PURPOSE:To provide an atmosphere treating system which can substantially effectively introduce a necessary quantity of the atmosphere. CONSTITUTION:An atmosphere treating system introduces temperature regulated and/or humidity regulated atmosphere into a building by an atmosphere treating unit and exhausts the air of substantially the same quantity as that of the introduced atmosphere by an exhaust fan out of the building. The system comprises atmosphere introducing means 300 for introducing the atmosphere, and a controller 220 for driving the means 300 when the atmosphere to be introduced by the unit 11 is less than the air to be exhausted by exhaust fans 200a-200c, wherein it is so controlled that an interior in the building does not become a negative pressure.
