and controlling the air supply fan and the exhaust fan on the basis of the indoor pressure. In the first indoor pressure control step, when the indoor pressure is less than a first set value, the number of revolutions per minute of the exhaust fan is controlled to be lowered, and when the 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 increase.
