<p>A ventilation system where, in ventilating multiple rooms, the volume of airflow can be kept constant independent of the kind and length of ducts. The ventilation system has a differential pressure sensor and is constructed such that air is sucked from a first suction grill, second suction grill, and third suction grill that are provided in a living room and toilet and also from a suction opening provided in a louver at the lower surface of a body.The sucked air is discharged to the outside air through a discharge duct, from a discharge opening in a living room wall surface. By the use of the differential pressure sensor, a required ventilation airflow volume is controlled to be constant independent of the kind and length of the ducts.</p> |
