SYSTÈME DE CONDUIT DE VENTILATION POUR ÉCHANGER AU MOINS UNE PARTIE DE L'AIR DANS UNE SECTION D'ETABLES, OU DANS UN AGENCEMENT D'ETABLES AVEC DES SECTIONS D'ETABLES, ET PROCÉDÉ POUR LE VENTILER
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.
