SPACE VENTILATING METHOD AND APPARATUS

摘要

A method and a device for ventilating a room, wherein an air passage is opened or closed to a particular degree by means of a ventilation valve in dependence on at least one measurement made by means of at least one sensor (12, 16). Before the measurement is made by means of the sensor (12, 16), the air passage is closed by means of the ventilation valve. Then a predetermined waiting period is preferably observed, and subsequently the measurement is made by means of the sensor present (12, 16) in the room. Following that the ventilation valve is opened or kept in its closed position in dependence on a value ensuing from said measurement.
