<p>A ventilation duct system (23) in a stable arrangement (1) constructed of stable sections, serves for ensuring improved air quality in stable sections and stable arrangements, respectively, by means of a method for exchanging at least a part of the air in at least a part of a stable section or stable arrangement. The method comprises from a station outside the building supplying a first amount of air to the inner room of the building via at least one first duct extending below the floor of the building (23a) and configured with a number of spaced apart first holes (30) in the longitudinal direction and via at least one second duct extending below the floor of the building (23b) and configured with a number of spaced apart second holes (31) in the longitudinal direction, leading a second amount of air out of the inner room of the building. The cross section of the first and/or the second duct (23a, 23b) is reduced in the direction from the first end of the duct (23a, 23b) towards the second end of the duct (23a). In this way a stable arrangement having an increased production capacity, and a better animal welfare is obtained. The stable arrangement is logistically arranged with short distances of transport during an animal's life cycle, and a cleaner living environment and working environment for animal and farmers.</p> |
