Method and device for defrosting or deicing heat exchangers of the type in which a stream of warm, moist gas, such as warm, used ventilating air--so-called exhaust air--exchanges heat with a cooler medium, such as incoming fresh air, in a contact apparatus, and in which the two media flow through a large number of parallel layers separated from each other by thin walls.
