ABSTRACT:
A method for adjusting an opening cross section of an air inlet into a premises involves sensing the amount of water vapor contained in the air inside of the premises and the amount of water vapor in the air outside of the premises. The opening cross section is adjusted on the basis of at least one of a difference between the amount of water vapor sensed the inside and outside the premises so that the opening cross section increases when the difference increases and independently of the amount of water vapor in the air outside the premises. A device for adjusting an opening cross section of an air inlet into a premises includes two chambers in communication respectively with the air outside and with the air inside the premises, the chambers being separated from one another by a heat exchanger, which is impervious to water vapor. Each chamber contains a bundle of fibers sensitive to humidity and is kept under tension by a spring and is connected by a driving mechanism to at least one flap for adjusting the cross section of the opening for inlet of air into the premises.
