Definitions

  • FIG. 1 This document shows a comparable passenger compartment ventilation for a coach. The air blown into the coach is drawn off again via grates located near the ground.
  • the documents US 2,305,075 and US 2,120,433 reveal ventilation systems for refrigerated trucks. These ventilation devices are designed to cool perishable goods and are not suitable for indoor air conditioning for passenger transport.
  • FIG. 1 another ventilation device 102, 104 common for interior spaces 100 of rail vehicles.
  • the arrows in FIG. 1 The inlet 102 and the outlet 104 of the ventilation device are each formed by an opening which is located approximately in the middle of a side wall 106, 108 of the interior 100.
  • the outlet is formed by a plurality of second openings, which are distributed over the surface substantially over the entire surface of a second wall, and that this second wall is opposite the first wall and the floor, the ceiling or a Sidewall of the interior forms.
  • the air is discharged through a plurality of widely distributed openings from the interior and these outlet openings are arranged opposite the inlet openings, arises in the interior of a broad, flat and straight air flow low speed or low momentum from the air inlet to the air outlet.
  • the low speed and the areal distribution on the one hand ensure lower energy consumption during ventilation and on the other hand a pleasant indoor climate for people (passengers and train drivers).
  • the noise is lower than in the conventional mixing ventilation.
  • the inlet when the interior is ventilated, a supply air layer is formed over the wall, which layer then moves through the interior and displaces the air present therefrom out of the interior.
  • the air in the interior is replaced quickly and more effectively than in the mixing ventilation.
  • the effect of the source ventilation can be exploited. That is, the air is heated by the natural convection of the internal thermal loads such as persons present, and finally moved.
  • the invention likewise relates to a method for operating the ventilation device of the above-defined rail vehicle, characterized in that the supply air is introduced at a speed of less than or equal to 0.2 m / s via the inlet into the interior.
  • the present invention is concerned with the ventilation of the interior of rail vehicles, such as e.g. Railcars, passenger cars or locomotives.
  • rail vehicles such as e.g. Railcars, passenger cars or locomotives.
  • the basic idea of the invention is to air-condition the interior of a rail vehicle thanks to displacement ventilation, such as a displacement ventilation.
  • displacement ventilation such as a displacement ventilation.
  • FIGS. 2 to 4 show by way of example various possible embodiments of such displacement ventilation.
  • FIGS. 2 to 4 a person P receiving the interior 200 of a rail vehicle is shown in cross section.
  • the interior 200 may be z. B. act to a passenger compartment or the driver's cab of the driver.
  • the interior 200 is equipped with a ventilation device which has an inlet 203 for introducing supply air into the interior and an outlet 205 for discharging exhaust air from the interior.
  • the inlet is realized in the form of a multiplicity of first openings 203, which are distributed over substantially the entire surface of a first wall 202, this first wall 202 forming the bottom, the ceiling or a side wall of the interior 200.
  • the outlet is formed by a multiplicity of second openings 205, which are distributed over the entire area essentially over the entire surface of a second wall 204, this second wall 204 forming the bottom, the ceiling or a side wall of the interior 200.
  • the first wall 202 and thus the air inlet 203 lie opposite the second wall 204 and thus opposite the air outlet 205.
  • the ventilation device also comprises an air-guiding first cavity 206 located behind the first wall 202 for supplying the first openings 203 with supply air ZL, which extends over the entire surface of the first wall 202.
  • the ventilation device also includes an air-conducting second cavity 208 located behind the second wall 204 for receiving the exhaust air AL from the second openings 205, which extends over the entire surface of the second wall 204.
  • the first wall 202 forms the bottom of the interior 200 and the second wall 204 forms the ceiling of the interior 200.
  • the air inlet 203 is formed by a plurality of preferably evenly distributed over the bottom openings.
  • the air outlet 205 is realized in the form of a plurality of openings preferably uniformly distributed over the ceiling.
  • the first wall 202 forms the ceiling of the interior 200 and the second wall 204 forms the bottom of the interior 200.
  • the air inlet 203 is formed by a plurality of preferably evenly distributed over the ceiling openings.
  • the air outlet 205 is realized in the form of a plurality of openings which are preferably evenly distributed over the bottom.
  • the first wall 202 forms a first side wall of the interior space 200.
  • the second wall 204 forms a second side wall of the interior space 200, which is opposite the first side wall.
  • the air inlet 203 and the air outlet 205 are formed by a plurality of openings preferably uniformly distributed over one of the side walls. The air flow can either flow from left to right or vice versa.
  • the first and / or the second wall 202, 204 at least one access 210 to the first and second cavity 206, 208 on.
  • the FIGS. 5 to 7 show possible embodiments of the entrances 210.
  • the entrances 210 may be realized, for example, in the form of access doors. Thanks to the entrances 210, the corresponding cavity 206, 208 is easily accessible. Therefore, this can be inspected or cleaned at any time, without having to disassemble consuming panels of the interior.
  • the hygiene requirements from the standards VDI 6022 and VDI 6032 can be realized more easily with the additions 210 than with conventional air duct systems, which are usually located behind panels / coves.
  • the ventilation device according to the invention generates a displacement ventilation and in particular a displacement ventilation of the interior 200.
  • the corresponding air flow is in the FIGS. 2 to 4 represented by arrows.
  • the air to be introduced into the internal space 200 is brought into the first cavity 206.
  • the air in the cavity 206 in the form of supply air ZL is blown through the air-permeable first wall 202 at low speed and high total volume in the interior space 200.
  • the supply air flow ZL displaces the interior air IL present in the interior 200 in the direction of the outlet 205.
  • the interior air IL then leaves the interior 200 in the form of exhaust air AL through the outlet 205.
  • the exhaust air AL reaches the second cavity 208 after passing through the second wall 204.
  • the ventilation efficiency of the interior 200 can double from 0.5 to 1.0 and thus improve compared to the mixing ventilation previously used.
  • a source ventilation is preferably generated in the interior 200. This is achieved in that the supply air ZL is supplied to the interior 200 via the inlet 203 at a speed of less than or equal to 0.2 m / s and with an under temperature of 2 to 4 Kelvin. In other words, the supply air ZL is injected at a temperature T ZL into the interior 200, which is 2 to 4 Kelvin below the current interior temperature T IL , so that the interior space 200 is cooled. In the interior 200 thereby set vertical density and temperature gradients. The air velocity in the interior 200 itself is then approximately between 0.04 to 0.08 m / s, because the flow is largely generated by the natural buoyancy thermics.
  • FIG. 8 shows an example of a cab 211 with a ventilation device according to the invention.
  • the air-permeable first wall 202 is formed here as the bottom of the interior 200 of the cab 211. This floor 202 is covered with an air-permeable carpet 212. It can be seen behind the bottom 202, the first cavity 206th
  • the displacement ventilation according to the invention ensures a smooth, swirl-free and distributed over a large area air flow, which is perceived by the people located in the interior of the rail vehicle as very pleasant (increased comfort compared to mixing ventilation).
  • this air flow causes a uniform distribution of hot air in the interior without overheated areas, as they occur in the mixing ventilation in the vicinity of the inlets, because the supply air is introduced over the entire interior surface of the vehicle.
  • the said air flow provides a pleasant cooling without cold draft, as occurs in the mixed ventilation, because the effect of natural convection can be exploited.
  • the displacement ventilation according to the invention also has the advantage that it can be used to meet the climate and temperature requirements of the relevant standards (EN 13129, EN 14750 and EN 14813).
