Abstract:
A ventilation device (1) comprises: an air supply passage (115) through which flows a supply airflow from outdoor to indoor; an exhaust passage (116) through which flows an exhaust airflow from indoor to outdoor; an air supply blower (12) which is provided to the air supply passage; an exhaust blower (13) which is provided to the exhaust passage; an air quality sensor (17) which detects indoor air quality; and a control unit (19) which controls the airflow amounts of the air supply blower and the exhaust blower. The present invention is characterized in that, when there has been an instruction for operation in accordance with an airflow amount difference value, which is information indicating the difference between an exhaust airflow amount instruction value of the exhaust blower and a supply airflow amount instruction value of the air supply blower set externally, the control unit: acquires, for a first blower among the air supply blower and the exhaust blower, a first airflow amount in accordance with the value of the air quality detected by the air quality sensor, said first airflow amount being acquired from airflow amount setting information that defines the relation between the value of air quality and the airflow amount; controls the first blower with the first airflow amount; uses the airflow amount difference value and the first airflow amount of the first blower to calculate, for a second blower which is not the first blower, a second airflow amount; and controls the second blower with the second airflow amount.
