Ventilating device

摘要

In a ventilating device for stalls, a draught-free extraction of air is achieved in that an intermediate floor with one or more air-conducting floor mats is constructed with a surface proportion of openings sufficient for a limited air resistance, and furthermore in that the boundary of the interspace on the floor side has a heat insulation layer and that the interspace is connected to the outer air via air inlet openings with adjustable throughflow cross-sections. The draught-free ventilation thus has a large regulating range and a small air resistance, so that the ventilation can make do with very small cost in apparatus and power requirement, even if forced ventilation cannot be dispensed with.
