The invention relates to a mixer, which forms the core part of an air-conditioning assembly of a rail vehicle, and to the corresponding air-conditioning assembly. The mixer (M11) has two inlets (E11,E12), an outlet (A11), and a central region (B11) which is arranged between the two inlets (E11, E12) and the outlet (A11). The first inlet (E11) is connected to a fresh air supply, and the second inlet (E12) is connected to a circulating air supply such that fresh air (FL) and circulating air (UL) reach the central region (B11). The circulating air (UL) is mixed with the fresh air (FL) in the central region (B11), and supply air (ZL) is thus obtained. The central region (B11) of the mixer (M11) is connected to the fresh air inlet (E11) via an opening (OF11) such that the opening (OF11) formsa transition region (UB11) between the fresh air inlet (E11) and the central region (B11). The transition region (UB11) contains a profiled section (PR11) with a wing-shaped cross-section which is designed and arranged in the transition region (UB11) such that the supplied fresh air (FL) generates negative pressure along the transition region (UB11), and the circulating air (UL) is suctioned intothe central region (B11) of the mixer (M11) in a reinforced manner via the negative pressure.
本发明涉及一种混合器,所述混合器构成轨道交通工具的空气调节装置的核心部件,本发明还涉及相应的空气调节装置。所述混合器(M11)具有两个入口(E11、E12)、出口(A11)以及中部区域(B11),所述中部区域布置在两个入口(E11、E12)和出口(A11)之间。所述第一入口(E11)与新鲜空气输入装置连接,所述第二入口(E12)与循环空气输入装置连接,从而使新鲜空气(FL)和循环空气(UL)到达中部区域(B11)。在所述中部区域(B11)中,循环空气(UL)与新鲜空气(FL)混合并且由此得到送风(ZL)。所述混合器(11)的中部区域(B11)通过开口(OF11)与新鲜空气入口(E11)连通,因此所述开口(OF11)构成新鲜空气入口(E11)和所述中部区域(B11)之间的过渡区域(UB11)。所述过渡区域(UB11)包含具有翼状横截面的型材(PR11),所述型材(PR11)这样设计并且布置在过渡区域(UB11)中,使得输入的新鲜空气(FL)沿着所述过渡区域(UB11)产生负压,循环空气(UL)通过所述负压被增强地吸入混合器(M11)的中部区域(B11)中。
