    摘要： 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.

    摘要： A ventilation duct system (1,24,34) and method serve for minimizing air pollution in and/or around an animal habitat structure (25,33,52) with at least one animal habitat surface (3). The ventilation duct system (1,24,34) is located at least partly below the at least one animal habitat surface (3) and comprises waste receiving means (2) configured for receiving waste (17,20,32) from and/or through at least a part of the at last one animal habitat surface (3). The ventilation duct system (1,24,34) provides an air pressure gradient across the width of the waste receiving means (2), which air pressure gradient is generated by a pressure difference between a first long side (10) and an opposing second long side (11) of the waste receiving means (2). The ammonia concentration is almost completely kept at floor level and in the slurry pits, and the breathing air in the room above the slatted floor is thus ventilated without admixing the unpleasant gases from the animals.
