known to be the problem, especially in cooling;

of drafts. Because the demand for cold air distribution Naturally, over the entire passenger compartment when the supply air is blown upwards a relatively high blowing speed. Corresponding would have to work with a high blowing speed with roof-side air supply in heating mode become with the inevitable consequence of harassment the passengers.

The invention is based on the object of a '

on the other hand, the Abte i I -Ro i .so / iigwagcn with such openings on both AbLei I walls in the sense of the Fr / .ougung A separate air supply circuit in each of the two halves of the room on both sides the abbot is provided with a longitudinal central obono. This is explained below using exemplary embodiments the invention and further embodiments explained in more detail. The drawing shows this only schematically in

Fig. 1 is a cross section through the car body of a Big p * i um passenger coaches,

2 shows a cross section through the car body of an Abbey 1 passenger coach,

3 shows the compartment according to FIG. 2 in cross section.

The passenger compartment of a passenger coach shown in FIG. 1 with seats separated by an open aisle J on both sides of the car I longitudinally divided 2, so one So-called. Large area is about two in the car roof space of the car length after extending air ducts 3 with one not shown with fresh air supplied by the air conditioning unit connected, ζ. 15. a known P. unit from a Kompressorkä 1 temasch i no, air filters, an evaporator, air heaters, Fans and the like.

The distribution boxes 18 can be at If there is sufficient space, they can also take over the function of supply air and distribution ducts 3 and 4, i.e. the latter can then be saved as such will. The air injection openings 5 are preferably aligned on the floor of the ceiling-side (small) luggage racks so that they fulfill a guiding function for the blown air; otherwise the respective air inlet opening can also be placed above the luggage

be positioned directly on the ceiling 7 from J agc. By pairing these openings 5 with an air suction opening 8 positioned near them on the side wall of the car, in the manner illustrated by the arrows in each half of the passenger compartment, an air circulation that rotates inwards is created, with the exhaust air being the Air suction 8 reaches the air conditioning unit via a circulating air duct 9; The remaining roof space is preferably used as an air return. At. Such an air circulation, like air circulation, prevents the passengers from being burdened by blown air as far as possible, whereby the illustrated generation of two counter-rotating air rollers, i.e. a separate supply air circulation in each of the halves of the room on both sides of the longitudinal mid-plane 2 odor annoyance of the passengers one half of the room, for example, by smoking passengers in the other half of the room, reduced to the lowest possible level. Air pollutants are not dragged away, but sucked off in the shortest possible way.

According to FIGS. 2 and 3, such air conditioning is just as suitable for compartment passenger coaches, whereby according to FIG Abbey 11 longitudinal center plane 11 are preferred. In this case, 2 Exhaust air through ventilation grille · 12 can according to FIG. Guided in the carriage side passage and been used herein for air-conditioning under suction on the one hand in the relevant clarhse i (.

The possibility of exhaust air suction on the floor isfc so 1 bs-t understoodJ I can also be implemented within the compartment through a corresponding exhaust air duct 14, whereby (except for ventilation grilles) additionally connected air suction openings 15 are preferably arranged below the seat surfaces of the two rows of seats, e.g. via branch lines; this arrangement greatly increases the effectiveness of the compartment air purge. The exhaust air could of course also be used for underfloor heating, as indicated in FIG Are to be connected to passenger coaches. The thus simultaneously achieved air conditioning of underfloor space reduces heat losses, the resultant through the air injection pressure in the underfloor space ingress of contaminants verhindert.Sofern the aforementioned air conditioning unit is designed for appropriate pressure there at the same time a large extent, possible to dispense with the aforementioned bottom-side suction of air, ie Air openings on the floor are sufficient for the mere removal of exhaust air.
Of course, with an appropriate arrangement of the air injection and air suction openings, if necessary, in the compartment, such as. in the greater area, an air circuit directed at right angles to the longitudinal axis of the wagon creates Vierdon. In all cases, the pairing principle according to the invention of air injection and air extraction openings 5, 8 on the roof or ceiling side results in the induction of air-conditioning air rolls with intensive air purging of the respective passenger compartment unit.

The air can also be blown in according to the injection principle.
